The three-year project is focused on three cities in Ethiopia: Jigjiga, Semera and Logiya.&nbsp;<div><br /></div><div>The project’s novel approach to combating malaria combines on-the-ground knowledge of human and mosquito behaviors with detailed environmental imagery from drones and NASA satellites. Machine learning techniques will be applied to the data to develop a model — powered by artificial intelligence — for targeted public health interventions.&nbsp;</div><div><br /></div><div>The aim is to efficiently control populations of the invasive <i>Anopheles stephensi</i> mosquito by first, identifying water sources that are most likely to harbor the larvae during the dry season. And secondly, by sharing maps of these precise targets with local public health authorities — via a mobile phone app — to guide their larvae-eradication efforts in the most efficient and effective manner.&nbsp;</div><div><br /></div><div>The strategy is based on research on the ecology of <i>stephensi</i> in Jigjiga led by Gonzalo Vazquez-Prokopec, Emory professor of environmental sciences and co-principal investigator for the grant. “It sounds counterintuitive to focus mosquito-control efforts on the dry season,” Vazquez-Prokopec says. “Our research, however, shows that the dry season offers a perfect window of opportunity to cost-effectively control these mosquitoes.”&nbsp;</div><div><br /></div><div>Vazquez-Prokopec is an expert on the disease ecology of pathogens spread by vectors, such as mosquitoes.

His lab revealed how, if infected with a parasite, the female butterflies prefer to lay their eggs on a species of milkweed containing higher levels of a toxic chemical. The caterpillars eat the milkweed, ingest the toxin, and reduce the parasite load in their bodies.&nbsp;</p><p>With that finding, de Roode joined the vanguard of scientists uncovering how animals treat themselves for diseases.&nbsp;</p><p>“We showed how even an insect with a teeny-tiny brain can medicate,” de Roode says. “From there it was a natural progression to the understanding that, in principle, any animal can do it.”&nbsp;</p><p>In his new book, “Doctors by Nature: How Ants, Apes and Other Animals Heal Themselves,” de Roode explores the growing field of animal self-medication.

A sweet taste, for instance, signals energy-dense nutrients important to animals foraging for food — including humans. A bitter taste may warn of a toxic substance.&nbsp;<div><br /></div><div>“We use our sense of taste to decide what to eat and how much to eat,” says <a href="https://biology.emory.edu/home/people/bios/faculty/devineni-anita.html">Anita Devineni</a>, a neuroscientist and assistant professor in Emory University’s Department of Biology.&nbsp;</div><div><br /></div><div>Despite the importance of taste, little is known about how taste cues spark the firing of cells across a brain and evoke a variety of behavioral responses.

What makes a brain cell different from a skin cell or a lung cell is that a brain cell fires. Firing means that sodium ions flow in and out of the cell.
