They had huge teeth — about 12 inches long from the base to the tip, which they used to eat almost anything they could get their teeth on during the Early Cretaceous.“In terms of size, they are some of the biggest,” says Leslie Noe, a paleontologist at the University of the Andes in Bogota, Colombia.And the fearsome jaw is all we know about the Kronosaurus queenslandicus — the o ...read more

And, it’s a trait that many of us try to unlearn or suppress through medication, cognitive behavioral therapy, mindfu ...read more
Mars holds enough water to cover the entire planet with an ocean about a mile deep, according to a new study in Proceedings of the National Academy of Sciences. But accessing that water would require drilling wells 6 miles down. On Earth, creating wells that reach even a half mile down is a challenge. Water was first discovered on Mars in 2020, it was frozen in polar ice caps. But scientists had also noticed signs that much more once flowed on the surface through channels resembling riverbeds. F ...read more
The Titanic, discovered in 1985 deep beneath the ocean off of Newfoundland, is the most iconic shipwreck in the world. The massive luxury liner sank in 1912 after hitting an iceberg, but it was well preserved in its freezing resting place on the ocean floor.In 2021, the Oceangate, a state-of-the-art submersible, made it possible to visit the site, but just two years later, everyone aboard the vessel was tragically killed when it imploded deep in the blue, and all the crew members were lost to th ...read more
Parasites take an enormous toll on human and veterinary health. But researchers may have found a way for patients with brain disorders and a common brain parasite to become frenemies.A new study published in Nature Microbiology has pioneered the use of a single-celled parasite, Toxoplasma gondii, to inject therapeutic proteins into brain cells. The brain is very picky about what it lets in, including many drugs, which limits treatment options for neurological conditions.As a professor of microbi ...read more
