Notre Dame researchers provide new genetic information about the circadian rhythms of the malaria mosquito

Author: William G. Gilroy

Anopheles gambie

A new study by a team of University of Notre Dame researchers offers a wealth of information about the rhythmic nature of gene expression in Anopheles gambiae, the mosquito species that transmits the malaria parasite from person to person. Each year, roughly 250 million people suffer from malaria and that results in one million deaths, mostly pregnant women and children under five years of age.

Mosquitoes, like all animals, show daily rhythms in behavior and physiology. The rhythmic behaviors of Anopheles gambiae include dusk mating swarms, nocturnal flight activity and feeding on sugar and blood-meal hosts and egg-laying. The exclusive biting of humans at night by Anopheles gambiae provides the basis of protection by insecticide-treated bed nets (ITNs) used while people are sleeping. This contrasts with the dengue/yellow fever mosquito Aedes aegypi, which bites during the day and to which ITNs afford no protection. Read More

Science dean to embark on second ride for rare disease research

Greg and Renate Crawford

Gregory P. Crawford, dean of the College of Science at the University of Notre Dame, and his wife, Renate, will for the second consecutive year set out on a remarkable bicycle ride this summer to support research seeking treatments and a cure for Niemann-Pick Type C (NPC), a rare and deadly neurodegenerative disease that primarily strikes children before or during adolescence.

The Crawfords will depart June 13 on “Road to Discovery,” a 2,200-mile ride from Boston to Dallas, with stops to visit NPC researchers and families, as well as Notre Dame alumni clubs, along the way. Read More
