A bizarre spherical cloud was spotted hovering over a city in Japan last week. Now, alien hunters believea 'Death Star' (bottom inset) UFO created the puff to hide - allowing it to observe humans without being seen.

The robotic arm you can control with your MIND: Researchers unveil radical technology that could transform life for people with disabilities
Scientists have created a ‘brain-computer interface’ that allows people to control a robotic arm using only their mind. The system uses advanced signal processing and machine learning to convert ‘thoughts’ into actions, allowing them to reach and grasp objects without ever lifting a hand. Researchers say it’s the first time this has been done without the use of a brain implant – and the technology could one day be used to help people who are paralyzed or have neurodegenerative diseases.

A hypnotic new 3D visualization reveals the swirling patterns of carbon dioxide as it travels around the world. The simulation revealed today by NASA shows how concentrations of the greenhouse gas fluctuated between September 2014 and September 2015. The data could help scientists to answer critical questions on where these emissions are absorbed by the land and ocean, and how these areas will continue to carry out this role as CO2 rises.
A Belgium firm has designed a robot that prints out perfectly sized boxes to ship your gifts. Called Slimbox, users measure their product, select the type of box and enter the dimensions using the accompanied app. The machine uses laser cutters to create a template (top inset) for a foldable box (bottom inset) on a piece of cardboard, which it prints out in moments.
Shipwreck of the lost Schiedam is found AGAIN: Divers rediscover the 17th century vessel in the same spot as the wreck from TV drama Poldark
Divers have rediscovered a 17th century shipwreck off Cornwall, at exactly the same spot where the shipwreck scene was filmed in 2014 for the TV series Poldark.

The incredible moment that a man solves a Rubik’s cube in less than FIVE SECONDS to set a new world record (as the previous champion sits next to him and grins through gritted teeth)
The footage, shot in Sydney, Australia on Sunday, shows Feliks Zemdegs (pictured), 20, solving the famous 1980s Rubiks cube toy in just 4.73 seconds. The previous world record was set by Mats Valk (right), 20, who is sat next to Mr Zemdegs as he breaks his record. Mr Zemdegs, a commerce student at the University of Melbourne, gets just ten seconds to inspect the Rubiks cube before he has to solve it.
