Though viewed as sources of potential green energy, their construction also poses a significant environmental cost

Using computer models of the warming process, the researchers simulated the effects of PETM ocean warming on sediments that may have contained methane hydrate

Jim Evans and collaborators study Utah's Carmel Formation

Researchers found that the bulk soil on Mars, across regional scales the size of the U.S. or larger, likely contains iron sulfates bearing chemically bound water, which typically result in acidic brines

Getting clean water to communities in parched areas of the planet remains an ongoing challenge. Recent developments that harvest water from air have been proposed as a solution

“This will give us a better understanding of how life evolved”

Rice University technique could aid agriculture, wastewater, greenhouse gas studies

Rutgers and Harvard scientists lay out strategy for investigating societal consequences

Kyoto University study reveals quake fault secrets, implications for early warning

The Atmospheric Tomography, or ATom, mission is the first to survey the atmosphere over the oceans

Hot, rocky planets may change their composition if rock components vaporize in steam atmospheres that escape to space

The scientists studied sediments towering over 400 meters high from North-Eastern Greenland. Carbon isotope curves suggest that the prevalent seed ferns and conifers were replaced by spore plants in the space of a few millennia
