Catchy, clear, concise: three-part phrases in research-paper titles garner more citations.
Nice to know that the 'rule of three' also works for science articles. Could get irritating if over-used?

πΆ When it comes to making sense of data, visualizations rule. But what about translating data into sound? In today's blog post, @lutzb.bsky.social explores 'data sonification' and its many applications and shows: even bibliometric data can be turned into sound.
