Professor of gut microbiology. Allegedly grumpy, but actually just Scottish. Messages/rants are my own views, not the University's, obviously.

I still contend that >90% of the benefit of writing a review isn't the audience. It's for the author going through the literature, finding gaps in knowledge, learning how experiments are done, etc. It really isn't about writing a review. It's about doing the review yourself. AI can't do that for you

Excellent article on quantitative production of fermentation products by the microbiota. Key takeaway: microbial fermentation products may be more important in mice than humans, amplifying microbiome effects in mice. www.cell.com/cell/fulltex...
Quantifying the varying harvest of fermentation products from the human gut microbiota
Fermentation products are the most abundant gut microbial metabolites absorbed by the host, with important dose-dependent consequences for health. In this study, we present a systems-level analysis in...

The landscape of microbial associations in human cancer www.science.org/doi/10.1126/...

TLDR -- most cancers do not have microbiomes...but a few do have consistent microbe associations (i.e., colorectal and oral cancers). Make sense!
The landscape of microbial associations in human cancer
Differences between cancer types, infectious disease, and potential prognostic markers are uncovered by studying microbes within cancer DNA.

Brain microbiome: is it all in our heads?
In their September 2018 Editorial, The Lancet Infectious Diseases discussed the over-reaching inferences leading to suggestions of a placental microbiome, and touched on how the same extrapolations we...

Frustrating - I reviewed a paper that was highly problematic, mainly in scientific rigour undermining most of the conclusions, so I recommend Reject. However the editor decides to Revise presumably due to the more positive comments from reviewer 2... /1

Abigail was just the greatest. I miss her.
To honour Abigail A. Salyers (1942-2013), who is considered as the mother of microbiome research, DSMZ researchers named the strain Streptomyces salyersiae (DSM 41770) after her.

Paperboy, turnstile operator, shelf stacker, pipe grinder, pet shop boy, rose breeder, field hand, warehouse dispatcher, and medical laboratory scientific officer (trainee). And I gave it all up for a life of studying poop. It's a strange universe.

- Farm hand (fencing, thistle cutting, scrub cutting, mustering)
- Forestry work (pruning, donkey)

After editing, this very short letter to New Scientist is even shorter now. But I think it gets the point across! @faecalmatters.bsky.social

For anyone interested, The Microbiologist has published a couple of short articles summarising a nice recent chat I had with Yang Yue from UEA, including some musings on microbiome research, and networking/public engagement opportunities for ECRs:
