What's behind this tidal wave of epidemics? In the largest study ever conducted on emerging infectious diseases, we show that the popular explanation - "our relationship with nature is out of balance" - doesn't hold up. Out now in Nature, after half a decade of work: www.nature.com/articles/s41...

New — I had the opportunity to see NAZA, the documentary freaking out the Israeli government because of its horrifying firsthand descriptions of the way the IDF has used AI to target and massacre Palestinian civilians. My thoughts on the film’s damning revelations, and the banality of evil:
thehandbasket.co
I saw the documentary the Israeli government doesn’t want you to see
'NAZA' dispels once and for all the myth that the IDF didn't target civilians in Gaza.
