Neural tissue normally dies quickly without oxygen. Yet bird retinas—among the most energy-demanding tissues in the animal ...

How different cells organize themselves, within a tissue, to support tissue functions remains poorly understood. Now, researchers have developed an AI-powered algorithm to help understand how cells ...

Two complementary research articles reveal that central and peripheral circadian clocks coordinate to regulate the daily activity of skin and muscles. The coordination between the two clocks (central ...

Discovered in the 1970s, circadian clocks are essential for the regulation of biological time in most cells in the human body. These internal mechanisms adjust biological processes to a 24-hour cycle, ...

Tissue engineering is an interdisciplinary field that combines principles from engineering, biology, and materials science to develop biological substitutes that restore, maintain, or improve tissue ...

In good news for future animation figureheads, there might be a new way to revive frozen brains without damaging them. Scientists in China have developed a new chemical concoction that lets brain ...

Disrupted function of 'cleaning cells' in the body may help to explain why some people with obesity develop type 2 diabetes, while others do not. A study describes this newly discovered mechanism.

Tweaking a pattern of wound healing established millions of years ago may enable scar-free injury repair after surgery or ...

The discovery fundamentally changes the understanding of a structure in the avian eye that has been misinterpreted for centuries.

Combining lab-grown muscle tissue with a series of flexible mechanical joints has led to the development of an artificial hand that can grip and make gestures. The breakthrough shows the way forward ...
