From our magazine: GOP legislators repeatedly insisted that “Texas Education Freedom Accounts” would be open to any and all types of private schools—of all creeds and persuasions. In predictable fashion, they haven't quite lived up to that promise.

School Vouchers Are What We Thought They Were
The nascent "freedom accounts" program is, predictably, burdened by Republicans’ insistence on religious discrimination—and likely set to benefit those already outside the public school system.

If this is real, a bit alarming. Earth's magnetic field protects us from all sorts of cosmic nasties. Due to the way the magnetic fieds is generated, it sometimes reverses, weakening in the interim. This study shows that those reversals can be rather long. ⚒️🧪 Link:
