FUTURE FARMS: High-Rise, Beach Pod, And Pyramid Pictures
From National Geographic:
The Pyramid Farm, designed by vertical farming guru Dickson Despommier at New York's Columbia University and Eric Ellingsen of the Illinois Institute of Technology, is one way to address the needs of a swelling population on a planet with finite farmland.
Design teams around the world have been rolling out concepts for futuristic skyscrapers that house farms instead of--or in addition to--people as a means of feeding city dwellers with locally-grown crops.

The Origin Of Computing
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.

Bilinguals Are Unable To 'Turn Off' A Language Completely, Study Shows
From Science Daily:
ScienceDaily (Aug. 19, 2009) — With a vast majority of the world speaking more than one language, it is no wonder that psychologists are interested in its effect on cognitive functioning. For instance, how does the human brain switch between languages? Are we able to seamlessly activate one language and disregard knowledge of other languages completely?
According to a recent study published in Psychological Science, a journal of the Association for Psychological Science, it appears humans are not actually capable of "turning off" another language entirely. Psychologists Eva Van Assche, Wouter Duyck, Robert Hartsuiker and Kevin Diependaele from Ghent University found that knowledge of a second language actually has a continuous impact on native-language reading.

Breakthrough Makes LED Lights More Versatile
From Live Science:
LEDs have started to blink on all over the place in recent years, from car taillights to roadside billboards. But design and manufacturing drawbacks have limited the ways in which the energy-efficient lights can be used.
A new study, detailed in the Aug. 21 issue of the journal Science, tackles these limitations by combining the best of two worlds of LEDs to make ultrathin, ultrasmall and flexible light-emitting diodes that may one day be used to create everything from laptop screens to biomedical imaging devices.

Into The Mushroom Cloud

From Air & Space Smithsonian:
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.

Mystery Of The Missing Mini-Galaxies
From New Scientist:
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."

We DO like Mondays... But We Really Don't Like The Mid-Week Misery Of Wednesday
From The Daily Mail:
With work beckoning after a relaxing weekend, Monday has traditionally been thought of as the most miserable day of the week.
But with memories of the days off still fresh, Mondays are actually the second happiest day of the week according to researchers.
Peter Dodds and Christopher Danforth, applied mathematicians at the University of Vermont, believe they have found a way to measure collective happiness and found we are at our lowest on Wednesdays.

From Space Flight Now:
Managers in charge of an October flight test of NASA's new Ares rocket defended the merits of the $350 million launch Sunday, telling reporters the demo provides valuable experience for engineers, no matter what booster the agency uses to replace the retiring space shuttle.
"We have a very high confidence level that Ares 1-X is germane to NASA, period," said Bob Ess, the flight's mission manager. "No caveats."
The Ares 1-X vehicle, a 327-foot-tall rocket that nearly reaches the rafters of the mammoth Vehicle Assembly Building, is undergoing final checks before its scheduled Oct. 31 launch.

The Origin of Rubber Boots
ROASTING RUBBER: Amazonian Indians may have originated the rubber boot over a campfire. ISTOCKPHOTO/SKI88
From Scientific American:
Galoshes seem to have come from a little fire, Amazonian Indians' boredom and Charles Goodyear's luck.
Perhaps the Indians roasted them like s'mores—rotating them ever so slowly to make sure every side got just dark enough, but not so long that they caught on fire. Or maybe they went all out, expediting the process and blowing out any flames. Of course, for the art of hovering a rubber-coated foot over a fire, one's pain tolerance may have ultimately determined how long the process went on.

Can Microsoft's Bing, or Anyone, Challenge Google?
From Time Magazine:
Every year, the market-research firm Millward Brown conducts a survey to determine the economic worth of the world's brands — in other words, to put a dollar value on the many corporate logos that dominate our lives. Lately the firm's results have been stuck on repeat: Google has claimed the top spot for the past three years. The most recent report values Google's brand — those six happy letters that herald so many of our jaunts down the Web's rabbit hole — at more than $100 billion.

Tweeting No Longer For The Birds, But Not Just For Twitter, Either
Photo: U.S. trademark ruling says many other companies have filed requests to claim ownership of the word ‘tweet'.
From The Globe And Mail:
Tweeting used to be for the birds, but the term has taken on a whole new meaning with the explosion in popularity of Twitter, an online service that allows users to blog via 140-character “tweets.”
But efforts by Twitter to trademark the word “tweet” have suffered a major setback after U.S. officials said others might have beaten the microblogging pioneer to the punch.

How We Support Our False Beliefs
From Science Daily:
ScienceDaily (Aug. 23, 2009) — In a study published in the most recent issue of the journal Sociological Inquiry, sociologists from four major research institutions focus on one of the most curious aspects of the 2004 presidential election: the strength and resilience of the belief among many Americans that Saddam Hussein was linked to the terrorist attacks of 9/11.
Although this belief influenced the 2004 election, they claim it did not result from pro-Bush propaganda, but from an urgent need by many Americans to seek justification for a war already in progress.

Powerful Ideas: Beer Waste Makes Fuel
From Live Science:
After beer is made, the waste from breweries could help generate power, researchers now suggest.
One problem brewers face is what to do with the thousands of tons of grain left over at the end of the brewing process. In the past, they just sold the waste to farmers who either fed it to their animals or spread it on their fields as fertilizer. However, in Europe, given reductions in cattle breeding and stricter regulations on what waste is allowed on land, neither option is as easy anymore.

Will Antitrust Probe Keep Microsoft, Yahoo Apart?
From The Miami Herald/AP:
WASHINGTON -- Yahoo Inc. and Microsoft Corp. hope that by joining forces, they can tilt the balance of power in Internet search away from Google Inc. First, however, Yahoo and Microsoft have to convince regulators that their plan won't hurt online advertisers and consumers.
As the U.S. Justice Department reviews the proposed partnership, approval figures to hinge on this question: Will the online ad market be healthier if Google's dominance is challenged by a single, more muscular rival instead of two scrawnier foes?

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.

Northwest Fears That Invasive Mussels Are Headed Its Way
From McClatchy News:
WASHINGTON — Highly invasive mussels are lurking on the Northwest's doorstep, threatening to gum up the dams that produce the region's cheap electricity, clog drinking water and irrigation systems, jeopardize aquatic ecosystems and upset efforts to revive such endangered species as salmon.
Despite efforts to stop them, the arrival of zebra and quagga mussels may be inevitable.

Moonquake Mystery Deepens
From Earth Magazine:
Between 1969 and 1972, five Apollo missions installed seismic stations at their landing sites on the nearside of the moon. Because the moon was thought to be seismically dead, the instruments were left almost as an afterthought to detect meteor strikes. But from the time the stations were switched on until they were decommissioned in 1977, they recorded hundreds of internally generated moonquakes, some as strong as magnitude 5.5 on the Richter scale.
