Insightful and worthwhile correspondence regarding xenon use in high altitude mountaineering by prof. Burtscher in @NEJM Xenon — Propelling Climbers to the Summits of the World’s Highest Mountains? nejm.org/doi/full/10.1056/NE…

Xenon — Propelling Climbers to the Summits of the World’s Highest Mountains? | NEJM

Although xenon may have neuroprotective effects, there is no strong evidence that it aids in short-term, high-altitude performance. Success is more likely a result of acclimatization, oxygen suppor...

The pressure to publish in high-impact journals is often at the expense of other scholarly activities go.nature.com/3XjPgjv

Move beyond ‘publish or perish’ by measuring behaviours that benefit academia

Nature - A standardized system to measure contributions in mentorship, collaboration and more could bring about systemic change in science.
