A remarkable new discovery is shedding light on one of the greatest survival stories in Earth's history, and answering a decades-old scientific mystery. Lystrosaurus, a hardy, plant-eating mammal ancestor, rose to prominence in the wake of the End-Permian Mass Extinction some
Like most bacteria, Vibrio cholerae lives under constant attack from viruses. To survive, bacteria equip themselves with antiviral immune systems. Previous work has shown that V. cholerae carries a large genetic element called a sedentary chromosomal integron (SCI). This
Hedgehogs, elephants, pangolins, bears or fennec foxes: many wild species are sold as pets, hunting trophies, for traditional medicine, biomedical research, or for their meat or fur. These practices, whether legal or illegal, concern one-quarter of all mammal species. Now a
New York State and New England have optimal conditions for grass-fed beef production—with an abundance of pasturelands and forage—but higher production costs have made farmers wary of expanding operations. In a new analysis, published in Agricultural Systems, researchers find
Some animals can regrow lost body parts. Salamanders and frog tadpoles can rebuild entire limbs after amputation. Mammals cannot. For decades, biologists have tried to understand why. Now a team led by Can Aztekin at EPFL (now at the Friedrich Miescher Laboratory of the Max
