Cheetah is a four-legged robot that has attained the highest land speeds yet of any robot with legs.
The Cheetah, developed by Boston Dynamics, mimics the movements of the real animal and uses hydraulic pumps and a boom to get it running. A free-running version is slated for tests later this year, and Boston Dynamics also makes other robots which can carry heavy loads and carry out surveillance, creating the potential to aid the handicapped and to enhance our collective security.

The climate change we're witnessing is more dramatic than we might think.
A lazy buzz phrase – 'Is this the new normal?' – has been doing the rounds as extreme climate events have been piling up over the past year. To which the riposte should be: it's worse than that – we're on the road to even more frequent, more extreme events than we saw this year.
Once again, our circadian rhythm points the way.
