Brain circuit links social memory to fear, triggering aversion in mice
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.

Post-Seizure Sleep May Strengthen Epileptic Networks
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.
Trump administration to review stalled NIH DEI-related research grants
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.
Hidden Tree Offers Dual Benefits as Food and Medicine
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.

Largest Human Imaging Project Reaches 100,000 Volunteers, Aiming to Transform Disease Detection
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.
Cannabis Extract Shows Promise in Eliminating Dangerous Wildlife
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 Grows to 7 Feet, Aids Cancer Research
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.
