This year's hurricane season has been unusually quiet, and a new study suggests this might become the norm. According to researchers at Princeton, the warmer the climate gets, the fewer tropical cyclones form. But fewer doesn't necessarily mean better. www.youtube.com/watch?v=fwyI...

One of the biggest debates in tech at the moment is the question of whether current AI models can become conscious. Whatever “conscious” means. According to a group of biologists, current AI models are far from it. www.youtube.com/watch?v=Q-tc...

For decades, astrophysicists have told us that the Milky Way sits inside a huge halo of dark matter. But new measurements of how the outer stars of our galaxy move don't seem to fit that picture, nor the main alternative, modified gravity. So what's going on? www.youtube.com/watch?v=FExs...

For years, experts have tried to predict how fast artificial intelligence would progress, and theyve been wrong again and again. Benchmarks they expected in a decade fell in a year. But in some areas, they got it wrong in the opposite direction. Lets take a look. www.youtube.com/watch?v=xdwF...

A detector in Russia caught a single photon with an energy far beyond anything particle colliders can produce. According to physics as we know it, it should never have made it to Earth. Now a team of physicists says it might be the first evidence for quantum gravity. www.youtube.com/watch?v=3rxQ...
