Programmable ions set the stage for general-purpose quantum computers

Wed, 08/03/2016 - 18:01
Scientists have introduced the first fully programmable and reconfigurable quantum computer module.

Sprinkling of neural dust opens door to electroceuticals

Wed, 08/03/2016 - 18:01
Monitoring electrical signals from muscles and nerves has become easier with a 1x1x3 mm sensor that can be implanted anywhere in the body, powered and read out by ultrasound. With further miniaturization, these sensors could replace brain electrodes wired through the skull to control prosthetics, but also allow real time monitoring of nerve and muscle activity, or oxygen or metabolite levels. It could eventually be used to stimulate muscles or nerves, e.g. to treat epilepsy.

Free chrome plugin visualizes PubMed gene, protein, drug and disease connections

Wed, 08/03/2016 - 16:45
New text-mining tool helps researchers map connections between genes, proteins, drugs, diseases.

Challenging the 'rigidity' for smart soft electronics

Wed, 08/03/2016 - 14:39
A team of researchers has found a way to solve a dilemma and developed a low crystalline conducting polymer that shows high-field effect mobility, according to a new report.

Reach in and touch objects in videos

Wed, 08/03/2016 - 13:52
A new technique called Interactive Dynamic Video (IDV) lets you reach in and 'touch' objects in videos. IDV has many possible uses, from filmmakers producing new kinds of visual effects to architects determining if buildings are structurally sound.

Speaking the language of microstructures

Wed, 08/03/2016 - 11:57
Researchers are developing a common language that can be used by computer software tools to describe materials at their smallest scale, with the ultimate aim of designing faster and better materials for our everyday lives.

'Virtual dental homes' prove safe, effective, shows six-year California study

Tue, 08/02/2016 - 19:13
Teledentistry can safely and effectively deliver dental care to people who lack it, according to a six-year demonstration. Bringing "virtual dental homes" to schools, nursing homes and long-term care facilities can keep people healthy -- reducing school absenteeism, lessening the need for parents to leave work to care for an ailing child, and helping to prevent suffering for millions of people who have no access to a dentist, the study shows.

Low rate of Internet use by seniors for health purposes

Tue, 08/02/2016 - 16:52
Researchers examined trends in seniors' use of digital health technology in the US from 2011-2014.

Computers will be able to assess humans' state of mind

Tue, 08/02/2016 - 14:42
Machines are taking over more and more tasks. Ideally, they should also be capable to support the human in case of poor performance. To intervene appropriately, the machine should understand what is going on with the human. Scientists have developed a diagnostic tool that recognizes user states in real time and communicates them to the machine.

How computer algorithms shape our experience of the real world

Tue, 08/02/2016 - 14:41
The use of algorithms to filter and present information online is increasingly shaping our everyday experience of the real world, a study argues.

Ultrasonic vibrations cause fingers to bounce on touchscreens, reducing the friction

Tue, 08/02/2016 - 14:37
Researchers discover that ultrasonic vibrations reduce friction on flat screens by causing the fingertip to bounce on pockets of trapped air.

People not technology will drive success of autonomous vehicles

Tue, 08/02/2016 - 14:37
As the world moves closer to autonomous and self-driving vehicles, road safety experts are turning from technology to psychology to better understand the road to safer mobility.

Flow diagnostics breakthrough for hydraulic capsule pipeline

Tue, 08/02/2016 - 14:37
Pipelines that carry capsules containing almost any type of freight over long distances have the potential to become an important, cost-effective and environmentally friendly form of transportation. Now, research has led to the development of mathematical models that can ensure new pipeline systems are designed to be as economic and efficient as possible.

Bridging the gap between the quantum and classical worlds

Tue, 08/02/2016 - 14:35
Strong coupling in specific light-matter interactions, previously believed to be a quantum phenomenon, is explained with classical models and experiments.

Crystallization frustration predicts metallic glass formation

Tue, 08/02/2016 - 14:33
Researchers have discovered a way to predict which alloys will form metallic glasses, materials with numerous desirable properties. The research could pave the way for new strong, conductive materials.

Restoring prairie and fighting wildfire with (drone launched) fire(balls)

Mon, 08/01/2016 - 20:50
One ecologist wants to change the way we think about prescribed burns. The professor says he can harness extreme fire to restore grasslands on the Great Plains -- and he has created a small drone that launches ping-pong balls of fire to help him do it safely and cheaply.

How birds soar to great heights

Mon, 08/01/2016 - 20:38
Biologists and physicists have demonstrated with mathematical models how glider pilots might be able to soar more efficiently by adopting the learning strategies that birds use to navigate their way through thermals.

New silicon structures could make better biointerfaces

Mon, 08/01/2016 - 17:12
A team of researchers have engineered silicon particles one-fiftieth the width of a human hair, which could lead to "biointerface" systems designed to make nerve cells fire and heart cells beat.

Real and artificially generated 3-D films are nearly impossible to distinguish

Mon, 08/01/2016 - 17:11
For viewers it seems to be very difficult to tell the difference between real and artificially rendered 3-D films. Psychologists have studied the effects of various technologies and found that it plays virtually no role in the viewer's experience whether a 3-D film was originally produced as such or whether it was later converted from 2-D to 3-D using algorithms as, for example, is the case with new 3-D televisions.

Autism genes identified using new approach

Mon, 08/01/2016 - 15:38
Researchers have developed a machine-learning approach that for the first time analyzes the entire human genome to predict which genes may cause autism spectrum disorder, raising the number of genes that could be linked to the disorder from 65 to 2,500.
