Clusterfuck Nation by Jim Kunstler

Read his 'right-on book' 2 1/2 years ago, we should wake up 'sheeples'

'The Long Emergency'


Easthampton Burning?

In the typhoon of commentary that's blown around the world a step behind the financial tsunami that's wrecking everything, two little words have been curiously absent: "fraud" and "swindle." But aren't they really at the core of what has happened? Wall Street took the whole world "for a ride" and now a handful of Wall Street's erstwhile princelings have shifted ceremoniously into US Government service to "fix" the problem with a "toolbox" containing a notional two trillion dollars. This strange exercise in financial kabuki theater will shut down sometime between the election and inauguration day, when the inaugurate finds himself president of the Economic Smoking Wreckage of the United States. What will happen?

10 Things the Food Industry Doesn't Want You to Know

1. Junk food makers spend billions advertising unhealthy foods to kids.
According to the Federal Trade Commission, food makers spend some $1.6 billion annually to reach children through the traditional media as well the Internet, in-store advertising, and sweepstakes. An article published in 2006 in the Journal of Public Health Policy puts the number as high as $10 billion annually. Promotions often use cartoon characters or free giveaways to entice kids into the junk food fold. PepsiCo has pledged that it will advertise only "Smart Spot" products to children under 12.

2. The studies that food producers support tend to minimize health concerns associated with their products.
In fact, according to a review led by Ludwig of hundreds of studies that looked at the health effects of milk, juice, and soda, the likelihood of conclusions favorable to the industry was several times higher among industry-sponsored research than studies that received no industry funding. "If a study is funded by the industry, it may be closer to advertising than science," he says.

3. Junk food makers donate large sums of money to professional nutrition associations.
The American Dietetic Association, for example, accepts money from companies such as Coca-Cola, which get access to decision makers in the food and nutrition marketplace via ADA events and programs, as this release explains. As Nestle notes in her blog and discusses at length in her book Food Politics, the group even distributes nutritional fact sheets that are directly sponsored by specific industry groups. This one, for example, which is sponsored by an industry group that promotes lamb, rather unsurprisingly touts the nutritional benefits of lamb. The ADA's reasoning: "These collaborations take place with the understanding that ADA does not support any program or message that does not correspond with ADA's science-based healthful-eating messages and positions," according to the group's president, dietitian Martin Yadrick. "In fact, we think it's important for us to be at the same table with food companies because of the positive influence that we can have on them."

4. More processing means more profits, but typically makes the food less healthy.
Minimally processed foods such as fresh fruits and vegetables obviously aren't where food companies look for profits. The big bucks stem from turning government-subsidized commodity crops--mainly corn, wheat, and soybeans--into fast foods, snack foods, and beverages. High-profit products derived from these commodity crops are generally high in calories and low in nutritional value.

5. Less-processed foods are generally more satiating than their highly processed counterparts.
Fresh apples have an abundance of fiber and nutrients that are lost when they are processed into applesauce. And the added sugar or other sweeteners increase the number of calories without necessarily making the applesauce any more filling. Apple juice, which is even more processed, has had almost all of the fiber and nutrients stripped out. This same stripping out of nutrients, says Ludwig, happens with highly refined white bread compared with stone-ground whole wheat bread.

6. Many supposedly healthy replacement foods are hardly healthier than the foods they replace.
In 2006, for example, major beverage makers agreed to remove sugary sodas from school vending machines. But the industry mounted an intense lobbying effort that persuaded lawmakers to allow sports drinks and vitamin waters that--despite their slightly healthier reputations--still can be packed with sugar and calories.

7. A health claim on the label doesn't necessarily make a food healthy.
Health claims such as "zero trans fats" or "contains whole wheat" may create the false impression that a product is healthy when it's not. While the claims may be true, a product is not going to benefit your kid's health if it's also loaded with salt and sugar or saturated fat, say, and lacks fiber or other nutrients. "These claims are calorie distracters," adds Nestle. "They make people forget about the calories." Dave DeCecco, a spokesperson for PepsiCo, counters that the intent of a labeling program such as Smart Spot is simply to help consumers pick a healthier choice within a category. "We're not trying to tell people that a bag of Doritos is healthier than asparagus. But, if you're buying chips, and you're busy, and you don't have a lot of time to read every part of the label, it's an easy way to make a smarter choice," he says.

