PHILADELPHIA – For more than two decades, the Annenberg Public Policy Center has tracked the ways in which news organizations erroneously link the year-end holiday season with suicide, perpetuating the false holiday-suicide myth. But as years of national data show, the winter holiday months usually have low average daily suicide rates, with December the lowest of all. In our new media analysis, we find that of the newspaper stories during the 2022-23 holiday season that explicitly connected the holidays with suicide, 60% correctly debunked the myth while 40% incorrectly supported it. But it’s not just the media that ...

What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants. That’s according to a study published in Science Advances, co-authored by Don Baker, a professor in McGill University’s Department of Earth and Planetary Sciences. The research team delved into volcanic eruptions of the Deccan Traps—a ...

To address this rise, the Korea Occupational Safety and Health Agency has been providing virtual reality (VR)-based construction safety content to daily workers as part of their educational training initiatives. Nevertheless, ...

Nanoparticles are super tiny―as small as one nanometer, or one billionth of a meter―and are of keen interest to materials scientists for their unique physical and chemical properties. They cannot be detected by the naked eye and require a highly specialized electron microscope to be seen. In fact, advancements in imaging technologies through the 1990s and early 2000s are what made the field of nanoscience possible, says Anne Bentley, a faculty member in the Department of Chemistry at Lewis & Clark College in Portland, Oregon. “I ...

HOUSTON – (Dec. 4th, 2023) – The properties that make materials like semiconductors so sought after result from the way their atoms are connected, and insight into these atomic configurations can help scientists design new materials or use existing materials in new, unforeseen ways. Rice University materials scientist Yimo Han and collaborators mapped out the structural features of a 2D ferroelectric material made of tin and selenium atoms, showing how domains ⎯ areas of the ...

The skin is the largest organ in the human body and plays an important role in maintaining homeostasis as well as protecting the body from the outside environment. Skin diseases can be life-threatening or heavily impair patients’ quality of life. Urticaria (also called “hives”) is common, affecting at least one in five people in their lifetime, and can persist for years or even decades. Many skin diseases are unique to humans, and their pathogenesis often remains unclear due to the lack of an appropriate experimental animal model and limited clinical data. One such human-specific disease is chronic spontaneous urticaria (CSU), which is characterized by the ...

A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein’s classical concept of spacetime is announced today in two papers published simultaneously by UCL (University College London) physicists. Modern physics is founded upon two pillars: quantum theory on the one hand, which governs the smallest particles in the universe, and Einstein’s theory of general relativity on the other, which explains gravity through the bending of spacetime. But these two theories are in contradiction with each other and a reconciliation ...

Nearly 1,000 birds were killed Oct. 4-5 when they collided with an illuminated glass building in Chicago. Though mass fatalities of this magnitude are rare, light pollution poses a serious – and growing – threat to migrating birds.   In the largest study of its kind, published in Nature Communications, scientists used weather radar data to map bird stopover density in the United States and found that artificial light is a top indicator of where birds will land. City lights lure birds into what can be an ecological trap, said lead author Kyle Horton, an assistant professor ...

Decades after blood pressure-related pregnancy complications, Hispanic/Latina women can have changes in heart structure and function Findings highlight importance of early monitoring and management of hypertension during and after pregnancy Hispanic/Latina women with a history of hypertensive disorders of pregnancy (HDP) – conditions marked by high blood pressure during pregnancy – are more likely to have abnormalities in their heart structure and function decades later when compared with women without a history of HDP, according to a National Institutes ...

Lesbian, gay, and bisexual (LGB) adolescents and young adult cancer survivors in the United States are more likely to report experiencing chronic health conditions than their heterosexual peers with a history of cancer as well as their LGB peers without a past cancer diagnosis. The findings come from a survey-based study published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. Previous studies have indicated that minority sexual orientation and gender identity populations have higher prevalence rates of many chronic conditions—including heart disease, ...

BETHESDA, Maryland (December 4, 2023) — Societal issues — including the growth in ultra-high-cost treatments, the epidemic of mental health and substance use disorders, climate change, and the rise of artificial intelligence (AI)— could alter how health systems serve their communities within five years, according to the latest annual ASHP/ASHP Foundation Pharmacy Forecast Report. The 2024 Pharmacy Forecast, released today at the ASHP Midyear Clinical Meeting & Exhibition, drew ...

