This New Discovery Could Put Quantum Computers Within Closer Reach (Mar 22, 2016)
One of the obstacles that has kept quantum computers on the distant horizon is the fact that quantum bits -- the building blocks with which they're made -- are prone to magnetic disturbances. Such "noise" can interfere with the work qubits do, but scientists announced a new discovery that could help solve the problem. Specifically, by tapping the same principle that allows atomic clocks to stay accurate, researchers at Florida State University’s National High Magnetic Field Laboratory have fou...

Computer-Assisted Approaches as Decision Support Systems Serving to Combat the Zika Virus (Mar 22, 2016)
Global climate change, international travel and ineffective vector control programs are aiding the emergence of infectious diseases globally. The currently expanding Zika virus epidemic is one such problem. The rapid expansion of this disease to epidemic proportions in South America in 2015-16 has led the World Health Organization to declare ZIKV a public health emergency. No drug is known to treat ZIKV infection; neither do we have any vaccine which can prevent the spread of the virus. While sc...

The World's First Solar Airport No Longer Pays for Electricity (Mar 21, 2016)
Fed up with their hefty electricity bill, managers at Cochin International Airport in southern India took matters into their own hands. Three years ago, they began adding solar panels -- first on the roof of the arrivals terminal, then on and around an aircraft hangar. The success of those initial efforts led to a much bigger endeavor. Last year, the airport commissioned the German company Bosch to build a vast 45-acre solar plant on unused land near the international cargo terminal. The plant c...

Discovery Could Herald New Particle (Mar 19, 2016)
First gravitational waves opened a new window on the universe. Now data from the Large Hadron Collider, or LHC, in Switzerland could change the standard model of physics. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences analyzed LHC information from 2011 and 2012 and noticed an anomaly that wasn't predicted by the standard model, the institute said in a press release.



Dark Matter Satellites Trigger Massive Birth of Stars (Mar 18, 2016)
One of the main predictions of the current model of the creation of structures in the universe, known at the Lambda Cold Dark Mattermodel, is that galaxies are embedded in very extended and massive halos of dark matter that are surrounded by many thousands of smaller sub-halos also made from dark matter. Around large galaxies, such as the Milky Way, these dark matter sub-halos are large enough to host enough gas and dust to form small galaxies on their own, and some of these galactic companions,...

Show, Don't Tell: How Video is Swamping the Internet (Mar 17, 2016)
Asked what inspired him to write the cult 1979 hit single Video Killed the Radio Star, songwriter Trevor Horn said it came from the idea that "video technology was on the verge of changing everything". More than 35 years later, it's digital video - particularly on mobile - that is changing everything again. Video will account for 80% of all internet traffic by 2019, up from 64% in 2014, says technology giant Cisco. Facebook founder Mark Zuckerberg says that 90% of the social network's content wi...

Making Sense of HPC in the Age of Democratization (Mar 15, 2016)
These are exciting times for HPC. High-performance computing and its cousin high-productivity computing are expanding such that the previous definitions of HPC as a moving performance target or as the purview of modeling and simulation are breaking down. The democratization of HPC has spurred a lot of focus on the impact that HPC-hatched technologies are having on business computing, but HPC “proper” is also in the midst of a transformation.

Sharpening a New Fork for HPC Cluster Tuning (Mar 14, 2016)
There is a long-running joke in high performance computing that for any question that can be asked, the answer is probably going to be “it depends.” This maxim persists because there is an incredible amount of diversity of hardware, software, middleware, applications, and other factors that make coming up with a universally true statement about any tuning or optimization impossible. This same sentiment might also be applied in warehouse scale datacenters, although the number of parameters an...

This Electric Bicycle Can Go Up to 40 MPH (Mar 14, 2016)
I've never been the type of guy to ride a motorcycle. I'm more of the play-it-safe type. Plus, I don't own a black leather jacket. Now, I'm shedding my good-boy image for an electric bike called Bolt. It looks, feels and acts like a motorcycle with one big difference: It's not. The Bolt has pedals and can limit its speed to 20 miles per hour, so most states consider it an "electric bicycle." That means you don't need a license, registration or insurance, plus you don't need to fill it up with an...

Amputee Feels Texture With a Bionic Fingertip (Mar 13, 2016)
An amputee was able to feel smoothness and roughness in real-time with an artificial fingertip that was surgically connected to nerves in his upper arm. Moreover, the nerves of non-amputees can also be stimulated to feel roughness, without the need of surgery, meaning that prosthetic touch for amputees can now be developed and safely tested on intact individuals.



Wearable Technology May Soon Make Sign Language Audible (Mar 12, 2016)
Remember that Samsung Turkey video of a whole town learning sign language to surprise a young deaf man from Istanbul? It’s okay to admit that you got a little bit teary-eyed while watching that video. We’ve often been impressed with stories of people learning sign language to communicate with a person in their community. But a new technology developed by researchers at Texas A&M are now giving the deaf a voice. The device uses a system of sensors that recognizes the motion of hand gestures a...
