Albatross flight inspires next generation of drones
Science writers highlight UC aerospace engineering research
Earth.com highlighted aerospace engineering research at the University of Cincinnati to develop efficient drones that can harness the power of the wind like an albatross.
UC College of Engineering and Applied Science Assistant Professor Sameh Eisa and his students received a grant from the Defense Advanced Research Projects Agency to develop a drone that can optimize flight through dynamic soaring like the oceangoing birds.

Albatrosses have the largest wingspan of any living bird. But Eisa said it's how they use those wings that make them world-class flyers.
The birds tack into the wind like a sailboat to gain lift and altitude, finding faster air currents as they climb. When they eventually lose the forward momentum needed to stay in the air, they turn, harnessing the kinetic energy of gravity and wind that propels them forward. At the bottom of this glide path, sometimes mere inches off the water, they turn back into the wind and do it again — all without wasting a single wingbeat.
The birds are able to gauge wind speed and direction through their sensitive nostrils, allowing them to make fine flight adjustments to maximize each leg of upward and downward flight path.
“Nature has been optimizing flight for millions of years of evolution. So to take this gift from nature and make it available to humanity is engineering at its best,” Eisa said.

Putting preschool into perspective

Preschool and childcare can be difficult to navigate for parents, as Spectrum News 1 Ohio recently reported. Waitlists are long, and factors like cost, location and transportation can limit options. According to a recent study published by The Annie E. Casey Foundation, only 41% of 3- to 4-year-olds in Ohio were enrolled in preschool between 2020 and 2024 — a 4% decrease from pre-pandemic numbers. For University of Cincinnati early childhood education faculty member Chad Nunamaker, that statistic has caveats.

The United States is heavily reliant on imported rare-earth materials to make permanent magnets. Ugochukwu Philip Ochieze, materials science student at the University of Cincinnati, is studying how to use common materials to create permanent magnets, eliminating the need for expensive and scarce rare-earth materials. Pursuing his PhD, Ochieze was named Graduate Student Engineer of the Month by the College of Engineering and Applied Science.
