Slashdot Mirror

An anonymous reader writes "LiveScience is reporting on what appears to be the first digital simulation of an entire life form. Researchers created more than a million digital atoms to reverse engineer the satellite tobacco mosaic virus, a relatively simple organism. But is it really a life form? From the article: 'Viruses are tiny bundles of protein and genetic material that straddle the line between life and non-life. Many scientists prefer to call them "particles" because even though they contain RNA or DNA like other lifeforms, they can only replicate inside other living cells.'"

starexplorer2001 writes "LiveScience is reporting how scientists at Sandia's Z laboratory have produced superheated gas exceeding temperatures of 3.6 billion degrees Fahrenheit (2 billion kelvins). That's hotter than the interior of our sun, which is only 15 million degrees F. And they don't know how they did it. Do we want anything that hot on our planet?"

chaosmage42 writes "Scientists at the University of Dublin have found a way to break down styrofoam, the bane of recyclers/composters everywhere. This could be a great step towards sustainability, but it does require the styrofoam to be heated first."

An anonymous reader writes "LiveScience has an interview with Physicist, novelist, and science writer, Alan Lightman with regards to the future of science and what the next "big" discoveries might be. From the article: "Generally attack against science is part of a greater attack against intellectualism in general. I think right now we're in an anti-intellectual period in the United States, but I think the pendulum will swing back in the other direction again."

An anonymous reader writes "Researchers created an artificial music market of 14,341 participants split into two groups to pick music from unknown musicians. In one group, the individuals had only song titles and band names to go on. The individuals in the other group saw how others had rated the songs. Turns out popularity bred popularity, which explains why there's so much crap on the radio."

Zoner12 writes "LiveScience magazine is running an interesting article about a new study detailing the extent and seriousness of spyware on the Internet, finding that it is still prevalent but declined significantly. The scary statistic is that 1 in 62 websites visited distributes malware. Kind of disheartening that this is a decline."

An anonymous reader writes "LiveScience is reporting that Tien Wong, of the Center for Eye Research Australia at the University of Melbourne, is claiming that abnormalities in the blood vessels of the retina can be used to predict diabetes, hypertension, stroke, and heart disease. These results were the culmination of several large studies. This could go a long way towards advancing medicine in the developed world as these disorders are some of the most common causes of death, hospitalization, and disability."

Snap E Tom writes "As of this past Friday, Western Union has stopped sending telegrams. The article cites factors such as long distance telephone and faxes that contributed to its demise, but email was the final nail. My hunch is that modern USPS and overnight delivery services did the most damage, though."

An anonymous reader writes to tell us LiveScience is reporting that Archaeologists may have found the oldest remains of slaves brought from Africa to the New World. From the article: "The African origin of the slaves was determined by studying a chemical in their tooth enamel that reveals plant and rock types of their native land. The chemical enters the body through the food chain as nutrients pass from bedrock through soil and water to plants and animals. It is an indelible signature of birthplace, the researchers said, because it can be directly linked to the bedrock of specific locales."

An anonymous reader writes "Larry Page and Craig Venter are now on the X Prize Board of Trustees, and Peter Diamandis, the man behind the $10 million space prize, said new X prizes are in the works for innovations in automobiles, education, nanotech and DNA reseach. Diamandis, from the article: "Why do we still drive cars that use an internal combustion engine and only get 30 miles per gallon? I think that we'll see some amazing achievements in this area." This is in addition to the foundation's incentive to completely decode the DNA of 100 or more people covered earlier on Slashdot."

An anonymous reader writes "LiveScience reports on research indicating that certain monkeys act like cops in a group. When they removed the enforcers, the monkey society fell apart. The rest of the monkeys quickly formed cliques with friends and family and interaction between the groups ceased. More interesting is how the monkeys 'vote' for their law enforcement officials, by baring their teeth to show deference. From the article: 'When an individual receives these voting signals from most of the group, it shows he is well respected--or feared--and he becomes the new sheriff in town.'"

An anonymous reader writes "Any democrat will tell you the republicans ignore the facts. Any republican will tell you the democrats ignore the facts. Turns out they're right. A new study monitored brain activity of partisans; they shun logic and use emotional processing centers to justify their candidate's contradictory statements. 'With their minds made up, brain activity ceased in the areas that deal with negative emotions such as disgust. But activity spiked in the circuits involved in reward, a response similar to what addicts experience when they get a fix.'"

An anonymous reader writes "LiveScience has an interesting piece taking a look at how genius is rarely developed in a vacuum. From the article: 'The reality is that behind many scientific geniuses, there is at least one other genius, and often a number of them.' It takes much more than a genius pal or predecessor, however, to do great science, according to Simmons. Scientific advances emerge from social, economic and political conditions."