Polar bears are icons of the Arctic, elusive and vulnerable. Detailed monitoring of their populations is crucial for their conservation — but because polar bears are so difficult to find, we are missing critical data about population size and how well connected those populations are. Scientists have now developed a new tool to help: DNA analysis using skin cells shed in the bears’ footprints in the snow. “It is particularly challenging, expensive, and time-consuming to find polar bears in the Arctic, let alone count them and understand how they are coping with climate change,” said Dr Melanie Lancaster of the World Wide Fund for Nature Global ...

Often referred to as the ‘dream batteries’, all-solid-state batteries are the next generation of batteries that many battery manufacturers are competing to bring to market. Unlike lithium-ion batteries, which use a liquid electrolyte, all components, including the electrolyte, anode, and cathode, are solid, reducing the risk of explosion, and are in high demand in markets ranging from automobiles to energy storage systems (ESS). However, devices that maintain the high pressure (tens of MPa) required for stable operation of all-solid-state batteries have problems that reduce the battery performance, such as energy density and capacity, ...

In a world where plant-based lifestyles are on the rise, the power of foods such as broccoli, celery, and tofu, which are rich in flavonoids, is becoming clearer. Flavonoids are phenolic compounds produced by plants that are essential for plant development and defense and have long been said to have therapeutic and preventive effects against cancer and heart disease. However, the exact process of how our bodies metabolize flavonoids remains unclear. An international team of researchers led by visiting researcher Tsutomu Shimada and Professor Shigeo ...

How do emergency department staff determine whether older adults who have fallen need imaging? A new decision rule will help emergency department physicians determine which older adults need imaging for head injuries, describes new research in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.230634. With aging populations, emergency departments are managing an increasing number of older adults who fall; falling on level ground, like in one's house, is a common cause of a brain bleed. Computed tomography (CT) of the head is commonly used to assess patients who have fallen, but sending every patient who has fallen ...

To improve primary care, Canada can learn from Organisation for Economic Co-operation and Development (OECD) countries with high rates of patients attached to primary care clinicians, write authors in an analysis in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.221824. It is well known in Canada that there is a crisis in primary care, with about 17% of people reporting that they were without a regular primary care clinician before the COVID-19 pandemic. ...

EMBARGOED UNTIL MONDAY, DECEMBER 4, 2023 AT 12:01 a.m. EST The holiday season is a time for joy and celebration but many Americans admit the endless flurry of activities make it difficult to eat healthy, exercise and get adequate rest, according to a new survey from The Ohio State University Wexner Medical Center. Two-thirds of those surveyed said they overindulge in food, nearly 45% said they take a break from exercise and more than half report feeling tired and have less time for themselves. Plus, a third admit they drink more alcohol during the holidays. “Holiday travel, activities with friends and ...

SYDNEY, Dec. 4, 2023 – An estimated quarter of adults and two-thirds of children have strong fears around needles, according to the U.S. Centers for Disease Control and Prevention. Yet, public health depends on people being willing to receive vaccines, which are often administered by a jab. Darcy Dunn-Lawless, a doctoral student at the University of Oxford’s Institute of Biomedical Engineering, is investigating the potential of a painless, needle-free vaccine delivery by ultrasound. He will share the recent advancements in this promising technique as part of Acoustics 2023 Sydney, running ...

University of Queensland-led research shows being overweight can impair the body’s antibody response to SARS-CoV-2 infection but not to the protection offered by vaccination. Research lead, School of Chemistry and Molecular Biosciences PhD candidate Marcus Tong, said the finding built on the team’s existing research on how COVID-19 affects people who are overweight. “We’ve previously shown that being overweight – not just being obese – increases the severity of SARS-CoV-2,” Mr Tong said. “But this ...

The recent publication in Science by Mogila, Tamulaitiene et al. represents a continuation of the successful scientific research conducted by Gintautas Tamulaitis’ group. In this study, the Vilnius University researchers using bioinformatic analysis, biochemical, and structural studies characterized a novel family of effector proteins, named Cami1. They showed that when a virus attacks a bacterium, CRISPR-Cas10 signaling molecules activate Cami1 - a ribosome-dependent ribonuclease. “Activated Cami1 cleaves mRNAs that are involved in protein synthesis, thereby inhibiting cell growth. This allows the bacterium to save resources and prevents production ...
