A new study exploring the
growing worldwide problem of nitrogen pollution, from soils to the sea, shows that global ratios of nitrogen and carbon in the environment are inexorably linked, a finding that may lead to new strategies to help mitigate regional problems ranging from contaminated waterways to human health.

New results from a research expedition in Antarctic waters may provide critical clues to understanding one of the most dramatic periods of climate change in Earth's history.
Some 53 million years ago, Antarctica was a warm, sub-tropical environment. During this same period, known as the "greenhouse" or "hothouse" world, atmospheric carbon dioxide levels exceeded those of today by ten times.
Then suddenly, Antarctica's lush environment transitioned into its ...

Contrary to popular belief, aphids are not just sap-sucking, plant-destroying enemies of agriculture. In fact, these pests are genetic pioneers that evolved two unique traits, according to a study that appears in the April 30 issue of the journal Science.
First, aphids are, so far, the only animal known to produce essential pigments known as carotenoids. The aphid's pigment-producing ability is unique to the animal kingdom. Other animals, including humans, that need ...
