Household robots do not protect users' security and privacy, researchers say

People are increasingly using household robots for chores, communication, entertainment and companionship. But safety and privacy risks of information-gathering objects that move around our homes are not yet adequately addressed, according to a new University of Washington study.

It's not a question of evil robots, but of robots that can be misused.

Nanotechnology accelerates cellulosic ethanol development

Dr. James Palmer, associate professor of chemical engineering at Louisiana Tech University, is collaborating with fellow professors Dr. Yuri Lvov, Dr. Dale Snow, and Dr. Hisham Hegab to capitalize on the environmental and financial benefits of "biofuels" by using nanotechnology to further improve the cellulosic ethanol processes.

Immune cell entry into the pancreatic islets key to understanding type 1 diabetes origins

St. Jude Children's Research Hospital investigators have discovered how destructive immune cells gain access to insulin-producing cells and help cause diabetes.

The finding points to possible new strategies to halt or prevent type I diabetes.

Reseachers create nanometric butterfly wings

A team of researchers from the State University of Pennsylvania (USA) and the Universidad Autónoma de Madrid (UAM) have developed a technique to replicate biological structures, such as butterfly wings, on a nano scale. The resulting biomaterial could be used to make optically active structures, such as optical diffusers for solar panels.

PMH clinicians map group at high risk for aggressive, 'hidden' prostate cancer

Clinical researchers at Princess Margaret Hospital (PMH) can now answer the question that baffles many clinicians – why do some men with elevated prostate specific antigen (PSA) levels who are carefully monitored and undergo repeated negative biopsies still develop aggressive prostate cancer?

Major health care challenges persist for D.C. children despite high rates of health insurance coverage, RAND study finds

Despite high rates of health insurance coverage among children in the District of Columbia, children's access to health care is inadequate and poses a significant health problem for the city's young residents, particularly those who are publicly insured, according to a RAND Corporation study issued today.

College architecture team introduces solar-powered smart house

After two years of design, experimentation, fund-raising and building, the University of Arizona's Solar Decathlon team has completed construction of its 800-square-foot solar-powered house on the National Mall in Washington, D.C.

The UA's team will compete with entries from 14 other states, Puerto Rico, Canada, Germany and Spain.

The Solar Decathlon effort is but one of the UA's efforts to broaden the horizon of sustainable architecture and building.

New mobile lab allows MSU researchers to study air quality, health effects

EAST LANSING, Mich. — A new mobile air research laboratory will help a team of researchers led by a Michigan State University professor better understand the damaging health effects of air pollution and why certain airborne particles – emitted from plants and vehicles – induce disease and illness.

Jack Harkema, a University Distinguished Professor of pathobiology and diagnostic investigation in the College of Veterinary Medicine, will deploy the new 53-foot, 36,000-pound center – dubbed "AirCARE 2" – throughout southern Michigan, including metropolitan Detroit.

Insured African-Americans more likely to use emergency room than other insured groups

Health insurance, and the access it provides to a primary care physician, should reduce the use of a major driver of health care costs: the emergency room.

Yet in a policy brief released today by the UCLA Center for Health Policy Research, researchers found that in California, privately insured African Americans enrolled in HMOs are far more likely to use the ER and to delay getting needed prescription drugs than HMO-insured members of other racial and ethnic groups. The research was funded by the California Office of the Patient Advocate.

New aluminum-water rocket propellant promising for future space missions

WEST LAFAYETTE, Ind. - Researchers are developing a new type of rocket propellant made of a frozen mixture of water and "nanoscale aluminum" powder that is more environmentally friendly than conventional propellants and could be manufactured on the moon, Mars and other water-bearing bodies.

The aluminum-ice, or ALICE, propellant might be used to launch rockets into orbit and for long-distance space missions and also to generate hydrogen for fuel cells, said Steven Son, an associate professor of mechanical engineering at Purdue University.

Peering under the ice of a collapsing polar coast

Starting this month, a giant NASA DC-8 aircraft loaded with geophysical instruments and scientists will buzz at low level over the coasts of West Antarctica, where ice sheets are collapsing at a pace far beyond what scientists expected a few years ago. The flights, dubbed Operation Ice Bridge, are an effort by NASA in cooperation with university researchers to image what is happening on, and under, the ice, in order to estimate future sea-level rises that might result.

Obese children at significantly greater risk for post-adenotonsillectomy complications

San Diego, CA – Obesity in children significantly increases the risk of major and minor respiratory complications following surgery to correct sleep disordered breathing (SDB), according to new research presented at the 2009 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO, in San Diego, CA.

Researchers create smaller and more efficient nuclear battery

COLUMBIA, Mo. – Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

Specialty hospitals cherry-pick patients, exaggerate success, says INFORMS meeting paper

Although many specialized hospitals deliver better and faster services in cardiac care and other specialties, a paper being presented at the annual meeting of the Institute for Operations Research and the Management Sciences (INFORMS®) maintains that these hospitals cherry-pick patients to achieve these results, and that average patients actually receive worse care.

Injury and hazards in home health care nursing are a growing concern

October 5, 2009 -- Patients continue to enter home healthcare ''sicker and quicker," often with complex health problems that may require extensive nursing care. This increases the risk of needlestick injuries in home healthcare nurses. While very few studies have focused on the risks of home healthcare, it is the fastest growing healthcare sector in the U.S. In a recent study, led by researchers at Columbia University Mailman School of Public Health, the rate of needlestick-type injuries was 7.6 per 100 nurses.
