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 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 ...

A human female is born with all the egg cells she will ever have. The possibility for the development of new oocytes is zero. Given this constraint, it is crucial that these gametes remain healthy and ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

For centuries, curious observers have been grappling with the question “What is life?” Early naturalists documented observations about the living world long before anyone knew about cells. Their ...
