In experiments with mice, Johns Hopkins Medicine scientists report new evidence that precursors of myelin-producing cells—one ...

Researchers have created an early map of some of the human body’s estimated 37.2 trillion cells. Each type of cell has a unique role, and knowing what all the cells do can help scientists better ...

Some parts of our bodies bounce back from injury in fairly short order. The outer protective layer of the eye—called the cornea—can heal from minor scratches within a single day. The brain is not one ...

Researchers find obelisks, mysterious RNA molecules in human bacteria that challenge our understanding of viruses and ...

Many of the body's processes slow down or falter as we get older, including tissue regeneration. In a new study, researchers ...

There are hundreds of cell types in the human body, each with a specific role spelled out in their DNA. In theory, all it ...

When tissue is severely damaged, surviving cells can respond in a concentrated burst of biological repair known as ...

Scientists have transformed enigmatic cell structures, called vaults, into storage units for messenger-RNA molecules made in ...

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 ...

New evidence shows that precursors of myelin-producing cells — one of the few #brain cell types that continue to be produced ...
