Modulation of methyl–coenzyme M reductase expression alters the isotopic composition of microbial methane
The stable isotopic composition of microbial methane varies substantially, and the underlying causes are debated. In this work, we experimentally controlled the abundance of the central enzyme in meth...

Our story about microbial methane is out! We found that reducing the expression of a key gene of methanogenesis modulates the isotopic composition of the methane:

Phosphite oxidizers 🤝 Methanogens
In our new paper on “Lithosyntrophy” we show that phosphite oxidation drives methanogenesis through interspecies H2 transfer. Lithosyntrophy establishes a novel mechanistic link between the #phosphorus and carbon redox cycles

But the ocean also consumes all that oxygen it produces so it's net zero. 🌊
What is common knowledge in your field, but shocks outsiders?
The ocean produces a huge chunk of the world's oxygen a lot from a class of cyanobacteria called prochlorococcus

Food systems are the #2 contributor to climate change, the #1 driver of deforestation, the #1 driver of biodiversity loss on land, and the #1 user of freshwater.
(It follows that food systems contain many solutions to these problems.)

Enter a Paleolithic ritual chamber deep within Manot Cave, Israel, where you’ll find a boulder engraved with designs from around 36,000 years ago. The site is the earliest known evidence of religious behavior in the Paleolithic Levant.
