Unintentional child injuries, deaths can be prevented, public health researchers say

COLUMBIA, Mo. – Patricia Schnitzer, associate professor in the MU Sinclair School of Nursing, says that most unintentional child injury deaths of young children result from inadequate supervision or failure to protect children from harm. Although injuries to children may be unintentional, they can be prevented and should not be considered accidents.

Baker Institute researchers conclude Mexico could become oil importer by 2020 without new investment

Without sufficient investments in upstream oil field activities utilizing new and advanced technologies, Mexico faces the prospect of becoming a net oil importer in 10 years, according to new research by Rice University's James A. Baker III Institute for Public Policy and Oxford University. The stakes of the current political stalemate over oil are quite high, the study concluded.

Digging in dirt, Arbor Day planting, may help build citizenship: UMD study

COLLEGE PARK, Md. - Digging in the ground to plant trees may be an excellent gateway to further involvement in politics and civic affairs, concludes a new University of Maryland study, based on work with New York City environmental volunteers.

"The more a person is involved in environmental stewardship, the more s/he engages with other types of civic and political activities," says the report, "Digging Together", which the researchers released to coincide with Arbor Day.

Clinical trial recommends new antibiotic for treating typhoid in low income countries

A large clinical trial comparing treatments for typhoid has recommended the use of gatifloxacin, a new generation and affordable antibiotic. The results of the trial in Kathmandu, Nepal, funded by the Wellcome Trust and the Li Ka Shing Foundation, are published today in the Lancet Infectious Diseases.

Taking safety personally

A year after the BP explosion and oil spill, those trying to find someone to blame are misguided, says psychological scientist E. Scott Geller, Alumni Distinguished professor at Virginia Tech, and author of a new paper published in Current Directions in Psychological Science, a journal of the Association for Psychological Science. Geller has spent much of his 42-year career developing interventions to keep people safe, particularly helping companies develop a culture that promotes occupational safety.

Crash sensor boosts safety in warehouses

Laser printing speeds parts on demand to manufacturers

Pull into the auto repair shop with a smashed bumper, and there's no wait while they order a replacement. Instead, the technician downloads specifications from the manufacturer's database. You both watch as a laser beam probing a container of liquid plastic material almost magically builds a new bumper inch by inch.

Good eggs: NIST nanomagnets offer food for thought about computer memories

Magnetics researchers at the National Institute of Standards and Technology (NIST) colored lots of eggs recently. Bunnies and children might find the eggs a bit small—in fact, too small to see without a microscope. But these "eggcentric" nanomagnets have another practical use, suggesting strategies for making future low-power computer memories.

Long struggle for appropriately processed manufacturer data leads to a new assessment of memantine

After the manufacturer of the Alzheimer's drug memantine submitted a supplementary analysis of study data, the German Institute for Quality and Efficiency in Health Care (IQWiG) sees proof of a benefit of the drug for cognitive function, as well as indications of a benefit for activities of daily living, at least for a treatment period of 6 months. This changes the conclusions of the first IQWiG benefit assessment of 2009. IQWiG had repeatedly called upon the manufacturer Merz to provide a renewed analysis of study data appropriate to the research question.

Caterpillars inspire new movements in soft robots

Researchers have been examining the diverse behaviours of caterpillars to find solutions for the new generation of search and rescue soft robots.

Despite their extreme flexibility and adaptability, current soft-bodied robots are often limited by their slow speed, leading the researchers to turn to terrestrial soft-bodied animals for inspiration.

New 'nanobead' approach could revolutionize sensor technology

CORVALLIS, Ore. – Researchers at Oregon State University have found a way to use magnetic "nanobeads" to help detect chemical and biological agents, with possible applications in everything from bioterrorism to medical diagnostics, environmental monitoring or even water and food safety.

When fully developed as a hand-held, portable sensor, like something you might see in a science fiction movie, it will provide a whole diagnostic laboratory on a single chip.

The research could revolutionize the size, speed and accuracy of chemical detection systems around the world.

New sensor glove may help stroke patients recover mobility

People who have strokes are often left with moderate to severe physical impairments. Now, thanks to a glove developed at McGill, stroke patients may be able to recover hand motion by playing video games. The Biomedical Sensor Glove was developed by four final-year McGill Mechanical Engineering undergrads under the supervision of Professor Rosaire Mongrain. It is designed to allow patients to exercise in their own homes with minimal supervision, while at the same time permitting doctors to monitor their progress from a distance, thus cutting down on hospital visits and costs.

Green UV sterilization, MEGa-rays for nuclear detection, and cloaking 3-D objects

WASHINGTON, April 26—The world's foremost researchers in laser science, optoelectronics and quantum optics will present their findings at the Conference on Lasers and Electro-Optics (CLEO: 2011), May 1 – 6 at the Baltimore Convention Center. The more than 1,700 presentations at the conference will cover areas from energy and biophotonics to ultrafast lasers and quantum communication. Below is a sampling of the premiere research that will be presented next week at CLEO: 2011 (www.cleoconference.org).

Catastrophic amphibian declines have multiple causes, no simple solution

CORVALLIS, Ore. – Amphibian declines around the world have forced many species to the brink of extinction, are much more complex than realized and have multiple causes that are still not fully understood, researchers conclude in a new report.

The search for a single causative factor is often missing the larger picture, they said, and approaches to address the crisis may fail if they don't consider the totality of causes – or could even make things worse.

Conducting ferroelectrics may be key to new electronic memory

OAK RIDGE, Tenn., April 25, 2011 - Novel properties of ferroelectric materials discovered at the Department of Energy's Oak Ridge National Laboratory are moving scientists one step closer to realizing a new paradigm of electronic memory storage.

A new study led by ORNL's Peter Maksymovych and published in the American Chemical Society's Nano Letters revealed that contrary to previous assumptions, domain walls in ferroelectric materials act as dynamic conductors instead of static ones.
