Researchers found dietary changes may help improve cognitive health and stave off dementia. A new study led by investigators from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute of MIT and Harvard suggests that a Mediterranean-style diet may help reduce dementia risk. The study, published in Nature Medicine, found…
VOLUME 29 August 28, 2025 Summary This volume highlights new research showing that certain prompting techniques can help reduce the risk of AI chatbots amplifying false medical information when users include fabricated terms in their queries. It also examines false claims linking vaccines to sudden infant death syndrome and the promotion of the industrial solvent…

Overcoming LLM limitations LLMs excel at understanding nuanced context, performing instinctive reasoning, and generating human-like interactions, making them ideal for agentic tools to then interpret intricate data and communicate effectively. Yet in a domain like health care where compliance, accuracy, and adherence to regulatory standards are non-negotiable—and where a wealth of structured resources like taxonomies,…
Ecologists have observed a species of nocturnal spider attracting prey to its web using the bioluminescent beacons of already trapped fireflies. This rare example of a predator exploiting its prey’s mating signal for its own gain is documented in the British Ecological Society’s Journal of Animal Ecology. Researchers at Tunghai University, Taiwan have observed sheet…
Whale sharks, the largest living fish species, are classified as endangered on the IUCN Red List of Threatened Species. Over the past 75 years, populations have declined by more than 50% worldwide, and by up to 63% in the Indo-Pacific region. Because whale sharks take up to 30 years to become sexually mature, populations can…
Clues about how worlds like Earth may have formed have been found buried at the heart of a spectacular ‘cosmic butterfly’. With the help of the James Webb Space Telescope, researchers say they have made a big leap forward in our understanding of how the raw material of rocky planets comes together. This cosmic dust…
The United States could safely drop tetanus and diphtheria booster shots for adults and save an estimated $1 billion a year, according to a new review led by researchers at Oregon Health & Science University. The safety and savings depend on maintaining strong childhood vaccination rates, researchers emphasized. “By maintaining high childhood vaccination coverage, we…
Plastics play a fundamental role in modern life, but their resistance to biodegradation makes them very difficult to dispose of. New research reveals how “plastivore” caterpillars can metabolically degrade plastics in a matter of days, not decades, and store them internally as body fat – but at what cost? In 2017, a groundbreaking study demonstrated that…
