I think this is one of the finest essays we've ever published at
@asimovpress.bsky.social

It tells the entire story of a liver transplant, without sparing any detail. Every cut, every incision...the race to the next hospital...

I learned a ton. Highly recommend Donna Vatnick's article.

Asimov Press @asimovpress.bsky.social · 2d

Writer Donna Vatnick spent dozens of hours observing a liver transplant.

She watched as surgeons extracted an organ from a dead donor, placed it on ice, flew it to another hospital, and transplanted it into the recipient.

The full story, told in intricate detail, is out now:

Seeing Microbes from the Sky

Biotechnology needs more and better transducers.

Niko McCarty @nikomccarty.bsky.social · 13d

Hyperspectral cameras, mounted to drones, can be used to see microbes from > 90 meters away. It's now possible to monitor microbes across entire ecosystems.

My new Asimov Press essay explains how it works & regulations on releasing genetically-engineered microbes into the wild.

Today we are launching Issue 08 of @AsimovPress.

There will be at least 2x new articles each week for the next two months (and...a podcast?)

Coming up:
- A deep history of electron microscopy.
- How to see microbes from the sky.
- Making computers smell.

... and much more.

Asimov Press party // September 30 // Boston // Asimov HQ

There will be trivia. There will be winners (and losers). And there will be prizes.

Come celebrate, answer questions, and show everyone how much esoteric biology stuff you know. Hope to see you there!

Out today: A useful review on AI-designed protein binders.

It covers the history of this work + has lots of good case studies, including how these tools are being used to make snake anti-venoms.

The tables are particularly valuable.

E. coli copies 600 bases of DNA/second.

It makes one error every few billion bases, or one mutation per 1,000 generations.

I made an animation to show just how crazy this is. Every green square is a copied nucleotide. The red squares (very rare) are mutations. 🔻

Behold the cursed noodles.

Researchers mixed together chicken muscle cells and microalgal cells, and then extruded them with a 3D printer, to make a "plant and animal cell-based hybrid noodle."

The reason for doing this, they say, is to tune textures, nutrition levels, etc.

Cable bacteria link together (thousands of cells, end-to-end) to conduct electrons across distances up to 7 centimeters. They are living batteries.

They were discovered in Aarhus, Denmark in 2012. I visited Aarhus last year to see them in person, and wrote about it today.

In situ structure of a bacterial flagellar motor at subnanometre resolution reveals adaptations for increased torque

Nature Microbiology - In situ cryoEM and modelling of the Campylobacter jejuni flagellar motor characterize the periplasmic scaffold and the structural basis for increased torque generation.

The flagellum motor is biological design of the highest order.

The motor hits rotational speeds >1,000 rpm. The basal disk (that purple ring) alone is built from 51 tethered subunits. The tail whips at high torques thanks to interlocking cogs, an axial driveshaft, and propeller.

Using E. coli to convert post-consumer PET plastic into acetaminophen.

The researchers discovered a biocompatible Lossen rearrangement; it uses phosphate as a catalyst.

They start the Lossen rearrangement in phosphate buffer and add E. coli; PET to acetaminophen at 92% yield.

YouTube channel idea: Recreating famous biology experiments.

Explain what was known at the time, go through the initial observations, and make the "discovery."

e.g. Monod's biphasic E. coli growth curves, T.H. Morgan's fly breeding programs, and so on.

It's sad, in a way, that a magazine spending $4M a year to hire additional, talented writers is seen as "throwing a lot of money."

It's good that The Atlantic is spending more money on writers. It is the anti-status quo. May their poaching drive up salaries elsewhere, too.
