Promotional graphic for a special issue of Disease Models & Mechanisms titled "In Vitro Models of Human Disease to Inform Mechanism and Drug Discovery." The left side of the image contains text announcing the call for papers, edited by Vivian Li, Austin Smith, and Joseph Wu, with a submission deadline of 3 November 2025. The right side features a vibrant, microscopic image of biological tissue or cell structures in vivid pink, blue, and yellow hues, representing the complexity of in vitro disease models. The design combines scientific detail with visual appeal to attract submissions for the issue.

This week I have submitted my tenure packet, proposal (NIH resubmission), and a manuscript (for review)

The holographic doctor tells me that I may be experiencing some elevated fatigue and should better take care of my sleep schedule."

But yes to productive week!!

For last 10 years - we have worked with thousands of organizations around the world helping support them in integrating foldscope programs.

To bring in a new cohort of organizations - we are re-launching β€œfast and curious” 2025 edition - apply and get a Foldscope trainer and Foldscopes for free!

Photo of square orange tiles, set into the ground, across one of which several cats footprints are clearly visible.

One day, nearly 2000 years ago, a cat dashed across some drying tiles, somewhere near Hadrian's Wall.

It's immortality of a kind, isn't it?

2 main take aways
(A) Hydra - vulgaris specifically is really great at surface attachment.

(B) At high volumetric flow rates (high shear) polyps (again vulgaris in particular) aligns with the flow direction.

Our prototype Disintegration Fingerprinting apparatus. (A) A servo drops a single pill into a water-filled cup atop a magnetic stirrer. The pill begins to disintegrate into particles (B), and an infrared optical sensor on the side of the cup detects the light reflected by individual particles as they pass the sensor (C). As the particles disintegrate and dissolve further, the number of particles detected changes (D). A plot of peak count vs. time (E) serves as a β€œDisintegration Fingerprint” for this pill.

I really think we need (physical) thank you or congrats notes to send all the researchers - specifically for folks early in their research careers (for example grad students).

We have been talking about a way to do this (communications) activity in a course. But haven't fully figured it out yet.

Back of postcard with university address.

Here's a fun bit of science history for you: Back before we could just download PDFs, if you wanted a paper and it wasn't in a journal in your library, you wrote to the author for a copy.

So universities made these nice little post cards for requesting article reprints.

A Bar plot.  
It shows 2/3 of cats studied sleep leftward.  The remaining sleep rightward. 

The plot has photos of two cats sleeping (one leftward, the other rightward) under each chart to demonstrate their results. 

Both cats look comfortable - deep in sleep.

One of the most fun papers (brief) I have read this year

Cats prefer to sleep on their left side.
Also they sleep 12-16 hrs/day.
