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.

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.

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.

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.

From Scientific American:

The information age began with the realization that machines could emulate the power of minds

In the standard story, the computer’s evolution has been brisk and short. It starts with the giant machines warehoused in World War II–era laboratories. Microchips shrink them onto desktops, Moore’s Law predicts how powerful they will become, and Microsoft capitalizes on the software. Eventually small, inexpensive devices appear that can trade stocks and beam video around the world. That is one way to approach the history of computing—the history of solid-state electronics in the past 60 years.

Most pilots would head away from a thermonuclear explosion.

He wasn’t supposed to do it, but on May 15, 1948, Lieutenant Colonel Paul H. Fackler, commanding officer of the U.S. Air Force 514th Reconnaissance Squadron Weather, flew his airplane into the seething mushroom cloud of an atomic bomb detonation.
As part of Zebra, the final shot of America’s second series of atomic tests at Enewetak atoll in the Pacific, Fackler had the job of tracking the atomic cloud from at least 10 miles away, hoping that special filters attached to the airplane would catch samples of the radioactive debris. But as he pulled away from the enormous roiling cloud in a climbing turn to the left, Fackler suddenly found his weather reconnaissance Boeing WB-29 inside a small finger-like projection of the main cloud.

LIKE moths about a flame, thousands of tiny satellite galaxies flutter about our Milky Way. For astronomers this is a dream scenario, fitting perfectly with the established models of how our galaxy's cosmic neighbourhood should be. Unfortunately, it's a dream in more ways than one and the reality could hardly be more different.

As far as we can tell, barely 25 straggly satellites loiter forlornly around the outskirts of the Milky Way. "We see only about 1 per cent of the predicted number of satellite galaxies," says Pavel Kroupa of the University of Bonn in Germany. "It is the cleanest case in which we can see there is something badly wrong with our standard picture of the origin of galaxies."

Cutting The Cord: America Loses Its Landlines

From The Economist:

Ever greater numbers of Americans are disconnecting their home telephones, with momentous consequences.

MUCH has been made of the precipitous decline of America’s newspapers. According to one much-cited calculation, the country’s last printed newspaper will land on a doorstep sometime in the first quarter of 2043. That is a positively healthy outlook, however, compared with another staple of American life: the home telephone. Telecoms operators are seeing customers abandon landlines at a rate of 700,000 per month. Some analysts now estimate that 25% of households in America rely entirely on mobile phones (or cellphones, as Americans call them)—a share that could double within the next three years. If the decline of the landline continues at its current rate, the last cord will be cut sometime in 2025.
