Scientists have developed a new class of microscopic antibody fragments capable of functioning inside human cells, overcoming a long-standing limitation in biomedical science.

The human body may seem like a single, self-contained system, but it actually hosts trillions of microscopic organisms. These ...

A new, more life-like physical model of microscopic nerve fibers called axons could speed up the discovery of medicines for ...

A toxic protein forms dynamic pores in the membranes of brain cells—and that may be the key to understanding how Parkinson's disease develops. This is the conclusion of a new study from Aarhus ...

Researchers are learning how to refill the energy reserves of aging human cells, turning a long-standing metaphor about “cellular batteries” into a literal engineering challenge. By training healthy ...
