Global topsoil contains ~110 quadrillion km of fungal threads, roughly one billion times the distance from the Earth to the Sun. A new study in @science.org maps this hidden arbuscular mycorrhizal infrastructure for the first time. Explore the Mycorrhizal Infrastructure Map: buff.ly/PISOj8k

A hidden infrastructure

Mapping Earth’s underground mycorrhizal fungal networks — the hidden infrastructure beneath our feet.

Right on time for #GSB2026, soil fauna made it to the cover of Nat Eco Evo (great shot by frankashwood.bsky.social). Attendees who have questions on the journal or papers to pitch, feel free to chat to me at the conference. @thegsbi.bsky.social

Our April issue is now live! www.nature.com/natecolevol/... Featuring research on: 🦑 squid and cuttlefish diversification 🌊 priority questions for blue carbon science 🐦‍⬛ the emergence of Usutu virus Cover image from Zhou et al (credit @frankashwood.bsky.social ) www.nature.com/articles/s41...

Cover image for the April 2026 issue of Nature Ecology & Evolution. The image shows a close-up image of a black and orange collembolan foraging in soil. The headline reads "Soil trophic diversity".

ust got accepted my 80 peer-reviewed article: “Migration should be a personal choice, not the only one – a reflection on scientific diasporas” on Research Ideas and Outcomes. There we discuss how to get to a functional scientific diaspora.

Thanks for the nice invite. Had a wonderful time in Bochum learning a lot about Diversity in all dimensions and areas! Now in Berlin some few days.

Sessions two and three also with very interesting talks on diverse topics (pun intended!): From endometriosis (@acfischer.bsky.social) and hormone research (@sophiawagemann.bsky.social) to soil biodiversity (@cmarin.bsky.social) and bio-social diversity in the Amazon region (@rbsuchoa.bsky.social).

Ann-Christin next to her title slide before her talk on endometriosis patients as epistemic agents.

Constanza is my third bachelor thesis student who finished her thesis with the highest grade possible and with a WoS paper published before finishing. Cherry on the cake: already with a permanent job. Couldnt be more proud!

3 great news: - We have started our SOCBIO-MAP project fund. by European Space Agency. - Tomorrow a very nice paper in collab/funded by SPUN will appear in Biod. Conserv. We now know about the mycorrhizas of one of the oldest trees in 🌍 - Ill give a talk in Harvard on Wednesday

A study in Nature shows that the single-celled form of a tiny, aquatic organism can turn into a multicellular version by three different routes. The discovery adds insight to the possible origins of multicellular life, suggesting a previously unrecognized degree of flexibility. 🧪

Clonal-aggregative multicellularity tuned by salinity in a choanoflagellate - Nature

The choanoflagellate Choanoeca flexa forms motile and contractile cell monolayers purely clonally, purely aggregatively or through a combination of both processes depending on environmental conditions.
