Lesbian, gay and bisexual (LGB) individuals report higher rates of medical, non-medical, and illegal stimulant use compared to heterosexuals, mirroring patterns seen in other substance use. The study by Columbia University Mailman School of Public Health researchers provides the most detailed picture to date on stimulant use by LGB subgroups and gender. Findings are published in the American Journal of Preventive Medicine.
Survey of geosynchronous orbital debris led by University of Warwick found over 75% of debris detected could not be matched to known objects in public satellite catalogues
Astronomers are calling for more regular surveys with large telescopes to help quantify the risks posed to active satellites
Many of the objects detected show optical signatures of tumbling, providing insight into the dynamical evolution of debris within the geosynchronous environment
WASHINGTON--Scientists have spotted a once-in-a-century climate anomaly during World War I that likely increased mortality during the war and the influenza pandemic in the years that followed.
Well-documented torrential rains and unusually cold temperatures affected the outcomes of many major battles on the Western Front during the war years of 1914 to 1918. Most notably, the poor conditions played a role in the battles of Verdun and the Somme, during which more than one million soldiers were killed or wounded.
ABERDEEN PROVING GROUND, Md. -- Future technology may be able to monitor and modify the brain to produce enhanced team performance, while increasing the efficiency and accuracy of decisions.
The U.S. Army may be able to use this information to enhance future operations.
"We are working toward fused human-technology systems that work synergistically to not only impact perceptions, decisions and actions of the Soldier, but also to enhance the hybrid human system's capabilities for rapid and adaptive decision making," said Dr. Javier Garcia, an Army neuroscientist.
Kidney injury is a dreaded complication in patients hospitalized for COVID-19, with more than a third of patients ending up in need of dialysis. Patients with COVID-19-related kidney injury are also at much higher risk of death.
Two scientists from IP2I (CNRS/Université Claude Bernard Lyon 1), in collaboration with a researcher from the University of Southern Denmark and the University of Naples Federico II, have developed a new mathematical model inspired by high energy physics to predict the next waves of the Covid-19 pandemic. The extension of this technique to epidemiology, referred to as the epidemic Renormalisation group,[1] and widely used in particle physics and condensed matter physics, yields a mathematical model that can characterise the evolution of the pandemic across European territories.
People infected by the novel coronavirus can have symptoms that range from mild to deadly. Now, two new analyses suggest that some life-threatening cases can be traced to weak spots in patients' immune systems.
More than 10 percent of young and healthy people who develop severe COVID-19 have misguided antibodies that attack not the virus, but the immune system itself, new research shows. Another 3.5 percent, at least, carry a specific kind of genetic mutation.
Twin studies suggest impaired type I interferon signaling may contribute to severe COVID-19 symptoms
Two new studies report specific mechanisms of impaired type I interferon (IFN) signaling in some hospitalized patients suffering from severe cases of COVID-19, suggesting that screens for these defects could help identify patients at the highest risk of life-threatening complications from SARS-CoV-2 infection.
Researchers from North Carolina State University have demonstrated the utility of artificial intelligence (AI) in identifying and categorizing neural degeneration in the model organism C. elegans. The tool uses deep learning, a form of AI, and should facilitate and expedite research into neural degeneration.
Tiny crystals, ten thousand times thinner than a human hair, can cause explosive volcanic eruptions. This surprising connection has recently been discovered by a German-British research team led by Dr. Danilo Di Genova from the Bavarian Research Institute of Experimental Geochemistry & Geophysics (BGI) at the University of Bayreuth. The crystals increase the viscosity of the underground magma. As a result, a build-up of rising gases occurs. The continuously rising pressure finally discharges in massive eruptions.
Elastic can stretch too far and that could be problematic in wearable sensors. A team of researchers at Yokohama National University has proposed a fix to prevent too much stretching while improving the sensing ability of electronics. This could lead to advanced prosthetics or disaster recovery robotics.
They published their results on July 29 in the Scientific Reports.
Through a one-of-a-kind experiment at the Department of Energy's Oak Ridge National Laboratory, nuclear physicists have precisely measured the weak interaction between protons and neutrons. The result quantifies the weak force theory as predicted by the Standard Model of Particle Physics.
Black, South Asian and Aboriginal populations from disadvantaged socioeconomic backgrounds in Canada are nearly four times more likely to have three or more medical conditions that have been identified as risk factors for severe illness from COVID-19.
BOSTON - Emergency departments of hospitals generate significant amounts of environmentally harmful waste which could be reduced through basic changes to disposal policies and practices, while producing lower operating costs, researchers from Massachusetts General Hospital (MGH) have found.
