Tuning In Space Noise For Sounds Of Life
|7:29:28 PM, Monday, February 21, 2011|
“Earlier this month, NASA's Kepler Mission announced it had found 54 planets orbiting stars in so-called "habitable zones" in our galaxy, where the climate could be suitable for liquid water.
After the planets were found, NASA alerted the SETI Institute (Search for Extraterrestrial Intelligence) of their locations. The institute's scientists started listening to those planets, and while they haven't heard any intelligent life yet, there's plenty of other noise to be heard in space.
Sounds You Can't Hear
SETI chief Jill Tarter says the Institute is not listening for the kind of sound you hear with your ears.
"What we're doing is using sensors that are sensitive to electromagnetic radiation," she says.
Electromagnetic radiation — like the energy in your microwave or from your reading lamp — is just another name for energy that travels in wave form. Radio signals are also a form of wave energy. So when SETI "listens" to the cosmos, the institute is actually receiving electromagnetic radiation.
"And then, just the way your radio does, that energy can be used to make audible sound," Tarter says…”

Darpa’s New Recruits: You, Your Grandpa and Your Dog
|4:06:17 AM, Monday, February 21, 2011|
“Perhaps you think you’re too fat, too old or too busy to help fight America’s wars. Perhaps you’re not even a human being. The Pentagon’s way-out research arm begs to differ. The military can use your talents — whether you stand or four legs or on two.
Right now, only 1 percent or so of America’s population contributes to the country’s defense (and offense). In its new budget, Darpa announces a $25 million effort to build tools that’ll rope in the other 99 percent. (Doesn’t exactly explain how. But think crowd-sourcing, plus a touch of machine learning to pair peeps up.) The program is called “Unconventional Warfighters,” and the idea is to tap three pools of potential contributors.
First, Darpa is looking to plug in “futurists, inventors, hobbyists and tinkerers who approach military problems from an unconventional perspective.” Then, the agency would like to call upon “military Veterans, including disabled Veterans, who have deep knowledge of the missions and the operational environment.” Lastly, Darpa wants those veterans’ pets.
“Animals are another class of potential contributors,” the agency explains in its budget. “This is not a new idea, as animals possessing special abilities such as dogs and dolphins have been used before to perform military tasks such as mine detection. The new aspect to be examined under Unconventional Warfighters is the potential for creating new sensor, processing, communication and actuator systems specially adapted to enable animals to execute tasks beyond their natural capabilities.”
No, I’m not sure what that means, either.
But get past the giggle factor, and there’s a strong core to Darpa’s program. There are hundreds of thousands, maybe millions, of people in this country who are willing to offers their skills and their time to help respond to a disaster or a political crisis — think the Haiti earthquake, or the Middle Eastern revolt. It stands to reason there are a good number of folks who are willing to contribute to national security, too. But the American system doesn’t have a good way of allowing those people to plug in, unless they’re able to join the ranks of the uniformed military or the contractor corps. “Unconventional Warfighters” is a possible way around that…”

A Pro-Nazi U.S. Army Unit in WWII
|5:13:13 PM, Sunday, February 20, 2011|
“Yep. Gather round, little grasshoppers, and I will tell the strange tale.
I know it sounds like the reverse of a Quentin Taratino movie, but it is true: During World War II, the Army intentionally formed a unit chockablock withfascisti and their suspected sympathizers. What a sensible idea -- much better than kicking them out into society and losing track of them.
This is all discussed in the new issue of Army Lawyer, where Fred "Three Sticks" Borch has a fascinatingarticle about PFC Dale Maple, a brilliant young man who was born in San Diego in 1920 and who graduated from Harvard with honors but then, because he was bad, was found guilty of treason and sentenced to be hanged by the neck until dead.
Young Maple spoke many languages. But his favorite, alas, was German. At Harvard he got kicked out of ROTC for being vocally pro-German when that just wasn't cool, according to a separate article on him that I just read. Stymied in his hopes to do post-graduate work in Berlin, which was busy with other things at the time, he enlisted in the Army in 1942. The Army had just the place for him: the 620th Engineer General Service Company, which despite its innocuous name was actually a holding unit for about 200 GIs of suspect loyalty, many of them German-born. The unit, which was not given weapons, was located in Camp Hale, Colorado, which is far from any port, but happened to next to an detachment of German PoWs on a work party.
And thereby hangs this tale. In February 1944 Private Maple decided it would be a good idea to help some hard-boiled eggs from the Afrika Korps escape to Mexico. Southward he drove them though New Mexico-a lovely drive, I've done much of it. Just across the international border, Mexican authorities caught them all and tossed them back. (Is there a derogatory term for people who illegally cross from the U.S. into Mexico, besides "stupid gringos"?) Maple was tried and found guilty and secretly sentenced to death. President Roosevelt clemently commuted his sentence to life, and he was released in 1951. Maple's claim to notoriety is that he was the first American-born GI ever found to have committed treason.
As best as I can tell from an internet search, Maple then moved back to San Diego and, like a Tom Waits song, went into the insurance business. He apparently died 10 years ago.”

