Drinking more water associated with numerous dietary benefits, study finds

For people who want to control their weight or reduce their intakes of sugar, sodium and saturated fat, tap water may be what the doctor ordered.

A new study that examined the dietary habits of more than 18,300 U.S. adults found the majority of people who increased their consumption of plain water — tap water or from a cooler, drinking fountain or bottle — by 1 percent reduced their total daily calorie intake as well as their consumption of saturated fat, sugar, sodium and cholesterol.

0001People who increased their consumption of water by one, two or three cups daily decreased their total energy intake by 68 to 205 calories daily and their sodium intake by 78 to 235 milligrams, according to a paper by University of Illinois kinesiology and community health professor Ruopeng An. They also consumed 5 grams to nearly 18 grams less sugar and decreased their cholesterol consumption by 7 to 21 milligrams daily. Read more

Water on Mars Had Unpleasant Taste Most Likely

gale_craterSpecialists of the Open University and the University of Leicester (UK) studied the past of the Red planet and found that water existed in the Gale crater for a long time. And if the earthman had the opportunity to taste it, it would be unlikely he liked. Read more

Clean energy from water

Fuel cells generate electrical energy through a chemical reaction of hydrogen and oxygen. To obtain clean energy, the splitting of water into its components of hydrogen and oxygen is critical. Researchers at the University of Basel study how sunlight can be used for this purpose. The scientific journal Chemical Communications published their latest results.

earth-day-nailDeveloping clean and renewable sources of energy is one of the greatest challenges of our civilization. Artificial photosynthesis is one of the most promising approaches. This is when water is photo-electrochemically with the aid of sunlight separated into its components H2 and O2 and stored. When the chemical elements are later combined, electrical energy can be created. A team of researchers led by the University of Basel chemists Catherine Housecroft and Edwin Constable are working together with the Swiss Federal Laboratories for Materials Science and Technology (Empa) to implement this method.

Is Asia’s water supply in trouble?

Based on a series of simulations ran through sophisticated computer models, researchers from MIT are highlighting the possibility that a significant percentage of the population of Asia could suffer severe water shortages by the year 2050. As a basis for the study, the team made use of a pre-existing MIT-generated computer model designed to simulate Asia’s complex economic, climate, and growth characteristics. A detailed water-use model known as a Water Resource System was then introduced, and the team ran a number of simulations aiming to cover the widest range of potential scenarios.

According to the study, an extra one billion people living in Asia could experience water stress by the year 2050

Each of the simulations tested the key variables by holding steady one or more of the factors while allowing another, such as population growth, to increase in line with predicted numbers. Each of the scenarios also accounted for, amongst a host of other factors, the interconnected nature of the water supply in the affected regions. For example, if climate change or any other contributing element causes the water basin at the top of a network to go unfilled, other basins further down the network that would ordinarily be fed by the primary basin suffer in kind.

SteriPen’s UVR tech amplifies UV rays to speed up water purification

There are many ways to filter and purify water out in the wild, the MSR Guardian and Oasis being a couple of the most recent we’ve looked at. Since 1999, Hydro-Photon has gone with ultraviolet light, offering lightweight, compact SteriPen purifiers that quickly zap away microorganisms. With its new Ultraviolet Reflection (UVR) technology, it makes the UV purification process even faster, so outdoor enthusiasts can get clean water more efficiently than ever.

The SteriPen Emergency+ kit will come with both 2- and 4-L water containers

The SteriPen Emergency+ kit will come with both 2- and 4-L water containers

UVR kits pair SteriPen portable, battery operated purifiers with soft RapidUVR water bottles. The bottles feature a proprietary reflective coating that amplifies and contains the UV rays from the purifier, speeding the process enough to purify up to 4 liters of water in 90 seconds, compared to 1 liter/90 seconds when a SteriPen is used without a UVR bottle.
