Bill Gates drinks a glass of refreshing water. It wasn't water 5 minutes ago.

This could be the beginning of something huge.

You're about to see Bill Gates drink some water. Clean, delicious, PURE water ... that just happened to be poop five minutes earlier. Yeah, poop!

Would you like to learn how poo becomes drinking water?

And then watch a gabazillionaire drink that water?

I thought so.


We're going to have to talk about poop and science now, so feel free to giggle whenever you need to.

We'll giggle our way to a better world. TOGETHER.

1. Start with the poo, which we'll call "sewer sludge."

2. Burn the water off the poo.

3. Turn the dry poo (or dry sludge) into pathogen-free ash inside an inferno.

4. Process the water vapor, or steam, so it's nice and clean.

5. Make some electricity while you're at it! It's poop-steam-powered electricity, and that's OK.

6.

7. Make some cleany clean drinking water.

Are you thirsty, Bill?


No problem.

If these guys made it...

...Bill's drinkin' it.

The world would be SO different if EVERYONE could just get over the psychological jump it takes to be like, "I'm drinking poop water." So Bill Gates takes the lead.

Diseases caused by poor sanitation currently kill around 700,000 kids a year, so it makes a ton of sense that we'd want to develop safe and affordable ways to get rid of human waste. It'll be a while before we see a processor like this used widely, but it *is* gonna launch in a pilot project in Dakar, Senegal, this year to get it all started. Awesome!

The ultimate goal? To make the processors cheap enough that entrepreneurs in low- and middle-income countries will want to invest in them and then start profitable waste-treatment businesses. It'll save a ton of lives and help kids grow up healthy, all while making profits. Bam! I'm in, are you? You can read more about it all at Gates Notes.

Climate change is happening because the earth is warming at an accelerated rate, a significant portion of that acceleration is due to human activity, and not taking measures to mitigate it will have disastrous consequences for life as we know it.

In other words: Earth is heating up, it's kinda our fault, and if we don't fix it, we're screwed.

This is the consensus of the vast majority of the world's scientists who study such things for a living. Case closed. End of story.

How do we know this to be true? Because pretty much every reputable scientific organization on the planet has examined and endorsed these conclusions. Thousands of climate studies have been done, and multiple peer-reviewed studies have been done on those studies, showing that somewhere between 84 and 97 percent of active climate science experts support these conclusions. In fact, the majority of those studies put the consensus well above 90%.

As a child, Dr. Sangeeta Bhatia's parents didn't ask her what she wanted to be when she grew up. Instead, her father would ask, "Are you going to be a doctor? Are you going to be an engineer? Or are you going to be an entrepreneur?"

Little did he know that she would successfully become all three: an award-winning biomedical and mechanical engineer who performs cutting-edge medical research and has started multiple companies.

Bhatia holds an M.D. from Harvard University, an M.S. in mechanical engineering from MIT, and a PhD in biomedical engineering from MIT. Bhatia, a Wilson professor of engineering at MIT, is currently serving as director of the Marble Center for Cancer Nanomedicine, where she's working on nanotechnology targeting enzymes in cancer cells. This would allow cancer screenings to be done with a simple urine test.

Bhatia owes much of her impressive career to her family. Her parents were refugees who met in graduate school in India; in fact, she says her mom was the first woman to earn an MBA in the country. The couple immigrated to the U.S. in the 1960s, started a family, and worked hard to give their two daughters the best opportunities.

"They made enormous sacrifices to pick a town with great public schools and really push us to excel the whole way," Bhatia says. "They really believed in us, but they expected excellence. The story I like to tell about my dad is like, if you brought home a 96 on a math test, the response would be, 'What'd you get wrong?'"

I live in a family with various food intolerances. Thankfully, none of them are super serious, but we are familiar with the challenges of finding alternatives to certain foods, constantly checking labels, and asking restaurants about their ingredients.

In our family, if someone accidentally eats something they shouldn't, it's mainly a bit of inconvenient discomfort. For those with truly life-threatening food allergies, the stakes are much higher.

I can't imagine the ongoing stress of deadly allergy, especially for parents trying to keep their little ones safe.

The first day of school can be both exciting and scary at the same time — especially if it's your first day ever, as was the case for a nervous four-year-old in Wisconsin. But with a little help from a kind bus driver, he was able to get over his fear.

Axel was "super excited" waiting for the bus in Augusta with his mom, Amy Johnson, until it came time to actually get on.

"He was all smiles when he saw me around the corner and I started to slow down and that's when you could see his face start to change," his bus driver, Isabel "Izzy" Lane, told WEAU.

The scared boy wouldn't get on the bus without help from his mom, so she picked him up and carried him aboard, trying to give him a pep talk.

"He started to cling to me and I told him, 'Buddy, you got this and will have so much fun!'" Johnson told Fox 7.
