*Subscribing to my substack newsletters or donating through my blog helps to support my independent science and journalism work. I won’t be able to do it for much longer without your help, and I’ll have to start charging for all of my articles. It will make my work inaccessible to those who cannot afford to donate. Critical information must be available, but those who create it must be compensated for their efforts, as they, too, have expenses to pay.
