Smart Power
ajnsue writes "How would you like to control your homes power consumption at the level of the appliance - About 300 Washington State and Oregon Power users are now testing software and devices that allow them to actively control their household power consumption based on the price of power. From the article... "...(Using)real-time price information (provided) through a broadband Internet connection and automated equipment that will adjust energy use based on price. In addition, some customers will have computer chips embedded in their dryers and water heaters that can sense when the power transmission system is under stress and automatically turn off certain functions briefly until the grid can be stabilized by power operators." This technology also provides beneift to the provider network "...The Grid Friendly TM Appliance Controller chip could help prevent widespread power outages by turning off certain parts of an appliance when it senses instability in the grid - something that happens about once a day on average. Shutting down the heating element for a few minutes, while the drum continues to tumble, would likely go unnoticed by the homeowner but drastically reduces power demand within the home..."" -
Glass Shapes Can Make Us Drink Too Much
Roland Piquepaille writes "Some people think that a glass is half empty while others see it as half full. But one thing is sure: some glasses are fuller than others. According to the British Medical Journal (BMJ), researchers from Cornell University and the Georgia Institute of Technology have shown that short glasses are more likely to lead to over-indulgence. In fact, people pour 20-30 percent more alcohol into short, wide glasses than into tall, narrow ones of the same volume. The researchers obtained similar results with students and professional bartenders. So, as New Year's Eve is coming, remember to use only tall glasses for your party!!!" -
Fructose Linked to Obesity, Diabetes
Engineer-Poet writes "Eurekalert announces that researchers at the University of Florida have demonstrated a link between fructose consumption and metabolic syndrome (a precursor of adult-onset diabetes). In part, it makes you feel hungrier than you should be. This is particularly bad for Americans, because sugar price supports have created a market for fructose as a substitute in almost everything. Dr. Richard J. Johnson says, "If you feed fructose to animals they rapidly become obese, with all features of the metabolic syndrome, so there is this strong causal link. And a high-fructose intake has been shown to induce certain features of the metabolic syndrome pretty rapidly in people." Eating fructose causes a rise in uric acid in the bloodstream. Uric acid in turn blocks the action of insulin, which regulates metabolism (including uptake by fat cells). Elevated uric acid levels can eventually cause features of metabolic syndrome, including high blood pressure, obesity and high cholesterol. The good news is that the action of uric acid can be blocked with drugs, and we can change what we eat. If enough of us boycott fructose and corn-syrup products, the market will respond." -
Fantastic Voyage Into the Heart
Roland Piquepaille writes "According to the Journal of Clinical Investigation (JCI), researchers from the Harvard Medical School have written a sequel to 'Fantastic voyage,' the 1966 sci-fi movie. By injecting self-assembling peptide nanofibers loaded with pro-survival factors into rats, they've showed that the animals could be protected from heart failures. So far, the researchers have not extended their experiments to humans." -
Finding a Needle in a Haystack of Data
Roland Piquepaille writes "Finding useful information in oceans of data is an increasingly complex problem in many scientific areas. This is why researchers from Case Western Reserve University (CWRU) have created new statistical techniques to isolate useful signals buried in large datasets coming from particle physics experiments, such as the ones run in a particle collider. But their method could also be applied to a broad range of applications, like discovering a new galaxy, monitoring transactions for fraud or identifying the carrier of a virulent disease among millions of people." Case Western has also provided a link to the original paper. [PDF Warning] -
Reduce Transistor Power Consumption
revelCyllufyalP writes to tell us that University of Kentucky researchers have discovered a way to reduce the overall power consumption of transistors. From the article: "In order to improve computer chips' performance, transistors' size and gate insulators have to be continuously shrunken so that more components can be packed into a single chip. Computer chip producers were hitting a wall in downscaling the transistors and gate insulators because of their inability to reduce the leakage current of the existing gate insulators. This new technique will help the chip producers to develop more powerful chips with low-power consumption." -
Molecular Motors on the Run
