RNA bundled in lipid nanoparticles trains T cells in mice to eliminate cancer. Coupled with noninvasive imaging, researchers tracked the in situ CAR-T cells to assess their effectiveness and safety.

Human organs-on-chips and organoids offer new alternatives to animals for drug development, but there is still a long way to ...

While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other ...

Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different ...

Researchers identify specific genes involved in sensory hair cell regrowth in zebrafish, potentially informing hearing loss ...

Some mammals are capable of hibernating during periods of low food availability in an effort to conserve energy and survive.

When we think of blood, the colour red usually comes to mind. That’s because in most animals, blood gets its red colour from hemoglobin, an iron-rich protein that carries oxygen. But not all ...

Lake Natron is a soda lake in northern Tanzania with a volcanic geology that maintains the water's pH around 10.5, which is almost as caustic as ammonia. Some life-forms thrive there nevertheless.

So what do non-human animals feel? Perhaps unsurprisingly, most of the research concerning emotion in non-human animals has been on our closest relatives, such as chimps and bonobos, as well as ...

The distinctive blue color of certain animals’ blood stems from fundamental differences in oxygen-carrying proteins. While humans and other vertebrates use hemoglobin, which contains iron that gives ...
