Scientists have pinpointed and described unusual subtypes of fat cells that may help scientists explain why gut fat is linked to poor health. The research could open up new avenues for medical treatments.

A mechanism that activates specific muscles in our ears is a leftover from our evolutionary past, back when our ancestors depended more on their hearing for survival.

There's an idea that larger muscles burn a lot more energy while at rest. But is that true?

A new study describes a type of cartilage that may have been discovered, forgotten and found again at several points in history.

Researchers think that microgravity could help grow liver "organoids" that could be used in medical research and even in transplant surgeries, someday.

"Zebrahub" is an atlas of cells in developing zebrafish embryos, and scientists say it will help us learn about our own biology, too.

A common food dye can turn the skin of living mice transparent, but we don't yet know if it'll work in humans.

Scar tissue differs from normal skin in a few important ways.

Organoids can replicate each component of the human heart, from its chambers to its veins.

The newly-discovered cells help shed light on how the liver repairs itself after damage.
