The two most surprising things about being “over the hill” are realizing just how much I still don’t know, and recognizing that I’ll never know how much more I could have known.

Don't know where this is, but some shopkeeper (hair salon?) seems to get the Gen Z vibe of bringing internet subculture IRL. Printing out gifs, and sticking them in the window so that it doesn't get smashed.

1/4 ✏️🔬 New manuscript posted! A foray into bacteriophages alongside our lab’s main research! Drs. Sean Stephenson and Walaa Eid built this project from scratch, isolating and sequencing 10 phages using clinically relevant bacterial hosts: E. coli O1:K1:H7 and Klebsiella pneumoniae K3.

3/4 Phage therapy offers a potential treatment approach orthogonal to antibiotics: using bacteria-infecting viruses to kill bacterial targets. Our collection provides a starting point for screening; these isolates’ therapeutic safety and efficacy remain to be tested.

2/4 We found phages in wastewater from a university residence, treatment-plant influent and primary sludge—all without enrichment. We sequenced and biobanked 10 isolates spanning four genera, creating a local resource for further study. All genomes have been deposited in GenBank.
