Biocides turn out to be less toxic for the environment if they are subjected to microencapsulation, due to the fact that this process forms shell(s) for the substance. This is the conclusion of chemist Ms Mariluz Alonso in a thesis defended at the University of the Basque Country (UPV/EHU). In this research, she chose a number of biocides and other complementary substances, seeking a micro-encapsulation which, besides being compatible with the environment, is more soluble in water, more manageable for the operator, with better conditions of conservation, and effective against ...

On June 22, 2011, the Helmholtz-Zentrum Dresden-Rossendorf set a new world record for magnetic fields with 91.4 teslas. To reach this record, Sergei Zherlitsyn and his colleagues at the High Magnetic Field Laboratory Dresden (HLD) developed a coil weighing about 200 kilograms in which electric current create the giant magnetic field – for a period of a few milliseconds. The coil survived the experiment unscathed. "With this record, we're not really that interested in reaching top field values, but instead in using it for research in materials science," explains Joachim ...

"White pasta is one example of a product which in some cases has received a bad reputation because of a high GI. However, white pasta produces just as good a blood glucose response as wholewheat pasta", says Liza Rosén, doctor in applied nutrition at Lund University in Sweden. The reason why wheat pasta has sometimes been assigned a confusingly high value is that GI only considers the entire area under the blood sugar curve. In contrast to what many believe, GI does not take fluctuations in blood sugar into account. This puts foods with a long and fairly low curve at ...

Designing fiber optic networks involves finding the most efficient way to connect phones and computers that are in different places – a costly and time-consuming process. Now researchers from North Carolina State University have developed a model that can find optimal connections 10,000 times more quickly, using less computing power to solve the problem. "Problems that used to take days to solve can now be solved in just a few seconds," says Dr. George Rouskas, computer science professor at NC State and author of a paper describing the new method. The model could solve ...

Targeted multi-drug treatments for hepatitis C patients that could stop the virus in its tracks have come a step closer, thanks to researchers at the University of Leeds, UK. The study by Dr Stephen Griffin and colleagues, published in the journal Hepatology, reveals how two prototype small molecule drugs, known as p7 inhibitors, can each attack different parts of the hepatitis C virus. Their findings suggest that p7 inhibitors could be a powerful way of suppressing hepatitis C, when used together with the latest generation of 'direct-acting' drugs. More than 170 million ...

Texts without spaces are not very legible, as they make it very difficult for the reader to identify where a word begins and where it ends. When genetic information in our cells is read and translated into proteins, the enzymes responsible for this task face a similar challenge. They must find the correct starting point for protein synthesis. Therefore, in organisms with no real nucleus, a point exists shortly before the start codon, to which the enzymes can bind particularly well. This helps them find the starting point itself. However, genes that do not have this sequence ...

It was subsequently studied how many new cells in the intervertebral ...

A cellulose powder has been used increasingly for many years against allergic rhinitis. Still, there has been a shortage of scientific evidence for its efficacy in seasonal allergic rhinitis (hay fever), particularly in children. Now, however, scientists from the Sahlgrenska Academy and the Department of Plant and Environmental Sciences at the University of Gothenburg have proven that the cellulose powder reduces symptoms of seasonal allergic rhinitis in children, without any adverse effects. The powder is produced from pine trees and forms a barrier on the mucous membrane ...

Use of vitamin D supplements during pregnancy has long been a matter of concern but now researchers writing in the Journal of Bone and Mineral Research report that even a high supplementation amount in healthy pregnant women was safe and effective in raising circulating vitamin D to a level thought by some to be optimal. The study also found no adverse effects of vitamin D supplementation, even at the highest amount, in women or their newborns. The research team, led by Dr. Bruce Hollis from the Medical University of South Carolina in Charleston, used a randomized controlled ...

Many reading tasks require individuals to not only read a document, but also to understand, learn from and retain the information in it. For this type of reading, experts recommend a process called active reading, which involves highlighting, outlining and taking notes on the text. Researchers at the Georgia Institute of Technology have developed software that facilitates an innovative approach to active reading. Taking advantage of touch-screen tablet computers, the LiquidText software enables active readers to interact with documents using finger motions. LiquidText ...

Beginning July 1, teenagers who are convicted of having consensual sex with a teen younger than 16 will no longer have their name added to Michigan's sex registry, provided they weren't more than four years older than their partner at the time of the offense. Of equal importance, the new legislation also affords people who have already been convicted of this sex crime - under the aforementioned circumstances - to petition the court for their removal from the state sex registry. "This presents a rare opportunity for many people to clear their name - people who would ...

Children and adolescents who eat candy tend to weigh less than their non-consuming counterparts, according to a new study published in Food & Nutrition Research, a peer-reviewed journal. This is potentially important news given the current state of the childhood obesity epidemic. But lead researcher Carol O'Neil, PhD, MPH, LDN, RD, Louisiana State University Agricultural Center, wants to ensure the study is put into perspective. "The study illustrates that children and adolescents who consume candy are less likely to be overweight or obese," O'Neil said. "However, ...

ESA's XMM-Newton space observatory has watched a faint star flare up at X-ray wavelengths to almost 10 000 times its normal brightness. Astronomers believe the outburst was caused by the star trying to eat a giant clump of matter. The flare took place on a neutron star, the collapsed heart of a once much larger star. Now about 10 km in diameter, the neutron star is so dense that it generates a strong gravitational field. The clump of matter was much larger than the neutron star and came from its enormous blue supergiant companion star. "This was a huge bullet of gas ...

British researchers have identified specific resistance mutations for two classes of p7 inhibitor, which may explain their lack of effectiveness in clinical trials combined with current standard of care. Study results support the role of p7 inhibitor combinations as potential components of future HCV-specific therapies and are available in the July issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases. More than 3% of the world population is infected with HCV, which causes severe liver disease. ...

This release is available in French. Montreal, June 28, 2011 —Canadians aren't the only people concerned with weather, eh? A new study from McGill and Concordia universities observed pedestrians in nine cities around the world and found people are less likely to walk when temperatures dip below zero, when there's too much rain or too much snow. Published in the journal Environment and Behavior, the study was conducted over 170 days from late fall to early summer. "A 5 degree Celsius increase in temperature was associated with a 14 per cent increase in pedestrians," ...

Lead author Philip Stouffer, an ornithologist ...

From educators to leaders in industry, there is broad agreement that U.S. schools have a crucial challenge in improving teaching and learning in science, technology, engineering and math (STEM) among students from kindergarten through high school. A background in STEM is not only essential to many current and future careers; it is also a means for citizens to understand and participate in an increasingly complex world--from understanding the challenges of environmental sustainability to addressing the need for alternative sources of energy. The NRC report, "Successful ...

New research by the University of Warwick and Humboldt university shows that the frequency of wars between states increased steadily from 1870 to 2001 by 2% a year on average. The research argues that conflict is being fed by economic growth and the proliferation of new borders. We may think the world enjoyed periods of relative freedom from war between the Cold War and 9/1 but the new research by Professor Mark Harrison from at the University of Warwick's the Centre for Competitive Advantage in the Global Economy, and Professor Nikolaus Wolf from Humboldt University, ...
