Innovative sensors have been developed that will dramatically improve the ability to spot early warning signs of corrosion in concrete.

More resilient and much longer lasting than traditional corrosion sensors they will make monitoring the safety of structures such as bridges and vital coastal defences much more effective.

The carbon steel bars used to reinforce submerged concrete in tidal zone areas are at particular risk of corrosion caused by wet conditions*.

Taking inspiration from the yellow fattail scorpion, which uses a bionic shield to protect itself against scratches from desert sandstorms, scientists have developed a new way to protect the moving parts of machinery from wear and tear. A report on the research appears in ACS' journal Langmuir.

Scientists at Queen's University Belfast have made a major breakthrough in developing sensors which dramatically improve the ability to spot early warning signs of corrosion in concrete.

The sensors, which are more resilient and much longer lasting than traditional corrosion sensors, will make monitoring the safety of structures such as bridges and vital coastal defences much more effective.

The research assesses the benefits of white roofs and aims to help residential, commercial and industrial building owners determine if white roofs are suitable for their buildings and guide them through the best materials to use.

Lord Mayor Robert Doyle said Council had already put the research into practice by trialling a white roof on its ArtPlay building.

Eating food fried in olive or sunflower oil is not linked to heart disease or premature death, finds a paper published on bmj.com today.

The authors stress, however, that their study took place in Spain, a Mediterranean country where olive or sunflower oil is used for frying and their results would probably not be the same in another country where solid and re-used oils were used for frying.

Amsterdam, NL -- The sudden popularity of tablet computers such as the Apple iPad® has not allowed for the development of guidelines to optimize users' comfort and well-being. In a new study published in Work: A Journal of Prevention, Assessment, and Rehabilitation, researchers from Harvard School of Public Health, Microsoft Corporation, and Brigham and Women's Hospital report that head and neck posture during tablet computer use can be improved by placing the tablet higher to avoid low gaze angles, and through the use of a case that provides optimal viewing angles.

Scientists at USC have uncovered evidence that even when hydrothermal sea vents go dormant and their blistering warmth turns to frigid cold, life goes on.

Or rather, it is replaced.

A team led by USC microbiologist Katrina Edwards found that the microbes that thrive on hot fluid methane and sulfur spewed by active hydrothermal vents are supplanted, once the vents go cold, by microbes that feed on the solid iron and sulfur that make up the vents themselves.

COLUMBUS, Ohio – On any given weekend, at least 10 percent of students at a single college could be hosting a party, and on average, party hosts who live off campus are drinking more and engaging in more alcohol-related problem behaviors than are the students attending their bashes, research suggests.

In contrast, hosts of parties held on campus tend to drink less than do the students attending their gatherings, according to the study.

RIVERSIDE, Calif. – In August 2010, an entomologist at the University of California, Riverside discovered a tiny fairyfly wasp in upstate New York that had never been seen in the United States until then. Nearly exactly a year later, he discovered the wasp in Irvine, Calif., strongly suggesting that the wasp is well established in the country.

Called Gonatocerus ater, the wasp is about 1 millimeter long and arrived in North America from Europe. It lays its eggs inside the eggs of leafhoppers.

ALBUQUERQUE, N.M. – Research by a team of Sandia National Laboratories chemists could impact worldwide efforts to produce clean, safe nuclear energy and reduce radioactive waste.

The Sandia researchers have used metal-organic frameworks (MOFs) to capture and remove volatile radioactive gas from spent nuclear fuel. "This is one of the first attempts to use a MOF for iodine capture," said chemist Tina Nenoff of Sandia's Surface and Interface Sciences Department.

– A pair of studies by The Children's Hospital of Philadelphia (CHOP) and State Farm® identify factors that may lead teens to drive with multiple peer passengers and, then, how those passengers may affect their driver's behavior just before a serious crash. The studies were published today in the Journal of Adolescent Health.

Researchers from North Carolina State University have developed a new method for creating elastic conductors made of carbon nanotubes, which will contribute to large-scale production of the material for use in a new generation of elastic electronic devices.

The skeletal structure of the foot and ankle differs significantly between human sprinters and non-sprinters, according to Penn State researchers. Their findings not only help explain why some people are faster runners than others, but also may be useful in helping people who have difficulty walking, such as older adults and children with cerebral palsy.

EPFL scientist are among the leaders in the race to develop an industry-ready prototype of a 3D chip as well as a high-performance and reliable manufacturing method. The chip is composed of three or more processors that are stacked vertically and connected together—resulting in increased speed and multitasking, more memory and calculating power, better functionality and wireless connectivity.

Louisville, AZ—Working mothers may be busy, but they like it that way. A recent study of employed moms finds that most would work even if they didn't have to, but they're also looking for new ways to negotiate the demands of mothering and the pressures to be an "ideal" employee.
