People thought that leprosy, also known as Hansen’s disease, came to the Americas with European colonizers hundreds of years ago. But a new study that is changing the way we think about this has come out. Researchers looking at 4,000-year-old skeletons from Chile have found genetic proof of Mycobacterium lepromatosis, a rare and severe form ...
Mario Rana, an amateur astronomer and NASA contributor, pointed his telescope at Saturn on the morning of July 5, 2025. He may have seen history being made. Astronomers around the world are trying to figure out if this was the first time anyone has ever seen an impact on Saturn. There was a brief but ...
New research confirms that the huge amounts of water stored behind dams have not only changed sea levels but also the planet’s axis of rotation. This shocking discovery shows how much humans have affected the Earth’s geophysical processes. A study in Geophysical Research Letters says that building dams over the past 200 years has caused ...
A treasure trove of 380-million-year-old fossils in the sun-baked rocks of Western Australia’s Gogo Formation is changing the story of how the first land animals hunted and ate. A new study published in iScience gives us shocking new information about the diets of ancient lungfish, which are the ancestors of fish and four-legged vertebrates like ...
Geologists have been studying rocks, fossils, and ice cores for hundreds of years to learn about Earth’s past climate. A new study has reconstructed 540 million years of sea level changes with an accuracy that has never been seen before. This study shows patterns that could change how we think about climate change. This research, ...
In a cosmic battle 3.8 billion light-years away, two galaxy clusters crashed into each other with such force that they tore apart the fabric of spacetime. This left behind a lot of clues about dark matter. NASA’s James Webb Space Telescope (JWST) has now given us the clearest picture yet of the Bullet Cluster, a ...
Newly analyzed jawbones from 380-million-year-old lungfish are shedding light on the feeding behaviors of our earliest vertebrate ancestors. Discovered in the Gogo Formation of northern Western Australia, these fossils reveal a surprising diversity in skull and jaw structure, offering clues about how early lobe-finned fish adapted to different diets and ecological roles before vertebrates made ...
NASA’s astronaut, Nichole “Vapor” Ayers, has photographed a spectacular atmospheric event – a large red ‘jellyfish’ sprite soaring above a thunderstorm in North America. The striking image, taken from the International Space Station (ISS) on July 3, 2025, gives scientists a rare view of sprites from the top which is a form of lightning and ...
Researchers have found a way to turn an unlikely waste product, human urine, into a high-value material for medical implants, construction, and even archaeology. This sounds like something out of science fiction. A team at the University of California, Irvine, is in charge of this new idea, which is funded by the U.S. military’s Defense ...
A newly identified wrist bone in two non-avian dinosaurs has challenged long-held assumptions about the evolution of flight. Researchers have discovered that theropods, bird-like meat-eating dinosaurs, possessed a carpal bone called the pisiform, once thought to be unique to birds. This finding suggests that the anatomical foundations for flight were already in place millions of ...