Roland Piquepaille writes "In the nanotech world, molecular 'motors' have been heavily investigated during the last decade. And you probably read that these nano-carriers will one day be able to move a useful drug right where it's needed inside your body. But think for a minute to the size gap between yourself and a molecule. It's pretty impressive! Now, according to this news release, researchers from the Max Planck Institute of Colloids and Interfaces in Germany have developed a theory stating that only a few motor molecules should be enough for directed transport over centimeters or even meters. It's probably a meaningless comparison, but it's like if you were able to walk to the moon and come back." -
Smart Bees Continue to Draw Interest
Roland Piquepaille writes "Researchers from University College London (UCL) have shown that bees are able to solve complicated color puzzles. In their study, bees were trained to find artificial flowers containing a nectar reward and colored in blue. Then they removed the nectar and put at random artificial flowers illuminated by yellow, blue, yellow and green lights. But wherever the blue flowers were, the bees continued to select them even if there was no longer a reward. These findings may soon lead to the design of sophisticated visual systems for autonomous robots." -
Pesticides Blamed for Fall in Male Fertility
hapdiddesigner writes "Man-Made Pesticides Blamed for Fall in Male Fertility Over Past 50 Years -- According to a new report by Michael Skinner of Washington State University in the June 3rd edition of Science Magazine, pesticides and environmental toxins can have a deleterious effect on fertility and susceptibility to disease for generations. A Commondreams.org posting of an Independent UK article states 'Pesticides and other man-made chemicals may lower male fertility for at least four generations, according to new research."' A Eurekalert.org copy of a Washington State University press release begins "A disease you are suffering today could be a result of your great-grandmother being exposed to an environmental toxin during pregnancy.'" -
Writing with a Nanoscale Fountain Pen
Roland Piquepaille writes "I'm sure that almost all of you have used a fountain pen. But imagine a pen drawing lines only 40 nanometers in width. Now, it can be done with the Nanofountain Probe (NFP) developed by scientists at Northwestern University. This innovative fountain pen "employs a volcano-like dispensing tip and capillary fed solutions to enable sub-100 nanometer molecular writing." But it needs to be mounted on an atomic force microscope (AFM) to be useful, so it probably is something you'll not find at your local drugstore for a while. However, this nanofountain probe could have applications for nanosensors, biotechnology and pharmaceuticals. Read more for other details, pictures and references." -
A New Way to Grow Bones
Roland Piquepaille writes "As it is often the case, a recent discovery just came out from a simple idea. By studying diseases in which the human body generates too much bone, UCLA researchers have discovered a natural molecule that can be used to generate new bone growth in patients who lack it. This new molecule has aptly been named UCB, or University of California Bone. This new protein for growing bones is more precise and has fewer side effects than the ones currently used by orthopedic surgeons to aid in bone repair. But if you suffer from a bone deficit today, you'll have to wait almost ten years before an FDA approval and a commercial introduction of products based on this discovery. Read more for other details and references, plus a picture of a bone defect corrected by the UCB." -
Smart Guns are Coming
wikinerd writes "Eurekalert reports that smart gun technology actually works. According to the press release, smart guns demonstrated by the NJIT, can recognise authorised users utilising "sixteen electronic computerized sensors embedded in the gun's grip" and "Under New Jersey law, passed in Dec. 2002, only smart guns can be purchased in the state three years after personalized handguns become commercially available. Lautenberg said New Jersey's legislative effort to introduce smart gun technology should be a national model for the country"." -
Transparent Transistors Are Coming
Roland Piquepaille writes "Transparent electronics is an emerging technology which aims to produce invisible electronic circuits. Now, researchers from Oregon report they made a major advance in transparent electronics. Their zinc-tin-oxide 'thin-film' materials are amorphous, physically robust, chemically stable and cheap to produce at just above room temperature. These new materials and transistors offer many new possibilities for consumer electronics, transportation, business and the military." -
Hardware That Recognizes You
Amit Upadhyay writes "Gizmodo is reporting about extra funding for smart guns at NJIT. Few have qualms about it, mostly on the line of: would optical sensor for finger prints work when the hand is soaked with blood? Would you get time to enter the override code in an emergency? But if we remove speculative emergency situations, the technology seems to be interesting. While checking out Fingkey Hamster what struck me was, this is one passkey I will not mind publishing on my webpage, and it can't be cracked, unless hardware tampering takes place. Kind of thing that you can put in all the car ignitions and lockers where password entry using keyboard can become too obtrusive." -
