An image that reads: Friedrich Schiller University Jena: Preparing your application for a MSCA Postdoctoral Fellowship hosted by the University of Jena. Invitation for a Master class.

A medium sized German city. On the right is a picteruesque river in the glowing daybreak. Around the city are gently rolling, green hills.

Are you interested in a postdoc in Germany on fungal pathogen biology, genomics, or antifungal resistance? My Uni (@uni-jena.de) is hosting a free two-day masterclass in June on preparing MSCA Postdoc Fellowships with it as host.

If you are interested in writing a fellowship with me, get in touch!

We are looking for a #postdoc to join the VEO Group @microverse.bsky.social @uni-jena.de and build an experimental research line into the dynamics and functioning of microbial communities: jobs.uni-jena.de/jobposting/1...

I had some awesome cold brew in Kyoto. I’ve tried to figure out how to make it as good at home, but it is harder than it looks. #coffee #Japan #coldbrew

Where’s Waldo?: Originally depicted shirtless, Waldo was given his iconic red-and-white striped shirt to appease censors who took issue with the fugitive’s tattoos chronicling his murders for the Russian mob.

Brave New World: Bans on Aldous Huxley’s dystopian novel set in an authoritarian near-future proliferated when George Orwell’s 1984, a later dystopian novel set in an authoritarian near-future, was found to be much more straightforward and digestible.

We are deeply saddened by the passing of Dr. Dickson Despommier.

A brilliant scientist, storyteller, and friend, he shared his vast knowledge and infectious enthusiasm with all who listened.

We will miss him dearly. Our heartfelt condolences go out to all who knew and loved him.

Peer review is (at best) a smell test for good/bad papers. Reviewers can be, and often are, fooled.

When I review a paper I ask 1) Does this have intellectual merit? 2) Is there anything obviously in error? I can’t guarantee a “perfect” review. I shouldn’t expect one from anyone else.

I just watched this old film, and it hit me in a different way. Under 15 minutes, and possibly one of the biggest jumps forward in movie history.

I think I like this new-Twitter.

If you take all the land on earth and divide by the total global population, you get about 5 acres per person.

The fact that we can feed everyone is amazing. The idea that we can keep feeding everyone is dubious. Unsustainable is the word people use, I think “terrifying” is more accurate.
