Powerful new cells created by Cardiff University scientists from cheek lining tissue could offer the answer to disorders of the immune system. While the body's immune system protects against many diseases, it can also be harmful. Using white blood cells (lymphocytes), the system can attack insulin-producing cells, causing diabetes, or cause the body to reject transplanted organs. A team from Cardiff's School of Dentistry led by Professor Phil Stephens, with colleagues from Stockholm's Karolinska Institute, have found a new group of cells with a powerful ability to suppress ...

A group of biologists from Denmark and the US led by Jakob Christensen-Dalsgaard, University of Southern Denmark, and Catherine Carr, University of Maryland, have shown that the turtle ear is specialized for underwater hearing. The new discovery is published in Proceedings of the Royal Society B March 21st , Special features of the turtle ear – a large, air-filled middle ear and a movable tympanic disk increase its sensitivity for underwater sound. Laser measurements of disk vibrations in response to underwater sound show up to 100-fold larger vibrations of the disk than ...

The behaviour of some of the most elusive particles in the known universe can be simulated using three atoms in a lab, researchers at the Centre for Quantum Technologies (CQT) at the National University of Singapore have found. Principal Investigator Dimitris G. Angelakis and his group members Changsuk Noh and Blas Rodriguez-Lara have devised a scheme that uses the quantum states of three charged ions to simulate the 'oscillations' of neutrinos. The proposal is published in the March issue of New Journal of Physics. Neutrinos are pesky things to study: they barely interact ...

A new study suggests that climate change could pose a risk for Antarctic fur seals in their first few months of life. The study, published in the journal Physiological and Biochemical Zoology, found that changing weather conditions can impact the metabolic rates of fur seal pups. Climate models predict windier and wetter conditions in Antarctica in the coming years, and that could cause young seals to assign more energy to thermoregulation, leaving less available for growth and development. For their study, a team of scientists led by Dr. Birgitte McDonald (University ...

CINCINNATI—Health care practitioners have long understood the importance of "door to balloon" time for heart attack patients—the faster they can get the patient from the door of the hospital to a catheterization lab to open a clogged artery, the better the patient will do. But a University of Cincinnati (UC) emergency medicine researcher says it's also important to study the "medical contact to balloon" time, acknowledging the role that emergency medical services (EMS) responders play in speeding patient care. In a paper published online in the journal Academic Emergency ...

Washington, D.C.—On March 17, the tiny MESSENGER spacecraft completed its primary mission to orbit and observe the planet Mercury for one Earth-year. The bounty of surprises from the mission has completely altered our understanding of the solar system's innermost planet. As reported in one of two papers published today on Science Express, scientists have found that Mercury's core, already suspected to occupy a greater fraction of the planet's interior than do the cores of Earth, Venus, or Mars, is even larger than anticipated. The companion paper shows that the elevation ...

Physicists who have studied the mixing between two incompatible fluids have found that it is possible to control the undercurrents of one circulating fluid to optimise its exposure to the other. This work, which is about to be published in EPJ E¹, was performed by Jorge Peixinho from CNRS at Le Havre University, France, and his colleagues from the Benjamin Levich Institute, City University of New York, USA. The authors compared quantitative experimental observations of a viscous fluid, similar to honey, with numerical simulations. They focused on a fluid, which partially ...

URBANA – University of Illinois research reports that swine producers can feed distiller's dried grain with solubles (DDGS) to their pigs without concern for sulfur content. "When you buy DDGS, you don't have to be concerned about the level of sulfur it contains because there doesn't appear to be any impact on pig performance," said U of I animal sciences professor Hans Stein. According to the researcher, DDGS, a co-product of the ethanol industry, is used as a feed ingredient in diets fed to swine. To maintain a stable pH in fermentation vats, ethanol producers ...

The Defense Department, faced with cuts of what Secretary Leon Panetta said could be $487 billion over the next ten years, can find tens of billions of dollars in cost reductions by better aligning the Pentagon supply chain rather than imposing precipitous reductions to the uniformed forces, according to a former Army colonel who is speaking at a conference hosted by the Institute for Operations Research and the Management Sciences (INFORMS®), the premier organization for advanced analytics professionals. The INFORMS Military Applications Society Conference takes place ...

Could widespread conjugal visitation reduce sexual offending in prisons? It's a possibility, according to Stewart D'Alessio and his team from Florida International University in the US. Their work shows that in states where conjugal visits are permitted, there are significantly fewer instances of reported rape and other sexual offenses in their prisons. The study is published online in Springer's American Journal of Criminal Justice. At present, there are two opposing theories of the causes of sexual violence. The feminist perspective asserts that sexual violence is motivated ...

According to Cardinal Web Solutions, an Internet marketing firm in Atlanta, all business pages on Facebook will be converted to the Timeline format on March 30th 2012. While this may be the biggest change from a visual standpoint, the changes to features and the heretofore virtually unlimited versatility that has made Facebook an essential social media marketing tool will be a hard pill to swallow for many businesses. Communications sent thru Facebook by businesses are being throttled to 16% per month of current Facebook fans that have "liked" your page. This ...

It turns out you can be too thin—especially if you're a nanoscale battery. Researchers from the National Institute of Standards and Technology (NIST), the University of Maryland, College Park, and Sandia National Laboratories built a series of nanowire batteries to demonstrate that the thickness of the electrolyte layer can dramatically affect the performance of the battery, effectively setting a lower limit to the size of the tiny power sources.* The results are important because battery size and performance are key to the development of autonomous MEMS—microelectromechanical ...
