How specific are heritable symbioses?

And what can we learn from swapping obligate symbionts across host species?

We address this in our latest, led by @inespons.bsky.social & in our collaboration w/ @microbiome.bsky.social 🦠🪲 Out today in @natcomms.nature.com!

New today: We're petitioning NSF to revert GRFP eligibility criteria to last year's terms, to avoid pulling the rug out from under the earliest of early-career scientists who had every reason to think they'd be able to apply this year. Sign and spread the word!

I just want to highlight that what is being said is in the context of the current climate conditions. As with anything, if climate change continues to be unmitigated, this story will likely change.

Poem titled "Gnawed." The text of the poem reads:

Gnawed

Kalends of April, 2020

I can feel the rat,
dark and angry,
buried
in the furrows of my chest,
trying hard to pull apart
the fiber of my breathing.
Twisting. Writhing.
Clawing
with a feral-hearted hatred
at the bonds that sinew
soul to skin.
I cannot walk across the room without
the rasping of its teeth
along the inside of my ribs,
or speak without it screaming
in the shallows of my breath.
I can only lie beyond
the borders of my life,
checking the thermometer
a hundred times a day
as all the while
I am being
eaten
from the inside out.

	– John Wyatt Greenlee

Early in the pandemic I spent 2 terrible weeks in isolation, unable to breathe or walk across the room. Expecting my temp. to spike, & knowing that then I'd have to go to the hospital. Worrying I was dying.

In the middle of this anti-vax bullshit, I thought it was worth saying what it felt like:

Holy shit:

Stateline spoke to nearly a dozen firefighters, agency staffers and contractors, who said that top officials assigned to the fire deployed the crews to a remote location under false pretenses so federal agents could check their immigration status.

It’s crazy that America just like. Destroyed science. Just looked at its golden goose and went “wow should we kill this? And not for the gold, but just because we fucking hate this thing”

And if you tell random people about it they go “no, that doesn’t seem true” and just refuse to believe you

You’re not the only one who feels like you’re losing your mind. Everyone I talk to has said this to me. This world is taking a toll on all of us, even those who are trying not to pay attention. Let this connect you to other people in solidarity rather than isolate you.

Pete, my long hair domestic cat thats mostly white white some grey splotches looking very concerned inside a pet crate inside a car. There is a blue blanket underneath him. Behind him, with a separator in the crate, is my partner's cat, Wednesday, a black short hair domestic cat. She's just looking to the side, much less concerned than Pete.

Now Wednesday has stolen Pete's blanket and sits on it while Pete is mostly now on the plastic crate bottom. Both have annoyed looks on their faces from the hours of car time.

My latest: Polar scientists warn that the White House and NSF are planning to terminate the Nathaniel Palmer, the only US research icebreaker capable of handling Antarctic extremes, this October.

So far the plan has seen minimal pushback from Congress.
