Recent studies reveal significant undercounting of COVID-19 deaths and rising heart disease among women aged 25-44. New guidelines aim to improve cholesterol screening and reduce mortality, especially in vulnerable populations. These findings highlight ongoing health disparities and the need for targeted interventions.
A study in the Proceedings of the National Academy of Sciences has found that trees in cities like New York and Philadelphia start pollen production earlier and finish later due to light pollution, potentially extending the allergy season by up to 130 days; the effect is linked to plants using day length cues for flowering and leaf-out.
Scientists warn that this summer could bring above-average heat with deadlier impacts. El Niño is strengthening, likely intensifying extreme weather. Health systems, coastal infrastructure, and vulnerable communities face increased risks unless heat and climate plans are expanded and implemented.
