WASHINGTON, May 6, 2025 – The triangle is a small instrument made of a metal rod bent into a triangle shape that is open at one corner. While small, its sound is distinct, with multiple overtones and nonharmonic resonance. But what causes the surprisingly powerful sound? “The triangle instrument produces enchanting and beautiful tones, raising deep and profound questions about the connection between music and physics,” author Risako Tanigawa said. “Optical sound measurement has only been applied to limited subjects until now. By observing the sound field of a triangle for ...

WASHINGTON, May 6, 2025 – From bird flocking to fish schooling, many biological systems exhibit some type of collective motion, often to improve performance and conserve energy. Compared to other swimmers, manta rays are particularly efficient, and their large aspect ratio is useful for creating large lift compared to drag. These properties make their collective motion especially relevant to complex underwater operations. To understand how their group dynamics affect their propulsion, researchers from Northwestern Polytechnical University (NPU) and the Ningbo Institute of NPU, in China, modeled the motions of groups of manta rays, which they present in Physics of Fluids, by AIP ...

About The Study: In this study using data from retrospectively reported pregnancies from 3 longitudinal cohorts, all sexual minority groups had increased abortion use compared with completely heterosexual participants, and abortion use was heterogeneous; given the higher use of abortion among sexual minority populations, they are more likely to be disproportionately impacted by the narrowing of abortion access in the U.S. after the Supreme Court Dobbs decision. Future research is needed to understand the pathways that contribute to the unique abortion care needs of sexual minority ...

About The Study: In this cohort study of sexual and gender minority (SGM) young adults assigned male at birth, exposure to sexual orientation and gender identity change efforts (SOGICE) was associated with adverse cardiovascular health indicators, including elevated diastolic blood pressure and systolic blood pressure, increased systemic inflammation, and higher odds of self-reported hypertension or high blood pressure. These findings underscore the need for public health and policy interventions to enforce ...

As researchers make progress in understanding how Alzheimer’s disease develops, there are growing opportunities for healthy research participants to learn their risk of developing Alzheimer’s disease dementia in the future. While many organizations often advocate for investigators to share risk estimates with individual participants, there are ethical concerns around doing so, given that there are no medical interventions to change that risk. A new study from Washington University School of Medicine in St. Louis examines the choices such healthy research volunteers make ...

In a new National Institutes of Health-funded study led by scientists at the Wilmer Eye Institute, Johns Hopkins Medicine researchers say they have determined that low blood sugar, or hypoglycemia, may promote a breakdown of the blood-retinal barrier, an important boundary that regulates the flow of nutrients, waste and water in and out of the retina. The research, which investigated the phenomenon in diabetic mice, provides insights into the origin of diabetic retinopathy, specifically in patients with episodes of hypoglycemia. Diabetic retinopathy, a severe complication of both type 1 and type 2 diabetes, can cause permanent vision damage ...

Highlights: Fermenting organic matter can produce biogas, which includes methane, and suggests a sustainable alternative to fossil fuels. Alfalfa, often used as feed, produces biogas after fermentation. Adding fruit waste and Lactobacillus acidophilus to alfalfa boosts biogas production and improves fermentation, according to a new study. The process points to a useful way to dispose of fruit waste, produce energy and enhance agricultural feed. Washington, D.C.—Alfalfa is more than a protein-rich feed for livestock; it may also be an excellent source of biogas. This mixture of methane and other gases is produced when plants (or ...

Up to 250,000 deaths from poor air quality could be prevented annually in central and western Europe by 2050 if greenhouse gas emissions are drastically reduced, say researchers. A study by atmospheric scientists at the University of Leeds has revealed that the number of deaths could be significantly reduced, but only if there is a strong focus on reducing greenhouse gases and air pollutants. As well as finding that strong climate mitigation would result in large reductions in air quality mortality, the team has also discovered that it reduces the inequitable burden of air quality mortality in more deprived parts of Europe. Their findings are published today (6 May) in the journal Earth’s ...

Satellite communication is an indispensable part of sixth generation of mobile communication systems (6G) given its global coverage and long-distance propagation. Energy consumption and channel acquisition are two critical issues in satellite communication systems. On the one hand, with the rapidly increasing energy wastage in wireless systems, green communication technology has attracted extensive attentions and energy efficiency (EE) becomes the key performance indicator in the transmission scheme design of satellite communications. On the other hand, channel state information (CSI) is well required in designing the beamforming, but it is infeasible for gateway ...

BALTIMORE, May 6, 2025— A newly published trial from Kennedy Krieger Institute reveals a promising path forward for infants showing early signs of social communication delays. The study found that targeted coaching for caregivers of infants as young as 8 months significantly enhances babies’ communication and cognitive development. Caregivers in the trial received 16 in-home sessions with a trained developmental psychologist. Strategies included narrating an infant’s actions, such as saying “you rolled the ball,” and choosing toys that support language, attention, and engagement. This is one of the ...

“Hic sunt leones,” remarks Stefano Liberati, one of the authors of the paper and director of IFPU. The phrase refers to the hypothetical singularity predicted at the center of standard black holes — those described by solutions to Einstein’s field equations. To understand what this means, a brief historical recap is helpful. In 1915, Einstein published his seminal work on general relativity. Just a year later, German physicist Karl Schwarzschild found an exact solution to those equations, which implied the existence of extreme objects now known as black holes. These are objects with mass so concentrated that nothing — not even light — ...

Growing communities and extensive agriculture throughout the Western United States rely on meltwater that spills out of snow-capped mountains every spring. The models for predicting the amount of this streamflow available each year have long assumed that a small fraction of snowmelt each year enters shallow soil, with the remainder rapidly exiting in rivers and creeks. New research from University of Utah hydrologists, however, suggests that streamflow generation is much more complicated. Most spring runoff heading to reservoirs is actually several years old, indicating ...
