on September 22 last year, Professor Robert Fuller
of the University of North Georgia spent four months paddling down the Chattahoochee River system, from the Chattahoochee's headwaters in northern Georgia down through the Apalachicola into the Gulf of Mexico, studying water quality
along the way. Then he paddled 200 miles through the Gulf, turned at the mouth of the Mobile River, and paddled another 750 miles upstream
on the Mobile, Alabama, Coosa, and Etowah Rivers all the way back
to northern Georgia—a total of just over 1,500 miles of solo paddling in his Kruger Sea Wind
. Along the way, he kept a blog
, "ate a lot of Beanie Weenies"
, and faced difficulties including cold, hunger, injuries, and river obstructions. Incidentally, he did all this while living with leukemia

Last fall, the Canadian Space Agency asked students to design a simple science experiment that could be performed in space, using items already available aboard the International Space Station. Today, Commander Chris Hadfield
conducted the winner for its designers: two tenth grade students, Kendra Lemke and Meredith Faulkner, in a live feed to their school in Fall River, Nova Scotia. And now, we finally have an answer to the age-old question, What Happens When You Wring Out A Washcloth In Space? [more inside]

NASA May Have Discovered Flowing Water on Mars Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars' southern hemisphere.

"We have water
," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA
. "We've seen evidence for this water ice before in observations by the Mars Odyssey orbiter and in disappearing chunks observed by Phoenix last month
, but this is the first time Martian water has been touched and tasted."

If you were doing research in the 60s, You might've heard of Polywater,
A form of water that exhibited wide variety of interesting characteristics and existed under identical conditions to that of normal water. Eventually debunked, none the less is a fascinating story. Naturally one draws parallels to Vonnegut's ice nine, but did you know there actually is an ice nine?
In fact, there's twelve to sixteen types of ice
, depending on your opinion.
More recently, computer simulations have indicated water may structure itself into icosahedra
, which, incredibly, is the platonic solid (described over 2000 years ago!) representing the element water!
And if you don't know what an icosahedron is, I bet you've used one before
. One of the most ubiquitous, and arguably most important,
substances in our lives, our understanding of water
is far from complete.

The Hidden Messages in Water?
Masaru Emoto claims that water has the ability "to absorb, hold, and even retransmit human feelings and emotions. Using high-speed photography, he found that crystals formed in frozen water reveal changes when specific, concentrated thoughts are directed toward it. Music, visual images, words written on paper, and photographs also have an impact on the crystal structure." The theory may be suspect
, but the photos are beautiful

Grab your water-wings while you can, because I'm afraid I am the bearer of bad tidings. We only have a billion years of beach time left,
because our planet's ocean's are going to dry up completely. Fortunately, earth will be almost completely unlivable by then, so our descendents will already be dead. According to professor of meterology James Kastings, "My calculations are somewhat pessimistic and present a worst case scenario..."
