In decisions about where to eat, baboons don’t all have an equal say, according to a new report. Rather, most baboons in a group will follow their leader to a dining spot of his choosing, even if it means a considerably more meager meal for themselves than they could have had otherwise.

Islet cell transplantation is a promising therapy for people with type 1 diabetes, but it requires a regime of powerful immunosuppressive drugs so the immune system won’t reject the insulin-producing islets. The drugs raise the risk of infections and cancer and are toxic to the islets themselves. Researchers have developed a new technique that eliminated [...]

Wireless experts believe that, by 2017, personal networks will have to cope with at least a thousand devices, like laptops, telephones, mp3 players, games, sensors and other technology. To link these devices will require a ‘Network of Everything’. It represents an astonishing challenge, but European researchers believe that they are moving towards the solution.
The Plague of Athens is one of 10 historically notable outbreaks described in an article in The Lancet Infectious Diseases. The phenomenon of widespread, socially disruptive disease outbreaks has a long history prior to HIV/AIDS, severe acute respiratory syndrome, H5N1 avian influenza and other emerging diseases of the modern era, note the authors.

Scientists using ESA’s Mars Express have produced the first crude map of aurora on Mars. These displays of ultraviolet light appear to be located close to the residual magnetic fields generated by Mars’s crustal rocks. They highlight a number of mysteries about the way Mars interacts with electrically charged particles originating from the Sun.

How does a swarm of bees find its way to a new nest site when less then 5 percent of the community knows the way? Filming bee swarms as they relocated to new nest site and analyzing the insects’ apparently chaotic course, scientists have found that “streaker” bees fly through the swarm at high speed [...]
