If only my ancestors had been fortunate enough to marry into the branch of the bacteria family that could photosynthesize, like all my little green cousins here.

Transcript:

[Cueball and Beret Guy, seen from afar in silhouette, are walking up a grassy hill.]

[They continue walking up the hill, reaching its grassy summit. Now with normal lighting. Beret Guy is a bit ahead of Cueball.]
Beret Guy: I learned something today.
Beret Guy: I went on one of those family tree sites and kept clicking back, and it turns out I'm related to stromatolites!

[Closeup on Cueball. Beret Guy's reply comes off-panel from a starburst on the right edge of the panel.]
Cueball: The bacterial mats?
Beret Guy [off-panel]: Yeah! A few billion years back, on my mitochondria's side.

[Cueball and Beret Guy standing on the top of the grassy hill facing each other. Berety Guy holding a hand out towards Cueball.]
Beret Guy: My Archaean ancestors absorbed some bacteria that were cousins of stromatolites. That's how I got mitochondria.
Beret Guy: Cell nuclei, too.

[Cueball is standing behind Beret Guy who is now sitting down in the grass leaning back on one arm with the other arm resting on his bent knee.]
Cueball: I think there are still living stromatolites. You could get in touch.
Beret Guy: Nah, they're probably busy. I don't want to bother them.

[Cueball is sitting behind Beret Guy who is now lying down, both again shown in silhouette from a far, revealing they are on the top of the grassy hill.]
Cueball: So what are you going to do with this knowledge? Nothing?
Beret Guy: Lying on a hill in the warm sun is an old family tradition.

They're continuing to search for a square with the same area as the circle, as efforts to construct one have run into difficulties.

Transcript:

[In a single panel, White Hat, Ponytail, Miss Lenhart, Cueball, and Megan are standing in a field. Ponytail is holding a notebook and taking notes, Miss Lenhart is kneeling and holding her hands on a circular object with the radius marked on it, Cueball is holding a large caliper-like measuring instrument, and Megan is taking a photo with her phone sideways.]

[Caption below the panel:]
Math breakthrough: Dimensional analysts have discovered a real unit circle. Once they measure it, units can finally be added to all our geometry textbooks.

AI summary

The webpage discusses leaked documents revealing the capabilities of Graykey, a phone unlocking and forensics tool utilized by law enforcement globally. According to the documents obtained by 404 Media, Graykey can retrieve only partial data from modern iPhones running iOS 18 and iOS 18.0.1. There is no information on its functionality with the recently released iOS 18.1. This leak is significant for Grayshift, the company behind Graykey, especially since it has been acquired by Magnet Forensics, another player in the digital forensics field. Unlike its competitor Cellebrite, which has experienced similar leaks, this is the first detailed disclosure of the specific phones Graykey can and cannot access. The documents also provide insights into Graykey's capabilities with Android devices. Overall, this situation highlights the ongoing struggle between forensics tools and phone manufacturers like Apple and Google. The information indicates a complex interplay in the evolving landscape of mobile device security and law enforcement access.
