Two new studies from Johns Hopkins University are providing scientists with an unprecedented view of how human cells repair one of the most dangerous forms of genetic damage: a break that severs both ...

At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, particularly in tissues such as the bone marrow, intestine and skin; neurons and heart ...

Our cells accumulate DNA mistakes as we age, eating less slowed that process in mice Every cell carries a molecular record of time. As DNA is copied, repaired and exposed to damage, mutations ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Beyond amyloid plaques and tau tangles, scientists find Alzheimer's disrupts the 3D folding of DNA inside brain cells.

Understanding gene regulation may be key to interpreting human disease genetics. Genes are regulated in part by stretches of ...

Learn how DNA can be exchanged between two cells that connect by forming nanotubes, and find out why this is crucial for cancer research. When cells in our body are going through a rough patch due to ...

Activated immune cells secrete tiny capsules bearing DNA that can enter other immune and tumor cells to stimulate the body's defense systems, according to a study led by investigators at Weill Cornell ...

Sucralose, the artificial sweetener used in Splenda, came under scrutiny after a study found that a related chemical damaged ...
