A man has been able to move all four of his paralysed limbs with a mind-controlled exoskeleton suit. The 65kg of sophisticated robotics is not completely restoring function. However, it is a marked advance on similar approaches that allow people to control a single limb with their thoughts.

A new “anti-solar panel” could be able to bridge the gap left by solar energy, collecting energy from the night sky. The thermoelectric generator-based device, developed by a team of researchers at Stanford University in Palo Alto, California, harnesses the variance in temperature between Earth and outer space, by using “a passive cooling mechanism known as radiative sky cooling to maintain the cold side of a thermoelectric generator several degrees below ambient” according to the researchers study, published in the scientific journal Joule.

A new algae bioreactor can suck as much carbon dioxide out of the atmosphere as roughly an acre of forest — potentially giving dense cities a new weapon in the fight against catastrophic climate change.
