Mysterious polio-like illness found in 5 California children

PHILADELPHIA – Researchers have identified a polio-like syndrome in a cluster of children from California over a one-year period, according to a case report released today that will be presented at the American Academy of Neurology's 66th Annual Meeting in Philadelphia, April 26 to May 3, 2014.

New, inexpensive production materials boost promise of hydrogen fuel

MADISON, Wis. — Generating electricity is not the only way to turn sunlight into energy we can use on demand. The sun can also drive reactions to create chemical fuels, such as hydrogen, that can in turn power cars, trucks and trains.

The trouble with solar fuel production is the cost of producing the sun-capturing semiconductors and the catalysts to generate fuel. The most efficient materials are far too expensive to produce fuel at a price that can compete with gasoline.

Air Force aircraft returned from Vietnam identified as postwar source of Agent Orange contamination

Amsterdam, February 21, 2014 – From 1971-1982 Air Force reservists, who flew in about 34 dioxin-contaminated aircraft used to spray Agent Orange and returned to the US following discontinuation of the herbicide spraying operations in the Vietnam War, were exposed greater levels of dioxin than previously acknowledged, according to a study published today in Environmental Research.

Nanoscale pillars could radically improve conversion of heat to electricity

University of Colorado Boulder scientists have found a creative way to radically improve thermoelectric materials, a finding that could one day lead to the development of improved solar panels, more energy-efficient cooling equipment, and even the creation of new devices that could turn the vast amounts of heat wasted at power plants into more electricity.

UT Dallas-led team makes powerful muscles from fishing line and sewing thread

An international team led by The University of Texas at Dallas has discovered that ordinary fishing line and sewing thread can be cheaply converted to powerful artificial muscles.

The new muscles can lift a hundred times more weight and generate a hundred times higher mechanical power than the same length and weight of human muscle. Per weight, they can generate 7.1 horsepower per kilogram, about the same mechanical power as a jet engine.

Scientists create powerful artificial muscle with fishing line

Researchers are using fibres from fishing line and sewing thread to create inexpensive artificial muscles that could be used in medical devices, humanoid robots, prosthetic limbs, or woven into fabrics.

In a study published today in Science, international researchers, including University of British Columbia Electrical and Computer Engineering professor John Madden and PhD candidate Seyed Mohammad Mirvakili, detail how they created inexpensive artificial muscles that generate far more force and power than human or animal muscles of the same size.

Smaller meals more times per day may curb obesity in cats

URBANA, Ill. – Just as with people, feline obesity is most often linked to excessive food intake or not enough physical activity. Attempts to cut back on calories alone often result in failed weight loss or weight regain in both people and their pets.

So how do you encourage your cat to get more exercise?

Researchers from the University of Illinois interested in finding a method to maintain healthy body weight in cats, looked at a previously suggested claim that increased meal frequency could help to increase overall physical activity.

Study examines correctional officer stress

HUNTSVILLE, TX (2/20/14) -- Conflicts between work and family life were the most significant issues that affect work stress and job satisfaction among correctional officers, a new study by the Correctional Management Institute of Texas at Sam Houston State University found.

Spotlighting black chemists and chemical engineers (video)

WASHINGTON, Feb. 20, 2014 — Their research may lead to a new generation of renewable fuels, medical devices and safer home products. The American Chemical Society (ACS) is continuing its celebration of Black History Month with a new video featuring several African-American chemists and chemical engineers doing cutting edge research today. The video is available at http://youtu.be/v0PmKbJNAQI.

From a distance: New technique for repair work

This news release is available in German.

Numerous German companies are operating globally these days: They develop products domestically, but production is done in other countries like China, Brazil or the Czech Republic. If maintenance or repair work is needed, the engineers who had designed the complex production plants frequently have to travel from Germany.

A new laser for a faster Internet

A new laser developed by a research group at Caltech holds the potential to increase by orders of magnitude the rate of data transmission in the optical-fiber network—the backbone of the Internet.

New research blows away claims that aging wind farms are a bad investment

The UK has a target of generating 15 per cent of the nation's energy from renewable resources such as wind farms by 2020. There are currently 4,246 individual wind turbines in the UK across 531 wind farms, generating 7.5 per cent of the nation's electricity.

ORNL microscopy system delivers real-time view of battery electrochemistry

OAK RIDGE, Tenn., Feb. 19, 2014 -- Using a new microscopy method, researchers at the Department of Energy's Oak Ridge National Laboratory can image and measure electrochemical processes in batteries in real time and at nanoscale resolution.

Scientists at ORNL used a miniature electrochemical liquid cell that is placed in a transmission electron microscope to study an enigmatic phenomenon in lithium-ion batteries called the solid electrolyte interphase, or SEI, as described in a study published in Chemical Communications.

A step closer to a photonic future

WASHINGTON, Feb. 19–The future of computing may lie not in electrons, but in photons – that is, in microprocessors that use light instead of electrical signals. But these so-called photonic devices are typically built using customized methods that make them difficult and expensive to manufacture.

Making nanoelectronics last longer for medical devices, 'cyborgs'

The debut of cyborgs who are part human and part machine may be a long way off, but researchers say they now may be getting closer. In a study published in ACS' journal Nano Letters, they report development of a coating that makes nanoelectronics much more stable in conditions mimicking those in the human body. The advance could also aid in the development of very small implanted medical devices for monitoring health and disease.
