New Generation of Cheap Water Filters: Inspired by Nature!

MIT engineers are testing out new and cheap ways to filter water, and all you need is a stick! Costly manmade filters are reliable, but unaffordable for the developing world. That's why scientist Rohit Karnik is testing out the technology beneath the bark of an ordinary tree!

According to Time, "The branch’s vascular system contains membranes designed to filter out microscopic air bubbles. Karnik found that those same membranes could filter out harmful bacteria as well, apparently as much as 99.9%." If you've ever heard of a tree's xylem, that is what he is talking about.

The possible health risks have not been confirmed, but there is no doubt we're taking filtration in a whole new direction!