8. Food industry pressure has made nutritional guidelines confusing.
As Nestle explained in Food Politics, the food industry has a history of preferring scientific jargon to straight talk. As far back as 1977, public health officials attempted to include the advice "reduce consumption of meat" in an important report called Dietary Goals for the United States. The report's authors capitulated to intense pushback from the cattle industry and used this less-direct and more ambiguous advice: "Choose meats, poultry, and fish which will reduce saturated fat intake." Overall, says Nestle, the government has a hard time suggesting that people eat less of anything.

9. The food industry funds front groups that fight antiobesity public health initiatives.
Unless you follow politics closely, you wouldn't necessarily realize that a group with a name like the Center for Consumer Freedom (CCF) has anything to do with the food industry. In fact,Ludwig and Nestle point out, this group lobbies aggressively against obesity-related public health campaigns--such as the one directed at removing junk food from schools--and is funded, according to the Center for Media and Democracy, primarily through donations from big food companies such as Coca-Cola, Cargill, Tyson Foods, and Wendy's.

10. The food industry works aggressively to discredit its critics.
According to the new JAMA article, the Center for Consumer Freedom boasts that "[our strategy] is to shoot the messenger. We've got to attack [activists'] credibility as spokespersons." Here's the group's entry on Marion Nestle.

The bottom line, says Nestle, is quite simple: Kids need to eat less, include more fruits and vegetables, and limit the junk food.

Future planes, cars may be made of `buckypaper'



It's called "buckypaper" and looks a lot like ordinary carbon paper, but don't be fooled by the cute name or flimsy appearance. It could revolutionize the way everything from airplanes to TVs are made.

Buckypaper is 10 times lighter but potentially 500 times stronger than steel when sheets of it are stacked and pressed together to form a composite. Unlike conventional composite materials, though, it conducts electricity like copper or silicon and disperses heat like steel or brass.

"All those things are what a lot of people in nanotechnology have been working toward as sort of Holy Grails," said Wade Adams, a scientist at Rice University.

That idea — that there is great future promise for buckypaper and other derivatives of the ultra-tiny cylinders known as carbon nanotubes — has been floated for years now. However, researchers at Florida State University say they have made important progress that may soon turn hype into reality.

Buckypaper is made from tube-shaped carbon molecules 50,000 times thinner than a human hair. Due to its unique properties, it is envisioned as a wondrous new material for light, energy-efficient aircraft and automobiles, more powerful computers, improved TV screens and many other products.

So far, buckypaper can be made at only a fraction of its potential strength, in small quantities and at a high price. The Florida State researchers are developing manufacturing techniques that soon may make it competitive with the best composite materials now available.

"If this thing goes into production, this very well could be a very, very game-changing or revolutionary technology to the aerospace business," said Les Kramer, chief technologist for Lockheed Martin Missiles and Fire Control, which is helping fund the Florida State research.

The scientific discovery that led to buckypaper virtually came from outer space.

In 1985, British scientist Harry Kroto joined researchers at Rice University for an experiment to create the same conditions that exist in a star. They wanted to find out how stars, the source of all carbon in the universe, make the element that is a main building block of life.

Everything went as planned with one exception.

"There was an extra character that turned up totally unexpected," recalled Kroto, now at Florida State heading a program that encourages the study of math, science and technology in public schools. "It was a discovery out of left field."

The surprise guest was a molecule with 60 carbon atoms shaped like a soccer ball. To Kroto, it also looked like the geodesic domes promoted by Buckminster Fuller, an architect, inventor and futurist. That inspired Kroto to name the new molecule buckminsterfullerene, or "buckyballs" for short.

