VANCOUVER, Wash. – While many studies have looked at possible evolutionary links between men’s strength and sexual behavior, a Washington State University study included data on women with a surprising result. Women, as well as men, who had greater upper body strength tended to have more lifetime sexual partners compared to their peers. The study, published in the journal Evolution and Human Behavior, was designed to test evolutionary theories for human sexual dimorphism—namely that in early human history there was likely a reproductive advantage selecting for men’s greater upper body strength.   Another ...

New research1 underscores the potential role of pork consumption in supporting dietary and muscle health in Korean older adults. Older adults are a nutritionally vulnerable population who often face unique challenges, including meeting daily protein and micronutrient requirements. The study,* conducted through a collaborative partnership between researchers from Gachon University in South Korea, Tufts University, Think Healthy Group, LLC, and other leading institutions, suggests that pork consumption may be positively linked to nutrient intake, diet quality and handgrip strength—an indicator of overall muscle strength in older adults. Using data from more than 2,000 ...

The global burden of anxiety- and depression-related disorders is on the rise. While multiple drugs have been developed to treat these conditions, current medications have several limitations, including slow action and adverse effects with long-term use. This underscores the urgent need for novel, rapidly-acting therapeutic agents with minimal side effects. The delta opioid receptor (DOP) plays a key role in mood regulation, making it a promising target for therapeutic intervention. Studies have shown that selective DOP agonists (compounds that activate DOP), such as SNC80 ...

CLEVELAND and CHAMPAIGN-URBANA, ILL.—Diamond, often celebrated for its unmatched hardness and transparency, has emerged as an exceptional material for high-power electronics and next-generation quantum optics. Diamond can be engineered to be as electrically conductive as a metal, by introducing impurities such as the element boron. Researchers from Case Western Reserve University and the University of Illinois Urbana-Champaign have now discovered another interesting property in diamonds with added boron, known as boron-doped diamonds. Their findings could pave the way for new types ...

A new study from Oxford University has uncovered why the deep neural networks (DNNs) that power modern artificial intelligence are so effective at learning from data. The new findings demonstrate that DNNs have an inbuilt ‘Occam's razor,’ meaning that when presented with multiple solutions that fit training data, they tend to favour those that are simpler. What is special about this version of Occam’s razor is that the bias exactly cancels the exponential growth of the number of possible solutions with complexity. The study has been published ...

An international team of researchers led by the University of California San Diego has developed a new strategy to enhance pharmaceutical production in Chinese hamster ovary (CHO) cells, which are commonly used to manufacture protein-based drugs for treating cancer, autoimmune diseases and much more. By knocking out a gene circuit responsible for producing lactic acid—a metabolite that makes the cells’ environment toxic—researchers eliminate a primary hurdle in developing cells that can produce higher amounts of pharmaceuticals like Herceptin and Rituximab, without compromising their growth or energy production. The research, published on Jan. 14 in Nature Metabolism, ...

New research funding will investigate the early stages of heart disease associated with chronic kidney disease led by the University of Birmingham. Dr Davor Pavlovic will lead an international research team after receiving almost £300,000 from the British Heart Foundation to understand the mechanisms driving the early stages of CKD-associated cardiomyopathy. The research approach will allow detailed investigation of cellular and electrophysiological changes before irreversible damage to the heart occurs. Researchers will also test whether in the setting of CKD, early treatment can reverse or prevent heart disease. The research will be ...

Wildlife trade poses one of the greatest threats to the survival of numerous species. According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) at least 50,000 species are involved in trade. However, while this figure already seems huge, it risks overlooking less traditional sectors of wildlife trade, such as the pet or fashion trade. For instance, recent data shows that the number of butterflies traded exceeds the total number of terrestrial arthropods in the IPBES assessment. This raises a critical question: How many ...

A new paper in Nicotine & Tobacco Research, published by Oxford University Press, finds that smoking has a negative effect on earnings among younger workers. This is particularly true among the less well educated. The adverse health effects of smoking are well known. Smoking increases the risk of various cancers, respiratory issues, and cardiovascular diseases, with approximately 14% of all deaths in 2019 attributed to smoking. Despite smoking rates declining since the 1990s, in 2019 18% of women and 27% of men in high income countries still smoked. Tobacco smoking has ...

