Researchers have long known that releasing domesticated ducks can alter wild populations. Now, a study led by a doctoral student at The University of Texas at El Paso has documented, for the first time in North America, when and where these genetic changes took place and tied them directly to more than a century of releases.

Researchers highlight ferroptosis's dual roles in plant immunity

When plants encounter pathogens, they can defend themselves by rapidly killing infected cells to restrict pathogen spread. This immune response, known as the hypersensitive response (HR), was first described in 1915. However, the molecular mechanism underlying HR cell death remai

Fractal patterns reveal hidden limits to AI predictability

Researchers at the University of Sydney have identified a fundamental mathematical reason why artificial intelligence systems can learn different behaviors even when trained under almost identical conditions, a discovery that could help improve the reliability and trustworthiness
