These so-called optical lattices act as versatile potential landscapes to trap ultracold quantum gases of bosons and fermions. They form powerful model systems of quantum many-body systems in ...

All living mammals produce greenhouse gases like methane, carbon dioxide and nitrous oxide, experts say. Cattle and other livestock contribute to agricultural greenhouse gas emissions.

Though the vast majority of planet-warming gases come from people burning fossil fuels, a separate study released Tuesday suggests that last year’s sudden spike was likely driven by a different ...

The method hinges on worlds that look nothing like Earth, and gases rarely considered in the search for extraterrestrials. Scientists have identified a promising new way to detect life on faraway ...
