A major Swedish study of 3.7 million people has found that rare TORCH infections passed from a pregnant woman to the fetus are linked to much higher risks of autism and intellectual disability later in life. Children with a congenital TORCH infection were about three times more likely to be diagnosed with autism, more than seven times more likely to have an intellectual disability, and up to 30 times more likely to have severe to profound intellectual disability.

A new experimental drug called CS18 may help break through cancer drug resistance by disabling several of the defenses tumors use to survive treatment. It strengthened existing therapies, restored drug sensitivity in resistant lung cancer cells, and slowed tumor growth in animal models.

Caffeine may make sleep less restorative even when you fall asleep normally and stay in bed for eight hours, with EEG recordings revealing fewer of the slow brain waves associated with deep sleep. Individual sensitivity varies dramatically, meaning even caffeine consumed earlier in the day could affect nighttime recovery for some people.

Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. The discovery could lead to new treatments that target the brain's dopamine system.

Scientists have found that the human brain develops from two distinct cellular systems, suggesting that evolution fused together two ancient nervous systems with very different jobs. The discovery also allowed researchers to grow human hindbrain neurons in the lab, opening new possibilities for studying ALS, spinal muscular atrophy, and other brainstem diseases.

A sweeping review of more than 153,000 adults found that calcium and vitamin D supplements, alone or together, do little to prevent fractures or falls in most older people. Researchers say the findings challenge routine supplementation for prevention and point instead toward strategies such as balance and resistance exercise.

Researchers have uncovered a hidden molecular warning sign of inflammatory bowel disease (IBD) that can linger even when patients feel well and appear to be in remission. By studying around 900 human gut biopsies and patient-derived mini-intestines, the team found that intestinal cells can remain unusually primed to die, creating a “smoldering” defect that may help drive future flare-ups.
