How the octopus uses its 'taste by touch' sensory system to feel out potential mates

The Environmental Protection Agency proposed Thursday to include microplastics and pharmaceuticals on a list of contaminants in drinking water for the first time, a step that could lead to new limits on those substances for water utilities.

Scientists have discovered that a highly unusual giant planet—sometimes called "forbidden"—could have an atmosphere with fewer heavier elements than its host star. University of Birmingham astrophysicist Dr. Anjali Piette worked with an international research team to analyze James Webb Space Telescope data from the exoplanet TOI-5205 b. This is a Jupiter-sized planet orbiting a star about four times the size of Jupiter and about 40% the mass of the sun.

Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense gravitational pull, the rotational spins of galaxies would force them to simply fly apart. But now, scientists have found a string of galaxies that seem to be missing their dark matter entirely. The latest in this string, known as NGC 1052-DF9, is described in a new paper available on the arXiv preprint server, by Michael Keim, Pieter van Dokkum and their team from Yale. I
