#NASA confirms liquid water flows on Mars NASA has announced that it has discovered flowing liquid salt water on Mars during the Red planet summer months, in
100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water.
NASA/JPL/University of Arizona) ur quest on Mars has been to ollow the water, in our search for life in the universe,
as it appears to confirm that water albeit briny is flowing today on the surface of Mars. he flows are described as recurring slope lineae.
While scientists are yet able to determine where the water comes from, it appears to dry up in the planet fall season only to start up again the following Mars year.
the detection of hydrated salts on these slopes means that water plays a vital role in the formation of these streaks. uring the announcement today,
and now we know there is liquid water on the surface of this cold, desert planet, said Michael Meyer,

#Nestlé Carnation milk plant in drought-hit California to go'zero-water'Switzerland-based Nestlé announced yesterday that work has begun to transform its Carnation Evaporated milk plant in Modesto, California into a'zero water'facility,
Water extracted from milk to produce Carnation Evaporated milk will be used in operational tasks, such as cleaning and cooling."
"This'zero water'approach, where water from the milk is reused would not be appropriate for a bottling plant,
It expects to save nearly 63m gallons of water-approximately 71%of the plant's 2014 water usage-each year at Modesto.
Alongside its'zero water'project at Modesto, Nestlé is ploughing money into technology to reduce the amount of water it uses at its water bottling plants and food and pet care product manufacturing facilties in California.
It has identified potential annual water savings of more than 26m gallons at its Bakersfield and Tulare Dreyer's ice cream plants.
Nestlé has come under fire for its water bottling operations in California, which is into its fourth year of drought.

Nestlé unveiled its first'zero water'manufacturing site in the"water-stressed"Mexican state of Jalisco in October 2014.
Water extracted at the Jalisco plant during the production of Nido powdered milk is used for cooling and cleaning.

or copy was how the insects can jump from the surface of water, leaping just as high off water as they can off solid ground.
For instance, water striders collected from streams and ponds in Seoul, South korea, with bodies a half-inch long can jump more than 3 inches high on average,
"We have revealed the secret of jumping on water using robotics technology,"co-senior study author Kyu-Jin Cho,
"Using high-speed cameras, the researchers analyzed water striders jumping on water. They noticed that the insects'long,
so that the surface of the water did not retreat too quickly and lose contact with the legs.
the scientists found that the maximum force the water striders'legs exerted was always just below the maximum force that water's surface tension could withstand.
The scientists also found that water striders swept their legs inward to maximize the amount of time they could push against the surface of the water
Moreover, the shape of the tips of their legs were curved to adapt to the dimples that formed on the water's surface
the robot could leap about 5. 5 inches off the surface of the water about the length of its body and 10 times its body's height."
"Our small robot can jump on water without breaking the water surface, and can jump on water as high as jumping on land,
"Cho said. The researchers cautioned that, so far, the robot can jump only once, and it lands randomly.
since the weight of the body has to be really lightweight for it to jump on water,

#There's water on Mars, NASA confirms There's water on Mars, and it flows there today.
In an eagerly anticipated news event, NASA revealed this morning the evidence of liquid, flowing seasonal water on the Red planet.
Water often signals life, so this new discovery gives hope to the search for life in our solar system.
Data from various probes and rovers like Curiosity and the Mars Reconnaissance Orbiter have provided researchers with evidence concluding that there is flowing water on present-day Mars. Scientists understand that Mars was once Earthlike with large
amounts of water on the surface. Something unknown happened in the planet's history causing it to change.
However today's revelation confirms that Mars has harbored water in the past, and that water exists there today.
Now, scientists can pursue the implications of what flowing water means in relation to the planet's history
and what it could also mean for the potential for life. Michael Meyer of the Mars Exploration Program at NASA explained,
"We found the active process on Mars today that shows that water was a likelihood."
"He continued with a description of the geological features that caused scientists to suspect water prior to the confirmation of its presence.
To show how researchers came to their conclusions, Meyer explained the significance of"recurring slope linea."
"These RSLS point to the existence of water due to the way they behave. He said,
"There has been no evidence for water until for now.""The news was published based on research today in Nature Geoscience,
Scientists also have an understanding of the composition of the water. Findings show that hydrated salts are present on the surface of Mars. Hydrated salts would mean that the water on Mars is briny.
According to Popular Science, the salt in the water allows it to remain liquid at lower temperatures.
Mary Beth Wilhelm of NASA's Ames Research center explained that the evidence of water means many things,
not the least of which is that microbial life is possible. Also, water on Mars could aid in the human exploration of the planet.
Water on Mars would be a crucial resource for astronauts visiting the planet or for long-term colonists.
Of course scientists will need to study the nature of the water to know the full implications.
Researchers have many exciting challenges ahead of them, and one is to determine where the water comes from.
Could there be an underground Martian aquifer? Researchers note that there is potential for the Curiosity rover to travel to an RSL

#Magnetic Nanosorbents Eliminate Fluoride from Water Researchers from Tehran University of Medical sciences used low-cost and available raw materials for the laboratorial production of nanosorbents with high efficiency in elimination of fluoride from contaminated water.
Presence of high concentration of fluoride in water reservoirs, specially in drinking water, results in serious hygiene concerns.
Adsorption is one of the effective and economic methods to eliminate high concentrations of fluoride from water.
Results showed that the synthesized composite can be used as an effective sorbent to purify water contaminated by fluoride due to its simple and quick separation, high efficiency and the lack of the creation of secondary pollution in the solution.
