Faculty search announcement 2026: Tenure-Track Assistant Professor in Microbiology at UT Southwestern in Dallas. We seek candidates working in microbial pathogenesis (broadly defined). Come join our community! (1/5) www.utsouthwestern.edu/departments/...

I said it before, I say it again: get an MMR titer at your next physical. You want antibodies when measles virus comes your way. I got mine, and I still have immunity.

Cool Myosin zipper! Imaged on our omniOPM system. #FlourescenceFriday

Saw a Cybercab out of my Waymo ride. #Singularity

@grimmrad.bsky.social : Expensive mishap for Lufthansa…😞 www.reddit.com/r/Lufthansa/...

I think we have some work to do…

Hello #world, meet 1,000× Expansion Microscopy. A small gel would grow to the size of an Olympic swimming pool, while amino-acid-scale distances become visible with ordinary light microscopy. Led by Helena Hu from @eboyden3.bsky.social's lab, in collab with us. Story: www.biorxiv.org/content/10.6...

An internal model from OpenAI disproves a conjecture by Paul Erdös, and eminent mathematicians confirmed the correctness: cdn.openai.com/pdf/74c24085... Can any math adjacent folks on bluesky chime in on this? Watershed moment, or low hanging fruit for AI?

Prof Jonathan Taylor of @uofgphysastro.bsky.social is leading a £4m new project with colleagues from @imperialcollegeldn.bsky.social and @sheffielduni.bsky.social to create detailed 3D images of the mechanical forces inside a living, beating heart. Read more here: www.gla.ac.uk/news/headlin...

Of all the books banned in Utah, „Mein Kampf“ is not one…

We got multiple times the feedback that oblique plane microscopes are too complex. So how about a detection train with only two photographic lenses? www.biorxiv.org/content/10.6...

If you’re waiting for dichroic mirrors, I have bad news for you:

Cleaning microscope optics can be tedious. But compare it to this job😳:

22 pilots or just keep incrementing: pilots = pilots++

Hi optics folks We have a couple of fixed output CW laser. Is there something easier for power modulation than Acousto-optical filters? 10-100kHz modulation rate would be enough. Single mode fiber coupling is also fine. Electro optics, Mems fiber switch? @tanner-fadero.bsky.social

Back from @aqlm.bsky.social . Adequate sunset view on the way back.

@rtomer.bsky.social : Pizza time at AQLM! @aqlm.bsky.social !

@aqlm.bsky.social Quite reasonable requests…

Calm before the STORM. #AQLM

Magnetically controlled luminescence. Andrew York strikes again!

UT Southwestern is quite a food desert, so I take today’s buffet: Very mildly spiced Chicken Vindaloo and not a number bread.

Dramatic cloud formation 😳!

Somebody had a good start into the week😳. UT Southwestern Medical Center, North campus.

On the plus side, both the AI model and the human got to hallucinate a bit.

What do you call a young mathematician interested in properties of geometric objects? Topo Chico / Chica #math

I'm moving to Purdue University as a tenured professor this summer! Excited to hire postdocs there and get a lab up and running with @runxishen.bsky.social as co-lead. More details: www.linkedin.com/posts/anneca...

We offer a PostDoc position for a fully funded project on lipid-encoded #lipidtime protein quality-control checkpoints at the Golgi: great collaborators, excellent working & living conditions & benchspace with a view ;) Please share and repost!

As a remote focus fan this makes me happy. Our little girls also like the Crazy Frog.

Superb job opening: Head PSI Center for Photon Science (CPS) I visited the synchrotron at PSI some 15 years ago. Top research center.

#FOM2026 On top of the dichroic Tower.

#FOM2026 SciLife satellite meeting for those who had not had enough microscopy already. Top microscope development by the bright STARSS in Ilaria‘s lab🤩.

#FOM2026 The Alexander(a) twin problem in holography.

#FOM2026 Damn Skippy! 🤯

#FOM2026 Dichroic tower!

For many labs this also means firing yourself… The US soft money academia model requires that you provide grant funding to pay your own salary and „rent“ for lab and office space.

Be my colleague! :)

🚨New paper out today in @acs.org ACS Nano, showing how expansion microscopy can visually quantify the cell surface receptor turnover mediated by signalling & receptor organising machineries on the surfaces of endosomes, some of the smallest organelles in cells. 🧪 🔬 1/ pubs.acs.org/doi/10.1021/...

I think I saw a Alenia HC-27J Spartan this morning, heading to Love Field. Cute turboprop cargo plane, and aerobatic😳. cc @bwjones.bsky.social

Now we are talking business… #3Dprinting

I have once worked with single digit femtosecond (1e-15s) laser pulses. So how short is a femtosecond? We can use the identity “time is money”. Assuming the entire U.S. debt of $3.89 e13 equals to one second, then one femtosecond would be ~4 cents! In 2008, a femtosecond was only 1 cent.

Breaking news: Laika got the FIFA 2026 Fido award!

Go big or go home😳 arxiv.org/abs/2603.05122 Boldest first line in an abstract. #Math

When I was walking the dog, a lady in a car stopped and asked me what the crazy thing in the sky was, and if I thought too that it was “falling down”. It was a contrail from an aircraft. This was my first real life encounter with a chemtrail person.😞

Still a bucket list thing to do: measure gravitational time relation. arxiv.org/abs/1710.07381

Happy Birthday Paulie! youtu.be/ncySiTOMAHc

Got my first colonoscopy today. My mantra is: cancer types you can visually see need to be monitored and anything suspicious needs to go. If you are in your forties, please consider scheduling yours. #SayNoToColoRectalCancer

If your imaging system has poorly characterized constant distortions leading to chromatic aberration, shoddy stitching, or false measurements (the answer is likely yes), you may want to give this tool a try. Native installers for Linux, Mac, Win under Releases github.com/saalfeldlab/...

The perfect door sign does not exi…

Expansion microscopy gone too far: look at those big spines!

Saw this car this morning at Starbucks. My guess it cost more than a Ti:Sapph laser. Still prefer an ultrafast laser over a sports car😀. cc @bwjones.bsky.social
