A new physics breakthrough shows how Einstein’s theory of general relativity continues to hold up, even for “balding” black holes. Black holes are regions of spacetime where gravity’s pull is so strong that nothing, not even light, can escape from being dragged in and “eaten.” Einstein’s theory of general relativityContinue Reading
Experiments coaxed the geckos to regrow tails with some nerve tissue and bonelike cartilage Regenerating body parts is never easy. For instance, some lizards can grow back their tails, but these new appendages are pale imitations of the original. Now, genetically modified stem cells are helping geckos grow back betterContinue Reading
An odd fast radio burst has been seen exploding over and over. Astronomers have watched a mysterious cosmic object shoot out 1,652 blasts of energy over a short period of time. Though researchers are still stumped as to what caused the repeated eruptions, they hope the observations will help themContinue Reading
On Jupiter, a storm’s been brewing for more than 300 years. Known as the Great Red Spot, this swirling high-pressure region is clearly visible from space, spanning a region in Jupiter’s atmosphere more than 10,000 miles (16,000 kilometers) wide — about one and a quarter times the diameter of Earth.Continue Reading
What do you see in the photo? What do you see in this image of space gas and dust? Perhaps, the greenish blob puts you in mind of a frog, or a crocodile, or Slimer from “Ghostbusters.” One scientist is pretty sure he saw Godzilla. Much like clouds on Earth,Continue Reading
Indigenous people arrived on the islands centuries before Europeans The enigmatic, now-extinct Falkland Islands wolf had human visitors on the remote archipelago up to 1,070 years ago. The find suggests that Indigenous people could have originally brought the foxlike creatures, also known as the warrah, to the islands. Scientists haveContinue Reading
Gorongosa National Park’s elephants bear the physical consequences of poaching’s legacy When ivory poachers target elephants, the hunters can affect more than just animal numbers. In Mozambique, past hunting pressure led to an increase of naturally tuskless elephants in one park, a study finds. During the Mozambican Civil War, whichContinue Reading
12 newly described gecko species get scientific names inspired by their features Martial arts legend Jackie Chan may not be aware of this yet but some of his biggest fans are a group of adoring herpetologists from India. These scientists have named a newly identified gecko species, the Jackie’s dayContinue Reading
Modern sloths may be dedicated vegetarians, but at least one of their massive Ice Age cousins chowed down on meat when it had the chance. Darwin’s ground sloth — which could grow to over 3 meters long and weigh as much as about 2,000 kilograms — may have been anContinue Reading
David Julius and Ardem Patapoutian found nerve cell sensors for heat, cold, pain and pressure. Some touching research took the 2021 Nobel Prize in physiology or medicine. David Julius of the University of California, San Francisco and Ardem Patapoutian of the Scripps Research Institute in La Jolla, Calif., were awardedContinue Reading
