There are substantial differences among low- and middle-income countries in the association between BMI and diabetes risk. Individual countries can optimize diabetes screening by tailoring guidelines to their specific population's risk threshold for BMI, age and gender. In some parts of the world, diabetes risk is greater at lower BMI thresholds and in younger ages than reflected in currently used cutoffs.

An observational study of more than 70,000 people in 302 UK hospitals finds that one in two people hospitalized with COVID-19 developed at least one complication. The new study, published in The Lancet, is the first to systematically assess a range of in-hospital complications, and their associations with age, sex and ethnicity, and their outcomes for the patients.

Using anonymized medical records from a national registry, UC San Diego researchers confirm earlier findings that statins may substantially minimize adverse outcomes from SARS-CoV-2 infection.

A "tantalizing" principle borrowed from nature turns harmful methane into useful methanol at room temperature. With their latest study, U.S. and Belgian scientists have brought this process an important step closer to realization.

Harvard researchers have shown that jumping spiders are able to tell the difference between animate objects and inanimate objects -- an ability previously known only in vertebrates, including humans.

In a new study, published in the journal Nature, researchers looked at samples from rocks spanning the last three billion years and found evidence of a dramatic change in how the carbon cycle functioned about 400 million years ago, when plants started to colonise land.

In this study using a simulated cohort, TVUS endometrial thickness screening missed over four times more cases of endometrial cancer among Black women versus White women owing to the greater prevalence of fibroids and non-endometrioid histology type that occurs among Black women.

The RegenMed Development Organization releases the results of a national survey of regenerative medicine biomanufacturing knowledge, skills, and abilities needed for successful employment in the regenerative medicine field.

A national study published in the Journal of Pediatrics found that Emergency Department (ED) visits by youth for self-harm were nearly 40 percent higher in rural areas compared to urban settings. Strikingly, ED visits by youth for self-inflicted firearm injuries were three times more common in rural areas.

A new national study published in Public Health Nutrition on July 15 found that Americans experiencing food insufficiency were three times as likely to lack mental health support during the COVID-19 pandemic than those not experiencing food insufficiency.

Scientists on the hunt for an unconventional kind of superconductor have produced the most compelling evidence to date that they've found one. In a pair of papers published in Science and Nature Communications, researchers at the University of Maryland's Quantum Materials Center and colleagues have shown that uranium ditelluride displays many of the hallmarks of a topological superconductor--a material that may unlock new ways to build quantum computers and other futuristic devices.

A new study shows that it is possible to use mechanical force to deliberately alter chemical reactions and increase chemical selectivity - a grand challenge of the field.

A collaborative team from the Terasaki Institute for Biomedical Innovation has designed a wearable strain sensing device that can effectively detect a wide range of strains.

A new tool developed by a University of Minnesota research team allows farmers to create a budget balance sheet of any nitrogen reduction plans and see the economic and environmental cost, return and margins, all customized to fields under their management.

The American Academy of Sleep Medicine (AASM) and Sleep Research Society (SRS) have published evidence-based guiding principles to help employers determine optimal work shift durations for their workplace. With a process that assesses risks, considers countermeasures, and institutes an informed approach to determine and evaluate shift durations, employers can make shift duration decisions that manage fatigue-related risks while also maintaining high productivity and safety.

Researchers from Skoltech have found a way to help computer vision algorithms process satellite images of the Earth more accurately, even with minimal data for training. This will make various remote sensing tasks easier for machines and, ultimately, the people who use their data.

Burnout. It is a syndrome that is said to afflict humans who feel chronic stress. But after conducting a novel study using trail cameras showing the interactions between white-tailed deer fawns and predators, a Penn State researcher suggests that prey animals feel it, too.

Earth's climate was relatively stable for a long period of time. For three billion years, temperatures were mostly warm and carbon dioxide levels high - until a shift occurred about 400 million years ago. A new study suggests that the change at this time was accompanied by a fundamental alteration to the carbon-silicon cycle.

Corn growers can choose from a wide array of products to make the most of their crop, but the latest could bring seaweed extract to a field near you. The marine product is just one class in a growing market of crop biostimulants marketed for corn. Biostimulants benefit crops and soil, but the dizzying array of products has farmers confused, according to Fred Below, corn and soybean researcher at the University of Illinois.

A new study identified groups that are more likely to be placed in extended solitary management (ESM). The study found that individuals sent to ESM differed considerably from the rest of the prison population in terms of mental health, education, language, race/ethnicity, and age.
