Zorro shares a report from the Smithsonian: A recent study used machine learning technology to analyze eight leading models of human origins and evolution, and the program identified evidence in the human genome of a "ghost population" of human ancestors. The analysis suggests that a previously unknown and long-extinct group of hominins interbred with Homo sapiens in Asia and Oceania somewhere along the long, winding road of human evolutionary history, leaving behind only fragmented traces in modern human DNA. The study, published in Nature Communications, is one of the first examples of how machine learning can help reveal clues to our own origins. By poring through vast amounts of genomic data left behind in fossilized bones and comparing it with DNA in modern humans, scientists can begin to fill in some of the many gaps of our species' evolutionary history. "The new data suggest that the mysterious hominin was likely descended from an admixture of Neanderthals and Denisovans (who were only identified as a unique species on the human family tree in 2010)," the report adds. "Such a species in our evolutionary past would look a lot like the fossil of a 90,000-year-old teenage girl from Siberia's Denisova cave. Her remains were described last summer as the only known example of a first-generation hybrid between the two species, with a Neanderthal mother and a Denisovan father."

"At midnight on New Year's Eve, all works first published in the United States in 1923 will enter the public domain," reports Smithsonian Magazine. "It has been 21 years since the last mass expiration of copyright in the U.S.

"After January 1, any record label can issue a dubstep version of the 1923 hit 'Yes! We Have No Bananas,' any middle school can produce Theodore Pratt's stage adaptation of The Picture of Dorian Gray, and any historian can publish Winston Churchill's The World Crisis with her own extensive annotations." From the report: "The public domain has been frozen in time for 20 years, and we're reaching the 20-year thaw," says Jennifer Jenkins, director of Duke Law School's Center for the Study of the Public Domain. The release is unprecedented, and its impact on culture and creativity could be huge. We have never seen such a mass entry into the public domain in the digital age. The last one -- in 1998, when 1922 slipped its copyright bond -- predated Google. "We have shortchanged a generation," said Brewster Kahle, founder of the Internet Archive. "The 20th century is largely missing from the internet."

We can blame Mickey Mouse for the long wait. In 1998, Disney was one of the loudest in a choir of corporate voices advocating for longer copyright protections. At the time, all works published before January 1, 1978, were entitled to copyright protection for 75 years; all author's works published on or after that date were under copyright for the lifetime of the creator, plus 50 years. Steamboat Willie, featuring Mickey Mouse's first appearance on screen, in 1928, was set to enter the public domain in 2004. At the urging of Disney and others, Congress passed the Sonny Bono Copyright Term Extension Act, named for the late singer, songwriter and California representative, adding 20 years to the copyright term. Mickey would be protected until 2024 -- and no copyrighted work would enter the public domain again until 2019, creating a bizarre 20-year hiatus between the release of works from 1922 and those from 1923.

Thirty years ago, the ocean waters surrounding British islands in the South Atlantic were near-pristine. But plastic waste has increased a hundredfold since then, and is ten times greater than it was a decade ago. From a report: The islands of the British Overseas Territories in the South Atlantic, including St. Helena, East Falkland, and Ascension Island, are so tiny and remote that most people don't even realize they exist. For centuries, that kept them relative clean and pristine, but in recent decades discarded straws, fishing nets, and millions of bits of degraded plastic have begun washing up on their shores. Now, reports Marlene Cimons at Nexus Media, that pollution is getting even worse. A new study in the journal Current Biology shows that plastic trash on the beaches and in the ocean has increased tenfold in the just the last decade and a hundredfold over the last three decades.

During four research cruises between 2013 and 2018, researchers from the British Antarctic Survey and nine other organizations aboard the RMS James Clark Ross sought to quantify the plastic around the islands. The crew took samples of marine debris from the water's surface, the water column, the seabed and the beaches. They also investigated plastic ingestion in 2,243 animals comprised of 26 different species ranging across the marine food web from plankton to apex predators, like seabirds; all were found to consume plastic at high rates. What they found was plastic, and lots of it. About 90 percent of all the contaminants they analyzed were made of plastic, which abundant in the ocean, on the beach and inside the animals.

A new study published by the Entomological Society of America found that bees stop flying when the moon obstructs the sun during a total solar eclipse. "Using tiny microphones suspended among flowers, the team recorded the buzzing of the bees through all stages of the eclipse," reports Smithsonian Magazine. "The bees were active and noisy right up to the last moments before totality, the part of a total solar eclipse when the moon blocks all direct sunlight, and a night-like darkness settles over the land. As totality hit, the bees went totally silent in unison." From the report: The clear drop from buzzing to silence was the most striking change during the eclipse, but additional, smaller changes in the bees' buzzing could give the researchers clues about how the insects responded. As ecologist Candace Galen of the University of Missouri notes, the bees' buzzes lasted longer as it gradually got darker approaching totality. Increased buzz length suggests the bees started flying more slowly, they were taking longer flights, or some combination of both.

"The way I think about it is, if you're driving on a road and it gets foggy, you slow down," explains Galen. When there is less visibility, slowing down helps you process information and maintain situational awareness -- and like the bees did during totality, if there's absolutely zero visibility, you should probably pull over. Adjusting speed to acclimate one's senses to an environment that suddenly shifts is a common behavior in many animals, and it's been observed in bees when they fly before sunrise or sunset.

An anonymous reader quotes a report from Smithsonian: Australian researchers may have found a way to detect landslides as far as two weeks in advance, giving residents time to evacuate and engineers the opportunity to shore up slopes. Using AI and applied mathematics they've developed a software that can identify the subtle signs of an impending slide, signs that would be invisible to the naked eye. "Right now, a lot of the predictions [about where landslides will happen] are based on someone's gut instinct on the location," says Antoinette Tordesillas, a professor at the School of Mathematics and Statistics at the University of Melbourne, who co-led the research. "We don't rely on gut instinct. We want to develop an objective method here." To develop the software, Tordesillas and her team used radar data from mining companies, which produce extremely detailed information of the surface movement of slopes. The team took the data and looked for patterns, eventually figuring out which networks of movements indicated unstable locations. They also used data from a landslide-prone Italian volcano to help develop the algorithm. The software can also incorporate data about other landslide risk factors, like rainfall and erosion, making the targeting even more precise. The data used for monitoring can come from radar based on the ground, on satellites or even in drones.

An anonymous reader quotes a report from Smithsonian: According to new research, rising carbon dioxide levels will sap some of the nutrients from our crops and lead to dietary deficiencies in millions of humans. In 2014, field trials of common food crops including wheat, rice, corn and soybeans showed that as the amount of carbon dioxide in the atmosphere increased, the levels of iron, zinc and protein decreased in the dietary staples by 3 to 17 percent. While the decrease in a few nutrients may not seem important in food secure countries, it could have a big impact in poorer nations.

In the new study published in the journal Nature Climate Change, researchers calculated the impact of declining nutrients on human health. According to a press release, the team looked at the impact of rising CO2 on 225 different types of food. Based on population estimates for 2050 and an expected rise of carbon dioxide from about 400 parts per million today to 550 ppm by mid-century, the team found that the nutrient deficiencies of those already suffering will worsen, and 175 million more people could join the 1.2 billion who are zinc deficient and 122 million people would be added to the 622 million who don't receive enough protein. About 1.4 billion women of childbearing age and children under 5 could see their iron intake drop by about 4 percent.

