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 ...

Mesenchymal drift may help explain how cells lose stable identity and acquire pro-fibrotic, inflammatory mesenchymal traits ...

Living cells cool much slower than our current understanding of heat conduction can explain, according to new research from the University of Tokyo. Researchers have used two techniques—high-speed ...

Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

Cilia are ubiquitous on cells, playing a variety of roles, Dr. Nicastro explained. While non-motile cilia serve as sensors for chemical and mechanical signals, motile cilia rhythmically beat to propel ...

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 ...

Researchers at Trinity College Dublin have identified key differences in how immune cells generate and use energy, a process known as cellular metabolism, in people with latent versus active ...

Scientists discovered a unique moss protein called RAK1 that combines two important cellular functions into one molecule.

Growing older affects every part of the body, including the brain. Many people notice changes in memory, concentration, and mental sharpness as they age. Scientists have long known that aging ...

CAMBRIDGE, MA -- The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and send information and commands throughout the brain and ...
