#Signs of liquid water found on surface of Mars, scientists say Despite its reputation as a forebodingly dusty, desolate and lifeless place,
Scientists reported on Monday definitive signs of liquid water on the surface of present-day Mars,
"That's a direct detection of water in the form of hydration of salts,"Mcewen said."
"There pretty much has to have been liquid water recently present to produce the hydrated salt.""By"recently,"Mcewen said he meant"days, something of that order."
Scientists have known long that large amounts of water remain but frozen solid in the polar ice caps.
There have been fleeting hints of recent liquid water, like fresh-looking gullies, but none have proved convincing.
Scientists suspected that water played a critical role in the phenomenon, perhaps similar to the way concrete darkens when wet, with no change in the shape of the surface,
"It's very definitive there is some sort of liquid water, "Ojha said. The perchlorate salts lower the freezing temperature,
and the water remains liquid. The average temperature of Mars is about minus 70 degrees Fahrenheit,
For one, scientists do not know where the water is coming from.""There are two basic origins for the water:
from above or from below,"Mcewen said. The perchlorates could be acting like a sponge, absorbing moisture out of the air,
Liquid water is considered one of the essential ingredients for life, and its presence raises the question of whether Mars,

The opah Lampris guttatus has a global range that includes the southern waters of Australia and swims at depths between 10 and 450 metres.
As the warm blood leaves the core and travels toward the surface of the gills, it transfers its heat to the cold blood that is travelling back from the gills where it has absorbed oxygen from the water.
and says the exchange stops the heat from nearing the gill surface where it would be cooled by the water flow through the gills.

"The fish aren't warming up to the same degree as animals and birds,"says Wegner."

#Innovative Bioelectronic Nose Smells Traces of Bacteria in Water A bioelectronic nose that mimics the human nose can detect traces of bacteria in water by smelling it, without the need for complex equipment and testing.
and it can detect tiny amounts of contamination in water, making it more sensitive than existing detection methods.
There are two main problems caused by bacteria and other microbes in water: they can make the water toxic,
and make it smell bad. At high concentrations, bacteria can be toxic in drinking water. But at lower levels virtually undetectable by current culturing techniques they can cause an ff flavor,
even if the water isn toxic, you don want to drink it. We wanted to develop a way to detect
so people are happy to drink water. raditionally, water was tested for contamination with bacteria by taking a sample
and trying to grow the bacteria in the lab . When the bacteria grow, scientists can count the number of colonies
and calculate the concentration of bacteria in the water. Another approach is to detect the smells directly;
compact device for testing water that is suitable for using on-site. In addition to contamination of drinking water bacteria and other microbes can also contaminate rivers and lakes for example, the algal blooms in Hong kong.
Bacteria that contaminate water give off particular smells that are associated with a handful of smell molecules.
The new nose-like device can detect these smells at very low concentrations of just 10ng per liter of water.
And on top of that was water, into which the scientists injected the molecules that spontaneously form the toxic aggregates."

and therefore clump together to minimize contacts with water, Bertrand explained. From there, these larger aggregates can easily be retrieved through filtration or sedimentation,
with more than 95 percent of the nanoparticles removed from the water. When the nanoparticle loses its protective layer,
polymers are released into the water. While the polymer released (polyethylene glycol) is recognized as safe and used in various food, pharmaceutical and cosmetics products,
Still, even with the small amount of material released into the water Bertrand nanoparticles have compared benefits with current purification processes.

Nanoengineers at the University of California, San diego, have designed enzyme-functionalized micromotors that rapidly zoom around in water,
In their experiments, nanoengineers demonstrated that the micromotors rapidly decarbonated water solutions that were saturated with carbon dioxide.
Within five minutes, the micromotors removed 90 percent of the carbon dioxide from a solution of deionized water.
like a water decarbonation plant,"said Kevin Kaufmann, an undergraduate researcher in Wang's lab and a co-author of the study.
which speeds up the reaction between carbon dioxide and water to form bicarbonate. Calcium chloride which is added to the water solutions,
helps convert bicarbonate to calcium carbonate. The fast and continuous motion of the micromotors in solution makes the micromotors extremely efficient at removing carbon dioxide from water,
said researchers. The team explained that the micromotors'autonomous movement induces efficient solution mixing, leading to faster carbon dioxide conversion.
To fuel the micromotors in water, researchers added hydrogen peroxide, which reacts with the inner platinum surface of the micromotors to generate a stream of oxygen gas bubbles that propel the micromotors around.
When released in water solutions containing as little as two to four percent hydrogen peroxide the micromotors reached speeds of more than 100 micrometers per second.
As a next step, researchers are planning to make carbon-capturing micromotors that can be propelled by water."

The invention could pave the way for the development of'flying submarines'-vehicles that can seamlessly travel through air and water

'Through various theoretical, computational and experimental studies, we found that the mechanics of flapping propulsion are actually very similar in air and in water,
'In order to make the transition from air to water, the team first had to solve the problem of surface tension.
The Robobee is so small and light it couldn't break the surface tension of the water at first.
But the researchers worked out a way of making it hover over the water at a certain angle,
By doing this, the Robobee is able to crash into the water in a controlled way and sink.'
'Water is almost 1, 000 times denser than air and would snap the wing off the Robobee
The team prevented the Robobee from short-circuiting in the water by coating the electrical connections with glue.
It also only currently swims in deionised water. Another drawback, is that as yet, the robot can't make the transition from water to air,
because it can't generate enough lift without snapping one of its wings. Solving this issue is the next challenge.'
'In tests, the grooves in the e skin were able to respond to water droplets running across them
