ReWalk is the first FDA-approved personal exoskeleton

If you're still not used to seeing electric wheelchairs, robotic prosthetics, and other forms of hi-tech assistive technology in public places, it would be best to catch up with the times as a new one just joined the list. The US Food and Drug Administration has just given the thumb up to the ReWalk Personal exoskeleton, paving the way for similar machines that will help those who have lost mobility to get back on their feet.

NASA's "flying saucer" has had a wet but happy landing, with the Low-Density Supersonic Decelerator (LDSD) finally taking to the skies after several launch delays, and giving positive early signs for potential future Mars technologies. The Saturday flight took place in Hawaii, with the distinctive saucer-shaped craft being dropped 120,000 feet above the Pacific Ocean and then taking thirty minutes to descend into the waves.

Big Bang breakthrough hits dust doubts

Scientists responsible for a "spectacular" discovery earlier this year that could explain Big Bang theory and how the universe was created now admit their evidence may just have been cosmic dust. A Harvard team of physicists announced back in March that it believed it had observed the effects of rapid expansion that would follow the sudden creation of our universe, but the study has gained a vital disclaimer at publication.