For their discovery of the buckyball — the third form of pure carbon to be discovered after graphite and diamonds — Kroto and his Rice colleagues, Robert Curl Jr. and Richard E. Smalley, were awarded the Nobel Prize for chemistry in 1996.

Separately, Japanese physicist Sumio Iijima developed a tube-shaped variation while doing research at Arizona State University.

Researchers at Smalley's laboratory then inadvertently found that the tubes would stick together when disbursed in a liquid suspension and filtered through a fine mesh, producing a thin film — buckypaper.

The secret of its strength is the huge surface area of each nanotube, said Ben Wang, director of Florida State's High-Performance Materials Institute.

"If you take a gram of nanotubes, just one gram, and if you unfold every tube into a graphite sheet, you can cover about two-thirds of a football field," Wang said.

Carbon nanotubes are already beginning to be used to strengthen tennis rackets and bicycles, but in small amounts. The epoxy resins used in those applications are 1 to 5 percent carbon nanotubes, which are added in the form of a fine powder. Buckypaper, which is a thin film rather than a powder, has a much higher nanotube content — about 50 percent.

One challenge is that the tubes clump together at odd angles, limiting their strength in buckypaper. Wang and his fellow researchers found a solution: Exposing the tubes to high magnetism causes most of them to line up in the same direction, increasing their collective strength.

Another problem is the tubes are so perfectly smooth it's hard to hold them together with epoxy. Researchers are looking for ways to create some surface defects — but not too many — to improve bonding.

So far, the Florida State institute has been able to produce buckypaper with half the strength of the best existing composite material, known as IM7. Wang expects to close the gap quickly.

"By the end of next year we should have a buckypaper composite as strong as IM7, and it's 35 percent lighter," Wang said.

Buckypaper now is being made only in the laboratory, but Florida State is in the early stages of spinning out a company to make commercial buckypaper.

"These guys have actually demonstrated materials that are capable of being used on flying systems," said Adams, director of Rice's Richard E. Smalley Institute for Nanoscale Science and Technology. "Having something that you can hold in your hand is an accomplishment in nanotechnology."

It takes upward of five years to get a new structural material certified for aviation use, so Wang said he expects buckypaper's first uses will be for electromagnetic interference shielding and lightning-strike protection on aircraft.

Electrical circuits and even natural causes such as the sun or Northern Lights can interfere with radios and other electronic gear. Buckypaper provides up to four times the shielding specified in a recent Air Force contract proposal, Wang said.

Typically, conventional composite materials have a copper mesh added for lightning protection. Replacing copper with buckypaper would save weight and fuel.

Wang demonstrated this with a composite model plane and a stun gun. Zapping an unprotected part of the model caused sparks to fly. The electric jolt, though, passed harmlessly across another section shielded by a strip of buckypaper.

Other near-term uses would be as electrodes for fuel cells, super capacitors and batteries, Wang said. Next in line, buckypaper could be a more efficient and lighter replacement for graphite sheets used in laptop computers to dissipate heat, which is harmful to electronics.

The long-range goal is to build planes, automobiles and other things with buckypaper composites. The military also is looking at it for use in armor plating and stealth technology.

"Our plan is perhaps in the next 12 months we'll begin maybe to have some commercial products," Wang said. "Nanotubes obviously are no longer just lab wonders. They have real world potential. It's real."

The Right Scents: Smells for Sleep (and Waking Up)


By: Allie Firestone (View Profile)

Fall is chock-full of scents, and that’s one of the reasons I love it. Picking up on the huge variety of smells—whether it’s pumpkin pie, freshly-baked cookies, or spiced apple cider—is something I recently realized that I take for granted.

Scientists say that humans can distinguish over 10,000 different odor molecules. Turns out, while it doesn’t require any conscious thought, our ability to pick up on a scent involves a sensitive and complex function that has powerful effects on our memory and behavior. How else can I explain how one whiff of pumpkin immediately conjures up thoughts of trick-or-treating and holiday gatherings? Scientists dedicated to tracking the complex relationship between smells, our behavior, and our moods have found that certain scents trigger feelings, including those that help us relax and fall asleep and those that perk us up and keep us alert and focused.

