Protist–bacteria partnerships are more common in wastewater treatment plants than we thought. In this ISME communications paper, we uncovered widespread denitrifying endosymbionts inside ciliates, their global distribution, and their temporal dynamics across WWTPs.🦠

RNASky
How does messenger RNA (mRNA) get out of the nucleus to become a protein? Eukaryotic mRNA is packaged, exported, and then translated in the cytoplasm. But how do these steps work? And what are open questions? Check out our new review for our take: www.annualreviews.org/content/jour... (1/3)

What a great story from Heidi. "“We need a molecular definition of what is normal.” In the light of this work, one has to wonder if the molecular is the right place to look for that at all.
One for the heredity scolds: construct a multi-tissue GRM where people
are differentially related to themselves.

as a child, I always dreamed of eating single spaghetti (spaghetto!) exactly like this: slurping them up (but wasn't allowed to, *sigh).

I like the term "intercellular biodiversity" (much more than the old trope of "parasitism") #MicroSky
According to the microbial ecologist Puri López-García, pictured here at a salt flat in the Chilean Andes, some 25% to 50% of all bacterial cells may be parasites of other cells.
A Cell So Minimal That It Challenges Definitions of Life | Quanta Magazine
The newly described microbe represents a world of parasitic, intercellular biodiversity only beginning to be revealed by genome sequencing.

All nations committed under the Paris Agreement to limit global warming to 1.5 degC for good reason. Instead many governments are beholden to the fossil fuel lobby and even subsidize fossil fuel use with your money. We’re now at 1.4 degC & emissions are rising not falling.

Corals are masters of obtaining nutrition via symbioses, in the light and in the dark: deep sea corals can associate with sulfur-oxidizing chemoautotrophs, expressing pathways that oxidize sulfur and fix C.

'Well over a 100k people fled the country seeking asylum. Among them was a young geneticist named George Rédei, who headed for the Austrian border with a small vial of seeds tucked in his pocket.
The seeds belonged to a spindly weed in the mustard family called Arabidopsis thaliana.'

How a humble weed became a superstar of biology
Arabidopsis thaliana was always an unlikely candidate for the limelight. But 25 years ago, the diminutive thale cress launched the botanical world into the molecular era.
