Now some say its time for scientists themselves to take direct action.

New preprint by @GilYardeni "The explosive radiation of the Neotropical Tillandsia subg. Tillandsia (Bromeliaceae) has been facilitated by pervasive hybridization." 👏

We used whole-genome reseq data of 34 Tillandsia sp and observe high rates of hybridization within and among clades, which could have facilitated this radiation.
In addition to all the phylogenomic work (figs in the main text), don't hesitate to have a look at the SI (e.g. introgression footprint on chr18)
Researchers looked for most influential voices in the discourse about Israel–Hamas war on X
They found that 7 accounts, many unknown a yr ago, were racking up 100s of mill. of views/day, out-performing standard news accounts by an order of magnitude and exercising significant influence on the discourse around the war
Elon Musk had interacted with or explicitly recommended 6 of those posters, potentially bringing them to the attention of his 162 mill. followers
