A newly identified crocodile species nicknamed “Lucy’s hunter” prowled Ethiopia’s rivers when Lucy’s species walked the Earth more than 3 million years ago。 The giant predator was likely the most dangerous animal in the ecosystem and may have regularly hunted early human relatives
Plague was already a deadly killer 5,500 years ago, long before cities, farming, or the rat-infested conditions usually linked to historic outbreaks。 By analyzing ancient DNA from hunter-gatherer cemeteries in Siberia, researchers discovered early plague strains in nearly 40% of the individuals studied and found evidence of rapid family-based outbr
Millipedes may have been crawling across Earth's landscapes nearly 460 million years ago, long before vertebrates ventured onto land。 A new study finally completes their evolutionary family tree, revealing surprising clues about these ancient ecosystem engineers and their early chemical defenses
A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older。 Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health
A spectacular fossil fish discovered on a remote cliff in New Zealand nearly 30 years ago has finally revealed its full story thanks to an unexpected discovery: the original collector’s long-lost field notebooks。2-meter fossil, preserved in stunning three-dimensional detail, belonged to an ancient tarpon-like predator that cruised New Zealand water
A newly discovered feathered dinosaur called Jian changmaensis may be the missing predator responsible for mysterious piles of crushed prehistoric bird bones in China。 The four-winged glider, a close cousin of Velociraptor, helps reveal how early birds and their dinosaur relatives shared the same ancient landscape
A new biomaterial made from jackfruit latex, pomegranate peel, and simvastatin could transform the treatment of severe gum disease。 Early tests suggest it not only combats infection and inflammation but may also help rebuild lost bone and tissue around teeth
A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision。 The discovery suggests some early planets formed from dramatically different materials than Earth and Mars, rewriting part of the solar system’s origin story
Researchers gave top AI models a classic attention test used in psychology and found a major flaw。 While the models could correctly name colors in short lists, their performance deteriorated sharply as the task became longer and more complex。 Some leading systems fell from over 90% accuracy to nearly complete failure
