A 10th of children have a "monkey-like" immune system that stops them developing AIDS, a study of Oxford University suggests. The study, in Science Translational Medicine, found the children's immune systems were "keeping calm", which prevented them being wiped out.An untreated HIV infection will kill 60% of children within two and a half years, but the equivalent infection in monkeys is not fatal. The findings could lead to new immune-based therapies for HIV infection. The virus eventually wipes out the immune system, leaving the body vulnerable to other infections, what is known as acquired human immunodeficiency syndrome (AIDS). The researchers analysed the blood of 170 children from South Africa who had HIV, had never had antiretroviral therapy and yet had not developed AIDS.

A journey inside Bern’s whimsical clock tower reveals how clicking gears and dancing bears changed the meaning of time. Deep inside a medieval watchtower, Markus Marti presides over the passage of time. Several times a week in the heart of Bern, Switzerland, the retired engineer leads a small group of visitors up a twisting narrow staircase. Then, using a wooden baton as a pointer, he explains how a maze of iron parts powered by a swinging pendulum has, second by second, counted off the last half millennium.
