CHICAGO – How did the universe begin? How will it end? Do other universes exist? Everyone at some time or another ponders these questions. Generations of researchers have brought us to our current point of understanding, but our picture of the universe has changed more in the past decade or so than it did in [...]

State of the steric sea level rise, 1955-2003
Based on a detailed analysis of ocean vertical temperature profiles for the 1955-2008 period, Sydney Levitus, lead author, talks about the change of global average sea level induced by the observed warming of the world ocean during the past 53 years. The warming of the world ocean is consistent with the amount of warming expected [...]

NOAA Science at AAAS – Research so far on global warming and Atlantic hurricanes indicates: It is premature to conclude that human activity–particularly greenhouse warming–has had a detectable impact on Atlantic hurricanes, and Model simulations indicate that 21st century greenhouse warming may lead to greater numbers of very intense Atlantic hurricanes and higher hurricane rainfall [...]
When fish farms are built along the coast, where does the waste go?
posted in Animals, Earth, HeadlinesStanford researchers help predict where the ‘icky’ stuff — fish urine, fecal matter and uneaten feed — will end up; Research is finding that the wastes are carried greater distances that previously assumed If you are a fish eater, it’s likely that the salmon you had for dinner was not caught in the wild, but [...]
CHICAGO—The global travel logs of greenhouse gases are based on atmospheric sampling locations sprinkled over the Earth and short towers that measure the uptake or release of carbon from a small patch of forest. But those measurements don’t agree with current computer models of how plants and soils behave. A University of Michigan researcher is [...]
Chionodraco hamatus, an Antarctic ice fish, can withstand temperatures that freeze the blood of all other fish types. This finger-lengthed juvenile was photographed in 2008.

Color-composite image of the Carina Nebula, revealing exquisite details in the stars and dust of the region. Several well known astronomical objects can be seen in this wide field image: to the bottom left of the image is one of the most impressive binary stars in the Universe, Eta Carinae, with the famous Keyhole Nebula [...]

Aerosols are fine [...]
The dynamics of rivers and streams can be more clearly identified using new laser-guided mapping technology, or lidar. This figure shows a segment of Maine’s Sheepscot River in a traditional digital topographic contour map (a); a lidar map (b); and the identification of Atlantic salmon spawning habitat (c). Airborne lidar mapping provides far greater resolution [...]
