How Rhesus Macaques and Humans have conquered the world

When it comes to their social behavior, people sometimes act like monkeys, or more specifically, like rhesus macaques, a type of monkey that shares with humans strong tendencies for nepotism and political maneuvering, according to research by Dario Maestripieri, an expert on primate behavior and an Associate Professor in Comparative Human Development and Evolutionary Biology at the University of Chicago.

New stem cells by reprogramming

Researchers are discovering new ways to help ‘de-program' specialised cells so that they can be re-programmed to form a range of different types of tissue, an international meeting of stem cell biologists was told.

Study identifies pathway required for normal reproductive development

Massachusetts General Hospital (MGH) clinical researchers, in collaboration with basic scientists from the University of California, Irvine (UC Irvine) have identified a new molecular pathway required for normal development of the reproductive, olfactory and circadian systems in both humans and mice.

Simplest circadian clocks operate via orderly phosphate transfers

Researchers at Harvard University and the Howard Hughes Medical Institute have found that a simple circadian clock found in some bacteria operates by the rhythmic addition and subtraction of phosphate groups at two key locations on a single protein.

H5N1 able to pass through placenta to fetus and infect organs other than lungs in adults

The H5N1 strain of the bird flu virus can pass through the placenta of pregnant women to the unborn fetus, and can infect organs other than the lungs in adults. These are the conclusions of authors of an Article in The Lancet.

Scientists isolate stem cells in womb tissue

Scientists in Australia have found a way of identifying probable stem cells in the lining of women's wombs. The finding opens up the possibility of using the stem cells for tissue engineering applications such as building up natural tissue to repair prolapsed pelvic floors.
