From Washington Post:

Nation plans astronaut-training center, manned space mission as it seeks higher profile.

PANNITHITTU, India -- In this seaside village, the children of farmers and fishermen aspire to become something that their impoverished parents never thought possible: astronauts.

Through community-based programs, India's space agency has been partnering with schools in remote areas such as this one, helping to teach students about space exploration and cutting-edge technology. The agency is also training thousands of young scientists and, in 2012, will open the nation's first astronaut-training center in the southern city of Bangalore.

Gene-Makers Put Forward Security Standards

From Scientific American:

But few companies are willing to sign up yet.

Several gene-synthesis companies yesterday finalized a code of conduct that outlines how to screen orders for synthetic DNA that could be used for terrorist activities.

The code, which has been in the works from the International Association of Synthetic Biology (IASB) in Heidelberg, Germany, for a year and a half, reflects for the most part what has become common practice in gene-synthesis companies. Before filling orders, the firms compare the gene sequences with those from organisms on lists of pathogens, such as the US Centers for Disease Control and Prevention's select-agents list. Most companies then follow up 'hits' with human investigation of whether the match is valid and the purchaser is legitimate.

The Hidden Uses of Everyday Explosives

Impact Study The slug and gunpowder have been removed from the cartridge, so it’s only the primer that’s going off when it’s hit from below by the point of a center punch (triggered by pulling a string from a safe distance). Mike Walker

From Popular Science:

When you stop and look, you may be surprised to find yourself surrounded by all kinds of explosives--some that detonate easier than dynamite.

The explosive C4, a favorite for everything from demolition to terrorism to action movies, is in fact one of the safest explosives. How can an explosive be safe? If it’s hard to set off by accident. C4 is so stable that you can light it with a match (it burns but does not explode) or shoot it (it splatters but does not explode). To go bang, it requires a detonator that produces both heat and shock.

From Technology Review:

A large-scale trial will test whether software can identify depressed patients.

It's a common complaint in any communication breakdown: "It's not what you said, it's how you said it." For professor Sandy Pentland and his group at MIT's Media Lab, the tone and pitch of a person's voice, the length and frequency of pauses and speed of speech can reveal much about his or her mood.

While most speech recognition software concentrates on turning words and phrases into text, Pentland's group is developing algorithms that analyze subtle cues in speech to determine whether someone is feeling awkward, anxious, disconnected or depressed.

From The Guardian:

Chinese scientists claim to be able to control the weather. But is so-called geoengineering more than wishful thinking? And, if so, should we be worried?

The unseasonal snow that fell on Beijing for 11 hours on Sunday was the earliest and heaviest there has been for years. It was also, China claims, man-made. By the end of last month, farmland in the already dry north of China was suffering badly due to drought. So on Saturday night China's meteorologists fired 186 explosive rockets loaded with chemicals to "seed" clouds and encourage snow to fall. "We won't miss any opportunity of artificial precipitation since Beijing is suffering from a lingering drought," Zhang Qiang, head of the Beijing Weather Modification Office, told state media.

Ares' Continued Technical Problems And Money Troubles: Guest Analysis

From Popular Mechanics:

Space analyst Rand Simberg argues here that last week's test flight of the Ares I-X rocket, NASA's planned, vaunted crew-launch system, did little to stem the controversy over the program. The space agency claims that the flight was a success, providing data needed to retire some of the risk in the development of the eventual booster. But the flight was hardly flawless, Simberg says, and may have uncovered a previously unknown (or, at any rate, undiscussed) risk. Even with all of its technical issues—thrust oscillation, reduced performance margin, a gantry collision risk and now a risk during stage separation—the real problem of the program, Simberg argues, remains how much it will cost.

Guzzling Food Makes You Fat

Eating quickly makes you put on weight Photo: GETTY

From The Telegraph:

Eating quickly makes you put on weight because your stomach does not have time to tell your brain it is full, scientists find.

Researchers found that "wolfing down" your food slows and restricts the release of a special "full up" hormone in your stomach.

That means that you eat more food before the brain realises that your body has already had enough to eat.

The decreased release of these hormones, can often lead to overeating, the researchers concluded.

Drink Responsibly: Which Is Better For The Planet, Beer Or Wine?

From Slate:

I'm hosting a dinner party next week, and I'll be serving both beer and wine alongside the meal. But it got me wondering: Which has the lower carbon footprint? Beer has to be kept refrigerated, which requires energy, but shipping wine in those heavy bottles can't be good for the planet, either.

It's hard to come up with a simple answer for this one, because so many factors affect the calculation: Where was your beverage made? What's it packaged in, and how did that package get to you? How was it stored at the point of sale? Accounting for all these variables can make your head spin, but the best available research suggests that parsing out the difference might not be worth the headache.

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.

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.

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".

Analyses of a partial skeleton of a female Ardipithecus ramidus nicknamed Ardi, suggest the early human would have stood at just under 4 feet (1.2 meters) tall with both primitive traits, such as a small brains size similar to living chimpanzees and those shared with later hominids, such as bipedal posture.

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.

From Technology Review:

For the next few decades at least, liquid hydrocarbons--gasoline, diesel, and jet fuel--will continue to be the mainstays of transportation. They're cheap; refueling is fast; and their energy density, crucial to long-distance travel, is hard to beat.

"Advanced technology is going to happen slowly," says Daniel Sperling, the director of the Institute for Transportation Studies at the University of California at Davis and a member of the California Air Resources Board. "The focus needs to be on making conventional technology more efficient."
