Microbiomes are the foundation of the biosphere. Hosts such as humans, bees, and plants have never been just hosts. They are complex units of biological organization upon which various forces act to shape composition, form, and function. www.science.org/doi/10.1126/...

Our education partners of the Wolbachia Project bring real-world biotech to high school students worldwide. The donation of a testimonial is worth a lion's share of reward. ⬇️
It’s Giving Week!

Today we’re highlighting The Wolbachia Project, an education initiative bringing real microbiome + biotech research into classrooms.

From 2022–2025, it’s partnered with ~400 teachers and ~20,000 students globally. 🌍

Petrosiidae sponges were collected by submersible, dredging, or snorkeling from the Caribbean Region, Red Sea, and Indo-Pacific Region. Sample sites spanned marine caves, coral reefs, mangroves, etc. #Phylosymbisosis exists in several pockets of the tree.

Starting this week, I set aside one hour each week to meet ECRs outside my group who want to discuss career development, mentorship, or any non-technical professional questions.

Invaluable moments spent with the Curtis Huttenhower and @psumbiome.bsky.social this week, solidifying collaborative paths over Brazilian dinner (priorities) and One Health Microbiome Science. Curtis charts the microbiome and virome maps for many. Hat tip to @erika-ganda.bsky.social for commanding.

NSF is open again!

A few comments:

*Please be patient.
During a shutdown NSF employees cannot open computers or respond to emails.

*Merit review will continue. However panels won’t resume until after Dec 8th.

*POs remain excited and committed to advancing science and the scientific workforce.

A few weeks ago, I got to hike the Vallunga Trail in the Italian dolomites with my friend and colleague @momedinamunoz.bsky.social. It’s a 6 mile valley hike with autumn peak foliage in an area that escaped most of the tourists. Locals were trailing with their kids and cameras. Still soaking it in.

Paradoxical role of new endosymbiotic associations: they facilitate the emergence of new partnerships, but inhibit deeper integration between hosts and guests (by favoring uncoordinated reproduction over synchronized ones). That is, easy come, easy go. #Endosymbiosis doi.org/10.1101/2025...
