Happy to share this perspective about better integrating the microbiome and symbiosis fields, starting with a call to be more accurate with our terminology journals.asm.org/doi/10.1128/... Was the best experience to write this article with the amazing @khadlily.bsky.social #microbiome #microsky

mGem: Tapping into the language of symbiosis to advance human microbiome research | mBio

An overarching goal in microbiome research is to understand how the complex communities in our bodies contribute to health and disease, and ultimately, we aim to leverage and control these communities to promote health. To continue advancing this work, we need conceptual frameworks that aid in understanding the relationships between us and our microbiota. Conceptual frameworks can ensure that we avoid doing our science in silos by unifying work across disciplines, and they can help form hypotheses and questions for future research. In human microbiome research, there have been various conceptual frameworks that have advanced our science (1–4). In this perspective, we highlight the symbiosis framework and definitions in connection to microbiome research, with the hope that adoption of this framework will advance our ability to study the human microbiome.

Really useful paper explaining why richness/diversity metrics are rarely informative when applied to microbial community sequencing data: enviromicro-journals.onlinelibrary.wiley.com/doi/10.1111/...

Rethinking Alpha Diversity in Marker‐Gene Microbiome Studies: Dominance Matters More Than Richness

Marker-gene microbiome surveys systematically under-sample rare taxa, causing alpha diversity metrics to reflect dominance rather than true richness. This conceptual mismatch can lead to misleading e...

Bacterial immune proteins have repeatedly evolved to become parts of eukaryotic immunity. But how? Our new preprint uncovers a recent horizontal transfer event & shows how eukaryotes co-opted a toxic bacterial immune protein 🦠🧪🧵 1/

Can plant pathogens boost vector fitness? Together with @hassansalem.bsky.social, we review how phytopathogens can spread further by moonlighting as insect symbionts 🪲 More on this nifty lifestyle in @annualreviews.bsky.social! www.annualreviews.org/content/jour...

Plant Pathogens Moonlighting as Beneficial Insect Symbionts

Herbivorous insects can shape the epidemiology of disease in plants by vectoring numerous phytopathogens. While the consequences of infection are often well-characterized in the host plant, the extent...

Our new paper, out today! We resurrected ancient nitrogenases first used by life on Earth 3 billion years ago. We combined synthetic biology and geology & validated their chemical #biosignature in rocks that helps reveal ancient life on Earth!(and beyond!) Link: www.nature.com/articles/s41...

Resurrected nitrogenases recapitulate canonical N-isotope biosignatures over two billion years - Nature Communications

The study shows that nitrogenase enzymes have maintained stable isotope signatures over billions of years, revealing how ancient microbes shaped Earth’s nitrogen cycle and offering a new experimental ...

I can't overrecommend this incredible paper about water skaters (genus Halobates). No one knows how they evolved. No one knows what they eat. They are superhydrophobic, which means water LITERALLY CANNOT WET THEM. Perhaps we should call them anti-water skaters? 🌊🧪 journals.plos.org/plosbiology/...

Why did only one genus of insects, Halobates, take to the high seas?

Oceans cover over 70% of the earth’s surface and house a dizzying array of organisms, including five species of the peppercorn-sized ocean-skater Halobates, which live exclusively at the ocean surface...

Viral "dark matter" dominates the virosphere. In this review by me & @karthik-a.bsky.social, we synthesize what's known, highlight major gaps, and outline paths forward for illuminating viral protein functions in diverse ecosystems.

Viral Dark Matter: Illuminating Protein Function, Ecology, and Biotechnological Promises

Viruses are the most abundant biological entities on Earth and play central roles in shaping microbiomes and influencing ecosystem functions. Yet, most viral genes remain uncharacterized, comprising w...
