Electric vehicles require very large lithium batteries – some even believe Tesla is more a battery than a car company. In any event, as an article in Wired points out, no good deed goes unpunished. What do we do with batteries at the end of their life?
A new study finds that if you vape and then quit, you're more likely to suffer a fracture than if you currently vape. The authors say their results suggest that e-cigarettes pose a risk to bone health. What sense does that make? Very little. Let's take a closer look at the paper.
