From City Journal:
Urban revival, globalization, and some world-class chefs have created one of the world’s great culinary scenes.
In a 1769 letter to the naturalist John Bartram, Benjamin Franklin observed that while lots of people like accounts of old buildings and monuments, “I confess that if I could find in any Italian travels a receipt for making Parmesan cheese, it would give me more satisfaction than a transcript of any inscription from any old stone whatsoever.”

Five Ways To Teach Your Old Phone New Tricks
From The Christian Science Monitor:
This summer was a big season for smart-phone lovers. Apple unveiled a new iPhone with built-in video camera, compass, and online movie rental store. Palm released a worthy rival, the Pre, which lets busy multitaskers flip between e-mail, spreadsheets, and, of course, phone calls. And several touch-screen and next-gen smart phones are on the way.
That’s great news for gadget geeks ready to spend $90 a month (or more) on their cellphones. But what about the rest of us? Even simple mobile phones are capable of a lot these days, thanks to text messaging and a slew of services designed for the average phone. Here are a few tricks to get your plain ol’ cellphone acting like a smart phone.

Tyrannosaurs Flying F-14s!
The cover of this issue of Galaxy features an unusual space launch concept, but an article inside had more realistic and interesting insights.
From The Space Review:
The comic strip Calvin & Hobbes once ran a classic on a Sunday in 1995. Calvin and his tiger buddy are playing with toy dinosaurs and F-14 Tomcat fighter planes when Calvin concludes that the only thing cooler than tyrannosaurs and F-14s… is tyrannosaurs flying F-14s.
This is a scene that has been repeated throughout the history of human spaceflight, when somebody has come up with some concept for a rocket, spacecraft, whatever, that they decide can be made infinitely cooler by combining it with another concept for a rocket, spacecraft, whatever. Want to explore the icy moons of Jupiter? Let’s combine the most powerful ion engines ever built and the largest space nuclear reactor ever built and the largest rocket ever built. That would be cool. (It will also cost twenty-three billion dollars and never be built.)

Oddball Stars Explained: New Observations Solve Longstanding Mystery Of Tipped Stars
This artist's conception of the double-star system DI Herculis illustrates the key findings from the new research. Spectroscopic observations showed that the two stars are both tipped over almost horizontally, relative to the plane of their orbits around each other. Because they are rotating rapidly which creates equatorial bulges, the tidal interactions between the two slows down a regular variation in the plane of the orbits, called precession -- a slowing that had been a mystery for three decades.

From Science Daily:
ScienceDaily (Sep. 18, 2009) — A pair of unusual stars known as DI Herculis has confounded astronomers for three decades, but new observations by MIT researchers and their colleagues have provided data that they say solve the mystery once and for all.
It has long been clear that there was something odd going on in this double-star system, but it wasn't clear just what that was. The precession of the orbits of the two stars around each other — that is, the way the plane of those orbits change their tilt over time, like the wobbling of a top as it winds down — seems to take place four times more slowly than established theory says it should. The anomaly is so unexpected that at one point it was seen as possible evidence against Einstein's long-accepted theory of relativity.

Plugged-In Age Feeds a Hunger for Electricity
From The New York Times:
With two laptop-loving children and a Jack Russell terrier hemmed in by an electric fence, Peter Troast figured his household used a lot of power. Just how much power did not really hit him until the night the family turned off the overhead lights at their home in Maine and began hunting gadgets that glowed in the dark.
“It was amazing to see all these lights blinking,” Mr. Troast said.
As goes the Troast household, so goes the planet.
Electricity use from power-hungry gadgets is rising fast all over the world. The fancy new flat-panel televisions everyone has been buying in recent years have turned out to be bigger power hogs than some refrigerators.

How Broadband Is Changing Africa
From The BBC:
Fast broadband will transform Africa, and the rest of the world will change too, says Bill Thompson.
Norman Borlaug, whose work in Mexico and India led to the 'green revolution' in agricultural production, died last week and was widely commemorated for his important work.
While the introduction of new crops and the use of irrigation, fertilisers and pesticides certainly enabled us to feed millions of people, the crops were delivered at a price, and we should not forget that Borlaug's green revolution, like every revolution, had a negative as well as a positive side.

