Research suggests antivirals targeting the Epstein-Barr virus (EBV) may be the most effective treatment for multiple sclerosis (MS). Studies found people with MS produce twice as many CD4 T-cells targeting proteins from actively replicating EBV compared to those without MS, indicating a distinct immune response. Researchers urge pharmaceutical companies to develop EBV-specific antiviral drugs for future MS therapy.

A year into Trump's second administration, trust in federal health institutions, particularly the Centers for Disease Control and Prevention, has significantly declined and become deeply partisan, according to a poll by the Harvard T.H. Chan School of Public Health and the de Beaumont Foundation’s Public Health Listening Lab.

A study from the Harvard T.H. Chan School of Public Health found that adults who engage in 90-119 minutes of weekly resistance training have a 13% lower risk of death from any cause, 19% lower risk of cardiovascular death, and 27% lower risk of neurological disease death compared to those who do no strength training. Combining resistance training with aerobic exercise further reduces mortality risk by up to 45%, while exceeding 120 minutes of resistance training per week offers no additional benefits.

Dr. Ken Berry, a Tennessee physician, claims he lost 70 pounds and reversed prediabetes by adopting a carnivore diet, citing growing interest in high-protein diets among Americans.

Nutrition experts debate the long-term health impacts of carnivore diets, which exclude plant-based foods.

A study published in the Journal of the American Geriatrics Society found a potential link between optimism and reduced dementia risk, with optimists showing a 15% lower risk. The research followed over 9,000 adults for 14 years, adjusting for factors like age and health conditions.
