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 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.

From Science Daily:

ScienceDaily (Sep. 28, 2009) — Physicists at UC San Diego have successfully created speedy integrated circuits with particles called “excitons” that operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality.

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.

Modern parents, teenagers, and executives are all masters of multitasking, but people who lived 70,000 years ago may have shared that talent. Stone blades found in Sibudu Cave, near South Africa’s Indian Ocean coast, bear traces of compound adhesives that once joined them to wooden hafts to make spears or arrows.

Our distant ancestors discovered that mixtures of plant gum and red ocher or fat, heated carefully over a fire, made the superglue of their day, say Lyn Wadley and two colleagues at the University of the Witwatersrand in Johannesburg. So how is that evidence of multitasking?

US Life Expectancy Lags Due To Cigarettes

From Future Pundit:

In political debates over health care the fact that the United States lags many other industrialized countries in average life expectancy is sometimes blamed on how health care is funded in the US. But John Tierney of the New York Times reports that once the lifestyles of Americans are adjusted for America's health care system comes out looking pretty good in terms of its effects on longevity.

But a prominent researcher, Samuel H. Preston, has taken a closer look at the growing body of international data, and he finds no evidence that America’s health care system is to blame for the longevity gap between it and other industrialized countries. In fact, he concludes, the American system in many ways provides superior treatment even when uninsured Americans are included in the analysis.

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.

You're known as a techno-optimist. Why have you got such faith in technology's power to save the environment?

I regard myself as neither an optimist nor a pessimist. But I do think that humanity is ingenious and enterprising. Throughout the ages people have doubted that their descendants could exist, with improving health and longevity, in the numbers and densities we do now. In the 19th century it was common to reason that horse manure or chimney smoke would bury or choke cities. Yet air quality in New York City and water quality in New York harbour are better than when I or my mother was a child. Over time people find, invent and spread solutions for many environmental problems.

Population: Enough Of Us Now -- A Commentary

Cities contain many people, but it is not just numbers that put strain on resources, it is the way we consume also (Image: Duncan McKenzie/Getty)

From New Scientist:

GLOBAL population growth has slowed significantly, but it hasn't stopped. By 2050 there may be about 35 per cent more people on Earth than there are today. We are already seeing increasing shortages of food, water and other resources and growing numbers of hungry people.

Yet to embark on any discussion about limiting our numbers is to enter sensitive and controversial territory. Perhaps this is not surprising, as in the 1960s, when population growth became an issue of widespread concern, the discussions often had a racist undertone, in which the "well-off" focused on the exploding populations of "underdeveloped nations".
