Through the southern reaches of Texas, communities are scattered across a flat landscape of dry brush lands, ranches and agricultural fields. This large rural region near the U.S.-Mexico border is known for its persistent poverty. Over 25% of the families here live in poverty, and many lack access to basic services like water, sewer and primary health care. This is also home to the Eagle Ford shale, where domestic oil and gas production has boomed. The Eagle Ford is widely considered the most profitable U.S. shale play, producing more than 1.2 million barrels of oil daily in 2019, up from fewer than 350,000 barrels per day just a decade earlier. The rapid production growth here has not led to substantial shared economic benefits at the local level, however. Low-income communities and co...

Tsetse flies are bloodthirsty. Natives of sub-Saharan Africa, tsetse flies can transmit the microbe Trypanosoma when they take a blood meal. That’s the protozoan that causes African sleeping sickness in people; without treatment, it’s fatal, and millions of people are at risk due to the bite of a tsetse fly. My entomology research focuses on insects that feed on the blood of people and animals. From a human health standpoint, understanding what makes all these bugs tick is key to developing ways to control them and prevent transmission of the diseases they carry, such as malaria, dengue, Lyme disease, West Nile virus and many others. Tsetse flies stand out from their blood-feeding cousins the mosquitoes and ticks because of their unique reproductive biology. They give birth to live young...
