Different types of scientific creativity correlate with time in the field…interesting read!

[James Evans @profjamesevans]

Out today in @ScienceMagazine: with the amazing Haochuan Cui, Yiling Lin, & @LingfeiWu, we analyzed 3.6 million scientists publishing 1960–2020. The findings reshape a century-old debate about age and scientific creativity.

Want more citations?

Publish something wrong or nonreplicable and let the whole academic community correct you.

I've plotted the most expensive McDonald's burger and the least expensive MacBook over time. This analysis projects that the most expensive burger will be more expensive than the cheapest laptop as soon as 2081

@IsevOrg's highly cited Minimal Information for Studies of Extracellular Vesicles (MISEV) has become the leading authoritative resource for advice across #EV workflows. This is largely because #MISEV has been built by many, many contributors who have generously shared their knowledge and views.
Two years after the appearance of the current MISEV document, where is the field? Is a new MISEV needed? If you are interested in EVs, ISEV would love to hear your views. Please complete this survey by March 3, 2026.

Luminal cargo delivery by EVs is the reigning paradigm for EV communication. Could surface activity be just as important? At this week's #EVClub, Martina Fabiano, Alan Adamczyk, and Matias Ostrowski present "Plasma EV surface-located GAS6/PROS1 and CD39/CD73 attenuate inflammation"
