Dr. George Dimopoulos is a Professor at Johns Hopkins University, and Dr. Helen Lazear is an Assistant Professor at the University of North Carolina Chapel Hill. Dr. Dimopoulos studies mosquitoes, those pesky insects that annoy people by biting them and sucking their blood. But they also spread a number of diseases, including malaria and dengue virus.

Dr. Dimopoulos is developing various clever ways to prevent mosquitoes from transmitting diseases to humans. Dr. Lazear studies the Zika virus, which is also spread by mosquitoes and has been recognized as a cause of brain defects in infants when it infects pregnant women. Dr. Lazear studies how the virus gets into the nervous system, with a goal of identifying new ways to prevent disease.

Dr. Dimopoulos and Dr. Lazear discuss ways to control and prevent malaria, how worried we should be about Zika virus, and how climate change influences diseases spread by mosquitoes.

The MicroCase for listeners to solve is about Lukey Luke, a lobster fisherman who gets sick after going leaf peeping in New Hampshire.
