探访ITER:全球最大核聚变能源项目内部
ITER(国际热核聚变实验堆)是全球规模最大、最具雄心的核聚变能源项目,位于法国南部。该项目的目标是复制太阳的能量产生过程,在地球上实现可控核聚变,为人类提供近乎无限的清洁能源。本文深入探访了这个耗资超200亿美元的巨大工程,介绍了其核心装置——重达2.3万吨的托卡马克反应堆,以及各国科学家在解决高温等离子体约束、材料耐受性等关键技术挑战方面取得的进展。

A state-designed worm from 2005 called Fast16 sat undetected on VirusTotal for nearly a decade. It intercepted executable files at the kernel level and silently altered floating-point calculations in high-precision engineering software like LS-DYNA, which was used in Iran's nuclear weapons research. Unlike Stuxnet, Fast16 received little public attention for over twenty years.
Paul Graham reports that Y Combinator startups now have over 75% of their code written by AI, a threshold crossed at least one to two years ago. This parallels a similar transformation at Google, where AI-written code went from 0% to 75% in about two years.
Scientists are increasingly concerned about the potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system. Such a collapse could have severe consequences for North America and Europe.
A compromised version of the LiteLLM Python package (version 1.82.8) was briefly available on PyPI, capable of exfiltrating sensitive credentials like SSH keys and cloud secrets. The malicious package affected any project that depended on LiteLLM, though it was only available for about an hour before discovery.
A supply chain attack has compromised the popular npm axios HTTP client library with 300 million weekly downloads. Malicious versions install a remote access trojan, though some users may have avoided infection through version pinning or older installations. Security experts warn this is a live compromise affecting one of npm's most depended-on packages.
