本文汇总了2025年2月17日发布的科技、招聘、投资等领域的最新动态。重点关注了OpenAI在AI模型上的突破,以及Reid Hoffman在AI药物研发领域的新尝试。同时,文章也提到了超音速飞机Boom XB-1的首次超音速飞行,并探讨了未来城市发展的新模式,如自由城市的概念。此外,还包括多个领域的人才招聘信息和科研项目,涵盖AI安全、长寿科学等多个前沿领域。内容丰富,信息量大,适合对科技趋势感兴趣的读者。

🚀OpenAI发布“深度研究”模型,性能显著提升,在自动化研究任务上展现巨大潜力,被认为是自GPT 3.5以来最具生产力的技术产品,并计划在“数周到数月”内推出GPT-4.5和GPT-5。

✈️Boom Supersonic的XB-1实验飞机成功完成首次超音速飞行测试,突破音障三次,成为首架突破音障的私人开发飞机和首架在美国大陆上实现超音速飞行的民用飞机,并提出通过技术手段实现“无音爆”超音速飞行的可能性。

🏙️多项政策与研究关注未来城市发展,包括“自由城市”白皮书,旨在通过开放联邦土地和减少监管来促进就业和投资;以及对自动驾驶技术如何影响城市规划的讨论,关注其在构建更公平、高效和宜居城市中的潜力。

🧬长寿科学领域受到关注,Foresight Institute提供Longevity Bio & Molecular Nano Fast Grants,鼓励探索生物ostasis、替代、低温学、纳米设计和AI自动化等新思路。同时,针对“短睡眠者”基因的研究也获得资助,探索通过基因手段减少睡眠需求。

Boom goes supersonic

A few weeks ago I went to Mojave to witness the first supersonic flight test of the Boom XB-1 experimental plane. The flight made history by breaking the sound barrier three times, reaching a top speed of a bit over Mach 1.1. It is the first privately developed aircraft to break the sound barrier, and the first civilian aircraft to go supersonic over the continental US.

Even more amazing, afterwards, Boom announced that with the right engineering, a sonic boom can refract in the atmosphere and never reach the ground. A boomless Boom! This could enable supersonic flight over the US with only a minor regulatory change. (@bscholl)

Here’s a pic I took of XB-1 getting ready for its historic flight:

See here for a few videos, as well.

Some posts and thread from Blake, both before and after the event:

From others:

News coverage:

Some papers weren’t interested: “We offered pre brief interviews to both WSJ and NYT and invited both to come watch the flight. WSJ said supersonic isn’t newsworthy until the full-scale Overture is carrying passengers” (@bscholl). Which reminded me of this bit from David McCullough’s The Wright Brothers:

Writing his autobiography later, James Cox, publisher of the Dayton Daily News, remembered reports coming “to our office that the airship had been in the air over the Huffman Prairie . . . but our news staff would not believe the stories. Nor did they ever take the pains to go out to see.” Nor did Cox. When the city editor of the Daily News, Dan Kumler, was asked later why for so long nothing was reported of the momentous accomplishments taking place so nearby, he said after a moment’s reflection, “I guess the truth is that we were just plain dumb.”
