If you use a lock screen pattern to protect your Android phone, it's a lot less secure than you might think.

That's the message from researchers at the University of Lancaster, who have put out a paper explaining how they were able to reconstruct people's lock screen patterns with a high degree of accuracy by using discretely captured footage. (You can check out the full study below.)

Researchers at MIT have found a way to make one of the world’s strongest materials even stronger. Graphene, a two-dimensional form of carbon that gets its strength from a unique honeycomb structure, was made even more durable by compressing and fusing it into a 3D sponge-like configuration. The ultralight material has a density of just five percent, but could be as much as 10 times stronger than steel.

While governments around the world continue the long, hard work of regulating away the future use of fossil fuels, scientists have discovered how to remove carbon dioxide already in the atmosphere. Researchers at the Oak Ridge Laboratory unexpectedly discovered a chemical reaction that converts carbon dioxide into ethanol. This discovery was made as the researchers attempted to uncover a series of chemical reactions that could turn CO2 into fuel. As it turned out, the first step in this series of reactions was quite enough to make it happen. The resultant ethanol is a cleaner fuel that could be used power generators or vehicles.

Researchers at Stanford University have developed a smartphone microscope that allows kids to play games or make more serious observations with miniature light-seeking microbes called Euglena.

"Many subject areas like engineering or programming have neat toys that get kids into it, but microbiology does not have that to the same degree," said Ingmar Riedel-Kruse, Assistant Professor of Bioengineering.

Everywhere you go on the web, trackers are working to reconstruct your every move. But who tracks the trackers? That’s just what researchers at the University of Washington are doing, with purpose-built tools and liberal use of Internet Archive’s Wayback Machine.
