This illustration provided by Mark P. Witton in March 2023 depicts a juvenile Edmontosaurus being eaten by a Tyrannosaurus rex with a lipped mouth. The teeth on T. rex and other big theropods were likely covered by scaly lips, concludes a study published Thursday, March 30, 2023, in the journal Science. The dinosaur's teeth didn't stick out when its mouth was closed, and even in a wide open bite, you might just see the tips, the scientists found. (Mark P.

Has T. rex lost its bite? Menacing snarl may be wrong

The Tyrannosaurus rex is often shown baring massive, sharp teeth, like the ferocious creature in “Jurassic Park.” But new research suggests that this classic image might be wrong. Read story

Study says warming-fueled supercells to hit South more often

March 28, 2023, 8:32am Nation & World

America will probably get more killer tornado- and hail-spawning supercells as the world warms, according to a new study that also warns the lethal storms will edge eastward to strike more frequently in the more populous Southern states, like Alabama, Mississippi and Tennessee. Read story

In this photo provided by researcher Rui F. Oliveira, a zebrafish, bottom, is monitored to see its reaction to a video of another at a laboratory in Oeiras, Portugal in March 2023. A study published on Thursday, March 23, 2023, in the journal Science shows that a relaxed fish can detect fear in other fish, and then become afraid itself - and that this ability is regulated by oxytocin, the same brain chemical that underlies the capacity for empathy in humans.

The original locks of Ludwig van Beethoven are presented at the Beethoven Haus in Bonn, Germany, that were used to sequence the genome of the world famous composer by an international team of researchers led by Cambridge University, Tuesday, March 21, 2023. Scientists have pulled Beethoven's genome from locks of his hair to look for clues about his many health problems.

This image provided by NASA/JPL-Caltech shows an artist's conception of what the surface of the exoplanet TRAPPIST-1f may look like, based on available data about its diameter, mass and distances from the host star. The Webb Space Telescope has found no evidence of an atmosphere at one of the seven rocky, Earth-size worlds orbiting a nearby star. Scientists say that doesn't bode well for the rest of the planets in this solar system, some of which are in the sweet spot for harboring water and, therefore, life. In a study published Monday, March 27, 2023 a NASA-led team reported little if no atmosphere exists at the innermost planet in the Trappist system, 40 light-years away.
