Good point, we did not do this though I do remember discussing it at some point. I can't recall why not, or if it was attempted and abandoned for this project. This would be better to ask our MD collaborators (Chen & Vangaveti labs) who did the modeling. Thanks for your interest in the work :)

This approach definitely got me through grad school. If I did half the stuff I agreed to do I'd still be working on my PhD

NIH grants have been under political scrutiny since early 2025. But what does the screening process actually look like? What is being flagged? I spent a month digging into leaked docs and emails. We've published the 235-word list that are being flagged by an internal AI tool. And so much more. 🧵

Inside the new political screening that’s stalling NIH grants
Mandatory reviews by top health officials and checks for 235 disfavoured terms have left hundreds of vetted grant applications in administrative limbo.

The Thermo Fisher situation keeps getting worse. We've now collected 450+ problematic images presented as verification data in TF's antibody catalog. This includes: 🖌️ Dozens more images with duplications or painting 🖨️ Hundreds of blots that all share the same background (behold slideshow below)

Paying peer reviewers works. Expanded Fast & Fair experiment @biologyopen.bsky.social: • 5.5 vs 37.7 working days to decision with reviews • ~3 vs ~9 reviewer invitations per manuscript • no reduction in editor-assessed review quality • similar acceptance rates www.biorxiv.org/content/10.6...
Scatter plot showing that Fast & Fair peer review reached first decision with reviews much faster than conventional peer review: mean 5.5 versus 37.7 working days. Most Fast & Fair manuscripts met the 7-working-day target, while conventional manuscripts were slower and more variable, up to 116 working days.

It’s truly astonishing to see how comprehensively the US government is tearing down every part of the system that has made it up until now a world-leading power in science, research, and technological development. The entire world will suffer from this wanton destruction.

Of all the harm this administration has done to US science, today's proposed changes to the way federal grants are awarded and administered is the most damaging yet. The text of the federal register document is impenetrably tedious by design, so here's an excellent summary of what it says.

NIH funded peeps: This is insane and coming for us.
For FY 2026 RPPRs:
If there are any publications with a foreign co-author, a statement submitted through the Signing Official (SO) confirming the author will no longer publish or collaborate with the foreign partner is sufficient to show the collaboration has ended. Also indicate that no IDeA money was transferred via subcontract to an institution in a foreign country. This path will minimize delays.For FY2027 RPPRs onward:
Pls are required to submit prior approval requests for any publication co-authored with individual(s) affiliated with a foreign institution(s).
Per NOT-OD-26-026, prior approval requests must be initiated and submitted by a SO for the recipient organization.
In addition to noting the foreign site and the name of the foreign investigator, the prior approval request should provide information about the nature of the research being conducted; why the involvement of the foreign site is necessary; and whether any data will be transferred.

There’s only one correct answer to a request like this and it’s “get fucked.” I realize that most individual investigators are not in a position to respond this way, but isolationism as a condition of funding will destroy US science even faster than a dearth of funding will.

Surprised to discover that Thermo Fisher appears to show a fake western blot for the validation of one of their p53 antibodies. I've added a diagram to show the very similar bands. This does not appear to be one of the "published figures" but their own internal data.

Excited to share our new preprint (www.biorxiv.org/content/10.6...), integrating aptamer based sensing into our DNA nanoswitch platform for protein detection. The project almost died about 4 times, and it's nice to see 10 yrs of back burner simmering coming out fully baked. @arunrichard.bsky.social
Design of a dual detecting DNA nanoswitch where aptamer binding of a protein target causes a loop of a specific size to form.  When read on gel electrophoresis, two proteins can be detected simultaneously, in this case VEGF producing a large loop and thrombin producing a smaller loop.

In August, Jay Bhattacharya said “Training future biomedical scientists” was the 1st priority for his version of NIH. But talk is cheap. Let’s see how JB’s doing. 🤔 NIH supports trainees mostly via fellowship (F), training (T), and career development (K) awards. Here are funding curves for each.🧵

We mostly just got rid of all the stuff we didn’t need from a standard gel setup. Turns out you don’t need >200 mL of running buffer, or >100 V between electrodes, or >$1k to spend on a gel box – you just need a 3D printer and a different design. How satisfying!

With a range of designs, we resolved on/off nanoswitches in ~1 minute at 75 volts or in ~45 minutes at 8 volts. We also showed that we could image the gel with a cell phone camera, LED flashlight, and filter paper...

Ken Halvorsen @halvorsenlab.bsky.social · 27/01/2026
One huge advantage of smaller box is the same voltage gives a larger electric field (closer electrodes), enabling either lower voltage operation or faster separation at the same voltage. 3D printing allowed us to quickly test various inter-electrode distances...

Side note for those interested in electrophoresis – this design is cheap and easy! Prints in <1 hour on a dual-extruder printer for ~30 cents of material (>1000x less than any gel box from lab supply stores). We also printed replacement gel combs which performed identically to the $50+ combs...

Postdoc Lifeng Zhou 3D printed mini boxes and added wire electrodes with early encouraging results that we could eliminate much of the gel apparatus. Later Andrew Hayden found conductive filament, and 3D printed the whole gel box with electrodes. It works as well as our conventional gel system!

Ken Halvorsen @halvorsenlab.bsky.social · 27/01/2026
It started because: 1) we noticed that typical gel equipment was overkill for our application, and 2) we heard criticisms that DNA nanoswitch sensing could never become “point of care” due to reliance on electrophoresis. This combined two passions - design minimalism and proving critics wrong :)

Ken Halvorsen @halvorsenlab.bsky.social · 27/01/2026
This dates to ~2019 - we asked whether we could redesign gel electrophoresis to better suit our DNA nanoswitch sensors (which shift migration based on molecular detection). We ended up with a fully 3D printed mini-gel costing ~30 cents, operable with batteries, and capable of detection in minutes…

suspect a big reason why many academics and others who work in areas where getting facts RIGHT is key are disinterested in using LLMs for research: they’ve tried it, they keep noticing major errors in output, and they conclude that having to verify all that doesn’t actually save them time.

I may be reading this wrong, but there seems to be conflict between the PAR-26-121 instructions and new biosketch instructions. In particular the "contributions to science" which MIRA calls for with citations and new biosketch which doesn't allow citations. Anybody resolved this yet?
