- Reposted by Tristan CaroIn addition to the 2 postdoc jobs posted yesterday, we’re recruiting 2 PhD students (environmental microbiology/ molecular ecology) to join us from April. The projects will map microbial populations across niches in bioelectrochemical systems relevant to biomethanation & link them to performance.

- Reposted by Tristan CaroHappy to talk to @olliemilman.bsky.social about the potential impacts IF people followed the new dietary guidelines. We’re talking potentially 100M acres of additional ag land and 100s of millions of tons of more CO2e. But if we instead ate more plants, we could have our protein and forests, too.

As a result of this and seeking a better life balance, I have accepted a new Full Prof position at the University Helsinki, Finland 🇫🇮🤩 I will miss CA deeply, but a new adventure awaits 🐟 www.nature.com/articles/d41...

- The problem here isn't policy requiring open access. The problem isn't even necessarily journals charging APCs (though, that's certainly a big component). The problem is that we live in an academic environment that values journal title over substance. It's a culture problem. (1/n)

- Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other. Shared by @gizmodo.com: buff.ly/yAAHtHq
- I agree with this, but I think 'learning requires effort' is sadly not something many internalize. I encounter loads of students who view difficulty learning as evidence of their inherent insufficiency; therefore they self-select out of certain subjects the moment things get tricky (1/2)
