“We have a population that has learned — correctly — that pharmaceutical companies have lied, that institutions have failed them…But the response has not been better skepticism. It has been the migration of trust from one set of financially motivated actors to another.” Great point here

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.

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...

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…

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

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.
