Altruism in bacteria: Colonies divide the work

Bacteria found in soil specialize in the colony by division of labor. Some of the bacteria produce antibiotics, even when it comes at the expense of their individual reproduction success, to defend their colony against competitors.

Plant organ growth is not so different from animals

For a long time, researchers assumed that cell death occurs mainly during animal organ growth, but not in plant organs. A research group led by Hannele Tuominen from UPSC has now demonstrated that the death of certain cells ...

Study finds salt nanoparticles are toxic to cancer cells

A new study at the University of Georgia has found a way to attack cancer cells that is potentially less harmful to the patient. Sodium chloride nanoparticles—more commonly known as salt—are toxic to cancer cells and ...

Bacteria can 'outsmart' programmed cell death

Certain bacteria can override a defence mechanism of the immune system, so called programmed cell death, through inhibition of death effector molecules by their outer membranes components. Shigella bacteria, which cause diarrhoea, ...

The good side of carbon monoxide

Most people think of carbon monoxide as harmful, and with good reason—the colorless, odorless gas sends 50,000 people in the U.S. to hospitals each year when their furnaces malfunction or car engines run in poorly ventilated ...

Cells control their dance of death

La Trobe University researchers have revealed for the first time how white blood cells control the final moments of their death, helping their own removal from the human body.

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.
