New Insights Into The Evolution Of The Human Genome
Researchers have created the first evolutionary history of the duplications in the human genome that are partly responsible for both disease and recent genetic innovations. This work marks a significant step toward a better understanding of what genomic changes paved the way for modern humans, when these duplications occurred and what the associated costs are - in terms of susceptibility to disease-causing genetic mutations. The Great Race
Website for the centennial celebration in 2008 of the 1908 New York to Paris automobile race. "In a re-run of that milestone event, the 2008 Great Race will depart New York City on 30 May 2008 and travel 35,000 km (22,000 miles), to Paris, France and finish on 2 August."Features background about the original race, and details about the 2008 race, including a listing of race participants and vehicles. From the race promoters. Greasing Interferon's Gears May Pave Way To Greater Therapeutic Benefi
Interferon -- a critical protein that mediates the body's defense against a wide variety of infectious agents and tumors -- may soon have greater therapeutic value as the result of a new study by researchers at Washington University School of Medicine in St. Louis. Nearly Unbreakable: Novel Nanoscale Construction Principle Prevents Bo
Max Planck Scientists discover a novel construction principle at the nanoscale which prevents bones from breaking at excessive force. Overexposure to credit default swaps contributed to financial meltdown
Overexposure to credit default swaps (CDS) -- a market-traded form of investment insurance -- are believed to have contributed to last year's financial meltdown. Trying to understand how CDS prices are determined, a team of researchers concludes that earnings have a major impact and in turn, CDS prices can seriously affect the economy. When earnings drop, CDS spreads rise. Learning How Nature Splits Water
An international team led by scientists from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) pieced together high-resolution (approximately 0.15 Ångstrom) structures of a Mn4Ca cluster found in a photosynthetic protein complex. Their work could help researchers synthesize molecules that mimic this catalyst, which is a central focus in the push to develop clean energy technologies that rely on sunlight to split water and form hydrogen to feed fuel cells or other non-polluting power sources. Plasticine, Salt, and Melting Snow
Why do they grit the roads with rock salt in winter? What does the salt do to the water to reduce ice on the roads? Is this somehow related to how salt affects the boiling point of water? Keywords to search for: colligative properties, boiling, freezing, ions, solutions, solvent, Raoult’s lawMeanwhile, I’ll let Plasticine models [...] Murder on MySpace
When Daniel Varo, who lived his life on the web, is killed by a shot to the back of the head, his death plays out online, too. By Noah Shachtman from Wired magazine. Plus: Epilogue: A Reporter's Notebook Cilia: Small Organelles, Big Decisions
Scientists say they have figured out how human and all animal cells tune in to a key signal, one that literally transmits the instructions that shape their final bodies. It turns out the cells assemble their own little radio antenna on their surfaces to help them relay the proper signal to the developmental proteins "listening"on the inside of the cell. Technology For Successful Aging Shown At White House Conference
A pill box that keeps track of the medications taken and knows when the user is nearby is one of a handful of innovative devices Oregon Health &Science University researchers are developing to unobtrusively monitor how seniors go about their day-to-day lives in their homes. The devices are the work of OHSU's Oregon Roybal Center for Aging &Technology, which is studying and developing technology to assess how seniors function in their home environment.
