A laboratory-based study suggests that inadequate vaccines could lead to the emergence of more virulent malaria strains, potentially making them more dangerous to non-immunized populations. The research found that immunity accelerates the evolution of virulence in malaria parasites, even after mosquito transmission.
Research finds that flood policy shifts are often driven by prevailing attitudes, technological resources and social values, not just crisis responses. Policymakers must consider these complex influences when planning for future events.
Research suggests that estrogen therapy does not reduce the risk of dementia in older women. The study found a 76% increased risk for probable dementia among those taking estrogen compared to placebo. Hormone therapy also increased the risk of mild cognitive impairment and decline in global cognitive function.
A study found that most people dislike yard signs due to their size, location, and content, leading to conflicts with neighbors. Cities may need to regulate these signs before they become a nuisance, especially as they become more common in neighborhoods around the country.