According to two complementary studies, sperm change their cargo as they travel the reproductive tract, which can have consequences on the viability of future offspring. Smithsonian reports: The legacy of a dad's behavior can even live on in his child if his epigenetic elements enter an embryo. For instance, mice born to fathers that experience stress can inherit the behavioral consequences of traumatic memories. Additionally, mouse dads with less-than-desirable diets can pass a wonky metabolism onto their kids. Upasna Sharma and Colin Conine, both working under Oliver Rando, a professor of biochemistry at the University of Massachusetts Medical School, were some of the researchers to report such findings in 2016. In their work, Sharma and Conine noted that, in mice, while immature testicular sperm contain DNA identical to that of mature sperm, immature sperm relay different epigenetic information. It turns out that sperm small RNAs undergo post-testes turnover, picking up intel on the father's physical health (or lack thereof) after they're manufactured, but before they exit the body. However, the exact pit stop at which these additional small RNAs hitch a ride remained unknown.

To solve the mystery, Sharma, who led the first of the two new studies, decided to track the composition of small RNAs within mouse sperm as they fled the testes and cruised through the epididymis. She and her colleagues isolated sperm of several different ages from mice, including those about to emerge from the testes, those entering the early part of the epididymis and those in the late part of the epididymis. Sharma was surprised to find that many small RNAs seemed to be discarded or destroyed upon entering the early epididymis; then, the newly vacated sperm reacquired epigenetic intel that reflected the father's state of being, boasting a full set by the time they left the late epididymis. There was only one possible source for the small RNA reacquisition: the cells of the epididymis -- which meant that cells outside of the sperm were transmitting information into future generations. [...] Colin Conine, who led the second of the two new studies, next tested if using immature sperm would have noticeable effects on the offspring of mice. He and his colleagues extracted sperm from the testes, early epididymis and late epididymis and injected them into eggs. All three types of sperm were able to fertilize eggs. However, when Conine transferred the resulting embryos into mouse surrogates, none derived from early epididymal sperm -- the intermediate stage devoid of most small RNAs -- implanted in the uterus. The least and most mature sperm of the bunch were winners -- but somehow, those in the middle were burning out, even though all their genes were intact. The only other explanation was that the defect was temporary. If this was the case, then perhaps, if fed the right small RNAs, the early epididymal sperm could be rescued.

An anonymous reader quotes a report from Smithsonian: The science of longevity is surprisingly controversial, mainly because there are so few people of extreme old age -- defined at 110 years or older -- around to study. So researchers look to statistics to try and figure out how long people can live. [Ben Guarino reports via The Washington Post] that in 1825, actuary Benjamin Gompertz put forth the idea that the odds of dying grow exponentially as we age. Further research bears that out. Between the age of 30 and 80, the odds of dying double every 8 years. What happens after that, however, is not completely figured out. According to a controversial study released in 2016, which analyzed data from 40 different countries, the average person could make it to 115 with the right genes and interventions, and a few genetic superstars would be able to make it to 125. But that was it, they argued. There was a wall of mortality that medicine and positive thinking simply cannot overcome.

But not everyone is convinced by that data. That's why for the new paper in the journal Science, researchers looked at the lifespans of 3,836 people in Italy who reached the age of 105 or older between 2009 and 2015, with their ages verified by birth certificates. What they found is that the Gompertz law goes a little haywire around the century mark. According to a press release, a 90 year old woman has a 15 percent chance of dying in the next year, and an estimated six years left to live. At age 95, the chance of dying per year jumps to 24 percent. At the age of 105, the chance of dying makes another leap to 50 percent. But then, surprisingly, it levels off, even past 110. In other words, at least statistically, each year some lucky person could flip the coin of life, and if it comes up heads every time, they could live beyond 115 or 125.

A creature as majestic as a whale, you might think, should have no owner. Yet it turns out that certain snippets of the DNA that makes a sperm whale a sperm whale are actually the subjects of patents -- meaning that private entities have exclusive rights to their use for research and development. From a report: The same goes for countless other marine species. And new research shows that a single German chemical company owns 47 percent of patented marine gene sequences. A just-published paper in Science Advances finds that 862 separate species of marine life have genetic patents associated with them. "It's everything from microorganisms to fish species," says lead author Robert Blasiak, a conservation researcher at the University of Stockholm who was shocked to find out how many genetic sequences in the ocean were patented. "Even iconic species" -- like plankton, manta rays, and yes, sperm whales. Of some 13,000 genetic sequences targeted by patents, nearly half are the intellectual property of a company called Baden Aniline and Soda Factory (BASF).

An anonymous reader writes: The Netherlands' first functional 3D-printed home will be ready to welcome occupants as early as next year. According to The Guardian's Daniel Boffey, the one-story, two-bedroom house is the first and smallest of five 3D-printed concrete homes set for construction in the Dutch city of Eindhoven. The five-year initiative, known as Project Milestone, aims to combat the country's shortage of skilled bricklayers and revitalize the architectural industry. Project Milestone emerged as a collaboration between the Eindhoven University of Technology, a global leader in 3D printing, and Dutch construction company Van Wijnen. Real estate manager Vesteda, materials company Saint Gobain-Weber Beamix and engineering firm Witteveen+Bos also contributed to the project.

Scientists from the Southwest Research Institute suggest Pluto may be a comet, as opposed to a planet or dwarf planet. According to a study published in the journal Icarus, Pluto could be made up of billions of comets all mashed together. Smithsonian reports: Scientists had long believed the dwarf planet Pluto was formed the way planets come to be: they start as swirling dust that's gradually pulled together by gravity. But with the realization that Pluto was a Kuiper belt dwarf planet, researchers began speculating about the origins of the icy world. The researchers turned to Sputnik Planitia -- the western lobe of the massive heart-shaped icy expanse stamped on Pluto's side -- for the task. As Christopher Glein, lead author of the paper and researcher at the Southwest Research Institute, explains to [Popular Science editor Neel V. Patel], the researchers used the data from New Horizons on this icy expanse to estimate the amount of nitrogen on Pluto and the amount that's escaped from its atmosphere.

Glein explains the conclusions in a statement: "We found an intriguing consistency between the estimated amount of nitrogen inside the [Sputnik Planitia] glacier and the amount that would be expected if Pluto was formed by the agglomeration of roughly a billion comets or other Kuiper Belt objects similar in chemical composition to 67P, the comet explored by Rosetta." The report goes on to mention a few caveats. "For one, researchers aren't sure that comet 67P has an average comet composition," reports Smithsonian. "For another, New Horizons only captured information about Pluto at a specific point in time, which means nitrogen rates could have changed over the last billions of years. [T]here's also still the possibility Pluto formed from cold ices with a chemical composition to that of the sun."

The Washington Post: The Atlantic Ocean circulation that carries warmth into the Northern Hemisphere's high latitudes is slowing down because of climate change, a team of scientists asserted Wednesday, suggesting one of the most feared consequences is already coming to pass (Editor's note: the link may be paywalled; alternative source). The Atlantic meridional overturning circulation has declined in strength by 15 percent since the mid-20th century to a "new record low," the scientists conclude in a peer-reviewed study published in the journal Nature. That's a decrease of 3 million cubic meters of water per second, the equivalent of nearly 15 Amazon rivers.

The AMOC brings warm water from the equator up toward the Atlantic's northern reaches and cold water back down through the deep ocean. The current is partly why Western Europe enjoys temperate weather, and meteorologists are linking changes in North Atlantic Ocean temperatures to recent summer heat waves. The circulation is also critical for fisheries off the U.S. Atlantic coast, a key part of New England's economy that have seen changes in recent years, with the cod fishery collapsing as lobster populations have boomed off the Maine coast.

New Scientist: The most recognisable scientist of our age, Hawking holds an iconic status. [...] He was routinely consulted for oracular pronouncements on everything from time travel and alien life to Middle Eastern politics and nefarious robots. He had an endearing sense of humour and a daredevil attitude -- relatable human traits that, combined with his seemingly superhuman mind, made Hawking eminently marketable.