An anonymous reader writes "LiveScience has a story about a surprisingly simple experiment (yes, you can try this at home) at room temperature that yielded a jet of sand that behaves similar to jets created in ultra-dense gas near absolute zero. From the article: 'We're discovering a new type of fluid state that seems to exist in this combination of gas--air in this case--and a dense arrangement of particles.'"

starexplorer writes "Start your Nano-engines? LiveScience.com is reporting that researchers at Rice University have designed the world's smallest car that is no more than 4 nanometers across. It has a chassis, axles and a pivoting suspension. The wheels are buckyballs. Why do it? The team wants to build a fleet of nanotrucks to carry atoms and molecules around minature factories." So it's not exactly self-powered, but it rolls. It's a start!

fm6 writes "LiveScience is reporting that the 21 names reserved for tropical storms and hurricanes in Atlantic Basic are almost used up. If there are more than 21 storms, they'll start using the Greek alphabet. The most storms ever recorded was 21 in 1933, before they started giving them official names. The connection between this record-breaking storm year and global warming remains controversial."

starexplorer writes "LiveScience is reporting on an early conceptual design of The Walrus the DOD's new planned 'very large airlift vehicle'." Could the concept of a 'war-balloon' really be gaining favor again?

nedwolf writes "LiveScience is reporting that a 100 square mile bulge has been rising in Oregon. First observed from a satellite using a relatively new technology called 'radar interferometry', some believe this to be the formation of a new volcano. I think it's just happy to see me."

Ant writes "According to a LiveScience story, a steady diet of email spam can be good for you. From the article: 'Researchers split a group of more than 2,100 Canadians into two groups. One group got e-mails that promoted healthy lifestyles, the other got none. "These were informative and motivational messages sent weekly for 12 weeks," explained study leader Ron Plotnikoff of the University of Alberta. The e-mails promoted the benefits of a good diet and physical activity. Those who were effectively spammed, as a group, saw their mean body mass index (BMI) go down, meaning it improved. BMI is a measure of body fat based on height and weight. Overall BMI rose for the control group, which did not get the emails.'"

Killer Instinct writes "Ever wonder how ice melts? Until now, scientists could not explain why ice cubes in your drink melt. They've known the basics, but the details remained elusive. A breakthrough new study, announced yesterday, supports a leading theory that melting starts when the fundamental structure of matter begins to crack. Melting is considered a basic phenomenon in physics. An understanding of how it works is crucial to gaining a firm grasp on the physical world."

telstar writes "Though the debate continues around global warming, a new proposal suggests building an artificial space ring around the Earth to block the light of the sun and bring a balance to solar radiation, cloud cover, and heat-trapping greenhouse gases. The ring could be comprised of particles which would scatter the sunlight, or be built by an interconnected ring of spaceships aligned to block the light. The former proposal is estimated to cost anywhere from $6 trillion to $200 trillion dollars, while the spaceship solution would run approximately $500 billion. Halo fans rejoice."

emtboy9 writes "Yahoo News is reporting that scientists at Sandia National Labs have created a magnetic pulse gun (rail gun) that can accelerate small aluminum plates at 34 kilometers per second, faster than the Earth travels through space. The accelerated plates strike a target after traveling only five millimeters, or less than a quarter-inch. The impact generates a shock wave -- in some cases, reaching 15 million times atmospheric pressure -- that passes through the target material turning matter into various states almost instantly (solids into liquids, liquids into gas, and even gas into plasma)."

johnsee writes "Microsoft is working with Ford Motor Co towards car that can't crash. The future of cars according to Gates will involve high-definition screens, speech recognition technology, cameras, digital calendars and navigation equipment with directions and road conditions." From the article: "Also on Friday, Microsoft unveiled its Performance Peak Initiative -- a line of computer systems to help the auto industry better coordinate supply chains, streamline design, production and sales and fill vehicles with computer gadgets."

hende_jman writes "Scientists at Princeton University successfully 'programmed bacteria to behave like computers, assembling themselves into complex shapes based on instructions stuffed into their genes.' Though applications may not come for awhile, the article says that in the future this technology may be used in devices to detect bioterrorism chemicals. The article also has pictures of the programmed E. coli."

AtariAmarok writes "A new article is up on LiveScience about a hole drilled into the Earth's crust to explore the layers of our planet's substrate. The hole gets closer to the mantle than any other efforts that have gone before. The hole might reach the "Moho" (division between Earth's brittle outer crust and the hotter, softer mantle) within a few years." From the article: "The depth of the Moho varies. This latest effort, which drilled 4,644 feet (1,416 meters) below the ocean seafloor, appears to have been 1,000 feet off to the side of where it needed to be to pierce the Moho, according to one reading of seismic data used to map the crust's varying thickness."

Neil Halelamien writes "Researchers at the University of Bath are developing a rapid prototyping machine capable of making copies of itself and other products, reminiscent of the Universal Constructor proposed by von Neumann. The so-called Replicating Rapid-Prototyper (or RepRap) would produce items from raw materials and small components like microchips. If successful, this could make rapid prototyping cheap enough for regular in-home usage, especially since the project's lead, Dr. Adrian Bowyer, will be releasing his project's designs under the GNU GPL. It's previously been proposed that a similar system would be useful for space exploration and industrialization."