Mother Nature Does Nuclear Power
wjwlsn writes "Back in the day (2 billion years ago), even before the time of iron men and wooden reactors, Mother Nature had mastered nuclear power. She built a passively safe system at Oklo that had fully automatic control and built-in waste containment, and operated it safely for about 150 million years. Now researchers at Washington University in St. Louis have deduced the operational characteristics by examining the isotopic composition of xenon contained in rock samples taken from the reactor site. More details at Eurekalert." -
Estrogen Linked to Research and Programming Skills
Neil Halelamien writes "Psychologists at the University of Bath have found that male researchers and programmers tend to have higher levels of estrogen, a hormone which promotes development of the right side of the brain (responsible for spatial and analytical skills). Increased estrogen was also linked to having longer index fingers and a decreased likelihood of having children. Men teaching mathematics and physics tended to have unusually long index fingers, while women in the social sciences tended to have more testosterone. The psychologists also found that male and female students with a smaller difference between their index and ring finger lengths tended to do better on their Java programming exams. The research leaves open the question of why women (who typically have more estrogen than men) aren't more prevalent in the science and technology fields." -
New Lubricant Leads To Faster Hard Drives
azav writes "We all know about Moore's Law as it applies to chip speed but little attention is publicly made to the challenges of increasing speed in hard drives. A recent discovery in polyester (yes, polyester, you disco baby) lubricants will allow for faster and longer lasting hard drives." -
The World's First Origami Folding Robot
Roland Piquepaille writes "Devin Balkcom, a Carnegie Mellon graduate student in robotics, has built the world's first origami-folding robot as the subject of his thesis. Origami, the geometry of paper folding, looks simple when you're a kid. But it's actually quite challenging to design a robot to do it. Movements are quite complex, and paper, because it is flexible, is difficult to be manipulated by a robot. This news release says that the project uses kinematics, the study of mechanisms, to determine how folding is done and how paper can be treated as a flexible and rigid material. You'll find more details and references in this overview, including some frames extracted from videos showing the robot at work." Balkcom's website has movies, information and a couple of academic papers. -
New Quantum Cryptography Speed Record
Roland Piquepaille writes "Physicists from the National Institute of Standards and Technology (NIST) have established a world's speed record for 'unbreakable' encryption with their cryptographic system based on the transmission of single photons. With this kind of method, messages cannot be intercepted without detection, meaning transmission is always safe. The NIST 'quantum key distribution' (QKD) system was used between two buildings located 730 meters apart for transmitting a stream of photons at a rate of 1 million bits per second. While it might not look very fast, its 100 times faster than with previous quantum distribution systems. This overview contains more details and references about information theory." -
Morphing Plane Wings for Efficient Flights
Roland Piquepaille writes "Airplanes, whether manned or unmanned, need to travel at various speeds. For example, a surveillance plane needs to fly fast to reach its destination point. Then, it needs to reduce its speed to achieve its surveillance mission. But with its fixed wings, it doesn't offer the same level of efficiency during these two phases. That's why Penn State engineers have devised airplane wings that change shape like a bird and have scales like a fish. Right now, the team has only built a tabletop model. So it will be a long time before you catch a plane and watch the wings disappear by looking through the window. This overview contains more details and references, including a couple of images describing the work done so far." -
Satellites Show That Earth Has a Fever
Roland Piquepaille writes "A recent study from NASA says that satellites are acting as thermometers in space. Contrary to meteorological ground stations which measure the air temperature around two meters above the ground, satellites can accurately measure the temperature of the Earth's skin. And this new study, which covers the 18-year period going from 1981 to 1998, shows that the Earth's temperature is rising 0.43C per decade instead of the O.34C found by previous methods. Unfortunately for us, if satellites can more precisely measure this rise of the Earth's temperature, they cannot cure this fever. This overview contains more details and a spectacular image showing the European heat wave of the summer of 2003." -
From the Higgs Boson Particle to Leadbelly