But his cultural status -- amplified by his disability and the media storm it invoked -- often overshadowed his scientific legacy. That's a shame for the man who discovered what might prove to be the key clue to the theory of everything, advanced our understanding of space and time, helped shape the course of physics for the last four decades and whose insight continues to drive progress in fundamental physics today. The New York Times: 1970 Dr. Hawking shows that the area of a black hole's event horizon -- a spherical surface marking the point of no return -- can only increase, never decrease, as stuff falls into a black hole or it collides and merges with other black holes.
1971 He suggests that mini black holes much smaller than stars created in the Big Bang could be peppering the universe.
1974 He shocks his colleagues and the world by showing that black holes will leak and explode when quantum effects -- the weird laws that describe subatomic behavior -- are taken into account.
1976 Dr. Hawking says exploding black holes add randomness and unpredictability to the universe, forever erasing information about what might have fallen into a black hole.

Quantum physicists object, saying the universe can't forget, initiating a 40-year argument about the fate of information. Dr. Hawking concedes in 2004, but does not say how information is preserved in a black hole, and the argument continues to this day.
1982 Using a mathematical conceit called imaginary time, Dr. Hawking and James Hartle, a theoretical physicist at the University of California, Santa Barbara, propose a model of a self-contained universe that has no boundary in space or time, and thus no place or time when the laws of physics break down.

Researchers have cataloged close to 7,000 distinct human languages on Earth, per Linguistic Society of America's latest count. That may seem like a pretty exhaustive list, but it hasn't stopped anthropologists and linguists from continuing to encounter new languages, like one recently discovered in a village in the northern part of the Malay Peninsula. From a report: According to a press release, researchers from Lund University in Sweden discovered the language during a project called Tongues of the Semang. The documentation effort in villages of the ethnic Semang people was intended to collect data on their languages, which belong to an Austoasiatic language family called Aslian. While researchers were studying a language called Jahai in one village, they came to understand that not everyone there was speaking it. "We realized that a large part of the village spoke a different language. They used words, phonemes and grammatical structures that are not used in Jahai," says Joanne Yager, lead author of the study, which was published in the journal Linguist Typology. "Some of these words suggested a link with other Aslian languages spoken far away in other parts of the Malay Peninsula."

Tens of millions of years after it disappeared under the waters of the Pacific Ocean, scientists have completed the first explorations of what some scientists are calling a hidden continent. From a report: During a two-month ocean voyage this summer, a team of more than 30 scientists from 12 countries explored the submerged landmass of Zealandia on an advanced research vessel and collected samples from the seabed. Scientists were able to drill into the ocean floor at depths of more than 4,000 feet, collecting more than 8,000 feet of sediment cores that provides a window into 70 million years of geologic history, reports Georgie Burgess for ABC News. More than 8,000 fossils from hundreds of species were also collected in the drilling, giving scientists a glimpse at terrestrial life that lived tens of millions of years ago in the area. "The discovery of microscopic shells of organisms that lived in warm shallow seas, and of spores and pollen from land plants, reveal that the geography and climate of Zealandia were dramatically different in the past," expedition leader Gerald Dickens said in a statement. While more than 90 percent of Zealandia is now submerged under more than a kilometer (two-thirds of a mile) of water, when it was above the surface, it likely provided a path that many land animals and plants could have used to spread across the South Pacific, notes Naaman Zhou of the Guardian.

From a report: To study life on Earth, you need a system. Ours is Linnaean taxonomy, the model started by Swedish biologist Carl Linnaeus in 1735. Linnaeus's two-part species names, often Latin-based, consist of both a genus name and a species name, i.e. Homo sapiens. Like a library's Dewey Decimal system for books, this biological classification system has allowed scientists around the world to study organisms without confusion or overlap for nearly 300 years. But, like any library, taxonomy is only as good as its librarians -- and now a few rogue taxonomists are threatening to expose the flaws within the system. Taxonomic vandals, as they're referred to within the field, are those who name scores of new taxa without presenting sufficient evidence for their finds. Like plagiarists trying to pass off others' work as their own, these glory-seeking scientists use others' original research in order to justify their so-called "discoveries." "It's unethical name creation based on other people's work," says Mark Scherz, a herpetologist who recently named a new species of fish-scaled gecko. "It's that lack of ethical sensibility that creates that problem." The goal of taxonomic vandalism is often self-aggrandizement. Even in such an unglamorous field, there is prestige and reward -- and with them, the temptation to misbehave. "If you name a new species, there's some notoriety to it," Thomson says. "You get these people that decide that they just want to name everything, so they can go down in history as having named hundreds and hundreds of species." The problem may be getting worse, thanks to the advent of online publishing and loopholes in the species naming code. With vandals at large, some researchers are less inclined to publish or present their work publicly for fear of being scooped, taxonomists told me. "Now there's a hesitation to present our data publically, and that's how scientists communicate," Thomson says. "The problem that causes is that you don't know who is working on what, and then the scientists start stepping on each other's toes."

Saint Catherine's Monastery, a sacred Christian site nestled in the shadow of Mount Sinai, is home to one of the world's oldest continuously used libraries. Thousands of manuscripts and books are kept there -- some of which contain hidden treasures. An anonymous reader shares a report: Now, a team of researchers is using new technology to uncover texts that were erased and written over by the monks who lived and worked at the monastery. Many of these original texts were written in languages well known to researchers -- Latin, Greek, Arabic -- but others were inscribed in long-lost languages that are rarely seen in the historical record. Manuscripts with multiple layers of writing are known as palimpsests, and there are about 130 of them at St. Catherine's Monastery, according to the website of the Early Manuscript Electronic Library, which has been leading the initiative to uncover the original texts. With the rise of Islam in the 7th century, Christian sites in the Sinai Desert began to disappear, and Saint Catherine's found itself in relative isolation. Monks turned to reusing older parchments when supplies at the monastery ran scarce. To uncover the palimpsests' secret texts, researchers photographed thousands of pages multiple times, illuminating each page with different-colored lights. They also photographed the pages with light shining onto them from behind, or from an oblique angle, which helped "highlight tiny bumps and depressions in the surface," Gray writes. They then fed the information into a computer algorithm, which is able to distinguish the more recent texts from the originals.

An anonymous reader quotes Smithsonsian: It was with minimal expectations that, on August 3, 1977, Tandy Corporation teamed up with Radio Shack to release the TRS-80, one of the first personal computers available to consumer markets. While Don French -- a buyer for the Tandy Radio Shack consumer electronic chain -- had convinced some Tandy executives of the need to release a personal computer, most felt it was unlikely to gross substantial profits. This bulky item with complex operating procedures would never sell, they thought, more than 1,000 units in its first month... As it turned out, the TRS-80 surpassed even the most cautious sales estimates by tenfold within its first month on the market; the burgeoning prospects of a new era in personal electronics and computing could no longer be denied.
It had no hard drive and four kilobytes of memory, according to the article. Radio Shack's $600 PC was preceded by the MITS Altair, as well as PCs from both Apple and IBM, but "the TRS-80 was one of the first products that came fully assembled and ready to use, bridging the gap in accessibility between hobbyists -- who took interest in the actual building of the computer -- and the average American consumer, who wanted to know what this new, cutting-edge technology had in store for them."

Does this bring back any memories for anyone?

