Socioeconomic roots of academic faculty
Tenure-track faculty are up to 25 times more likely to have a parent with a Ph.D. Moreover, this rate nearly doubles at prestigious universities and is stable across the past 50 years.

I wrote my new Nature World View in this transition — one last reflection before leaving Colombia. It explains why inequities persist in science, even when dressed up as inclusion, and why we must stop mistaking access for change. 👉 rdcu.be/eGEun
Equity in science is a beautiful lie — and I’m done pretending | Nature
Science isn’t really moving towards equity; institutions are just perfecting the appearance of equity. We need to build an alternative system. Science isn’t really moving towards equity; institutions are just perfecting the appearance of equity. We need to build an alternative system.

Testing ecophysiological theory using tree traits along a vapour pressure deficit (VPD) gradient shows, as predicted, that photosynthetic capacity is higher at higher VPD sites. Contrary to the predictions, potential water conductivity tends to increase with higher VPD. doi.org/10.1038/s420...

Tree methane exchange in a changing world
Nature Reviews Earth & Environment, Published online: 19 June 2025; doi:10.1038/s43017-025-00692-9Tree methane exchange is an important component of the terrestrial and global methane budget. This Perspective explores the mechanisms underlying why wetland trees are a net source of methane to the atmosphere and upland trees are a net sink, and the effect environmental changes will have on these processes.
