Charlie BreitroseBryan Goodwin, chief biologist at Enanta Pharmaceuticals, and Watertown High School Senior Phil Centola look at a new microscope donated by the biotech company. Watertown-based Enanta Pharmaceuticals has a potential therapy for COVID-19 ready for human testing, and it also hopes to develop some future scientists with a donation to Watertown High School. On Monday morning, representatives from Enanta presented three new microscopes donated by the company to the WHS Science Department. The equipment can be hooked up to a tablet or cellphone to make it easier to see objects under magnification, and images can even be shared with other devices. The school had one of the microscopes, said Lynsey Kraemer, the district’s Science Curriculum Coordinator for Grades 8-12, but the district could not afford more.