The world's oceans are littered with trillions of pieces of plastic -- bottles, bags, toys, fishing nets and more, mostly in tiny particles -- and now this seaborne junk is making its way into the Arctic. From a report: The plastic was discovered by an international team of researchers who circumnavigated the Arctic on a five-month journey aboard the research vessel Tara in 2013. They sampled the ocean water along the way, looking at plastic pollution. And though the plastic concentrations were overall low, they located a specific region located north of the Greenland and the Barents seas with unusually high concentrations. They published their results in the journal Science Advances this week. It seems that the plastic is riding up to the pole with the Thermohaline Circulation, a "conveyor" belt ocean current that transports water from the lower latitudes of the Atlantic Ocean toward the poles. "[A]nd the Greenland and the Barents Seas act as a dead-end for this poleward conveyor belt," Andres Cozar Cabanas, lead author of the study and researcher at the University of Cadiz, Spain, says in a press release.

An anonymous reader shares a report: It sounds like an argument scientists might have during a night of drinking: Which creature has the most interesting genome in the world? But the question is more than a passing musing. San Francisco biotech company Pacific Biosciences held a public competition to determine which critter should receive the honor. The winner: Sandy Maliki, an Australian desert dingo. The company will now sequence the dingo's genome to help researchers study animal domestication. Sandy beat out four other interesting finalists in the competition, receiving 41 percent of the public votes, which were cast from around the world. This is the fourth year the company has sponsored the competition. The company invites researchers to send in grant proposals explaining why the interesting plants and animals they study should be sequenced. Then a committee of scientists whittles the entries down to five finalists for the final public vote.

From an article on the Smithsonian magazine: On this day in 1961, Yuri Gagarin became the first person in space. And given the risks inherent to early spaceflight, he certainly deserves his place in history. But what about the man who designed the rocket that got Gagarin there? His name was Sergei Korolev, and his influence on the Soviet space program stretched much farther than Gagarin's 108 minutes of fame -- the time it took to make a single orbit of Earth. The flight of Vostok 1, Gagarin's craft, "was a defining moment of the 20th century and opened up the prospect of interplanetary travel for our species," writes Robin McKie for The Guardian. For Gagarin, it was the moment that made him a famous figurehead for the Soviet Union. As Gagarin toured the globe, the space program's chief designer remained at home and unknown. That Sergei Korolev ran the Soviet Union's rocket program wasn't revealed until after his death. "Gagarin became the face of Soviet space supremacy," McKie writes, "while Korolev was the brains. The pair made a potent team and their success brought fame to one and immense power to the other. Neither lived long enough to enjoy those rewards, however."

New submitter omaha393 writes: A public engagement campaign is underway in the hopes of convincing Burkina Faso residents to allow the release of genetically modified mosquitoes to combat deadly mosquito-borne pathogens. GM mosquitoes rely on a technology called "gene drives." Different gene drives offer different solutions, typically leading to subsequent broods being sterile, predominantly male, resistant to infection or nonviable due to toxic traits. Researchers in this case are only in the preliminary stages of releasing sterile males but hope to begin wider releases of GM mosquitoes in about 6 years.

Burkina Faso is not the only country to pursue GM mosquitoes in efforts to prevent disease. Brazil has become a testing ground for wide release, and last fall voters in Florida Keys approved measures to begin releasing GM mosquitoes to fight the spread of Zika. Both the WHO and the U.S. FDA have approved the technique, but skeptics are critical of the method.

Clint Perry, a biologist who studies the evolution of cognition in insects at Queen Mary University of London, and his colleagues have released the results of a creative new experiment in which they essentially taught bumblebees how to play "bee soccer." "The insects' ability to grasp this novel task is a big score for insect intelligence, demonstrating that they're even more complex thinkers than we thought," reports Smithsonian. From the report: For the study, published in the February 23 issue of Science, researchers gave a group of bees a novel goal (literally): to move a ball about half their size into a designated target area. The idea was to present them with a task that they would never have encountered in nature. Not only did the bees succeed at this challenge -- earning them a sugary treat -- but they astonished researchers by figuring out how to meet their new goal in several different ways. Some bees succeeded at getting their ball into the goal with no demonstration at all, or by first watching the ball move on its own. But the ones that watched other bees successfully complete the game learned to play more quickly and easily. Most impressively, the insects didn't simply copy each other -- they watched their companions do it, then figured out on their own how to accomplish the task even more efficiently using their own techniques. The results show that bees can master complex, social behaviors without any prior experience -- which could be a boon in a world where they face vast ecological changes and pressures.

On Monday at 7:47 A.M. EST, an asteroid thought to be between 36 and 111 feet wide passed roughly 120,000 miles from Earth -- and astronomers didn't spot it until Saturday. Smithsonian reports: According to astronomer Eric Edelman at the Slooh Observatory, 2017 AG13 is an Aten asteroid, or a space rock with an orbital distance from the sun similar to that of Earth. AG13 also has a particularly elliptical orbit, which means that as it circles the sun it also crosses through the orbits of both Venus and Earth. Lucky for us, 2017 AG13 wasn't a planet killer; according to Wall, the asteroid was in the size range of the space rock that exploded in Earth's atmosphere over Chelyabinsk, Russia, in February, 2013. According to Deborah Byrd at EarthSky, that meteor exploded 12 miles in the atmosphere, releasing 30 times the energy of the Hiroshima nuclear bomb. Not only did it break windows in six cities, it also sent 1,500 people to the hospital. That meteor also came out of the blue, and researchers are still trying to figure out its orbit and track down its origins. While 2017 AG13 would have caused minor damage if it hit Earth, the close call highlights the dangers of asteroids.

bsharma writes: Scientists have formally announced their reconstruction of the Ein Gedi Scroll, the most ancient Hebrew scroll since the Dead Sea Scrolls. This was done by CAT scanning the burnt scrolls and virtually reconstructing the layers of scrolls with ink blobs on them. National Geographic reports: "For decades, the Israel Antiquities Authority guarded the document, known as the Ein Gedi Scroll, careful not to open it for fear that the brittle text would shatter to pieces. But last year, scientists announced that they had scanned, virtually unrolled, and translated the scroll's hidden verses -- a feat now formally described in the scientific literature. Based on preliminary scans, [Brent Seales of the University of Kentucky, who specialized in digitally reconstructing damaged texts,] and his colleagues announced in 2015 that the Ein Gedi Scroll was a biblical text from the sixth century A.D. containing a column of text from the book of Leviticus. But the full CT scan results, published on Wednesday in Science Advances, tell a deeper story. Further analysis revealed an extra column of text, ultimately fleshing out the first two chapters of Leviticus -- ironically, a book that begins with God's instructions for burnt offerings. What's more, radiocarbon dating of the scroll suggests that it may be between 1,700 and 1,800 years old, at least 200 years older than previously thought. In fact, the scroll's distinctive handwriting hearkens back to the first or second century A.D., some five centuries earlier than the date ascribed to the scroll last year." University of Cambridge lecturer James Aitken told Smithsonian's Devin Powell in 2015: "There's little of surprise in finding a Leviticus scroll. We probably have many more copies of it than any other book, as its Hebrew style is so simple and repetitive that it was used for children's writing exercises."

