Quakes recorded for the first time inside Greenland's biggest frozen river, the Northeast Greenland Ice Stream, suggest this river and others switch between moving jerkily and flowing like honey.

Scientists report the detection of amino acids, polycyclic aromatic hydrocarbons, ammonia and other compounds, as well as a variety of salts, including sodium carbonates, phosphates, sulfates, and chlorides, in the Bennu samples.

"These stringent rules make organic one of the most trustworthy labels on the market today"

The weathering of rocks in the Canadian Rockies is accelerating with rising temperatures, creating a feedback loop that is set to dump even more carbon dioxide into the atmosphere.

Researchers at the University of Texas at El Paso (UTEP) have made a major breakthrough in agricultural biotechnology, focusing on the use of

Earth planning date: Monday, Oct. 7, 2024 After successfully completing investigations within Gediz Vallis, Curiosity is back on the road through the Mg-sulfate (magnesium sulfate) bearing unit. The terrain under our wheels is a familiar collection of broken up blocks, and we're keeping our rover eyes on the more distant stratigraphy and the deposits within […]

Seasonal variations with alternating dry and rainy seasons and fluctuating levels of nutrients are factors that significantly influence greenhouse gas emissions from soda lakes in the Pantanal, considered less common than emissions from freshwater lakes. The Pantanal is the world's largest tropical wetland, with an area of 153,000 km2, mostly (77.41%) in southwestern Brazil, but also partly in Bolivia (16.41%) and…

It radically shifted the way the world looked at the environment, but created a wave of misinformation we're still dealing with today.

Perseverance science team member Amy Williams discusses the rover's recent discovery of a rock with features and chemistry that could have been produced by...

"Forever chemicals" is a hot news item. The public is paying attention to them because they stick around for very long periods of time – including in your body – where they bioaccumulate. This has caused concern that they may cause cancer, although this has not been proven. Why does this group of chemicals stay around for so long? Chemistry explains.

NASA has announced the first detection of possible biosignatures in a rock on the surface of Mars. The rock contains the first martian organic matter to be detected by the Perseverance rover, as well as curious discolored spots that could indicate the past activity of microorganisms.

The Perseverance rover has found evidence in a leopard-spotted rock that could suggest microbial life once existed on Mars billions of years ago, NASA said.

The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is
