[ad_1] QUT researchers have developed an innovative method for detecting koala populations using drones and infrared imaging that is more reliable and less invasive than traditional animal population monitoring techniques. In the study, published in Nature journal Scientific Reports, the researchers detail the technique that involves an algorithm for locating the koalas using drones that…
[ad_1] Scientists from the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg and from the German Cancer Research Center (DKFZ) have been able to rejuvenate stem cells in the brain of aging mice. The revitalised stem cells improve the regeneration of injured or diseased areas in the brain of old mice. The…
[ad_1] Researchers at Duke-NUS Medical School and their colleagues have identified a surprising interaction between dengue and Zika viruses that sheds lights on the significant fetal brain abnormalities linked to Zika virus. The researchers found that fetal mouse brain damage was much worse if the mothers infected with Zika also had dengue antibodies. They further…
[ad_1] Researchers have shed light on the distribution of Japanese eel by analyzing environmental DNA (eDNA) from small samples of river water. This could enable faster and more effective surveys of Japanese eel populations, and help to conserve this endangered species. The finding was published on February 27 in Aquatic Conservation: Marine and Freshwater Ecosystems.…
[ad_1] Temperatures in the Arctic are rising twice as fast as in the rest of the world, causing permafrost soils to thaw. Permafrost peatlands are biogeochemical hot spots in the Arctic as they store vast amounts of carbon. Permafrost thaw could release part of these long-term immobile carbon stocks as the greenhouse gases carbon dioxide…
[ad_1] A team led by Ludwig-Maximilians-Universitaet (LMU) in Munich paleontologist Adriana López-Arbarello has identified three hitherto unknown fossil fish species in the Swiss Alps, which provide new insights into the diversification of the genus Eosemionotus. Monte San Giorgio in the Swiss canton of Ticino is one of the most important known sources of marine fossils…
[ad_1] A new measurement approach proposed by scientists at the National Institute of Standards and Technology (NIST) could lead to a better way to calibrate computed tomography (CT) scanners, potentially streamlining patient treatment by improving communication among doctors. The approach, detailed in a research paper in the journal PLOS ONE, suggests how the X-ray beams…
[ad_1] Satellite imagery, carbon dioxide measurements, and computer models all help scientists understand how climate and carbon dynamics are changing in the world’s forests. But the technology powering these high-tech data only stretches back about thirty years, limiting our picture of long-term change. A new study in Nature Communications by scientists from the Harvard Forest,…
[ad_1] Triple-negative breast cancers are more likely than other breast cancer types to metastasize and are especially likely to go the brain in younger women. Researchers have tested various hypotheses to explain this danger. One idea that has gotten little attention is the thought that estrogen might be to blame. After all, triple negative breast…
[ad_1] McMaster researchers, working with partners at other universities, have created a motion-powered, fireproof sensor that can track the movements of firefighters, steelworkers, miners and others who work in high-risk environments where they cannot always be seen. The low-cost sensor is about the size of a button-cell watch battery and can easily be incorporated into…
