The human body replaces an estimated 330 billion cells each day while continuously rebuilding tissues and molecules. Most of ...

The human body feels solid and unchanging from one day to the next, but at the cellular level it is in constant motion.

A billion-year-old calcium signaling system in cyanobacteria reveals surprisingly ancient roots of cell-to-cell communication ...

Every cell in the human body carries the same 3 billion letters of DNA, yet a neuron, a heart muscle cell and a pancreatic beta cell each use that shared code to do entirely different jobs. How cells ...

Collagen, the protein that builds skin, bones, tendons and organs, exists inside cells as a liquidlike droplet rather than the long, rigid rod seen in textbooks over the last half-century, according ...

Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...

A study in the journal Nature sets a new record for the lifespan of lab-grown cells called organoids. These clusters of human cells in petri dishes are used as models of the human brain.

As the human brain takes shape before birth, a remarkable type of stem cell helps give it many of the features that make it ...

Mount Sinai researchers have published the first organ-wide human skin spatial atlas from across the body. It provides an unprecedentedly detailed view of healthy human skin, revealing cellular ...

Tiny human brain organoids survived for years outside the body, continued to mature, and even skipped ahead through stages of ...
