Automated screening for childhood communication disorders

Fri, 09/23/2016 - 13:53
For children with speech and language disorders, early-childhood intervention can make a great difference in their later academic and social success. But many such children -- one study estimates 60 percent -- go undiagnosed until kindergarten or even later.

With great power comes great laser science

Thu, 09/22/2016 - 16:43
Scientists have found a way to compress ultrashort laser pulses, increasing its peak power to half a terawatt – which is equivalent to the output of hundreds of nuclear reactors.

New model could point way to microbiome forecasting in the ocean

Thu, 09/22/2016 - 15:28
A new mathematical model integrates environmental and molecular sequence information to better explain how microbial networks drive nutrient and energy cycling in marine ecosystems.

Applying heat to stay on track

Thu, 09/22/2016 - 13:59
As the density of data stored on a hard drive gets close to multiple terabytes per square centimeter, the precision of the internal components is becoming increasingly significant. A clever electro-thermal actuator and lever system keeps hard drive recording heads on track, report scientists.

Robot doesn't have to behave and look like a human

Thu, 09/22/2016 - 12:53
The R2-D2 robot from Star Wars doesn’t communicate in human language but is, nevertheless, capable of showing its intentions. For human-robot interaction, the robot does not have to be a true ‘humanoid,’ provided that its signals are designed in the right way, say researchers.

Computers learn to spot deadly bacteria

Wed, 09/21/2016 - 20:33
Machine learning can predict strains of bacteria likely to cause food poisoning outbreaks, research has found. The study -- which focused on harmful strains of E. coli bacteria -- could help public health officials to target interventions and reduce risk to human health. The researchers used software that compares genetic information from bacterial samples isolated from both animals and people.

Video gamers outdo scientists in contest to discover protein's shape

Wed, 09/21/2016 - 20:27
Gamers playing the popular online puzzle game Foldit beat scientists, college students and computer algorithms in a contest to see who could identify a particular protein's shape.

The microdoctors in our bodies

Wed, 09/21/2016 - 18:30
Researchers are developing tiny, sophisticated technological and biological machines enabling non-invasive, selective therapies. Their creations include genetically modified cells that can be activated via brain waves, and swarms of microrobots that facilitate highly precise application of drugs.

Next generation of statistical tools to be developed for the big data age

Wed, 09/21/2016 - 15:52
Statisticians are developing new ways to interpret the unprecedented amounts of data being generated continuously all around us. Whether it is smart phones packed full of sensors measuring your health, location and the weather, or connected cars driving past roadside monitors measuring traffic volumes or air quality, or even thousands of sensors on individual oil wells, in the world of the ‘Internet of Things’ and ‘big data’ massive streams of information are now being generated and collected at an unprecedented scale.

Computers: Cache management improved once again

Wed, 09/21/2016 - 14:16
A year ago, researchers unveiled a fundamentally new way of managing memory on computer chips, one that would use circuit space much more efficiently as chips continue to comprise more and more cores, or processing units. In chips with hundreds of cores, the researchers' scheme could free up somewhere between 15 and 25 percent of on-chip memory, enabling much more efficient computation.

Detecting emotions with wireless signals

Wed, 09/21/2016 - 13:39
Researchers have developed "EQ-Radio," a device that can detect a person's emotions using wireless signals. By measuring subtle changes in breathing and heart rhythms, EQ-Radio is 87 percent accurate at detecting if a person is excited, happy, angry or sad -- and can do so without on-body sensors.

Physicists create nano-sized device with huge potential in field of quantum computing

Wed, 09/21/2016 - 12:39
An intricately sculpted device is so tiny it can only be seen under a microscope. But their diamond microdisk could lead to huge advances in computing, telecommunications, and other fields.

Beam me up Scotty! Quantum teleportation of a particle of light six kilometers

Wed, 09/21/2016 - 12:26
What if you could behave like the crew on the Starship Enterprise and teleport yourself home or anywhere else in the world? As a human, you're probably not going to realize this any time soon; if you're a photon, you might want to keep reading.

Virtual reality training improves social skills of individuals on the autism spectrum

Tue, 09/20/2016 - 18:18
Children with autism spectrum disorder, who participated in a virtual reality training program, improved social cognition skills and reported better real-world relationships. Neurocognitive testing showed significant gains in emotional recognition, understanding the perspective of others and the ability to problem solve.

Calls for greater transparency in the release of clinical trial data

Tue, 09/20/2016 - 18:16
Researchers have called for greater transparency in the public release of clinical trial data after a study revealed significant under-reporting of side effects in medical treatments.

Reconfigurable chaos-based microchips offer possible solution to Moore’s Law

Tue, 09/20/2016 - 17:04
Researchers have developed new, nonlinear, chaos-based integrated circuits that enable computer chips to perform multiple functions with fewer transistors. These integrated circuits can be manufactured with "off the shelf" fabrication processes and could lead to novel computer architectures that do more with less circuitry and fewer transistors.

Video games can have lasting impact on learning

Tue, 09/20/2016 - 14:42
A computer-based brain training program helps improve student performance in reading and math — in some cases even more than individualized tutoring, according to a new study.

Acoustic resonator device paves the way for better communication

Tue, 09/20/2016 - 14:34
A high-frequency version of a device known as an acoustic resonator has now been developed that could advance the field of quantum computing and information processing, say scientists.
