Excellent opinion piece by @eschonquinlivan.bsky.social in today's Irish Examiner about the current situation in France, linked to the presidential prospects of Marine Le Pen 🇨🇵. www.irishexaminer.com/opinion/comm... @ucc.ie @joh2024.bsky.social @jfcryan.bsky.social @irishexaminer.bsky.social

Gut Microbiota for Health
@gmfhx.bsky.social

Could coffee influence the gut microbiome beyond caffeine? ☕🦠 Prof. @jfcryan.bsky.social discusses how coffee polyphenols may shape microbial communities involved in gut-brain communication, and what recent findings reveal about regular and decaffeinated coffee.

shorturl.at“The benefits of coffee may have more to do with microbes than caffeine"Speaking during a visit to Barcelona, Professor John Cryan discusses new findings showing that coffee polyphenols may support microbial communities involved in gut-brain communication—and why decaffeinated coffee produced similar effects.

The herbicide glyphosate disrupts behavior through microbiota-gut-brain axis New findings in mice from @jfcryan.bsky.social et al. validate the concept of ecological psychiatry and strengthen the glyphosate-remodeled microbiota in modifying social behavior:

In the harsh environment of Canada’s Sable Island, any slight advantage may make the difference between life and death. Now, researchers have found how some horses eke out an evolutionary edge: the microbes living in their guts. Learn more: https://scim.ag/3Sxk1SO

Gut Microbiota for Health
@gmfhx.bsky.social

One of the biggest obstacles facing microbiome and mental health research is a lack of global diversity in the people studied @jfcryan.bsky.social et al. contend that the field has become overwhelmingly concentrated in wealthy nations, limiting scientific discovery

tinyurl.comGlobal mental health benefits from expanding microbiome–gut–brain axis research to the global south - Nature Mental HealthThis Perspective emphasizes the necessity of expanding microbiome–gut–brain axis studies into low- and middle-income countries, highlighting potential insights into mental health and environmental interactions, while addressing ethical responsibilities and the need for diverse global health interventions.

Forever chemicals, the microbiome, and brain health: towards therapeutics

dlvr.itForever chemicals, the microbiome, and brain health: towards therapeuticsPer- and polyfluoroalkyl substances (PFAS) are persistent xenobiotics linked to neurodevelopmental, neurodegenerative, and neurological disorders. PFAS-induced gut microbiota remodelling may disrupt gut-brain signalling, thereby affecting brain functions and behaviour. Integrating microbiome endpoints (diversity, taxonomic shifts, and metabolic configuration) into PFAS research provides a framework to elucidate toxicodynamic mechanisms and to inform the development of targeted, mechanism-based therapeutic strategies.

A team from University College Cork has published an innovative study whose results, while subtle, reaffirm that #pesticides, and #glyphosate in particular, affect #behaviors in mice that are important for social relations, learning, and reproduction. ➡️ Daily News: https://ow.ly/8ZqQ50ZoYAG

ow.lyEcological Psychiatry Study Explains Pesticide Induced Behavioral Changes to the Gut Microbiome-Brain Axis - Beyond Pesticides Daily News Blog(Beyond Pesticides, July 17, 2026) It is now well established that frequent exchange of signaling between the brain and the gut is a crucial feature of human mental and physical health. External chemicals introduced through the digestive system affect the gut microbiome, which in turn influences the brain. Perhaps the most ubiquitous and pernicious bad actor in the large cast of pesticides shown to disrupt the gut-brain axis is the weed killer glyphosate.
