Fish leave donuts on the ocean floor after they eat… but not the kind we like. “Grazing halos”—donut-shaped rings of bare sand where fish have eaten the algae and seaweed around coral reefs—are at the heart of Professor Theresa Ong’s research on foraging behavior and how the halo patterns could be used to monitor reef health. As coral reefs face growing threats from climate change, this approach offers new hope. (fb)

Give a rouse for Chance Bowman '23, a biochemistry graduate recently named a Hertz Fellow by the The Fannie & John Hertz Foundation. The prestigious fellowship will provide up to five years of funding for his doctoral studies in bioengineering. One of just 19 fellows selected nationwide, Bowman will combine his interests in stem cell biology and mathematical modeling to create biological tools that address difficult medical challenges. Congratulations, Chance! (fb)
