Collisions with electrons cool molecular ions
A lone molecule free in cold space will cool by slowing down its rotation—it will spontaneously lose its rotational energy in quantum transitions, typically only once in many seconds. This process can be accelerated, slowed down, or even inverted b.....»»

In February 2024, a research article titled "Pumpkin CmoDREB2A enhances salt tolerance of grafted cucumber through interaction with CmoNAC1 to regulate H2O2 and ABA signaling and K+/Na+ homeostasis" was published by Professor Zhilong Bie's team from.....»»
Solar geoengineering to cool the planet: Is it worth the risks?
When I first wrote about geoengineering in 2012 , it was considered far-fetched at best, and crazy by most. But 12 years later, while there is still controversy and considerable resistance to deploying it, respectable scientists and institutions are.....»»
