Surgeons Weld Wounds Shut With Surgical Laser 151

Ruach writes "The promise of medical lasers goes beyond clean incisions and eye surgery: Many believe that lasers should be used not just to create wounds but to mend them too. Abraham Katzir, a physicist at Tel Aviv University, has a system that may just do the trick and is proving successful in its first human trials."

Quantum Cryptography Broken, and Fixed 118

schliz writes in with research out of Sweden in which researchers showed that, looking at a quantum cryptographic system as a whole, it was possible for an eavesdropper to extract some information about the QC key, thus reducing the security of the overall system. The team then proposed a cheap and simple fix for the problem. "The advanced technology was thought to be unbreakable due to laws of quantum mechanics that state that quantum mechanical objects cannot be observed or manipulated without being disturbed. But a research team at Linköping University in Sweden claim that it is possible for an eavesdropper to [get around the limitations] without being discovered. In a research paper, published in the international engineering journal IEEE Transactions on Information Theory (abstract), the researchers propose a change in the quantum cryptography process that they expect will restore the security of the technology."

Scientists Build New Type of Photon Gun 90

KentuckyFC writes "Single photons are surprisingly difficult to generate. But since they are crucial for quantum communication, a number of research groups are working on photon guns that fire single photons on demand. The problem they have come up against is that making the photons identical is proving harder than expected. Now a group in Cambridge, UK, has cracked the problem using a quantum dot on a transistor to emit single photons that are essentially identical. In the process, the group has developed an entirely new technique to trigger photon emission (abstract on the physics arxiv)."

New Type of Fatigue Discovered in Silicon 108

Invisible Pink Unicorn writes "Researchers at the National Institute of Standards and Technology (NIST) have discovered a phenomenon long thought not to exist. They have demonstrated a mechanical fatigue process that eventually leads to cracks and breakdown in bulk silicon crystals. Silicon — the backbone of the semiconductor industry — has long been believed to be immune to fatigue from cyclic stresses because of the nature of its crystal structure and chemical bonds. However, NIST examination of the silicon used in microscopic systems that incorporate tiny gears, vibrating reeds and other mechanical features reveals stress-induced cracks that can lead to failure. This has important implications for the design of new silicon-based micro-electromechanical system (MEMS) devices that have been proposed for a wide variety of uses. The article abstract is available from Applied Physics Letters."

Ultracapacitors Soon to Replace Many Batteries? 415

einhverfr writes "According to an article in the IEEE Spectrun, the synergy between batteries and capacitors — two of the sturdiest and oldest components of electrical engineering — has been growing, to the point where ultracapacitors may soon be almost as indispensable to portable electricity as batteries are now. Some researchers expect to soon create capacitors capable of storing 50% as much energy as a lithium ion battery of the same size. Such capacitors could revolutionize many areas possibly from mobile computing (no worries about battery memory), electricity-powered vehicles, and more."

Texting Teens Generating OMG Phone Bills 888

theodp writes "Last month, Washington high school junior Sofia Rubenstein used 6,807 text messages, which, at a rate of 15 cents apiece for most of them, pushed her family's Verizon Wireless bill over $1,100. She and other teens are finding themselves in hot water after their families get blindsided with huge phone bills thanks to hefty a la carte text messaging charges." Use of SMS in the US doubled from 2005 to 2006.

Norway Outlaws iTunes 930

haddieman notes that while many people are getting more and more annoyed at DRM, Norway actually did something about it. The PC World article explains: "Good intentions, questionable execution. European legislators have been giving DRM considerable attention for a while, but Norway has actually gone so far as to declare that Apple's iTunes store is illegal under Norwegian law. The crux of the issue is that the Fairplay DRM that is at the heart of the iTunes/iPod universe doesn't work with anything else, meaning that if you want access to the cast iTunes library, you have to buy an iPod."

Nanobatteries — Safer By Design 83

Iddo Genuth writes "Conventional Li-Ion batteries have been known to catch fire and explode. A new, safer type of Li-Ion nanobattery that might help prevent such mishaps has been developed by researchers at Tel Aviv University. These nanobatteries should prove useful for various micro devices used for medical, military, and a range of other applications. They are 2-4 years from commercial availability."

FDA Decides Cloned Animals Safe to Eat 323

friedo writes "After five years of research, the Food and Drug Administration has decided that meat and milk from cloned animals is safe to eat. From the article: 'The government believes meat and milk from cattle, swine and goat clones is as safe to eat as the food we eat every day, said Stephen F. Sundlof, director of the FDA Center for Veterinary Medicine. Meat and milk from the offspring of clones is also safe, the agency concluded. Officials said they did not have enough information to decide whether food from sheep clones is safe. If food from clones is indistinguishable, FDA doesn't have the authority to require labels, Sundlof said. Companies trying to distance themselves from cloning must be careful with their wording, he added.'"

NASA Needs Fake Moon Dust 179

crisco writes "NASA's renewed interest in lunar exploration and 'in situ resource utilization,' or ISRU, is driving the need for tons of carefully faked lunar dust and sand for testing purposes: 'We don't have enough real moondust to go around,' says Larry Taylor, director of Planetary Geosciences Institute at the University of Tennessee in Knoxville. To run all the tests, "we need to make a well-qualified lunar simulant.' And not just a few bags will do. 'We need tons of it, mainly for working on technologies for diggers and wheels and machinery on the surface,' adds David S. McKay, chief scientist for astrobiology at the Johnson Space Center (JSC)."

It's OK to keep AIMing 305

fooby12 writes "According to the Univeristy of Toronto instant messaging does not hurt the grammar of the people who use it. From the article: "With 80% of Canadian teenagers using instant messaging and adopting its unique linguistic shorthand, many teachers and parents are concerned about the medium's potential to corrupt kids' grammar. But instant messaging doesn't deserve its bad reputation as a spoiler of syntax, suggests a new study from the University of Toronto.""

Apollo 11 TV Tapes Go Missing 438

Richard W.M. Jones writes "On July 21st 1969, Honeysuckle Creek observatory brought us the first TV pictures of men on the moon. The original signals were recorded on high quality slow-scan TV (SSTV) tapes. What was released to the TV networks was reduced to lower quality commercial TV standards. Unfortunately John Sarkissian of Parkes Observatory Australia reports that 698 of the 700 boxes of original tapes have gone missing [warning: large PDF] from the U.S. National Archives. Even more worryingly, the last place on earth which can actually read these tapes is scheduled to close in October this year. The PDF contains interesting comparisons which show that if all you've seen are the TV pictures from the landing, you really haven't seen the first moon walk in its full glory."

MySpace #1 US Destination Last Week 381

An anonymous reader writes "Hitwise is reporting that MySpace has reached the top, surpassing Yahoo! Mail as the most visited site on the internet for US users. Seeing a 4300% increase in visits in just two short years, this internet sensation has come quite a long ways. From the article: 'To put MySpace's growth in perspective, if we look back to July 2004 myspace.com represented only .1% of all Internet visits. This time last year myspace.com represented 1.9% of all Internet visits. With the week ending July 8, 2006 market share figure of 4.5% of all the US Internet visits.'"