The Diamond Mine Vehicle Graveyard of Namibia
|3:16:28 PM, Sunday, February 20, 2011|
"Oranjemund, Namibia. It seems to be the largest diamond mine vehicle graveyard, and yet there are barely any pictures of it. Satellite photos of the area could let you guess how big it is. The mine owned by De Beers is reputed to have the largest private earthmoving fleet in the world.
From the texts I have found here and there, my understanding is that that people are not allowed to visit those the area for safety reasons, hence the lack of available photos."
World's First Anti-Laser Built
|11:34:16 PM, Saturday, February 19, 2011|
“More than 50 years after the invention of the laser, scientists at Yale University have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discovery could pave the way for a number of novel technologies with applications in everything from optical computing to radiology.
Conventional lasers, which were first invented in 1960, use a so-called "gain medium," usually a semiconductor like gallium arsenide, to produce a focused beam of coherent light -- light waves with the same frequency and amplitude that are in step with one another.
Last summer, Yale physicist A. Douglas Stone and his team published a study explaining the theory behind an anti-laser, demonstrating that such a device could be built using silicon, the most common semiconductor material. But it wasn't until now, after joining forces with the experimental group of his colleague Hui Cao, that the team actually built a functioning anti-laser, which they call a coherent perfect absorber (CPA).
The team, whose results appear in the Feb. 18 issue of the journal Science, focused two laser beams with a specific frequency into a cavity containing a silicon wafer that acted as a "loss medium." The wafer aligned the light waves in such a way that they became perfectly trapped, bouncing back and forth indefinitely until they were eventually absorbed and transformed into heat…”
Astronomy Picture of the Day: Hidden Treasures of M78
|2:41:03 PM, Saturday, February 19, 2011|
M78 isn't really hiding in planet Earth's night sky. About 1,600 light-years away and nestled in the nebula rich constellation Orion, the large, bright, reflection nebula is well-known to telescopic skygazers. But this gorgeous image of M78 was selected as the winner of the Hidden Treasures 2010 astrophotography competition. Held by the European Southern Observatory (ESO), the competition challenged amateur astronomers to process data from ESO's astronomical archive in search of cosmic gems. The winning entry shows off amazing details within bluish M78 (center) embraced in dark, dusty clouds, along with a smaller reflection nebula in the region, NGC 2071 (top). Yellowish and even more compact, the recently discovered, variable McNeil's Nebula is prominent in the scene below and right of center. Based on data from ESO's WFI camera and 2.2 meter telescope at La Silla, Chile, this image spans just over 0.5 degrees on the sky. That corresponds to 15 light-years at the estimated distance of M78.
China and Colombia Announce 'Alternative Panama Canal'
|2:36:07 PM, Saturday, February 19, 2011|
“Colombia has announced it is negotiating with China to build an alternative to the Panama Canal.
The proposed transport route is intended to promote the flow of goods between Asia and Latin America.
The plan is to create a "dry canal" where the Pacific port of Buenaventura would be linked by rail, across Colombia, to the Atlantic Coast.
Trade between Colombia and China has increased from $10m in 1980 to more than $5bn last year.
The announcement came from the Colombian president, Juan Manuel Santos, who told the Financial Times that the project was "a real proposal... and it is quite advanced".
China has been increasing its involvement across Latin America to feed a growing need for raw materials and commodities.
According to BBC Bogota correspondent Jeremy McDermott, President Santos has departed from the emphasis on security of his predecessor Alvaro Uribe.
Mr Uribe's Democratic Security Policy, backed by US military aid, is credited with halving the numbers of Marxist rebels and pushing them into the more remote jungles and mountains.
Mr Santos is concentrating on what he calls "democratic prosperity", our correspondent says.
He hopes that economic development will address some of the root issues of the 46-year civil conflict, such as poverty and the lack of opportunities, which have pushed people into being rebels or into the lucrative drug trade, our correspondent says…”
