I’m very glad I got to write about 28 Years Later for @cenmag.bsky.social just in time for the Jan release of the next chapter 😆
Looking for a fun read? For the December #Newscripts in @cenmag.bsky.social, Fionna Samuels (@fmorningstar.bsky.social) took a look at the chemistry of two pop culture moments from the past year: An exoplosive scene in 20 Years Later and the GBBO sugar dome disaster

So, remember that MAHA summit 2 weeks ago that @statnews.com broke the news of and @maxkozlov.bsky.social somehow got into for Nature, even though it was closed to the press?

Do you have recipe books with annotations and stains on the most popular pages? Me too, and so does the University of Manchester. Except their recipe books are medieval medical manuals.

There’s a lot of historically and culturally significant stuff captured on audio (and video) tape. But tapes are mass-market items that weren’t made with long-term archiving in mind.
