Cells were long believed to safeguard nuclear contents, releasing them only during cell death. Extracellular DNA was thought ...

Even in death, cells leave a trace. Scientists have discovered a microscopic “Footprint of Death” that not only helps the immune system clean up but can also give viruses a new way to spread infection ...

Add Yahoo as a preferred source to see more of our stories on Google. Drosophila wing A new study reveals some surprising discoveries about healing processes that are potentially triggered by the ...

Researchers in Japan have identified a striking new way immune cells strip DNA out of dying neighbors, a process they call ...

The duplication and division of cells is critical to keeping all multicellular organisms alive. But the opposite process is equally important: cell death. Controlled death of cells, or programmed cell ...

As the brain ages, it loses cells. Researchers have predominantly focused on the effects of cell death in brain areas responsible for cognition, but the cerebellum, most well-known for coordinating ...

Every day, the human body removes billions of dead cells. 1 Professional phagocytes, such as macrophages and dendritic cells, do a lot of the heavy lifting, but some non-immune cells, the so-called ...

When cells are about to die, they send signals that trigger proteins which are supposed to destroy them, but it doesn’t always happen that way. Some cells activate the signal but then resist the ...

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger. When the sun shines on your skin, what does it hit? When it causes a ...

After treating a tumor with chemotherapy and radiotherapy, cells known as senescent cells can appear. These are cells that do not divide, are involved in the aging process and are resistant to cell ...
