Oxytocin, a hormone involved in child-birth and breast-feeding, helps people recognize familiar faces, according to new research in the January 7 issue of The Journal of Neuroscience. Study participants who had one dose of an oxytocin nasal spray showed improved recognition memory for faces, but not for inanimate objects.

Stem cells are the body's primal cells, retaining the youthful ability to develop into more specialized types of cells over many cycles of cell division. How do they do it? Scientists at the Carnegie Institution have identified a gene, named scrawny, that appears to be a key factor in keeping a variety of stem cells in their undifferentiated state.

Pterosaurs have long suffered an identity crisis. Pop culture heedlessly — and wrongly — lumps these extinct flying lizards in with dinosaurs. Even paleontologists assumed that because the creatures flew, they were birdlike in many ways, such as using only two legs to take flight.

Two children have a seizure. One child never has another seizure. Twenty years later, the other child has a series of seizures and is diagnosed with epilepsy. A study being led by researchers at Rensselaer Polytechnic Institute is looking at what could possibly happen in the development of these two children that would lead to such extreme variations in their neurologic health.

Women who smoke during pregnancy risk delivering aggressive kids according to a new Canada-Netherlands study published in the journal Development and Psychopathology. While previous studies have shown that smoking during gestation causes low birth weight, this research shows mothers who light up during pregnancy can predispose their offspring to an additional risk: violent behaviour.

German battlefield yields Roman surprises
Archaeologists have found more than 600 relics from a huge battle between a Roman army and Barbarians in the third century, long after historians believed Rome had given up control of northern Germany. The artifacts are so well preserved that the scientists can already retrace some of the battle lines.
