Preterm children do not suffer from dyscalculia more often than healthy full-term children, experts say, contrary to previous studies. Unlike most other studies, the researchers took the children’s IQ into consideration.
Scientists have new clues this week about one of the baffling electronic properties of the iron-based high-temperature superconductor barium iron nickel arsenide. Scientists have the first evidence, based on sophisticated neutron measurements, of a link between magnetic properties and the material's tendency, at sufficiently low temperatures, to become a better conductor of electricity in some directions than in others.
Researchers have shown that BMP and WNT proteins are the so-called 'Turing molecules' for creating embryonic fingers. Findings explain why polydactyly -- the development of extra fingers or toes -- is relatively common in humans, affecting up to one in 500 births, and confirms a fundamental theory first proposed by the founding father of computer science, Alan Turing, back in 1952.
A new study could greatly improve current methods of localizing birdsong data. The study demonstrates the validity of using approximate maximum likelihood (AML) algorithms to determine the direction of arrival (DOA) of birdsong sources.
Researchers were able to simulate human facial expressions in virtual characters and use them in order to create better environments within a virtual communication.
Scientists analyzed the causes of risk tolerance and found that loss aversion, or the fear of losing money, is the primary factor that explains investors' risk tolerance.
What paths do quantum particles, such as atoms or photons, follow through quantum state space? Scientists have used an "artificial atom" to continuously and repeatedly record the paths through quantum state space. From the cobweb of a million paths, a most likely path between two quantum states emerged, much as social trails emerge as people round off corners or cut across lawns between buildings.
Companies who make their money in the 'sin' industries such as the tobacco, alcohol and gaming industries typically receive less attention from institutional investors and financial analysts. But new research shows social norms and attitudes towards these types of businesses are subject to compromise when their share price looks to be on the rise.
Spintronics is a new field of electronics, using electron spin rather than motion. This technology requires insulating components that can control this quantum property. Scientists have shown experimentally that a novel material shows all the required properties.
Between three and six percent of schoolchildren suffer from an arithmetic-related learning disability. Researchers now show that these children are also more likely to exhibit deficits in reading and spelling than had been previously suspected.
An academic led a lab-based research, involving 433 viewers of ages from 4 to 82 years, in which participants were asked to watch Toy Story in either 2-D or 3-D (S3D) and report on their viewing experience. The objective of the study was to investigate visual discomfort in relation to 3-D display technologies, as well as to determine the impact of people’s preconceptions on their experience of 3D TV. It’s no secret that the format hasn’t taken off in the way many had anticipated.
Contrary to widespread media reports, the collapse of several financial firms during the 2008 economic crisis was not triggered by unsettled stock trades, according to new research.
Researchers are developing vision-correcting displays that can compensate for a viewer's visual impairments to create sharp images without the need for glasses or contact lenses. The technology could potentially help those who currently need corrective lenses to use their smartphones, tablets and computers, and could one day aid people with more complex visual problems.
A new study investigates the effects of small but finite inertia on the propulsion of micro and nano-scale swimming machines. Scale plays a major role in locomotion. Swimming microorganisms, such as bacteria and spermatozoa, are subjected to relatively small inertial forces compared to the viscous forces exerted by the surrounding fluid. Such low-level inertia makes self-propulsion a major challenge. Now, scientists have found that the direction of propulsion made possible by such inertia is opposite to that induced by a viscoelastic fluid.
A new study shows consumer savings from the Kill Switch legislation exceed initial projections and now points to well over $3 billion. This savings to consumers comes at the expense of insurance and wireless industry profits.
Giving parents access to a dedicated website on the measles, mumps and rubella vaccine is the most cost-effective way to increase uptake, say experts. "A website is a simple solution but one that could make a real difference to vaccination uptake. This is a much more convenient way for parents to get information they need about the safety of the MMR vaccine for their children," one expert said.
It seems common practice: After a long day at work, most people sometimes just want to turn on the TV or play a video or computer game to calm down and relax. However, in a new study researchers found that people who were highly stressed after work did not feel relaxed or recovered when they watched TV or played computer or video games. Instead, they tended to show increased levels of guilt and feelings of failure.
An electronic screening tool that starts with a single question to assess the frequency of substance misuse appears to be an easy way to screen teenagers who visited a physician for routine medical care.
While the mobile health apps market offers tremendous potential, several health law experts say that more oversight is needed by the US Food and Drug Administration to ensure consumer confidence and safety. Out of 100,000 mHealth apps on the market, only about 100 have been cleared by the FDA, which opponents see as a deterrent to innovation and profit. But it doesn't have to be.
A team of researchers has developed a method to automatically identify topics that people search for on Google before subsequent stock market falls.
