Mycobacterium tuberculosis overcomes phosphate starvation by extensively remodelling its lipidome with phosphorus-free lipids - Nature Communications Here, the authors show that Mycobacterium tuberculosis manipulates lipid metabolism to overcome host restriction, by remodelling its lipidome and utilising host lipids as an alternative phosphate sour...

We’re excited to share our latest study that reshapes our understanding of Mycobacterium tuberculosis (Mtb) lipid composition, with major implications for drug discovery, immunity, and vaccine development.

A thread.

Excited to see the PhD work led by Sarah Danchuk published today. Virulence hierarchies within the Mycobacterium tuberculosis complex. Thanks to all the authors and collaborators, and especially kudos to Sarah: www.pnas.org/doi/10.1073/...

Quote by Paul Sutter which says "The public needs to see scientists as poeple, rather than simply sources of information"

Given the absolutely insane levels of disinformation and growing attacks on science and scientists, all scientists must be taught

- how to communicate effectively
- how to engage the public
- how to engage politicians and policy makers
- how to engage with the media
- how to counter misinformation

Welcome, Shabaana!

Yes absolutely...we have a follow-up study demonstrating exactly that. Stay tuned

Thank you Steve 🙏

In doing so, this talented young scientist discovered 1) a novel activator of ESX-1 gene transcription and 2) a novel vaccine that is as protective as BCG but does not compromise existing TB diagnostic tests.

Slim Zriba (PhD student) engineered Mycobacterium smegmatis to produce a functional Mtb ESX-1 system.

In this study, we modified Mycobacterium smegmatis, which is often used as a surrogate model organism in mycobacterial research, to produce and assemble a functional Mycobacterium tuberculosis (M. tb)...

My fantastic group threw me a surprise birthday lunch today 🎉 🥳 🪅 Couldn't ask for a better group of people to be my partners in crime in the lab 😁

Corporate administrators who have only experienced jobs whose main benefit was pay cannot fathom that the very best find intrinsic value in excellence and are best left to do it without undue interference or burden

Congratulations!

I got hit by some rather sudden and extreme financial hardship so if anyone is in need of remote wetlab contract research, strictly BSL1, do let me know. Currently scrambling for gigs.

NBC News: A deadly E. coli outbreak hit 15 states, but the FDA chose not to publicize it

Reuters: US FDA suspends food safety quality checks after staff cuts April 17, 2025

These stories landed today, within 11 hours of each other.

This presidential administration is a clear and present danger to the American people.

“Tuberculosis has long suffered a PR problem… We are looking at a world whereby, two years from now, 2 million people will die of #tuberculosis, instead of 1.25 million… This is getting worse, not better, and I really hate it when we have the ability to make something better and we let it get worse”

Tuberculosis Resurgent as Trump Funding Cut Disrupts Treatment Globally The United States was the major funder of tuberculosis programs. Now hundreds of thousands of sick patients can’t find tests or drugs, and risk spreading the disease.

The gutting of USAID has crippled tuberculosis programs, leaving hundreds of thousands of patients without tests or drugs and at risk of spreading the disease.

Amazing thesis work led by Sarah Danchuk now submitted for review and posted as preprint: ssrn.com/abstract=51598…. Short summary: M. bovis & M. orygis manifest enhanced virulence compared to M. tuberculosis in natural host model (calves) and small animal model (mice).

I’ll be in Pittsburgh at the Stand Up For Science March at Schenley Park. 11AM Friday March 7! Come on people! Support the good people who do research to improve and save lives!!

For all of you who cannot access pubmed, here is a good alternative:
europepmc.org

Remember, EuropePMC is actually better than #PubMed because it includes ALL preprints in search results, not just those including NIH-funded research.
