AI 两周内修复、教学与发现：从胰腺癌早筛到 10,091 颗新系外行星候选体

This Week's Sign the Apocalypse Isn't Upon Us

AI 导读

AI 在近两周内于医疗、教育、农业、天文和灾害响应领域取得多项进展：Mayo Clinic 验证的 AI 可在常规 CT 扫描中提前最多 3 年检出胰腺癌，强生称 AI 将新药研发先导化合物生成时间减半、临床试验报告准备从 700 小时压缩到约 15 分钟。

In short : From early cancer detection to teacher training and exoplanet discovery, AI is quietly fixing real problems. Here are the good things it accomplished in just two weeks.

I remember growing up reading Sports Illustrated. There was a small column called “This Week’s Sign the Apocalypse Is Upon Us.”

With all the dire predictions about AI, it’s important to also spend time recognizing the tremendous pace of innovation & the impact AI is having broadly. Here’s what it fixed, taught, and discovered in the last two weeks.

In medicine

  • Mayo Clinic validated an AI that detects pancreatic cancer up to 3 years before diagnosis on routine CT scans.1
  • J&J reported AI is halving the time to generate new drug development leads and cut clinical trial report preparation from 700 hours to about 15 minutes.2

In classrooms

  • A 2025 Harvard physics study found students using AI tutors learned more than twice as much in less time compared with traditional active learning classrooms.3
  • Thailand upskilled 160,000 teachers in AI, impacting 3.3 million students.4

On land

  • Texas A&M demonstrated AI predicting outbreaks of destructive crop pests with ~88% accuracy in open fields.5

In the stars

  • Princeton researchers used AI to scan 83 million stars from NASA’s TESS telescope data and identified 10,091 new exoplanet candidates (11,554 total), sorting in seconds what would take astronomers years by hand.6

In disaster response

  • Hong Kong launched an AI flood forecasting system with 3D simulations, enabling faster preemptive emergency responses.7

Reversing the SaaSpocalypse

  • Atlassian reported Q3 FY26 revenue of $1.79 billion (up 32% year over year), with cloud revenue surging 29% to $1.13 billion. The company raised its full year growth outlook to ~24% from 22%, and shares soared more than 25%.8
  • Twilio posted Q1 2026 revenue of $1.41 billion (up 20%), its highest revenue and gross profit growth rates in more than three years. The company raised its full year forecast.9

Clearly, there are many risks associated with AI, & it’s important to counterbalance them with some of the tremendous advances that are happening every week.
