UI anthropologist, colleagues discover remains of earliest giant panda

... to refine. Our new discovery shows the great time depth of this unique bamboo-eating specialization in pandas. Thus, pandas have been ‘uniquely pandas’ for many millions of years says Ciochon.” Ciochon says that the find further helps establish conditions that existed in the region during the varying c...

They zoomed in on kinases, extremely well studied enzymes, which control every aspect of eukaryotic cell biology and are important cancer drug targets. They control the activity of proteins and small molecules by attaching...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

Fish growth changes enhanced by climate change

...mental conditions ?faster growth in waters above a depth of 250 metres and slower rates of growth below 1,000 metres,?says lead author, Dr Ron Thresher. “These observations suggest that global climate change has enhanced some elements of productivity of shallow-water stocks but at the same time reduced ...

Dig deeper to find Martian life

We have found that this suspected frozen sea in Elysium represents one of the most exciting targets for landing a probe, as the long-term survival of cells here is better than underground in icy rock....

NASA snow data helps maintain nation's largest, oldest bison herd

...The snowpack model provides daily maps of snowpack depth and density throughout the Yellowstone landscape, in near-real time. It uses data from NASA's Landsat satellite to describe how the snowpack is influenced by patterns of vegetation, geothermal features, and wind. Daily measurements of precipitation a...

Study: Living coral reefs provide better protection from tsunami waves

...ers had to be considered one by one: the width and depth of the reef; the roughness of its surface; the size of the lagoon behind it; and the slope of the coast beyond. And the overarching element was the wave itself and its interaction with all these obstacles. Eventually, Kunkel found a set of equations ...
