Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different ...

In two new studies, scientists at Oregon Health & Science University have uncovered detailed blueprints of how certain molecular "gates" in human cells work—findings that could open doors to new ...

Every second, millions of blood cells are produced in the human body, and about 90% of the cells replaced daily are blood cells. These include red blood cells essential for oxygen transport, platelets ...

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 ...

One of the most well-studied cellular responses is how they react during times of stress, such as when the temperature gets ...

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.

Stem cells age faster and become functionally exhausted in low Earth orbit, making crewed long-duration space travel even more challenging. When you purchase through links on our site, we may earn an ...

Mice have remained the focal point for life sciences research for the past several decades. Their universality in biomedicine ...

You might feel the same every day, but biologically, you never are. Beneath the surface, your body is constantly rebuilding ...

A human cell is a Rube Goldberg machine like no other, full of biological chain reactions that make the difference between life and death. Understanding these delicate relationships and how they go ...

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 ...

Researchers can use it to test how well antiviral drugs work directly in living cells and see the results in real time. The team also points out that the same tool could be used to study how other ...
