Bites Of Passage

From The National:

In the past few decades, the Asian tiger mosquito has travelled from its natural home in Southeast Asia to the ends of the earth, becoming one of the world’s most invasive species. Tom Scocca reports from the frontlines of the battle to halt the winged invasion.

The picnic cooler, resting up against the back side of a row house in Trenton, New Jersey, was an artefact designed solely for the use of human beings. It had been invented to meet a particular and exclusive set of needs, unique to 21st-century Homo sapiens: to allow the transport of cold beverages to locales without refrigeration – and, once there, to allow those humans, while drinking, to free up their opposable thumbs by setting their beverages down in the wilderness without a spill. For this, humans needed more than a picnic cooler; they needed one whose lid was inset with four cup holders.

There’s No Place Like Home

From Newsweek:

Fewer Americans are relocating than at any time since 1962. That's good news for families, communities ... and even the environment.

On almost any night of the week, Churchill's Restaurant is hopping. The 10-year-old hot spot in Rockville Centre, Long Island, is packed with locals drinking beer and eating burgers, with some customers spilling over onto the street. "We have lots of regulars—people who are recognized when they come in," says co-owner Kevin Culhane. In fact, regulars make up more than 80 percent of the restaurant's customers. "People feel comfortable and safe here," Culhane says. "This is their place."

A World Redrawn When America Showed Up On A Map, It Was The Universe That Got Transformed

Image: Nicholas Copernicus (Getty Images)

From Boston.com:

NEARLY FIVE CENTURIES ago, the Polish astronomer Nicholas Copernicus went public with one of the most important arguments ever made in the history of ideas. The earth did not sit immobile at the center of the universe, he wrote. It revolved around the sun.

It was the mother of all paradigm shifts, dismantling a model of the universe that had been dogma since antiquity. When he published his theory, in “On the Revolutions of the Heavenly Spheres” (1543), Copernicus provided a wealth of data on the movements of celestial bodies in support of his case. But what’s often overlooked is that he began his argument from the ground up, by focusing not on the heavens but the earth. In particular, he began with a geographical revelation, prompted by something he had recently come across on a new map.

Bouncing Back: How We Deal With Bereavement

Bouncing back (Image: Michael Blann/Stone)

From New Scientist:

WHAT is the best way of coping with the death of a loved one? Why do some people grieve more intensely than others? Such questions are traditionally left to counsellors and self-help gurus, but George Bonanno, a clinical psychologist at Columbia University in New York, is on a mission to answer them empirically. He has done a good job, interviewing thousands of bereaved people over decades and monitoring how they get through their troubled times.

Yet Bonanno's bottom line - that people are often much more resilient than we're led to believe - is rather unremarkable. Studies of Londoners during the Blitz and New Yorkers after 9/11 showed that few people suffer serious reactions to traumatic events.

We remember the 20th century because we've all lived in some part of it (unless of course a 9 year older is reading this) and seen lots of video about it. The century was well covered by modern media. We know less of the 19th century and some of its major natural events are not widely known.

As compared to the 19th century the 20th century was pretty calm from the standpoint of big natural changes. What I'm going to do with this post: Imagine that the 21st century turns out to be like the 19th century in terms of the severity of climate, volcanic, and other natural events.

A novel navigation system under development at Microsoft aims to tweak users' visual memory with carefully chosen video clips of a route. Developed with researchers from the University of Konstanz in Germany, the software creates video using 360-degree panoramic images of the street that are strung together. Such images have already been gathered by several different mapping companies for many roads around the world. The navigation system, called Videomap, adjusts the speed of the video and the picture to highlight key areas along the route.

Biggest Obstacle To Global Climate Deal May Be How To Pay For It

China’s president, Hu Jintao, seated at center, at a United Nations climate debate last month. Todd Heisler/The New York Times

From The New York Times:

As world leaders struggle to hash out a new global climate deal by December, they face a hurdle perhaps more formidable than getting big polluters like the United States and China to reduce greenhouse gas emissions: how to pay for the new accord.

The price tag for a new climate agreement will be a staggering $100 billion a year by 2020, many economists estimate; some put the cost at closer to $1 trillion. That money is needed to help fast-developing countries like India and Brazil convert to costly but cleaner technologies as they industrialize, as well as to assist the poorest countries in coping with the consequences of climate change, like droughts and rising seas.

Sea Levels Rose Two Feet This Summer In U.S. East

High tides lash a Destin, Florida, pavilion—usually on dry land—ahead of tropical storm Claudette on August 17, 2009.

Remembering The Man Who Made Jet Fighters Possible

He Sparked Supersonic Flight With A Coke Bottle And File -- Wall Street Journal

Richard T. Whitcomb dreamed up techniques that made supersonic flight possible and innovations that endure on passenger jets today.

Mr. Whitcomb, who died Oct. 13 at age 88, solved a problem that had bedeviled aviation engineers, whose designs couldn't achieve supersonic flight even though they seemed to have enough power. Increased wind resistance at speeds approaching the speed of sound was the problem. Engineers took to calling it the "sound barrier."

Rocking On With Hot Rocks Geothermal Energy

From NOVA:

The world is getting hotter. This is because of the increasing concentration of greenhouse gases in the atmosphere, due mainly to our excessive burning of fossil fuels. We burn them for the energy that is needed increasingly in our daily life – to drive to school, cool ourselves on hot summer days, blow-dry our hair and listen to our music. The resulting greenhouse gases trap radiation from the sun, preventing it from escaping back into space, causing the planet’s temperature to rise. But not all of the planet’s heat comes from the Sun; some of it is within the Earth; and rather than causing global warming it could help to wean us off fossil fuels.

This heat, geothermal energy, lies in abundance beneath our feet. If the energy stored in hot rocks inside the Earth could be tapped and used instead of fossil fuels, it could help to reduce the threat of climate change.