Alex Pearlman, reporting for Motherboard: As the biotech revolution accelerates globally, the U.S. could be getting left behind on key technological advances: namely, human genetic modification. A Congressional ban on human germline modification has "drawn new lines in the sand" on gene editing legislation, argues a paper published today in Science by Harvard law and bioethics professor I. Glenn Cohen and leading biologist Eli Adashi of Brown University. They say that without a course correction, "the United States is ceding its leadership in this arena to other nations." Germline gene modification is the act of making heritable changes to early stage human embryos or sex cells that can be passed down to the next generation, and it will be banned in the US. This is different from somatic gene editing, which is editing cells of humans that have already been born. The ban, added by the House of Representatives as a rider to the fiscal year 2016 budget, could have far-reaching implications if it continues to be annually renewed, according to the authors. It "undermines ongoing conversations on the possibility of human germline modification" and also affects "ongoing efforts by the FDA [Food and Drug Administration] to review the prevention of mitochondrial DNA diseases," including some kinds of hearing and vision impairments, among other serious illnesses that tend to develop in young children.

mdsolar writes with this story from Smithsonian magazine about how building a national transmission network could lead to a gigantic reduction in carbon emissions. From the story: "The United States could lower carbon emissions from electricity generation by as much as 78 percent without having to develop any new technologies or use costly batteries, a new study suggests. There's a catch, though. The country would have to build a new national transmission network so that states could share energy. 'Our idea was if we had a national 'interstate highway for electrons' we could move the power around as it was needed, and we could put the wind and solar plants in the very best places,' says study co-author Alexander MacDonald, who recently retired as director of NOAA's Earth System Research Laboratory in Boulder, Colorado."

HughPickens.com writes: Violence has always been part of human behavior, but the origins of war are hotly debated. Some experts see it as deeply rooted in evolution, pointing to violent confrontations among groups of chimpanzees as clues to an ancestral predilection while others emphasize the influence of complex and hierarchical human societies, and agricultural surpluses to be raided. Now James Gorman writes in the NY Times that scientists have discovered a site in Africa dated about 10,000 years ago where a group of hunter-gatherers attacked and slaughtered another, leaving the dead with crushed skulls, embedded arrow or spear points, and other devastating wound. It's not clear that anyone was spared at the Nataruk massacre. Of the 27 individuals found, eight were male and eight female, with five adults of unknown gender. The site also contained the partial remains of six children. Twelve of the skeletons were in a relatively complete state, and ten of those showed very clear evidence that they had met a violent end. In the paper, the researchers describe "extreme blunt-force trauma to crania and cheekbones, broken hands, knees and ribs, arrow lesions to the neck, and stone projectile tips lodged in the skull and thorax of two men." Four of them, including a late-term pregnant woman, appear to have had their hands bound. "These human remains record the intentional killing of a small band of foragers with no deliberate burial, and provide unique evidence that warfare was part of the repertoire of inter-group relations among some prehistoric hunter-gatherers," says Dr Marta Mirazon.

The killers carried weapons they wouldn't have used for hunting and fishing, including clubs of various sizes and a combination of close-proximity weapons like knives and distance weapons, including the arrow projectiles she calls a hallmark of inter-group conflict. " This suggests premeditation and planning," says Mirazon Lahr. Other, isolated examples of period violence have previously been found in the area, and those featured projectiles crafted of obsidian, which is rare in the area but also seen in the Nataruk wounds. This suggests that the attackers may have been from another area, and that multiple attacks were likely a feature of life at the time. "This implies that the resources the people of Nataruk had at the time were valuable and worth fighting for, whether it was water, dried meat or fish, gathered nuts or indeed women and children. This shows that two of the conditions associated with warfare among settled societies—control of territory and resources—were probably the same for these hunter-gatherers, and that we have underestimated their role in prehistory."

An anonymous reader writes: Modern storage methods are designed with longevity in mind. But we haven't always had the scientific knowledge or the foresight to do so. From the late 60s to the late 80s, much of the world's cultural history was recorded on magnetic tapes. Several decades on, those tapes are disintegrating, and we're faced with the permanent loss of that data. "The Cultural Heritage Index estimates that there are 46 million magnetic tapes in museums and archives in the U.S. alone—and about 40 percent of them are of unknown quality. (The remaining 60 percent are known to be either already disintegrated or in good enough condition to be played.)" Fortunately, researchers have worked out a method to determine which copies are recoverable. They "combined a laptop-sized infrared spectrometer with an algorithm that uses multivariate statistics to pick up patterns of all the absorption peaks." Here's the abstract from their research paper. "As the tapes go through the breakdown reaction, the chemical changes give off tiny signals in the form of compounds, which can be seen with infrared light—and when the patterns of reactions are analyzed with the model, it can predict which tapes are playable."

ClockEndGooner writes: A study conducted by the Netherlands Organization for Applied Scientific Research found that low frequency and long wavelength jet engine droning noise was significantly reduced in the fall after farmers plowed their fields near Amsterdam's Schiphol Airport. The remaining furrows "had multiple ridges to absorb the sound waves, deflected the sound and muted the noise." This led to the development of the Buitenschot Land Art Park, a buffer park featuring "land art" that has significantly reduced aircraft noise without requiring cuts in the number of allowed flights in and out of the airport. The land art park has also provided neighbors with additional recreational paths and sports fields in the same space.

Austin has a strong western heritage and more country and western music than you can shake a fiddle bow at. So when Timothy came back from SXSW with video clips from two home automation companies with different approaches to this question: "How can you work with a whole bunch of lights and thermostats and other IoT home automation pieces that all have different OSes and control APIs?" we obviously had to call the resulting video 'Dueling Home Automation Systems.'

The two companies shown in this video are called WigWag and Yonomi. WigWag sells you a "Relay," which they say "is a powerful mini computer that gives you control of your home's smart devices." The minimum pre-order buy-in for WigWag seems to be a $149 WigWag Relay. Their 'products' page his page shows the Relay -- and many other gadgets and kits that could easily run your total tab up to $1000 or more. Yonomi, on the other hand, "resides on your phone and in the Cloud. No need for a hub, controller box or other additional hardware. Yonomi magically finds and enhances your existing connected devices allowing them to interact with one another in ways never before possible."

Yonomi may start with a free Android app (iOS coming soon), but you still need to buy lights, speakers, thermostats, and other things that are Internet-aware, so you're not going to save much (if anything) over buying a WigWag relay and the rest of what you need to create your own, private Internet of Things. And what about good old X10 and other home control systems? They're still out there, still doing their thing in millions of homes even if they aren't getting all the IoT buzz. In any case, it's nice to see new home automation alternatives coming down the pike, even if their cloudness may make them easier to hack than an old-fashioned appliance like this coffeemaker.

Last week you had a chance to ask Saturday Morning Breakfast Cereal (SMBC) creator and monocle enthusiast Zach Weiner about his comics, reading classy, and his other projects. Below you'll find his answers to your questions. How did it start?
by Flavianoep

Expanding my question, what inspired you to write your webcomic?

Weiner: SMBC really started in like 1998? I had a geocities site called Saturday Morning Breakfast Cereal, where I posted essays and comics and such. It was purely for amusement, with no plan to make money.

Later it morphed into just comics, and people seemed to like it. Later still, I was working a shit job in Hollywood and desperately wanted to escape. So, I focused on comics, and a few years later I was able to quit my job!



Sacred cows?
by eldavojohn

Have there been any times you feared you went too far with your humor? If not, when have you received the most mail asserting that you did?

Weiner: Definitely, yeah. I actually once finished a comic (I forget the joke, but the image was very old people having sex) and then shelved it for being too crude. Then later I was out of ideas and needed an update.

I don’t actually get a lot of hatemail. Then one time I was blindsided was a comic where I had some fratboys finding out a frat brother was dead, and then drawing dicks on his face. Apparently that was a bit upsetting for some people.



Jokes you didn't tell
by gman003

You often tell jokes that rely on fairly advanced math, science or economics. Have there been any jokes you scrapped because you thought they were *too* advanced for your audience?

Weiner: Well, as a general rule, jokes of that sort aren’t reallllly funny? Like, they’re association-funny, but not actually clever. There are exceptions, but not many. I don’t think I’ve ever held back a good joke just because it was niche.

