Proteins long known to be essential for hearing have been hiding a talent: they also act as gatekeepers that shuffle fatty molecules across cell membranes. When this newly discovered function goes ...

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 ...

Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that ...

Chemists discover how key contrast agent works, paving a way to create new markers needed for correlative microscopy that can image the structure and signaling of cells at the same time. Two labs at ...

Cancer is a disease that causes abnormal cells to reproduce and spread to other parts of the body, which can result in tumors or damage to the immune system that may become fatal. Healthy cells follow ...

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, ...

Weight loss is notoriously hard to maintain. Within a few years most people regain the pounds they initially lose, whether ...

Researchers have found that a deeper look at proteins and cells may help explain why prostate cancer tumors often become resistant to hormone therapy. Researchers found that looking at cell patterns ...

Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in ...

A cell model that replicates the structure and function of the human intestine has been developed, creating an evaluation platform capable of more accurately predicting adverse effects of new drugs.

Parkinson's disease is associated with toxic clumps of the alpha-synuclein protein in the brain, which disrupt healthy cell communication. Now, a new study shows another way this protein may damage ...

Why are humans active during the day when many mammals thrive at night? New research [1] published in Science suggests the answer lies deep within our cells.Early mammals were nocturnal, avoiding ...
