In the 21st century, state-of-the-art anti-aging technologies may extend human lifespans at an unprecedented rate, bringing with them a host of social and economic challenges, says biologist Shripad Tuljapurkar of Stanford University.

In his recent State of the Union speech President Bush said technology is the best way to break the nation's addiction to oil. The U.S. Department of Energy Joint Genome Institute (DOE JGI) is directing the technology of DNA sequencing to scan the environment for processes that will lead to cheaper and easier to produce biofuels.

Researchers from The University of Texas at Austin studying electric fish have gained new insight into how memory is stored at the level of neurons.

Researchers are enlisting seals, sea lions, tunas, and sharks to serve as ocean sensors, outfitting these top predators with electronic tags that gather detailed reports on oceanographic conditions and, in many cases, transmit the data via satellite. The data are proving useful to both biologists and oceanographers, yielding new information about the migrations and behavior of the animals and about the environments in which they live.

The closest encounter most wildlife biologists have with wolverines in the Pacific Northwest is seeing a set of the animal's tracks in the snow. But wildlife biologist Keith Aubry recently got the call he had eagerly anticipated for several weeks.

The world has passed "peak fish" and fishermen's nets will be hauling in ever diminishing loads unless there's political action to stem the global tide of over fishing, says a fisheries expert based at the University of British Columbia. Dr. Daniel Pauly says the crisis in the world's fisheries is less about scientific proof than about attitude and political will.

Human eggs rely on handmaidens. Called granulosa cells, they surround eggs and deliver nutrients and hormones. Without granulosa cells, eggs cannot mature and be successfully fertilized.

The medication tetrabenazine cut down involuntary movement in patients with Huntington's disease on average by about 25 percent, with many patients experiencing a greater improvement, according to a study in the February 14 issue of the journal Neurology.

Researchers have identified a key signaling molecule in the brain that appears to trigger the brain to "learn" a craving for cocaine. Their finding could offer an important target for drugs to treat addiction by short-circuiting that adaptive process.

With no known enemies in North America, two types of invasive vines are growing rampant in forests and fields, threatening reforestation, fragile butterfly populations and bird habitats.

The University of Liverpool is offering a new form of equine cataract removal surgery on a routine basis, which could save the sight of thousands of horses.
