The 160-mile download diet: Local file-sharing drastically cuts network load (PhysOrg.com) -- Ever since Bram Cohen invented BitTorrent, Web traffic has never been the same. Whether that's a good thing or a bad thing, however, is a matter of debate. Friendster supports applications for rival sites (AP) -- Friendster, an early online social network that has faded in the United States but remains strong in Asia, has begun letting programmers create photo-sharing applications and other programs that work on Friendster as well as rival sites. Calculators okay in math class, if students know the facts first Calculators are useful tools in elementary mathematics classes, if students already have some basic skills, new research has found. The findings shed light on the debate about whether and when calculators should be used in the classroom. California fines 18 hospitals for shoddy care (AP) -- Eighteen hospitals in California were fined for state health code violations in which patients received shoddy care that in some cases led to deaths. Getting to the root of the matter Like most things that exist underground, plant roots are out-of-sight and easily forgotten, but while flowers, leaves, and other aboveground plant parts are more familiar, plant roots are equally deserving of our appreciation. Beneath every towering tree, tasty crop, and dazzling ornamental lies a root system that makes it all possible. Roots provide anchor and support for plants, extract water and nutrients from soil, and reduce soil erosion. Roots also play an important role in soil carbon cycling and the global carbon balance. Caltech researchers awarded $10M for molecular programming project The National Science Foundation's Expeditions in Computing program has awarded $10 million to the Molecular Programming Project, a collaborative effort by researchers at the California Institute of Technology and the University of Washington to establish a fundamental approach to the design of complex molecular and chemical systems based on the principles of computer science. IBM Research Unleashes Powerful Speech Software (PhysOrg.com) -- IBM today announced the availability of state-of-the-art speech recognition software to clients and partners exploring the development of real-world consumer and business solutions. Switching it up: How memory deals with a change in plans You're about to leave work at the end of the day when your cell phone rings: it's your spouse, asking that you pick up a gallon of milk on the way home. Before you head out the door, though, your spouse calls again and asks you to stop by the hardware store too. Based on your knowledge of the area and rush-hour traffic, you decide to get the milk first and the toilet plunger second. But whoops! The phone rings again. This time, it's your boss, asking you to work late. That means another change of plans. Researchers Study Facial Structures, Brain Abnormalities to Reveal Formula for Earlier Detection of Autism (PhysOrg.com) -- Recently, Harvard researchers reported that children with autism have a wide range of genetic defects, making it nearly impossible to develop a simple genetic test to identify the disorder. Researchers discover technology that silences genes Mount Sinai researchers have developed a new gene silencing technology that could be used to target genes that can lead to the development of certain diseases. This technology could pave the way for preventing diseases where gene dysfunction plays a role. ... |
