The human body is made up of trillions of cells that perform functions from skin protection to muscle movement. Cells can ...

A central question in molecular biology is how cells protect their chromosomes from damage during repeated cell division. At ...

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 ...

Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed.

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 ...

Immunotherapy has been one of the most transformative treatments for cancer patients in recent decades, shifting the emphasis ...

A new study by physicists and neuroscientists from the University of Chicago, Harvard and Yale describes how connectivity among neurons comes about through general principles of networking and ...

The regulatory division of the immune system is vital for its overall function. Immune T cells originate in the bone marrow and then travel to the thymus—a kind of biological police academy. 2 Here, ...
