Songbirds offer clues to highly practiced motor skills in humans
December 31, 2007 11:22 PM -

San Francisco - The melodious sound of a songbird may appear effortless, but his elocutions are actually the result of rigorous training undergone in youth and maintained throughout adulthood. His tune has virtually “crystallized” by maturity. The same control is seen in the motor performance of top athletes and musicians. Yet, subtle variations in highly practiced skills persist in both songbirds and humans. Now, scientists think they know why.

PITTSBURGH - The tiny nation of Bhutan, whose national credo is "Gross National Happiness," has launched an innovative postage stamps to support its economic development-and to preserve its pristine Himalayan environment-at the same time.

When affixed to a larger envelop, the CD stamp can be used as postage.

The United Nations Climate Change Conference in Bali, Indonesia, early this month received criticism from some for failing to produce a stronger international plan to address greenhouse gas emissions once the Kyoto Protocol expires in 2012. “We said we needed a roadmap,” Tony Juniper of Friends of the Earth told the BBC, “but this conference has failed to give us a clear destination.” To offset further delay, some countries and many local governments have taken the lead and committed to hefty carbon-reduction schemes ahead of a formalized international plan.

NOAA: 2007 a Top Ten Warm Year for U.S. and Globe
December 30, 2007 11:52 AM - NOAA

The year 2007 is on pace to become one of the 10 warmest years for the contiguous U.S., since national records began in 1895, according to preliminary data from NOAA’s National Climatic Data Center in Asheville, N.C. The year was marked by exceptional drought in the U.S. Southeast and the West, which helped fuel another extremely active wildfire season. The year also brought outbreaks of cold air, and killer heat waves and floods. Meanwhile, the global surface temperature for 2007 is expected to be fifth warmest since records began in 1880. Preliminary data will be updated in early January to reflect the final three weeks of December and is not considered final until a full analysis is complete next spring.

Study maps life in extreme environments
December 29, 2007 11:13 AM - New York University

A team of biologists have developed a model mapping the control circuit governing a whole free living organism. This is an important milestone for the new field of systems biology and will allow the researchers to model how the organism adapts over time in response to its environment. This study marks the first time researchers have accurately predicted a cell’s dynamics at the genome scale (for most of the thousands of components in the cell). The findings, which are based on a study of Halobacterium salinarum, a free-living microbe that lives in hyper-extreme environments, appear in the latest issue of the journal Cell.
