Diets consisting of fewer calories improve cell performance

The number of calories a person eats directly influences the performance of cells. A group of researchers from the University of São Paulo (USP) has shown that low-calorie meals have a protective effect against some diseases. ...

Why too much DNA repair can injure tissue

DNA-repair enzymes help cells survive damage to their genomes, which arises as a normal byproduct of cell activity and can also be caused by environmental toxins. However, in certain situations, DNA repair can become harmful ...

New role for death molecule

Cellular death is vital for health. Without it, we could develop autoimmune diseases or cancers. But a cell's decision to self-destruct is tightly regulated, so that it only happens to serve the best interests of the body. ...

Diabetes

Our bodies may cure themselves of diabetes in the future

Diabetes is the inability to produce insulin, a hormone that regulates blood sugar levels, due to damaged or non-existing insulin cells. Many diabetes patients take insulin supplements to regulate these levels.

Losing neurons is sometimes not all bad

Current thinking about Alzheimer's disease is that neuronal cell death in the brain is to blame for the cognitive havoc caused by the disease. But a new study suggests that neuronal death may actually be a protective reaction ...

Programmed cell death

Programmed cell-death (or PCD) is death of a cell in any form, mediated by an intracellular program. In contrast to necrosis, which is a form of cell-death that results from acute tissue injury and provokes an inflammatory response, PCD is carried out in a regulated process which generally confers advantage during an organism's life-cycle. PCD serves fundamental functions during both plant and metazoa (multicellular animals) tissue development.
