Argentine 'gargoyle' shows how huge predatory dinosaurs evolved

Fossils found in Argentina of a ferocious dinosaur with a huge head covered in bumps and crests reminiscent of a gargoyle are providing insight into the evolution of some of Earth's biggest predatory dinosaurs including a curious trend toward puny arms. Scientists said on Thursday they discovered in northern Patagonia extensive skeletal remains of a previously unknown species called Meraxes gigas, including one of the most complete skulls of a large meat-eating dinosaur ever unearthed. Meraxes, which lived about 90 million years ago during the Cretaceous Period, was roughly 36-39 feet (11-12 meters) long and weighed about 9,000 pounds (4 metric tons).

Wastewater study technique finds virus variants sooner; many patients are using meds affected by Paxlovid

The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review. A new wastewater study technique find variants earlier

Uterus transplants allow successful pregnancies in U.S. women-study

More than half of U.S. women who received a uterus through a transplant went on to have successful pregnancies, a new study shows. Between 2016 and 2021, 33 women received uterus transplants in the United States and so far 19 of them, or 58%, have delivered a total of 21 babies, researchers reported on Wednesday in JAMA Surgery.
