Microbe Goo Could Help Guide the Search for Life on Mars
Sticky substances secreted by microbes may help create landforms on Earth. And new research shows that these substances are more preserved in iron-rich sediment. Mars is decidedly iron-rich (it’s the Red Planet, after all), so the new study adds to evidence that microbe goo could help researchers explain landform creation there. “I think this is […]
