A newly discovered species of tardigrade that glows blue when exposed to ultraviolet light uses the powers of fluorescence as a protective shield, according to new research.
Surprising quantities of bacteria have been found living in clay-rich rocks under the Pacific seafloor. The discovery raises the possibility of equally resilient microbes living deep beneath the surface of Mars.
Meteorites are an unappreciated food source for a specific metal-loving microorganism, according to new research. The finding could reveal an entirely new chemistry that facilitated the emergence of life on Earth—or possibly even how life got here in the first place.
