Effects of Arizona's immigration law on Latino youth and families

In 2010, Arizona passed an immigration law (S.B. 1070, the Support Our Law Enforcement and Safe Neighborhoods Act) that gave state police unprecedented power to detain individuals unable to prove their U.S. citizenship when asked. At a symposium during the Biennial Meeting of the Society for Research in Child Development (SRCD), researchers will examine the effect of the law on the health and well-being of Latino youth and families.

Prototype generators emit much less carbon monoxide, NIST finds

Portable electric generators retrofitted with off-the-shelf hardware by the University of Alabama (UA) emitted significantly lower levels of carbon monoxide (CO) exhaust, according to the results* of tests conducted by the National Institute of Standards and Technology (NIST) for the U.S. Consumer Product Safety Commission (CPSC).

Compared with standard portable generators, CO emissions from the prototype machines were reduced by 90 percent or more, depending on the specific hardware used and operating conditions.

Super-nanotubes: 'Remarkable' spray-on coating combines carbon nanotubes with ceramic

Researchers from the National Institute of Standards and Technology (NIST) and Kansas State University have demonstrated a spray-on mixture of carbon nanotubes and ceramic that has unprecedented ability to resist damage while absorbing laser light.*

Children and teens with autism more likely to become preoccupied with video games

COLUMBIA, Mo. – Children and teens with autism spectrum disorder (ASD) use screen-based media, such as television and video games, more often than their typically developing peers and are more likely to develop problematic video game habits, a University of Missouri researcher found.

Navy develops high impact, high integrity polymer for air, sea, and domestic applications

WASHINGTON--U.S. Naval Research Laboratory Chemistry Division scientists have developed a second generation, cost-effective polyetheretherketone (PEEK)-like phthalonitrile-resin demonstrating superior high temperature and flammability properties for use in numerous marine, aerospace and domestic applications.

Security holes in smartphone apps

Popular texting, messaging and microblog apps developed for the Android smartphone have security flaws that could expose private information or allow forged fraudulent messages to be posted, according to researchers at the University of California, Davis.

Zhendong Su, professor of computer science, said that his team has notified the app developers of the problems, although it has not yet had a response.

How smart are your clothes?

Montreal, April 16, 2013 – From corsets to caftans, we have seen dramatic changes in popular style over the past 100 years. New research from Concordia University now brings the future of fashion into focus by taking a closer look at the next quantum leap in textile design: computerized fabrics that change their colour and their shape in response to movement.

Common pregnancy conditions risk future diabetes

Two common conditions in pregnancy may be risk factors for future diabetes according to a Canadian study of over one million women published in this week's PLOS Medicine.

The researchers, led by Denice Feig from the University of Toronto, Canada, found that pre-eclampsia (a condition in which affected pregnant women have high blood pressure, fluid retention, and protein in their urine), and gestational hypertension (high blood pressure associated with pregnancy) could double the chance of being diagnosed with diabetes many years after pregnancy.

Small in size, big on power: New microbatteries the most powerful yet

CHAMPAIGN, Ill. — Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery – and then recharge the phone in the blink of an eye.

Developed by researchers at the University of Illinois at Urbana-Champaign, the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics.

NREL and partners demonstrate quantum dots that assemble themselves

Scientists from the U.S. Department of Energy's National Renewable Energy Laboratory and other labs have demonstrated a process whereby quantum dots can self-assemble at optimal locations in nanowires, a breakthrough that could improve solar cells, quantum computing, and lighting devices.

A paper on the new technology, "Self-assembled Quantum Dots in a Nanowire System for Quantum Photonics," appears in the current issue of the scientific journal Nature Materials.

NREL survey shows dramatic improvement in B100 biodiesel quality

The latest national survey of 100% biodiesel (B100) "blend stock" samples by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) found that 95% of the samples from 2011-12 met ASTM International fuel quality specifications. The ASTM standards serve as guidelines for industry and are designed to ensure quality at the pump for consumers – along with reliable operation of the nation's vehicles powered by biodiesel blends.

NREL and Stanford team up on peel-and-stick solar cells

It may be possible soon to charge cell phones, change the tint on windows, or power small toys with peel-and-stick versions of solar cells, thanks to a partnership between Stanford University and the U.S. Department of Energy's National Renewable Energy Laboratory (NREL).

A scientific paper, "Peel and Stick: Fabricating Thin Film Solar Cells on Universal Substrates," appears in the online version of Scientific Reports, a subsidiary of the British scientific journal Nature.

Building a better capacitor with custom nanorods

A new process for growing forests of manganese dioxide nanorods may lead to the next generation of high-performance capacitors.

Better coordination necessary to reduce hospital readmission rates

Achieving widespread reductions in preventable hospital readmissions among Medicare beneficiaries may take longer than many health care professionals originally anticipated, according to researchers at Penn State, the Weill Cornell Medical College and the University of Pennsylvania.
