Comment The true breakthrough is the anti-mater confinment (Score 1) 456

by Petrut Malaescu (#55442515) Attached to: CERN Scientists Conclude that the Universe Should Not Exist
On a cursory analysis of the article I came across the following line: "Usually the antimatter lifetime is limited by imperfections in the traps – little instabilities allow the antimatter to leak through.But by using a combination of two traps, the BASE team made the most perfect antimatter chamber ever – holding the antiprotons for 405 days. " This is why this type of work is useful to society right now: in order to answer the fundamental questions of the Universe, with precision, it develops new technologies that can be applied to a number of other fields.

Submission + - 72% Of 'Anonymous' Browsing History Can Be Attached To The Real User

An anonymous reader writes: Researchers at Stanford and Princeton have succeeded in identifying 70% of web users by comparing their web-browsing history to publicly available information on social networks.The study De-anonymizing Web Browsing Data with Social Networks [PDF] found that it was possible to reattach identities to 374 sets of apparently anonymous browsing histories simply by following the connections between links shared on Twitter feeds and the likelihood that a user would favour personal recommendations over abstract web browsing.

Submission + - TeraHertz Transmitter Can Push 100Gbps+ Wireless Speeds via a Single Channel

Mark.JUK writes: A team of Japanese scientists working jointly for Hiroshima University and Panasonic have managed to develop a TeraHertz (THz) transmitter that is capable of transmitting digital data at a rate of 105Gbps (Gigabits per second) over a single channel using the frequency range from 290GHz to 315GHz. Previously it was only possible to achieve such speeds by harnessing multiple channels at the same time.

Prof. Minoru Fujishima, Hiroshima University, said: “This year, we developed a transmitter with 10 times higher transmission power than the previous version’s. This made the per-channel data rate above 100 Gbit/s at 300 GHz possible. We usually talk about wireless data rates in megabits per second or gigabits per second. But we are now approaching terabits per second using a plain simple single communication channel."

The team envisages a future where such technology could power Satellite and Mobile communications, although this is still a distant dream as many such technologies struggle to send their signals more than a few metres. Boosting the power can overcome some of the problems, but it also makes related hardware very difficult to convert into a portable form.

Submission + - Haking a Mercedes to autonomous car with a soda can

Petrut Malaescu writes: Last year Mercedes introduced an intelligent Lane Assist system to it's S-class which is cataloged as a Level 1 "Function-specific Automation" aka "hands and feet always on the controls", but a clever(?) driver discovered that all it takes to turn his car up a notch, is a soda can that bypasses the steering wheel sensor which detects the drivers hands. The trick was picked up by Road & Track magazine and I agree that it's not a good idea to try this on a busy highway.

Submission + - Judge: US Search Warrants Apply To Overseas Computers (itworld.com)

jfruh writes: Investigators in a criminal case want to see some emails stored on Microsoft's servers in Ireland. Microsoft has resisted, on the grounds that U.S. law enforcement doesn't have jurisdiction there, but a New York judge ruled against them, responding to prosecutors' worries that web service providers could just move information around the world to avoid investigation. The case will be appealed.
