The problem with Canada’s plan to buy scientific prestige The government’s plans to poach 100 US researchers might make good economic sense. But what about the existing community?

Absolutely essential reading for anyone considering those "unicorn" hiring positions in Canada. Observations from researchers who are already there: www.nature.com/articles/d41... 🧪

For #InternationalWomensDay I’m sharing my ongoing series of women in science through history. I’m now at 79.

Here’s to the day a scientist’s sex is no longer remarkable in any field.

Since last year I have added these 12 #linocut prints.

Axonal distribution of mitochondria maintains neuronal autophagy during aging via eIF2β Upregulation of the β subunit of translation initiation factor eIF2 underlies autophagy suppression and premature aging caused by disruption of axonal transport of mitochondria.

🧪Mitochondria control brain aging by ensuring proper protein degradation

Build up of excess proteins, such as amyloid and tau, can lead to Alzheimer's disease. This study shows that loss of mitochondria in axons causes build up of dysfunctional, damaging proteins.

I bet! That’s a lot to carry at once for one person. But I hope you know how appreciated your lived experience is in our field!

I don’t currently, due to visa limitations, but if you DM me an address, I’d be happy to send a few your way free of charge!

Anything for a fellow stroke researcher 😁

Don’t deprioritize curiosity-driven research Around the world, governments are demanding that research funding follow broader political priorities. They should be careful what they wish for.

“they should be careful not to deprioritize the kind of curiosity-driven, investigator-led research that has a strong track record in advancing humanity’s knowledge, producing the types of innovation that prosperity and well-being depend on.”

Thank you for taking the time to read it, and for your advocacy as a stroke survivor!

Pleased to share this review by our talented trainee, Geena! Check it out for the latest on #ferroptosis as a treatment target following #stroke 🧠

Lab morale got you down? Try a handbook Documents that lay out a research group’s ethos and practical guidelines are becoming increasingly popular in the academic community.

Scientists across the career spectrum are burnt out, & people are leaving STEM in startling numbers, particularly those from under-represented groups. A lab handbook can foster a more positive research culture. By @scattercushion.bsky.social @nature.com 🧪 www.nature.com/articles/d41...

A comprehensive meta-analysis of exogenous estrogen, progesterone, and testosterone in animal models of ischemic and hemorrhagic stroke - Biology of Sex Differences Background Exogenous sex hormones have been extensively studied for their influence on stroke risk and outcome. This meta-analysis served to update the pre-clinical acute ischemic stroke (AIS) literat...

So excited to announce my most recent project is now in press!

Our meta-analysis looks at the effects of exogenous #estrogen, #progesterone, and #testosterone in pre-clinical models for 3 subtypes of #stroke: AIS, ICH, and SAH.

How basic neuroscience has paved the path to new drugs A growing list of medications—such as zuranolone for postpartum depression, suzetrigine for pain, and the gepants class of migraine medicines—exist because of insights from basic research.

These drugs were not stumbled upon or borrowed from traditional remedies. They were born out of a long arc of studies in the lab, writes @alexkwan.bsky.social.

Spinal motor neurons in dazzling detail. ✨

Each green dot is a spinal motor neuron - crucial but rare cells making up just 1% of neurons in the spinal cord. In diseases like ALS, they are selectively damaged, making them of special interest to neuroscientists.

Lathrop’s scientific legacy is rarely acknowledged, but it should be. She was a scientist and #WomanInSTEM in her own right, and we have much to thank her for today!

Together, this work contributed to the discovery of estrogen receptors nearly 35 years later.

Lathrop went on to pass away of pernicious anemia at 50 years old- a condition that was rendered less fatal through discoveries made in animal models only a short time later.

Together, Lathrop and Loeb confirmed that these tumours were strain-specific, and that females with ovarectomies developed tumours at a lower rate than female mice who underwent pregnancy, linking them to sex hormones.

As Lathrop ramped up her breeding program in the early 1900s to support scientific research, she noticed that some of her in-bred strains developed cancerous lesions. She worked with pathologist Leo Loeb from @upenn.edu starting in 1910.
