OpenAI said that a coalition of states had opened an investigation over a wide range of its practices, including its handling of user data, safety of minors and advertising activities
A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space。 Turbulent plasma and powerful stellar storms can spread an ultra-narrow radio transmission across a wider range of frequencies, making it much harder for traditional searches to

Researchers discovered a way to reverse the direction of energy flow in turbulence, challenging a theory that has stood for more than 80 years。 The finding could open new possibilities for controlling ocean currents, improving medical technologies, and enhancing climate forecasting
Scientists have found that staple-shaped particles can tangle together to create a material that is both strong and flexible。 Unlike conventional materials, these particles can be locked into a sturdy structure or rapidly unraveled using vibrations。 The unusual behavior could open the door to recyclable buildings, reconfigurable structures, and eve
New studies suggest consciousness can't be judged solely by behavior, whether it's a chatbot discussing philosophy or a bee searching for nectar。 Researchers are increasingly focusing on the internal mechanisms of brains and computers, concluding that today's AI is likely not conscious while leaving open the possibility for both conscious insects a
Scientists discovered that rice behaves in a highly unusual way: it weakens under rapid compression but stays stronger when pressure is applied slowly。 Using this effect, they engineered a new material that reacts differently to gentle movements and sudden impacts。 The material can adapt its stiffness automatically, opening the door to safer soft r
Researchers at EPFL have developed a chip-scale ultrafast laser that performs on par with traditional tabletop femtosecond lasers。 The innovation could make advanced laser technologies far smaller, cheaper, and more accessible for applications ranging from medical diagnostics to atomic clocks
Quick framing, since the post is long: I did robotic manipulation research at OpenAI from 2017–2020, and the tabletop setup back then cost roughly 10x this one and took a team to run。 This project is me testing whether a single person can now do meaningful work on the same class of problems: starting with physical and software setup。A few decisions
Oxford physicists have created an entirely new type of Schrödinger’s cat-like quantum state using components that are themselves highly quantum in nature。 The advance could open new possibilities for more resilient quantum computers and deeper insights into the strange rules that govern the quantum universe
文｜肖漫编辑｜李勤 6月18日，蔚来同时向两代平台车型（包含8款NT2.0平台车型、4款NT2.5平台车型，以及6款NT3.0车型）推送了最新版的世界模型，这意味着，蔚来现在能让同一套复杂的智驾代码，现在能跑在不同代际的芯片上。 软件迭代节奏被硬件绑架曾是一个困扰行业的难题。很多车企无法在不同版本、配置的车型上迭代同一款软件，这带来的结果是，很长时间内只有使用最新版本硬件的车才能用上最好的软件，老车主被背刺
Scientists have uncovered unexpected quantum complexity inside cobalt, a metal long thought to be fully understood。 Advanced measurements revealed a dense network of topological electronic states that remain robust at room temperature。 These states enable extremely fast electron behavior and can be switched or controlled using magnetism
