Scientists of Tomsk Polytechnic University have synthetized high-entropy carbide consisting of five various metals using a vacuum-free electric arc method. The research findings are published in the Journal of Engineering Physics and Thermophysics.
El Niño-Southern Oscillation (ENSO) is one of the most prominent ocean-atmosphere interactions that varies year-to-year. This process exerts significant impacts on global weather and climate. El Niño is the warm phase of ENSO, which can be strong, moderate, or even weak. Within the past four decades, climatologists observed three super El Niño events (1982/83, 1997/98 and 2015/16). These extreme phases impacted global climate far more than moderate or weak events.
Metamaterials that can control the refractive direction of light or absorb it to enable invisible cloaks are gaining attention. Recently, a research team at POSTECH has designed a metasurface that can control the acoustic or elastic waves. It is gaining attention as it can be used to escape from threatening earthquakes or build submarines untraceable to SONAR.
CHARLOTTESVILLE, VA (APRIL 6, 2021). New research by a team from the Cleveland Clinic and the London School of Economics and Political Science (LSE) has determined that surgeries performed late in the workweek, and those culminating in discharge to a specialty care facility, are associated with higher costs and unnecessarily longer stays in the hospital following a common elective spine surgery.
Newer is not always better; a study in CMAJ (Canadian Medical Association Journal) led by researchers at the University of Warwick shows that simple fetal heartbeat monitoring is still the best method for determining whether a baby is in distress during delivery and whether cesarean delivery is needed http://www.cmaj.ca/lookup/doi/10.1503/cmaj.202538.
Cesarean delivery is the most common surgical procedure worldwide, performed to expedite birth and avoid neonatal complications.
Legalization of recreational cannabis may be associated with an increase in fatal motor vehicle collisions based on data from the United States, and authors discuss the implications for Canada in an analysis in CMAJ (Canadian Medical Association Journal).
PITTSBURGH, April 5, 2021 - "Near-poor" Americans--people just above the federal poverty level but still well below the average U.S. income--who rely on Medicare for health insurance face high medical bills and may forgo essential health care, according to new research led by health policy scientists at the University of Pittsburgh Graduate School of Public Health. This is due to a coverage "cliff" in Medicaid, which supplements Medicare for people with incomes below poverty but excludes individuals above the federal poverty threshold, including the near-poor.
CLAREMONT, CA - Keck Graduate Institute (KGI) Assistant Professor and University of California, Berkeley Visiting Scientist Dr. Kiana Aran first introduced the CRISPR-Chip technology in 2019. Now just two years later, she has expanded on its application to develop CRISPR-SNP-Chip, which enables detection of single point mutations without amplification in Sickle Cell Disease and Amyotrophic lateral sclerosis (ALS).
A new study, out this week, could pave the way to revolutionary, transparent electronics.
Such see-through devices could potentially be integrated in glass, in flexible displays and in smart contact lenses, bringing to life futuristic devices that seem like the product of science fiction.
For several decades, researchers have sought a new class of electronics based on semiconducting oxides, whose optical transparency could enable these fully-transparent electronics.
Irvine, Calif. -- In 2019, the National Weather Service in Alaska reported spotting the first-known lightning strikes within 300 miles of the North Pole. Lightning strikes are almost unheard of above the Arctic Circle, but scientists led by researchers at the University of California, Irvine have published new research in the journal Nature Climate Change detailing how Arctic lightning strikes stand to increase by about 100 percent over northern lands by the end of the century as the climate continues warming.
Alzheimer's disease treatments that slow progression of the disease could significantly reduce the financial burden to U.S. state budgets, according to a new USC study.
The study outlines how states -- which have been hit particularly hard by the COVID-19 pandemic -- would see relief: Medicare would cover the costs of treating the disease, while Medicaid expenditures would be reduced due to fewer patients entering nursing homes.
A new publication from the Dauphin Island Sea Lab's Marine Mammal Research Program (DISL) examines how bridge-building and in-water construction activities may affect manatees and other large aquatic species. The article, which was recently published in The Journal of Wildlife Management, addresses the direct causes of injury and death and the longer-term, cumulative impacts on manatees and their habitats.
Although stratospheric ozone protects us by filtering out the sun's ultraviolet radiation, tropospheric ozone is a harmful pollutant. A new study has shown that ozone in the lower layers of the atmosphere decreases crop yields in maize and changes the types of chemicals that are found inside the leaves.
A new study published in Indoor Air provides design-based solutions on how to best use ultraviolet germicidal irradiation (UVGI) to disinfect occupied rooms without harming individuals. This research was conducted by Dorit Aviv, assistant professor of architecture and director of the Thermal Architecture Lab at the University of Pennsylvania Stuart Weitzman School of Design, Penn visiting scholar Miaomiao Hou, and Jovan Pantelic, an air quality expert at Katholieke Universiteit Leuven.
Researchers from the University of Minnesota Twin Cities College of Science and Engineering and Medical School have developed a unique head-mounted mini-microscope device that allows them to image complex brain functions of freely moving mice in real time over a period of more than 300 days.
