Daily physical activity, even at light intensities, linked to lower cancer risk
In a prospective cohort study of more than 85,000 adults in the United Kingdom, researchers at the National Institutes of Health (NIH) and University of Oxford found that individuals who engaged in light- and moderate-to-vigorous-intensity daily physical activity had a lower risk of cancer than individuals who were more sedentary. The findings, published March 26, 2025, in British Journal of Sports Medicine, are among the first to evaluate the cancer risk reduction associated with light-intensity activities such as doing errands and performing household chores.
Potential ‘molecular mimics’ may be behind COVID-induced autoimmune disease
COVID infection has been linked to a higher risk of autoimmune disorders, including rheumatoid arthritis and type 1 diabetes. But why the virus might cause the body’s immune system to go haywire remains unknown, making it difficult to develop therapies to avoid autoimmunity. One hypothesis is that viral “molecular mimics” that resemble the body’s own proteins trigger an immune response against the virus—and healthy tissues get caught in the crossfire.

In the fight against malaria, controlling the mosquito population is crucial. Several methods are currently used to reduce mosquito numbers and malaria risk. One of these includes the antiparasitic medication ivermectin. When mosquitoes ingest blood containing ivermectin, it shortens the insect’s lifespan and helps decrease the spread of malaria.
