โœจ Blinking #nanobodies that work for single-molecule localization ๐Ÿ”ฌ
Our new preprint shows that the self-blinking dye JF635b restores robust, buffer-free blinking in #nanobodies, enabling reliable #dSTORM, #MINFLUX, and more, without chemical-switching buffers. Opening new possibilities for #ExM!

Large Language Muddle | The Editors The AI upheaval is unique in its ability to metabolize any number of dread-inducing transformations. The university is becoming more corporate, more politically oppressive, and all but hostile to the ...

YES! THIS on GenAI!

Please read this absolutely splendid piece of writing that had me cheering, a little bit weepy, and writing in the margins:

"An extraordinary amount of money is spent by the AI industry to ensure that acquiescence is the only plausible response. But marketing is not destiny."

Not only is the ratio of Al's resource rapacity to its productive utility indefensibly and irremediably skewed, Al-made material is itself a waste product: flimsy, shoddy, disposable, a single-use plastic of the mind.

Not only is the ratio of Al's resource rapacity to its productive utility indefensibly and irremediably skewed, Al-made material is itself a waste product: flimsy, shoddy, disposable, a single-use plastic of the mind.

I also loved this observation. The techโ€™s true โ€œinnovationโ€ is its utter disregard for efficiency. It โ€œworksโ€ bc it accepts the most irresponsibly resource-intensive production method imaginable. What matters is not what it costs but *who* pays. The apotheosis of a culture built around disposability

Save the date! The @pasteur.fr Pasteur course on image analysis is announced:

It will happen from the 1st of June to the 5th 2026.

This year there will be only one track: the Early Career Investigator track (beginners). ๐Ÿ‘‡

Cherry Ray Tracer

After 1.5 years of tinkering and three rewrites, I'm happy to say that my web-based ray tracer for #optics and lens design has reached a point where I can finally start packing in features and make it *useful.*

Feel free to let me know what you think.
