Microbial mats growing in hot spring-fed streams, like these here in Yellowstone National Park, offer insights into the evolution of life on early Earth. As mineral-laden water flow over the mat, silica crystals grow, and the mat eventually turns into stone. The lithified mat is an analogue of conical stromatolites that are found in sedimentary rocks that are billions of years old.

A look back in time

By linking the odd geometry of bacterial growths to photosynthesis, researchers may have a new way to study Earth’s oldest fossils.

Based on topographic data obtained by NASA’s Magellan spacecraft, this figure shows the volcanic peak Idunn Mons in the Imdr Regio area of Venus. The colored overlay shows the heat patterns derived from surface brightness data collected by VIRTIS aboard the European Space Agency’s Venus Express spacecraft. The brightness signals the composition of the minerals that have been changed due to lav...

Figuring out where to put the carbon

If we plan to keep using fossil fuels, we need to figure out how to sequester the resulting carbon dioxide. New tools from MIT could help evaluate where to do it — and how to keep it contained.
