Scientists Design Plant Filtration System That Lets You Drink Your Own SHOWER Water

From The Daily Mail:

Eco-thinkers have come up with an amazing new way to create drinking water - by putting plants in the bottom of a shower.

Designers Jun Yasumoto, Vincent Vandenbrouk, Olivier Pigasse, and Alban Le Henry came up with the concept when looking for new ways to recycle precious H2O.

After you have washed in the special eco-shower the water passes down into a series of physical filters and is treated by plants such as reeds and rushes growing around your feet.

From New Scientist:

NATURAL catastrophes such as asteroid impacts, massive volcanic eruptions or large-scale wildfires would have periodically plunged our planet into abnormal darkness. How did life survive without the sun's life-giving rays during such episodes? With a little help from organisms that can switch to another source of energy while they wait for sunlight to pierce the darkness once more.

3 New Farm Bots Programmed To Pick, Plant And Drive

From Popular Mechanics:

Intelligent, manned machines aren’t just for warplanes and border guards—they can be found on the farm too. Increasingly, agro-bots are taking laborious tasks out of the farmer’s helper’s hands, and saving time and money in the process. Here are three robotic farm servants who may right now be working in a field near you.

Agricultural robots are already among us: mowing grass, spraying pesticides and monitoring crops. For example, instead of regularly dousing an entire apple orchard with chemicals, towed sensors find diseases or parasites with infrared sensors and cameras, and spray only the affected trees. But could a robot wholly replace a migrant worker?

Why Sleep? Snoozing May Be Strategy To Increase Efficiency, Minimize Risk

New research concludes that sleep's primary function is to increase animals' efficiency and minimize their risk by regulating the duration and timing of their behavior. (Credit: iStockphoto/Justin Horrocks)

From Science Daily:

ScienceDaily (Aug. 23, 2009) — Bats, birds, box turtles, humans and many other animals share at least one thing in common: They sleep. Humans, in fact, spend roughly one-third of their lives asleep, but sleep researchers still don't know why.

According to the journal Science, the function of sleep is one of the 125 greatest unsolved mysteries in science. Theories range from brain "maintenance" — including memory consolidation and pruning — to reversing damage from oxidative stress suffered while awake, to promoting longevity. None of these theories are well established, and many are mutually exclusive.

From Live Science:

Morphing blades made of advanced composite materials that can rapidly change their shape depending on the wind could help lead to advanced wind turbines that perform better and last longer.

Wind energy is growing more and more popular worldwide. The United States is currently the world's largest generator of wind energy by total megawatts, and by 2030, the Department of Energy predicts that as much as one-fifth of the nation's power might come from wind. On a per capita basis, other nations are even further ahead of the United States — Denmark, for instance, already gets one-fifth of its power from the wind.

6 More Shuttle Launches Befiore The Fleet Is Retired

Countdown To Discovery Blast-Off -- The Telegraph

Only six more such flights by Nasa remain before its three shuttles are retired from service.

Nasa is counting down to the next journey to the International Space Station (ISS) by the space shuttle Discovery, which after a postponement early this morning is scheduled for another attempt in the small hours of tomorrow.

A crew of seven, including the ISS’s newest astronaut, Nicole Stott, looks 70 per cent certain to head out with 6.8 tonnes of cargo, including an exercise treadmill, with the chance of favourable weather dropping to 60 per cent on Thursday. The weather is the limiting factor.

From New Scientist:

In the struggle to free the Mars rover Spirit from a sand trap, NASA engineers are bringing out the reserve troops. A second, lighter duplicate rover slid into a sandbox for testing this week, delaying any attempt to free Spirit by as much as three weeks, to mid-September.

Spirit has been stuck in a sandpit for nearly four months. Since late June, engineers have been trying to determine the best moves to extricate it by driving a test rover around a sandbox at NASA's Jet Propulsion Laboratory (JPL) in California.

The Enduring Mystery of Saturn's Rings

From Space.com:

Saturn's rings have fascinated scientists ever since Italian astronomer Galileo Galilei first spotted them through one of his telescopes in the 17th century. But just how the icy rings came into being remains a mystery that has only deepened with each new scientific finding.

Astronomers now know that the planet hosts multiple rings that consist of roughly 35 trillion-trillion tons of ice, dust and rock. The Cassini spacecraft and its Voyager predecessors have also spotted changing ring patterns, partially formed ring arcs and even a moon spewing out icy particles to form a new ring. All of this suggests that the rings have constantly evolved over time.

From Science Daily:

ScienceDaily (Aug. 24, 2009) — New insight into how human cells reproduce, published by cancer researchers at Michigan State University and the Van Andel Research Institute in Grand Rapids, could help scientists move closer to finding an “off switch” for cancer.

Cancer cells divide uncontrollably and can move from one part of the body to another. They undergo dramatic shifts in shape when they do so, said Aaron DeWard, an MSU cell and molecular biology doctoral candidate who published his research recently in the Journal of Biological Chemistry. He’s trying to figure out how certain proteins trigger cell movement and division and how cancer hijacks the system to create genomic instability.

Freak Hurricane Wave Strikes Maine

This rare photo of a rogue wave was taken by first mate Philippe Lijour aboard the supertanker Esso Languedoc, during a storm off Durban in South Africa in 1980. The wave approached the ship from behind before breaking over the deck, but in this case caused only minor damage. The wave was between 16 and 33 feet (5-10 meters) tall.

From Live Science:

No matter how much warning officials give, some people flock to the shore to see waves from hurricanes. The ocean, however, is not always as predictable as people might like.

Though Hurricane Bill did not make a direct hit on the U.S. East Coast, its wave-making power was made clear Sunday when a surprisingly large wave, termed a "rogue wave" by the Portland Press Herald, struck Acadia National Park. A 7-year-old girl was killed, and three other people had to be pulled from the water.
