Fisheries management has often been characterized by regulatory policies that result in panaceas--broad based policy solutions that are expected to address several problems, which result in unintended consequences.
BOSTON, Aug. 20, 2018 -- Nearly 700 million people suffer from mosquito-borne diseases -- such as malaria, West Nile, Zika and dengue fever -- each year, resulting in more than 1 million deaths. Increasingly, many species of mosquitoes have become resistant to the popular pyrethroid-based insecticides. Today, researchers report a new class of mosquito repellents based on naturally occurring compounds that are effective in repelling mosquitoes with potentially fewer environmental side effects than existing repellents.
BOSTON, Aug. 20, 2018 -- Scientists report they have successfully developed and tested the world's first ultrathin artificial retina that could vastly improve on existing implantable visualization technology for the blind. The flexible device, based on very thin 2D materials, could someday restore sight to the millions of people with retinal diseases. And with a few modifications, the device could be used to track heart and brain activity.
BOSTON, Aug. 20, 2018 -- Saliva is crucial for tasting and digesting food, but scientists have now found that it may have another, more subtle role. Salivary proteins could be part of a feedback loop that influences how food tastes to people -- and by extension, what foods they're willing to eat. The researchers hope that, one day, their findings could help consumers stick to a healthier diet.
Be it heavy downpours or super-hot spells, summer weather becomes more persistent in North America, Europe and parts of Asia. When those conditions stall for several days or weeks, they can turn into extremes: heatwaves resulting in droughts, health risks and wildfires; or relentless rainfall resulting in floods. A team of scientists now presents the first comprehensive review of research on summer weather stalling focusing on the influence of the disproportionally strong warming of the Arctic as caused by greenhouse-gas emissions from burning fossil fuels.
BOSTON, Aug. 19, 2018 -- The life-threatening bacteria called MRSA can cripple a hospital since it spreads quickly and is resistant to treatment. But scientists report that they are now making advances in a new technique that avoids antibiotics. Instead, they are using light to activate oxygen, which then wipes out antibiotic-resistant bacteria. The method also could be used to treat other microbial infections, and possibly even cancer.
BOSTON, Aug. 19, 2018 -- In remote areas of the world or in regions with limited resources, everyday items like electrical outlets and batteries are luxuries. Health care workers in these areas often lack electricity to power diagnostic devices, and commercial batteries may be unavailable or too expensive. New power sources are needed that are low-cost and portable. Today, researchers report a new type of battery -- made of paper and fueled by bacteria --- that could overcome these challenges.
The new treatment will serve as both diagnosis and treatment of malignant tumors. This breakthrough in the technologies of cancer diagnosis and treatment was made by an interdisciplinary Russian-German collaboration of chemists, physicists, and biologists from NUST MISIS, Lomonosov Moscow State University, Pirogov Russian National Research Medical University (RNRMU), and the University of Duisburg-Essen (Germany).
Researchers at Tokyo Institute of Technology have honed in on an enzyme belonging to the glycerol-3-phosphate acyltransferase (GPAT) family as a promising target for increasing biofuel production from the red alga Cyanidioschyzon merolae.
Scientists have confirmed that the 3.4 billion year old Strelley Pool microfossils had chemical characteristics similar to modern bacteria. This all but confirms their biological origin and ranks them amongst the world's oldest microfossils. The work is presented at the Goldschmidt geochemistry conference in Boston, with simultaneous publication in the peer-reviewed journal Geochemical Perspectives Letters (see below for reference).
