Velociraptor was just a scary turkey, say scientists
Yes, it's a Hobbit. The debate that has divided science is solved at last (sort of)
Velociraptor, the fearsome dinosaur made famous in the Jurassic Park films, had feathers and probably more closely resembled a big turkey than the killer screen dinosaur, scientists have discovered.

Arctic sea ice minimum shatters all-time record low, report University of Colorado scientists
A herd of fossilised infant dinosaurs killed in a volcanic mudflow are found in China.
Brain system serves as 'remote control' for fat metabolism
Scientists from the University of Colorado at Boulder's National Snow and Ice Data Center said today that the extent of Arctic sea ice appears to have reached its minimum for 2007 on Sept. 16, shattering all previous lows since satellite record-keeping began nearly 30 years ago.
Britain lifts control zone around suspected foot and mouth farm
A system in the brain already known to regulate food intake also serves as a direct remote control for the way fat is stored and metabolized in the body, say University of Cincinnati (UC) researchers.
Key to longer life (in flies) lies in just 14 brain cells
Britain lifted a temporary control zone around a farm close to the central city of Birmingham on Thursday after tests for foot and mouth disease proved negative, the agriculture ministry said.

Two years ago, Brown University researchers discovered something startling: Decrease the activity of the cancer-suppressing protein p53 and you can make fruit flies live significantly longer.
Scientists launch deep-sea scientific drilling program to study volatile earthquake zone
(AP) -- Business software maker Oracle Corp. overcame the recent economic turbulence that raised recession anxieties to deliver a fiscal first-quarter performance that topped analyst expectations.
Mystery Boy in Iron Coffin Identified
Today, the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) gets underway, with the Japanese drilling vessel Chikyu departing from Shingu Port with scientists aboard, all ready to log, drill, sample, and install monitoring instrumentation in one of the most active earthquake zones on Earth. The vessel's launch starts the first of a series of scientific drilling expeditions that will retrieve geological samples and provide scientific data from the Nankai Trough fault zone for the first time.
SEC Subpoenas Jobs in Stock Options Case
(AP) -- Researchers have solved the mystery of the boy in the iron coffin. The cast-iron coffin was discovered by utility workers in Washington two years ago. Smithsonian scientists led by forensic anthropologist Doug Owsley set about trying to determine who was buried in it, so the body could be placed in a new, properly marked grave.
(AP) -- Apple Inc. CEO Steve Jobs has been subpoenaed by the U.S. Securities and Exchange Commission to give a deposition in a stock-options backdating case against Apple's former general counsel, a person familiar with the case told The Associated Press Thursday.

Mystery boy in iron coffin identified
AP - For American parents looking for donor sperm to produce blond, blue-eyed Scandinavian babies, the search just got a little trickier. A ban on sperm from all European countries with exposure to mad cow disease means U.S. sperm banks are running low.

Smithsonian scientists led by forensic anthropologist Doug Owsley set about trying to determine who was buried in it, so the body could be placed in a new, properly marked grave.
Antibiotic Resistance: Drug Resistance Gene Has Spread From East Coast To Midwest Bacteria
Reuters - A U.N.
tribunal set a boundary on Thursday for Guyana and Suriname in
a dispute over an oil basin, a decision welcomed by Canada's
CGX Energy which had operated there until Surinamese gunboats
expelled the company in 2000.
Brain's Messengers Could Be Regulated, Study Suggests
A resistance gene that allows bacteria to beat an important class of antibiotics has started to appear in microorganisms taken from Midwestern patients, according to researchers. Less than a decade ago, scientists first noticed the BlaKPC gene in bacteria taken from East Coast patients. Bacteria with an active copy of the gene can defeat carbapenems, antibiotics reserved for use in the most critically ill patients.
Increased Bering Sea Ice Explains Prehistoric Fur Seal Rookeries
Tiny, spontaneous releases of the brain's primary chemical messengers can be regulated, potentially giving scientists unprecedented control over how the brain is wired. The work could lead to a better understanding of neurological diseases like schizophrenia. Sputtering electrical activity -- like a firecracker's leftover sparks after a big bang -- was long considered inconsequential background noise compared with the main cell-to-cell interactions underlying thought and memory. But researchers found that the miniscule events that follow a burst of electrical and chemical activity among neurons are far more important that previously thought.
Intriguing Structures On The Surface Of Fat Cells
The Bering Sea provides critical habitat for many species of marine mammals, including seals, sea lions and whales. The predictable formation and movement of sea ice is a defining feature of this habitat, although new evidence suggests that only a few thousand years ago, during a period of cold climate known as the "Neoglacial," much more ice filled the Bering Sea and stayed around longer.
Structure Of Enzyme In Unusual Virus Identified
The surface of fat cells contains many small pockets called caveolae (because they look like caves in an electron microscope). Although their role is not clear, Paul F. Pilch and colleagues review current knowledge about caveolae and conclude that one of their major functions is to regulate the movement and production of fats in fat cells. Caveolae may also help the hormone insulin bind to fat cells, but this is controversial. Insulin binds to protein receptors on the surface of a fat cell, which activates proteins inside the cell that help lower the amount of sugar in the blood and store fats.
Stuck With A Weak Mate? Species Compensate To Increase Viable Offspring
Biologists have determined the three-dimensional structure of an unusual viral enzyme that is required in the assembly of new viruses. Learning the fundamental mechanisms for how this process works may later enable scientists to develop drugs that inhibit certain viral infections, according to the researchers.
New research that crosses several species boundaries shows that when animals must choose less-than-preferred (to them) mates, females and males apparently have ways to compensate that increase the chance their offspring will survive.
