CLEVELAND, Ohio (August 13, 2025)—Adults aged 65 years and older are becoming the fastest-growing demographic, yet, the sexual health of older women is often understudied and untreated. A new study demonstrates their rate of sexual problems is similar to that of midlife women, although they are less likely to report distress related to their sexual problems. Results of the study are published online today in Menopause, the journal of The Menopause Society. Although sexual activity declines with age, sexual health remains relevant throughout life ...

The need for biodegradable packaging material has never been higher. Currently, most packaging is "single use" and is made with plastic materials, derived from nonrenewable sources like crude oil that take hundreds of years to decompose in the environment. On top of this, only 9% of plastic is recycled. This has resulted in the formation of floating piles of plastic garbage in the ocean, called the "Great Pacific Garbage Patch." But maybe even more concerning is the discovery of micro- and nano-plastics in the environment. Research has found that plastic breaks down into tiny ...

An international study surveying people in a dozen countries found that when it comes to making complex decisions, people all over the world tend to reflect on their own, rather than seek advice. Researchers from the University of Waterloo led the new study that surveyed more than 3,500 people from megacities to small Indigenous communities in the Amazon rainforest to learn how they make decisions. This work is the broadest test of decision-style preferences across cultures to date. The researchers ...

Gait analysis and pain measures show that subtly adjusting the angle of the foot during walking may reduce knee pain caused by osteoarthritis. This approach may also slow progression of the condition, an uncurable disease in which the cartilage cushion inside a joint breaks down. Led by a team of researchers at NYU Langone Health, the University of Utah, and Stanford University, a new study explored whether changing the way patients position their feet when walking could lessen extra loading — stress on the joint during motion — and help treat the disease. For ...

There seem to be reciprocal links between certain groups of gut bacteria and the risk of insomnia, suggests a Mendelian randomisation study, published in the open access journal General Psychiatry. Certain types of bacteria seem to boost or lower the risk of the sleep disorder while insomnia itself seems to alter the abundance of certain types of bacteria, the findings indicate. Several studies have explored the effects of the gut microbiome on various sleep characteristics, but it’s not yet clear how different groups ...

Taste and price, rather than calorie content, seem to be the key considerations for those ordering takeaways online, despite calorie labelling legislation designed to help consumers make healthier food choices, suggests an analysis of survey responses, published in the open access journal BMJ Nutrition Prevention & Health. These orders tend to be favoured by younger people and those living with obesity, the responses indicate. And the limited impact of calorie labelling, despite relatively high awareness of the regulations, suggests that additional strategies are needed, say the researchers. Takeaways are ...

Patients are still more likely to trust doctors and consider them more professional when they wear white coats, although women doctors in this attire are often misidentified as nurses or medical assistants, finds a review of the available research on the topic, published in the open access journal BMJ Open. But patient preferences for doctors’ attire seem to be strongly influenced by clinical context and medical specialty, with a growing acceptance of scrubs, especially in emergency or high-risk settings, the findings indicate. In the 19th century, doctors primarily wore black, because medical encounters were viewed as serious and formal occasions. ...

The Lancet Gastroenterology & Hepatology: Routine AI assistance may lead to loss of skills in health professionals who perform colonoscopies, study suggests   An observational study of over 1,400 colonoscopies found the rate at which experienced health professionals detect precancerous growths in the colon in non-AI assisted colonoscopies decreased by 20% (from 28.4% to 22.4%) several months after the routine introduction of AI. Several studies have suggested that AI assistance may help doctors identify some cancers, but this is the first study to suggest the implementation of AI could lead to a reduction in the ability of ...

Overweight patients waiting for operations could safely use a particular type of weight-loss treatment to reduce the risk of surgical complications linked to their obesity, a new study reveals.  The study highlights glucagon-like peptide-1 receptor agonists (GLP-1 RAs) as a promising medication given before surgery that help control blood sugar and support weight loss - potentially improving surgical outcomes and reducing healthcare burdens associated with obesity.   However, the researchers stress an urgent need for high-quality randomised trials to validate these findings, assess cost-effectiveness, and guide implementation of the drug ...

Nearly a quarter of people over the age of 40 experience painful osteoarthritis, making it a leading cause of disability in adults. Osteoarthritis degrades joint-cushioning cartilage, and there is currently no way of reversing this damage: the only option is to manage pain with medication, and eventually, joint replacement.   Researchers from the University of Utah, New York University and Stanford University are now demonstrating the potential for another option: gait retraining.  By making a small adjustment to the angle of their foot while walking, participants in a year-long randomized control trial ...

Mental health services must urgently increase investment in lifestyle interventions to improve care and help close the 15-year life expectancy gap faced by people with mental illness, a new Lancet Psychiatry Commission report warns.   Lifestyle interventions targeting physical activity, nutrition, sleep and smoking are key to mental health care, not optional extras, according to the report by a team of 30 authors from 19 countries.   “Our lifestyles can change the trajectory of our mental and physical health,” said lead author Dr Scott Teasdale, a dietitian and Senior ...

