This semester, the students in my Cell and Molecular Biology of Aging class spent an hour a week helping seniors in public housing, adult day programs, and senior centers in the Boston area.

Thread. 1/

We collaborated with Little Brothers-Friends of the Elderly @LBFoE_Boston, a non-profit organization committed to relieving isolation and loneliness among the elderly through intergenerational programs. 2/

How do worms find a safe environment with food?

We found out that they use their brain to avoid bacteria that don’t protect them.

Read our paper to learn more!

Or better yet, join our lab! There are so many cool open questions that you could answer!

doi.org/10.1371/journa… Down in the microbial battlefield where worms are trying to find food, the weapon of choice is hydrogen peroxide.

We found out that worms assess faithfully the threat of hydrogen peroxide via sensory perception!

Once again, I shook up my Cell and Molecular Biology of Aging class, this time due to the #covid19 pandemic.

Thread. 1/ First, while my class is, on the surface, about the recent scientific discoveries that transformed our understanding of aging…

the real goal is to help upper-level undergrads and grad students to become judicious and informed citizens. 2/

Hey twitterworld! I am super excited to share our new paper!

We show that worms use their brain to decide whether to induce their hydrogen peroxide defenses or use those of E. coli.

This semester I shook up my Cell and Molecular Biology of Aging class by adding a Service-Learning component.

Thread. 1/ My 17 students spent over a hundred hours baking, painting nails, exercising, playing bingo, providing tech support, and socializing with seniors in six nearby assisted-living facilities.

Why? 2/
