The link between obesity and the risk of endometrial cancer has been well documented. A new study, however, shows that an even lower body mass index (BMI) than previously thought can signal an increased risk in Asian women with postmenopausal bleeding. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).

How common COVID-19 is among infants may depend on the degree of the pandemic virus circulating in a community.

Much has been rightfully made of the valiant work of doctors and nurses during the coronavirus pandemic. But what of infection preventionists (IP), whose job was to keep those workers and their facilities safe, and who many Americans do not even know exist?

A new mathematical model has been developed by QUT researchers to uncover land clearing when satellite imagery is obstructed by clouds.

By using a fluid mixing process instead of expensive, high-temperature fabrication methods, researchers may have demonstrated a pathway to producing flexible, printed solar cells on a cost effective, industrial scale.

A combination of factors makes a warming climate beneficial to rattlesnakes. The snakes are experts at thermoregulation, need few calories to survive, and would likely have more active time seasonally and during a given day.

Rutgers researchers have developed a machine learning model using a physics-based simulator and real-world meteorological data to better predict offshore wind power.

A new study shows that colleges students are experiencing significant grief reactions in response to the COVID-19 pandemic.

A University of Arkansas researcher and international colleagues found that employed individuals, on average, are 35.3% more likely to be infected with the flu virus.

A new study in the Journal of the American Heart Association shows that a breathing exercise known as Inspiratory Muscle Strength Training can reduce blood pressure in weeks, with benefits on par with daily exercise or medication.

Male jackdaws don't stick around to console their mate after a traumatic experience, new research shows.

A new analysis of 58 studies and 44305 patients published in Anaesthesia (a journal of the Association of Anaesthetists) shows that, contrary to some previous research, being male and increasing body mass index (BMI) are not associated with increased mortality in COVID-19 in patients admitted into intensive care (ICU).

The AIDS Clinical Trials Group (ACTG), the largest global HIV research network, today announced that findings from a sub-study of REPRIEVE (A5332/A5332s, an international clinical trial studying heart disease prevention in people living with HIV) have been published in the Journal of the American Medical Association Network Open. The study found that approximately half of study participants, who were considered by traditional measures to be at low-to-moderate risk of future heart disease, had atherosclerotic plaque in their coronary arteries.

Researchers at the University of Arizona believe the liver may hold the key to new, preventative Type 2 diabetes treatments.

Keep your checklists handy because the 62nd Supplement to the American Ornithological Society's Check-list of North American Birds, publishing today in Ornithology, includes numerous updates to the classification of the continent's bird species. A few highlights from this year's supplement include species splits for Mew Gull, Barred Owl, and Sedge Wren, among quite a few others; a transfer back to an old genus for Ruby-crowned Kinglet; and a revision of the linear sequence of passerine families.

Knowing the weight of a commodity provides a way to value goods in the marketplace. But did a self-regulating market even exist in the Bronze Age? And what can weight systems tell us? Researchers from Göttingen University investigated the dissemination of weight systems throughout Western Eurasia. Their simulation indicates that the interaction of merchants, even without intervention from institutions, is likely to explain the spread of Bronze Age technology to weigh goods.

Penn Engineers' "metallic wood" gets its useful properties and name from a key structural feature of its natural counterpart: porosity. As a lattice of nanoscale nickel struts, metallic wood is full of cell-sized pores that radically decrease its density without sacrificing strength. They have now solved a major problem preventing metallic wood from being manufactured at meaningful sizes: eliminating "inverted cracks," a kind of defect that has plagued similar materials for decades.

Article topics include the Great Unconformity of the Rocky Mountain region; new Ediacara-type fossils; the southern Cascade arc (California, USA); the European Alps and the Late Pleistocene glacial maximum; Permian-Triassic ammonoid mass extinction; permafrost thaw; the southern Rocky Mountains of Colorado (USA); "gargle dynamics"; invisible gold; and alluvial fan deposits in Valles Marineris, Mars.

Scientists and doctors at UCL Great Ormond Street Institute of Child Health (UCL GOS ICH) and Great Ormond Street Hospital (GOSH) have given hope of a gene therapy cure to children with a rare degenerative brain disorder called Dopamine Transporter Deficiency Syndrome (DTDS). The team have recreated and cured the disease using state-of-the-art laboratory and mouse models of the disease and will soon apply for a clinical trial of the therapy.

UCLA engineers have demonstrated successful integration of a novel semiconductor material into high-power computer chips to reduce heat on processors and improve their performance. The advance greatly increases energy efficiency in computers and enables heat removal beyond the best thermal-management devices currently available.
