Shall We Dance? Robots Offer A Hand On The Ballroom Floor - SpaceDaily        Japanese researchers have developed a robot capable of taking to the floor by predicting how its human partner will move. The Partner Ballroom Dance Robot -- or PBDR in robot talk -- has a woman's face, a sensor around its waist and can move in all directions on its three wheels hidden underneath an evening gown. As its partner takes steps, the robot analyzes his movements and figures out how to accompany him with its shoulders, elbows, waist and neck. The robot is 165 centimeters (five feet, six inches) tall and weighs 100 kilograms (220 pounds), with a male version under development. The robot's developer, Dr. Kazuhiro Kosuge, with Tokohu University, acknowledged the robot did not yet have movements as sharp or as wide to match the dancing steps of humans. But PBDR is a step in another direction -- developing a robot that can care for the elderly.
Gym Six minutes of sweat a week might be enough to keep fit  - BBC  Keeping fit and healthy may not require hours of physical exercise every week, research suggests. Canada's McMaster University found just six minutes of intense exercise a week could be as effective as six hours of moderate activity. However, experts warn it might be too much for people not already fit. One group cycled for two hours a day at a moderate pace, and a second cycled for 10 minutes a day in 60-second bursts, at a slightly harder pace. A third group took part in sprint training - cycling at top speed for two minutes in 30 second bursts with four minutes rest between each sprint. All three groups were found to have improved to the same extent. 

Ebola ward

Ebola, Marburg vaccine 'success'  - BBC  The first vaccine to protect monkeys against Ebola and Marburg viruses has been developed by scientists from Canada, the United States and France. Scientists adapted another type of virus to carry proteins from the Ebola and Marburg viruses. This modified virus was injected into macaque monkeys who were later exposed to the disease-causing pathogens. Just a single injection completely protected the monkeys. The initial data is so encouraging say the researchers that the technique could be used against other emerging viruses and may even lead to a trial vaccine being developed for humans
