In many species including humans, the cells responsible for reproduction, the germ cells, are often highly interconnected and share their cytoplasm. In the hermaphrodite nematode Caenorhabditis elegans, up to 500 germ cells ...

(Phys.org)—A team of researchers in South Korea has developed a method to cause cell death in both living fish and lab bowel cancer cells (in vivo and in vitro) using a magnetic field. The application of the magnetic field, ...
A protein designed by researchers at Georgia State University can effectively target a cell surface receptor linked to a number of diseases, showing potential as a therapeutic treatment for an array of illnesses, including ...

This week, we looked at the swirling chaos around supermassive black holes, anthropogenic climate effects over the Atlantic ocean and the threats to koalas.
In animals that reproduce by internal fertilization, as humans do, you'd think a penis would be an organ you couldn't really do without, evolutionarily speaking. Surprisingly, though, most birds do exactly that, and now researchers ...

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.
