A newly discovered, carnivorous lizard ostensibly represents what most casual onlookers would perhaps perceive to be a dinosaur; however, it is in fact a precursor of the modern crocodile.

When bumble bees fight invasive Argentine ants for food, bees may win an individual skirmish but end up with less to feed the hive.

A new study shows, for the first time, that cow cells can naturally become immortal—continuing to divide indefinitely without genetic modification or any abnormal transformation. This overturns long-held assumptions that bovine cells could only be immortalized through gene editing, providing a safe, stable, and scalable source of cells for cultivated beef production. The finding removes one of the biggest technical and regulatory barriers to producing affordable cultivated beef, a potential game-changer for creating sustainable, ethical meat without the environmental toll of traditional livestock farming.

University of Iowa biologists discovered that a New Zealand freshwater snail duplicated its entire genome, capturing a rare evolutionary transitory state. The finding shows how large-scale genetic events can generate the raw material needed to fuel significant new adaptations and innovations in animals. Results appear in the journal Genome Biology and Evolution.
