Simple “gut reset” may stop weight gain after Ozempic or Wegovy

A new minimally invasive procedure may help people keep weight off after stopping popular drugs like Ozempic and semaglutide—something most patients struggle with. In a clinical trial, those who underwent a technique called duodenal mucosal resurfacing regained far less weight compared to others after discontinuing the medication. The procedure works by renewing the lining of … Read more

This new brain-like chip could slash AI energy use by 70%

A breakthrough in brain-inspired computing could make today’s energy-hungry AI systems far more efficient. Researchers have engineered a new nanoelectronic device using a modified form of hafnium oxide that mimics how neurons process and store information at the same time. Unlike conventional chips that waste energy moving data back and forth, this device operates with … Read more

Multi-region m6A epitranscriptome profiling of the human brain reveals spatial and temporal variation and enrichment of disease-associated loci

Nature Neuroscience, Published online: 09 December 2025; doi:10.1038/s41593-025-02112-z Epitranscriptomic (m6A) profiling across five human brain regions and developmental stages uncovers region-specific and age-specific dynamics, preferential enrichment in disease-associated genes, and colocalization with disease risk loci.