An anonymous reader writes "Turns out the sun itself zaps the ozone that protects us from the sun. LiveScience is reporting that the record-setting string of solar storms around Halloween in 2003 (including an X28 flare) set off a cascade of events that depleted the ozone layer over the Arctic in early 2004. In a nutshell, more nitrogen was created, and an unusually strong vortex of high-speed winds aloft brought the nitrogen down, where it contributed to cutting ozone by 60 percent over the polar region. In January, the a European scientist warned residents of the far north to basically stay out of the sun. While chlorofluorocarbons are still blamed for ozone depletion, scientists said this study shows they don't properly account for the sun's impact."

An anonymous reader writes "LiveScience is now reporting that Burt Rutan's GlobalFlyer is set for Monday takeoff. The plane, piloted by Steve Fossett, has been grounded since January by weather. The mission: the first solo, nonstop circumnavigation of the globe via jet powered craft without refueling." Commentary also available from the BBC.

An anonymous reader writes "LiveScience is reporting on a new type of bacteria that after being frozen 32,000 years in the Arctic was ready to swim, eat and multiply instantly upon being thawed. Researchers are excited because they're the sort of microbes that might thrive in the ice sea announced on Mars yesterday. The instant revival abilities mean a future mission, if it found anything on Mars, could conceivably culture it and bring it back alive. Maybe NASA could market them as Martian Sea Monkeys."

An anonymous reader writes "There are a few robots that do amazing things. Honda's Asimo can walk backward and climb stairs. Sega's idog can dance to music. A tougher nut to crack has been making robots walk like humans. Today, scientists introduce three humanoid striders at the annual AAAS meeting. Unlike other robots that have to power every move, these three save energy by letting gravity do a lot of the work. Like humans, they pick up their feet and just let 'em drop. Engineers say they'll inform the next generations of humanoids and also improve design of robotic prostheses for people. And hey, why not send them to Mars to look for those microbes?"

People perceived as the most likely to succeed might also be the most likely to crumble under pressure. A new study finds that individuals with high working-memory capacity, which normally allows them to excel, crack under pressure and do worse on simple exams than when allowed to work with no constraints. Those with less capacity score low, too, but they tend not to be affected by pressure.

An anonymous reader writes "LiveScience is reporting that the military's HAARP project has had its first success generating artificial light displays in the ionosphere. They created little green speckles of manmade aurora within an existing auroral display. The work is designed primarily to 'enhance communications and surveillance systems for both civilian and defense purposes.' Next up: sky-high neon advertisements."

An anonymous reader writes "Give a monkey some spending money, and he'll blow it on pictures of women monkeys. He'll also pay to see dominant monkeys. But you'll have to pay him to look at inferior monkeys. That's the upshot of a study out of Duke that was designed to explore the 'social machinery of the brain with an eye toward helping autism patients.' Next up -- seriously -- the researchers want to run the same test on Joe Sixpack (sans the monkey business)."

An anonymous reader writes "Logical to assume that scientists know the structure of water. But wrong. A study in April by Anders Nilsson from the Stanford Linear Accelerator Center concluded the molecular bonds are looser than thought. Now a new study by Richard Saykally's group at UC Berkeley appears to debunk the April results. So a new debate is born. Both scientists agree on one thing: They don't fully understand how water molecules interact."

An anonymous reader writes "Commercial silk comes not from spiders, but from the silk moth (spiders are hard to coral). But spider silk is stronger, so engineers, including in the Army, would like to use it for armor, tethers, and clothing. Scientists at Nexia Biotechnologies bioengineered some in 2002, but in a two-step process not ready for prime time. According to a LiveScience article, a separate team has now created self-spinning spider-web fiber. More work is still needed to produce anything useful, but the researchers say it might happen within a decade."

An anonymous reader writes "LiveScience is reporting on a study showing that people with chronic lower back pain have 5 to 11 percent less gray matter than pain-free folks. Its not known for sure why, but the thinking is that neurons just get worn out as the mind deals with the pain."

An anonymous reader writes "Scientists have long probed Earth's interior by monitoring seismic waves (if earthquakes don't make them, they can be induced with explosives, and one nuke test actually triggered an earthquake!), which reveal the inner structure of the planet. But what if the method is wrong? LiveScience reports on a new study suggesting Earth is like a pinball machine, with sound waves careening around before they get to the surface. What is interpreted as a broad layer change could be nothing more than a localized density variation."

An anonymous reader writes "Ankylosaurs were the most heavily armored dinosaurs. Researchers thought their protective plates were a lot like modern crocodiles. But a new study by a University of Bonn grad student Torsten Scheyer found that fibers in the plates were woven for strength and lightness much like Kevlar or fiberglass. Good thing, as ankylosaurs had to contend with T. rex."

An anonymous reader writes "Scientists have known for years that insects and animals use distinct markings as status badges. Now, by staging wasp fights, researchers have learned that cheaters never win. Wimpy wasps painted with the markings reserved for a leader get beat up. Even if the fakes win, they still get harassed afterward. The study leader likened it to what might happen to a 97-pound weakling who walks around wearing a black belt. Sooner or later ..."
