From The New Scientist:

SOME 16 million years ago, north became south in a matter of years. Such fast flips are impossible, according to models of the Earth's core, but this is now the second time that evidence has been found.

The magnetic poles swap every 300,000 years, a process that normally takes up to 5000 years. In 1995 an ancient lava flow with an unusual magnetic pattern was discovered in Oregon. It suggested that the field at the time was moving by 6 degrees a day - at least 10,000 times faster than usual. "Not many people believed it," says Scott Bogue of Occidental College in Los Angeles.

They Crawl, They Bite, They Baffle Scientists

THE ICK FACTOR The lab of Stephen A. Kells, a University of Minnesota entomologist. Bedbugs are not known to transmit disease. Allen Brisson-Smith for The New York Times

From The New York Times:

Don’t be too quick to dismiss the common bedbug as merely a pestiferous six-legged blood-sucker.

Think of it, rather, as Cimex lectularius, international arthropod of mystery.

In comparison to other insects that bite man, or even only walk across man’s food, nibble man’s crops or bite man’s farm animals, very little is known about the creature whose Latin name means — go figure — “bug of the bed.” Only a handful of entomologists specialize in it, and until recently it has been low on the government’s research agenda because it does not transmit disease. Most study grants come from the pesticide industry and ask only one question: What kills it?

What Created This Smooth, 200-Mile-Long Trench On Mars?

Orcus Patera ESA

From Popular Science:

The European Space Agency has released a series of new images of Orcus Patera, a long crater near Mars's Mons Olympus whose rim rises some 6,000 feet. But the images, taken by the Mars Express craft, only deepen the mystery of the crater's origin.

The ESA says "the most likely explanation is that it was made in an oblique impact, when a small body struck the surface at a very shallow angle." Sounds almost definitely like aliens.

How the 105-mph Fastball Tests The Limits Of The Human Body

From Popular Mechanics:

A Triple-A pitcher shocked the baseball world with a pitch clocked at an insanely fast 105 mph. Here's why we won't see pitchers throw it much faster than this—ever.

Last Friday was a mixed bag for fans of the fastball. Early in the day, the Washington Nationals announced that phenom Stephen Strasburg, who hurled a 101-mph pitch in his debut in June, would likely require Tommy John surgery for his injured elbow; a procedure that could sideline him for up to 18 months. But later that night Aroldis Chapman, a 22-year-old Cuban defector pitching for the Cincinnati Reds' triple-A affiliate in Louisville, captured baseball fans' attention when he threw a pitch clocked at 105 mph.

Organic food comes with real health benefits and significant costs. TIME looks at both sides of the debate

From Time Magazine:

Looking for a quick way to feel lousy about yourself? Then forget the idea of a healthy diet and just eat what your body wants you to eat. Your body wants meat; your body wants fat; your body wants salt and sugar. Your body will put up with fruits and vegetables if it must, but only after all the meat, fat, salt and sugar are gone. And as for the question of where your food comes from — whether it's locally grown, sustainably raised, grass-fed, free range or pesticide-free? Your body doesn't give a hoot.

Yet Another Human Job Is Replaced By A Robot

EMILY To the Rescue: An Automated Lifeguard -- The Economist

Yet another human job is replaced by a robot.

BIG crowds, strong surf and powerful rip currents are only a few of the obstacles that lifeguards must overcome to keep swimmers safe. Strong winds can pull many bathers out to sea simultaneously, overwhelming the guards if there are only a few of them. And, since average swimming speed is about 3kph (2mph) even a single rescue mission can take more than half an hour.

Scientists Figure Out Magical 'Banana' Free Kick

From The CBC:

Thirteen years after Roberto Carlos stunned onlookers with his amazing "banana" free kick that seemed to defy the law of physics, scientists have finally worked out how he did it.

In what many people regard as the best free kick ever, the Brazil defender struck the ball with the outside of his left foot 35 yards out, bending it around the outside of France's three-man wall during a friendly tournament in Lyon in 1997.

From Science Daily:

ScienceDaily (Sep. 2, 2010) — Earth today is one of the most active planets in the Solar System, and was probably even more so during the early stages of its life. Thanks to the plate tectonics that continue to shape our planet's surface, remnants of crust from Earth's formative years are rare, but not impossible to find. A paper published in Nature Sept. 2 examines how some ancient rocks have resisted being recycled into Earth's convecting interior.

From Live Science:

The Magna Carta helped form the foundation for modern English and U.S. law. Now one of two copies known to exist outside England is headed for a special new case to preserve it.

The very first Magna Carta dates to 1215, when English barons forced King John to write down the traditional rights and liberties of the country's free persons. A copy of the Magna Carta signed by King Edward I in 1297 currently resides within a helium-filled casement at the National Archives Building in Washington. But the medieval document is scheduled for a temporary removal in 2011 so it can be re-measured for a new case filled with argon.

NASA Flies First Drone Over Hurricane

From Wired Science:

Hurricane Earl is waning as it moves northward up the east coast of the United States. Some of the first researchers to notice the weakening had front row seats, watching the eye of the hurricane via drone flights.

In addition to the usual cadre of satellites, NASA is using a small fleet of unmanned aircraft into, over and around the hurricane as it tracks north from the Caribbean. While flying into a hurricane is nothing new, Earl is the first hurricane that NASA has observed using their unmanned Global Hawk observation aircraft (pictured above).

Why Do Heavy Drinkers Outlive Nondrinkers?

From Time Magazine:

One of the most contentious issues in the vast literature about alcohol consumption has been the consistent finding that those who don't drink tend to die sooner than those who do. The standard Alcoholics Anonymous explanation for this finding is that many of those who show up as abstainers in such research are actually former hard-core drunks who had already incurred health problems associated with drinking.

My Comment: I am convinced .... and yes .... I need a drink.

One Reason Dieting Does Not Work

That’s The Way The Cookie Crumbles -- The Economist

One reason dieting does not work.

IF, BY chance, you are served an unusually large slice of pizza, compared with what others appear to be getting, would that experience incline you, some minutes later, to eat more cookies or fewer when platefuls came your way? That depends, it turns out, on whether you are on a diet. Those who are not eat fewer cookies, whereas those who are see the excessive pizza as a licence to pig out. It is a demonstration of what Janet Polivy, a psychologist at the University of Toronto, refers to as the “what the hell” effect—a phenomenon familiar from real life to which Dr Polivy has given scientific respectability, most recently in a paper published in the latest edition of Appetite.

The fight is on over how to solve our food crisis, but if we choose the wrong food policy at this juncture there could be no going back, says Rose Prince.

Hardly a morning passes without food making the headlines. This week has brought us the burger that thinks it's a pizza and news that eating asparagus makes you stay slim (fingers crossed it's the type covered in melted butter). And we heard that, if you eat pickled squid guts and single cream together, it tastes like strawberry shortcake.

Samsung Galaxy Tab: Firm Joins Forces With Google By Launching Tablet to Take On Apple's iPad

iPad killer? People compare the performance of Apple's iPad (L) and Samsung's Galaxy Tab tablet devices at the IFA consumer electronics fair in Berlin today

From The Daily Mail:

Apple faces a killer blow to its iPad after Samsung unveiled its own device amid rumours it could could be just half the price.

The Samsung Galaxy Tab with its seven inch touchscreen is smaller than the iPad, however it matches the Apple device in virtually all other functions.

Initial details suggest some aspects of the Tablet are even more sophisticated than the Apple creation.

At the same time, Apple faces competition from other technology giants which are racing to get their own touchscreen tablets into the shops before Christmas.
