Study of homicidal tribe shows aggressive warriors have less reproductive success
Scientists now have an experimental answer to the question of how cells move during biological processes as diverse as the development, metastasis, or regeneration of tissues. The work addresses the issue of collective mobility of cells, that is to say, how cells are moved within tissues, and what is the prevalent form of movement inside [...]

How can we produce pigs that provide us with healthy and yet good tasting meat? Meat eating quality and healthiness are closely related to the amount and type of fat. During the last decade there has been extensive selection towards leaner genotypes which has resulted in reduction of not only undesirable subcutaneous fat, but also [...]

For more than a decade, scientists have been frustrated in their attempts to create continuously emitting light sources from individual molecules because of an optical quirk called “blinking,” but now scientists have uncovered the basic physics behind the phenomenon and created a nanocrystal that constantly emits light.

In the world of small things, shape, order and orientation are surprisingly important, according to findings from a new study. Chemists used computer simulations to study a very simple model of molecules on surfaces, which looks a lot like the computer game “Tetris.”
