Recycled Plastic Bridges Can Support Tanks

Heavy Artillery: U.S. Marines clean an M1A1 Abrams main battle tank at Marine Corps Air Ground Combat Center, Twentynine Palms, Calif. Bridges made from recycled plastic are not only about to support the weight of this tank, but also can provide a cost-effective alternative to steel and concrete construction. Lance Cpl. Kelsey J. Green/U.S. Marine Corps

From Discovery News:

The U.S. Army may soon be able to recycle today's trash to support tomorrow's soldiers. New bridges made from recycled detergent bottles and car bumpers are strong enough to hold up a 73-ton Abrams tank.

The recycled plastic bridge takes only a month to build, costs 25 percent less than an equivalent wooden bridge and requires no annual maintenance.

Rutgers University professor Tom Nosker began developing plastic bridges, lumber and railroads ties back in the 1980s.

Spying On A Stolen Laptop

From CNET:

Imagine your laptop gets stolen. Wouldn't it be great to remotely spy on the machine and get it back?

In the last year — solar panel prices dropped to $2.10 a watt from about $4.10 in Germany — and only about half the global manufacturing capacity is being used, said Steve O'Rouke, an analyst with Deutsche Bank.

"We've seen an awful lot of angst and difficulty," O'Rouke said. "You have to expect some companies to go out of business."

Deutsche Bank is forecasting a structural over-supply in the market until at least 2011.

Controversial Moon Origin Theory Rewrites History

Origin Story. A new study challenges the giant impact hypothesis, which suggested the moon formed from a cosmic collision. NASA

From Discovery:

Oct. 22, 2009 -- The moon may have been adopted by our planet instead of descended from it.

If a new twist on a decades-old theory is right, conditions in the early solar system suggest the moon formed inside Mercury's orbit and migrated out until it was roped into orbit around Earth.

The idea flies in the face of scientific consensus, known as the giant impact hypothesis, which holds that the moon formed from red-hot debris left over after a Mars-sized object collided with Earth around 4.5 billion years ago.

The promise of biofuels like ethanol is that they will someday help the world grow its way out of its addiction to oil. Nine billion gallons of corn ethanol were produced in the U.S. in 2008, while countries like Brazil have already widely replaced gasoline with ethanol from sugar cane and countless start-ups are working to bring cellulosic and other second-generation biofuels to market. The reasoning is that if we use greener biofuels in place of gasoline, it will significantly enhance our effort to reduce greenhouse-gas emissions.

Unraveling The Brain's Secrets: Humility Required

From Scientific American:

In early October, the Singularity Summit took place on Manhattan’s Upper East Side, a conference that highlighted the prospects for abolishing the ravages of aging and disease. So you’ll be able to live forever, unless you get hit by a truck.

Living forever is mainly about preserving brain function. That’s why the cryonicists—the ones who freeze themselves until some hypothetical medical miracle emerges to revive them—often just put the part above the neck into deep storage. The head in the cooler, it is assumed, retains the operating system and all of the applications software needed to resurrect the former self, even if it is ported to some new, cybernetic body. Less real estate and a lower electricity bill means a reduced rate at the cryo farm until you are brought back from the “legally dead.” In essence, bleacher seats for the Singularity.

Darwin Lives! Modern Humans Are Still Evolving

A. Green / Corbis

From Time Magazine:

Modern Homo sapiens is still evolving. Despite the long-held view that natural selection has ceased to affect humans because almost everybody now lives long enough to have children, a new study of a contemporary Massachusetts population offers evidence of evolution still in action.

A team of scientists led by Yale University evolutionary biologist Stephen Stearns suggests that if the natural selection of fitter traits is no longer driven by survival, perhaps it owes to differences in women's fertility. "Variations in reproductive success still exist among humans, and therefore some traits related to fertility continue to be shaped by natural selection," Stearns says. That is, women who have more children are more likely to pass on certain traits to their progeny.

Representing the songwriters, singers, actors, producers and other entertainers in Memphis and Nashville, she said the creative community does not want the federal government to interfere with how they are able to get content to consumers via the Internet.

"Net neutrality, as I see it, is the fairness doctrine for the Internet," she said. The creators "fully understand what the fairness doctrine would be when it applies to TV or radio. What they do not want is the federal government policing how they deploy their content over the Internet and they want the ISPs to manage their networks and deploy the content however they have agreed on with ISP.
