An analysis of survey data from the past five years of U.S. presidential elections found that while ideological differences between races have declined sharply, differences by education have widened significantly. Today, less educated Americans tend to be more conservative. The paper was published in PNAS Nexus. The dominant political ideologies in the United States are conservatism, liberalism or progressivism, and centrism or centrism, with smaller currents including libertarianism, democratic socialism, populism, and Christian nationalism. Gallup’s 2025 average shows that 35% of Americans identify as conservative, 33% as moderate, and 28% as liberal, making conservatives the largest self-identified ideological group, but…

As adoption of medical AI rapidly expands, healthcare AI companies are moving from simply generating answers to proving why those answers should be trusted. OpenEvidence, an AI-powered medical search engine, has developed medical AI co-pilot capabilities that assess and visualize the quality of published evidence that is cited and used to inform all answers to clinical questions. The company claims this feature, called EvidenceGrade, adds an important layer of context to help incorporate medical evidence into high-stakes medical decisions. According to OpenEvidence, a well-known limitation of AI systems is that they ignore differences in the quality of multiple sources when…

Quasars rank among the brightest and most powerful objects in the universe. These are fueled by supermassive black holes at the centers of galaxies that consume surrounding matter, producing so much energy that they can be observed over billions of light-years. Now, an international team of researchers has identified 31 of the oldest quasars ever discovered, including the two oldest known examples. These unusual objects were already glowing with the light of about 1 trillion suns when the universe was only about 670 million years old. This discovery is astronomy and astrophysicsoffers an unprecedented glimpse into one of the earliest…

Viz.ai, an artificial intelligence-powered disease detection and care coordination platform, announced Thursday that it is partnering with Cortechs.ai, a platform for neuroimaging and quantitative analysis solutions, to expand its coverage of neurodegenerative diseases. The partnership will expand the company’s Viz Neuro Suite with an initial focus on multiple sclerosis (MS). Quantitative magnetic resonance imaging (MRI) analysis with Cortechs.ai’s NeuroQuant MS integrates directly into care coordination workflows. Viz.ai’s chief medical officer, Dr. Tim Showalter, told Fierce Healthcare in an emailed statement that MS is the “starting point” for the Viz Neuro Suite. “But we think this is the beginning of a…

Adult men who view pornography report decreased sexual function and lower overall satisfaction with their intimate lives compared to women who view similar content. These findings are a broad synthesis of existing research and were recently published in The Journal of Sex Medicine. The data perfectly highlights the contradiction, showing that higher levels of explicit media engagement among men correlates with worse sexual health outcomes. Erotic depictions have existed in various civilizations since ancient times. The integration of technology into everyday life, especially smartphones and high-speed internet, has made explicit content more accessible than ever. This rapid increase in accessibility…

Listen to the audio version of this article (generated by AI).Large-scale intensive pig farms that pump manure pollution into local waterways are not only impacting human health, but also threatening the existence of more than a dozen endangered species, according to a new study. Researchers examined the overlap between endangered species and intensive hog feeding operations (CAFOs) in the top three hog producing states (Iowa, Minnesota, and North Carolina) and found that 17 aquatic species that are threatened, endangered, or under review for listing share watersheds with hog CAFOs. For 10 of these species, shared watersheds are listed as “critical…

A new study funded by the National Institutes of Health could help answer important questions about how exposure to so-called permanent chemicals affects children’s long-term health. Dr. Abby Fleisch, a pediatric endocrinologist at Maine Health, received a grant from the NIH to study whether exposure to per- and polyfluoroalkyl substances (PFAS) early in life increases the risk of obesity, diabetes, and cardiovascular disease. PFAS are found in everything from nonstick cookware to food packaging. They don’t break down easily in the environment or in the body, and rising levels in waterways and the ground have led to dozens of dietary…

New research published in journal neuron We provide evidence that giving people immediate, real-time feedback about their success during a motor task significantly improves their ability to control machines. This real-time enhancement tends to be particularly useful when users have limited visual or physical sensations to guide their movements. This study suggests a promising strategy to enhance rehabilitation techniques and improve functional use of advanced prosthetics in stroke patients. Scientists and engineers are actively developing clinical interventions to help individuals restore or replace lost physical capacity. These interventions often rely on human-machine interfaces. Human-machine interfaces are systems that allow humans…

A US study found that when pregnant women follow nutritional guidelines, their exposure to many environmental chemicals from food and household products can be reduced. However, the authors warn that following a healthy diet rich in fruits and vegetables can also increase exposure to pesticides, and urge policy makers to include exposure to chemicals as a component of dietary guidelines. Diet exposes consumers to environmental chemicals, which can enter food through farming, processing, packaging, storage, and preparation.”What we found is that following the U.S. Dietary Guidelines may have two benefits: It helps meet nutritional needs during pregnancy, and it provides…

Having barely survived a weekday without a World Cup, we can finally get back to our new normal this afternoon with France 3-1 against Morocco. A father’s quest to cure his daughter Matt Wilsey has spent 10 years of tireless work and nearly $70 million trying to find a cure for his daughter’s ultra-rare genetic disease. Through his scientific adventures, Wilsey is painfully close to achieving his goal. His next challenge, convincing a skeptical Food and Drug Administration,…
