I really enjoyed taking part in the @shushradio.bsky.social Takeover at @ucc.ie where I had the chance to choose a few favourite songs and talk about the importance of libraries in research and innovation.

Thanks @martinoconnor.bsky.social for expert hosting

An unhealthy diet disrupts feeding behavior and the gut microbiota, but whether early-life dietary effects persist, or can be restored later in life, remains unclear. We investigated whether microbiota-targeted interventions (FOS + GOS or Bifidobacterium longum APC1472) could restore early-life highfat/ high-sugar (HFHS) diet-induced feeding alterations in adult female and male mice.

New APC paper in Nature Comms
First author Cristina Cuesta-Marti and colleagues examine how eating unhealthy foods early in life leaves lasting brain and feeding changes but bacteria can help restore healthy eating.
