Our work is finally out! Learning from mechanism of #aging to presenting potential therapeutic strategy to slow down #age-related #vision loss! Very proud of my team including several undergrads and thankful for fantastic collaborations across the world! www.science.org/doi/10.1126/...

Congratulations to the winners of our image competition with the @mblscience.bsky.social Embryology course. The winner of the Editor’s choice is an image of a anole lizard eye, acquired by Arthur Boutillon @campaslab.bsky.social. thenode.biologists.com/results-from... #devbio 🔬🎉

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue. The effect presumably comes from the absence of S-cones in the fovea. From Hinnerk Schulz-Hildebrandt: arxiv.org/pdf/2509.115...

Webvision Has A New Home! www.webvision.pitt.edu/2025/09/22/w...

We are pleased to announce that Webvision has been fully migrated to our new home at the University of Pittsburgh. www.webvision.pitt.edu All traffic should not automatically be redirected from the old URLs, but please update your links. Heads up: @pittophthalmology.bsky.social

Webvision is currently in migration. If you are going to the old site, you will see a 404. Check out our new home at webvision.pitt.edu

Super proud of Drs. Handel, Lim, and Ripolles-Garcia and Ms. Khan for representing COVSL at the Bay Area Vision Research Day! #visionscience

New paper! Kudos to first author Jaeeun Lee, who is a fantastic and hard working student. We showed that at photoreceptor presynapses, ELFN1 enrichment depends on postsynaptic mGluR6. www.jneurosci.org/content/earl...

Very proud of former Kumar lab PhD student, Alison Ordway, for receiving a K99 award from the National Eye Institute on her work describing photoreceptor patterning in Drosophila and mosquito compound eyes. Keep your eyes out for Alison when she goes out on the job market.

Our latest manuscript is out, and this one tackles the problem of cellular aging in the retina, using comparative multiomic analysis of zebrafish, mouse, and humans. What led us to work on aging after studying development and regeneration? Explainer follows./1 www.biorxiv.org/content/10.1...

And how!

Research to Prevent Blindness (RPB) is not on Bsky yet, but they have a new website. If you are interested in vision research, RPB is a source of funding for your work. I owe my career to RPB in many ways. www.rpbusa.org

These are the kinds of stories that seem wild, but are firmly based in science and medicine. They also show that science has a long way to go and we should be robustly funding science. Artificial cornea research is underfunded, like most of biomedical science in America. It's time to lead.

The connection between sugar and age-related macular degeneration is stronger than you might think. Research indicates that high-glycemic foods like soda, candy, white bread, and pasta create inflammatory compounds that can harm your retina. Read more: https://bit.ly/465PeiL.

Exciting news! Dr. Marie Burns has been appointed the new Director of the Center for Neuroscience, and it's hard to imagine a better choice for this position! @ucdaviscns.bsky.social @ucdavis.bsky.social @ucd-cbha.bsky.social

Incredible vision in these creatures. And they see color differently than you or I. They see in UV and in green. And some also see in red by shifting the focal point of the wavelength. They also see motion with different eyes. Cool stuff.

Rainbow retinas! While at @mblscience.bsky.social I had the opportunity to check out frog and octopus retinas using super neat birefringence microscopy invented by Michael Shribak, with student Jenna Tijerina. The vertebrate inner retina is so optically clear compared to the outer segments! 🧪🐸🐙👀

Our work on the TET enzymes in retinal development is out. We identified that rod fate is inhibited when DNA demethylation is prevented by removal of the TET enzymes. Interestingly, photoreceptor numbers are normal. We utilized WGBS and bACE-seq to profile the precise localization of 5mC and 5hmC,…

Science is a long game. Translational science, or clinical medicine is only possibly because of basic science discoveries where the clinical applications are not yet known. Also: Nobels are typically awarded for basic science… *exploratory* basic science. True story.

Dr. Sandeep Moothedath Subrahmanian of Penn State College of Medicine is studying how a “molecular switch” causes a stress response protein, REDD1, to build up and damage retinal cells in early macular degeneration. His goal: to stop the disease before vision is lost. Read more: bit.ly/47jUpxN

I am absolutely delighted that my new institution @pittophathalmology.bsky.social has a presence here on Bsky! So much news coming from them/us over the next little while.

Look at this fantastic project using art to teach kids (and adults!) about the visual system! The Vision Sciences Research Network @reseauvision.bsky.social is happy to support this outreach project led by Maria and Marion!

I start as an Assistant Professor at University of Pittsburgh next month.

From 10 years ago as a grad student with @robertmarc.bsky.social to my last day at the U of Utah today. It’s surreal to look out over the valley one last time. On to the next adventure!
