Congrats to lab postdoc, Dr. Emily Kopania, on being selected for a Catalyst Award from the Center for Evolutionary Biology and Medicine! Her project will develop a Virtual Reality experience demonstrating to students how other species see the world through their differing visual systems.

There's this great showdown between Gothic and Brutalism a block from work at Pitt.
Who will win?

Lab purchase for equipment made in Canada only.
Guess who’s paying the tariff?
Hint: it’s not the company!

High altitude species have reduced olfactory receptor repertoires! The reduction has happened repeatedly throughout mammals.
Why?
We're not sure, but perhaps because there are fewer things to smell above the tree line!

The Mitochondrion.
What if we’d just named it the Powerhouse in the first place?
What would kids memorize for their tests then?!

Chromatin field, explain yourselves
A more positive "insulation score" indicates more chromatin interactions (i.e. less insulated),
and a lower insulation scores indicates fewer interactions (more insulated).
So about this word 'insulation'...

Research leads you to meet such neat people. I requested a copy of paper on lupus in a turtle and had a long conversation with a retired veterinarian, who went to check on paraffin slides in his garage! He's 92! We talked about lizards, sharks, and his time spotting Soviet submarines from a blimp!
