The human immunodeficiency virus (HIV), which is the cause of AIDS, is a master of deception, using just nine genes to hijack ...

When probes are inserted into the brain for research or clinical purposes, the electrical activity of neurons is recorded.

By examining genetic clues that linger in adult cells, scientists have now gained surprising insights into the developmental ...

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 ...

When you were first conceived, you were a single cell. From this basic fact, we can extrapolate a few things, most especially that all the cells that make up your body today came (indirectly) from ...

An estimated 86 billion neurons in the average human brain govern our body’s functions and conjure — somehow — the human mind. C. elegans has 302 neurons in one sex and a few more in the other.

When a rhinovirus, the most frequent cause of the common cold, infects the lining of our nasal passages, our cells work together to fight the virus by triggering an arsenal of antiviral defenses. In a ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...

Scientists have trained a computer made from living human neurons to play the classic video game Doom, marking a strange but important step forward in biological computing. A clump of roughly 200,000 ...
