John Michael Greer writes: In the southern Oregon town where I live, Tuesday is the day of the weekly grower’s market, and so yesterday, as we do nearly every Tuesday between March and November, my wife Sara and I walked the 3/4 of a mile or so to the National Guard armory parking lot where local growers and ranchers sell their produce. Among our purchases was a flat of fresh raspberries, and this afternoon we’ll be turning those into home-canned raspberry jam for the year to come.

Now it’s unquestionably true that we could just buy an equivalent volume of commercially manufactured raspberry jam and eat that instead. Still, these two ways of putting by a supply of raspberry jam are by no means equal. Set aside for a moment the higher quality of homemade jam, which (in this case, at least) is made of fresher ingredients and prepared in small batches; one of the most important differences between the two processes is that the homemade jam represents a much more efficient use of fossil fuels.

The grower who produced the raspberries used organic methods, which saved the petroleum and natural gas that would otherwise have had to go into pesticides and fertilizers. While she used a pickup to bring her crop to the market, the ten miles or so she drove compares favorably to the thousands of miles agricultural products are routinely shipped in their journey from farm to factory, warehouse, and supermarket, and even if we owned a car and drove to and from the market, the extra mile and a half of gas wouldn’t shift the balance much.

Turning berries into jam and canning the result probably takes about an equal amount of energy per pint of jam whether it’s done in a home kitchen or a huge factory, though it’s a lot easier to provide the energy via a solar cooker or other renewable source on a small scale. Even without that, though, the homemade jam takes a small fraction of the energy to go from raspberry canes to our pantry than commercial jam requires. One measure of these energy economies is that, including all expenses, our homemade jam costs us only about two-thirds as much as the same volume of commercial jam.

Compare the homemade jam with its commercial equivalent from the viewpoint of conventional economic measures, though, and the balance swings the other way. In terms of its impact on the gross domestic product – generally considered the broadest measure of national prosperity – our homemade jam is practically an economic disaster. The very modest price of raspberries, sugar, pectin, and new lids for our much-recycled canning jars is the only contribution it makes to the economy. By contrast, making, shipping, storing, and selling the commercial jam requires, directly and indirectly, the expenditure of a very large amount of money, all of which counts mightily toward a higher gross domestic product.

Consider the economics from the perspective of the participants in the creation of the homemade jam, though, and things take on a very different shape. Even aside from the other reasons Sara and I might want homemade jam, we have a potent economic motive; by making the jam ourselves we get a superior product at a lower price. The raspberry grower, in turn, benefits handsomely from the same decision; the price she gets for her berries when sold directly to the consumer is several times the price she can get from wholesalers. According to conventional economics, the end result of individuals freely pursuing their own interest in a market should be the maximization of prosperity – and yet if prosperity is measured by the gross domestic product, our free pursuit of our own interest decreases our contribution to national prosperity.

Naomi Klein writes: So far, the Olympics have been an open invitation to China-bash, a bottomless excuse for Western journalists to go after the Commies on everything from internet censorship to Darfur. Through all the nasty news stories, however, the Chinese government has seemed amazingly unperturbed. That’s because it is betting on this: when the opening ceremonies begin friday, you will instantly forget all that unpleasantness as your brain is zapped by the cultural/athletic/political extravaganza that is the Beijing Olympics.

Like it or not, you are about to be awed by China’s sheer awesomeness.

The games have been billed as China’s “coming out party” to the world. They are far more significant than that. These Olympics are the coming out party for a disturbingly efficient way of organizing society, one that China has perfected over the past three decades, and is finally ready to show off. It is a potent hybrid of the most powerful political tools of authoritarianism communism — central planning, merciless repression, constant surveillance — harnessed to advance the goals of global capitalism. Some call it “authoritarian capitalism,” others “market Stalinism,” personally I prefer “McCommunism.”

The Beijing Olympics are themselves the perfect expression of this hybrid system. Through extraordinary feats of authoritarian governing, the Chinese state has built stunning new stadiums, highways and railways — all in record time. It has razed whole neighborhoods, lined the streets with trees and flowers and, thanks to an “anti-spitting” campaign, cleaned the sidewalks of saliva. The Communist Party of China even tried to turn the muddy skies blue by ordering heavy industry to cease production for a month — a sort of government-mandated general strike.

As for those Chinese citizens who might go off-message during the games — Tibetan activists, human right campaigners, malcontent bloggers — hundreds have been thrown in jail in recent months. Anyone still harboring protest plans will no doubt be caught on one of Beijing’s 300,000 surveillance cameras and promptly nabbed by a security officer; there are reportedly 100,000 of them on Olympics duty.

BBC Nutritional Science – Eating broccoli could reverse the damage caused by diabetes to heart blood vessels, research suggests.

A University of Warwick team believe the key is a compound found in the vegetable, called sulforaphane. It encourages production of enzymes which protect the blood vessels, and a reduction in high levels of molecules which cause significant cell damage.

Brassica vegetables such as broccoli have previously been linked to a lower risk of heart attacks and strokes. People with diabetes are up to five times more likely to develop cardiovascular diseases such as heart attacks and strokes; both are linked to damaged blood vessels.

The Warwick team, whose work is reported in the journal Diabetes, tested the effects of sulforaphane on blood vessel cells damaged by high glucose levels (hyperglycaemia), which are associated with diabetes. They recorded a 73% reduction of molecules in the body called Reactive Oxygen Species (ROS).

Hyperglycaemia can cause levels of ROS to increase three-fold and such high levels can damage human cells.

The researchers also found that sulforaphane activated a protein in the body called nrf2, which protects cells and tissues from damage by activating protective antioxidant and detoxifying enzymes. Lead researcher Professor Paul Thornalley said: “Our study suggests that compounds such as sulforaphane from broccoli may help counter processes linked to the development of vascular disease in diabetes.
