Bizarre reptile challenges notion of crocodiles as 'living fossils' (December 10, 2010) -- We all know that crocodiles are reptiles with long snouts, conical teeth, strong jaws and long tails. But, new discoveries show we don't know what we thought we knew. Rather, some crocodiles possessed a dazzling array of adaptations that resulted in unique and sometimes bizarre anatomy, including blunt, pug-nosed snouts, pudgy bodies and short tails. ... > full story
Trio of drugs may combat 'triple negative' breast cancer (December 10, 2010) -- Working with cell cultures and mouse models, researchers have tested a cocktail of three drugs that holds promise for treating so-called triple negative breast cancers. ... > full story
WISE sees an explosion of infrared light (December 10, 2010) -- A circular rainbow appears like a halo around an exploded star in a new view of the IC 443 nebula from NASA's Wide-field Infrared Survey Explorer, or WISE. When massive stars die, they explode in tremendous blasts, called supernovae, which send out shock waves. The shock waves sweep up and heat surrounding gas and dust, creating supernova remnants like the one pictured in the new image. The supernova in IC 443 happened somewhere between 5,000 and 10,000 years ago. ... > full story
Immune system changes linked to inflammatory bowel disease revealed (December 10, 2010) -- Scientists have discovered some of the key molecular events in the immune system that contribute to inflammatory bowel disease. ... > full story
Details of microbe's extraordinary maintenance and repair system revealed (December 10, 2010) -- Scientists have discovered how a network of repair proteins enables bacteria to prioritize the repair of the most heavily used regions of the DNA molecules that carry the instructions necessary for living cells to function. ... > full story
Boxing is risky business for the brain (December 10, 2010) -- Up to 20% of professional boxers develop neuropsychiatric sequelae. But which acute complications and which late sequelae can boxers expect throughout the course of their career? ... > full story
Unraveling Alzheimer's: Simple small molecules could untangle complex disease (December 10, 2010) -- New molecular tools show promise for "cleansing" the brain of amyloid plaques, implicated in Alzheimer's disease. ... > full story
There's a new 'officer' in the infection control army (December 10, 2010) -- Scientists have identified a previously unrecognized step in the activation of infection-fighting white blood cells, the main immunity troops in the body's war on bacteria, viruses and foreign proteins. ... > full story
Odyssey orbiter nears Martian longevity record (December 10, 2010) -- By the middle of next week, NASA's Mars Odyssey orbiter will have worked longer at Mars than any other spacecraft in history. Odyssey made its most famous discovery -- evidence for copious water ice just below the dry surface of Mars -- during its first few months, and it finished its radiation-safety check for future astronauts before the end of its prime mission in 2004. The bonus years of extended missions since then have enabled many accomplishments that would not have been possible otherwise. ... > full story
Doctors don't need to fear red heads (December 10, 2010) -- A new study confirms that there is no need for doctors to fear red heads. The research concludes that, contrary to popular belief, people with red hair do not bleed any more than other patients. ... > full story
35,000 new species ‘sitting in cupboards’ (December 10, 2010) -- Of the estimated 70,000 species of flowering plants yet to be described by scientists, more than half may already have been collected but are lying unknown and unrecognized in collections around the world, a new study suggests. ... > full story
Twin study helps scientists link relationship among ADHD, reading, math (December 10, 2010) -- Children with ADHD can sometimes have more difficulties on math and reading tests compared to their peers. A new study used identical and fraternal twins to look at the genetic and environmental influences underlying ADHD behaviors, reading and math skills in children in an attempt to better understand the relationship among them. ... > full story
