The move raised concerns about harmful mutations and genetic swamping — or loss of unique traits. However, a recent study co-authored by UCF Assistant Professor of Biology and Genomics and Bioinformatics faculty cluster member Robert Fitak, found that since the introduction, genetic variation has significantly improved; unique traits have been retained; and harmful mutations, while still present, are largely masked by the restored genetic variation.

Sweat does more than just cool down an overheating body. Measuring the chemical makeup of an individual’s sweat — specifically the levels of chloride, a chemical component of salt — can serve as an early warning system to help inform the diagnosis of cystic fibrosis, a genetic disease that damages the lungs and digestive system. 

In a groundbreaking study, University of Utah researchers found strong evidence that exposure to industrial pollutionduring pregnancy can shape a grandchild’s neurodevelopment. A child has a higher risk of an intellectual disability if their grandmothers lived near industrial facilities while pregnant with a parent, especially the mother. Higher density of industrial facilities corresponded to higher risk for the grandchild.
