Scientists have identified a gene responsible for the formation of enamel, which is the key component of the teeth. The experiments were accomplished in mice carrying a deletion of the transcription factor Tbx1, a gene that plays a principal role in several human malformations (heart, thymus, parathyroid, face, and teeth) associated to the DiGeorge syndrome.

Disrupting the function of a key molecule in the brain leads to microscopic brain abnormalities and schizophrenia-like behavior in mice. These abnormalities are similar to those seen in the autopsied brains of people who diagnosed with schizophrenia in life, according to a scientists.

Exciting recent developments in stem cell research have revealed how specialized cells, such as skin cells, can be reprogrammed into pluripotent stem cells (iPS cells) that can form all the body’s tissues. But the reprogramming techniques currently in use rely on potentially harmful viruses to deliver the reprogramming factors required for this change. Now stem [...]

New research suggests that weight-loss campaigns that promote exercise may actually cause people to eat more. People who viewed posters suggesting that they “join a gym” or “take a walk” ate more food after looking at the posters than people who saw similarly designed posters prompting them to “make friends” or “be in a group,” [...]

UK astronomers, using a telescope aboard the NASA Swift Satellite, have captured information from the early stages of a gamma ray burst — the most violent and luminous explosions occurring in the Universe since the Big Bang.

Women who have more years of fertility (the time from first menstruation to menopause) have a lower risk of developing Parkinson’s disease than women with fewer years, according to a large, new study.

Very large and abrupt changes in temperature recorded over Greenland and across the North Atlantic during the last Ice Age were actually global in extent, according to new research. The research supports the idea that changes in ocean circulation within the Atlantic played a central role in abrupt climate change on a global scale.
According to a new study, the frequency of regulatory T-cells (Treg) correlates to the severity of inflammation in allergic asthma, suggesting that Treg may play an important role in asthma pathogenesis.
