A black hole in the early universe? Sometimes I like to imagine that I operate a telescope, not a microscope 😁. The hole in the middle of the image is actually a blood vessel. The stars are astrocytes🟡 in the human brain, interacting with beta-amyloid🔵. The brain is from a donor with #Alzheimer.

Almost every line of this story would have been simply unbelievable a few months ago:
—Pioneering cancer researcher;
—*Arrested* at airport in Boston;
—Now indefinite ICE detention in Louisiana;
—"Crime": not declaring some frog-embryo samples for research.

New images could change cancer diagnostics, but ICE detained the Harvard scientist who analyzes them
Without scientist Kseniia Petrova’s expertise, no one can fully unlock the data’s potential, putting crucial advancements in early cancer detection at risk.

One of our undergraduate students in philosophy at Columbia, Mohsen Mahdawi, has been arrested by ICE at an immigration appointment (that he thought was for his citizenship application) in Vermont. I am standing up to say: hands off our students.

A package of research papers from the MICrONS (Machine Intelligence from Cortical Networks) consortium in Nature and Nature Methods provides a detailed map of mouse brain cell structure and connections, offering insights into how they relate to activity in the mouse brain. 🧪
The MICrONS Project
An unprecedented dataset of high resolution anatomical images of individual cells in mouse visual cortex, mapped on to their responses. This integrated view of function and structure lays a foundation for discovering the computational bases of cortical circuits.

The authors discuss what they describe as the Trump administration's "assault" on science and scientists, and what the response should be. #StandUpForScience

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back.
This was the largest political gathering in Denver since Obama in 2008.
Also bigger than the 2024 DNC.
And the largest ever rally in Bernie’s career (and obviously, mine too).

Attracting talent, offering safe spaces is good. If it goes hand in hand with extra resources for science / education.
If not, these plans will create extra competition in already precarious systems.
The fact is, many European countries cut on research spending.

Changes to MSc, PhD and postdoc funding programs from 🇨🇦 tri councils. Harmonization across councils, more awards, and new eligibility for international PhD and postdoc applicants!
NSERC - Latest News - Launch of the new Harmonized Tri-agency Scholarship and Fellowship programs
As announced in Budget 2024, the scholarship and fellowship programs administered by the three federal research funding agencies – the Canadian Institutes of Health Research (CIHR), the Natural Sciences and Engineering Research Council (NSERC), and the Social Sciences and Humanities Research Council (SSHRC) – have been streamlined into a new harmonized talent program called the Canada Research Training Awards Suite (CRTAS) that will open for applications in summer 2025.