Society is often vulnerable to disasters, but how humans manage during and after can turn devastation into opportunities for improved resilience. For instance, private wells are attracting attention as an alternative resource for securing water for daily use and consumption in the event the water supply is cut off after a disaster. However, there are few records on how wells are used in the confusion of disasters, so detailed research is needed to promote the use of emergency wells. Professor Takahiro Endo of the Graduate School of Sustainable System Sciences at Osaka Metropolitan University conducted a survey on the use ...

St. Petersburg, Fla -  Welcoming a newborn is something many couples dream of doing, but it can get complicated when conceiving becomes a roadblock. Infertility affects one in six people, but obesity can also be a problem. When diet and exercise aren’t enough to lose weight, bariatric surgery can become an option. Yet a new national survey by Orlando Health finds that 56% of Americans do not know that bariatric surgery is an effective way to improve fertility.   “Every day we have more patients ...

Optical microscopy has long been a fundamental tool for scientific discovery. Yet, traditional far-field techniques are limited by diffraction, restricting their resolution to hundreds of nanometers, which can be inadequate for capturing phenomena in quantum and solid-state materials. With the emergence of tip-based microscopy capable of achieving atomic-scale spatial resolution, near-field optical nano-spectroscopy and nano-imaging have evolved into versatile tools for characterizing the optical properties of materials at the nanoscale. When further combined with ultrafast pump-probe ...

Communities exposed to drinking water contaminated with manufactured chemicals known as per- and polyfluoroalkyl substances (PFAS) experience up to a 33% higher incidence of certain cancers, according to new research from the Keck School of Medicine of USC. The study, funded by the National Institutes of Health and just published in the Journal of Exposure Science and Environmental Epidemiology, is the first to examine cancer and PFAS contamination of drinking water in the U.S. PFAS, which are used in consumer products such as furniture and food packaging, have been found in about 45% of drinking water supplies across the United States. ...

Older Australian women are challenging traditional views of aging, embarking on solo road trips and travelling the country in search of adventure, personal growth and new horizons. Equipped with a caravan, campervan, or a sturdy 4WD and a tent, these women are navigating vast landscapes, from the dusty Oodnadatta Track to the spectacular Tasmanian wilderness. Margaret Yates, a PhD candidate from the University of Technology Sydney (UTS) Faculty of Health and a retired nurse, interviewed 29 women travellers to explore their motivations and experiences. The majority were over sixty and considered themselves ...

There has been a shift away from the use of more reliable hormonal methods of contraception to less reliable fertility awareness methods among women requesting abortion in England and Wales over the past 5 years, reveals research published online in the journal BMJ Sexual & Reproductive Health.   Use of the Pill, mini Pill, implants, patches, and vaginal rings has given way to more ‘natural’ methods, such as period tracking apps that highlight monthly peak fertility/ovulation, the findings ...

Implementing bans on the advertising, promotion, and sponsorship of tobacco products is linked to 20% lower odds of smoking, and 37% lower risk of taking up the habit, reveals a pooled data analysis of the available research, published online in Tobacco Control.   The findings indicate that these bans do influence behaviour, lending further weight to calls for their wider international implementation and enforcement, conclude the researchers. In 2019 alone, more than a billion people around the globe regularly smoked tobacco, and smoking caused nearly 8 million deaths, note the researchers. To curb the toll ...

A vascular ‘fingerprint’ on the light sensitive tissue layer at the back of the eye—the retina—can predict a person’s risk of stroke as accurately as traditional risk factors alone, but without the need for multiple invasive lab tests, finds research published online in the journal Heart.  The fingerprint, comprising 29 indicators of vascular health, is a practical and readily implementable approach that is particularly well suited for primary healthcare and low-resource settings, conclude the researchers. Stroke affects around 100 million people around the globe and ...

Mild cognitive impairment is linked to blood vessel dysfunction in the brain’s temporal lobes — the seat of memory — according to a new USC-led study. The findings, seen in people with and without signs of amyloid buildup in the brain, suggest that microvascular trouble may be an important, early biomarker for dementia as well as a potential target for therapy. The research, involving scientists from multiple universities, appears in the journal Neurology. “We’re studying ...
