Unfalsifiable by Design: A Year of Trying and Failing to Reproduce a Human Microbiome and Autism Study The myth of open data, reproducibility, responsibility, and accountability in science, and your role in it

How every layer of science's "self-correcting machinery" failed when Iva Veseli and I simply wanted to reproduce the findings of a high-profile study on gut microbiome and autism:

Requested change: Please reduce the scope to match the normal level of free time.
Review: Impressive commitment to a bit nobody asked to be taken this far.
Comment: Implementation exceeds expected effort in ways that raise questions about available bandwidth.

Phage receptor prediction from genome sequencing alone. Bacterial receptor (blue) interacting with phage proteins (purple) is shown here

Phage receptor prediction from genome sequencing alone. Bacterial receptor (blue) interacting with phage proteins (purple) is shown here

📣Huge preprint 🔔
Today we share something our group has been working toward for a long time, led by @lucasmoriniere.bsky.social We asked can we predict which receptor a phage targets from its genome sequence alone? For most phages, we couldn’t. So Lucas set out to do something I had only dreamed of.

A virus hiding inside bacteria may help explain colorectal cancer Scientists found an unexpected viral hitchhiker lurking inside a common gut bacterium – and it was twice as prevalent in people with colorectal cancer.

The mood stabilizer lithium alters behaviour and physiology via the gut brain axis. Lithium, introduced 75 years ago by John Cade1, remains the most effective mood stabilizer for bipolar disorder2. Lithium is proposed to modulate an array of cellular pathways, many ubiquitous to all cells, with pleiotropic roles unlinked to bipolar disorder or lithium responsiveness in genome wide association studies3,4. These mechanisms cannot explain lithium's specific effects on mood and behaviour. We demonstrate that lithium's primary action is in the periphery, not in the brain itself. Lithium acts in the gut to trigger behavioural and physiological changes, akin to those associated with a torpor-like state, that protect individuals from ingested toxins. Lithium activates gastrointestinal enterochromaffin (EC) cells via their Trpm2 cation channels to modulate afferent vagal and area postrema inputs to the brain. Eliminating these inputs by focal brain lesions eliminates lithium's effects, as does ablation of EC cells or their Trpm2 expression. Lithium's Trpm2-dependent activation of EC cells also occurs in human gut tissue, providing translational relevance for our discovery. These findings challenge the prevailing perception that lithium acts directly on the brain. Via a previously unsuspected gut-brain pathway, lithium engages brain circuitry that reduces arousal and interaction with the external world, therapeutic goals in the manic phase of bipolar disorder. ### Competing Interest Statement The authors have declared no competing interest. National Health and Medical Research Council, https://ror.org/011kf5r70 Baszucki Brain Research Fund

#Lithium doesn’t act directly on the brain. Instead, it signals via the gut–brain axis, acts on EC cells, engages TRPM2 and vagal pathways. Our team found a mechanism with major implications for #psychiatry and #bipolar disorder
