As the U.S. Southwest grew warmer from 18,700 to 10,000 years ago, juniper trees vanished from what is now the Mojave Desert, robbing packrats of their favorite food. Now, University of Utah…

If you're a Muslim and you're worried that debating your NCAA March Madness championship tie-breaker scenarios at work will cause you to miss a prayer time ... well, okay, you're not doing that…

A small, pilot study in 50 people in Japan suggests that eating two and a half ounces of broccoli sprouts daily for two months may confer some protection against a rampant stomach bug that causes…

I came across a blog today, written by a female scientist (apparently - it's an anonymous blog and that's okay, if Obama's teleprompter can have a blog I suppose anyone sentient can also, but…

Please be warned. The only link to science is really the single word "ornithologist". Unless you are studying humour, that is. For The Birds, a very short story worth reading.

A new study in mice shows that a dual therapy can lead to generation of new blood vessels and improved cardiac function following a heart attack. The research, published by Cell Press in the April…

Scientists have discovered that growing mouse skin cells in spheres can lead to generation of cells with properties of cancer stem cells, even without genetic manipulation of stem cell genes. This…

A new study finds previously unidentified fibrocartilage-forming progenitor cells in degenerating, diseased human cartilage, but not in cartilage from healthy joints. The research, published by Cell…

A new study has identified a potential strategy for removing the abnormal protein that causes Huntington's disease (HD) from brain cells, which could slow the progression of the devastating…

A new study in the April 3rd issue of the journal Cell, a Cell Press publication, helps to explain why people who carry mutations in a gene known as Nurr1 develop a rare, inherited form of Parkinson…

Special proteins known as prions, which are perhaps best known as the agents of mad cow and other neurodegenerative diseases, can also serve as an important source of beneficial variation in nature,…

Scientists have discovered a naturally occurring compound that triggers a plant's immune system, thereby protecting the plant from a secondary bacterial infection. The patent-pending discovery could…

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have created a Robot Scientist which the researchers believe is the first machine to have independently…

LA JOLLA, Calif., April 3, 2009 -- Investigators at Burnham Institute for Medical Research (Burnham) have demonstrated that attacks on the mitochondrial protein Drp1 by the free radical nitric oxide…

MADISON — If you've ever been sleep-deprived, you know the feeling that your brain is full of wool. Now, a study published in the April 3 edition of the journal Science has molecular and structural…

If Isaac Newton had access to a supercomputer, he'd have had it watch apples fall – and let it figure out the physical matters. But the computer would have needed to run an algorithm, just developed…

Using the digital mind that guides their self-repairing robot, researchers at Cornell University have created a computer program that uses raw observational data to tease out fundamental physical…

CAMBRIDGE, Mass--For the first time, MIT researchers have shown they can genetically engineer viruses to build both the positively and negatively charged ends of a lithium-ion battery. The new virus…

St. Louis, March 30, 2009 —A new theory about sleep's benefits for the brain gets a boost from fruit flies in this week's Science. Researchers at Washington University School of Medicine in St. Louis…

HOUSTON (April 3, 2009) – A particular nuclear hormone receptor called DAF-12 and molecules called microRNAs in the let-7 family form a molecular switch that encourages cells in the larvae of a model…
