The Murphy Lab did our annual retreat this week. This year's theme was using AI (what it's good and bad for). I wanted to be open-minded to make sure we are not missing something we should be using it for, so we did a few exercises to test, and had presentations.

Greetings! I decided to make a YouTube video of my AlphaFold workshop that I've given a few times in the past year. Caveats aside, people seem to find this useful for thinking about how to model protein interactions and how to interpret various AF outputs 1/2

All right it’s time for the annual β€œplease tell us about one (or a few if you are ambitious) paper from 2025 that really impressed you and why we should all read itβ€œ! Go! If you tell us how it changed your view of the world and what makes it so powerful and consequential It would be excellent.

This paper was written by my WormAtlas colleagues, Dave and Nate, in addition to 5 Nobel Prize winners. Hopefully more attention and funding will find its way to the invaluable C. elegans resources described in the paper.

I'm teaching a literature based class next semester and plan to share a method for reading a paper focused on note taking.

I think many graduate students don't take notes when reading research articles and consequently don't retain information well.

I'd love to hear what people think. 1/🧡

01.12.2025 15:19 β€” πŸ‘ 23    πŸ” 8    πŸ’¬ 5    πŸ“Œ 2

I love the idea of teaching note taking! I also ask my students to answer these questions as they read: What questions were the authors setting out to answer? How did they interpret their results? Do you agree with their interpretation? Did the authors succeed at answering their original questions?

I've always loved the openness and collegiality of our C. elegans community πŸͺ±, but this perspective really helps emphasize just *how important* those traits are for scientific progress. A true tribute to how curiosity-driven science leads to innovation! πŸ™Œ

The C. elegans community is amazing. I email a Nobel laureate for a favor. He immediately responds yes and offers additional help!

Are you an early-stage graduate student (2nd or 3rd year) or early-stage postdoc based in the US or Canada, working primarily in Drosophila? Would you like to help improve the experience of all trainees working in Drosophila research? If so, read on.
