Water Found on the Moon
As they say, the third time is the charm. Three different missions to the moon have relayed back evidence of water. There were traces of water in the moon rocks brought back by Apollo, but that was attributed to contamination. Three more recent examinations have found evidence of water: India’s Chandrayaan-1 probe detected water by mapping wavelengths of light from the moon’s surface, the Cassini probe found evidence of global distribution of the water signal, and the Deep Impact spacecraft found evidence by infrared detection.
“The Deep Impact observations of the Moon not only unequivocally confirm the presence of [water/hydroxyl] on the lunar surface, but also reveal that the entire lunar surface is hydrated during at least some portion of the lunar day,” the authors wrote in their study.
The findings of all three spacecraft “provide unambiguous evidence for the presence of hydroxyl or water,” said Paul Lucey of the University of Hawaii in an opinion essay accompanying the three studies. Lucey was not involved in any of the missions.
The new data “prompt a critical reexamination of the notion that the moon is dry. It is not,” Lucey wrote.
The amount of water on the moon is miniscule by Earth standards, with one ton of lunar surface holding about 32 ounces. Link -via Digg

Eco-Friendly Steam Dishwasher
Washing dishes in a full-loaded dishwasher without pre-rinsing saves water (particularly expensive hot water) over washing by hand. This steam dishwasher designed by Vincent Liew saves even more water and energy!
As the title suggests, this dishwasher uses pressurized steam to dislodge food particles on dishes and sanitize them. A hearty rinse after the cleaning process gives you squeaky clean dishes!
Now for the Eco-friendly part. Since no detergents are used, there is less of “ozone depleting solvents” going around. The water used in the steam and rinsing is collected in the recycling bay and using “Membrane Technology” (read more info on this here), the grime and food particles are separated from the water. The clean water is recycled to be used again for the next wash.
Contaminated water, too harsh for reusing is discarded via an outlet and only then is a fresh load of water consumed.

The Lucky Luke Effect: How Zooplanktons Eat in a Vast Ocean
Stop and think about this for a second: how does a zooplankton eat in such a vast ocean? Turns out, it’s not a trivial task: copepods, a type of zooplankton, filter a volume of water approximately 1 million times their own body volume to survive every day … and at their scale, water has the consistency of syrup.
Scientists discovered a particularly interesting "ambush feeding" technique dubbed the Lucky Luke effect:
“So far, we know of four ways in which zooplankters tackle the engineering feat of finding food in water which appears as thick as syrup. Our contribution has been to describe the mechanism at work for the last of these: How some copepods perform spectacularly precise and rapid surprise attacks on their single-cell prey after first having registered the prey by means of hydrodynamic signals,” explains Professor Thomas Kiørboe, DTU Aqua.
The solution for the ambush-feeding copepods builds on what Thomas Kiørboe calls the Lucky Luke effect:
“Our recordings show that the sub-mm copepods accelerate to a speed of 100 mm per second in a few milliseconds, while at the same time rotating perhaps 180 degrees. Like Lucky Luke who is faster than his shadow, the copepods jump forward so rapidly and with such precision that they, so to speak, shake the viscous boundary layer off, in that way getting close enough to their prey to capture it with their feeding limbs.”
The viscous boundary layer is the layer of water which the copepods pull with them when moving their bodies through the syrupy water. The larger the animals are and the faster they swim, the thinner it seems.

DIY Floating Water Bike
Humans may not be able to walk on water, but an invention by Li Weiguo let us bike on water! Behold the amphibious bicycle, made by water containers jerry-rigged into pontoons:
Li Weiguo’s daughter Li Jin rides the human-powered amphibious bicycle on the water in Wuhan of Hubei Province, China on May 30, 2009. The amphibious bicycle made by Li Weiguo is equipped with eight water buckets as pontoons and adjustable vane wheels as driving power. This kind of bike can walk on land and on water.

Liebherr R9800 Excavator Car Wash
[YouTube - Link]
This short video clip shows why it’s a bad idea to get your car washed with a Liebherr R9800 Excavator.
If you’re curious, the shovel has a capacity of 42 cubic meter (which when filled with water, is equivalent to 42 metric ton or oh, about 92,500 lb). Explains the end result, doesn’t it?

Poo-Man on the Fourth Plinth
Sculptor Antony Gormley of One & Other’s summer art project is loads of fun: he asks the people of London to occupy the empty Fourth Plinth in Trafalgar Square, usually reserved for statues of kings and generals. Every hour, 24 hours a day for 100 days, a different person will become their own living sculptures on the Fourth Plinth.
This guy to the left is aquatic scientist Oliver Parsons-Baker, who came up dressed as a giant poo. He’s trying to raise awareness and promote better sanitation around the world with Water Aid:
The 26-year-old, who works for Severn Trent Water, has teamed up with Water Aid to raise awareness of the billions of people trapped in the poverty cycle due to a lack of safe water and toilets.
His cumbersome costume meant he had to be hoisted onto the plinth, drawing laughter and applause from the crowd. The outfit was composed of brown foam and leather, with a sizeable housefly dangling from it.
Parsons-Baker got his message across via two placards which bore the message: "2.5bn people don’t have a toilet" and "G8 leaders – take action on the sanitation crisis now".

