An article found on the Water World website promotes a new film by NASA entitled “Water Falls.” This video will showcase the journey and effect that water has on society.
“Titled “Water Falls,” the video highlights water’s role on Earth as a precious resource that impacts climate, weather, agriculture, urban sustainability, and the natural world. The film also tells the story of the ambitious Global Precipitation Measurement (GPM) space-based research initiative, which will use revolutionary technology and a network of U.S. and international satellites to provide a global picture of rain and falling snow.”
Fluoride is a naturally occurring element that helps to prevent tooth decay. An article found on the American Water Works Association website discusses the Fluoride in drinking water, health, and safety. Since adding fluoride to the water in 1945 child tooth decay has reduced by 20-40%.
“Fluoride’s effect is topical. It keeps the tooth enamel strong by preventing the loss of important minerals.” Fluoride in drinking water is endorsed by American Dental Association, the American Medical Association, and the US Public Health Service.”

A recent article in Scientific American describes how tannins in wine and teas give the beverage its “characteristic pucker”. Scientists, while able to capture finished tannins inside the plant cells, are still unaware of how tannins have formed there in the first place.
“Tannins are a major way plants have of telling herbivores to graze elsewhere. They are deterrents because they denature — that is, deactivate — proteins. Humans have long taken advantage of this denaturing ability to “tan” animal skins with tannins, producing leather. The denaturation of the hide proteins by tannins renders them impervious to bacterial attack — otherwise known as rotting. In plants, tannins may also dissuade microbes and fungi from attacking and help protect plants from damaging UV.”
Tannins in wine come primarily from the grape (the skins, seeds and stems of a wine grape) and the wood barrels the wine is aged in. When referring to wine, tannin adds bitterness and astringency as well as complexity. Because tannins are polyphenols they tend to cling to proteins. This causes tannins to find protein in saliva which in turn gives the inside of the mouth a rough and dry feeling. Although it may seem primarily negative tannins are important to wine by providing structure and flavor complexity.
One can find tannins in a variety of ways, most commonly woody plants such as ferns or persimmons. It can also be found in the tint of lakes and ponds, as stated by the author Jennifer Frazer, “Though the waters were chestnut brown, they were clear. I could easily see the logs and rocks on the bottoms of the ponds.”

We’re pleased to announce the release of edge®, an extraordinary new laboratory meter designed to measure pH, conductivity(EC) and dissolved oxygen (DO).
edge® is incredibly thin and lightweight, measuring only half an inch thick and weighing just 9 ounces. It blends elements of portable meters and bench top meters into a single, seamless design. edge® can be used as a bench top meter, a portable meter, or even attached to a wall to liberate valuable bench space in your laboratory.
In addition to its thin, lightweight design, edge® features a large 5.5” LCD with a wide viewing angle, capacitive touch keypad, dual USB ports, cradle with swivel arm electrode holder and an included wall mount. Continue reading
We’re pleased to announce the release of a new mini automatic titrator designed specifically for the dairy industry.

A recent article in WaterWorld describes how nitrates found in groundwater may take decades to get filtered out. USGS researchers discovered that groundwater nitrate levels were above expected levels, despite the reduction of nitrogen-based fertilizer in the areas tested.
“In this study, USGS scientists closely examined surface and ground waters at seven study sites from across the nation to determine the portion of stream nitrate derived from groundwater… The slow release of groundwater nitrate to streams may also affect the water quality of large rivers. For example, increases in nitrate concentrations during low and moderate flows in large rivers in the Mississippi River Basin have been observed to be greater than or comparable to increases in nitrate concentrations during high flows.”
Nitrate is a naturally occurring form of nitrogen found in soil. It is also often found in fertilizer, since most crop plants require high levels of nitrates to produce high yields. Issues can arise when water runoff carries excess nitrates from agricultural and urban sources Continue reading