In fact, I could argue the Internet favors jokes like that, at least in the short term. Like, I once did a joke about using TI-83s as a stable reserve currency. Probably was not liked by most of my audience, but the people who DID like it shared it a lot. Or, similarly, I did one about the Chairman of the Fed dressing up as a ghost and haunting banks to boost consumption. Niche joke, but it got lots of shares.



Gender and skin color
by gsliepen

Dear Zach, I noticed that your comics feature a remarkable balance in gender and skin color of the people you draw. There are also many same-gender couples. How do you do this? Do you decide yourself for each comic, or do you roll some dice? Do you randomize other things this way as well, like glasses and clothes? By the way, I noticed that you maintain a list of things you cannot draw. But don't worry, you're way better than that Randall guy who can only draw black&white stick figures.

Weiner: What’s really weird is (possibly because my audience is a bunch of dorks) is that tons of people assume I have an algorithm or some random mechanism. The truth is I just don’t write gender/color/etc. into the script unless it’s relevant to the joke. Then, when I’m drawing I pick semi-randomly.

You don’t want to be completely random, because you could get in trouble. Like, if I’m drawing someone committing financial crime, I don’t want my random throw to be Jewish. In general, I try to avoid stereotypes. So, for instance, if there’s only one irrational character in the strip, I try to make it a dude. Also, when someone has to be the jerk in the strip, I generally draw a redhead, so I’m really drawing myself as the asshole?

Randall who? Rand Paul?



The Rise of Joke Theft on the Internet
by eldavojohn

I'm not talking about your humorous Sarah Silverman satire video but the actual people who misappropriate a joke for their own. I've seen it on Facebook where someone reads a joke on Reddit or XKCD or SMBC and just rehashes it as their own idea in a post knowing that no one else out there could possibly be wasting their time on something like SMBC. Do you see this as frequently as I do? In all honesty does this bother you or merely flatter you? Is it just a natural unavoidable quality of memes or do you think it's more sinister?

Weiner: Here’s the thing. In 1990, when I was 8, I used to redraw other people’s comics and show them off. But who gives a shit, because it’s an 8 year old. Now, it’s all public. I think the real danger is NOT that people like me get ripped off - it’s that young artists aren’t even allowed to imitate. Imitation is how you figure out what you like!

That said, it’s easy for me to not care, since I’m making a comfortable living. But, in general, I think with “joke theft” we should err on the side of tolerance. That said, when sites like 9gag take my stuff and watermark it, yeah, that pisses me off. But, there’s nothing you can really do.



Ren & Stimpy
by SupahVee

I see a fair bit of other influences in your comics, with Ren & Stimpy references seeming to show up here and there. What other comic have played a role in your work, and is there some bad experience in early childhood that clearly left you so scarred from Ren & Stimpy?

Weiner: Really? I definitely watched as a kid, but I’m curious what you see as Ren & Stimpy references! I’m at least not doing it on purpose. My early big comic influences were Scott Adams, Glen Baxter, and the comic The Parking Lot is Full. Since then, I’ve diverged a lot. These days I try to take more influence from books and concepts than other cartoonists. But, many comics continue to impress - xkcd, Hark a Vagrant, Buttersafe, Oglaf. Recently I’ve really enjoyed Whomp!



Intellectual Sources
by Gestahl

With respect to your "philosophical thought experiment" comics, how many of your comics are based in topics/ideas you learned before the end of your formal education, how many are based on things you have encountered in your "continuing education" (whether based on life experience, or just what you are currently reading about), and how many are "novel" intuition pumps?

Weiner: Most I’ve learned after. But, I was a pretty lousy college student. I try to read 3-5 books a week, and make time for deep reading as well. It’s harder now that I have a kid, but the kid provides some insight too, I suppose.

I don’t know how much is new. That said, I was very pleased to find out about Nozick’s Utility Monster AFTER I’d done a comic describing that exact idea! I was 40 years too late, but it’s neat to know that I came up with something a smarter guy came up with.



The Mrs. and the extended comic
by Anonymous Coward

How does your wife feel being portrayed in the comic?

Weiner: My wife likes the spotlight more than me! She’s actually doing some public science lecturing in the near future, if anyone’s interested.

So, I think she even enjoy the insulting ones (i.e. all of them).



Zach Weiner is awesome
by Jax Omen

I love Zach, met him at a comic-con in Seattle a couple years ago, he signed his SMBC-Theater DVD for us and posed for "photo bomb" pictures. Awesome dude. My question for Zach is, have you ever considered/pondered/done any longer-form comics, with a cohesive narrative? You have tons of goofy ideas, some quite entertaining, I'd love to see what you could do with a story-driven comic powered by your goofy ideas. Also: your wife is wrong, single-use monocles are an awesome idea, even if just for gag-gift purposes :P

Weiner: I’m working on one serious dramatic graphic novel and a few prose novels now. I’ve wanted to do longform stuff for a while, but it’s hard to find the time!

Glad you liked the monocles :) I think they’re hilarious, but I’ve never gotten so many angry messages (vapid consumerism! hipster bullshit! neckbearded nerds!) over a product before. It’s weird because people are ascribing all sorts of philosophical/social context to it that I just don’t see.



Any Public Response to the Common Criticism?
by eldavojohn

How do you respond to the criticism that by widely distributing your single use monocles to teenagers and adults, you'll be making highbrow socializing safer and therefore increase it to immoral levels?

Weiner: If one wishes to be a prig or a Puritan, one can flaunt one’s moral views about them, but they are not one’s concern. Besides, Individualism has really the higher aim. Modern morality consists in accepting the standard of one’s age. I consider that for any man of culture to accept the standard of his age is a form of the grossest immorality.



Do you have...
by serviscope_minor

Do you have any extra wisdom to share with us that's you know, like... woah? (For those less familiar with SMBC, this is one of my all time favorites.)

Weiner: Most people spend their lives in dread of the stuff that would make them happiest.

Also, no matter how good a giant Reese’s looks, it’ll never match your expectation.

An anonymous reader writes Citing a report from the Gartner Group estimating $100 billion in intellectual property losses within five years, Joshua Greenbaum warns of "the threat of a major surge in counterfeiting" as cheap 3-D printers get more sophisticated materials. Writing for Wired, Greenbaum argues that preventing counterfeiting "promises to be a growth market," and suggests that besides updating IP laws, possible solutions include nanomaterials for "watermarking" authentic copies or even the regulation of 3-D printing materials. Major retailers like Amazon are already offering 3-D print-on-demand products — though right now their selection is mostly limited to novelties like customized bobbleheads and Christmas ornaments shaped like cannabis leaves. Apropos: Smithonian Magazine has an article that makes a good companion piece to this one on the long political history of the copy machine, which raised many of the same issues being rediscovered in the context of 3-D printing.

New submitter Solandri writes: When Mt. Vesuvius erupted in A.D. 79, it destroyed a library of classical works in Herculaneum. The papyrus scrolls weren't incinerated, but were instead carbonized by the hot gases. The resulting black carbon cylinders have mostly withstood attempts to read their contents since their discovery. Earlier attempts to unfurl the scrolls yielded some readable material, but were judged too destructive. Researchers decided to wait for newer technology to be invented that could read the scrolls without unrolling them.

Now, a team led by Dr. Vito Mocella from the National Research Council's Institute for Microelectronics and Microsystems (CNR-IMM) in Naples, Italy has managed to read individual letters inside one of the scrolls. Using a form of x-ray phase contrast tomography (abstract), they were able to ascertain the height difference (about 0.1mm) between the ink of the letters and the papyrus fibers which they sat upon. Due to the fibrous nature of the papyrus and the carbon-based ink, regular spectral and chemical analysis had thus far been unable to distinguish the ink from the paper. Further complicating the work, the scrolls are not in neat cylinders, but squashed and ruffled as the hot gases vaporized water in the papyrus and distorted the paper.