Warming Arctic 'Halts Migration'
From The BBC:
Milder winters in the Arctic region have led to fewer Pacific brants, a species of sea goose, migrating southwards, say researchers.
A study by the US Geological Survey (USGS) found that as many as 30% of the birds were overwintering in Alaska rather than migrating to Mexico.
Until recently, more than 90% of the species were estimated to head south.
Writing in the journal Arctic, the team said the shift coincides with warming in the North Pacific and Bering Sea.

VW Redefines ‘Car’ With A 170-MPG Diesel Hybrid
From Autopia:
Volkswagen is redefining the automobile with the L1, a bullet-shaped diesel hybrid that weighs less than 900 pounds, gets an amazing 170 mpg and might see production within four years.
The L1 concept car unveiled at the Frankfurt auto show pushes the boundaries of vehicle design and draws more inspiration from gliders than conventional automobiles. The only question the company’s engineers asked when designing the L1 was, “How would a car have to look and be built to consume as little energy as possible.” Their answer was small, light and extremely aerodynamic. Those guidelines led to a car that requires just 1.38 liters of diesel fuel to go 100 kilometers.

Chinese Climate Wisdom
From Watts Up With That?:
The Chinese civilization has existed survived intact far longer than any other in human history, and they have records of that civilization that span 2-3 thousand years BC. They’ve seen more climate change than any other civilization.
The Guardian recently interviewed Xiao Ziniu, the director general of the Beijing Climate Center.
Excerpts:
A 2C rise in global temperatures will not necessarily result in the calamity predicted by the Intergovernmental Panel on Climate Change (IPCC), China’s most senior climatologist has told the Guardian.

Pentagon Wants ‘Space Junk’ Cleaned Up
From The Danger Room:
The orbit around Earth is a very messy place and the Pentagon’s far-out research arm wants to do something about it. The Defense Advanced Research Projects Agency put out a notice yesterday requesting information on possible solutions to the infamous space debris problem.
“Since the advent of the space-age over five decades ago, more than thirty-five thousand man-made objects have been cataloged by the U.S. Space Surveillance Network,” the agency notes. “Nearly twenty-thousand of those objects remain in orbit today, ninety-four percent of which are non-functioning orbital debris.”

From The Telegraph:
Fake video footage can persuade almost half of viewers to accuse people of crimes they have not committed, new research suggests.
The study found that exposure to fabricated footage can "dramatically alter" individuals' version of events, even convincing them to testify as an eyewitness to an event that never happened.
The study, by Warwick University, found that almost 50 per cent of people shown false footage of an event they witnessed first hand were prepared to believe the video version rather than what they actually saw.

Solar Cycle Driven By More Than Sunspots; Sun Also Bombards Earth With High-speed Streams Of Wind
When the solar cycle was at a minimum level in 1996, the Sun sprayed Earth with relatively few, weak high-speed streams containing turbulent magnetic fields (left). In contrast, the Sun bombarded Earth with stronger and longer-lasting streams last year (right) even though the solar cycle was again at a minimum level. The streams affected Earth's outer radiation belt, posing a threat to earth-orbiting satellites, and triggered space weather disturbances, lighting up auroras in the sky at higher latitudes.
From Science Daily:
ScienceDaily (Sep. 18, 2009) — Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun's impact on Earth over the course of the 11-year solar cycle. The study, led by scientists at the High Altitude Observatory of the National Center for Atmospheric Research (NCAR) and the University of Michigan, finds that Earth was bombarded last year with high levels of solar energy at a time when the Sun was in an unusually quiet phase and sunspots had virtually disappeared.

Sea Stars Grow Faster As Water Warms
From Live Science:
Climate change will deal clams, mussels, and other marine bivalves a double whammy. Biologists already expect them to have trouble making their shells because elevated carbon dioxide (CO2) levels will acidify seawater. Now it seems they’ll also have to contend with brawnier predatory starfish.
Bivalves are the preferred prey of the purple ocher sea star (Pisaster ochraceus), a familiar denizen of the intertidal zone along the Canadian and American west coast.

High-Speed Video of Locusts Could Help Make Better Flying Robots
From Wired Science:
A new study may inspire aeronautical engineers to be more flexible with their designs. That’s because the bends and twists in locusts’ flexible, flapping wings power the insects’ extraordinary long-distance flights, a Sept. 18 Science paper reveals.
Even though researchers have been studying how insects and other creatures fly for a long time, “we still don’t completely understand the aerodynamics and architectures of wings,” comments Tom Daniel of the University of Washington in Seattle, who was not involved in the new study. The new work, Daniel says, uncovers the flight signatures of flapping, flexible wings.
