MacCormack Lab - Mount Allison University

I always thought it was crazy that Antarctic ice fish lost hemoglobin and myoglobin, but now you're telling me there's a second, unrelated group that have lost it in completely different way!?! The diversity of fishes is staggering.

Dentistry tools usually aren't that rusty.

This juvenile starling had a run in with a car on our street but seems to have gotten off with just a concussion. Thanks to the Hamilton Lab at Mount Allison for the advice and cage! It is now recovering at the Atlantic Wildlife Institute. (My kids named it 'Pothole')

Dear science journalism,

Please start including the funding source and whether it has been imperiled by the coup in your coverage of cool new science papers. The public should know the floor is being cut out from under us.

Are you searching for a postdoc in Saskatchewan? I have a 1-year opportunity (with possible extension), effective immediately! This opportunity is a Mitacs Elevate with the Canadian Prairies Prescribed Fire Exchange! Reach out if you're interested! 🐦🔥

The Ivy Lab! - Welcome to the Ivy Lab!

Do you like songbirds? Are you concerned about how wildfire smoke may impact their physiology?

I'm searching for graduate students who are interested in looking at the effect of wildfire smoke on songbird physiology! Come join my lab @usaskartsci.bsky.social!

Reading this in Attenborough's voice really did make this post better!

Screenshot of the first page of the Editorial, 'Science under siege: protecting scientific progress in turbulent times', written by James Briscoe, Craig Franklin, Daniel Gorelick. Elizabeth Patton and Michael Way. The publication information in the top line says, '© 2025. Published by The Company of Biologists | Journal of Experimental Biology (2025) 228, jeb250455. doi:10.1242/jeb.250455'. The first paragraph of the article says, 'As Editors-in-Chief of The Company of Biologists’ journals, we have been watching with growing concern the policy changes in the United States of America (USA) and the challenges that these are creating. It is unusual for us to comment on a nation’s science policies or politics, but the rapid ongoing developments in the USA and their potential impact on research worldwide are beyond the usual.'

The Editors-in-Chief of the 5 @biologists.bsky.social journals have written a joint Editorial, discussing the enormous challenges currently facing researchers in the US and how members of the community can support them through this difficult time

TT- position - An amazing opportunity! [must be able to teaching in French and English]

It’s Love Data Week, hosted by @icpsr.bsky.social
A busy and fun week for data folks. I’m a data and digital services librarian at a small liberal arts university in the Maritimes.

Received a request to review for a Wiley open access-only journal.

They charge authors >$9100 CAD + tax to publish.

Not a chance.

Publisher profiteering is not cool, don't support it by donating your labour. You don't have to be an activist, just don't actively contribute.

Well the award for most cowardly, boot-lickingest academic society has squarely gone to the American Society of Microbiology, who has taken down features of various non-white scientists. Absolutely pathetic behavior. Those articles are now coming up as “under review”. Truly sickening cowardice here.

It's been a few years, but I can remember every word of Little Blue Truck, while I still have to brush up on glycolysis every time I teach it!

I don't know a damned thing about Bluesky yet, but I do know I'm playing a solo acoustic gig at Staggers Pub & Grub in Dartmouth on Wednesday January 29th at 7pm. Roots/Americana, covers and a few originals...good food, great people...hope to see you there!

Taurine efflux counters the hydrodynamic impact of anaerobic metabolism to protect cardiorespiratory function under acute thermal stress in brook char (Salvelinus fontinalis) Summary: Cardiac taurine efflux is necessary to counteract swelling and protect function following osmotic stress caused by increased cardiac demands and the accumulation of anaerobic end products at ...

Thank you @jexpbiol.bsky.social for the great ECR spotlight on my former undergrad Nir El! He's a talented surgeon, a machine at the lab bench, and he made significant intellectual contributions to the associated publication.

New paper out in Ecology Letters, led by Alexa McQueen!

We don't talk enough about the biochemistry of Rudolph's nose.

I assume it involves a bioluminescent enzyme, and a fluorescent protein that red-shifts the light?

We're hiring for a 9-month term assistant professor position to replace my upcoming sabbatical. If you have biochemical expertise and want to build your teaching skills, join our department (and our amazing undergrads)!

Taurine efflux counters the hydrodynamic impact of anaerobic metabolism to protect cardiorespiratory function under acute thermal stress in brook char (Salvelinus fontinalis) Upper thermal tolerance may be limited by convective oxygen transport in fish, but the mechanisms constraining heart function remain elusive. The activation of anaerobic metabolism imposes an osmotic ...

Hot off the press in @jexpbiol.bsky.social! Undergrad-led study showing that cardiac taurine efflux under anaerobic conditions could play an important role in determining upper thermal tolerance in fish!

Our department is awesome - check it out!

I'm generally not a fan of winter, but the scenery on campus is certainly nice this time of year!
