This is really a stunning paper.
Cyanobacteria exposed to shorter days (in the lab) "rewire" their membrane lipids to anticipate cold weather.
When those cells are plunged into cold water, they have "two or three-times higher survival" than cells exposed to longer days.

New paper published in @NatureComms The 2023 fire season in Canada is a wake-up call: severe climate impacts on fire activity are arriving decades earlier than predicted. Building fire-resilient environments is now more critical than ever! @NRCan @CEF_CFR nature.com/articles/s41467-0…

"More than 4.4 billion people in poorer countries lack safe drinking water, a number more than twice as high as some other estimates"

Our new paper led by @kevcrose makes the case that aquatic deoxygenation has sufficient implications for the Earth system that it warrants inclusion in the planetary boundaries framework. doi.org/10.1038/s41559-024-0…

Excellent review/synthesis... worth checking out.

"Walkouts, petitions & tweets: how a grass-roots movement led by students, postdocs and tenured academics changed gov. policy on science funding."
Better pay for those funded by our tri-agency council. Definitely a *BIG* win. But still inequalities & short-term vision for most.
New article in @Nature by SOS Executive Director Kaitlin Kharas on how Canada boosted PhD and postdoc pay!
"The collective voices of graduate students and postdoctoral scholars are too powerful to be ignored."

It shouldn't have come to this but good to see alternatives for Can students coming to QC-hopefully more solutions will arise, esp for internat stds. Thx @mcgillu for sending the msg that stds are *welcome* here. Awards (80% eligibility) offset '24 tuition increases to '23 levels

There is a ton of misinformation in my replies so here is a primer on permafrost carbon. Permafrost stores a HUGE amount of carbon because ancient life took up CO2, built biomass, then died. That organic matter (~50% C) slowly accrued in Earth's best freezer for 1000s of yrs. 1/

🐟Traditional Inuit fishing sites are linked to Arctic char habitat use. A fantastic collaboration with fishers allowed to characterize winter habitats.

That rings a bell.

Freshwater ecosystems cover <1% of Earth's surface but hold >10% of all known species.
"Women feel driven out by problems with toxic workplace culture more often than by lack of work–life balance."
Study (N=7,195) finds compared to men, women have 44% higher odds of being pushed out of academia due to workplace atmosphere than pulled to a better opportunity elsewhere. Even after receiving tenure, women were still at increased risk of leaving.

@NatureClimate widespread oxygen loss in warming rivers in US + Central Europe, at rates higher than oceans but lower than coastal & lakes. Urban rivers warm up fastest; agricultural rivers lose oxygen fastest

#FactFriday Did you know that graduate students holding a Tricouncil award like #NSERC and #SSHRC can't afford to live in a 1-bedroom apartment in the city they study in. How can we expect researchers to make advances in Science when they can't make rent? 😱 #SupportOurScience

In our paper in @NatureGeosci, we find increasing concentrations of soluble phosphorus across the Great lakes Basin. Greater increases at higher latitudes suggest warming winters to be a potential driver #ClimateChange #waterquality #machinelearning @GWFpubs @LakeFutures
