A team of fusion researchers at the Department of Energy’s Oak Ridge National Laboratory used datasets from measurements on the Joint European Torus, or JET, tokamak to model an improved method for quantifying the amount of plasma-radiated power during a disruption of normal operations.

Impurities in the plasmas in tokamaks can reduce performance. These impurities are from interactions between the hot plasma and tungsten tokamak walls. This experiment found that tokamak magnetic fields that rotate clockwise direction can remove these impurities. This is the opposite direction from normal and the same direction the plasma current moves.

A layer of “hot,” electrically conductive ice could be responsible for generating the magnetic fields of ice giant planets like Uranus and Neptune. New work from Carnegie and the University of Chicago’s Center for Advanced Radiation Sources reveals the conditions under which two such superionic ices form.

Facial recognition, body cameras and other digital technologies are increasingly used by police departments, municipalities and even gated communities, but these tools manufactured by private companies raise the specter of unchecked surveillance, a University of California, Davis, researcher, suggests.
A new study captures the scope of the COVID-19 pandemic's impact on public health: Many public health workers have been redeployed to COVID-related duties, leaving other critical public health issues with reduced or suspended services. That means investigation of other communicable diseases, food-related illness, public-health surveillance, chronic diseases and other critical services have suffered.

A new project backed by Cornell University and the USDA will explore the economic benefits of grazing sheep under industrial-scale solar arrays.
Presented at the 2021 Frontiers in Optics + Laser Science Conference (FiO LS), researchers from Boston University have developed a novel wavelength-tunable, silicon photon-pair source that incorporates both active photonic devices and feedback control circuits on a single CMOS chip.

In a new USC study on the health effects of a low-calorie diet that mimics fasting in the body, researchers found regular five-day cycles of the diet in mice seemed to counteract the detrimental effects of their usual high-fat, high-calorie diet. The study, published today in Nature Metabolism, analyzed the diet, health and lifespan of three different groups of mice over two years.

In a new study, Gary Moore and his research group explore different approaches to catalysis, a chemical process that plays an essential role in biological reactions, as well as many industrial applications. Chemical catalysts have been used in a variety of human applications, ranging from pharmaceutical development to biodegradable plastics and environmentally safe fertilizers. They may also advance the development of green energy solutions to address the climate crisis, an area Moore’s group has actively pursued.

Vaccination uptake rates of the HPV vaccine remain low despite the fact that the effectiveness of the vaccine has been established for over a decade. A new article based on research conducted at the University of Illinois addresses how the gap in vaccinations can be traced to misinformation regarding the risks of the vaccine. For their study, the research team developed a series of models to identify and examine true and false HPV vaccine–related information on Twitter, finding that misinformation strongly favors negative-leaning, “loss framed” messaging.
