When someone says „Scientists do not want you to know“ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

I'm constantly trying (/failing) to get this point across. If you're a trained expert in a field, then it may be worthwhile to question the scientific consensus of your peers. If you're not, the scientific consensus is absolutely the best you can do and it's arbitrary foolishness to disregard it.

You know what’s wild? I haven’t used the Windows side of my dual boot PC in like… 6 months. Between ads, user-antagonistic design, AI everything, and Windows updates seemingly breaking major systems ~50% (charitably) of the time, it take a “no other options” situation to get me into Windows now… 1/

I’m one, maybe two unprompted “by the way… I have some new capabilities if you enable Gemini” ads away taking a sledgehammer to every Google home product in my house… I don’t want your garbage autocorrect controlling my lights, leave me TF alone.

Princess Bride and puppy snores, not a bad way to close out the year : ) Happy New Year everybody 🎆🍾

Today’s xkcd made me cry. In a good way. xkcd.com/3172/

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...

Please be sure to check your kid's candy VERY carefully. I just found an unbalanced centrifuge in a Snickers bar. 🍬☠️💥

This only happens to you once

Reading the Lord of the Rings for the first time in ~20yrs and I forgot how much of Fellowship is just songs. Feeling so cheated that the movie left out the song about the cat, the dog, and the cow that got super drunk one night, broke a fiddle, and scared the cow so bad it jumped over the moon…

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

FINALLY! Although knowing Microsoft this’ll also automatically invoke CoPilot for some godforsaken reason, just to juice the numbers… www.theverge.com/news/767551/...

Installing Ubuntu on a separate SSD so I can dual boot my PC… so this is what a slippery slope feels like

This… this is my Elysium #ColorimetryNerdHeaven

The local Safeway just started locking up their ice cream and I wanna take whatever moron executive thought this was a good idea and toss them casually into a wood chipper… this might seem extreme but I feel it’s justified. NEVER get between a stressed out grad student and their Ben & Jerry’s

If you put googly eyes on the Pillars of Creation you get muppets 😄😄

Literally the only macro on my phone and computer: ¯\_(ツ)_/¯ It’s mapped to the word “shruggie” 😂

Me: "What did you learn at journal club today?" Intern: "That one day I'm going to publish a paper, and a bunch of people are going to sit around a table and rip it apart."

It’s been a weird, unproductive week at the lab and I’m feeling a little down. So here are 10 cool facts about vision:

PSA: around 5-8% of the population has a color vision impairment for red/green. Many talks at #2025ICDB still use red-green LUTs on slides that are not accessible to everyone. Changing to more accessible colors is doable and easy. We can do better. #devbio #ICDB2025 #WeTheColorBlind

Question for my science peeps. I’ve been resisting using AI coding tools for almost anything beyond documentation looking while building my data analysis pipeline for a few reasons. From most practical to most personal: (1/n) 🧵

Update: this morning’s ear worm is “Belle” from Beauty and the Beast so… a distinct improvement I’d say! Although my papa is definitely going to get kidnapped later so not all good news.

Woke up this morning with Maroon 5 - Payphone* stuck in my head from the moment I hit consciousness… that’s the modern equivalent of a dark omen, right? I’m not misreading this? *I have not heard this song in years

Don’t mind me, just wading into a new subfield of vision research with decades of extremely thorough and contentious research across about 10 animal models plus human psychophysics. If you need me I’ll be in the aisle that sells information-fire-hose-to-brain adapters… Oooo they’re on sale! 🫠

Lately I've been struck by a wave of nostalgia for buying things in person... in a store... where I can actually see and touch and try them. This is especially true for electronics. I don't know what caused it but I'm just so tired of ordering shit online, convenience be damned.

(1/6) Thrilled to share our triple-N dataset (Non-human Primate Neural Responses to Natural Scenes)! It captures thousands of high-level visual neuron responses in macaques to natural scenes using #Neuropixels.

Friday morning timeline cleanse: Seattle sunset at Green Lake from earlier this week.

It’s incredible how adaptive optics has absolutely transformed vision research 🤯 it’s not an exaggeration to say AO techniques are ushering in a new age of psychophysics research in vision science. And that’s just one of several applications!

Some of my favorite signs from yesterday’s #standupforscience rally in Seattle. Incredibly heartening to see the whole scientific community come together like this 🥲

#standupforscience Seattle!

1. Today the NIH director issued a new directive slashing overhead rates to 15%. I want to provide some context on what that means and why it matters. grants.nih.gov/grants/guide...

A long post about what’s happening to the science funding agencies in the US and why. As mentioned, this one just kept getting longer even as I kept stripping curse words from it. www.science.org/content/blog...

NSF has created an Executive Order Implementation webpage to ensure the widest dissemination of information and updates. We will continue to communicate with you as we receive additional guidance. new.nsf.gov/executive-or...

I have a lot going on right now (lots good, some bad) and I find myself feeling super grateful for the refuge of art. My partner got me back into pottery last year, and it’s played a huge role keeping me sane and happy. Being a scientist is amazing, science+art is greater than the sum of its parts.

Hot take: The phrase “PhD-Level Intelligence” is meaningless marketing garbage that relies on the childish idea that “PhD” simply means “super smart.” It’s just catastrophically misguided. Which PhD!? A PhD isn’t an indicator of general “intelligence” it’s an indicator of specialization.

My favourite was having dinner with a bunch of Oxford ornithologists. "Braveheart was RUINED for me about halfway through. Everyone knows black-headed gulls didn't nest inland in Scotland until the 1950s"

Starting the year off with a publication in JOSA A about a portable, surprisingly accurate iPhone-based color vision test we prototyped! Basically a little hand-held Anomaloscope. Lots of potential to make accurate color vision testing way more accessible : )

Best end of year roundup every single year, bar none 🥹

31 December 1995. Still the perfect goodbye.

Excellent suggestion for anyone wanting to explore the color vision and color perception literature. The refs in this paper are packed with some of the most important papers in the field.

Stuff like this is genuinely fun as a silly game, but a reminder from your friendly neighborhood color vision scientist that it absolutely CANNOT be used to compare performance between people using different/uncalibrated displays or even the same display in different viewing environments.

Neuroscience students asked us to teach a PRACTICAL course on experimental methods, and it is now on YouTube! Please like and repost to help us get the word out! www.youtube.com/playlist?lis... Lecture 1: Signals and data acquisition Focusing on hardware, digital/analog I/O, synchronization 🧵

I know this icon is supposed to be a video camera, but it looks more like a blocky angler fish in the middle of a conversation.

Every time I read a vision paper I find a several new rabbit holes to dive into. Today's find: did you know humans can reliably differentiate visual scenes based on the relative amount of dark vs light patches? It's called "skewness" and may be a result of asymmetric adaptation at the cone level.