Sleep and Relaxation
Looks like I’m not the only one tossing and turning—according to the National Sleep Foundation, over 60 percent of Americans get less than eight hours per night, and over 40 percent say they’re too tired to perform well at work at least a few days each month. Once I’m asleep, I’m totally out (I once slept through a smoke alarm), but it’s the getting there that’s a consistent problem. Smell experts claim the sense of smell offers a natural and cheap solution to the sleep dilemma.

A Wesleyan University study linked the smell of lavender to improved quality of sleep. The study, supported by the Sense of Smell Institute (yes, there is such an institute) showed that certain scents increased the length of time people spent in deep sleep—the most restful and restorative phase in our sleep cycle. Lavender proved to help both men and women get more meaningful shut-eye, but the effect was heightened in women. “This better sleep ability may be due to the effects of reproductive hormones in women,” says Dr. Namni Goal, the study’s lead researcher. Before Dr. Goal’s experiments, sleep experts were unsure of lavender’s power to improve sleep, but her study validated the connection. In addition to helping those of us who just want a little extra help getting our eight hours, the study also showed that lavender helps people who are depressed and having abnormal sleeping difficulties.

Not a fan of lavender? Another study, conducted by Dr. Bryan Raudenbush at Wheeling Jesuit University, showed that subjects sleeping in a room with a faint jasmine scent slept more peacefully and felt better rested the next day.

Waking Up and Staying Up
Even when I do get a solid eight hours of sleep, there are still days when I just can’t shake the tired feeling, especially when that three-o’clock-slump rolls around. In an effort to shed some light on this problem, scent researchers have also tested whether there are particular smells that’ll give us an extra boost in the morning or midday. Lucky for us, it looks like there are such smells. (Alas, a girl can have only so much coffee before it just stops working.)

Good news for me (and bad news for my corner coffee shop), it looks like peppermint and lemon have the power to lure us into a state of alert productivity, similar to that of a good cup of java. A study conducted by Dr. Hoel Warm and William Dember showed that workers who got an occasional whiff of peppermint performed better on tasks that required sustained attention.

Japanese companies have already tapped into this in hopes of increasing workers’ moods and productivity. Workplaces have begun providing office aromas through a computerized odor delivery system built into the air conditioning (I kid you not, this is straight from the Sense of Smell Institute). And it’s worked—workers reported increased efficiency in their routine jobs. Warm and Dember also tested the power of peppermint on long-haul truck drivers who (you guessed it) found that the scents, sent through their truck’s air conditioning system, did perk them up on long journeys.

Lemon has also proven powerful with similar alertness-inducing effects. Studies (conducted in both labs and real world scenarios by the Sense of Smell Institute) showed that people exposed to lemony, woody fragrances early in the morning felt an increase in mental stimulation. When the same people were exposed to a floral scent later in the day, they reported an improvement in their concentration. Lemon has also been tested on clerical workers, who made fewer errors after inhaling faint hints of it.

Whether it’s peppermint, lavender, jasmine, or lemon, it seems to me that it’s at least worth testing these out with candles or essential oils (and if sleep’s what you’re after, oil is probably the safer option). Me? I’ve never been much of a lavender girl, but jasmine oil has definitely left me feeling a little more relaxed, and a whiff of lemon in the afternoon does make me refreshed. Whether it’s just a placebo effect or not, I don’t know, but feeling rested when I need to and staying alert when I’ve gotta be—sans sleeping pill addictions, gross-tasting energy drinks, or creepy noise machines—is a worthy investment.

My coffee habit? Well, it’s gonna take a lot more than lavender to kick that one

The Worst 'Healthy' Foods

By David Zinczenko, with Matt Goulding


If you want to lose weight, it may seem like a good idea to trade candy bars for granola bars or to swap bacon and eggs at breakfast for the classic bagel (it’s shaped like a zero; how bad could it be?).

