OTHELLO, Wash. — Keeping queen bees chilled in indoor refrigeration units can make the practice of “queen banking” — storing excess queens in the spring to supplement hives in the fall — more stable and less labor-intensive, a Washington State University study found. It may also help strengthen honey bee survival in the face of a changing climate. In a paper published in the Journal of Apicultural Research, researchers compared queen banks stored in refrigerated units to those stored in the conventional ...

Research Highlights: Black women of childbearing age were more than twice as likely to have uncontrolled blood pressure than white women of similar age, putting them at an increased risk of pregnancy-related complications. This disparity in high blood pressure persisted after adjusting for social determinants of health, health factors and modifiable health behaviors. Food insecurity — lack of access to adequate healthy food — one of the social factors that may affect high blood pressure risk, was higher among Hispanic and Black women compared with white women.  The research is featured in a special Go Red for Women issue of the Journal of the American Heart Association focused ...

Peer-reviewed / Mendelian Randomization / People An earlier first birth, a higher number of live births, and starting periods at a younger age are all linked to a higher risk of cardiovascular problems in women, according to new research. The study, led by Imperial College London researchers, provides evidence for a causal relationship between sex-specific factors and cardiovascular disease in women, and identifies potential ways to mediate this increased risk. The study is the most comprehensive analysis to date of reproductive factors specific to women and their links ...

Mutations of the gene encoding dystrophins have long been known to cause the debilitating muscle-wasting disease DMD, which affects one in every 5,000 boys born. People with the condition will usually only live into their 20s or 30s. Now, a study, led by the University of Portsmouth, has found that the same gene has a role in oncology. A team of international researchers analysed a broad spectrum of malignant tissues, including from breast, ovarian, and gastrointestinal cancer patients.  The DMD gene expression was reduced in 80 per cent of these tumours. This low expression of dystrophins was associated with a more advanced stage of cancer and reduced ...

Using a new dataset, Rafael Prieto-Curiel of the Complexity Science Hub and colleagues analyzed the coordinates and surface of 183 million buildings in nearly 6,000 cities across all 52 countries in Africa. With their model, they quantify the shape of cities. Thus, they show that if a city's population doubles, the energy demand associated with commuting triples. These results clearly show how important it will be to plan fast-growing cities in a sustainable way. “Our model allows us to estimate African cities’ transport requirements and energy needs with a never before seen accuracy,” Prieto-Curiel, researcher at the Complexity ...

MINNEAPOLIS – Black people are receiving medications for dementia less often than white people, according to a preliminary study released today, February 26, 2023, that will be presented at the American Academy of Neurology’s 75th Annual Meeting being held in person in Boston and live online from April 22-27, 2023. “Previous research has shown that due to racial disparities, people with dementia do not always receive the same access to medications that may be beneficial in nursing homes and hospitals,” said Alice Hawkins, MD, of Mount Sinai in New York, New York, and a member of the ...

Three years into a five-year pledge to completely phase out lead shot in UK game hunting, a Cambridge study finds that 94% of pheasants on sale for human consumption were killed using lead. The pledge, made in 2020 by nine major UK game shooting and rural organisations, aims to protect the natural environment and ensure a safer supply of game meat for consumers. Lead is toxic even in very small concentrations, and discarded shot from hunting poisons and kills tens of thousands of the UK’s wild birds each year. A Cambridge-led team of 17 volunteers bought whole pheasants from butchers, game ...

Octopus arms coordinate nearly infinite degrees of freedom to perform complex movements such as reaching, grasping, fetching, crawling, and swimming. How these animals achieve such a wide range of activities remains a source of mystery, amazement, and inspiration. Part of the challenge comes from the intricate organization and biomechanics of the internal muscles. This problem was tackled in a multidisciplinary project led by Prashant Mehta and Mattia Gazzola, professors of mechanical science & engineering at the University of Illinois ...

As the mental health crisis continues across the nation, many people struggle to find the care they need. Health insurers publish directories of mental health providers to help consumers obtain care; however, inaccurate directories and a shortage of providers within many insurance networks can make finding covered mental health services challenging. The U.S. federal government and those of many states have put regulations in place to ensure provider directory accuracy, with California having some of the most stringent rules. However, research on the accuracy of mental health care provider directories has been limited. Simon Haeder, PhD, associate ...

UNIVERSITY PARK, Pa. — Workers tasked with moving products in the immense U.S. food system are at a high risk of serious injury, according to a new Penn State-led study, and pandemic-caused, supply-chain problems have worsened the situation, researchers suggest. The modern food supply chain presents unique hazards to employees that result in higher rates of death and injury when compared to most other industries, noted lead researcher Judd Michael, Penn State professor of agricultural and biological engineering. ...

