Encoding recent movement history with Wormtrails makes spatial differences in C. elegans behavior much easier to see. In this assay, worms not only avoid the hydrogen peroxide gradient on the left, but also move faster near it. 4/

Friends! I am so happy to share our new preprint!

Hydrogen peroxide has been the most common reactive chemical threat to life forms since the Great Oxygenation Event 2.5 billion years ago.

How do animals like C. elegans sense it fast and escape?

showing how microscope resolution has improved more than 10,000× over the past 200 years. The horizontal axis shows year (1800s to 2025). The left vertical axis shows feature size, from 1 micrometer (small bacteria) down to 0.01 nanometers (atomic nuclear structure). The right vertical axis shows resolving power in inverse angstroms. A blue curve at the bottom represents light microscopy, limited by visible-light diffraction to about 200 nanometers. A tan curve rising sharply in the mid-20th century represents electron microscopy, reaching nanometer-scale resolution. A red region near 0.1 nanometers shows aberration-corrected electron microscopy surpassing the electron diffraction limit. A blue region at the top shows ptychography achieving the highest resolving power through overlapping diffraction patterns and computation. Dots label key scientists and institutions at milestones. Overall trend shows steady, then dramatic gains in resolution over time.

The resolution of microscopes has increased over 10,000 fold over the last 200 years.

It's allowed scientists to examine not only cells, but bacteria, then viruses, their protein structure, and, eventually, the individual atoms that comprise them.

Not totally sure why my son wanted a thermal camera for Christmas, but we’re now prepared to drop our first techno demo track.

A novel, fig-associated microbe promotes reproductive success via variable life history mechanisms in C. elegans and C. inopinata Variation in life history strategies is among the most striking features of animal diversity. Simultaneously, the microbes an animal interacts with are a critical and dynamic aspect of the host enviro...

Very excited to share this work led by Austin Link, a graduate student in our lab. We have discovered a novel, fig-associated microbe that promotes reproductive success via variable life history mechanisms in two nematode species.

Very interested. We run a primary literature discussion section for the 300 level evolution class I’m teaching this winter.

Research Associate in Biology The Department of Biology at the University of Virginia invites applicants for a post-doctoral Research Associate position in the lab of Professor Amanda Gibson as part of an NSF-funded project. The Gibson lab is broadly interested in the evolution of avoidance versus resistance as modes of parasite defense. This project specifically tests the idea that host dispersal evolves as an escape in space from parasites, and it evaluates the downstream consequences of dispersal for the evolution of host resistance. The work makes use of the experimental tools and resources available for the model nematode C. elegans and its natural parasites. Associated projects entail evolve-and-resequencing, quantitative trait mapping, and field sampling with spatial analyses. The selected candidate will also mentor undergraduate students in independent research projects through a summer program for incoming transfer students. Find out more about the lab at https://coevolving.org. REQUIRED QUALIFICATIONS: o A PhD in Biology or a related field by the start date. PREFERRED QUALIFICATIONS: Demonstrated conceptual and technical strengths in host-parasite interactions, evolutionary ecology, evolutionary genetics, and/or dispersal biology Experience in basic lab and molecular work A strong background in experimental design, data analysis, and data management Excellent written and oral communication, demonstrated by a strong publication record, consistent with the candidate’s career stage, and presentations at conferences Demonstrated ambition, creativity, independence, and ability to work well with others Experience in and dedication to mentoring junior trainees APPLICATION PROCEDURE: Apply online https://jobs.virginia.edu/us and search for R0078709. Attach a cover letter outlining your qualifications and motivation for pursuing the position, curriculum vitae, and contact information for three individuals who can provide professional reference letters. In the cover letter, please address your fit with the qualifications above and your experience in mentoring undergraduates. Please note that multiple documents can be uploaded in the box. APPLICATION DEADLINE: Review of applications will begin on January 15, 2026. The University will perform background checks on all new hires prior to employment. Anticipated start date for this position is May, 2026, but the start date is flexible. This is a one-year appointment; however, appointment may be renewed for additional two, one-year increments, contingent upon available funding and satisfactory performance. For questions about the position, please contact Amanda Gibson, Associate Professor, at akg5nq@virginia.edu. For questions about the application process, please contact Richard Haverstrom, Academic Recruiter, at rkh6j@virginia.edu.

Inconceivable!

This is normally called embellishment, but embellishment has nothing to do with it. The sparkling light has existed in all its brightness from the very beginning in the world of phenomena. 3/3

I’ve definitely seen lines at our famous campus Prince Puckler’s Ice Cream, but never a happy mob. That’s apparently what a perfect fall Saturday in Eugene following a Friday night football win brings.

Going to break my social media hiatus for a belated congratulations to @kdc509.bsky.social on an outstanding thesis defense last week! I cannot say enough good things about Killian - an amazing scientist and human being.

DAF-2/IGF-1 degradation: Males WAY outlive hermaphrodites! This is so cool. @patrickphillips.bsky.social

Lol @mads100tist.bsky.social. We've tried a number things for mass culture over the years, like self-enclosed "worm balls". But the reality is that running for the hills is a young-male's game.

Great work led by @rosealsaadi.bsky.social and @hlewack.bsky.social

Make males live more than 400% longer and prevent sexual disfunction late in life?! We're down with it.

Bowl of gnocchi in cream sauce next to a tea kettle.

Inspired by my recent workshop visit in Sicily, the lab had an Italian food potluck during lab meeting. I made pumpkin stuffed gnocchi in a nutmeg sage cream sauce, but we have no kitchen. So I finished the gnocchi in an electric tea kettle. Worked ok.

Grew up a huge Dodgers fan but the last serious game I watched was in grad school when Kurt Gibson made the greatest hit I’ve ever seen. So yes, I’ve turned on this baby after seeing the hoopla.

Happened to wear black today, so I got sucked into a lab Louvre heist Halloween dress up.

This is nuts, because we know that we can use synthetic biology to optimize these “beasts” of burden. Not sure of the application. I have visions bacterially manned gates sorting the worthiness of other bacteria.

I'm recruiting a postdoc for my group (based in beautiful Eugene, OR). Please get in touch if you're interested, esp if you'd like to chat at #ASHG25!