Sadly, it’s just not that simple. Customers’ nutrition knowledge is rising, so food marketers are desperate to attract the right kind of attention from the eating public. So they’re twisting nutritional buzzwords to trick us into eating the kinds of foods that can actually help make us fat. We need to be more careful than ever to make sure we’re feeding ourselves and our families the very best real health foods — not sugar-infused calorie bombs disguised as weight-loss foods.

Read up for our latest batch of dietary phonies. They may look good on the front label, but they’ll get you in the end if you're not careful.

Granola Bar
200 calories
15 g sugars

Eat this instead!
1 oz cheddar cheese with Triscuits
150 calories
5 g sugars

Ever wonder what keeps a granola bar together? The answer: high-fructose corn syrup, which quickly raises blood sugar and cancels out most of the potential benefits the granola almonds and oats might give you. Switch over to good old-fashioned cheese and crackers, and you trade sugar and calories for protein and fiber. It's a big deal that will make you smaller, as will steering clear of the sugar bombs. By the way, these are the most sugar-packed foods in America.

Yogurt with Fruit on the Bottom
190 calories
30 g sugars

Eat this instead!
Plain yogurt with fresh fruit mixed in
110 calories
15 g sugars

Pass on these over-sweetened yogurt cups; they contain as much sugar as a soft drink. Almost all of that comes directly from the “fruit,” which is swimming in high-fructose corn syrup. Yogurt and fruit can be a great way to start your day, but do it yourself by mixing a cup of nonfat plain yogurt with a half cup of mixed berries.

Bagel with Cream Cheese
700 calories
40 g fat
13 g saturated

Eat this instead!
Cheese omelet
425 calories
18 g
6 g saturated

Bagels are bogus. The bread is bad enough, containing 300 calories and 60 grams of carbohydrates, but tack on the liberal cream cheese schmear (by our survey of popular breakfast chains, up to 4 ounces for a single bagel!) and your "harmless" breakfast sandwich weighs in as worse than a Whopper. The omelet swap will save you nearly 300 calories, plus provide a surge of metabolism-boosting protein. And a recent study from the University of Connecticut found that eating eggs can help raise HDL (good) cholesterol. And while you're being vigilant, watch out for the 20 Unhealthiest Drinks in America!

Dried Fruit
175 calories
45 g sugars

Eat this instead!
Fresh fruit, like an apple or a peach
70 calories
15 g sugars

OK, so dried fruit won’t totally derail a day of good eating (unless you down the whole bag of banana chips), but it’s far from being a harmless snack. First, because the dehydrating process sucks most of the volume from the fruit, you can eat cups of the stuff, and 600 calories later, still not feel any fuller. More troubling, though, is the fact that Sun-Maid and Ocean Spray add sugar to the fruit, making Craisins closer to candy than Mother Nature’s original intention. The choice is clear: Stick to the original, straight from the tree.

Fish Sandwich
600 calories
30 g fat
11 g saturated

Eat this instead!
Grilled chicken sandwich
300 calories
13 g fat
4 g saturated

Fish is good for you, except when it’s battered, fried, robed in cheese, and bathed in tartar sauce. The lesson? Even the biggest star can be sabotaged by the supporting cast. To this end, avoid any menu item with the word "crispy," the restaurant industry’s favorite euphemism for “fried.” Make sure your next fish or chicken sandwich is grilled, dressed with fresh produce, and topped with a low-cal barbecue sauce, or even ketchup and mustard. And watch the salt; these 20 foods are the saltiest in America!

Stick margarine (1 Tbsp)
100 calories
11 g fat
2.5 g saturated
2.5 g trans fat

Eat this instead!
Whipped butter (1 Tbsp)
50 calories
6 g fat
1.5 g saturated

In their haste to remove saturated fat from butter, margarine makers created the margarine monster — a dangerous lipid called trans fat, with more dangerous links to heart disease than saturated fat. Pick up whipped butter instead; by whipping air into the spread, manufacturers decrease the caloric density of a tablespoon of butter, and they make it easier to top your toast. If you buy margarine, make sure it’s the type found in the tub, hopefully with an added bonus like omega-3s folded into the mix.
