Returning from a recent 1,000-mile expedition across Tibet's remote Chang Tang region, Wildlife Conservation Society (WCS) biologist George Schaller reports that the Tibetan antelope -- once the target of rampant poaching -- may be increasing in numbers due to a combination of better enforcement and a growing conservation ethic in local communities.

Researchers hoping to learn why organisms tend to live longer if their intake of calories is restricted have made a startling discovery – in fruit flies, just the smell of food can have a negative effect on longevity.

A protein that causes coral to glow is helping researchers at the University of Maryland School of Medicine to light up brain cells that are critical for the proper functioning of the central nervous system. This fluorescent marker protein may shed light on brain cell defects believed to play a role in various neurological diseases. The researchers describe how this marker works in mice in the December 20, 2006, issue of The Journal of Neuroscience.

Scientists from the University of East Anglia have discovered exactly what makes the seaside smell like the seaside – and bottled it!

Just over a decade ago, biologists isolated a unique protein from jellyfish that could be inserted into other organisms—from E. coli to pigs—and cause them to radiate a brilliant green color. This green fluorescent protein (GFP) has allowed biologists to make many new discoveries regarding how living cells function. But one kingdom of life—plants—has presented special challenges to GFP detection: plants harbor tough cell walls and enormous subcellular structures that interfere with visualization, and their natural green pigments can mask the luminescent qualities of GFP.

Brown University researchers are creating a technology that will allow doctors and scientists to do the seemingly impossible: See inside living humans and animals and watch their bones move in 3-D as they run, fly, jump, swim and slither.

For the first time, scientists have observed DNA being damaged by ultraviolet (UV) light.

An invasive whitefly has developed mutualistic relationships with the plant viruses it transmits and is able to increase its population much faster on virus-infected plants than on healthy plants, whereas its indigenous counterpart is unable to do so, according to the new research carried out at Zhejiang University and Chinese Academy of Agricultural Sciences, China.

Parasite-carrying bloodsucking leeches may be delivering a one-two punch to newts, according to biologists, who say the discovery may provide clues to disease outbreaks in amphibians.
