Cardiovascular complications from covid-19 have been seen widely since the early days of the pandemic. Katharine Lang reports on why covid-19 is “a vascular disease masquerading as a respiratory one” bmj.com/content/392/bmj.s31?…

Fei-Fei Li says language models are extremely limited. This @GoogleDeepMind paper makes almost the same point, just in the world of video. The models are just very advanced pattern matchers. They can recreate what looks like reality because they’ve seen so much data, but they don’t know why the world works the way it does. The models can generate clips that look stunningly real, but when you test whether they actually follow basic physics, they fall apart. The Physics-IQ benchmark shows that visual polish and true understanding are two completely different things. Here, the authors build Physics-IQ, a real-video benchmark spanning solid mechanics, fluids, optics, thermodynamics, and magnetism Each test shows the start of an event, then asks a model to continue the next seconds. They compare the prediction to the real future using motion checks for where, when, and how much things move. Scores then roll into a single Physics-IQ number that caps at what 2 real takes agree on. Across popular models, even the strongest sits far below that cap, while multiframe versions usually beat image-to-video versions. Sora is hardest to tell apart from real videos, yet its physics score stays low, showing realism and physics are uncorrelated. Some cases work, like paint smearing or pouring liquid, but contact and cutting often fail. arxiv. org/abs/2501.09038
Fei-Fei Li (@drfeifei) on limitations of LLMs. "There's no language out there in nature. You don't go out in nature and there's words written in the sky for you.. There is a 3D world that follows laws of physics." Language is purely generated signal.

The 2025 BEHAVIOR Challenge, launched by @drfeifei's team at Stanford, is a global competition to train robots in household tasks, testing reasoning, navigation, and manipulation in simulated homes. ⦿ 50 tasks, 1,000 activities (e.g., cooking, cleaning) ⦿ 10,000 expert demos (1,200 hours) ⦿ Baselines methods like ACT, OpenVLA, and π0 The submission deadline is November 15th. behavior.stanford.edu/challe…

"In 2010, the IEA estimated that there would be 410GW of solar panels installed around the world by 2035. There is already more than 4 times that capacity, with about half of it in China" - 10 years earlier ft.com/content/c4068478-c091…

A research team from València has developed an innovative biosensor capable of detecting airborne viruses in real time and at low cost, without the need for chemical markers or laboratory procedures. This sort of technology could be a total game-changer! upv.es/noticias-upv/noticia-…
