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 ...

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

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 ...

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 ...

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.

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 ...

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 ...

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 ...

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 ...
