Removing all the dangerous bacteria from drinking water would have enormous health benefits for people around the world.
The technologies exist for doing that, but there’s a problem: cost.
Now MIT’s Rohit Karnik thinks he’s on to a much less expensive way to clean up water: Use the xylem of a plant.
Now if you remember your high school biology, you’ll know that xylem is the stuff in plants that transports water in the form of sap from the roots to the leaves.
"And the way the water is moved is by evaporation from the leaves," says Karnik.
It’s somewhat like what happens when you put a straw into a glass of liquid. Evaporation from the leaves has the same effect as sucking on the straw.
Pulling water up to the leaves this way creates a problem for the plant, but also an opportunity for an inventor.
The plant’s problem is something called cavitation, or the growth of air bubbles, which makes it harder for water to reach the leaves. But Karnik says xylem has a way of getting rid of these bubbles.
"The xylem has membranes with pores and other mechanisms by which bubbles are prevented from easily spreading and flowing in the xylem tissue," he says.
And it turns out these same pores that are so good at filtering out air bubbles are just the right size for filtering out nasty bacteria.
To prove it worked, he created a simple setup in his lab. He peeled the bark off a pine branch and took the sapwood underneath containing the xylem into a tube. He then sent a stream of water containing tiny particles through the tube and showed that the wood filter removed them.
"We also flowed in bacteria and showed we could filter out bacteria using the xylem," he says. Karnik estimates the xylem removed 99.9 percent of the bacteria.
The results were published Wednesday in the journal PLOS ONE.

The FDA proposes improved nutritional labels on food to make the information more understandable and selecting healthier choices easier.

Five Reasons to Vote Out Louisiana Rep Steve Scalise
1. Well that’s a solid argument.
2. Solid arguments are this guy’s thing, eh?
3. American by birth? Nope.
- Just because Steve Scalise got his citizenship through birth doesn’t mean he believes others should.
4. You should fight for your country….unless you’re gay.
5. Well, violence isn’t that bad, amirite?
This is exactly why I will never give American Apparel a single penny.
Not only does the founder have a history of raping female employees (some of them teens), masturbating in front of female reporters, harassing female employees, promoting sexism, and promoting pedophilia, but it seems they’ve now gone to straight-up advertising with pornography which appear to be creeper shots.
The above is an actual advertisement they posted on their tumblr page.
I had to blur it out because that is not even remotely SFW.
The original link is posted in the source. I don’t recommend you click it.
American Apparel needs to be held accountable for their crimes against women, and particularly the founder, needs to be put in prison for rape and pedophilia, among other things.
These bastards will never get any of my money.
