When The Rock pinned Cody Rhodes at WrestleMania 40 (Night 1), I might get cooked for saying this, but I don’t think The Rock should’ve pinned him because we never got a match between them. He pinned him for no reason 😭

On Jan. 10, two test stands at NASA Marshall – the Propulsion and Structural Test Facility and the Dynamic Test Facility – were removed by carefully coordinated implosions. The demolition of these historic structures is part of a larger project that began in spring 2022, targeting several inactive structures and building a dynamic, interconnected campus ready for the next era of space exploration. Learn more about these structures and their legacies here:

The Pyramid of the Sun at Teotihuacan 🇲🇽 is one of those structures that breaks your sense of proportion. It’s really hard to capture its scale. 🧵 Let’s try anyway…

In two new papers we have found that the ESM2 language model generalizes beyond natural proteins, and enables programmable generation of complex and modular protein structures.

Researchers at the Chinese University of Hong Kong, Shenzhen have developed a snail-like robotic swarm that can connect to form larger structures. These robots use a two-mode adhesive system inspired by land snails, allowing both movement and strong connections. They introduced this system in 2024, and tests show it can travel on rough terrain, climb obstacles, and combine to handle more complex tasks.

The dinner scene does not end at the table. Wesley ends up back at the football club — and for once, he might be the one who needs someone to stay with him. A playable scene from Our Campus Life. Demo 2.0 is now on Steam, links are in our pinned post. #OurCampusLife #BLgame #VisualNovel

University of Pennsylvania researchers created ModQuad—quadrotors that dock mid-air and self-assemble into larger flying structures, then fly together as one, sharing control and stability.

We were back at this property in Pretoria West to demolish unsafe and illegal structures built by a serial non-compliant businessman. The City got a court order that enabled us to finally demolish structures that pose a danger to citizens. City of Tshwane

What happens when two incredibly dense neutron stars crash into each other? Researchers used a NASA supercomputer to take a closer look at the maelstrom of interacting magnetic structures around neutron stars in the moments before they crash.
