Botox, is best known as one of the most commonly used molecules to reduce wrinkles. It is also known as one of the most poisonous naturally occurring substances. Now, after new research, it has become an effective method to save newborns suffering from CHARGE Syndrome from devastating tracheotomies.
Take a deer's body, attach a camel's head and add a Jimmy Durante nose, and you have a saiga -- the odd-ball antelope with the enormous schnoz that lives on the isolated steppes of Central Asia.
Human diseases and social networks seem to have little in common. However, at the crux of these two lies a network, communities within the network, and farther even, substructures of the communities. Computer scientists and geneticists can now use a new computer program to automatically discover communities and their subtle structures in a variety of networks.
Researchers have found a process in the brain that may help explain the link between Alzheimer's and stroke. This finding connects the dots between a peptide called p25 and increased production of amyloid beta. This newly identified p25/cdk5 pathway could explain why the risk of Alzheimer's disease is significantly higher following a stroke.
If the battle against HIV, the virus that causes AIDS, is a chess match, then new research published today gives new insight into one of the virus' most important moves. The findings reveal information about how a critical genetic switch in the virus operates. When HIV infects an immune cell, it can enter one of two states: activation, where the virus replicates and then destroys the host cell; and latency, where the viral genetic material continues to exist in the cell, but there is no production of additional virus.
Computing grids have helped scientists shed light on how life on earth may have originated. Deep ocean hydrothermal vents have long been suggested as possible sources of biological molecules such as RNA and DNA but it was unclear how they could survive the high temperatures and pressures that occur round these vents.
COLOMBO (Reuters) - Pioneering science fiction writer and visionary Arthur C. Clarke, best known for his work on the movie "2001: A Space Odyssey", has died in his adopted home of Sri Lanka at the age of 90.

According to researchers, fruit flies are more like humans in their responses to many sweet tastes than are almost any other species, including some species of monkeys. The findings demonstrate the critical role of environment in shaping the evolution of taste preferences and feeding behavior.
Doctors may one day be able to detect early stages of colon cancer without a biopsy, using a new technique. The imaging technology is one of many new ways of detecting cancers in the body in real time.
Researchers have estimated that one in six women are at risk for developing Alzheimer's disease in their lifetime, while the risk for men is one in ten. Stroke and dementia are the most widely feared age-related neurological diseases, and are also the only neurological disorders listed in the ten leading causes of disease burden.
Endangered sea turtles are victims of sloppy logging practices in the west central African country Gabon, according to a new study. Sea turtle nesting attempts are impeded by lost or abandoned logs that accumulate along the country's coastal beaches. Logs are floated downriver from forests to coastal lumberyards in the Gabonese Republic, but some float out to sea and then wash ashore, where they form large tangles.
