Much to the chagrin of parents who think their kids should spend less time playing video games and more time studying, time spent playing action video games can actually make dyslexic children read better. In fact, 12 hours of video game play did more for reading skills than is normally achieved with a year of spontaneous reading development or demanding traditional reading treatments.

Improving housing can improve health, particularly when interventions are targeted at those in the poorest health, according to a systematic review published in The Cochrane Library. The authors say their review underscores the importance of targeting those most in need when devising programmes for housing improvement.
DETROIT – A team of researchers led by Shawn P. McElmurry, Ph.D., P.E., assistant professor of civil and environmental engineering in Wayne State University's College of Engineering, has confirmed that seasonal fluctuations in blood lead levels found in children in urban areas throughout the United States and elsewhere in the northern hemisphere are the result of resuspended dust contaminated with lead.
Yttria stabilized zirconia, also known as YSZ, is a material of great interest because of its relatively high oxygen-ion based conductivity. In particular, it finds applications in electrochemical devices, such as solid oxide fuel cells and oxygen sensors. In a study published in EPJ B, Kia Ngai, from the University of Pisa in Italy, and colleagues from the Complutense University in Madrid, Spain, devised a model of the oxygen-ion dynamics that contribute to the conductivity of YSZ.
Millions of tons of food are thrown away each year because the 'best before' date has passed. But this date is always a cautious estimate, which means a lot of still-edible food is thrown away. Wouldn't it be handy if the packaging could 'test' whether the contents are still safe to eat? Researchers at Eindhoven University of Technology, Universitá di Catania, CEA-Liten and STMicroelectronics have invented a circuit that makes this possible: a plastic analog–digital converter. This development brings plastic sensor circuits costing less than one euro cent within reach.
PITTSBURGH—Football fans have become accustomed to viewing televised games from a dozen or more camera angles, but researchers at Carnegie Mellon University and the University of Electro-Communications (UEC) in Tokyo suggest another possible camera position: inside the ball itself.
Amid efforts to expand production of biofuels, scientists are reporting new estimates that downgrade the amount of additional land available for growing fuel crops by almost 80 percent. Their report appears in the ACS journal Environmental Science & Technology.
The results are consistent with previous studies from Finland and Sweden and indicate that the association is not confined to Scandinavian populations. However, the authors stress that the risk may still be overestimated, and they call for longer term monitoring of the cohort of children and adolescents exposed to Pandemrix to evaluate the exact level of risk.
People think of wind as an energy source with few limits, offering an unending power source with distinct capacity advantages over sources that deplete, such as fossil fuel.
Yet, new research in mesoscale atmospheric modeling by UNC Charlotte's Amanda S. Adams and Harvard University's David W. Keith, published Monday in the journal Environmental Research Letters, suggests that the power capacity of large-scale wind farms may have been significantly overestimated.
Washington, DC (26 February 2013)—Across-the-board cuts to US R&D programs could have a devastating impact on efforts to develop new drugs for tuberculosis (TB) and HIV/AIDS, the world's first malaria vaccine, and other vital global health products in development, according to a new report from a coalition of nonprofit groups focused on advancing innovation to save lives.
Northwestern University's Yonggang Huang and the University of Illinois' John A. Rogers are the first to demonstrate a stretchable lithium-ion battery -- a flexible device capable of powering their innovative stretchable electronics.
No longer needing to be connected by a cord to an electrical outlet, the stretchable electronic devices now could be used anywhere, including inside the human body. The implantable electronics could monitor anything from brain waves to heart activity, succeeding where flat, rigid batteries would fail.
PITTSBURGH—Recent research offers a new spin on using nanoscale semiconductor structures to build faster computers and electronics. Literally.
University of Pittsburgh and Delft University of Technology researchers reveal in the Feb. 17 online issue of Nature Nanotechnology a new method that better preserves the units necessary to power lightning-fast electronics, known as qubits (pronounced CUE-bits). Hole spins, rather than electron spins, can keep quantum bits in the same physical state up to 10 times longer than before, the report finds.
It's no secret that China is faced with some of the world's worst pollution. Until now, however, information on the magnitude, scope and impacts of a major contributor to that pollution – human-caused nitrogen emissions – was lacking.
EAST LANSING, Mich. — Fat worms confirm that researchers from Michigan State University have successfully engineered a plant with oily leaves -- a feat that could enhance biofuel production as well as lead to improved animal feeds.
The results, published in the current issue of The Plant Cell, the journal of the American Society of Plant Biologists, show that researchers could use an algae gene involved in oil production to engineer a plant that stores lipids or vegetable oil in its leaves – an uncommon occurrence for most plants.
For decades, archaeologists have struggled with understanding the emergence of a distinct South American civilization during the Late Archaic period (3000-1800 B.C.) in Peru. One of the persistent questions has been the role of agriculture and particularly corn (maize) in the evolution of complex, centralized societies. Up until now, the prevailing theory was that marine resources, not agriculture and corn, provided the economic engine behind the development of civilization in the Andean region of Peru.
