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.

Standing up for GM: Kurzweil believes that opposition to advances such as genetic modification harm humankind. GETTY IMAGES

From The Independent:

...or at least that's what Ray Kurzweil thinks. He has spent his life inventing machines that help people, from the blind to dyslexics. Now, he believes we're on the brink of a new age – the 'singularity' – when mind-boggling technology will allow us to email each other toast, run as fast as Usain Bolt (for 15 minutes) – and even live forever. Is there sense to his science – or is the man who reasons that one day he'll bring his dad back from the grave just a mad professor peddling a nightmare vision of the future?

From Science Daily:

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.

Obama Appoints Scholar As New Copyright Czar

From The Threat Level:

The “copyleft” and the “copyright” are both applauding the presidential appointment Friday of Victoria A. Espinel to become the nation’s first copyright czar.

Congress created the new czar position last year as part of intellectual property reform legislation.

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.
