Preprint alert: Putative phages with dsRNA genomes. Intriguing what bacteria they may infect. Nature’s diversity continues to astonish! www.biorxiv.org/content/10.1...
“Paraxenoviridae”, a putative family of ubiquitous marine bacteriophages with double-stranded RNA genomes
Fragmented and primer Ligated DsRNA Sequencing (FLDS) was used to reconstruct five complete, bisegmented RNA genomes of paraxenoviruses, a group of viruses that was previously identified in the ocean ...

The Russian spelling and pronunciation of Kyiv throughout the ages was no accident. While the name gets its origin from an empire that predates Russia, a series of policies by the Russian Empire and the Soviet Union that sought to Russify Ukraine and the Ukrainian language distorted its roots.
Kyiv, not Kiev — How Ukrainians reclaimed their capital
For decades, if not more, English speakers the world over referred to Ukraine’s capital as Kiev, pronouncing it kee-yev. Few people knew they were using the Russian name for the city. The city is pro...

I’m very fortunate to be at the 2025 CRISPR Meeting in Christchurch to share our latest work on the quirky Cas12a diversity. What an amazing crowd and location!

The diversity of microbial defenses is amazing! Type IV Thoeris system shows an ancient innate immunity mechanism which uses a TIR protein to make N7-cADPR, activating a caspase-like protease to block phages. Learn more: www.science.org/doi/10.1126/...
TIR signaling activates caspase-like immunity in bacteria
Caspase family proteases and Toll/interleukin-1 receptor (TIR)-domain proteins have central roles in innate immunity and regulated cell death in humans. We describe a bacterial immune system comprisin...

Our paper out @Nature: CARD domains mediate anti-phage defense in bacterial gasdermin systems

CARDs are essential for caspase recruitment during human inflammasome activation. We now find them in bacterial immune systems

Congrats Tana Wein! Thank you Kranzusch lab!

Das Ende einer Ära: Heute fand die allerletzte Klasse in meinem geliebten Yogastudio statt, das mir in den letzten sechs Jahren ein Zufluchtsort war. Danke, Clau, für all die Posen und erholsamen Savasanas.

This is just wild: using AI-driven structural predictions, this study discovered how a phage-encoded “Cas12 hacker” hijacks the bacterial host’s thioredoxin enzyme to supercharge its DNA-cleaving ability. www.biorxiv.org/content/10.1...
AI-driven discovery of host thioredoxin as a CRISPR enhancer of phage-encoded miniature Cas12 hacker nuclease
The evolutionary arms race between bacteriophages and their bacterial hosts has driven the evolution of sophisticated adaptive immune systems, such as CRISPR-Cas, as a crucial defense mechanism. While...
