Limiting polyunsaturated fatty acid levels in pregnancy may influence body fat of children

Southampton researchers have demonstrated that mothers who have higher levels of n-6 polyunsaturated fatty acids (PUFAs), which are found in cooking oils and nuts, during pregnancy have fatter children.

The study, carried out by the Medical Research Council (MRC) Lifecourse Epidemiology Unit, University of Southampton, assessed the fat and muscle mass of 293 boys and girls at four and six years, who are part of the Southampton Women's Survey (SWS), a large prospective mother-offspring cohort.

Southampton scientist develops strongest, lightest glass nanofibres in the world

The University of Southampton's Optoelectronics Research Centre (ORC) is pioneering research into developing the strongest silica nanofibres in the world.

Globally the quest has been on to find ultrahigh strength composites, leading ORC scientists to investigate light, ultrahigh strength nanowires that are not compromised by defects. Historically, carbon nanotubes were the strongest material available, but high strengths could only be measured in very short samples just a few microns long, providing little practical value.

Engineering alternative fuel with cyanobacteria

ALBUQUERQUE, N.M. — Sandia National Laboratories Truman Fellow Anne Ruffing has engineered two strains of cyanobacteria to produce free fatty acids, a precursor to liquid fuels, but she has also found that the process cuts the bacteria's production potential.

Online message boards provide outlets for mothers' concerns, MU researcher says

COLUMBIA, Mo. –Parenting infants and toddlers can be challenging, and for generations, mothers have turned to other moms for advice. Now, with the availability of the Internet, mothers are consulting each other using modern venues: online message boards. Research from the University of Missouri indicates online discussion boards provide safe environments for mothers to anonymously express child-rearing concerns and receive support from other moms.

Scientists use marine robots to detect endangered whales

Two robots equipped with instruments designed to "listen" for the calls of baleen whales detected nine endangered North Atlantic right whales in the Gulf of Maine last month. The robots reported the detections to shore-based researchers within hours of hearing the whales (i.e., in real time), demonstrating a new and powerful tool for managing interactions between whales and human activities.

Tree seeds offer potential for sustainable biofuels

Tree seeds, rather than biomass or fuel crop plants, could represent an abundant source of renewable energy, according to research published in the International Journal of Automotive Technology and Management. The study suggests that seeds from the Indian mahua and sal trees have almost as good a thermal efficiency as biodiesel but would produce lower emissions of carbon monoxide, waste hydrocarbons and NOx (nitrogen oxides).

Supply problems spark search for new ways to make magnets -- not the 'fridge' variety

Mention magnets, and most people think of trivial applications of those pieces of metal, like holding family photos and reminder notes on the refrigerator. An article on magnets in the current edition of Chemical & Engineering News (C&EN), however, focuses on the critical role magnets play in the real world and the search for new materials to make them. C&EN is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.

Inside DayGlo: A video tour of the world's most colorful factory

A new American Chemical Society (ACS) video provides a behind-the-scenes-look at the DayGlo Color Corp. factory, producer of the fluorescent paints that light up traffic cones, black light posters, hula-hoops and other products. The video, the latest episode of the award-winning Bytesize Science series from the world's largest scientific society, is at www.BytesizeScience.com.

'Tricorder' invention could put medical diagnosis and terrorism prevention in the palm of the hand

COLUMBIA, Mo. -- The hand-held scanners, or tricorders, of the Star Trek movies and television series are one step closer to reality now that a University of Missouri engineering team has invented a compact source of X-rays and other forms of radiation. The radiation source, which is the size of a stick of gum, could be used to create inexpensive and portable X-ray scanners for use by doctors, as well as to fight terrorism and aid exploration on this planet and others.

A new point of reference for offshore energy development

AUSTIN, Texas - A new Department of Energy research facility could help bring the U.S. closer to generating power from the winds and waters along America's coasts and help alleviate a major hurdle for offshore wind and ocean power development.

Will Shaw, an atmospheric scientist at DOE's Pacific Northwest National Laboratory, will describe plans for the facility at an 11:45 a.m. talk today at the 93rd American Meteorological Society Annual Meeting, which runs through Thursday in Austin, Texas.

New biochip technology uses tiny whirlpools to corral microbes

WEST LAFAYETTE, Ind. - Researchers have demonstrated a new technology that combines a laser and electric fields to create tiny centrifuge-like whirlpools to separate particles and microbes by size, a potential lab-on-a-chip system for medicine and research.

Concentrated solar power with thermal energy storage can help utilities' bottom line, study shows

The storage capacity of concentrating solar power (CSP) can add significant value to a utility company's optimal mix of energy sources, a new report by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) suggests.

Study finds flame retardant pollutants at far-flung locations

BLOOMINGTON, Ind. -- Chemicals used as flame retardants are present as environmental pollutants at locations around the globe, including remote sites in Indonesia, Nepal and Tasmania, according to a study by researchers from the Indiana University School of Public and Environmental Affairs.

The study, published this month in the journal Environmental Science and Technology, makes use of a novel but highly effective sampling technique: measuring concentrations of the chemicals in the bark of trees, which absorbs compounds in both vapor and particle phases.

3-D color X-Ray imaging radically improved for identifying contraband, corrosion or cancer

Scientists at The University of Manchester have developed a camera that can be used to take powerful three dimensional colour X-ray images, in near real-time, without the need for a synchrotron X-ray source.

Its ability to identify the composition of the scanned object could radically improve security screening at airports, medical imaging, aircraft maintenance, industrial inspection and geophysical exploration.

Corn could help farmers fight devastating weed

Versatile and responsive to management, corn is grown throughout the world for everything from food to animal feed to fuel. A new use for corn could soon join that list, as researchers in China investigate the crop's ability to induce "suicidal germination" in a devastating parasitic weed.
