Curved carbon for electronics of the future
A new scientific discovery could have profound implications for nanoelectronic components.

Culprit found for increased stroke injury with diabetes
Strokes that involve intracerebral hemorrhage (bleeding in the brain) are especially deadly, and there are no effective treatments to control such bleeding.

Faster development might have its costs
Fast development is often perceived as an advantage. However, research conducted on salamanders at the University of Haifa and the University of California, found that the acceleration of developmental rates increases mortality.

Researchers find smoking gun of world's biggest extinction
Researchers at the University of Calgary believe they have discovered evidence to support massive volcanic eruptions burnt significant volumes of coal, producing ash clouds that had broad impact on global oceans.

Unexpected find opens up new front in effort to stop HIV
HIV adapts in a surprising way to survive and thrive in its hiding spot within the human immune system, scientists have learned.

Nailing down a crucial plant signaling system
Plant biologists have discovered the last major element of the series of chemical signals that one class of plant hormones, called brassinosteroids, send from a protein on the surface of a plant cell to the cell's nucleus.

Climate change threatens many tree species, say Hebrew U. researchers
Global warming is already affecting the earth in a variety of ways that demand our attention.

Uncovering the trail behind growing too old, too soon
Scientists from A*STAR's Institute of Medical Biology in Singapore and the University of Hong Kong's Department of Medicine have produced the world's first human cell model of progeria, a disease resulting in severe premature aging in one in four to eight million children worldwide.

Fighting the fight for healthy teeth
It is known that teeth can protect themselves, to some extent, from attack by bacteria but that inflammation within a tooth can be damaging and, in extreme cases, lead to abscess or death of the tooth.

Genetic sequencing alone doesn't offer a true picture of human disease
Despite what you might have heard, genetic sequencing alone is not enough to understand human disease.

New study suggests global pacts like REDD ignore primary causes of destruction of forests
A new study issued today by some of the world's top experts on forest governance finds fault with a spate of international accords, and helps explain their failure to stop rampant destruction of the world's most vulnerable forests.

Columbia University researchers use nanoscale transistors to study single-molecule interactions
A Columbia University team that includes researchers from Engineering School and the Physics and Chemistry departments, has figured out a way to study single-molecule interactions on very short time scales using nanoscale transistors.
