Researchers completed a genetic map of living and extinct rhino species, finding that genetic diversity has always been low in rhinos. The finding could help guide conservation efforts.
Scientists created brain organoids from stem cells of patients with Rett syndrome and were able to observe signs of the disease in the organoids. The development suggests how organoids can be used to study brain functions.
Scientists found a new species of lepidosaur — a subclass that includes snakes and lizards — in Argentina. It was identified from one of the oldest lepidosaur fossils ever discovered, from a period with few surviving fossils.
A study of T. rex mandibles revealed a complex network of nerves in the dinosaur’s mandibles, similar to what’s found in crocodiles. That means T. rex mandibles were more sensitive to touch and movement than previously thought.
Photos of Hurricane Henri heading toward the U.S. East Coast were captured by the International Space Station. Afterward, the storm was downgraded to a tropical depression but still caused severe flooding.
Scientists found an extremely rare brain tissue fossil from an ancient arthropod. The fossil proves the existence of a frontal brain region that scientists previously hypothesized based on modern arthropods.
Using NASA data, scientists determined that dust in Martian snow could make it easier to melt. The finding could aid studies of possible liquid water on Mars and help illustrate the planet’s climate history.
