The researchers of the Institute for Atmospheric and Earth system research at the University of Helsinki have investigated how atmospheric particles are formed in the Arctic. Until recent studies, the molecular processes of particle formation in the high Arctic remained a mystery.
Methane (CH4) is the second most important greenhouse gas after carbon dioxide (CO2).
After analyzing the genomes of more 250,000 military veterans, researchers have identified 18 specific, fixed positions on chromosomes that appear associated with post-traumatic stress disorder. The findings may point to new therapeutic drug targets.
The origin of flowering plants famously puzzled Charles Darwin, who described their sudden appearance in the fossil record from relatively recent geological times as an “abominable mystery”.
A new study led by a University at Buffalo researcher has identified how specific communication among different brain regions, known as brain connectivity, can serve as a biomarker for attention deficit hyperactivity disorder (ADHD).
A pair of research papers from St. Jude Children’s Research Hospital report on a medulloblastoma clinical trial that provides insights to guide treatment and shed light on relapsed disease.
Sleep cycles in people oscillate during the 29.5-day lunar cycle: In the days leading up to a full moon, people go to sleep later in the evening and sleep for shorter periods of time. Scientists observed these oscillations in urban and rural settings — regardless of an individual’s access to electricity.
A study led by a University of Illinois Chicago researcher uses a new approach to measure precarious, or low-quality, employment in the United States. And, according to those findings, precarious employment has increased 9% between 1988 and 2016.
A University of Washington-led team has revisited and comprehensively reinterpreted radio telescope observations underlying a 2019 claim of phosphine in the atmosphere of Venus. They report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.
People with schizophrenia, a mental disorder that affects mood and perception of reality, are almost three times more likely to die from the coronavirus than those without the psychiatric illness, a new study shows. Their higher risk, the investigators say, cannot be explained by other factors that often accompany serious mental health disorders, such as higher rates of heart disease, diabetes, and smoking.
The study, which followed 240 pregnant women between March and June 2020, found that the COVID-19 mortality rate in the pregnant women was significantly higher when compared to the COVID-19 mortality rate in similarly aged individuals within Washington state.
A University of Washington study analyzes how a state's refundable Earned Income Tax Credit can lead to fewer reports of child neglect, by reducing the financial stress on families.
A team of marine scientists has confirmed that southern Africa’s most threatened endemic shark – the Critically Endangered shorttail nurse shark (Pseudoginglymostoma brevicaudatum) – has been found to occur in Mozambique; a finding that represents a range extension of more than 2,000 kilometers (1,242 miles).
Less than twenty years ago, most people diagnosed with advanced age-related macular degeneration (AMD) were destined to become legally blind. Today, advances in the diagnosis and treatment of AMD made possible by retina specialists allow many patients with advanced AMD to keep reading, driving and enjoying their independence.
As the pandemic continues, scientists are increasingly focused on developing methods to assist in decontaminating surfaces and spaces. In Review of Scientific Instruments, researchers report on experimental tools capable of presenting electromagnetic waves to an aerosol mixture with the capability to vary power, energy, and frequency of the electromagnetic exposure. The researchers seek to better characterize the threshold levels of microwave energy needed to inactivate aerosolized viral particles and reduce their ability to spread infection.
The positions of air inlets and outlets in confined spaces, such as elevators, greatly affect airborne virus transmission. In Physics of Fluids, researchers show air purifiers may actually increase the spread. They use ultraviolet radiation to kill viruses and other microbes, but they also circulate air, sucking it in and exhausting cleaned air. This adds to overall circulation.
A UVA physician’s software that monitors patients to predict clinical problems is helping COVID patients.
Blood draws are no fun.They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too.Oftentimes, doctors use blood samples to check for biomarkers of disease: antibodies that signal a viral or bacterial infection, such as SARS-CoV-2, the virus responsible for COVID-19, or cytokines indicative of inflammation seen in conditions such as rheumatoid arthritis and sepsis.
It's mid-January 2021, and the first gray whales from the eastern North Pacific population have started to arrive in the breeding lagoons in Baja California, Mexico.
Patients of Asian and black backgrounds suffered disproportionate rates of premature death from COVID-19, according to a study of 1,737 patients by Queen Mary University of London and Barts Health NHS Trust.
