People need to sleep, and sleep deprivation can cause many changes in the brain. But we have a poor understanding of why sleep is so crucial. New research has examined a fruit fly model to assess how ...

Researchers at Oregon Health & Science University have identified a previously unknown system inside cells that works like ...

Scientists have discovered that cells can sense far beyond the surfaces they touch. While individual cancer cells can probe about 10 microns ahead by tugging on surrounding collagen fibers, clusters ...

Aging does not arrive all at once. It builds quietly across years, touching cells long before symptoms appear.

- What is the immune system? The immune system is your body's first line of defence against invaders such as microbes that could give you an infection. Its most powerful weapons are white blood cells ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Cells can be thought of as cities, with factories, a transport system, and lots of building activity. An international team ...

Cells aren’t as passive as scientists once thought—they actively create internal currents to move proteins quickly and efficiently. These “cellular winds” push materials to the front of the cell, ...
