CONCLUSIONS: The majority of the 5Ms are covered in the curriculum, though notable gaps remain in several subcategories. Recommendations include strengthening preclinical exposure to concepts students will encounter in clinicals, such as pharmacology and delirium. This is the first known published study to explicitly identify how the 5Ms are covered in a U.S. undergraduate medical school curriculum.

ObjectiveThis study examines associations between neighborhood socioeconomic disadvantage during adolescence and early adulthood and chronic disease accumulation in mid- to late life.MethodsUsing Panel Study of Income Dynamics data linked to U.S. Census and American Community Survey data, we identify four trajectories of neighborhood disadvantage, namely persistent disadvantage, increasing disadvantage, decreasing disadvantage, and persistent advantage, and estimate their associations with...

Scientists are testing a counterintuitive way to fight mesothelioma, an aggressive asbestos-linked cancer with few effective treatments. A new experimental mesothelioma drug kills cancer cells by disabling PRX3, an antioxidant defense that tumors use to survive intense oxidative stress. In an early clinical trial, it controlled disease progression in 67% of patients and produced encouraging survival results, raising hopes that the strategy could eventually be used against other cancers.

Scientists found that black and green Japanese rice contain unusual, potentially beneficial fats and may be digested more slowly than ordinary white rice. The combination could make these colorful varieties promising ingredients for foods designed to support blood sugar and metabolic health.

Scientists discovered a hidden “immune organ” inside the skull that acts as a rapid first responder against brain cancer in mice. Strengthening this local immune defense improved tumor rejection and survival, raising the possibility of new treatments that target the skull directly.

Seismic activity around the Punggye-ri test site has increased since a large nuclear explosion in 2017

Ecologists testing “assisted migration” are pushing seedlings to the limits—and finding that location matters

Scientists have discovered that some severe genetic disorders linked to rapid aging may be driven not just by damaged DNA, but by the body’s overreaction to that damage. When broken DNA fragments leak into the wrong part of a cell, an immune sensor called cGAS can mistake them for signs of a viral infection, triggering chronic inflammation and even interfering with DNA repair itself.

Eating four to six servings of whole grains a day may deliver meaningful benefits for heart health, according to a large review of 87 clinical trials. Researchers found improvements in body weight, waist size, blood pressure, cholesterol, blood sugar, triglycerides, and some markers of inflammation.

Scientists reconstructed videos from the brain activity of mice, producing 10-second clips based only on signals from neurons in the visual cortex. The breakthrough could help reveal how the brain reshapes what we see before it becomes our perception of reality.
