(1/n) DNA-PAINT imaging inside the nucleus at single antibody resolution using TIRF? Ultrathin sectioning makes it happen!

Grateful to share my postdoctoral work introducing “tomographic & kinetically-enhanced DNA-PAINT” or in brief: tkPAINT. Out in @pnas.org!

I fear there is deep truth here.

Still our favorite #review! Unfortunately, as relevant today as when it was published, it is an excellent illustration of the #problems arising from the neglect of #ultrastructure and #electronmicroscopy in #cell-biology and the over-reliance on #fluorescence #microscopy.

Goldman Sachs asks in biotech research report: 'Is curing patients a sustainable business model?' Goldman Sachs warns sales from the most successful disease treatments are difficult to maintain.

We possess the technology to create products that nearly never break. We were doing it in the 70's & 80's.

Then came 'planned obsolescence' - intentionally designing products to become obsolete or break quickly within a set time frame.

This is that- but in reverse.

At my institution, they want to install profiles on our personal phones that will give IT root level access to our personal phones.

And allow them to remotely wipe our phones. Our personal phones.

Damn straight, take your work email off your phone. And remove your work profiles from your phones.

Instead of listing my publications, as the year draws to an end, I want to shine the spotlight on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.

What Makes a Tick Stick? Ticks form a stable structure around their mouth to stick to their hosts for days. Phase transitions of proteins in the tick saliva drive this adhesion.

This is fascinating! Ticks form a "cement cone" from their saliva that glues them to you. Now we know more about the chemistry of that bioadhesive process 🧪 www.the-scientist.com/what-makes-a...

An image from the now retracted paper, Figure 6B. It shows ten black and white microscopy photos, organized in two rows labeled Mock and si321+si359 and five columns labeled #1 through #5. I have marked three of the boxes with red, green and yellow boxes, showing unexpected overlaps.

This lab @tulanemedicine.bsky.social has 23 papers with @pubpeer.com comments and 7 retractions.
Yet, the Principal Investigator is still a professor at Tulane.
Is Tulane looking the other way, as long as the PI brings in the grants?

I'm gonna piss a few nerds off but this is an example of why a lightsheet microscope should be used to study organoids. The detection optics are great for imaging in XY but they suck axially. Sure, yeah, hocus pocus, RI matching, correction collar, blah blah, but it's physics, baby.

The main body of the parasitic copepod that houses the reproductive and digestive organs. In this stage of its lifecycle, it has lost its limbs and antennae

Here’s another very interesting and common marine organism. They’re copepods, albeit, they look almost nothing like typical free-living copepods you may know.

This group starts as juveniles looking like most other copepods, but lose their limbs and antennae once they mature.
