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 ...

Every cell in your body runs on a currency called ATP, and the factories that mint it are mitochondria. For decades, ...

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 ...

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 ...

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 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 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 ...

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 ...

Blood cells carry a deep evolutionary history. A new analysis suggests their earliest ancestors were macrophage-like cells inherited from single-celled life.
