Results from a large-scale international clinical trial led by researchers at University College London (UCL) and the London School of Hygiene and Tropical Medicine (LSHTM) show that AI technology is effective in planning life-saving radiotherapy for cervical and prostate cancer. 94% of cervical cancer deaths occur in low- and middle-income countries (350,000 women will die in 2022). Radiotherapy is the main treatment modality, but currently only 10% of people in low-income countries who require radiotherapy receive it (in middle-income countries, this figure is 40%), and the lack of skilled professionals is one of the major barriers. Researchers say AI technology…

Correlated and entangled photon pairs are essential tools in quantum optics. Scientists typically create these photon pairs through a process called spontaneous parametric downconversion (SPDC). In this process, a powerful and highly stable laser shines onto a nonlinear crystal. Because SPDC relies so heavily on coherent laser light, researchers have long considered the technology impractical outside of carefully controlled laboratory environments. Recent studies have shown that SPDCs do not actually require perfectly coherent light to function. Even partially coherent light sources can generate correlated photon pairs and can also transfer some of their unique coherence properties to the generated photons.…

The explosive growth of electric vehicles has intensified the search for ways to increase the energy efficiency of electric motors. One of the big challenges is iron loss, also known as magnetic hysteresis loss. Iron losses occur when the magnetic field inside the motor repeatedly reverses direction. This process wastes energy as heat inside the motor core, which is made of soft magnetic material. Since electric motors often operate at high temperatures, thermal effects can also partially demagnetize these materials, further complicating the energy loss issue. A key factor behind these effects is the behavior of magnetic domains, which are…

In obese pregnant rats, chia seed enrichment altered omega-3 metabolism and increased DHA availability in maternal tissues, placenta, and fetal brain lipid profiles during critical developmental periods. Study: Enhancement of chia seeds in high-fat, high-sugar diet-induced obesity: a strategy to increase DHA levels in maternal tissues, fetal placenta, and brain during pregnancy. Image credit: The Very Hungry Owl / Shutterstock In a recent study published in the journal Prostaglandins, leukotrienes, essential fatty acidsResearchers investigated whether adding chia seeds to a high-fat, high-sugar diet during pregnancy increases the availability of docosahexaenoic acid (DHA) in maternal tissues, placenta, and fetal brain in…

New research from the University of Adelaide suggests that the ancient Tethyan Sea played a major role in shaping the landscape of Central Asia during the Cretaceous period, long before the rise of the Himalayas. The research team reached this conclusion through extensive data analysis combining hundreds of thermal history models collected from more than 30 years of geological surveys across Central Asia. Scientists often link the region’s landscape to a combination of tectonic activity, climate change, and processes deep in the Earth’s mantle over the past 250 million years. But new discoveries show there’s another dominant force. “We found…

Studies in mice reveal how aging immune cells impair memory outside the brain and show that blocking CD8+ T cell activity or their secreted factor, granzyme K, can help restore cognitive abilities in older animals. Study: Aged circulating CD8+ T cells and their secreted factors cause cognitive decline. Image credit: Juan Gaertner / Shutterstock Recent mouse research has been published in a magazine immunity suggest that aged circulating cluster of differentiation 8 (CD8+) T cells and their secreted factors may cause hippocampus-dependent cognitive decline. Aging CD8+ T cells and cognition Aging is associated with cognitive decline, and identifying the underlying…

Coffee has been part of human culture for over 600 years and remains one of the world’s most popular drinks today. On average, people now consume about 2 kilograms of coffee per person per year, and many have strong opinions about brewing methods, beans, and blends. Genetics also influences how much coffee people enjoy, which can influence both caffeine metabolism and the brain’s reward system. Coffee can temporarily increase blood pressure, especially in people who don’t drink much coffee or who already have high blood pressure. But that doesn’t mean you need to cut coffee out of your daily routine…

A new study suggests that AI-powered retinal imaging may capture systemic aging signals associated with weak bones and provide a potential low-cost route to identify people who need formal osteoporosis evaluation before fractures occur. Research: Retinal biological age correlates with bone density and fracture risk score and predicts osteoporosis development. Image credit: Steve Bottoms / Shutterstock In a recent study published in the journal PLOS Digital HealthResearchers evaluated whether RetiAGE, an AI-derived probability score, could help address the limitations of current osteoporosis risk screening approaches. This model uses estimates of retinal biological age as a potential marker of systemic skeletal…

A nationally recognized medical AI system interpreted images, electrocardiograms, and clinical documents during live diagnostic chats and outperformed primary care physicians in mock consultations, while raising urgent questions about how such tools should be tested before actual treatment. Research: Advances in conversational diagnostic AI through multimodal reasoning. Image credit: Explode / Shutterstock In a recent study published in the journal natural medicineresearchers describe the development of a multimodal extension of the Articulate Medical Intelligence Explorer (AMIE). The model is designed to utilize a state-aware reasoning framework to manage clinical conversations and interpret visual artifacts. The study then conducted a randomized,…

Scrolling through an endless feed of short videos can disrupt a good night’s sleep, but poor sleep quality can also motivate you to keep scrolling in a continuous loop. Researchers found that daytime fatigue acts as a gateway symptom, making individuals more likely to lose control of their video viewing. The study was published in the journal Personality and Individual Differences. Short-form media platforms have changed the way people consume digital content. The application features short clips combined with advanced recommendation codes that learn exactly what the user wants to see. This special design lowers the mental barrier to entry…
