Hybrid work is not always the golden compromise employees expect—even as more companies implement it

The strength of gravity is different on every body in the solar system. Whether it's the crushing weight of Jupiter or the minuscule pull of a small asteroid, this fundamental force of physics still has a major impact on the material those bodies are made up of. A new paper from researchers at the University of Duisburg-Essen and the German Aerospace Center (DLR) showcases just how different it can be by letting planetary simulants freefall inside a giant drop tower and measuring how "fluffy" th

A species of moth that was first described in 1818 was believed to be a single species. However, it has since been discovered that it is actually a complex of species, eight of which are found in Brazil. These findings are the result of a study that integrated molecular techniques, morphological data, and the identification of host plants from populations in the Amazon, Atlantic Forest, and Pantanal regions.

Depression, anxiety and sleep disorders are among the conditions often treated with antidepressant drugs. Yet, up to 90% of these drugs pass through the body into wastewater. They're also difficult to remove during water treatment, presenting a possible risk of environmental contamination and threats to ecological and human health. Now, researchers reporting in Environmental Science & Technology have found some antidepressant drugs at levels that could be harmful to aquatic wildlife in North Car

A research team led by Professor Shuichi Hiraoka at the University of Tokyo and Professor Masanori Tachikawa at Yokohama City University has quantitatively analyzed how molecules pass through dynamic nanoscale pores using self-assembled molecular "nanocubes" in water. The researchers discovered an unexpected phenomenon: For linear alkane molecules, longer molecules passed through the molecular gates faster than shorter ones.
