Who Were the Luddites? They were part of a labour movement that emerged in the textile districts of England in the early 16th century. They were not saying “We don't want the machines.” They were saying:  “Not on these terms.” benton.org/blog/what-would-l… #Luddites #history #politics

What Would the Luddites Make of Digital Opportunity?

The Luddites understood that technological change had terms. Their fight was over who would set those terms.

Earth's length of day swings a few milliseconds over 60 to 70 years, and a 2026 Nature study ties it to the inner core's gravitational pull on the mantle

The risks of using generative Artificial Intelligence in education outweigh the benefits. That’s the warning in a seminal report from the Brookings Institution’s Center for Universal Education.   eschoolnews.com/digital-lear… via @eschoolnews #AI #SciEd #education #science #SciChat

AI is stealing students’ ability to think critically--Journalism 101 may be an antidote 

Responsibilities that require human discretion and knowledge shouldn’t be trusted completely to AI--we need critical thinking skills.

Study: Sex chromosomes drive how bodies deal with cancer, heart health and longevity

New research shows that X and Y chromosomes drive risk of diseases, including cancer, independent of hormones. Understanding these mechanisms could drive sex-aware medicine.
