Jury finds Meta and YouTube liable in landmark social media addiction case

The verdict validates a novel legal theory and could reshape how the biggest platforms are designed and defended in court.

A Los Angeles jury ruled this week that Meta and YouTube negligently designed their platforms in ways that caused measurable psychological harm to a now 20-year-old plaintiff identified as K.G.M., who sued over features like infinite scroll and algorithmic recommendations that she says led to anxiety and depression. The jury awarded $3 million in compensatory damages. TikTok and Snap settled before the trial began.

Plaintiffs argued the companies built products as addictive as cigarettes or digital casinos and should be held personally liable — drawing a direct line to the legal strategy that eventually brought down Big Tobacco last century.

Thousands of similar cases from parents, school districts and state attorneys general are still outstanding, and the verdict could expose the companies to significantly more in damages or force changes to how the apps operate. Another trial is set for Los Angeles in July. The New York Times and Reuters have more.

Match Day 2026 broke records; Family medicine is flashing warning signs

The largest residency match in history still left nearly 900 family medicine slots unfilled, and the NRMP is now standing up a formal review of the pipeline.

The 2026 Main Residency Match was the biggest in the program's 74-year history, with more than 53,000 applicants and 38,354 future physicians matching to first-year residency positions. Primary care remained the largest share of the match by volume, but the numbers inside that category tell a more complicated story. Family medicine offered 5,491 positions, which is 134 more than last year, but the fill rate slipped from 85% to 83.6%, leaving 899 slots empty.

The National Resident Matching Program (NRMP) announced it will convene a Blue Ribbon Panel to examine why medical students continue to pass on the specialty. Immigration policy is adding pressure to the pipeline as well: foreign-born international medical graduates requiring visa sponsorship matched at a five-year low of 54.4%, a group that has historically filled primary care gaps in rural and underserved communities.

Caffeine can restore memory lost due to sleep deprivation, study finds

Researchers identified a specific brain circuit disrupted by sleep loss. Caffeine targets it directly.

New research from the National University of Singapore suggests caffeine can restore memory function impaired by sleep deprivation by targeting specific brain pathways. In a study published in Neuropsychopharmacology, researchers found that sleep loss disrupted synaptic activity in the hippocampus, a region critical for memory, leading to deficits in social recognition. However, caffeine intake restored normal neural communication and reversed these memory impairments without overstimulating the brain. The findings highlight caffeine’s potential to selectively repair cognitive function affected by sleep loss and could inform future therapies aimed at mitigating sleep-related cognitive decline.
