Doctors often need to compare two MRI images to track changes in the body over time, but the process of lining up the images to make accurate measurements is extremely time-consuming. It can take hours for a computer to match all the locations in a 3D map, but researchers from …

Archaeologists from the Cornwall Archaeological Unit and English Heritage have found a stone inscribed with Christian symbols as well as Latin and Greek letters at Tintagel Castle in Cornwall, England, a site linked with the legend of King Arthur. The ruins of the upper mainland courtyards of Tintagel Castle, England. …

An international team of researchers has discovered five new species of snail-eaters (tribe Dipsadini) living in the forests of Ecuador and Peru. The five newfound species of snail-eating snakes, from top left to bottom right: the Bev Ridgely’s snail-eater (Sibon bevridgelyi), male; the Bob Ridgely’s snail-eater (Dipsas bobridgelyi), male; the …

Astronomers detected a massive outpouring of energy from a distant galaxy 10 years ago, which would usually mean a supernova event — the death of a star. The galaxy in question is actually two galaxies colliding, so the region known as Arp 299 is rich with supernovae. However, the signal …

The vast majority of life on our planet uses red light (680 to 700 nm) in the process of photosynthesis, but the new type uses near-infrared light (750 nm) instead: it was detected in a wide range of cyanobacteria, one of the largest groups of bacteria on Earth, where they …

In a paper published this week in the journal Scientific Reports, paleontologists have described an extinct genus and species of frog, Electrorana limoae, preserved in mid-Cretaceous (99 million years old) amber from Myanmar. About 99 million years ago, a tiny juvenile frog in what is today Myanmar was suddenly trapped …

Around 1.4 billion years ago, a day on Earth lasted approximately 18.7 hours, according to a study published in the Proceedings of the National Academy of Sciences. And this is at least in part because the Moon was closer and changed the way our planet spun around its axis. Professors …

Things on Mars may have gone from bad to worse for the Opportunity rover. The dust storm on the planet shows no signs of abating, and NASA now says the rover has missed its latest check-in. That suggests its batteries are drained, and that could spell the end for this …

Many of us have had chance encounters with medical professionals who aren’t yet adept at drawing blood. After just one of these unpleasant experiences, you’ll understand the appeal of the new venipuncture robot from Rutgers University. Not only can this robot find a vein on the first try, but it …
