In work that could one day help prevent millions of dollars in economic losses for seaside communities, MIT chemists have demonstrated how tiny marine organisms likely produce the red tide toxin that periodically shuts down U.S. beaches and shellfish beds

Biologists at Harvard University have identified the ancient fossilized remains of a pollen-bearing bee as the first hint of orchids in the fossil record, a find they say suggests orchids are old enough to have co-existed with dinosaurs.

Scientists have suspected that the three known domains of life -- eukaryotes, bacteria, and archaea -- branched off and went their separate ways around three billion years ago. But pinning down the time of that split has been an elusive task.

A scientist from the University of Aberdeen is leading a team of international researchers whose work will continue our understanding of life in the deepest oceans, and contribute to the global Census of Marine Life.

Researchers have found that New Caledonian crows--which are known to make complex food-getting tools in the wild--can also spontaneously use one tool on another to get a snack.

gene mutation that appears to be responsible for changing relatively mild forms of the West Nile virus into a highly virulent and deadly disease in American crows has been identified by a team of scientists led by a researcher at the University of Califor
