TALLAHASSEE, Fla. -- Researchers examining subglacial waters both from Antarctica and Greenland found that these waters have higher concentrations of important, life-sustaining elements than previously thought, answering a big unknown for scientists seeking to understand the Earth's geochemical processes.
WASHINGTON--Weather systems responsible for transporting moisture from the tropics to temperate regions in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarctica, according to new research.
According to the World Health Organization (WHO), mental health illness and substance use disorders are key contributors to disability in young adulthood, and disparities in substance use persist along levels of academic achievement and socioeconomic status.
A research team from the Center for Design, Manufacturing and Materials at Skoltech has recently published a study focusing on multifunctional materials created through the addition of carbon nanoparticles to polymer matrices, designed to allow self-diagnostic monitoring through an inexpensive technique.
The largest aggregation of fishes ever recorded in the abyssal deep sea was discovered by a team of oceanographers from the University of Hawai'i at Mānoa (UH, USA), Monterey Bay Aquarium Research Institute (MBARI, USA) and the National Oceanography Centre (NOC, UK). Their findings were published recently in Deep-Sea Research.
Trapping and controlling electrons in bilayer graphene quantum dots yields a promising platform for quantum information technologies. Researchers at UC Santa Cruz have now achieved the first direct visualization of quantum dots in bilayer graphene, revealing the shape of the quantum wave function of the trapped electrons.
The results, published November 23 in Nano Letters, provide important fundamental knowledge needed to develop quantum information technologies based on bilayer graphene quantum dots.
VIRTUAL MEETING (CST), November 22, 2020 -- Global population and urbanization have boomed over the last few decades. With them came scores of new tall buildings, drones, more energy-efficient ventilation systems, and planned air taxis by Uber and other companies. But these technological advancements must contend with a natural physical phenomenon: wind.
Mechanical engineer Michael Gollner and his graduate student, Sriram Bharath Hariharan, from the University of California, Berkeley, recently traveled to NASA's John H. Glenn Research Center in Cleveland, Ohio. There, they dropped burning objects in a deep shaft and study how fire whirls form in microgravity. The Glenn Center hosts a Zero Gravity Research Facility, which includes an experimental drop tower that simulates the experience of being in space.
Up to one-quarter of people who suffer child sexual abuse might be passed over for treatment because of current screening procedures, according to UC Riverside psychology researchers.
Their just-published study also finds that whether survivors of child sexual abuse identify themselves as abuse survivors influences the outcomes they experience in young adulthood.
Giving nurse practitioners the authority to prescribe buprenorphine has brought that gold standard treatment for opioid addiction to people who might not have had access to it before, according to a new study led by Tracy Klein, PhD, associate professor at the Washington State University College of Nursing in Vancouver.
Researchers from Kaunas University of Technology (KTU), Lithuania came up with the idea on how to measure fluctuating blood potassium levels non-invasively, through electrocardiogram. The researchers claim that their method may become a digital biomarker in the future for managing electrolyte levels. This would be a huge step towards preventing potentially life-threatening conditions among people who suffer from chronic kidney disease.
Excessive calcium contributes to harmful inflammation in ischemic stroke, and targeting it may provide doctors with a new way to improve patient outcomes, new research from the University of Virginia School of Medicine suggests.
Petr Tvrdik, PhD, has found that immune cells called microglia are flooded with waves of calcium in the wake of ischemic strokes, which are strokes caused by disruption of blood flow to the brain. These calcium waves, he determined, trigger damaging inflammation that may worsen the stroke's effects.
Young children of African ancestry are more at risk of developing obesity if they possess a genetic variant that reduces their ability to produce the hormone leptin. Adults with the variant do not have the same risk, suggesting that leptin plays a role in the development of obesity at a young age but the obesity does not continue into adulthood.
Palaeontologists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the University of Calgary in Canada have provided new proof of parallel evolution: conodonts, early vertebrates from the Permian period, adapted to new habitats in almost identical ways despite living in different geographical regions. The researchers were able to prove that this was the case using fossil teeth found in different geographical locations.
Between April and June of 2019, 10 research teams composed of 34 international and Nepali scientists journeyed toward the summit of Mount Everest as part of the 2019 National Geographic and Rolex Perpetual Planet Everest Expedition. Early results from this expedition, publishing November 20 in the journal One Earth, look at the impacts of climate change and human activity on Mount Everest, including glacier loss, precipitation changes, the presence of microplastics on the mountain, and more. Highlights from the findings include:
