Interesting news: The Marine Biological Labs at Woods Hole (MBL) is once again becoming an independent institution. University of Chicago will remain a partner, but only one of many. MBL is an amazing place for science and science training and I hope it will thrive in this new status.

Bhattacharya cited no studies, no analysis, except his belief that vaccination rates will go up as they paradoxically remove vaccines from the childhood schedule.

if the whole genocide thing wasn't enough for you, another good reason to get AIPAC money out of democratic politics is that the organization now exists to move republican donor money into democratic races to sow chaos and get the most republican-friendly democrat elected
Punchbowl has AOC quoted saying the same thing that I've been saying for the past few weeks re: AIPAC spending against pro-Israel Tom Malinowski.
“It’s quite shocking how moderate of a stance that they are mobilizing against. We’re not even talking about them targeting the left,” Ocasio-Cortez said

AIPAC’s first 2026 test
A Thursday special primary election will reveal whether Malinowski can survive a spending onslaught in a new era of anti-AIPAC sentiment among Dems.
