Thick clay layers on Mars may have been stable place for ancient life

University of Texas at Austin
Peer-Reviewed Publication

The planet Mars is home to thick layers of clay that can span hundreds of feet. Since they need water to form, these outcrops have long been of interest to scientists looking for signs of past life on the Red Planet.

In a new study in Nature Astronomy, scientists from The University of Texas at Austin and collaborators took a closer at these clay terrains and found that most formed near standing bodies of surface water, which were common on Mars billions of years ago. This environment would help foster the chemical weathering needed to create thick, mineral-rich layers of clay and could have provided the right mix of water, minerals and a calm environment for life to develop.

Amazon trees under pressure: New study reveals how forest giants handle light and heat

Michigan State University
Peer-Reviewed Publication

In a recent study published in New Phytologist, researchers at Michigan State University have uncovered how Amazon rainforest canopy trees manage the intense sunlight they absorb — revealing resilience to hot and dry conditions in the forest canopy while also offering a way to greatly improve the monitoring of canopy health under increasing extreme conditions. The study was made possible by funding from the National Science Foundation and NASA.
