With their quick-change camouflage and high level of intelligence, it’s not surprising that the public and scientific experts alike are fascinated by octopuses. Their abilities to recognize faces, solve puzzles, and learn behaviors from other octopuses make these animals a captivating study.
To perform these processes and others, like crawling or exploring, octopuses rely on their complex nervous system, one that has become a focus for neuroscientists. With about 500 million neurons—around the same number as dogs—octopuses’ nervous systems are the most complex of any invertebrate. But, unlike vertebrate organisms, the octopus’s nervous system is also decentralized, with around 350 million neurons, or 66 percent of it, located in its eight arms.
“This means each arm is capable of independently processing sensory input, initiating movement, and even executing complex behaviors—without direct instructions from the brain,” explains Galit Pelled, a professor of Mechanical Engineering, Radiology, and Neuroscience at Michigan State University who studies octopus neuroscience. “In essence, the arms have their own ‘mini-brains.’”

It's early June and the vibes are decidedly off in Cupertino.
The hype leading up to Apple's last two developer conferences felt much different. There was anticipation in 2023 for a potentially groundbreaking new headset. In 2024, there was a sense of urgency leading up to the company's AI announcements and whispers that Siri might actually, finally be good at something. But 2025?
Well, things are different.
The Vision Pro was the big announcement at that 2023 show, and it's, uh, still around. Apple has reportedly cut production due to slow sales, and you can get one at a steep discount on eBay. Maybe the price is wrong. And the big AI announcement last year? How's that going? As it stands, Apple Intelligence is stalled out. The features that Apple managed to deploy are underwhelming, and the meaty update to Siri has been delayed - maybe even for years. It sounds like the whole thing was a real fiasco inside Apple, and publicly, the company took down an ad showcasing Siri features that simply don't exist yet. Ouch.
And then there's the legal stuff. In 2021, a court in California ordered Apple to let developers add links allowing customers to make purchases outside of their a …

The daughter of a woman who was killed by extreme heat during the 2021 Pacific Northwest heat dome has filed a first-of-its-kind lawsuit against major oil companies claiming they should be held responsible for her death.
The civil lawsuit, filed on May 29 in King County Superior Court in Seattle, is the first wrongful death case brought against Big Oil in the US in the context of climate change. It attempts to hold some of the world’s biggest fossil fuel companies liable for the death of Juliana Leon, who perished from overheating during the heat dome event, which scientists have determined would have been virtually impossible absent human-caused climate change.

I usually struggle with strategy games. They're typically too hard for me, and I often get overwhelmed at managing multiple characters or squads. But I couldn't put down Teenage Mutant Ninja Turtles: Tactical Takedown, which blends ideas from strategy games and classic TMNT arcade games to keep things snappy, easy to play, and full of action.
One way Tactical Takedown - developed by I Am Your Beast maker Strange Scaffold - keeps things simple is by having you play as just one character in each of the game's 20 levels. The four turtles have different movesets; Leonardo, for example, uses his swords to aggressively attack enemies, while Michelangelo can zip around the playing field on his skateboard. You're able to customize each turtle's arsenal by buying new moves, but I didn't change the movesets at all and got through the game just fine.
Battles take place in a grid overlaid on small chunks of very TMNT locations, like a street, sewer, or subway system. Every turn, you have six "action points" to spend as you please, whether that's moving around the level or attacking bad guys. You just press a button to use one of your moves, no menu required, which speeds things up considera …
