New research indicates that genetics play a significantly larger role in determining lifespan than previously understood, with approximately 55% of longevity being heritable, according to a study published in Science. This challenges prior estimates that placed the heritability of lifespan between 10% and 25%, according to Nature News. The findings are expected to aid in the identification of specific genes involved in aging and the development of treatments for age-related diseases.
In other health news, a study in JAMA Network Open revealed a concerning link between high-deductible health plans (HDHPs) and decreased survival rates for cancer patients, as reported by multiple news sources. The study found that individuals often delay or forgo necessary care due to high out-of-pocket costs. This issue is compounded by rising healthcare prices and increased enrollment in bronze ACA plans with high deductibles, particularly after the failure to extend critical tax credits. This potentially leads to worse health outcomes for those with limited financial resources.
Meanwhile, a University of Bonn study, as reported by multiple news sources, demonstrated the positive effects of an oat-based diet on individuals with metabolic syndrome. Participants with the condition experienced a significant reduction in LDL cholesterol and other benefits from a calorie-reduced diet of 300 grams of oatmeal per day, compared to a control group on a different calorie-reduced diet. The research revisits a historical approach to managing metabolic disorders, highlighting the pronounced positive effects of oats on individuals at risk of diabetes.
In other science and technology news, multiple news sources reported on a diverse range of developments. These include corrections to a Nature article on the Neolithic transition, which minimally affect its conclusions, advancements in AI world models such as Google DeepMind's Project Genie, and genetic autism research identifying convergent pathways. Northwestern University successfully used an artificial lung to bridge a patient to transplant, showcasing advancements in medical technology. These reports also covered business and tech news, such as Waymo's SFO taxi launch and Apple's revenue. Protests following ICE shootings in Minneapolis and power outages during the eastern US snowstorm, which analysis suggests were exacerbated by fossil fuel plant failures, were also reported.
