When HHMI Investigator Amita Sehgal started studying sleep 25 years ago, the topic elicited a yawn from most biologists. "In ...

MIT researchers have found that tiny DNA loops persist even as cells divide, challenging the idea that the genome resets during mitosis. These structures may explain how cells retain genetic ...

Human cells are extremely small and tightly packed – at about 20 micrometers across, roughly one-fifth the width of a human hair, each cell contains a dense mix of proteins, organelles, and molecular ...

Researchers at the Icahn School of Medicine at Mount Sinai have discovered how to reverse aging in blood-forming stem cells in mice by correcting defects in the stem cell's lysosomes. The breakthrough ...

Researchers have uncovered a shared brain cell breakdown mechanism behind Alzheimer’s and Parkinson’s diseases, revealing how two different proteins can disrupt neurons in the same devastating way.

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

The new ‘COPILOT’ function uses AI to generate summaries, tags, tables, and more based on a group of cells. The new ‘COPILOT’ function uses AI to generate summaries, tags, tables, and more based on a ...

The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

The eukaryotic genome is organized in the form of a highly compact nucleoprotein complex, the chromatin. Nucleosome, the basic unit of chromatin, consists of ~147 bp of DNA wrapped 1.65 times around a ...
