Also out today in PNAS: Anwesha Das shows in this thorough paper that "micro-offline gains" in sequence learning do not reflect consolidation of a motor memory - they also happen in random sequences. With @eazanon.bsky.social and Max-Philip Stenner (Magdeburg).

[🆕RESEARCH] Increasing vegetation cover by 10%, 20%, and 30% could lower the global population-weighted mean temperature during the #warm season. These reductions could prevent approximately 0.86, 1.02, and 1.16 million deaths—corresponding to 27.16%, 32.22%, and 36.66% of all heat-related deaths.