Huge Mars Region Shaped by Water
Shifting sand dunes on ancient Mars once concealed a network of underground water spread across an area the size of Oklahoma, according to new findings from NASA’s Mars rover Opportunity.
The new findings confirm suspicions that water once shaped the Martian landscape on a regional scale instead of forming isolated oases, said rover project leader Steven Squyres of Cornell University in New York State.

Floating Water Bridge
[YouTube - Link]
The floating water bridge is a weird phenomenon discovered by Elmar Fuchs and colleagues from the Graz University of Technology in Austria, in which, with the help of electricity, water can actually create a floating bridge as long as 25 millimeters.
From PhysOrg:
When exposed to a high-voltage electric field, water in two beakers
climbs out of the beakers and crosses empty space to meet, forming the
water bridge. The liquid bridge, hovering in space, appears to the
human eye to defy gravity.
Upon investigating the phenomenon, the scientists found that water
was being transported from one beaker to another, usually from the
anode beaker to the cathode beaker. The cylindrical water bridge, with
a diameter of 1-3 mm, could remain intact when the beakers were pulled
apart at a distance of up to 25 mm.
Why water would act this way was a surprise, Fuchs told PhysOrg.com.
But the group’s analyses have shown that the explanation may lie within
the nature of the water’s structure. Initially, the bridge forms due to
electrostatic charges on the surface of the water. The electric field
then concentrates inside the water, arranging the water molecules to
form a highly ordered microstructure. This microstructure remains
stable, keeping the bridge intact.

Water Footprint
Biggify here: Link
Forget carbon footprint. Long before the Earth will suffer from a climate catastrophe due to global warming, humanity may perish from another environmental disaster: the diminishing supply of fresh water (Don’t believe it? Why, humans have been fighting wars over water for centuries)
In collaboration with Fogelson-Lubliner, GOOD Magazine has an eye-opening infographic of "water footprints", the amount of water an individual uses in the course of a day, as well as ways to save water by making simple changes in your habits.
I, for one, am surprised at the amount of water it takes to yield a pound of beef: Link – via swissmiss

Flammable Water
Normally, you’d fight fire with water, but not at Jesse and Amee Ellsworth’s home. They have so much natural gas, leaking from nearby gas wells, in their water that they can light it on fire!

Venice From Above
Absolutely stunning pictures of Venice taken from the air. The ‘city of water’ is located in northern Italy, spanning 118 islands in the Venetian Lagoon. If I didn’t know these pictures were real, I’d assume I was looking at shots from a new videogame or a medieval version of Waterworld.

Water-Loving Cat
Cats hate water, right? Well, the old stereotype doesn’t seem to apply to USA Today Pet Talk columnist Sharon Peter’s Grisabella. Meet the cat that LOVES to play in water!
The old "cats hate water" stereotype may be true much of the time (especially at forced-bath time), but mine isn’t the only feline in America that seeks out moments of wetness, I now know (having investigated this matter in hopes of learning she is so rare that starring roles in pet movies, or at least cat food commercials, might be possible).
There’s a breed called the Turkish Van that loves water, and many of them are avid swimmers; lots of owners of Bengals (the cat, not the tiger) report that their felines are water babies, too. And, I learned, you can even find cats-swimming videos on YouTube, action footage that proves it’s not just pedigreed cats that enjoy the occasional dip.
And sure enough: there are a lot of swimming cats on YouTube

Liquid Water Found on Mars!
Here’s some good news for all the space buffs out there: NASA’s Phoenix lander may have captured the first images of liquid water on Mars. Photographs appear to show water droplets that splashed onto the craft’s leg during landing.
“The controversial observation could be explained by the mission’s previous discovery of perchlorate salts in the soil, since the salts can keep water liquid at sub-zero temperatures. Researchers say this antifreeze effect makes it possible for liquid water to be widespread just below the surface of Mars, but point out that even if it is there, it may be too salty to support life as we know it.”

7 Symbiotic Wonders of the Seven Seas
So how did we get here anyway? Call it evolution, call it luck, but really the best and brightest creatures above and below the waves found powerful allies. In some cases these are completely unexpected – predator and prey, friend and foe – but the ones that stuck it out and stayed friends through the toughest of times managed to make it to today’s oceans and seas.
Evolution alone is an amazing thing – but species that evolve together can be all the more spectacular, protecting, feeding and cleaning one another in incredible ways. Sharks pair with fish, fish with shrimp and shrimp with sea cucumbers and much much more. From boxing crabs that wield poisonous anemones as weapons to shrimp that scour the mouths of electric eels, here are seven of the most radical symbiotic relationships from the shallowest to the deepest waters of our world.

Watercone
Watercone is a polycarbonate cone with the capacity to purify up to 1.5 liters of water a day with just a little solar energy.
All users have to do to create drinkable water is pour dirty or salt water into the cone’s black base, place the cone atop it in the sun. As the water evaporates upwards it condenses on the cone’s inner wall and tricles down into a seperate trough. To access the clean water simply lift the cone and pour.