HughPickens.com writes Nicholas St. Fluer reports at The Atlantic that according to researchers, our convenient, sedentary way of life is making our bones weak foretelling a future with increasing fractures, breaks, and osteoporosis. For thousands of years, hunter-gatherers trekked on strenuous ventures for food with dense skeletons supporting their movements and a new study pinpoints the origin of weaker bones at the beginning of the Holocene epoch roughly 12,000 years ago, when humans began adopting agriculture. "Modern human skeletons have shifted quite recently towards lighter—more fragile, if you like—bodies. It started when we adopted agriculture. Our diets changed. Our levels of activity changed," says Habiba Chirchir. A second study attributes joint bone weakness to different levels of physical activity in ancient human societies, also related to hunting versus farming.

The team scanned circular cross-sections of seven bones in the upper and lower limb joints in chimpanzees, Bornean orangutans and baboons. They also scanned the same bones in modern and early modern humans as well as Neanderthals, Paranthropus robustus, Australopithecus africanus and other Australopithecines. They then measured the amount of white bone in the scans against the total area to find the trabecular bone density. Crunching the numbers confirmed their visual suspicions. Modern humans had 50 to 75 percent less dense trabecular bone than chimpanzees, and some hominins had bones that were twice as dense compared to those in modern humans. Both studies have implications for modern human health and the importance of physical activity to bone strength. "The lightly-built skeleton of modern humans has a direct and important impact on bone strength and stiffness," says Tim Ryan. That's because lightness can translate to weakness—more broken bones and a higher incidence of osteoporosis and age-related bone loss. The researchers warn that with the deskbound lives that many people lead today, our bones may have become even more brittle than ever before. "We are not challenging our bones with enough loading," says Colin Shaw, "predisposing us to have weaker bones so that, as we age, situations arise where bones are breaking when, previously, they would not have."

HughPickens.com writes The LA Times reports that Ls Angeles Mayor Eric Garcetti has proposed the most ambitious seismic safety regulations in California history that would require owners to retrofit thousands of buildings most at risk of collapse during a major earthquake. "The time for retrofit is now," says Garcetti, adding that the retrofits target buildings "that are known killers. Complacency risks lives. One thing we can't afford to do is wait." The mayor's plan calls for thousands of wood buildings to be retrofitted within five years, and hundreds of concrete buildings to be strengthened within 30. The retrofitting requirements must be approved by the City Council, and would have to be paid for by the building owners, with the costs presumably passed on to tenants and renters. The costs could be significant: $5,000 per unit in vulnerable wooden buildings and $15 per square foot for office buildings, Business owners, who have expressed concern in the past that these kinds of programs may be unaffordable, said the cost of retrofitting some buildings could easily exceed $1 million each. "This will cost us billions of dollars in the private and public sector," says Garcetti. "But we cannot afford not to do it."

The last major earthquake in Los Angeles was the 6.7-magnitude Northridge quake, which killed close to 60 people in 1994. But it was not close to the catastrophe that seismologists predict if there is a major shift on the San Andreas fault, and the fact that it has not produced a major quake in recent years has fed a sense of complacency. Seismologists now say a 7.5-magnitude event on the Puente Hills would be "the quake from hell" because it runs right under downtown Los Angeles and have estimated that would kill up to 18,000 people, make several million homeless, and cause up to $250 billion in damage. "We want to keep the city up and running after the earthquake happens," says Lucy Jones aka "The Earthquake Lady," a seismologist with the United States Geological Survey and something of a celebrity in a city that is very aware of the potential danger of its location. "If everything in this report is enacted, I believe that L.A. will not just survive the next earthquake, but will be able to recover quickly."

theodp writes After an NPR podcast fingered the marketing of computers to boys as the culprit behind the declining percentages of women in undergraduate CS curricula since 1984 (a theory seconded by Smithsonian mag), some are concluding that NPR got the wrong guy. Calling 'When Women Stopped Coding' quite engaging, but long on Political Correctness and short on real evidence, UC Davis CS Prof Norm Matloff concedes a sexist element, but largely ascribes the gender lopsidedness to economics. "That women are more practical than men, and that the well-publicized drastic swings in the CS labor market are offputting to women more than men," writes Matloff, and "was confirmed by a 2008 survey in the Communications of the ACM" (related charts of U.S. unemployment rates and Federal R&D spending in the '80s). Looking at the raw numbers of female CS grads instead of percentages, suggests there wasn't a sudden and unexpected disappearance of a generation of women coders, but rather a dilution in their percentages as women's growth in undergrad CS ranks was far outpaced by men, including a boom around the time of the dot-com boom/bust.

An anonymous reader writes in with news about maps attributed to Marco Polo that seem to show the coast of Alaska. "For a guy who claimed to spend 17 years in China as a confidant of Kublai Khan, Marco Polo left a surprisingly skimpy paper trail. No Asian sources mention the footloose Italian. The only record of his 13th-century odyssey through the Far East is the hot air of his own Travels, which was actually an "as told to" penned by a writer of romances. But a set of 14 parchments, now collected and exhaustively studied for the first time, give us a raft of new stories about Polo's journeys and something notably missing from his own account: maps. If genuine, the maps would show that Polo recorded the shape of the Alaskan coast—and the strait separating it from Asia—four centuries before Vitus Bering, the Danish explorer long considered the first European to do so. Perhaps more important, they suggest Polo was aware of the New World two centuries before Columbus."

sciencehabit writes: Eating food contaminated with radioactive particles may be more perilous than previously thought — at least for insects. Butterfly larvae fed even slightly tainted leaves collected near the Fukushima Daiichi Nuclear Power Station were more likely to suffer physical abnormalities and low survival rates than those fed uncontaminated foliage, a new study finds. The research suggests that the environment in the Fukushima region, particularly in areas off-limits to humans because of safety concerns, will remain dangerous for wildlife for some time. In other lingering radiation news, reader Rambo Tribble writes: Forest detritus, contaminated in the aftermath of the 1986 Chernobyl disaster (abstract), is decaying at a much slower rate than normal, building up and creating a significant fire risk. This, in turn, is creating a real potential for the residual radioactive material to be distributed, through smoke, over a broad area of Europe and Russia. Looking at different possible fire intensities, researchers speculate, "20 to 240 people would likely develop cancer, of which 10 to 170 cases may be fatal." These figures are similar to those hypothesized for Fukushima.

Rambo Tribble (1273454) writes "Programmers at Fast Company are developing the Cosmos browser to allow text browsing from Android phones when networks are buckling under the load of local disasters.

The Cosmos browser is intended to facilitate using SMS text messages, which often still get through in such circumstances. To quote one developer, "We want this to be a way for people to get information when they're in dire need of it." Sort of a Lynx comes to Android affair. The Smithsonian contemplates the possibilities, here."

An anonymous reader writes: Narcotic painkillers aren't one of the biggest killers in the U.S., but overdoses do claim over 15,000 lives per year and send hundreds of thousands to the emergency room. Because of this, it's interesting that a new study (abstract) has found states that allow the use of medical marijuana have seen a dramatic reduction in opioid overdose fatalities. "Previous studies hint at why marijuana use might help reduce reliance on opioid painkillers. Many drugs with abuse potential such as nicotine and opiates, as well as marijuana, pump up the brain's dopamine levels, which can induce feelings of euphoria. The biological reasons that people might use marijuana instead of opioids aren't exactly clear, because marijuana doesn't replace the pain relief of opiates. However, it does seem to distract from the pain by making it less bothersome." This research comes at a time when the country is furiously debating the costs and benefits of marijuana use, and opponents of the idea are paying researchers to paint it in an unfavorable light.

