Monkey auditory neurons "did not show enhanced responses to unexpected stimulus repetitions, contrary to predictive-coding theory. However, they did show enhanced responses to unexpected stimulus omissions." www.biorxiv.org/content/10.6...

It's out! Happy to present ITEC, a semi supervised algorithm with an extremely low error rate that can track cells in files of any size (think Terabytes!). We used it in many organisms, including zebrafish, to study how organs form and linked it to gene expression www.biorxiv.org/content/10.6... +🧪

Loss of Fsr quorum sensing promotes biofilm formation and worsens outcomes in enterococcal infective endocarditis - Nature Communications Infective endocarditis (IE) is an understudied biofilm-associated infection. Here, analyses of preclinical and clinical data reveal that the Fsr quorum sensing (QS) system of Enterococcus faecalis is ...

What if quorum sensing doesn’t promote biofilms - but restrains it? 🤔

New work from @harisantypas.bsky.social shows that the Fsr QS system in Enterococcus faecalis acts as a brake on biofilm formation and pathogenesis during infective endocarditis (IE).

YES, HOW IS THAT NEWS TO YOU?

Yeah, not very surprising, in the thread Anthropic had the same results. So maybe we should stop pushing AI everywhere?

Intestinal macrophages modulate synucleinopathy along the gut–brain axis - Nature Muscularis macrophages, housekeepers of enteric nervous system integrity and intestinal homeostasis, modulate α-synuclein pathology and neurodegeneration in models of Parkinson’s disease, and understanding the accompanying mechanisms could pave the way for early-stage biomarkers.

Eighty-one years ago today, over 7,000 prisoners of the German Nazi camp #Auschwitz, including some 700 children, were liberated by the soldiers of the Soviet Army.

1,689 days of murder, pain, suffering, and humiliation were over.
Today, we all remember. We must keep remembering.

Today marks 81 years since the liberation of Auschwitz.

We must never forget the horrors of the Holocaust.

Keystone concept revisited: insights into microbial community dynamics and control Nature Reviews Microbiology, Published online: 02 January 2026; doi:10.1038/s41579-025-01266-8In this Perspective, Garza et al. revisit the keystone concept and discuss its relevance for microbial keystone taxa and functions. For this, they explore the different mechanisms behind keystoneness, cover the strengths and weaknesses of current keystone prediction methods, present recent findings on keystone taxa and functions and explore the role of keystones in community control.

New online! Keystone concept revisited: insights into microbial community dynamics and control

I will be recruiting two postdocs early next year.
- One image analyst
- one biologist interested in working on lymphatics!

Reach out if you are interested 👍

A super detailed protocol + video on Cryo-ExM - Cryo-Expansion Microscopy, led by the labs of our former postdocs @marinelap.bsky.social & @ebertiaux.bsky.social.
Clear, practical, and very useful for anyone doing nanoscale imaging 🚀 app.jove.com/t/68595/expa...

The Center is a wonderful collaboration with scientists extraordinaire @taijamakinenlab.bsky.social Kari Vaahtomeri and Cecilia Sahlgren.

We are all recruiting, so keep an eye on our website If you are looking for a postdoc position 😀

Point of no returns: researchers are crossing a threshold in the fight for funding With so little money to go round, the costs of competing for grants can exceed what the grants are worth. When that happens, nobody wins.

"How can funders avoid crossing the Szilard point?"

The Szilard point is "the threshold at which the total cost of competing for a grant equals (or surpasses) the value of the available funding."

The Microflora Danica atlas of Danish environmental microbiomes - Nature Microflora Danica—an atlas of Danish environmental microbiomes—reveals that although human-disturbed habitats have high alpha diversity, species reoccur, revealing hidden homogeneity.

Denmark just mapped its entire environmental microbiome. More than 10,000 samples revealing hidden, dominant nitrifiers that shape fertilizer use, water quality, and climate impact. A national microbiome atlas could transform sustainable agriculture across Europe.
