Canada To Measure Marijuana Use By Testing Sewage

In Canada, Health, International, marijuana, News, NPR, Science on April 13, 2018 at 5:47 pm

In an effort to track cannabis consumption more closely, the Canadian government has instructed Statistics Canada, Canada’s national statistical agency, to analyze sewage waste from about a quarter of Canada’s total 36 million inhabitants.

Predicting Lifespan Based on Size

A fascinating conversation with physicist Geoffrey West about the mathematics of lifespan. “Life is short for small creatures, longer in big ones. So algae die sooner than oak trees; elephants live longer than mayflies, but you know that. Here’s the surprise: There is a mathematical formula which says if you tell me how big something is, I can tell you — with some variation, but not a lot — how long it will live.”
