How to monitor urine in pools, by testing sweetness
Date: March 1, 2017 Source: American Chemical Society
Even though Olympic swimmers have admitted doing it, peeing in the pool is not a condoned practice. Urine contributes to the formation of compounds in pool water that can be harmful to people's health. Now scientists are tackling a new way to monitor water quality: by measuring how sweet it is. Their report appears in ACS' journal Environmental Science & Technology Letters.
Recent studies have shown that nitrogenous compounds (e.g., urea) in urine and sweat react with chlorine to form disinfection byproducts (DBPs), including trichloramine, that can cause eye irritation and respiratory problems. Xing-Fang Li, Lindsay K. Jmaiff Blackstock and colleagues say this evidence has highlighted the need for improved understanding of pool chemistry to raise awareness and educate the public on the importance of swimming hygiene practices. To estimate how much urine -- and potentially DBPs -- might be in a given pool, Li's team needed to identify what compound might consistently be present in urine. So the researchers turned to the artificial sweetener, acesulfame potassium (ACE), which is marketed as Sunett and Sweet One. The sweetener, which is often used in processed foods like sodas, baked goods and even in other sweeteners, is widely consumed, chemically stable and passes right through the digestive tract and into consumers' urine.
The researchers developed a rapid, high-throughput analytical technique to test more than 250 water samples from 31 actively used pools and hot tubs in two Canadian cities, and more than 90 samples of clean tap water used to initially fill the basins. The concentration of ACE in the pools and hot tubs ranged from 30 to 7,110 nanograms per liter of water -- up to 570 times more than the levels found in the tap water samples. Based on the concentrations of the sweetener, the researchers estimated that swimmers released more than 7 gallons of urine -- enough to fill a medium-size trash bin -- in a 110,000-gallon pool in one instance, and nearly 20 gallons in a 220,000-gallon pool (one-third the size of an Olympic-size pool) in another instance. ________________________________________ Story Source: Materials provided by American Chemical Society.

I WORKED AT THE AMERICAN CHEMICAL SOCIETY IN WASHINGTON DC YEARS AGO. GREAT PEOPLE! BUT I REALLY DON'T WANT TO TEST THE POOL WATER. I DON'T WANNA KNOW!

GOOD MONDAY MORNING LOVELY PEOPLE
Astronaut-Like ‘Humanoid’ Photographed in Scotland
Posted on Mar 5 2017 - 4:12pm by Cryptozoology News
SCOTLAND– A man in the west central Lowlands of Scotland said he captured the image of an “unknown entity”.
The anonymous man says he was walking through the forest with his nephew when he took the photograph.
“We were on the way back down from Windy Hill in Renfrewshire,” he said. “I decided to take a photo of my nephew, who had just walked in front of me.”
The photographer claims that he felt as if “someone was near”.
“It was a strange feeling, but I didn’t notice anyone.”
When they returned home and uploaded their photos onto their computer, he added, he noticed the anomaly right away.
“There were one or two entities… what looked like small people peering out from the tree next to my nephew,” he reported.
The picture shows his nephew as he walks down a brown path between the trees and an unidentified white shape to his left that resembles a small and fully dressed astronaut. The humanoid appears to be walking towards the left side of the woods.
The man says he is sure they didn’t see anything of that shape and color in the area at the time the picture was taken, back in 2015. The camera model used to take the picture wasn’t provided and initial EXIF analysis are unable to reveal positive doctoring.
In 1980, a series of UFO incidents in the Rendensham Forest, England, grabbed the world’s attention in what some ufologists now catalog as the British Roswell.

GOOD MORNING ALL
THAT BLACK CUBE IS KINDA CREEPY Z

FOX News analyst Catherine Herridge went on with Tucker Carlson to discuss the unprecedented Deep State leaks on General Mike Flynn. Herridge said this was a top level Deep State leak. Only a select few had access to this information.
"The first full part of the series, "Year Zero", comprises 8,761 documents and files from an isolated, high-security network situated inside the CIA's Center for Cyber Intelligence in Langley, Virgina. It follows an introductory disclosure last month of CIA targeting French political parties and candidates in the lead up to the 2012 presidential election.
Recently, the CIA lost control of the majority of its hacking arsenal including malware, viruses, trojans, weaponized "zero day" exploits, malware remote control systems and associated documentation. This extraordinary collection, which amounts to more than several hundred million lines of code, gives its possessor the entire hacking capacity of the CIA. The archive appears to have been circulated among former U.S. government hackers and contractors in an unauthorized manner, one of whom has provided WikiLeaks with portions of the archive.
"Year Zero" introduces the scope and direction of the CIA's global covert hacking program, its malware arsenal and dozens of "zero day" weaponized exploits against a wide range of U.S. and European company products, include Apple's iPhone, Google's Android and Microsoft's Windows and even Samsung TVs, which are turned into covert microphones."
