A new perspective published in Nature Genetics offers the most detailed genetic explanation yet for why autism is diagnosed four times more often in boys than girls. Researchers from the Harvard/MIT MD-PhD Program propose that genes expressed by the so-called “inactive” X chromosome provide females with a biological buffer against autism-linked genetic mutations — a phenomenon known as the female protective effect.

A new federal lawsuit against Roblox and Epic Games alleges that both companies hired licensed psychologists to deliberately engineer addiction in children using casino-style operant conditioning techniques. The complaint, filed on behalf of a ten-year-old who began playing at age five, is part of a growing litigation campaign emboldened by the landmark social media addiction verdicts of March 2026.

A new study tracking 234 participants over three months finds that compulsive use of TikTok, Instagram Reels, and YouTube Shorts triggers a sequential psychological chain — first increasing loneliness, then anxiety, and finally reducing overall life satisfaction. Researchers warn that short videos do not simply waste time; they quietly displace the real-world connections that sustain mental health.

New research shows that even a modest reduction in smartphone use can produce dramatic mental health benefits. A major study published in PNAS Nexus found that participants who blocked mobile internet for just two weeks cut their screen time nearly in half, with improvements in depression comparable to antidepressant medication and cognitive gains equivalent to reversing a decade of age-related decline.

A California jury found Meta and YouTube liable for addicting a young woman to their platforms — but does heavy social media use actually meet the clinical definition of addiction? A new commentary in Nature by a Michigan State University researcher explains why scientists remain cautious about the label, and what needs to happen before medicine can formally answer that question.

A landmark study analyzing 6.14 million maternal-child health records has found that common prenatal medications — including certain antidepressants, antipsychotics, and statins — are associated with a significantly increased risk of autism in children. Mothers prescribed four or more of these medications simultaneously faced a 2.33-fold higher risk, with exposure rates nearly quadrupling between 2014 and 2023.

A federal bellwether trial is moving forward in Oakland, California, as school districts claim Meta, TikTok, Snap, and YouTube deliberately designed their platforms to foster addiction in children. U.S. District Judge Yvonne Gonzalez Rogers made clear the proceedings will be no-nonsense, setting the stage for a trial that could reshape how thousands of similar lawsuits are resolved.

A recent study reveals that fecal microbiota transplantation (FMT) could significantly improve symptoms of autism in children. Led by Dr. Priyom Bose, the innovative therapy uses hydrogen nanobubble water, avoiding traditional methods that require antibiotics. This research highlights the potential of gut microbiome manipulation in treating autism spectrum disorder.

A new review confirms that autistic children carry a significantly heavier burden of co-occurring health conditions than neurotypical peers. Across every age group studied, children with autism showed dramatically higher rates of gastrointestinal problems, sleep disorders, feeding difficulties, and anxiety — highlighting the urgent need for comprehensive, team-based care beyond the core autism diagnosis.

A new study published in JAMA Network Open finds that teenagers spend more than two hours on their smartphones every school day, checking their phones 64 times during school hours. Researchers from the University of North Carolina found this habit is directly fragmenting attention spans and weakening cognitive control in adolescents.
