(Phys.org)—Researchers working on the Search for Extraterrestrial Intelligence (SETI) project have completed their first "directed" search of a part of space and report in a paper they've uploaded to the preprint server ...
Photosynthesis maintains Earth's habitability for life as we know it, and shapes the way we search for habitable worlds around distant stars. Scientists have discovered a microbe that can use low-energy light to perform photosynthesis. ...
