Parents Lie to Children Surprisingly Often
From Live Science:
Parents might say "honesty is the best policy," but when it comes to interacting with their own kids, mom and dad stretch the truth with the best of them, finds a new study.
From claiming the existence of magical creatures to odd consequences of kids' actions, parents often come up with creative tales to shape a child's behaviors and emotions.

Transonic Hulls, Inspired by Racing Yachts, Could Add Stealth To Navy SEALs' Boats
Transonic Hull: Graham MurdochFrom 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.

Instant Expert: Weapons Technology
The Northrop B2 American stealth bomber (Image: Alisdair Macdonald/Rex Features)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?

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 KazmierskiFrom 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.Read more ....

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.

ScienceDaily (Sep. 28, 2009) — Unusually high temperatures in the Arctic and heavy rains in the tropics likely drove a global increase in atmospheric methane in 2007 and 2008 after a decade of near-zero growth, according to a new study. Methane is the second most abundant greenhouse gas after carbon dioxide, albeit a distant second.
NOAA scientists and their colleagues analyzed measurements from 1983 to 2008 from air samples collected weekly at 46 surface locations around the world. Their findings will appear in the September 28 print edition of the American Geophysical Union’s Geophysical Research Letters and are available online now.

Espinel, who requires Senate confirmation, has a past in teaching and government. Most recently, she was a visiting scholar at the George Mason University School of Law, where she taught intellectual property and international trade. The White House said she was an intellectual property adviser to the staff of the Senate Judiciary Committee, Senate Finance Committee, House Judiciary Committee and House Ways and Means Committee. Espinel, in 2005, served as the nation’s top trade negotiator for intellectual property at the Office of the U.S. Trade Representative.

Their discovery, detailed this week in the advance online issue of the journal Nature Photonics, follows the team’s demonstration last summer of an integrated circuit—an assembly of transistors that is the building block for all electronic devices—capable of working at 1.5 degrees Kelvin above absolute zero. That temperature, equivalent to minus 457 degrees Fahrenheit, is not only less than the average temperature of deep space, but achievable only in special research laboratories.

How To Truck 66 200,000-Pound Antennas To 16,000 Feet
From Wired Science:
After a 17-mile trek up to a plateau in the Chilean Andes, scientists installed the first of 66 giant antennae on the European Southern Observatory’s Atacama Large Millimeter/submillimeter Array (ALMA) telescope this week.
The antenna, which weighs about 100 tons and measures 40 feet in diameter, was carried to its operations site at 16,400 feet by a massive, custom-built transporter. Eventually, the antenna will be linked with dozens of others to form a single, enormous telescope. Scientists hope the extremely dry air on the Chajnantor Plateau will help ALMA study some of the coldest and most distant objects in the observable universe.
