A new study, published Thursday in Environmental Health Perspectives, adds more evidence to the idea that e-cigarettes aren't an entirely risk-free endeavour. It suggests that the very act of vaping might be exposing people to unsafe levels of toxins like lead and arsenic.

Earlier this week, a storm spawned by the former Cyclone Gita swept across New Zealand, damaging buildings, knocking out electricity and creating floods. But along the Rakaia River, the storm triggered a bizarre natural phenomenon known as granular flow - essentially a raging river of rocks.
