An Experiment Could Determine Whether Gravity Is Quantized

Sat, 17/10/2015 - 2:27pm
TheAlexKnapp writes: Physicist Brian Koberlein explains an experimental proposal by Großardt et al, which would attempt to determine whether gravity is quantized. "Their idea," explains Koberlein, "is to take a charged disk of osmium with a mass of about a billionth of a gram and suspend it an electric field. This is small enough that its energy levels in the electric field would take on quantum behavior when cooled to temperatures a fraction of a Kelvin above absolute zero, but its also massive enough that its gravitational pull would affect the quantum behavior." The two primary approaches to a quantum gravity, the "perturbative approach" and "the semi-classical method," predict different results from this type of interaction. So the results of the experiment, could, in principle, elucidate the right approach for developing future theories of quantum gravity.

Yahoo Mail Moves From Passwords To Push Notification Sign-Ins

Sat, 17/10/2015 - 1:29pm
An anonymous reader writes: A revamp of Yahoo Mail includes a new feature which eliminates the password from the sign-in process on mobile platforms, instead relying on the user's phone number as a token of authenticity. Notification-based sign-ins are a network-heavy commitment used with less frequency during some online banking authentication procedures, and by Google and others in specific events such as the need for a password reset. But Yahoo is well-motivated to improve security after a 2014 data breach led to a mass-reset of passwords for affected users.

China Looks To Deep Space Missions, Including More Lunar Landings and Robot Ants

Sat, 17/10/2015 - 12:27pm
MarkWhittington writes: China has already landed a rover on the moon and has launched numerous crewed space missions in low-Earth orbit. It is looking ahead to building a space station and landing more probes on the moon, including the lunar farside. According to a story in Xinhua, the Chinese are already looking beyond to deep space missions to destinations including the moon, Mars, and asteroids. The idea is that China will not be a respected space power until it starts accomplishing things in space that no other country has done before.

Data Centers Coming To a City Near You

Sat, 17/10/2015 - 9:12am
1sockchuck writes: There are more wired businesses than ever in towns and cities across America. That's why the data center industry is coming to smaller cities you may not think of as technology hubs. Industry executives say the convergence of cloud computing, Big Data and the Internet of Things will require data centers in many places outside the traditional "Big Six" markets (Northern Virginia, New York/New Jersey, Chicago, Dallas, Silicon Valley and Los Angeles). "We're seeing success in the Tier 2 markets," said Kevin Bostick of 365 Data Centers, which operates in markets like Buffalo, Nashville and Pittsburgh. "We feel very confident with our ability to grow in these markets, especially given what we've seen over the past six months." Commercial real estate brokers confirm the trend, citing strong interest in the Pacific Northwest (especially Portland).

Fullstack Launches Coding School For Women

Sat, 17/10/2015 - 6:26am
An anonymous reader writes: Fullstack is tackling technology's diversity problem in its latest venture. The coding schooling has announced a new coding school dedicated to women. Named after computer science pioneer Grace Hopper, the Grace Hopper academy aims to provide women with high-quality coding education, and won't ask for tuition until the student finds a job post-graduation. "Technology has become intrinsic in our daily routines, regardless of gender, but the tech industry remains exceedingly male-dominated," said David Yang, cofounder of Fullstack Academy. "We have always been inspired by innovation and it seems peculiar that an industry revolutionized by a pioneer like Grace Hopper would remain so divided along gender lines."

NBC News Reports US Will Require Registration For Consumer Drones

Sat, 17/10/2015 - 3:28am
Gizmodo and Engadget are both reporting (and both pointing to a report at NBC News) that the Department of Transportation is expected to announce Monday a plan to regulate drone use in the U.S., based on fears of danger to aviation. From the relied-on report at NBC News: The federal government will announce a new plan requiring anyone buying a drone to register the device with the U.S. Department of Transportation, NBC news has learned. ... Under the plan, the government would work with the drone industry to set up a structure for registering the drones, and the regulations could be in place by Christmas. That sounds like an impossible task, if it's to take in all remote-controlled flying devices that might be described as drones. About this time last year, Chris Anderson (ex-Wired editor, and now head of 3D Robotics) estimated that about half a million drones had already been sold in the U.S., and that sounds like an undercount even for then, given the many cheap-and-cheerful options. From suppliers like Banggood, tiny quadcopters can now be had for less than $20, though it's hard to think of them as a danger to aviation.

Jefferson-Designed Chemistry Lab Discovered In UVA Rotunda

Sat, 17/10/2015 - 12:33am
schwit1 writes: An ongoing two-year renovation of the University of Virginia's Rotunda has revealed a chemical lab designed by Thomas Jefferson that dates from the 19th century. Workers uncovered the early science classroom behind a wall on Monday, according to the university. The room was sealed in one of the lower-floor walls of the iconic Rotunda in the mid-1840s and protected from a fire in 1895 that destroyed much of the building's interior. The chemical hearth inside was originally built as a semi-circular niche in the Rotunda, with two fireboxes that provided heat. Brick tunnels underneath the building led fresh air to fireboxes and workstations, while ducts carried away the fumes and smoke. Students at the time worked at five workstations cut into stone countertops.
