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.

Primary central nervous system lymphoma (PCNSL) is a rare and highly aggressive lymphoma or tumor of the brain. While ventricular brain lymphoma is even rarer, its clinical characteristics and treatment strategies remain less explored. Now, researchers have evaluated the clinical features of PCNSL lesions involving the ventricles. They found that this rare tumor type shares key features with other brain lymphomas, suggesting a unified treatment approach.
