There’s a new T. rex in the fossil record, only this one terrorized the ancient seas. New research uncovers a new, massive species of mosasaur, a marine reptile that lived during the age of the dinosaurs. One of the largest mosasaurs known to date—stretching up to 43 feet long—this top predator was described from 80-million-year-old fossils that were found primarily in northern Texas decades ago. It was named Tylosaurus rex, or T. rex for short, meaning “king of the tylosaurs.”
The Sin Nombre virus – a hantavirus that can cause a deadly respiratory disease in humans – may be more widespread among rodent populations in parts of the Pacific Northwest than previously recognized. A recent study conducted in the Palouse region of Washington and Idaho found that nearly 30% of rodents showed evidence of past infection with the virus and about 10% were actively infected
Cities don’t just change the landscape, they change the weather. According to a new study analyzing tens of thousands of rain events in Texas, whether urban areas make rain worse, lighter or simply different depends strongly on the type of storm. The research, published in Nature, examines more than 40,000 warm‑season storms that passed over or near Dallas–Fort Worth, Austin, San Antonio and Houston between 1995 and 2017. By sorting storms into distinct categories and tracking their three‑dimensional structure using weather radar, scientists found that the four urban areas strengthen some storms while weakening others.
Researchers have uncovered a remarkable fossil site in a remote part of Canada’s Northwest Territories, offering unprecedented insight into the earliest evolution of complex animal life on Earth. Findings from the site represent life from the Ediacaran biota—soft-bodied organisms that lived on the seafloor more than 500 million years ago—and push back the origins of animal movement and sexual reproduction by 5-10 million years.
New research led by the University of Utah documents how carbon markets, a pillar of climate policy, fail to accurately account for the risks U.S. forests face from climate change. The team produced maps that show where the risk of loss from fire, insects and drought are most elevated, and therefore best avoided for forest preservation projects.
