Early-warning sensor systems that can test and track serious infectious diseases – such as major flu epidemics, MRSA and HIV – using mobile phones and the internet are being developed by a major new Interdisciplinary Research Collaboration (IRC) led by UCL.
The new £11 million IRC, funded by the Engineering and Physical Sciences Research Council (total investment £16 million), will develop mobile health technologies that allow doctors to diagnose and track diseases much earlier than ever before. (more…)
Sometimes cost saving comes in nanoscale packages.
A new procedure that thickens and thins fluid at the micron level could save consumers and manufacturers money, particularly for soap products that depend on certain molecules to effectively deal with grease and dirt. Researchers at the University of Washington publishedtheir findings online April 9 in the Proceedings of the National Academy of Sciences.
Read the back of most shampoos and dishwashing detergents and you’ll find the word “surfactant” in the list of active ingredients. Surfactant molecules are tiny, yet they are the reason dish soap can attack an oily spot and shampoo can rid the scalp of grease. (more…)
Combined research efforts by scientists involved in the Gulf of Maine Toxicity (GOMTOX) project, funded by NOAA’s Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, and administered by the National Centers for Coastal Ocean Science (NCCOS), have led to enhanced understanding of toxic algal blooms on Georges Bank. This new information, coupled with an at-sea and dockside testing protocol developed through collaboration between GOMTOX and U.S. Food and Drug Administration (FDA) investigators, has allowed fishermen to harvest ocean quahogs and surf clams in these offshore waters for the first time in more than two decades.
The shellfish industry estimates the Georges Bank fishery can produce up to 1 million bushels of surf clams and ocean quahogs a year, valued $10 – 15 million annually. “There is a billion dollars’ worth of shellfish product on Georges Bank that is property of the United States but that can’t be harvested because of the threat of toxicity, and 99.9% of the time, it is good wholesome product,” says Dave Wallace of North Atlantic Clam Association and a GOMTOX participant. “In an unusual and unique partnership, we worked with GOMTOX scientists, the FDA, and the states of Massachusetts, Rhode Island, New Jersey and Delaware and now that huge resource can go into commerce, which helps the entire country.” (more…)
For some solar cells, the future may be fluorescent.
Scientists at Yale have improved the ability of a promising type of solar cell to absorb light and convert it into electrical power by adding a fluorescent organic dye to the cell layer. This squaraine dye boosts light absorption and recycles electrons, improving the conversion of light into energy. The results suggest a new route for the development of lower-cost, higher-efficiency photovoltaics, the scientists said.
“People can apply our approach in designing advanced solar cells with higher efficiencies,” said André D. Taylor, the assistant professor of chemical and environmental engineering at Yale who led the research, published May 5 online in the journal Nature Photonics. (more…)
Scientists heard their first pops last week in an experiment that searches for signs of dark matter in the form of tiny bubbles.
They will need to analyze them further in order to discern whether dark matter caused any of the COUPP-60 experiment’s first bubbles at the SNOLAB underground science laboratory in Ontario, Canada. Dark matter accounts for nearly 90 percent of all matter in the universe, yet it is invisible to telescopes.
“Our goal is to make the most sensitive detector to see signals of particles that we don’t understand,” said Hugh Lippincott, a postdoctoral scientist with Fermi National Accelerator Laboratory. Lippincott has spent much of the past several months leading the installation of the one-of-a-kind detector at SNOLAB, 1.5 miles underground. (more…)
Since its inception in 1909, University of Minnesota Extension has worked with farmers to find solutions to their biggest challenges. And, since we all eat—our biggest challenges. For the past 25 years, Extension has shared the U’s expertise by educating agriculture professionals, who in turn have the most influence on crop farmers today.
Keeping agriculture professionals on top of current research helps ensure economically and environmentally responsible cropping decisions are made throughout the state. (more…)
Oil and gas development continues to press into the most remote corners of the western Amazon, one of the most biologically and culturally diverse zones on Earth. Now a study proposes a new 10-point, best-practice framework that combines technical engineering criteria with consideration of ecological and social concerns to reduce the negative impacts of Amazonian hydrocarbon exploration and production.
The researchers say, for example, that by using extended reach drilling (ERD), a technique to reach a larger subsurface area from one surface drilling location, it is possible to greatly reduce the total number of needed drilling platforms and access roads for a given project. (more…)
Improvised explosive devices (IEDs) are becoming a global problem for the U.S. armed forces. To prevent injuries to soldiers and provide better care to those who are injured, the U.S. military is striving to better understand how blasts impact the human body.(more…)
