Do you do multiple driver/stressor experiments? @ravignettes and I wrote a paper a few months ago to help you make them even better.
Please share, especially with students!

Since we're in a heat wave:
Despite apparently popular belief, running an electric fan helps even when it is hotter than 35C / 95 F. Humidity matters but 35C is a bad rule of thumb.
Take it from someone who has spent a LOT of time above 35C.

Here's the UK NHS, which says that fans become harmful at 35C / 95 F.
Not as bad as the US but still bad advice, especially given that the UK is more uniformly humid than the US, and the threshold will be higher in humid conditions.

The WHO sets the threshold for fan usage at 40 C / 104 F.
That's 8 degrees C higher than the US limit! It's still probably too low but at least in defensible territory.

New paper out by that describes data analysis tools creating by the Changing Ocean Biological systems Group last year at a workshop in Sweden. check them out for a good resource on coding and analysis:

We still have a few slots free in our experimental design workshop at ITRS on the 30th of June in Brest, France. If you are attending the conference and interested in honing your skills in climate change research/design, please sign up! itrs-home.org/designing-mult…

Delighted to share our new preprint on bioRxiv:

Where we integrated viral metagenomics and mathematical modelling to explore the temperature-driven biogeography of marine giant viruses - where do they live and why? (1/6)

Wait, how did I miss this?

This pernicious idea that publicly funded data belongs to a scientist in perpetuity needs to die. It holds up the entire scientific enterprise to benefit a few senior gatekeepers.
I've encountered this in my field too. Many supposedly public datasets are not.
Did you know that Germany has its own large-scale population-based biobank?

Goodhart's law strikes again.
This is wild. Farmers in Punjab may be shifting burning times to avoid satellite overpass times? It’s the kind of “well what if…” identification complaint R2 might make. timesofindia.indiatimes.com/…

New preprint! A new direction for my research program: Bacteria can use antagonism to forage for nutrients in microbial communities. Shoot spearguns with toxins into other cells and leak out nutrients!

To summarise this excellent thread: Satellites miss ~half of phytoplankton biomass and also do poorly at capturing blooms/peaks in abundance.
Valuable work and I'm going to have to read the paper carefully.
(1/🧵) How much of Earth's phytoplankton do space satellites not "see"? Can chlorophyll from satellites reliably describe phytoplankton biomass? 🛰️🦠
In our new paper in @PNAS, we answer these questions with a fleet of undersea Argo robots 🤖🌊:

We in environmental science need to be more careful when using terms like 'tipping points' & 'regime shifts'. I'm not saying they don't exist, but too often we accept them based on thin evidence.
"Tipping point" ought to mean more than "not a straight line".

I'm talking at a conference later this year (on UX+AI).
I just saw an ad for the conference with my photo and was like, wait, that doesn't look right.
Is my bra showing in my profile pic and I've never noticed...? That's weird.
I open my original photo.
No bra showing.
I put the two photos side by side and I'm like WTF...
Someone edited my photo to unbutton my blouse and reveal a made-up hint of a bra or something else underneath. 🤨
Immediately, I email the conference host.
(FYI he is a great, respectable guy with 5 kids at home.)
He is super apologetic and immediately looks into the issue.
He quickly reports back that the woman running their social media used a cropped square image from their website.
She needed it to be more vertical, so she used an AI expand image tool to make the photo taller.
AI invented the bottom part of the image (in which it believed that women's shirts should be unbuttoned further, with some tension around the buttons, and revealing a little hint of something underneath). 🤯

FYI the conference organizers were super apologetic and took down all of the content with that photo.