Roland Piquepaille writes "Physicists from the Lawrence Berkeley National Laboratory are using the same methods to search for the elusive Higgs Boson particle and to digitally restore audio recordings from the past. Berkeley Lab signed an agreement with the Library of Congress to digitize the many thousands of early blues or jazz recordings it has in its archives. And the results are spectacular. Compare for example, these two versions of "Good Bye Irene", before and after being optically reconstructed (WAV format, 18 and 19 seconds). This news release describes the method used by the physicists. This overview contains other details and extra references about this project." We also covered finding Higgs Boson recently as well. -
Carbon From Outer Space Older Than Our Sun
Roland Piquepaille writes "While looking at interplanetary dust particles (IDPs) found in the Earth's stratosphere, researchers from the Washington University in St. Louis have found carbon older than the Solar System. They identified the organic material by its carbon isotopic composition, different from the one of carbon found on Earth. "Our findings are proof that there is presolar organic material coming into the Solar System yet today," said Christine Floss, the leading scientist. "This material has been preserved for more than 4.5 billion years, which is the age of the Solar System. It's amazing that it has survived for so long." This overview contains more details and references. It also contains pictures including the one of a sample's isotopic structure at a sub-micrometer scale." -
Sea Sponges Master Nano-technology
Mick Ohrberg writes "It has been discovered that sea sponges utilizes a biomolecular mechanism to direct nanofabrication of silica to create microscopic glass fibers. It's a protein that acts as a catalyst for the formation of glass from the biomineral. What's it all lead to? Hopefully a way to achieve nanostructural fabrication at low temperatures, instead of in vacuum and at high temperatures as with current technologies." -
Traditional Inuit Ice Treks Guided From Space
Roland Piquepaille writes "When the Arctic floe melts at spring, the Inuit are going for thousands of years to its edges for fishing and finding game. Now, they are helped by the European Space Agency (ESA) and its satellite which provide accurate maps of ice and its extent. These maps are also useful for tour guides and to improve safety. "The ESA-backed Northern View Floe Edge Information Service provides regularly updated ice maps of inlets around Lancaster Sound, part of Baffin Bay within Canada's Nunavut Territory. Users can access maps from the Floe Edge service directly via a dedicated website, or else consult printouts posted for the public by the local Parks Canada Office." This overview contains more details and references. It also includes an image generated by the Northern View Floe Edge product showing ice conditions." -
Detecting Patterns in Complex Social Networks
Roland Piquepaille writes "So-called social networking is very popular these days, as show the proliferation of services like Friendster, Orkut and dozens of others. But do the companies behind these services have any idea of what is hidden inside their complicated networks? When these networks reach a size of millions of users, it's not an easy task. A researcher at the University of Michigan is trying to help, with a new method for uncovering patterns in complicated networks, from football conferences to food webs. This overview contains more details and references about this non-traditional method. It also includes a spectacular representation of the Internet and another image showing a food web at Little Rock Lake." -
Chemists Crack Secrets of Mussels' Super Glue
Roland Piquepaille writes "Researchers from Purdue University working under an award from the National Science Foundation (NSF) have discovered that common blue mussels are using iron found in seawater to create their own super glue. "In addition to using the knowledge to develop safer alternatives for surgical and household glues, the researchers are looking at how to combat the glue to prevent damage to shipping vessels and the accidental transport of invasive species, such as the zebra mussel that has ravaged the midwestern United States." This overview contains more details and references about this discovery. You'll also find an image of mussel glue at a magnification of 25,000X and one of a mussel adhering to a sheet of Teflon." -
For Champagne Bubbles, Smaller Is Better
Roland Piquepaille writes "During this holiday season you don't need a special occasion to drink champagne. You can do it everyday, providing you use moderation and common sense. But did you know that champagne taste better when it has tiny bubbles? This is the result of a very serious study published by the American Chemical Society (ACS) and more recently found by the Discovery Channel. And why do you think champagne taste better when carrying smaller bubbles? The answer is pretty obvious. More bubbles are releasing the champagne's flavor and aroma into your mouth. This summary gives you more details. In the mean time, let's all drink champagne!" -
Fighting Cancer With The Common Cold?
