Sorghum has long been a staple food in many parts of the world, but in the U.S., it’s best known as a sweetener and livestock feed. As demand for the grain soars, so does the amount of waste husks. To reduce this waste, scientists report in the journal ACS Sustainable Chemistry & Engineering a new use for it: a wool dye that can…

But some people pee in swimming pools and hot tubs.
When chlorine reacts with urine, it creates chemicals that can irritate eyes and lungs.
They’ve found a simple way to estimate the volume of urine in a pool.
(Have you ever heard that pool water has a chemical in it that will change color if you pee?
It makes a good marker for pee, says Blackstock.
Liter-sized samples of the city’s tap water contained between 12 and 20 nanograms of Ace-K. (Remember, Ace-K doesn’t decompose during water treatment.)
The smaller pool, though, had 156 nanograms of Ace-K per liter of water.
These pools probably aren’t unusual, says Blackstock.
Caffeine, for instance, can break down after it leaves the body.
Like Blackstock and her team, Escher suggests the best way to tackle urine is pools is prevention, not clean-up.

With a portfolio of well-known water brands and strong distribution, we expect Danone to be in a great position to profit.
The company also has growth opportunities from the infant nutrition market.
Last year in the United States, for the first time on record, sales of bottled water beat out sugar-laden sodas.
Another market which is emerging as a mass-consumer of bottled water is of course China.
During this time the country has doubled its share of global consumption, and in 2013 overtook the US as the biggest market of bottled water by volume.
It’s not just bottled water that we expect to grow strongly in the country.
The $46 billion global infant nutrition market is expected to grow by a CAGR of 8% through to 2020, with the Asia-Pacific region expected to command a 48% share of the market.
When using the company’s OTCQX-listed shares, our target price would translate to being $15.15.
Because of this we think that now would be a great time to make an investment in the space.
I have no business relationship with any company whose stock is mentioned in this article.

“In 2016, bottled water overtook carbonates to become the leading soft drinks category in off-trade volume terms, an astonishing milestone a decade in the making,” it said.
While the fizzy soda category has experienced an annual volume sales decline since 2003, bottled water grew every year over the last two decades, except 2009 during the depths of the Great Recession, driven by consumer concerns about the effects of artificial sweeteners and sugar.
In the four decades since the launch of Perrier water in the U.S., consumption of bottled water surged 2,700%, from 354 million gallons in 1976 to 11.7 billion gallons in 2015, according to the International Bottled Water Association.
Scares over possible water contamination have helped boost demand for bottled water over the last few decades, experts say.
But what people don’t know: When they buy bottled water, they are often times drinking the same water that comes out of the tap.
A spokesman for the International Bottled Water Association says purified and spring water must meet Food & Drug Administration quality standards.
The U.S. was recently ranked 20th among 192 countries that could have contributed to plastic waste in the oceans, according to a 2015 study led by Jenna Jambeck, an environmental engineer at the University of Georgia and published in the academic journal Science.
Still, soda and sugary drinks may lead to an estimated 184,000 deaths each year among adults from diabetes, heart disease and other obesity-related illnesses, according to a landmark 2015 study by researchers at Tufts University published in the American Heart Association journal Circulation.
Several recent studies have linked diet soda and cardiovascular disease and showed a correlation (if not a causation) between cancer and aspartame.
The beverage industry says people who are overweight and already at risk for heart disease may consume more diet drinks in an attempt to control their weight and the Food and Drug Administration has ruled that artificial sweeteners are safe.
