Treating the COVID-19 'infodemic' as an epidemic
A group of science communication researchers proposes to treat the Covid-19 misinformation "infodemic" with the same methods used to halt epidemics: real-time surveillance, accurate diagnosis, and rapid response.

Study: Drivers with shift work sleep disorder 3x more likely to be in crash
People who work nontraditional work hours, such as 11 p.m.-7 p.m., or the "graveyard" shift, are more likely than people with traditional daytime work schedules to develop a chronic medical condition -- shift work sleep disorder -- that disrupts their sleep. According to researchers at the University of Missouri, people who develop this condition are also three times more likely to be involved in a vehicle accident.

Ticking upward: MU researcher studies rise of tick-borne diseases in Midwest
When Ram Raghavan heard from a former colleague at the Centers for Disease Control and Prevention that a 7-year-old girl had died from Rocky Mountain spotted fever as the result of a tick bite, he thought of his own daughter, also 7 years old at the time, and the potentially fatal danger posed to vulnerable populations by tick-borne diseases.

HSS researchers find duloxetine may reduce opioid use after total knee replacement
In a study conducted by researchers at HSS, cumulative opioid use was reduced by 30% in a patient group that received duloxetine after total knee arthroplasty (TKA) compared with patients who received placebo. Patients who received duloxetine also reported higher pain management satisfaction and less pain interference with mood, walking, normal sleep, and work activities. These findings were presented at the 2021 Spring American Society of Regional Anesthesia and Pain Medicine (ASRA) Annual Meeting.

New evidence for electron's dual nature found in a quantum spin liquid
New experiments conducted at Princeton University provide evidence for a decades-old theory that, in the quantum regime, an electron behaves as if it is made of two particles: one particle that carries its negative charge and the other that gives it a magnet-like property called spin. The team detected evidence for this theory in materials called quantum spin liquids.

Songbird neurons for advanced cognition mirror the physiology of mammalian counterparts
University of Massachusetts Amherst neuroscientists examining genetically identified neurons in a songbird's forebrain discovered a remarkable landscape of physiology, auditory coding and network roles that mirrored those in the brains of mammals.

Triple-negative breast cancer more deadly for African American women
New research from Washington University School of Medicine in St. Louis shows that non-Hispanic African American women with triple-negative breast cancer have lower survival rates than non-Hispanic white women with this type of breast cancer. The study demonstrates the need for additional research to address disparities in cancer care and understand whether tumor biology or nonbiological reasons such as systemic racism -- or a combination of such factors -- may be driving these disparities.

Social media networking doesn't 'level the playing field' for women physicians
The same biases that exist for women physicians in person also exist in social media networking, a new Northwestern Medicine study reports. What's more, a previous study found women physicians are twice as likely to face sexual harassment online than men. The new study's findings speak to gender-equity issues for professional women outside medical field.

The emergence of cooperation
Cooperation plays a crucial role in evolution. A team of scientists around Laura Schmid from the Chatterjee group at the Institute of Science and Technology (IST) Austria has now created a new model that shows how different kinds of cooperative strategies among humans develop. Using their unified framework, they show how an individual's experience and the reputation of others influence the emergence of successful cooperation.

Carbon emissions from dams considerably underestimated so far
Among other things, dams serve as reservoirs for drinking water, agricultural irrigation, or the operation of hydropower plants. Until now, it had been assumed that dams act as net carbon stores. Researchers from the Helmholtz Centre of Environmental Research (UFZ) together with Spanish scientists from the Catalan Institute for Water Research (ICRA) and the University of Barcelona showed that dams release twice as much carbon as they store. The study has been published in Nature Geosciences.
