Are you familiar with the story of the Antarctica sequences?

Breaking News: Robert F. Kennedy Jr. said he personally instructed the CDC to abandon its position that vaccines do not cause autism. The move underscores his determination to challenge scientific orthodoxy — in this case, that vaccines save lives — and bend the health department to his will.

Update on a significant development NIH grant terms.
On 10/1, a change to grant making regs went into effect that gives NIH more power to terminate grants for policy reasons.
But to use this power, new grant terms must include specific language. See @aniloza.bsky.social w/ the story from July.
