Soil Microbes Alter DNA in Response to Warming

Atlanta, GA

Scientists studying grasslands in Oklahoma have discovered that an increase of 2 degrees Celsius in the air temperature above the soil creates significant changes to the microbial ecosystem underground.

In Barrow, snow-covered ice pack extends in every directly except inland. The ultimate source of the molecular chlorine is the sodium chloride in sea salt, Huey said, most likely from the snow-covered ice pack. How the sea salt is transformed into molecular chlorine is unknown. Credit: Greg Huey.

Evidence found for granite on Mars

Atlanta, GA

Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth -- could have formed there, according to a new study. The findings suggest a much more geologically complex Mars than pre
