Frontiers | Cortex Thickness Is Key for the Colors of Iridescent Starling Feather Barbules With a Single, Organized Melanosome Layer The iridescent plumage of many birds is structurally coloured due to an orderly arrangement of melanosomes in their feather barbules. Here, we investigated t...

Unlike the more drab European starling, African starlings evolved unique hollow, flattened melanosomes that can be stacked to different depths to produce a rainbow of chromatic coloration.

This "cortex thickness" tunes each feather to a specific wavelength of light.

Of course, another option is for people to dramatically curb their use of social media, or at a minimum, regularly delete posts after a set time threshold.
If LLMs' success in deanonymizing people improves, the researchers warn, governments could use the techniques to unmask online critics, corporations could assemble customer profiles for "hyper-targeted advertising," and attackers could build profiles of targets at scale to launch highly personalized social engineering scams.

To my mind this is key, if you are engaging in high risk behavior that requires you to post pseudonymously or anonymously online do not have an online presence, especially social media, that is linked to your real identity. This prevents any breadcrumb trails of slip ups and has always been true.

Hey All, I made a header only C++ library (MIT) where line of code inits, then you can start writing to pixels on the screen.

I call it thirteen.h, inspired by the simplicity of the 13h days.

Examples include a mandelbrot viewer and a playable mine sweeper game.

Opinion | I'm a Minneapolis sociologist who studies violence. Here's how ICE observers are helping. Research into how violence occurs shows that disapproval from the people around you can help reduce it.

For @msnownews.bsky.social, I wrote an article about how ICE Watch is grounded in sociological theories of violence prevention.

The reality is that most men will only commit public violence in extremely specific scenarios and ICE Watch disrupts the conditions necessary for escalation.

More work on procedural lens flares in #Godot.

If you want to have a look at the (still very messy!) code: github.com/kb173/godot-...

Outline of how it works:
1. Clip bright spots from the rendered image
2. Warp these spots to create ghosts and a halo
3. Blur
4. Overlay based on a dirt texture

All it takes is one bad faith border security staff calling into question why I am travelling to the US from Canada and back on a UK passport, and I could be in a cold cell for a few weeks waiting for a chance to explain myself.

Trump’s FBI Moves to Criminally Charge Major Climate Groups The Trump administration is targeting climate organizations that received a Biden-era grant.

Wait, what the fuck?

These orgs applied for and received grants from the government, and now, because this administration chooses to pretend climate change doesn’t exist, they’re going to be accused of FRAUD? For work already done and paid for as the government directed?

Like just really. If it were already the case science agreed with the transphobes then the transphobes would not need to fundamentally change the way science is funded in the US and use monetary threats to force the (published) science to start agreeing with them. This is all very unsubtle.

2. Musk's people trying to do same with THE US TREASURY MASTER PAYMENT SYSTEM 🚨

Dreams on a Pillow, the Palestinian video game about the 1948 Nakba, surpassed its funding goal It’s follow-up to the award-winning Liyla and the Shadows of War

Again, my utmost respect for @polygon.com for reporting on Dreams on a Pillow when so many sites and influencers that claim to stand for inclusivity and diversity and equality have ducked speaking about the genocide, about Palestine, and about Palestinian stories.
