Meet Crocodylus lucivenator, a 12- to 15-foot predator that hunted iconic Lucy's species
More than 3 million years ago, when our ancient ancestors embodied by the iconic Lucy were roaming the African landscape, they would have feared a big, bad crocodile with a prominent lump on its head, patiently lurking in rivers and lakes to attack them. According to a research

Your cat is likely to live longer if you don't let them roam—new study
We all know cats represent a major threat to native animals and birds. Australia's 5.3 million domestic cats kill a total of 546 million animals each year in Australia. What's less well known is allowing your domestic cat to roam outside exposes them to considerable danger—and
What's it like to be a bat? Scientists develop new solution to the puzzle of animal minds
In 1974, philosopher Thomas Nagel posed a deceptively simple question: "What is it like to be a bat?" His point wasn't really about bats. He was offering a provocative challenge about the limits of understanding another mind: no matter how much we try, we cannot access what it
The Rubin Observatory's LSST will detect imminent impactors before they crash into Earth
The Vera Rubin Observatory (VRO) has barely begun observations and is already wowing us. Images like its Cosmic Treasure Chest have us anticipating even more cosmic glory. And when the observatory sent out 800,000 alerts in one night in February, we got a taste of the