BOSTON – As legislation in multiple states eases former restrictions around medical and recreational cannabis in the United States, an increasing proportion of the population reports use of the drug. Between 2016 and 2018, more than 22 percent of Massachusetts residents reported any prior cannabis use for medical or recreational reasons. However, little is known about cannabis use in patients who undergo surgery or interventional procedures, where cannabis use has important additional clinical implications. In a new study published in The Lancet’s eClinical Medicine, researchers led ...

UNIVERSITY PARK, Pa. — Perovskites, a family of materials with unique electric properties, show promise for use in a variety fields, including next-generation solar cells. A Penn State-led team of scientists created a new process to fabricate large perovskite devices that is more cost- and time-effective than previously possible and that they said may accelerate future materials discovery. “This method we developed allows us to easily create very large bulk samples within several minutes, rather than days or weeks using traditional methods,” said Luyao Zheng, a postdoctoral researcher in the Department of Materials Science at Penn State and lead author on the ...

Excess weight or obesity boosts risk of death by anywhere from 22% to 91%—significantly more than previously believed—while the mortality risk of being slightly underweight has likely been overestimated, according to new CU Boulder research. The findings, published Feb. 9 in the journal Population Studies, counter prevailing wisdom that excess weight boosts mortality risk only in extreme cases.  The statistical analysis of nearly 18,000 people also shines a light on the pitfalls of using ...

Ancient climates can help us understand the past, but also the future. 23 million years ago, in a time called the Miocene Epoch, Connecticut was around five to six degrees warmer than today and located roughly where Long Island is now. By the end of the Miocene, around five million years ago the earth had gradually cooled, Antarctica was glaciated, and there was some Arctic ice as well. This cooling scenario moved in the opposite direction of today’s changing climate. One difference UConn Department of Earth Sciences Assistant Professor in Residence Tammo Reichgelt points out is that in the past, these changes happened gradually, spaced ...

Substance use disorder (SUD) is an extremely difficult disorder to overcome, and many individuals with SUD return to regular use after repeated attempts to quit. A return to regular drug use can be caused by the body’s physical dependence on the drug as well as experiences associated with prior drug use. Exactly how these drug associations are formed in the brain and how they trigger a return to drug use remain unclear. “Individuals make long-lasting associations between the euphoric experience of the drug and the people, places and things associated with drug use,” said Christopher Cowan, Ph.D. professor in the Department ...

LEXINGTON, Ky. (Feb. 24, 2023) — A recent University of Kentucky Markey Cancer Center study suggests a new radiopharmaceutical compound may be a viable treatment option for patients with advanced cervical cancer. The study, led by UK Markey Cancer Center radiation oncologist Charles Kunos, M.D., and published in Frontiers in Oncology, validates that the radioactive drug 212Pb-DOTAM-GRPR1 may be useful in the treatment of persistent, recurrent, or metastatic cervical cancer. Radiopharmaceuticals are expected to play ...

For two decades, scientists have observed an elongated object named X7 near the supermassive black hole at the center of the Milky Way and wondered what it was. Was it pulled off a larger structure nearby? Was its unusual form the result of stellar winds or was it shaped by jets of particles from the black hole? Now, having examined the evolution of X7 using 20 years of data gathered by the Galactic Center Orbit Inintiative, astronomers from the UCLA Galactic Center Group and the Keck Observatory propose that it could be a cloud of dust and gas that was ejected during the collision of two stars. Over time, they report, X7 has stretched, and it is being pulled apart ...

CHAPEL HILL, N.C. – Our bodies are made up of 60,000 miles of complex pipes that play a vital role in transporting nutrients throughout our bodies, performing waste disposal, and supplying our organs with fresh oxygen and blood. Vascular malformations (VMs) are a group of rare genetic disorders that causes an abnormal formation of veins, arteries, capillaries, or lymphatic vessels at birth. VMs can interfere with the duties of our precious pipes by causing blockages, poor drainage, and the formation of cysts and tangles. To address a need for further study, William Polacheck, PhD, an assistant professor at the ...

Philadelphia, February 24, 2023—Researchers at Children’s Hospital of Philadelphia (CHOP) have identified variants of a chaperone molecule that optimizes the binding and presentation of foreign antigens across the human population, which could open the door to numerous applications where robust presentation to the immune system is important, including cell therapy and immunization. The findings were published today in Science Advances.  Class I major histocompatibility complex (MHC-I) proteins are ...

Antarctic bottom water (AABW) covers more than two-thirds of the global ocean bottom, and its formation has recently decreased. However, its long-term variability has not been well understood. Researchers led by Prof. DENG Chenglong from the Institute of Geology and Geophysics (IGG) of the Chinese Academy of Sciences (CAS) and their collaborators have reconstructed AABW history back to approximately 4.7 million years ago (mya). They found that AABW has collapsed several times and such collapses might have induced moisture transport to fuel the Northern Hemisphere ...
