A Novel Pilus System in Candidate Phyla Radiation Bacteria

The Candidate Phyla Radiation (CPR) represents a bacterial superphylum estimated to include between 15–50% of all bacterial species, yet CPR bacteria remain challenging to culture and have been primar...

Researchers and science publishers need to seize the opportunity offered by the drastic shifts in the way news is produced — one reason Nature has joined TikTok.

COMMBAT: a web platform for exploring expression control of biosynthetic gene clusters

Abstract. Bacterial genomes contain thousands of biosynthetic gene clusters (BGCs) responsible for the production of structurally diverse natural products

Yet another functional group that is not as restricted as we thought for 25 years. This is an important reminder that microbes are metabolically more diverse than we give them credit and yet another reminder that 16S rRNA surveys are ignorant about metabolism. Just bc you detect some ANME =/= AOM.

Emergent predictability in microbial ecosystems

A long-standing hypothesis of microbial ecology is that simple patterns might persist despite community complexity or even emerge because of it. However, the concept of “emergent simplicity” remains partly intuitive. Here, we defined emergent ...

12.7 million battery electric vehicles were sold globally in 2025. In 2010, the number was barely 10,000. In China, 1 in 2 new cars sold last year was electric. The transition is happening faster than almost anyone predicted.
