“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.

Every new economic news story is just this iconic New Yorker comic by Tom Toro now: www.newyorker.com/cartoon/a16995

A single panel comic from The New Yorker by cartoonist Tom Toro. A man in a town up suit sits around a fire telling a story to three younger characters, also in tattered clothing. The background is a dim post apocalyptic cityscape.

The caption reads “Yes, the planet got destroyed. But for a beautiful moment in time we created a lot of value for shareholders.”

Yup, I wanted to give Microsoft the benefit of the doubt when I built my PC so I installed Windows 11… In retrospect maybe not the best choice but they’re doing their best to make sure Windows 10 is not going to be a viable option for long

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.

That’s genuinely sad. Without competition there’s little incentive to do right by consumers. I really enjoy Linux, but it’s still not workable for certain use cases and technical barrier-to-entry is high. Apple is good but MacOS Tahoe is a garbage fire.

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...

It's an unbalanced centrifuge rotor in a candy bar. Some sick freak is out there putting all the weight on one side of the rotor. Just horrifying these people are allowed to walk among us.

And what about Sam’s song about the guy who kicked the troll because the troll dug up his relative’s shinbone to chew on!? In a wry twist the guy either breaks his foot or has it eaten by the troll (conclusion unclear). Absolute banger! It’s like Peter Jackson didn’t even read the books…

That’s an EPS-12V 8-pin power connector (usually goes to the motherboard). The GPU wants more power than a single PCIe 8 pin will deliver on its own and it may have come with a splitter that takes the EPS connection and converts it to 2 PCIe 8-pin connections. support.exxactcorp.com/hc/en-us/art...

Of course, it all kind of comes out in the wash because you adapt to the mean light level so what ends up mattering is how many "red" photons you absorb relative to other wavelengths, rather than the total number ¯\_(ツ)_/¯

010

Dragos Rezeanu @dragosrevision.bsky.social · 21/06/2025

Aww, thanks Pam! That's super kind of you to say :D I'm so glad to hear it!

000

Dragos Rezeanu @dragosrevision.bsky.social · 21/06/2025

For cones, the probability of absorbing a photon is entirely based on the number of photons arriving and the spectral tuning of the cone type. So if you have the same number of "red" photons arriving and twice as many red cones, you'll absorb twice the photons and produce twice the summed response.

110

Dragos Rezeanu @dragosrevision.bsky.social · 21/06/2025

Definitely not sure how this would relate back to fluorescence, but that's an interesting point! Is the amount of fluorescence you see for a given fluorophore dependent on the spectral tuning of the fluorophore/probability of absorbing that photon, or on the energy of the incoming photon itself?

Dragos Rezeanu @dragosrevision.bsky.social · 21/06/2025

In each L/M cell type, the L and M opsins "compete" for which one gets expressed, and the resulting ratio seems to be based on subregions in each opsin gene that alter binding affinity for proteins involved in transcription regulation. Specific haplotypes make L or M the more likely fate.

000

Dragos Rezeanu @dragosrevision.bsky.social · 21/06/2025

There's actually a lot we know about that! Sticking to Red vs Green (L vs M), L and M cones themselves are the same cell type (not true of S), what makes them L or M is the opsin pigment they express. The L&M opsins are encoded by genes that are lined up in row on the long arm of the X chromosome...

This is a big unknown for now. There’s some evidence that variation in what people perceive as pure green (a perfect cancellation of blue and yellow) may be impacted, but that’s still speculative. Like you said: the brain is just so good at creating a consistent model from really varied input!
