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.
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.
A new mathematical model integrates environmental and molecular sequence information to better explain how microbial networks drive nutrient and energy cycling in marine ecosystems.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Over the years, techniques and equipment for digital mapping have revolutionized the way geoscience field studies are performed. Now a unique new software for virtual model interpretation and visualization is revealed by researchers.
Human babies and even animals have a basic number sense that many believe evolves from seeing the world and trying to quantify all the sights. But vision has nothing to do with it -- neuroscientists have found that the brain network behind numerical reasoning is identical in blind and sighted people.
