Coastal elevations in sections of the Everglades are up by over 2 inches due to major hurricanes washing up sediment and mangrove tree-boosting nutrients, according to a study in Proceedings of the National Academy of Sciences. Hurricanes in 2005 and 2017 deposited sediment and mud, "and we found out this provides natural fertilization that helps the mangroves," said study lead author Edward Castaneda-Moya.

Researchers say people and animals who populated the area at that time ate a diet that included catfish and tilapia before climate change dried up the lakes, swamps and ponds.

Hispanic and non-Hispanic post-menopausal women had a 6% increased fasting insulin and an over 7% increase in insulin resistance for every additional hour in average sitting time per day, which were 8.5 hours and 9 hours, respectively. The study published in the Journal of the American Heart Association also revealed that every 15 minutes added in uninterrupted sitting was tied to approximately 5% higher fasting blood glucose among Hispanic women, compared to less than 1% increase among non-Hispanic women.