An anonymous reader writes "Smithsonian Magazine has an article about one of the non-obvious effects of the Chernobyl nuclear meltdown: dead organisms are not decomposing correctly. 'According to a new study (abstract) published in Oecologia, decomposers—organisms such as microbes, fungi and some types of insects that drive the process of decay—have also suffered from the contamination. These creatures are responsible for an essential component of any ecosystem: recycling organic matter back into the soil. Issues with such a basic-level process, the authors of the study think, could have compounding effects for the entire ecosystem.' The scientists took bags of fallen leaves to various areas around Chernobyl and found that locations with more radiation caused the leaves to retain more than half of their original weight after almost a year. They're now beginning to worry that almost three decades of dead brush buildup is contributing to the area's fire risk, and a large fire could distribute radioactive material beyond Chernobyl's exclusion zone."

Hugh Pickens DOT Com writes "Joseph Stromberg writes in Smithsonian Magazine that while the practice of solitary confinement is being discontinued in most countries, it's become increasingly routine within the American prison system. It is estimated that between 80,000 and 81,000 prisoners are in some form of solitary confinement nationwide. Once employed largely as a short-term punishment, it's now regularly used as way of disciplining prisoners indefinitely, isolating them during ongoing investigations, coercing them into cooperating with interrogations and even separating them from perceived threats within the prison population at their request.

Most prisoners in solitary confinement spend at least 23 hours per day restricted to cells of 80 square feet, not much larger than a king-size bed, devoid of stimuli (some are allowed in a yard or indoor area for an hour or less daily), and are denied physical contact on visits from friends and family ... A majority of those surveyed experienced symptoms such as dizziness, heart palpitations, chronic depression, while 41 percent reported hallucinations, and 27 percent had suicidal thoughts...

But the real problem is that solitary confinement is ineffective as a rehabilitation technique and indelibly harmful to the mental health of those detained achieving the opposite of the supposed goal of rehabilitating them for re-entry into society. Rick Raemisch, the new director of the Colorado Department of Corrections, voluntarily spent twenty hours in solitary confinement in one of his prisons and wrote an op-ed about his experience in The New York Times. 'If we can't eliminate solitary confinement, at least we can strive to greatly reduce its use,' wrote Raemisch."

Hugh Pickens DOT Com writes "About 252 million years ago, cracks in the Earth's crust in Siberia caused vast amounts of lava to spill out and blanket the region with about 6,000,000 cubic kilometers of molten material—enough to cover the continental U.S. at a one mile depth. It triggered a huge change in climate, causing a mass extinction event that killed roughly 90 percent of life on earth. Now Helen Thompson writes in the Smithsonian that a team at MIT has focused its efforts on this major extinction event, which marks the end of the Permian period and the beginning of the Triassic period. Their results suggest that the die-out happened a lot faster than previously thought — perhaps over a span of only 60,000 years. The shorter time scale means that organisms would have had less time to react and adapt to changes in climate, atmospheric CO2 and ocean acidity. Without the ability to adapt, they died. Other mass extinction events have also been narrowed down to short timeframes. The asteroid impact that killed the dinosaurs at the end of the Cretaceous period only took about 32,000 years. A similar study of another mass extinction triggered by volcanic eruptions at the end of the Triassic period suggests it lasted less than 5,000 years. Even though all of these extinction events were caused by different things, the ecosystem collapse happened very quickly. 'Whatever the causes of the extinctions may be, and it looks like there are very different causes for some of them, the biosphere may collapse in very similar ways once it gets beyond a tipping point,' says Doug Erwin. Some scientists see the end of the Permian as a lesson for the 21st century (PDF) and say that understanding the conditions leading up to, within, and after a mass extinction event may help us to avoid human-induced ecosystem collapses in the future. As Erwin puts it, 'you don't want to start a mass extinction, because once a mass extinction begins, the prognosis is pretty grim.'"

A new study has been published in Nature Geoscience (abstract) detailing how scientists correctly anticipated the location and strength of an earthquake earlier this year. On September 5th, a 7.6 earthquake rocked Costa Rica's Nicoya Peninsula. That region had seen earthquakes of (roughly) magnitude 7 in 1853, 1900, and 1950, so "geoscientists had forecast that a magnitude 7.7 to 7.8 quake should occur around the year 2000, plus or minus 20 years." "The Nicoya Peninsula is prone to earthquakes because it's an area of subduction, where the Cocos Plate is pushing underneath the Caribbean Plate, moving at a rate of about 8.5 centimeters per year. When regions such as this suddenly slip, they produce a megathrust earthquake. Most of the world's largest earthquakes — including the magnitude 9.0 Tohoku-Oki quake in Japan in 2011 and the magnitude 9.15 Sumatra-Andaman earthquake in 2004, both of which produced devastating tsunamis — fall into this category. .. The close study of this region allowed scientists to calculate how much strain was building in the fault and in May 2012 they published a study in which they identified two locked spots capable of producing an earthquake similar to the one in 1950. In September of that year, the landward patch ruptured and produced the earthquake. The offshore one is still locked and capable of producing a substantial but smaller earthquake, an aftershock with a magnitude as high as 6.9, the researchers say."

Hugh Pickens DOT Com writes "Google recently helped celebrate the 100th anniversary of the first "word cross" puzzle (the name soon changed), which appeared in the New York World on Dec. 21, 1913. Credited to cruciverbalist Arthur Wynne they soon spread to other papers and by the 1920s, the decade of fads and fashions, crossword puzzles were up there with flagpole sitting, goldfish swallowing, raccoon coats, monkey gland implants, Charleston contests and ukuleles as the very embodiment of mad, reckless youth on its never-ending quest for novelty. When crossword puzzles were at the height of popularity, they spawned a cadre of haters — mostly self-styled intellectuals, who found them idiotic, exasperating, even alarming. The sight of a dozen commuters doing crossword puzzles on the morning train was as irritating to some cranky people, then, as the sight of a dozen teens absorbed in their iPhones might seem today. These days, crossword puzzles are the highly respectable pastime of brainy people. The New York Times runs crosswords that increase in difficulty throughout the week; its crosswords editor, Will Shortz, is a minor celebrity. Champions vie to out-cross each other in the American Crossword Puzzle Tournament. Merl Reagle, who creates crosswords for the Washington Post, believes that while puzzles have changed over the years, their basic appeal remains the same. 'My theory is that it's because of their interlocking nature. Unlike a lot of other kinds of puzzles, every answer you get helps you get the next one.' Bernice Gordon, a 99-year-old crossword constructor who designs puzzles for The New York Times and other publications, says she owes her longevity in part to crosswords. 'I couldn't live without them,' says Gordon. 'It's my lifeblood. I don't sleep at night because I think, 'What rhymes with "ritz" and "sits" and "pits"?' I do my best work from 2 a.m. to 6 a.m.'"

cold fjord writes "UPI reports, 'Eighty percent of scientific data are lost within two decades, disappearing into old email addresses and obsolete storage devices, a Canadian study (abstract, article paywalled) indicated. The finding comes from a study tracking the accessibility of scientific data over time, conducted at the University of British Columbia. Researchers attempted to collect original research data from a random set of 516 studies published between 1991 and 2011. While all data sets were available two years after publication, the odds of obtaining the underlying data dropped by 17 per cent per year after that, they reported. "Publicly funded science generates an extraordinary amount of data each year," UBC visiting scholar Tim Vines said. "Much of these data are unique to a time and place, and is thus irreplaceable, and many other data sets are expensive to regenerate.' — More at The Vancouver Sun and Smithsonian."
