Photosynthesis leaves behind a unique calling card, a chemical signature that is spelled out with stable oxygen isotopes, according to a new study in Science. The findings suggest that similar isotopic signatures could exist ...
At just a bit over crop duster height, University of Michigan researchers are flying through a 50-square-mile hotspot of the greenhouse gas methane over the U.S. Southwest.
With more than a thousand confirmed planets outside of our solar system, astronomers are attempting to identify the atmospheres of these distant bodies to determine if they could possibly host life.
New work from Carnegie's Russell Hemley and Ivan Naumov hones in on the physics underlying the recently discovered fact that some metals stop being metallic under pressure. Their work is published in Physical Review Letters.
A new NASA initiative is embracing a team approach to the problem of finding life on planets around other stars.
Scientists have discovered that stunted growth can be a genetic response to ocean acidification, enabling some sea creatures to survive high carbon dioxide levels, both in the future and during past mass extinctions.
Tropical Pacific climate variations and their global weather impacts may be predicted much further in advance than previously thought, according to research by an international team of climate scientists from the USA, Australia, ...
A spacecraft that carries a sensor built at the University of Michigan is about to crash into the planet closest to the sun—just as NASA intended.
Scientists have rediscovered a mostly intact World War II-era U.S. aircraft carrier used in atomic bomb tests and then sunk at a secret location off the Northern California coast decades ago.
A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered ...
