80 Min Exercise Per Week Prevents Visceral Weight Gain

From Future Pundit:

Fat around your internal organs is thought to be a much bigger risk factor for heart disease than fat near the surface of the skin. Well, if you go on a diet, exercise, get your weight down, and then eventually go off the diet continued exercise will prevent the resulting weight gain from happening where the risk factor is greatest.

BIRMINGHAM, Ala. - A study conducted by exercise physiologists in the University of Alabama at Birmingham (UAB) Department of Human Studies finds that as little as 80 minutes a week of aerobic or resistance training helps not only to prevent weight gain, but also to inhibit a regain of harmful visceral fat one year after weight loss.

The study was published online Oct. 8 and will appear in a future print edition of the journal Obesity.

The Fourth Part Of The World: The Epic Story Of History’s Greatest Map By Toby Lester

From Times Online:

In 2003, the US Library of Congress spent $10m on a beautiful world map, created in 1507. The price was justified by a single, magical name, inscribed in capitals on a strange tract of blank space in the far west: “AMERICA”. As Toby Lester tells in this boundlessly engaging book, this map was not just the first to give America a name, it was the very first to show it as a continent, separated from Asia by a new ocean.

Advertising its purchase, Congress called the map “America’s birth certificate”; Lester rates its importance much less narrowly. It charts an astonishing shift in world-view, he argues, from the Europe-centred, God-driven world of the Middle Ages to the brave new imperial vision of the early modern age.

Advances in technological therapy.

Born in Belgrade, in what was then Yugoslavia, Maja Matarić originally wanted to study languages and art. After she and her mother moved to the United States, in 1981, her uncle, who had immigrated some years earlier, pressed her to concentrate on computers. As a graduate student at the Massachusetts Institute of Technology, Matarić wrote software that helped robots to independently navigate around obstacles placed randomly in a room. For her doctoral dissertation, she developed a robotic shepherd capable of corralling a herd of twenty robots.

America's Natural Gas Revolution -- A Commentary

From Wall Street Journal:

A 'shale gale' of unconventional and abundant U.S. gas is transforming the energy market.

The biggest energy innovation of the decade is natural gas—more specifically what is called "unconventional" natural gas. Some call it a revolution.

Yet the natural gas revolution has unfolded with no great fanfare, no grand opening ceremony, no ribbon cutting. It just crept up. In 1990, unconventional gas—from shales, coal-bed methane and so-called "tight" formations—was about 10% of total U.S. production. Today it is around 40%, and growing fast, with shale gas by far the biggest part.

Now, scientists from several countries have confirmed that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world's oceans, and the rift is indeed likely the beginning of a new sea.

Caffeine Cuts Into Sleep, Even Hours Later

Add one more insult to the injury of working the night shift: Drinking coffee during work hours may just keep you awake during the day.

"Caffeine is the most widely used stimulant to counteract sleepiness, yet it has detrimental effects on the sleep of night-shift workers who must slumber during the day, just as their biological clock sends a strong wake-up signal," said Julie Carrier, a University of Montreal psychology professor.

Sniffing Out Swine Flu

From Slate:

Researchers hope to create a better way to diagnose swine flu and other ailments.

Crude methods of detecting swine flu have so far provoked hand-wringing and no small amount of ridicule. Planeloads of travelers to China have had laser beams aimed at their foreheads, landing some under quarantine (and spurring a YouTube minifest of airport videos). This summer, Slate reported on a camp that tried to prescreen kids for flu by checking campers for fevers—and failed to detect a sick child whose physician parent brought his temperature down with Tylenol, fueling an outbreak. Meanwhile, people infected with the virus can pass it on before they develop symptoms; others never develop fever at all.

Clever Fools: Why A High IQ Doesn't Mean You're Smart

There's more to intelligence than just IQ. (Image: David C Ellis/Getty)

From New Scientist:

IS GEORGE W. BUSH stupid? It's a question that occupied a good many minds of all political persuasions during his turbulent eight-year presidency. The strict answer is no. Bush's IQ score is estimated to be above 120, which suggests an intelligence in the top 10 per cent of the population. But this, surely, does not tell the whole story. Even those sympathetic to the former president have acknowledged that as a thinker and decision-maker he is not all there. Even his loyal speechwriter David Frum called him glib, incurious and "as a result ill-informed". The political pundit and former Republican congressman Joe Scarborough accused him of lacking intellectual depth, claiming that compared with other US presidents whose intellect had been questioned, Bush junior was "in a league by himself". Bush himself has described his thinking style as "not very analytical".

How The Ancient Nazca Civilisation Sealed Its Own Fate By Cutting Down Forests C

An ancient geoglyph of a hummingbird (colibri in Spanish) on the edge to the Nazca plains was probably inscribed here as an offering for water/fertility in the fields that lie below

From The Daily Mail:

The mysterious people who etched the strange network of 'Nazca Lines' across deserts in Peru hastened their own demise by clearing forests 1,500 years ago, according to British scientists.

The Nazca people, famed for giant animal drawings most clearly visible from the air, became unable to grow enough food in nearby valleys because the lack of trees made the climate too dry.

Archaeologists examining the remains of the Nazca, who once flourished in the valleys of south coastal Peru, discovered a sequence of human-induced events which led to their 'catastrophic' collapse around 500 AD.

Lions Had A Taste For Human Flesh

Hungry for Humans. In 1898, two man-eating lions terrorized railway workers, claiming 35 lives. The remains of the two lions are now on display at the Field Museum of Natural History in Chicago. Getty Images

From Discovery News:

The nightly attacks by two man-eating lions terrified railway workers and brought construction to a halt in one of east Africa's most notorious onslaughts more than a hundred years ago. But the death toll, scientists now say, wasn't as high as previously thought.

Over nine months the two voracious hunters claimed 35 lives -- no small figure, but much less than some accounts of as many as 135 victims.

It was 1898, when laborers from India and local natives building the Uganda Railroad across Kenya became the prey for the pair, a case that has been the subject of numerous accounts and at least three movies.

From Technology Review:

Transportation defines our civilization. Where we live and work, the structure of our cities, the flow of global commerce--all have been shaped by transportation technologies. But modern transportation's reliance on fossil fuels cannot be sustained. Passenger planes, trains, and automobiles were responsible for nearly four billion tons of carbon dioxide emissions in 2005--about 14 percent of the carbon dioxide emitted globally that year. If we continue to rely almost exclusively on petroleum to power these vehicles, they will be responsible for 11 billion to 18 billion tons of carbon dioxide emissions in 2050. That's because developing nations--which are home to 82 percent of the world's population and will be responsible for 98 percent of population growth in coming years--are on the verge of mass motorization. Auto ownership in the developing world is growing at a rate of 30 percent per year (see "Cleaner Vehicles by the Million").