Roland Piquepaille writes "After 30 years of work, Saint Louis University researchers have genetically engineered a common cold virus to fight cancerous cells while leaving unaffected healthy ones. They received a patent for this research and clinical tests on humans will start soon, according to this news release. Dr. William Wold, chair of the department of molecular microbiology and immunology, received the patent No. 6,627,190 for his work. Preclinical testing has already been done so clinical trials should start soon. We can only hope they will be successful. This overview contains many more details and references about this potential cure for all kinds of cancer. [Note: this is a very different project from the one mentioned by a previous Slashdot post.]" -
First Pure Nanotube Fibers Made
TheSync writes "Researchers at Rice have announced the discovery of how to create continuous fibers from single-wall carbon nanotubes (SWNT). The breakthrough was based on the ability to dissolve a large amount of SWNTs in sulfuric acid, up to 10% SWNTs in solution. At high concentrations, the SWNTs form tightly packed liquid crystals that can be processed into pure fibers. The Space Elevator can't be far away now..." -
Atoms Receive 'Movie Star' Treatment
Roland Piquepaille writes "A news release from the University of Toronto (U of T) says that a team of chemists has successfully captured images of atoms during the melting of aluminum. "Chemists at the University of Toronto have captured atom-scale images of the melting process-revealing the first images of the transition of a solid into a liquid at the timescale of femtoseconds, or millionths of a billionth of a second. The result is an unprecedented "movie" detailing the melting process as solid aluminum becomes a liquid." Can this be useful for you? Probably not. But these chemists think they have a new valuable tool which will allow them to make atomic movies of other chemical reactions. This summary contains more details and additional references." -
Smart Badges For Better Meetings
Roland Piquepaille writes "In an article appearing in the November 15th issue of New Scientist, we're told that the 500 attendants of the last Pop!Tech conference were carrying intelligent badges to put around their necks. EurekAlert! has released a version of this article, "Hello, will you be my friend?" These nTAGs, distributed by the nTAG Interactive company, contained personal details about their wearers. And as the nTags can communicate with each other via infrared links, they are able to send alerts when they see a good match between two owners. This doesn't come up cheap: expect $40 to $100 per badge per day, depending on the event. More details and references are contained in this overview which also includes pictures." -
Better Displays With New Nanowire Film
Roland Piquepaille writes "A Harvard University team has successfully applied a film of nanowires on glass and plastic. This might lead to better and flexible displays or wearable computers, says the American Chemical Society, in "Nanowire film brings cheaper, faster electronics a step closer." "By using a 'bottom-up' approach pioneered by our group, which involves assembly of pre-formed nanoscale building blocks into functional devices, we can apply a film of nanowires to glass or plastics long after growth, and do so at room temperature," says Charles M. Lieber, professor of chemistry at Harvard. The researchers think that the first applications will be improved smart cards or LCD displays. But they also have a vision for the next decade. "One could imagine, for instance, contact lenses with displays and miniature computers on them, so that you can experience a virtual tour of a new city as you walk around." This overview contains more details and references. It also includes a picture of a high-density crossbar nanostructure, whose geometry can serve as the basis for many applications, like bio-sensor arrays or high-density data storage." -
4 Tons Of Plants per Mile to Ride In Your Car
Roland Piquepaille writes "As you might know, I enjoy big numbers. So it's just natural that I was attracted by this news release from the University of Utah, "Bad Mileage: 98 tons of plants per gallon." "A staggering 98 tons of prehistoric, buried plant material is required to produce each gallon of gasoline we burn in our cars, SUVs, trucks and other vehicles." For a reasonably efficient car, riding 25 miles per gallon, this translates to 4 tons of prehistoric plants per mile, or more than two tons per kilometer. The research paper also mentions that everyday, we are using the fossil fuel equivalent of all the plants growing during a whole year just for our cars. Even if these numbers are too large, this still makes you think about how inefficient our cars are. This analysis describes the calculations and contains other details about the research paper which will be published in November by Climate Change." -
Satellite-Assisted European Road Tolls Next?
