+ - Short circuit in LHC could delay restart by weeks->

Submitted by hypnosec
hypnosec (2231454) writes "On March 21 CERN detected an intermittent short circuit to ground in one of the LHC's magnet circuits that could delay the restart by anywhere between a few days to several weeks. CERN revealed that the short circuit has affected one of LHC's powerful electromagnets thereby delaying preparations in sector 4-5 of the machine. The European research organisation confirmed that seven of the machine’s eight sectors have successfully been commissioned to 6.5 TeV per beam, but it won't be circulating beam in the LHC this week. Though the short circuit issue is a well understood one, engineers will take time to resolve it since it is in a cold section of the machine and repair may therefore require warming up and re-cooling after repair."

+ - Australian Company Creates Ultra Fast 3D Printer - One-ups Carbon3D

Submitted by ErnieKey
ErnieKey (3766427) writes "One of the major reasons why 3d printing hasn't really caught on all that well is because it is an incredibly slow process. Just last week a company called Carbon3D unveiled a super fast new 3D printing process that utilizes oxygen and light. Now another company — Gizmo 3D — has unveiled an even faster 3d printing process which is even more reliable than the process presented by Carbon3D. It can print 30mm in height at a 50 micron resolution in just 6 minutes flat."

+ - $1B TSA Behavioral Screening Program Slammed as Ineffective "Junk Science"->

Submitted by schwit1
schwit1 (797399) writes "The Transportation Security Administration (TSA) has been accused of spending a billion dollars on a passenger-screening program that’s based on junk science.

The claim arose in a lawsuit (pdf) filed by the American Civil Liberties Union (ACLU), which has tried unsuccessfully to get the TSA to release documents on its SPOT (Screening Passengers by Observation Techniques) [pdf]) program through the Freedom of Information Act.

SPOT, whose techniques were first used in 2003 and formalized in 2007, uses “highly questionable” screening techniques, according to the ACLU complaint, while being “discriminatory, ineffective, pseudo-scientific, and wasteful of taxpayer money.” TSA has spent at least $1 billion on SPOT.

The Government Accountability Office (GAO) reported in 2010 that “TSA deployed SPOT nationwide before first determining whether there was a scientifically valid basis for using behavior detection and appearance indicators as a means for reliably identifying passengers as potential threats in airports,” according to the ACLU. And in 2013, GAO recommended that the agency spend less money on the program, which uses 3,000 “behavior detection officers” whose jobs is to identify terrorists before they board jetliners."

+ - Full-Duplex Radio Integrated Circuit Could Double Radio Frequency Data Capacity->

Submitted by Zothecula
Zothecula (1870348) writes "Full-duplex radio communication usually involves transmitters and receivers operating at different frequencies. Simultaneous transmission and reception on the same frequency is the Holy Grail for researchers, but has proved difficult to achieve. Those that have been built have proven complex and bulky, but to be commercially useful in the ever-shrinking world of communications technology, miniaturization is key. To this end, engineers at Columbia University (CU) claim to have created a world-first, full-duplex radio transceiver, all on one miniature integrated circuit."

+ - New Zealander Creates the World's Smallest Working Drill, Just 17 x 7.5 x 13mm

Submitted by ErnieKey
ErnieKey (3766427) writes "A man from New Zealand, named Lance Abernethy has created what he believes is the world's smallest working cordless drill. Measuring just 17mm tall, 7.5mm wide, and 13mm long, it holds a 0.5mm twist drill and can drill through soft objects. He created it from scratch using a 3D printer and a hearing aid battery."

+ - Nvidia To Install Computers In Cars To Learn How To Drive->

Submitted by jfruh
jfruh (300774) writes "Nvidia has unveiled the Drive PX, a $10,000 computer that will be installed in cars and gather data about how to react to driving obstacles. "Driving is not about detecting, driving is a learned behavior," said Jen Hsun Huang, CEO of Nvidia. The data collected by Drive PXes will be shared, allowing cars to learn the right and wrong reactions to different situations, essentially figuring out what to do from experience rather than a rigid set of pre-defined situations."

+ - Carbon3D Reveals New 3D Printing Process 100X Faster than Current Technology

Submitted by ErnieKey
ErnieKey (3766427) writes "Carbon3D, a stealth startup based in Redwood City, CA. has just announced a new breakthrough 3D printing technology called Continuous Liquid Interface Production technology (CLIP). The process works by using oxygen as an inhibiting agent as a UV light rapidly cures a photosensitive resin. The company has just emerged from stealth mode and announced that they have raised a staggering $41 million to further develop the process and bring it to market."

+ - University of Illinois' Molecular 3D Printer Can Print Billions of Compounds

Submitted by ErnieKey
ErnieKey (3766427) writes "University of Illinois Researchers have created what may end up being the future of 3D printing. The device, called a Molecular-Machine, basically manufactures on the compound level. Martin Burke, the lead researcher on this project says that they are already able to synthesize over a billion different compounds with the machine, compounds which up until now humans have not been able to synthesize. The impact on the pharmaceutical industry could be staggering."

+ - Huge ocean confirmed underneath solar system's largest moon->

Submitted by sciencehabit
sciencehabit (1205606) writes "The solar system’s largest moon, Ganymede, in orbit around Jupiter, harbors an underground ocean containing more water than all the oceans on Earth, according to new observations by the Hubble Space Telescope. Ganymede now joins Jupiter’s Europa and two moons of Saturn, Titan and Enceladus, as moons with subsurface oceans—and good places to look for life. Ceres, the largest object in the asteroid belt, may also have a subsurface ocean. The Hubble study suggests that the ocean can be no deeper than 330 kilometers below the surface."

+ - Man 3D Prints a Working 5-Speed Transmission for Toyota Engines-> 1

Submitted by ErnieKey
ErnieKey (3766427) writes "A man, named Eric Harrell has reverse engineered a 5-speed transmission for a Toyota 22RE Engine, and 3D printed an entire working replica on his desktop 3D printer. Even though it is made up almost entirely of plastic, he says that it could function as a replacement for the real thing. In all it took about 48 hours of print time, plus many more in order to assemble the device. He has made the files available for anyone to download and print themselves for free."

+ - Unique 3D Printed 2-String Violin May Revolutionize the Music Industry->

Submitted by ErnieKey
ErnieKey (3766427) writes "This April, MONAD Studio will unleash 5 new musical instruments which have been 3D printed. They look unlike anything you have seen before, and when combined together will create a massive musical spectacle that could revolutionize the music industry. Created by Eric Goldemberg of FIU, the installment will be on display at the 3D Print Design Show in NY. There are already many musicians lining up to try out these new instruments."
