Biggest beast in big data forest? One field's astonishing growth is 'genomical'

Tue, 07/07/2015 - 19:24
Who's about to become the biggest beast in the big data forest? A group of computing experts have arrived at an answer. It's not You Tube or Twitter, social media sites that gobble up awesome quantities of bandwidth, and it's not astronomy or particle physics. No, the alpha beast in the big data forest is genomics -- a science that didn't exist 15 years ago and just beginning to break out from the field.

Omnidirectional free space wireless charging of multiple wireless devices

Tue, 07/07/2015 - 16:00
Scientists have made great strides in wireless-power transfer development. A new WPT system is capable of charging multiple mobile devices concurrently and with unprecedented freedom in any direction, even while holding the devices in midair or a half meter away from the power source, which is a transmitter.

Smartphones may be detrimental to learning process

Tue, 07/07/2015 - 16:00
A yearlong study of first-time smartphone users has found that users felt smartphones were actually detrimental to their ability to learn. The research reveals the self-rated impact of smartphones among the users.

Policies on children's tech exposure confusing

Tue, 07/07/2015 - 13:33
Guidelines on children's exposure to radio frequency waves from technology are confusing for parents, new research suggests. The review found a wide variety of different protocols and guidelines across 34 countries.

Big PanDA and Titan merge to tackle torrent of LHC's full-energy collision data

Tue, 07/07/2015 - 13:02
With the successful restart of the Large Hadron Collider, now operating at nearly twice its former collision energy, comes an enormous increase in the volume of data physicists must sift through to search for new discoveries. Fortunately, a remarkable data-management tool developed by physicists is evolving to meet the big-data challenge.

New smartphone app warns drinkers if they go over recommended daily/weekly units

Tue, 07/07/2015 - 12:24
A new smartphone app warns drinkers if they go over the recommended maximum daily/weekly units of alcohol, to help them better manage their intake, researchers report.

Could black phosphorus be the next silicon?

Tue, 07/07/2015 - 12:23
Researchers report that when electrons move in a phosphorus transistor, they do so only in two dimensions. The finding suggests that black phosphorus could help engineers surmount one of the big challenges for future electronics: designing energy-efficient transistors.

Crowd computing to improve water filtration

Mon, 07/06/2015 - 16:37
Scientists propose a novel nanotechnology-based strategy to improve water filtration. The project was an experiment in crowdsourced computing -- carried out by over 150,000 volunteers who contributed their own computing power to the research.

Researchers design a new system to make overtaking safer on highways

Mon, 07/06/2015 - 13:00
Researchers have designed EYES, a new system for smartphones and tablets –now in the prototype phase– which aims to make overtaking manoeuvres safer on highways. EYES provides visual help to the driver when he overtakes and it is also useful in monitoring manoeuvres for autonomous vehicles (platooning).

Detecting eye diseases using a Smartphone

Sat, 07/04/2015 - 12:45
Researchers have developed software that detects eye diseases such as diabetic macular edema using a smartphone. The system is aimed at general physicians who could detect the condition and refer the patient to a specialist.

'Ghost': Technology that leaps out of the screen

Fri, 07/03/2015 - 11:27
Exciting new technologies, which allow users to change the shape of displays with their hands, promise to revolutionize the way we interact with smartphones, laptops and computers. Imagine pulling objects and data out of the screen and playing with these in mid-air. Today we live in a world of flat-screen displays we use all day – whether it’s the computer in the office, a smartphone on the train home, the TV or iPad on the couch in the evening. The world we live in is not flat, though; it’s made of hills and valleys, people and objects. Imagine if we could use our fingertips to manipulate the display and drag features out of it into our 3D world.

Why the seahorse's tail is square

Thu, 07/02/2015 - 19:13
Why is the seahorse's tail square? An international team of researchers has found the answer and it could lead to building better robots and medical devices. In a nutshell, a tail made of square, overlapping segments makes for better armor than a cylindrical tail. It's also better at gripping and grasping.

Encryption made easier: Just talk like a parent

Thu, 07/02/2015 - 17:18
A researcher has created an easier email encryption method – one that sounds familiar to parents who try to outsmart their 8-year-old child. The new technique gets rid of the complicated, mathematically generated messages that are typical of encryption software. Instead, the method transforms specific emails into ones that are vague by leaving out key words.

Intrusiveness of old emotional memories can be reduced by computer game play procedure

Thu, 07/02/2015 - 13:49
Unwanted, intrusive visual memories are a core feature of stress- and trauma-related clinical disorders such as posttraumatic stress disorder (PTSD), but they can also crop up in everyday life. New research shows that even once intrusive memories have been laid down, playing a visually-demanding computer game after reactivating the memories may reduce their occurrence over time.