Embargoed until 19:01 EDT Tuesday 12 August 2025 / 00:01 BST on Wednesday 13 August 2025 -With pictures- A new tool to understand how people imagine differently when reading could have potential implications for the treatment of mental ill health. The ReaderBank Imagination Quiz has been developed by a team of researchers led by Durham University, UK. The quiz identifies four “forces” of imagination - space and vision, voice and language, people models, and perspective. These forces have strong and specific connections to mental imagery, immersion in a story, daydreaming, and intrusive thoughts. This shows the complexity of people’s reading ...

A large-scale study from the University of Michigan and University of Minnesota finds no evidence for a long-believed association between musical training and enhanced neural processing of sounds at the early stages of auditory processing. Researchers attempted to recreate several results from past studies and found no evidence of several key findings. In this latest study, musicians demonstrated no greater ability to process speech in background sounds than non-musicians. Musicians also didn't have superior abilities to process changes in the pitch of speech. The study did find that early brain ...

For many breast cancer survivors, fatigue may linger long after treatment ends, which can have a significant impact on cognitive function, ability to work, and overall quality of life. A new study from George Mason University’s College of Public Health suggests that this is not just a subjective feeling but a measurable reality.  Ali Weinstein, professor of global and community health and senior scholar at the Center for the Advancement of Well-Being studied how breast cancer ...

In the quest for energy independence, researchers have studied solar thermoelectric generators (STEGs) as a promising source of solar electricity generation. Unlike the photovoltaics currently used in most solar panels, STEGs can harness all kinds of thermal energy in addition to sunlight. The simple devices have hot and cold sides with semiconductor materials in between, and the difference in temperature between the sides generates electricity through a physical phenomenon known as the Seebeck effect. But ...

BUFFALO, N.Y. — Last year, onlookers observed a startling site on China’s Qiantang River: waves forming a grid-like pattern. Dubbed the “matrix tide,” this complex wave pattern was caused by the river’s famed tidal bores that surge upstream against the current. Specifically, two shockwave-like tidal bores, known as undular bores, that spread along two different directions like ripples on a pond and collided with each other. This phenomenon is so complex that mathematicians don’t ...

August 12, 2025 Personalized pricing can backfire on companies, says study Toronto - Personalized pricing, where merchants adjust prices according to the pile of data about a consumer’s willingness to pay, has been criticized for its potential to unfairly drive-up prices for certain customers. But new research shows that the practice can also hurt sellers' profits. Consumers commonly experience personalized pricing through digital coupons or other discount offers they receive either as ...

UNIVERSITY PARK, Pa. — Animals like bats, whales and insects have long used acoustic signals for communication and navigation. Now, an international team of scientists have taken a page from nature's playbook to model micro-sized robots that use sound waves to coordinate into large swarms that exhibit intelligent-like behavior. The robot groups could one day carry out complex tasks like exploring disaster zones, cleaning up pollution, or performing medical treatments from inside the body, according to team lead Igor Aronson, Huck Chair Professor of Biomedical Engineering, ...

Researchers at the Optics and Photonics Research Center (CePOF) have succeeded in increasing the susceptibility of the fungus Candida albicans to drug treatment through light-activated therapy. The results of the study offer a promising alternative in the fight against antimicrobial resistance, a growing global problem that occurs when bacteria, viruses, fungi, and other parasites develop genetic mutations that render them resistant to drugs. In the study, published in the journal Photochemistry and Photobiology, the researchers evaluated photodynamic inactivation (PDI) combined with the antifungal ...

The underlying physics governing the center of our galaxy (the Galactic Center), due to its chaotic and complex nature, has been difficult to observe, model, and predict. Studying the region’s interactions and the environment where they occur helps to unravel the mystery and lead to a better understanding of the center of our, and even other, galaxies. The central region of the Milky Way, known as the Central Molecular Zone (CMZ), is a vast reservoir of interstellar gas and dust orbiting the center of the galaxy and an ideal place to study astrophysics in extreme environments. One particular site within the CMZ named ...

OKLAHOMA CITY – University of Oklahoma researchers are conducting a first-of-its-kind study to determine whether cannabis use affects recovery from the wounds associated with head and neck cancer surgery. The outcomes may have implications for other types of surgery and conditions. Lurdes Queimado, M.D., Ph.D., and Mark Mims, M.D., have been funded by the Presbyterian Health Foundation in Oklahoma City to lead the research, which will include 220 adult patients undergoing surgery for head and neck cancer and reconstruction after the tumor removal. Many such surgeries compromise both appearance and physiological ...

With large eyes, razor sharp teeth and a compact body built for hunting, Janjucetus dullardi is nothing like the gentle giants we know today, but this newly discovered ancient whale is one of their earliest cousins. Scientists at Museums Victoria’s Research Institute have described a new species of ancient whale from a 26-million-year-old fossil found near Jan Juc, on Wadawurrung Country, along Victoria’s Surf Coast. The discovery offers remarkable insight into the early evolution of baleen whales – the filter-feeding giants that now cruise our oceans. Janjucetus dullardi was no ocean giant – it was a fast, sharp-toothed ...
