Have said this before in other forms, but will reiterate it here: if you're doing long-form writing of any sort, reading the words aloud into a microphone is a completely unparalleled cheat code. It's free, easy, and so effective it feels like it shouldn't be allowed. I do it in a few stages...

Asgard #archaea: have we found our microbial ancestors?
New review (also for newcomers to the field!) by Christa Schleper and Thiago Rodrigues-Oliveira

Are we falling out of love with nonfiction? In the early 2020s, readers flocked to books to explain political turbulence. But is the world now too grim to read about – and are podcasters taking the place of authors?

my view on this is that publishers should stop it with the 80k wordcount obsession, so many contemporary non-fic books are obviously 40-50k pieces of work stretched to the extent that they become very boring to read - just let people write cheaper, shorter books! www.theguardian.com/books/2025/d...

With Eugene Koonin, we propose a concept of “the selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268

A titan of vaccine development sees his field’s achievements slip away Stanley Plotkin, the 93-year-old "godfather of vaccines," is watching his field’s achievements slip away.

Stanley Plotkin had a major hand in the development of a number of vaccines in use today; he designed the rubella vaccine. He remembers the world before widespread use of vaccines & knows what's coming as vaccine policy is rewritten & vaccine confidence is eroded. www.statnews.com/2026/03/02/s...

As Nigel Farage is now so concerned about the influence of "foreign-born voters" can he finally explain why a Kazakhstan-born billionaire appears to be bankrolling his own political party?

That is sad news - must be well over a decade since I last saw him but a great hospitable character and as you say really an unforgettable person with a huge energy & enthusiasm.

Sad to hear the passing of Jeff Cole. I appreciated the small talks with him during my research stay in Birmingham (in 2004); an unforgettable personality, his passion about microbial biotechnology was adherent

Accessing Underexplored Biosynthetic Potential by Initiation Unit Engineering of Nonribosomal Peptide Synthetases in Proteobacteria Nonribosomal peptide synthetases (NRPSs) represent a valuable yet underexplored resource for producing bioactive natural products. However, most NRPSs remain silenced potentially due to factors such as dysfunction of the initiation unit. The starter condensation (Cs) domain of the initiation unit catalyzes the lipoinitiation of nonribosomal peptides via the incorporation of an N-terminal fatty acyl chain. The concept of initiation unit engineering introduced herein encompasses the replacement of the native initiation unit of NRPSs with a foreign and well-characterized Cs domain-containing initiation unit to activate the NRPS and optimize its expression. This strategy was employed herein to successfully access three of the six previously silent NRPS pathways in Mycetohabitans rhizoxinica HKI 454, a bacterium of the class β-proteobacteria, resulting in the identification of three classes of lipopeptides. This strategy was then extended to access two NRPS pathways in Pseudomonas syringae (γ-proteobacteria) and obtain novel lipopeptides, thereby establishing a feasible complement to existing genome mining strategies for natural product discovery. Furthermore, change of the initiation regions of biosynthetic pathways of nonlipidated chitinimide (β-proteobacteria) and pseudotetraivprolide (γ-proteobacteria) with heterologous Cs-containing initiation units enabled the successful incorporation of fatty acyl chains into the N-terminus of both peptide backbones, launching a workable approach to create artificial lipopeptides. Overall, this study provides a practical strategy for the rational recovery of silent BGCs and introduction of fatty acyl chains into nonribosomal peptides, at least in Proteobacteria, thereby enriching genome mining and combinatorial biosynthesis approaches for accessing the underexplored biosynthetic potential of NRPSs from various bacteria.

How perfect is this

Exam conditions yes but doesn't have to be handwritten if you can get your institution to shell-out for Honorlock(or similar software) to lock down browser.

It surprises me when I notice signs like this in 2026 (and they are still everywhere if you look). You'd think people would scrub away these reminders at the first opportunity, but for some reason that don't / can't.

I've started using gellan gum for environmental isolation of bacteria and it seems superior in every way.

A figure showing the bactericidal activity of isoniazid, ethionamide, and alpibectir–ethionamide over a 7-day period.

Ethionamide has been used to treat tuberculosis for decades, but dose-dependent toxic effects have limited its use. In a new trial, alpibectir enabled the ethionamide dose to be reduced by two thirds. Full trial results: nej.md/46PP9Rn
