Paleontologists have announced the discovery of a new genus and species of baracromian ichthyosaur, based on the fossilized skull found in the Água de Madeiros Formation, Portugal.

The newly-discovered species belong to the rare bee subgenus Austrochile (genus Megachile). They construct brood cells from resin that are stuck individually to twigs or in clusters on the bark of trees. The authors therefore propose ‘resin pot bees’ as common name for the bees in this subgenus.

Mars hosts various auroral processes despite the planet’s tenuous atmosphere and lack of a global magnetic field. To date, all aurora observations have been at ultraviolet wavelengths from orbit. In a new paper, planetary scientists describe the discovery of green visible-wavelength aurora, originating from the atomic oxygen line at 557.7 nanometers (nm), detected with the SuperCam and Mastcam-Z instruments on NASA’s Perseverance rover.

Topographical wrinkle patterns caused by prolonged human hand immersion in water are repeatable and consistent at different timepoints, according to new research by Binghamton University scientists.

Trilobites were a diverse group of ancient marine arthropods. Many trilobites lived on the seafloor but some occupied open water. New research has resolved the evolutionary history of a bizarre group of trilobites called the cyclopygids, named after the mythical one-eyed monster Cyclops, as their eyes gradually merged into a single large visual surface as they evolved.
