Astronomers find puzzling dwarf star with complex magnetic fields
Typically, little M-dwarf stars-the most common type of star in the galaxy-are cold, quiet, and dim. Now a team of astronomers led by Edo Berger, a Carnegie-Princeton postdoctoral fellow, found one M-dwarf that doesn't conform.   view more (2007-12-06)

Catalyst-free chemistry makes self-healing materials more practical
A new catalyst-free, self-healing material system developed by researchers at the University of Illinois offers a far less expensive and far more practical way to repair composite materials used in structural applications ranging from airplane fuselages to wind-farm propeller blades.   view more (2007-11-28)

Changing environment organizes genetic structure
What is the fundamental creative force behind life on Earth" It's a question that has vexed mankind for millennia, and thanks to theory and almost a year's worth of number-crunching on a supercomputer, Rice University physicist and bioengineer Michael Deem thinks he has the answer: A changing... view more (2007-11-14)

Satellite methods for monitoring volcanic activity in the Andes Cordillera
The central part of the Andes situated between southern Peru and Chile bears 50 active or potentially volcanoes, spread along a 1500 km-long arc. These volcanic structures mostly rise to between 4000 and 7000 m, are very remote with abrupt slopes and are often cloaked in snow.   view more (2007-10-08)

Brown Researchers Make Major Signal Transduction Discovery
The chemical process known as acetylation plays a central role in cytokine receptor signal transduction - a fundamental biochemical cascade inside cells that controls the activity of antiviral and tumor-suppressing genes.   view more (2007-10-05)

UNC School of Pharmacy researchers create new synthetic heparin
Researchers at the University of North Carolina at Chapel Hill have patented a synthetic version of the drug heparin, called Recomparin, that is less complex chemically and should be easier to produce than previous forms.   view more (2007-09-24)

The importance of gene regulation for common human disease
A new study published in Nature Genetics on Sunday 16 September 2007 show that common, complex diseases are more likely to be due to genetic variation in regions that control activity of genes, rather than in the regions that specify the protein code.   view more (2007-09-17)

Influence of sex and handedness on brain is similar in capuchin monkeys and humans
Capuchin monkeys are playful, inquisitive primates known for their manual dexterity, complex social behavior, and cognitive abilities.   view more (2007-08-30)

Conaway Lab Demonstrates Mechanism by which Transcription Factor Controls Gene Expression
The Conaway Lab - led by Joan Conaway, Ph.D., and Ron Conaway, Ph.D., Investigators - has published findings that shed light on the role of the much-studied transcription factor YY1 in gene expression. Yong Cai, Ph.D., Research Specialist I, and Jingji Jin, Ph.D., Senior Research Associate, are the... view more (2007-08-28)

Researchers pinpoint techniques for better learning
People have incredible amounts to learn throughout their lives, whether it be preparing for a test in middle school or training for a new job late in life. Given that time is often at a premium, being able to efficiently learn new information is important.   view more (2007-08-24)
