“Take 36-year-old Nick Keith, who remains $142,000 in debt eight years after graduating from culinary school.” —

This Bright-Eyed Young Man Was Utterly Demolished by Student Loans

I think you mean “dim young man in some financial difficulty due to bad life choices, made against the advice of those who tried to help” there:

Keith’s father only agreed to co-sign a student loan if he stuck with an engineering degree at Iowa State University, but even with decent grades, he knew it wasn’t a right fit.

$142,000 in debt for a one-year degree in cooking school? And not even at the C.I.A.!

“Researchers at NYU School of Medicine have, for the first time, identified a single gene that simultaneously controls inflammation, accelerated aging and cancer.” —

Key gene found responsible for chronic inflammation, accelerated aging and cancer | e! Science News

Here’s hoping they’re right, and that gene therapy results from this. (And that the various government/nonprofit busybodies keep out of the way of medicine.)

“Students assigned randomly to statistics courses that relied heavily on “machine-guided learning” software — with reduced face time with instructors — did just as well, in less time, as their counterparts in traditional, instructor-centric versions of the courses.” —

Report: Robots stack up to human professors in teaching Intro Stats | Inside Higher Ed.

Extremely unsurprising: statistics, like much technical material, is a practice. You learn it in the lab not in the lecture. As long as there’s motivation (a/k/a testing and grading), access to computers, and a good textbook, instructors are necessary only for clarification.

That experiment should have had “textbook only” as a third condition. But there’s always the lure of technology.
