Artemis missions could put the most powerful imaging telescope on the moon
Ground-based interferometry on Earth has proven to be a successful method for conducting science by combining light from several telescopes into acting like a single large telescope. But how can an ultraviolet (UV)/optical interferometer telescope on.....»»
Study shows microbial diversity differences in volcanic cones and craters
Volcanic activity alters the Earth's surface and promotes the development of new ecosystems, providing valuable models for studying soil formation processes such as microbial composition and vegetation succession. Increasing evidence suggests that so.....»»
Researchers identify novel approach to minimize nitrogen loss in crops
While agriculture producers apply nitrogen fertilizer to supply nutrients to their crops, they can't always keep those nutrients in the soil for maximum efficiency, often losing them into the atmosphere or water supply as nitrates and nitrous oxide......»»
