Was The Sony Hack Actually An Act Of Cyberwar? — It is hard to concisely describe how strange our cyberpunk present is. Yesterday Sony announced it wouldn't be releasing "The Interview," a rather raunchy film that features the assassination of Kim Jong-Un. The decision to pull the film came after hackers released tons of Sony's internal emails and documents to the public, and then threatened attacks if the film was released, maybe even on theaters showing the movie.

NASA Envisions A Cloud City Above Hellish Surface Of Venus — The planet Venus, named for the Roman goddess of Love, certainly wouldn't be a very loving place to live. On the surface, Venus hosts scorching temperatures of more than 800 degrees Fahrenheit, a heat capable of melting lead, as well as an atmospheric pressure 92 times greater than Earth's.

Will Silicon Valley Transform Farming? — At this point, Silicon Valley's promise to Change the World or Make the World a Better Place or any other iteration is more of a punch line than a catchphrase, especially with criticisms that range from abuse of customers' privacy, to industry-wide sexism, to economic division.

World First: Man Controls Two Prosthetic Arms With His Mind — Until recently, losing both arms in an accident would probably have meant the end of a patient's two-fisted grip. Not so for Leslie Baugh, the first shoulder-level double amputee to wear and control two complex, mind-controlled prosthetic limbs. Baugh isn't the first person to control robotic limbs with his mind.

Watch An iPad Land An Airplane [Exclusive] — High above rural Arkansas, I'm jammed in the back of a small four-seat airplane. Andrew Barker pilots the aircraft while Austin Meyer sits beside him. Everything is going great-until the engine suddenly quits at 5,000 feet. With a quick tap on his iPad, Meyer, creator of the popular flight simulator X-Plane, summons his app Xavion to rescue us.

What To Expect In 2015: General Relativity Gets Put To The Test — Over the course of four Thursdays in November 1915, Albert Einstein stood before the Prussian Academy in Berlin and unveiled a set of equations that upended our ideas about space and time. A century later, his grand project remains frustratingly incomplete.

Microscope Uses Holograms Instead Of Lenses To Diagnose Disease — A new prototype microscope doesn't use lenses to magnify objects. Instead, it makes holograms that a computer digitally records and magnifies. The result is a microscope that's cheaper and easier to use than traditional, lens-based microscopes. Research groups have made instruments like these before. They're called digital holographic microscopes.

Years Of Chinese Air Pollution Data Captured In Swirling Charts — Xiaoji Chen set out to find patterns in the air pollution that plagues Chinese cities. Using data from the country's Ministry of Environmental Protection, she created spirals that reveal the annual cycles of winter air pollution and spring sandstorms. The year 2000 appears at the center and 2013 at the outer edge, with the more severe pollution in red.

What To Expect In 2015: Robots Join The Open-Source Revolution — Three of the most sophisticated robots ever built- NASA's Robo­naut 2, Rethink Robotics' Baxter, and Boston Dynamics' Atlas -have one thing in common: They all run on the Robotics Operating System (ROS), open-source software that's rapidly becoming the Android of robotics. Why is this significant?

How 3-D Printing Made The Perfect Prosthetic Legs For Derby The Dog — You should see this dog run. Derby was born with deformed front legs, but recently received a pair of 3-D printed prosthetics, which he is quite good at maneuvering in: 3-D printing experts often talk about how helpful printers are for rapid prototyping. That turned out to be true in Derby's case.

Satellite Images Show How Much More Light Americans Use During The Winter Holidays — 'Tis the season to use way more electricity than you normally would. U.S. cities use so much more light at night during December that the difference can be seen by satellite. U.S. suburbs emit 30 percent to 50 percent more light during the winter holidays, while urban areas emit 20 percent to 30 percent more light, a NASA analysis found.
