University of Pittsburgh scientists are unlocking the complexities of a recently discovered cell death process that plays a key role in health and disease, and new findings link their discovery to ...

Metacaspases, ancestral homologues of the caspase family, are pivotal cysteine proteases found in a wide range of unicellular organisms, including yeasts, algae, and phytoplankton. These enzymes ...

Illustration of a healthy cell (left) alongside a cell that has been affected by necrosis (right). The process of necrosis, a form of cell death, may represent one of the most promising ways to change ...

In Alzheimer's, brain cells die too soon. In cancer, dangerous cells don't die soon enough. That's because both diseases alter the way cells decide when to end their lives, a process called programmed ...

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 ...

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

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 ...

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

Add Yahoo as a preferred source to see more of our stories on Google. DARE cells When tissue is severely damaged, surviving cells can respond in a concentrated burst of biological repair known as ...

Recent scientific breakthroughs suggest that manipulating a hidden “death switch” in our cells could significantly slow the aging process. This discovery, coupled with findings that caffeine can ...
