Nissan says its autonomous car will be ready for sale to consumers by 2020.

Nissan Motor Co. is aggressively pushing forward with plans for a mostly autonomous car that will be ready for sale to consumers by 2020, putting it well ahead of its global competitors.

Chief Executive Carlos Ghosn said the technology would be ready by the Japanese auto maker’s self-imposed deadline—though he wasn’t sure if it would be legal on any nation’s roads.

“We are very excited about it and we want to come as soon as…

Who needs a peep hole when a wifi network will do? Researchers from MIT have developed technology that uses wireless signals to see your silhouette through a wall—and it can even tell you apart from other people, too.

The team from MIT’s Computer Science and Artificial Intelligence Lab are no strangers to using wireless signals to see what’s happening on the other side of a wall. In 2013, they showed off software that could use variations in wifi signal to detect the presence of human motion from the other side of a wall. But in the last two years they’ve been busy developing the technique, and now they’ve unveiled the obvious — if slightly alarming — natural progression: they can use the wireless reflections bouncing off a human body to see the silhouette of a person standing behind a wall.

Not only that, the team’s technique, known is RF-Capture, is accurate enough to track the hand of a human and, with some repeated measurements, the system can even be trained to recognise different people based just on their wifi silhouette. The research, which is to be presented at SIGGRAPH Asia next month, was published this morning on the research group’s website.

The novel its a bit older, but it‘s an incredible vision!

When Star Trek’s Scotty warns the Captain that the engines can’t “take it”, he might just be best off switching fuel — a new book claims that humanity could reach the stars using vast spacecraft harnessing the energy of black holes with the power to “eat planets”.

Inside would be an artificial black hole — created by spheres of generators firing “gravitons”- and, claims author Dr Roger Hoskins, Fellow of the Royal Astronomical Society, would curve space-time — and would be “faster than anti matter drives.”

Captain Kirk would be jealous of the speeds offered by a black hole powered craft — which displaces or curves space time, like a warp drive, thus appearing to go faster than light.
