Sellam found long, twisting, microscopic filaments of a type previously identified as being microbial fossils belonging to sulfur-oxidizing bacteria. These fossil remnants were surrounded by clay ...

"Because they are fossils, we cannot be 100% sure about the species." They might have been a kind of algae or bacteria. After that internship and earning three Master's degrees, Sellam got a couple ...

If Mars ever hosted microorganisms in its bygone oceans, their fossils might still be preserved in minerals—and now, we have ...

“In the few fossil samples that are of surviving (cycad) lineages, and that are not so old -- 20, 30 million years -- we see the same nitrogen signature as we see today,” Kipp said. That means their ...

This breakthrough can significantly reduce the cost of green hydrogen production, making it a more viable alternative to fossil fuels. The use of bio-engineered bacteria offers a sustainable and ...

Until now, the least “green” thing on the planet has been fossil fuels. But that could change. A University of Minnesota team is putting bacteria to work turning carbon dioxide – the primary ...

This means that if microbes such as bacteria lived there, traces of their presence could be preserved as fossils. "Gypsum has been widely detected on the Martian surface and is known for its ...
