Last year, for the first time, scientists used an unmanned aerial vehicle, or UAV, to study killer whales from above. In an article published this month in the Journal of Unmanned Vehicle Systems, scientists describe how they configured their UAV, turning it into a precision scientific instrument. The international team of scientists from NOAA Fisheries […]
New research confirms that the land under the Chesapeake Bay is sinking rapidly and projects that Washington, D.C., could drop by six or more inches in the next century—adding to the problems of sea-level rise. This falling land will exacerbate the flooding that the nation’s capital faces from rising ocean waters due to a warming […]
The original Americans came from Siberia in a single wave no more than 23,000 years ago, at the height of the last Ice Age, and apparently hung out in the north – perhaps for thousands of years – before spreading in two distinct populations throughout North and South America, according to a new genomic analysis.

The mountains likely formed no more than 100 million years ago — mere youngsters relative to the 4.56-billion-year age of the solar […]
