Dozens of East End residents have contracted salmonella, with 58 patients treated at Stony Brook Southampton Hospital since July 1. Most were evaluated, treated, and discharged as health officials continue investigating the outbreak’s source; state and Southampton officials declined to comment, directing questions to Suffolk County Health Services which is coordinating the public health inquiry.
University of Tokyo researchers identify a hippocampus–amygdala circuit that binds the memory of a familiar mouse to fear, causing avoidance after aggressive encounters; using optogenetics they could strengthen or erase this aversion, with the nucleus accumbens helping translate memory and fear into avoidance. While demonstrated in mice, the findings offer clues about how social memory and negative emotions interact, with potential relevance for anxiety and depression in humans.
A nationwide study of 958 chronic-pain patients at pain centers across Japan found ADHD symptoms are significantly associated with more severe pain, suggesting addressing ADHD symptoms could help ease chronic pain; the findings were published in Scientific Reports and led by Satoshi Kasahara of the University of Tokyo.
A German shepherd named Inca obsessively sniffed her owner Colleen Ferguson’s breath, leading to a CT scan that found a golf-ball-sized lung tumor at stage 1 and a successful surgical removal with no further treatment. The story adds to evidence that dogs can detect cancer by scent, and researchers are developing an MIT‑based AI-powered “e-nose” to mimic canine olfaction for noninvasive cancer detection, currently being tested on urine samples with the goal of clinical use within two years and potential smartphone integration.
A Japan-led team identified a previously unknown “third cell” required to fully regenerate hair follicles and demonstrated a complete hair-growth cycle in mice by adding this cell to two existing follicle components, signaling potential new therapies for hair loss.
New Mayo Clinic findings indicate the brain may hijack memory-consolidation processes after a seizure, with nights of intensified deep (NREM) sleep and reduced REM sleep that strengthen seizure networks and potentially worsen epilepsy. This post-seizure consolidation could explain disease progression and points to a critical window for targeted neuromodulation therapies to disrupt the reinforced networks, an approach being explored by Mayo’s BIONIC initiative.
The Trump administration's move to cut NIH grants related to diversity, equity, and inclusion is being reconsidered after a legal settlement, allowing the agency to review previously frozen or denied applications without the influence of political directives, though future projects may face increased scrutiny.
Hymenaea courbaril, a tropical tree native to Latin America, has significant potential as both a food source and medicine, with its pulp, seeds, and bark containing valuable nutrients, antioxidants, and medicinal compounds. Its seed gum can be used as a natural thickener in food products, and traditional uses suggest health benefits, though more research is needed to confirm medicinal claims.
The article showcases 48 fascinating photos of the human body, highlighting its incredible ability to heal, adapt, and the various medical conditions and procedures, from wrinkles and extra teeth to complex surgeries and injuries.
Recent studies highlight potential environmental triggers for autism, such as pollution exposure during pregnancy, and reveal new insights into interstellar object 3I/ATLAS's tail behavior, a widespread health condition called CKM syndrome affecting nearly 90% of US adults, and the discovery of a prehistoric group in Japan with minimal Denisovan DNA. Additionally, Iceland reports its first mosquito sighting, and a 'wind phone' in Dorset explores grief communication.
The National Academy of Medicine elected 100 new members, including 90 regular and 10 international members, recognizing outstanding contributions in health, medicine, and public health to address pressing health challenges and advance medical sciences.
Scientists may have discovered a method to eliminate the chromosome linked to Down syndrome, raising hopes for potential prevention but also sparking ethical debates about eugenics and genetic modification.
The UK Biobank has completed its goal of scanning 100,000 volunteers' brains, hearts, and organs over an 11-year project, providing valuable data for early disease detection and research, with the use of AI to analyze the vast amount of imaging data.
Research shows that CBD derived from hemp effectively kills mosquito larvae, including resistant strains, offering a promising natural alternative to chemical insecticides for controlling disease-carrying mosquitoes while potentially reducing environmental impact.
Chance the Snapper, the alligator famously captured in Chicago in 2019, is now part of a scientific study on cancer led by Frank Robb and the Wise Laboratory of Environmental and Genetic Toxicology. The research aims to understand how alligators, despite exposure to environmental chemicals, have lower cancer rates compared to humans. This study could lead to breakthroughs in cancer treatment and prevention. Chance, now residing at the St. Augustine Alligator Farm, is contributing to this vital research, which requires ongoing support and resources.
