2+ hour, 12+ min ago   (651+ words) Long-lived bats appear to combine powerful immune defenses with unusual strategies for eliminating damaged cells, potentially helping them avoid cancer and disease for decades. Researchers hope these genetic tricks could eventually reveal new ways to protect human health during aging....

2+ day, 20+ hour ago   (874+ words) Scientists at Monash University have proposed a new global strategy to address a major weakness in biodiversity conservation. Insects are essential to ecosystems, agriculture, and food production, yet conservation efforts across tropical regions often fail to account for them. The…...

3+ day, 12+ hour ago   (485+ words) Researchers discovered that combinations of toxin-blocking proteins naturally found in rattlesnake blood can powerfully neutralize venom from several dangerous snake species. In lab tests, the mixtures were about 10 times more potent than a current commercial antivenom, pointing toward a new…...

3+ day, 14+ hour ago   (109+ words) The extinct “American cheetah” was not really a cheetah at all, but a puma relative with an unexpectedly flexible lifestyle. Fossils from the Yukon suggest northern populations survived partly by eating fish, possibly including salmon, while southern cats hunted on…...

4+ day, 27+ min ago   (421+ words) A critically endangered roloway monkey has given birth just months after surgeons performed an unusual operation that saved her foot from amputation. Her new daughter, Lagertha, is an important addition to a species believed to number fewer than 2,000 in the…...

6+ day, 4+ hour ago   (164+ words) A common frog found across Ecuador and Colombia has finally been recognized as its own species after more than a century of mistaken identity. Museum specimens from the 1800s helped scientists reveal that Pristimantis milpe had been hiding in plain sight…...

1+ week, 1+ day ago   (1115+ words) At first glance, stromatolites and their close relatives, microbial mats, can look like little more than dark, ancient rocks. In reality, they are densely packed, layered communities built by microbes. Billions of years ago, before animals and plants existed, stromatolites…...

1+ week, 1+ day ago   (149+ words) Scientists discovered that more than 500 species of vesper bats possess two separate sets of antibody genes, an immune arrangement never before found in mammals. The surprising system could help explain how bats tolerate so many viruses without becoming seriously ill....

1+ week, 2+ day ago   (490+ words) A meter-long scorpion with massive pincers stalked ancient Britain 415 million years ago, long before forests and the better-known age of giant insects. Its surprising size and possible semi-aquatic lifestyle could reshape ideas about how early arthropods became giants....

1+ week, 3+ day ago   (601+ words) Snake embryos begin life curled into a distinctive right-handed spiral, and scientists may finally know why. Their bodies grow faster than their guts, creating a tether that forces the lengthening embryo to buckle and twist inside the egg. Researchers reached…...
