Better blood transfusions for preterm babies Posted: 23 Nov 2012 10:26 AM PST Results of new research are a promising step forward in helping to improve the quality of life-saving blood transfusions for preterm babies, by reducing the likelihood of adverse inflammatory responses to the blood.

Materials science: One size cloaks all Posted: 23 Nov 2012 10:26 AM PST Scientists have developed a metamaterial invisibility cloak that can adapt to hide different sized objects. The findings represent a useful advance for more practical applications of metamaterial cloaking.

Polymer chemistry: Dual-function molecules enhance widely used chemical reaction while reducing harmful by-products Posted: 23 Nov 2012 10:26 AM PST Production of biocompatible and super-absorbent materials may become easier. Using a modification to the high-precision technique known as atom transfer radical polymerization (ATRP), which links molecules into long chains, researchers have developed new compounds that can directly polymerize acidic vinyl monomers, such as acrylic acid.

Wireless networks: Mobile devices keep track Posted: 23 Nov 2012 10:26 AM PST A more sensitive technique for determining user position could lead to improved location-based mobile services.

Green chemistry: Waste from palm oil extraction can be converted into useful sugar Posted: 23 Nov 2012 10:26 AM PST The waste plant materials remaining from palm oil extraction processes can now be converted into a useful sugar.

Improving 3-D image capture in real time Posted: 23 Nov 2012 07:37 AM PST Researchers have developed a technique to improve the capture in real time of three-dimensional images. The work has applications in aeronautics, the automotive sector and operating rooms.

Hubble eyes a loose spiral galaxy Posted: 23 Nov 2012 06:37 AM PST The NASA/ESA Hubble Space Telescope has spotted the spiral galaxy ESO 499-G37, seen here against a backdrop of distant galaxies, scattered with nearby stars.

New test may improve cervical cancer detection Posted: 23 Nov 2012 06:27 AM PST Routine smear tests have considerably reduced the number of cases of cervical cancer, but despite intensive screening women still die from the disease every year. Researchers have developed new methods of minimizing the number of missed cases and making diagnosis more reliable.

Nutrients from farmed salmon waste can feed new marine industry Posted: 23 Nov 2012 06:27 AM PST Waste from salmon production is currently being discharged into Norwegian coastal waters. Researchers say this is a resource that should be exploited for new biological production.

Drained wetlands give off same amount of greenhouse gases as industry Posted: 23 Nov 2012 06:27 AM PST Drained wetlands in Sweden account for the same amount of greenhouse gas emissions as Swedish industry.

Pilot whales use synchronized swimming when they sense danger Posted: 23 Nov 2012 06:27 AM PST Scientists have observed the behavior of various groups of cetaceans including long-finned pilot whales in the Strait of Gibraltar and Cape Breton in Canada. These whales were found to use synchronized swimming when they identify the presence of an external threat.

Low-cost, finger-nail sized radar Posted: 23 Nov 2012 06:27 AM PST Researchers have squeezed radar technology into a low-cost fingernail-sized chip package that promises to lead to a new range of distance and motion sensing applications. The novel device could have important uses in the automotive industry, as well as mobile devices, robotics and other applications.

Climate change evident across Europe, confirming urgent need for adaptation Posted: 23 Nov 2012 06:21 AM PST Climate change is affecting all regions in Europe, causing a wide range of impacts on society and the environment. Further impacts are expected in the future, potentially causing high damage costs, according to the latest assessment.

Norway's oil industry working in extreme conditions Posted: 23 Nov 2012 06:21 AM PST The northward shift of Norway's oil industry means it must adjust to temperatures down to -30°C, storms, sleet and snow, and drift ice. And to the blackest night.

New insights into virus proteome: Unknown proteins of the herpesvirus discovered Posted: 23 Nov 2012 06:21 AM PST The genome encodes the complete information needed by an organism, including that required for protein production. Viruses, which are up to a thousand times smaller than human cells, have considerably smaller genomes. Using a type of herpesvirus as a model system scientists have shown that the genome of this virus contains much more information than previously assumed. The researchers identified several hundred novel proteins, many of which were surprisingly small.

Electricity from the marshes Posted: 23 Nov 2012 06:21 AM PST An unexpected source of new, clean energy has been found: the Plant-Microbial Fuel Cell that can generate electricity from the natural interaction between living plant roots and soil bacteria. The technique already works on a small scale and will soon be applied in larger marshland areas throughout the world.

Le Rouge et le Noir: Where the black dahlia gets its color Posted: 22 Nov 2012 04:54 PM PST The molecular mechanisms whereby a spectrum of dahlias, from white to yellow to red to purple, get their color are already well known, but the black dahlia has hitherto remained a mystery. Now, a study reveals for the first time that the distinctive black-red coloring is based on an increased accumulation of anthocyanins as a result of drastically reduced concentrations of flavones.

Scientists design a revolutionary data storage device Posted: 22 Nov 2012 06:53 AM PST Scientists have designed one of the most advanced data storage devices in the world.

Adults with ADHD commit fewer crimes when on medication Posted: 22 Nov 2012 06:51 AM PST Criminal behaviour in people with ADHD (attention deficit hyperactivity disorder) dropped sharply during periods when they were on medication, according to a new extensive registry study.

Poor and often inaccurate web info on 'designer vagina' procedures Posted: 21 Nov 2012 06:03 PM PST The quality of internet information available for women opting for 'designer vagina' procedures is 'poor,' and in some cases, inaccurate, reveals a small study.

Male bias persists in female-rich science conferences Posted: 21 Nov 2012 06:02 PM PST Women scientists in primatology are poorly represented at symposia organized by men, but receive equal representation when symposia organizers are women or mixed groups, according to new research.

MicroRNA makes triple-negative breast cancer homesick Posted: 21 Nov 2012 06:02 PM PST Carcinoma cells are epithelial cells gone bad and have learned to act like neurons, inappropriately activating TrkB signaling to escape the programmed cell death known as anoikis. They do it by a mutation that nixes production of a microRNA called miR-200c. When researchers reintroduced miR-200c to aggressive, triple-negative breast cancer cells, these cells regained sensitivity to anoikis and self-destructed.

Stem cells develop best in 3-D Posted: 21 Nov 2012 12:33 PM PST Scientists are discovering the best way to make stem cells develop into insulin-producing cells. In the long term this new knowledge can improve diabetes treatment with cell therapy.
