AMES, Iowa — An international team of scientists has released data indicating that greenhouse gas uptake by continents is less than previously thought because of methane emissions from freshwater areas.
John Downing, an Iowa State University pro…
(Santa Barbara, Calif.) — — Calling the results “extremely surprising,” researchers from the University of California, Santa Barbara and Texas A&M University report that methane gas concentrations in the Gulf of Mexico have returned to near n…
This new infrared image of the Lagoon Nebula was captured as part of a five-year study of the Milky Way using ESO’s VISTA telescope at the Paranal Observatory in Chile. This is a small piece of a much larger image of the region surrounding the…
PORTLAND, Ore. December 21, 2010. “When I first picked up the cub, she was biting my hand,” explains wildlife biologist Bruce Marcot. He was trying to calm the squirming cub while its sedated mother slept nearby.
In the snowy spring of 2009, Por…
ANN ARBOR, Mich.—New observations by University of Michigan astronomers add weight to the theory that the most massive stars in the universe could form essentially anywhere, including in near isolation; they don’t need a large stellar cluster…
Researchers from the University of Santiago de Compostela (USC) have analysed levels of radon, a natural radioactive gas, in 58 secondary schools in Galicia. The results show that 34% of these schools exceed the limit of 400 Bequerels/m3 recom…
MANHATTAN, KAN. — A Kansas State University professor is part of a national research team that discovered that streams and rivers produce three times more greenhouse gas emissions than estimated by the Intergovernmental Panel on Climate Change.

EAST LANSING, Mich. — Nitrous oxide, a potent greenhouse gas, has increased by more than 20 percent over the last century, and nitrogen in waterways is fueling part of that growth, according to a Michigan State University study.
Based on this n…
In the developing world, reducing greenhouse gas emissions is often seen as being in conflict with alleviating poverty, since improving the standard of living is usually associated with increased energy use.
A clean energy development initiative i…
Following a study of what is in effect a miniature galaxy buried inside a normal-sized one — like a Russian doll — astronomers using a CSIRO telescope have concluded that massive black holes are more powerful than we thought.
An international t…
Astronomers find cosmic dust annoying when it blocks their view of the heavens, but without it the universe would be devoid of stars. Cosmic dust is the indispensable ingredient for making stars and for understanding how primordial diffuse gas…
COLLEGE PARK, Md. — One of the biggest comet findings coming out of the amazing images and data taken by the University of Maryland-led EPOXI mission as it zipped past comet Hartley 2 last week is that dry ice is the ‘jet’ fuel for this comet…
