Update: it appears that these are actually the previously announced Neuroscience cutbacks taking effect – some reports I’d received made it sound as if this were something new. I’ve changed the title of the post to reflect this.
I’ve heard from more than one source that Pfizer is making fairly broad cuts in research staffing (particularly on the biology end) as of yesterday and today. The company has made no announcement, so details are scant, but I’ll update them as things become more clear.
