A recent study suggests that daily calcium supplements do not increase the risk of dementia in women aged 70 and older, supporting their safety for bone health without added cognitive risk, though further research is needed to confirm these findings across diverse groups.
A study found that AI coding tools actually slow down developers by about 19%, contrary to expectations of increased speed, due to factors like over-optimism, AI unreliability, and complex repositories, highlighting that current AI tools may not improve productivity as hoped.
Recent studies show mixed results on the link between vitamin D deficiency and heart attacks, with some evidence suggesting supplementation may reduce major cardiovascular events, but large-scale trials have not confirmed a clear preventive benefit. Maintaining adequate vitamin D levels through safe sun exposure and diet is recommended, but supplements should be taken cautiously and under medical advice.
A study published in the British Journal of Sports Medicine reveals that walking for an hour daily can significantly increase life expectancy, potentially adding five to ten years to one's lifespan. The research, based on data from the 2019 American population, highlights that if Americans aged 40 and above were as active as the top 25% of the population, their life expectancy could increase by 5.3 years. Walking for 160 minutes daily could extend life expectancy by up to 10.9 years. The study underscores the profound impact of physical activity on longevity, comparable to the effects of smoking and high blood pressure.
A study by King’s College London found that feeding peanut butter to babies from infancy until age 5 can reduce the risk of developing peanut allergies by 71% up to age 13. This research, part of the LEAP-Trio study, suggests that early and regular peanut consumption can provide long-term protection against peanut allergies, even if peanut consumption is discontinued after age 5.
Former President Trump's testing czar, Dr. Brett Giroir, stated that Americans who expressed concerns about the COVID-19 vaccine deserve an apology in light of a new study showing rare but significant side effects, including neurological and immune reactions. The study, which involved about 100 million people, revealed that vaccinated individuals faced slightly increased risks of several medical conditions, such as myocarditis and Guillain-Barré syndrome. Giroir emphasized the need for open, honest, and transparent scientific discussion about vaccine-related risks and benefits, and criticized the suppression of such discussions during the pandemic.
A study published in JAMA Internal Medicine estimates that 64,565 pregnancies resulting from rape occurred in 14 states with abortion bans, despite exceptions for rape. The study highlights the limited access to legal abortions for rape survivors in these states, leading many to seek illegal procedures, self-managed abortions, or travel to states where abortion is legal. The findings underscore the need for national protection of the right to choose to terminate pregnancy, as legal exceptions for rape are hindered by stringent time limits and reporting requirements.
