Summary: Grounding—also called earthing—is the practice of physically connecting the body to the Earth’s surface. It has re-emerged as a wellness trend and now includes products such as grounding mats and sheets intended to simulate direct contact with the ground. Advocates report benefits for sleep, mood, inflammation and recovery after exercise, but rigorous scientific evidence … Read more

Summary: Two landmark studies have mapped the cellular complexity of glioblastoma—the most aggressive form of brain cancer—providing detailed insight into how its varied cells evolve and survive therapy. By applying single-nucleus RNA sequencing to more than 430,000 cells from 59 patients, researchers uncovered three previously unrecognized malignant cell states and defined three broad cellular “ecosystems” … Read more

Summary: A major new systematic analysis of more than 8 million adults shows that each additional 100 grams per day of ultra-processed food is linked to a significantly higher risk of hypertension, cardiovascular events, digestive disease, cancer, and death. Ultra-processed foods—such as sugar‑sweetened beverages, potato chips, packaged cookies and many ready‑to‑eat snacks—are typically high in … Read more

Summary: New research reveals that female digger wasps can track and manage up to nine separate burrows at once, provisioning their larvae in a precise sequence and adjusting that schedule when larvae die or have already received more food. Even when nests are dug in bare sand among hundreds of similar burrows, these mothers misdeliver … Read more

Summary: A new study highlights how developmental prosopagnosia — commonly called face blindness — affects daily life for many people who otherwise have normal vision, memory, and intelligence. Those with the condition often fail to recognise familiar people, even close family and long-term partners, and rely on exhausting or unreliable strategies such as notes, clothing … Read more

Summary: A large new study finds that adolescents with abdominal obesity show larger volumes in brain regions linked to memory and emotional regulation, raising concerns about how excess body fat may influence brain development. MRI scans of over 3,300 young people revealed enlarged hippocampus and amygdala in those with abdominal obesity—especially among teens with higher … Read more

Summary: New research shows that the brain contains neurons that track our position within a sequence of actions — not just our physical position in space. In mice, scientists discovered “goal-progress cells” in the cortex that fire according to how far an animal has progressed through a behavioral task. These cells enable animals to predict … Read more

Summary: A new study finds that even a short period of sleep deprivation triggers increases in inflammatory proteins in the blood that are linked to cardiovascular disease. After only three nights of sleeping about four hours per night, healthy young men showed higher levels of proteins associated with heart failure and coronary artery disease. Although … Read more

Summary: People who experience high levels of distress and functional impairment from excessive social media use are significantly more likely to believe and engage with fake news. Researchers report that individuals with problematic social media habits are more inclined to click, like, comment on, and share false stories, regardless of the stories’ accuracy. A new … Read more

Summary: Researchers have created an AI algorithm that can identify distinct neuron types from brain activity recordings with around 95% accuracy—without requiring genetic modification. By tagging specific neurons with light-sensitive markers and recording their unique electrical waveforms, the team built a training library that enabled the AI to classify neuron types in both mice and … Read more