Roland Piquepaille writes "In 'Pay-as-you-go motoring just around the corner,' the European Space Agency (ESA) says that "road tolls could be made fairer if satellite-assisted distance pricing is implemented." Experiments are currently underway in Ireland, Portugal and Germany, before a possible extension to other countries. Potential benefits of such a road tolling system would be fairer implementation of charging on a 'pay for use' basis. All these experiments are using the US-operated Global Positioning System (GPS). But in 2010, when the system is fully implemented, it will use the Galileo satellite system." -
Solar System Fossils Found By Hubble
segment writes "Astronomers using NASA's Hubble Space Telescope have discovered three of the faintest and smallest objects ever detected beyond Neptune. Each lump of ice and rock is roughly the size of Philadelphia and orbits just beyond Neptune and Pluto, where they may have rested since the formation of the solar system 4.5 billion years ago. The objects reside in a ring-shaped region called the Kuiper Belt, which houses a swarm of icy rocks that are leftover building blocks, or "planetesimals," from the solar system's creation. The results of the search were announced by a group led by Gary Bernstein of the University of Pennsylvania at a meeting of NASA's Division of Planetary Sciences in Monterey, Calif." -
Cleaning the Environment with Iron Nanoparticles
Roland Piquepaille writes "In "Nanoscale Iron Could Help Cleanse the Environment," the National Science Foundation (NSF) reports that "nanoscale" powder made from iron could be used to clean contaminated soil and water. "Iron's cleansing power stems from the simple fact that it rusts. When metallic iron oxidizes in the presence of contaminants, these organic molecules get caught up in the reactions and broken down into simple carbon compounds that are far less toxic." Using this technology, cleaning landfills or industrial sites would cost about $5 per square meter. More details are available in this summary, including other links and a diagram showing how the method works." -
Nanoparticles Change Crystal Structure When Wet
Roland Piquepaille writes "This news release from the University of California at Berkeley is quite astonishing. 'A UC Berkeley team comprised of physicists, chemists and mineralogists reports on the unusual behavior of a semiconducting material, zinc sulphide (ZnS), when reduced to pieces only 3 nanometers across. They found that when the surface of a ZnS nanoparticle gets wet, its entire crystal structure rearranges to become more ordered, closer to the structure of a bulk piece of solid ZnS.' My summary includes two images of a 3 nanometer zinc sulphide (ZnS) nanoparticle with or without surface-bound water. How can this be used for? Surprisingly, they think that it 'could provide a way to tell whether pieces of rock from outer space came from planets with water.'" -
More on Spintronics
segment writes "'We have discovered the equivalent of a new 'Ohm's Law' for spintronics - the emerging science of manipulating the spin of electrons for useful purposes,' says Shoucheng Zhang, a physics professor at Stanford. 'Unlike the Ohm's Law for electronics, the new 'Ohm's Law' that we've discovered says that the spin of the electron can be transported without any loss of energy, or dissipation. Furthermore, this effect occurs at room temperature in materials already widely used in the semiconductor industry, such as gallium arsenide.'" -
There Is No Single Instant In Time
tekkieRich writes "Some interesting news from the world of physics. Supposedly, in this paper, the author answers some of the major paradoxes (achilles vs. the turtle and Zeno) concerning our understanding of time. 'Impressed with the work is Princeton physics great, and collaborator of both Albert Einstein and Richard Feynman, John Wheeler, who said he admired Lynds' "boldness," while noting that it had often been individuals Lynds' age that "had pushed the frontiers of physics forward in the past."'" -
Titania Nanotubes for Hydrogen Sensors?
