"Look for the helpers"
—Mister Rogers

Focus on the good, compassionate people acting during crises rather than fearing the disaster itself to reduce anxiety, inspire hope, and highlight humanity's inherent goodness (even it’s very hard to believe in this).

An exciting new study in PNAS led by postdoc Andrea Unzueta Martinez and Prof. @pgirguis.bsky.social lab shows that oysters coordinate with microbes living inside of them to build their hard shells! A game changer for understanding ocean resilience as waters become more acidic from #climatechange

The Dark Frontier by Jeffrey Marlow: 9780593230183 | PenguinRandomHouse.com: Books An awe-inspiring investigation into the hidden world of the deep sea—the most mysterious, unforgiving environment on Earth—whose secrets can radically revise our understanding of life itself...

Hey guess what - I wrote a book, and it's coming out soon!

The Dark Frontier is about the wonders of the deep sea...and the threats they face. Check it out, and if you're so moved, you can preorder from your favorite purveyor of fine literature 📚❤️

Microbiome research according to Gary Borisy

Some of you may know I simulate a lot of biological systems. And after 15 years of doing this, I can confidently tell you: spatial structure is never irrelevant.

It shapes the frequency of mutants... (Fusco et. al, 2016)

The moment you’ve all been waiting for…

New collaborative paper! ⚡

Hannah Feinsibler et al. show that synthetic FeS, FeNiS, and NiS compounds catalyze H+ and nitrate reduction under hydrothermal-vent–like conditions, supporting mineral precursors to enzymes like hydrogenases and nitrogenases! #astrobiology

The Trump Administration Is Racing to Launch the Deep-Sea Mining Industry, Despite Huge Risks and Broad Opposition This would destroy deep-sea habitats and the ecosystems they support.

The Trump administration wants to open our oceans to a destructive deep sea mining industry that would destroy the sea floor and the ecosystems it supports, causing long-lasting harm to the marine environment.

‘This year nearly broke me as a scientist’ – US researchers reflect on how 2025’s science cuts have changed their lives US science lost a great deal in 2025, including tens of billions of dollars of federal funding, entire research agencies and programs, and a generation of researchers.

Trump and DOGE gutted US science: Scientists from a variety of fields researching anything from chemical hazards, drug addiction, pollution, LBTQ health care & paediatric brain disease report how grants were withdrawn and and they struggle to support students, staff and research 🧪

Lost and Found in Modern Microbiology: An Ethnography of Modern Microbiologists A paper on how microbiologists navigate the tension between reductionism and complexity in their everyday practices, and my 2 cents on it.

New blog post for my microbiologist colleagues:

In which Meren talks about a paper by Valentina Marcheselli on how microbiologists navigate the tension between reductionism and complexity in their everyday practices.

Thinking of all the colleagues and friends I have who are connected to Brown University. What a devastating day for Brown, and for all of us.

Brown University is a beautiful place, where people come to work and learn. I am filled with horror by news of this tragedy.

Here's the most important piece of data (as far as I am concerned). Comparing Earth Microbiome to the new ones (V4EXT) for major phyla. V4EXT by @ppjevac.bsky.social et al cover more diversity than current gold standard😱 Lot's of work, the entire field will benefit! My lab's gonna try V4EXT soon!

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

First study of its kind finds deep-sea mining waste threatens life and foodwebs in the ocean's dim 'twilight zone' A new study led by researchers at the University of Hawaii (UH) at Mānoa published in Nature Communications is the first of its kind to show that waste discharged from deep-sea mining operations in the Pacific's biodiverse Clarion-Clipperton Zone (CCZ) could disrupt marine life in the midwater "twilight zone"—a vital region 200–1,500 meters below sea level that supports vast communities of zooplankton, tiny animals that serve as the ocean's basic food building blocks.

Deep-sea mining waste in the Clarion-Clipperton Zone may disrupt the ocean's twilight zone food webs by reducing the nutritional quality of particles vital to zooplankton and micronekton.

How Jane Goodall Turned Her Childhood Dream into Reality: A Sweet Illustrated Story of Purpose and Deep Determination A heartening testament to the power of undivided intention.

Wildlife advocate, primate expert Jane Goodall dies at 91 Scientist and global activist Jane Goodall, who turned her childhood love of primates into a lifelong quest for protecting the environment, died on Wednesday at the age of 91, the institute she founded said.

Tonight I learned that one of my heroes has died. I loved her and colleagues' "adventures" as a child and grew up to admire her scientific work for so many reasons. RIP Jane Goodall.

The Story Behind “Silent Spring”: How Rachel Carson’s Countercultural Courage Catalyzed the Environmental Movement “It is, in the deepest sense, a privilege as well as a duty to have the opportunity to speak out — to many thousands of people — on something so important.”

Silent Spring was published on this day in 1962, catalyzing the environmental movement. The deeply human story behind it: www.themarginalian.org/2017/01/27/r...

I find this reassuring. LLMs don't replace the need to learn how to write whatsoever.

There really are no shortcuts to thinking super hard for many hours. That is the only wait to do good science. All shortcuts are an illusion.

--> This is good for the humans! Roll your sleeves up and think.

Have you ever looked at some differentially occurring gene clusters in a microbial #pangenome and thought to yourself "I wonder if they contribute to any metabolic modules"?

With the most recent changes, the answer is a few clicks away in #anvio 😇

Hydrogen sulfide production distinguishes Salmonella from close relatives, but its biological significance remains obscure. This study uncovers the secret: Salmonella uses hydrogen sulfide production as a weapon to outcompete E. coli and gain a foothold in the gut.
