In Hitchhiker's Guide to the Galaxy, faster-than-light travel is enabled by math based on restaurant bills.
I propose that numbers in collaborative grant budgets follow the same rules of non-determinism. I just can't.

At the Forest’s Edge: New Research Uncovers How Microbes Shape Ecosystem Resilience
Microbes are everywhere – on your skin, in your gut, in the soil beneath your feet, even floating in the air you breathe. Most people think of microbes in simple terms: some make you sick, while other...

What fungi live in the leaves of Pando, the massive aspen clone in Utah, USA? And how do they vary across the spatial extent of this 43 hectare clonal plant? Find out in this article in our latest issue of Fungal Ecology: doi.org/10.1016/j.fu...

New paper is out with the amazing @greenwoodthegreat.bsky.social
We used the largest tree on Earth (Pando) to test edge effects on microbial assembly without the background noise of host genetic variation!

Grading and googling hallucinated citations, as one does nowadays, and now that LLMs have been around for a while, I've discovered new horrors: hallucinated journals are now appearing in Google Scholar with dozens of citations bc so many people are citing these fake things

Bioinformatics Code Rot: Do We Have an Abandonware Problem?
Graduate students need novel tools to publish. Labs lack funding for maintenance. How can we build sustainable bioinformatics software without fixing the incentive structure?