Roland Piquepaille writes "Everybody is talking about carbon nanotubes these days. But what about titania nanotubes? Penn State researchers think they have a great potential for sensing hydrogen . According to this news release, "titania nanotubes are 1500 times better than the next best material for sensing hydrogen and may be one of the first examples of materials properties changing dramatically when crossing the border between real world sizes and nanoscopic dimensions, according to a Penn State materials scientist." And now, the very good news: titania nanotubes are cheap. So they'll be used in industrial quality control in food plants and as weapons against terrorism. My summary contains some more details." -
Romancing The Rosetta Stone
Roland Piquepaille writes "Not only this news release from the University of Southern California has a fantastic title, it also has a great content. This story is about one of their scientists, Franz Josef Och, whose software ranks very high among translation systems. "Give me enough parallel data, and you can have a translation system for any two languages in a matter of hours," said Dr. Och, paraphrasing Archimedes. His approach relies on two concepts, gathering huge amounts of data, and applying statistical models to this data. It completely ignores grammar rules and dictionaries. "Och's method uses matched bilingual texts, the computer-encoded equivalents of the famous Rosetta Stone inscriptions. Or, rather, gigabytes and gigabytes of Rosetta Stones." Read my summary for more details." -
Cheaper, Cleaner Hydrogen Without Platinum
keithww writes "Looks like the hydrogen economy may have gotten a whole lot cheaper. Wisconsin team engineers gas from biomass using common metals of tin, nickel, and aluminum instead of platinum. This looks like a good way to get rid of biowaste also." Of course, there's still a long way to go before the automotive industry is using it, but it is good news nonetheless. -
Accelerated Aging Gene Identified
bradbury writes "A host of news sources are carrying news that the gene responsible for Progeria, otherwise known as Hutchinson-Gilford Syndrome, has been identified as Lamin A (LMNA). Sources include a Eureka Alert article, a Science Daily article and a Nature Science Update article. Of interest is the fact that the gene causes at least 6 other genetic diseases. For the hard core science people, an extended discussion of LMNA can be found in the OMIM database here." -
Lose Weight The Slow, Boring Way
urbazewski writes "As spring gets underway (in the northern hemisphere anyway) it's a good time to start undoing the effects of a winter's worth of websurfing and gameplaying on your physical condition. A meta-analysis of studies of currently popular low carbohydrate diets by doctors at Stanford and Yale reveals that they are really just low calorie diets in disguise: 'findings suggest that if you want to lose weight, you should eat fewer calories and do so over a long time period." John Walker's 'engineer's approach' to losing weight is built around this astonishing insight, as described in his online book/weight loss plan The Hacker's Diet. The spreadsheets are out of commission, but the basic insights are an excellent antidote to fad diets." Ramen, Ramen, Ramen is not on the approved list. -
Rocky Mountains Keep Europe Warm
fldvm writes "The Earth Institute at Columbia University says that the rocky mountains are more responsible than the gulf stream for mild winters in Europe. See the press release, or google cache. The long held assumption had been that the warm water of the Gulf stream makes Western Europe warmer than Canada and and other parts at the same latitude. The researchers said that with computer models they removed the Gulf Stream and Europe stayed warm but when they flattened the mountains over North America the Eastern US was warmer and Europe was colder. " -
Small-Scale Warrior Robot Truck
Phoebus0 writes "The Oregon Health and Science University's Department of Computer Science and Engineering has been developing what looks like a massive robot truck of the future - only on a slightly smaller scale. It appears to use some fairly cool stuff on a really small platform, literally. It's called the Timbot, and is supposed to be able to act and get around independently, with only high-level instructions. The robot is running embedded Linux with 802.11b ethernet, a micro pan/tilt camera, and a bunch of other sensors. It's partially funded by DARPA, and the current press release can be found here. I want one!" I hope they commericialize and sell this, looks much better than my old Tonka truck. -
Securing Fiber Using Light Polarization
screenbert writes: "A new and novel way of communicating over fiber optics is being developed by physicists supported by the Office of Naval Research. Rather than using the amplitude and frequency of electromagnetic waves, they're using the polarization of the wave to carry the signal. Such a method offers a novel and elegant method of secure communication over fiber optic lines. This press release has more information. Of course I always thought that fiber was always pretty secure anyway since it's a lot harder to tap than copper." -
More Strange Bose-Einstein Condensate Behavior
Allen Varney writes "According to a story on EurekAlert, an arXiv preprint server paper titled 'Scattering of atoms on a Bose-Einstein Condensate' reports that atoms striking a BEC sometimes appears to leave before they enter. 'This doesn't imply a breaking of the light-speed barrier, time travel or anything overly exotic but is a property of waves being broken down into component parts and being reassembled slightly differently. [...] As an atom hits the BEC, it is absorbed into the collective state but still exists as a vibration. The vibration travels through the BEC but can escape as an atom once more. The study reinforces the similarity between atoms as waves and light as waves.' Slashdot has talked about supposed faster-than-light travel once or twice (or more) before." -
