Science sleuths say the doctored Western blots uncovered so far are likely the ‘tip of the iceberg’ and greater transparency & accountability is needed moving forward. @elisabethbik.bsky.social @reeserichardson.bsky.social @sholtodavid.bsky.social www.chemistryworld.com/news/thermo-...

Our latest paper is out, looks at hormones in Alzheimer's Disease please see as open access publication link.springer.com/article/10.1...

Integrated epidemiology and toxicology reveals the protective effects of TMAO against chemical neurotoxicity in children https://www.medrxiv.org/content/10.64898/2026.07.02.26357012v1

TMAO is a major component of fish. It protected against effects of mercury (a common environmental contaminant of fish) in our in vitro model. /5

In a 3D in vitro human cell model, TMAO activated synaptogenesis-related gene expression. /4

Cohort study of childhood mental health (N=1,203) - TMAO was associated with fewer internalising problems. Its precursor microbial metabolite trimethylamine was associated with more behavioural problems in the cohort and an independent longitudinal study from 1-15 years of age (N=630-820). /3

Our previous work showed that TMAO supplementation protects the blood-brain barrier in vitro (human cells) and barrier function and cognition in vivo (mice). Here we show the positive neural effects of TMAO extend to humans. /2

Our new findings emphasise the importance of interdisciplinary approaches to evaluate associations and potential pathways of microbiota-host co-metabolites (endogenous) and environmental (exogenous) metabolites on neurodevelopment in #exposome studies. #microbiome #gutbrainaxis

Excited to share the latest one from the lab led by José Solano @jolusolo.bsky.social who explored how early life #stress impacts the mouse 🐭 brain 🧠 vasculature Science 🧪🔬 can be surprising & 2x stress can induce beneficial adaptations leading to resilience, phew! www.biorxiv.org/content/10.6...

New findings indicate that blood markers linked to gut bacteria may help identify early cognitive decline, potentially enabling earlier detection of dementia before symptoms appear. doi.org/hbvkm7

Excited to present our latest paper, led by @dvauzour.bsky.social and Dr Emily Connell. We have promising data showing that a pattern of microbe-derived metabolites can distinguish early stage cognitive impairment in humans. doi.org/10.1080/19490976.2026.2649487 🧪🧠🦠 #microbiome #gutbrainaxis

Key takeaway: 🧠 Shifts in “good” vs “toxic” metabolites may signal early disease risk 🧪 Machine learning identified a 6-metabolite signature 🔬 Potential pathway toward non-invasive screening tools @ueamedical.bsky.social @uniofeastanglia.bsky.social @ukgibanetwork.bsky.social

What if a simple blood test could help detect early cognitive decline? Our latest study shows that microbe-derived metabolites shaped by the gut microbiome can distinguish early-stage cognitive impairment with promising accuracy.

I wrote about the recent autism-microbiome paper, why I think it's the most important microbiome paper this year, and what it says about the field open.substack.com/pub/blekhman...

You're a parasitic ant queen eyeing the colony of another species. You have a simple plan: 1. Hide your scent by rubbing workers on your body 2. Infiltrate the nest 3. Spray the queen with chemicals that goad her daughters into tearing her to bits 4. All hail the usurper! (my latest for CNN) 🧪

Wow 'MHRA-led study reveals major inconsistencies in global microbiome research' www.gov.uk/government/n... 'Species identification varied from 63% to 100% accuracy across different methods, meaning that some laboratories failed to detect a third of the bacterial species present in the sample'

I came to this country as a child refugee. No English, no certainty, no idea what my life could become. Britain gave me refuge. Not on a timer, not with conditions attached, but with a chance to grow roots. A thread 🧵 1/8 www.bbc.co.uk/news/article...

Claims that autism could be caused by problems with the gut microbiome have caught media attention but some microbiologists are sceptical trib.al/fgv5oLv

The link between the gut #microbiome and autism is not backed by science, researchers say. Read the full opinion piece in @cp-neuron.bsky.social: spkl.io/63322AbxpA#microbiome @wiringthebrain.bsky.social, @statsepi.bsky.social, & @deevybee.bsky.social
