Transonic Hulls, Inspired by Racing Yachts, Could Add Stealth To Navy SEALs' Boats

Transonic Hull: Graham Murdoch

From Popular Science:

A knife-like boat design provides a covert, fuel-efficient ride.

An undercover team of Navy SEALs isn’t worth much if their transport boat’s wake betrays their approach. Nor does it help if they come ashore with back pain and possible organ damage from the boat’s constant bouncing. A sleek new hull design could help troops slip through waves undetected and unscathed, while also setting a new standard for efficient nautical design.

From New Scientist:

Violence and conflict have been a feature of human life throughout history. Starting with simple weapons, people have developed ever more advanced methods to kill one another. Technology has dominated warfare since the early 1900s, and an astounding 190 million people may have been killed during the 25 biggest conflicts of the 20th century.

Today guided weapons, like "smart" bombs dropped by stealth bombers, coupled with space-based sensors and precision satellite navigation, provide decisive advantages in conventional warfare. In this high-spending game, less capable opponents are soon reduced to guerrilla tactics, and human cost of war remains high.

Secret Service Investigating Facebook Poll On Obama

From CNN:

(CNN) -- The social networking site Facebook on Monday pulled a third-party application that allows users to create polls after a site member built a poll asking if President Obama should be killed.

The U.S. Secret Service, the agency assigned to protect the president, has launched an investigation, agency spokesman James Mackin said.

"As is usually the case, our vigilant users reported it to us first," Facebook spokesman Barry Schnitt told CNN. "The USSS [Secret Service] sent us an e-mail late this morning PDT asking us to take it down. At that point, it had already been removed, and we let them know."

A Life Of Its Own: Where Will Synthetic Biology Lead Us?

Image: If the science truly succeeds, it will make it possible to supplant the world created by Darwinian evolution with one created by us.

From The New Yorker:

The first time Jay Keasling remembers hearing the word “artemisinin,” about a decade ago, he had no idea what it meant. “Not a clue,” Keasling, a professor of biochemical engineering at the University of California at Berkeley, recalled. Although artemisinin has become the world’s most important malaria medicine, Keasling wasn’t an expert on infectious diseases. But he happened to be in the process of creating a new discipline, synthetic biology, which—by combining elements of engineering, chemistry, computer science, and molecular biology—seeks to assemble the biological tools necessary to redesign the living world.

I Switched From Firefox To Internet Explorer─And Lived To Tell!

From Newsweek:

I am a loyal Firefox user. I love the tabs, the extensions, the customization. It’s fast and free and, because it’s an open-source project organized by a nonprofit in Silicon Valley, it gives me a warm, fuzzy, volunteering-at-the-soup-kitchen kind of feeling. I love watching its market share grow, from 15 percent in 2007 to 23 percent today. Each uptick in the chart is like a poke in the red, gleaming, robotic eye of our technological overlord, Microsoft, and its crusty workhorse, Internet Explorer.

But recently I was issued a challenge by this blog: forsake Firefox for a week and entrust my digital life to Internet Explorer 8. I expected a cataclysm of Katrina-like proportions. Frozen screens. Garbled Web pages. Cascading popup boxes. Molasses-like speed. With great trepidation I accepted, and tremblingly clicked online.

But you know what? It was ... fine.

Does Falling in Love Make Us More Creative?

Adam Kazmierski

From Scientific American:

A new study demonstrates that thinking about love--but not about sex--causes us to think more "globally," making it easier to come up with new ideas.

Love has inspired countless works of art, from immortal plays such as Romeo and Juliet, to architectural masterpieces such as the Taj Mahal, to classic pop songs, like Queen's “Love of My Life”. This raises the obvious question: why is love such a stimulating emotion? Why does the act of falling in love – or at least thinking about love – lead to such a spur of creative productivity?

Slime-Dispensing Hulls Could Boost Fuel Efficiency For Ships

Slick Hull A fine sheen of slime could someday cover Navy vessel hulls such as this, and cut fuel consumption to boot. U.S. Navy

From Popular Science:

A DOD-backed project would give ships a regenerating slime layer to help shed unwanted marine life.

Slime ships ahoy! A vessel that oozes a continual slick layer of slime from its hull could shed barnacles and other marine life forms, and possibly cut its fuel consumption by up to 20 percent.

Such a novel idea tackles the problem of removing marine plants, barnacles and tube worms from ship hulls every year, lest the buildup cut into both speed and fuel efficiency. The fuel savings in particular may look especially tempting for the U.S. Department of Defense, which has backed the project and previously invested in hull-cleaning bots.

Are Recessions Good For Our Health?

Opportunity in Crisis? Although the Great Depression made have had a severe impact on the American economy, the crisis was actually good for U.S. health, according to a new study. The findings offer a silver lining for today's financial crisis. StockPhoto

From Discovery News:

Sept. 28, 2009 -- The name seems to say it all. The Great Depression was bad all around, wasn't it? Maybe not.

New findings show that the Great Depression was actually good for U.S. health. Annual death rates declined during years of downturn and increased in years of expansion.

The findings could offer a silver lining to today's financial crisis.

The results reinforce earlier research showing recessions reduce mortality, but researchers didn't know whether the effect would hold through a full blown economic meltdown like the Great Depression.

From Cosmos:

PARIS: Children who are the most popular and powerful at school also enjoy better health in adult life compared to counterparts at the bottom end of the pecking order, say Swedish scientists.

The long-term study covers 14,000 children born in 1953, who were questioned in 1966 when they were 12 or 13 years old and whose health was tracked up to 2003.

The children's place in the social hierarchy was determined by asking them who they most preferred to work with at school.

To assess their health in later life, the study delved into a national databank for hospital admissions.

Giant Fish 'Verges On Extinction'

From The BBC:

One of the world's largest freshwater fish is on the verge of going extinct.

A three-year quest to find the giant Chinese paddlefish in the Yangtze river failed to sight or catch a single individual.

That means that the fish, which can grow up to 7m long, has not been seen alive for at least six years.

There remains a chance that some escaped the survey and survive, say experts, but without action, the future of the species is bleak.

From Technology Review:

An energy-efficient silicon device compresses light to make ultrafast signals.

Researchers at Cornell University have developed a simple silicon device for speeding up optical data. The device incorporates a silicon chip called a "time lens," lengths of optical fiber, and a laser. It splits up a data stream encoded at 10 gigabits per second, puts it back together, and outputs the same data at 270 gigabits per second. Speeding up optical data transmission usually requires a lot of energy and bulky, expensive optics. The new system is energy efficient and is integrated on a compact silicon chip. It could be used to move vast quantities of data at fast speeds over the Internet or on optical chips inside computers.
