Although headlines today, including my own, emphasize the study’s findings regarding the impairing effects of high levels of fructose, the study also highlights the importance of n-3 acids, specifically DHA, to cognitive function. The authors of the study conclude: “In terms of public health, these results support the encouraging possibility that healthy diets can attenuate the action of unhealthy diets such that the right combination of foods is crucial for a healthy brain.”

The study, conducted by Rahul Agrawal1 and Fernando Gomez-Pinilla, consisted of four groups of six rats:

• one group ate an n-3 deficient diet with a fructose solution
• one group ate an n-3 deficient diet without a fructose solution
• one group ate an n-3 sufficient diet with a fructose solution
• one group ate an n-3 sufficient diet without a fructose solution

Each group was tested on a Barnes maze, a standard measure of spatial learning and memory in rodents. Prior to beginning their special diets all of the rats had been trained in the maze for a five days were found to be of equal cognitive condition.

The study found that an n-3 deficient diet hampered the rats’ performance on the maze, and that adding high fructose intake to an n-3 deficient diet made things substantially worse. The rats with an n-3 sufficient diet but a high level of fructose did significantly better than those with a n-3 deficient diet and a high level of fructose, but still did worse than those with a deficient n-3 level but no fructose. Here’s an illustration of the latency in completing the maze (lower is better):

The study notes: “Although there was a preference towards fructose drinking in comparison to the food intake, no differences were observed in body weight and total caloric intake, thus suggesting that obesity is not a major contributor to altered memory functions in this model.”

This is a new study and has yet to be replicated, and so far its implications for human diets is unclear. “We’re not talking about naturally occurring fructose in fruits, which also contain important antioxidants,” Gomez-Pinilla told MedicalXPress. “We’re concerned about high-fructose corn syrup that is added to manufactured food products as a sweetener and preservative.”

Although studies have found positive benefits in taking DHA supplements (see Wikipedia for an overview), previous study by Nutritional Sciences Division at King’s College London on the DHA levels in vegans and vegetarians concluded that although those who don’t eat meat have significantly lower levels of DHA “There is no evidence of adverse effects on health or cognitive function with lower DHA intake in vegetarians.” However, there are now a number of algae based vegan DHA supplements.

What makes the approach so powerful is that the mathematics does not depend on the nature of chemistry–it is substrate independent. So the building blocks in an autocatalytic set need not be molecules at all but any units that can manipulate other units in the required way.

These units can be complex entities in themselves. “Perhaps it is not too far-fetched to think, for example, of the collection of bacterial species in your gut (several hundreds of them) as one big autocatalytic set,” say Kauffman and co.

And they go even further. They point out that the economy is essentially the process of transforming raw materials into products such as hammers and spades that themselves facilitate further transformation of raw materials and so on. “Perhaps we can also view the economy as an (emergent) autocatalytic set, exhibiting some sort of functional closure,” they speculate.

Could it be that the same idea–the general theory of autocatalytic sets–can help explain the origin of life, the nature of emergence and provide a mathematical foundation for organisation in economics?

I find this very interesting, but don’t get too excited. These sorts of grand unification theories are extremely elusive. I’m also skeptical of these sorts of models which try to find universal rules for all types of systems.

Last month I performed at Rotture in Portland, OR opening for The Steven Lasombras, along with Cult of Zir and Meta-Pinnacle. I had some technical difficulties in the beginning, so you might want to jump forward to about 3:00 minutes in. It’s hard to tell from the video, but what I’m doing is bowing a broken drum cymbal with a cello bow. I have a contact mic on the cymbal, and the signal is being routed into Ableton Live, where its’ be processed through multiple effects. I have some other noise sources running in Ableton as well.

But here’s some more evidence of what Warren Ellis already found out with Freak Angels. Jim Zubkavich, creator of Skullkickers from Image Comics, started serializing his comic online for free. The results:

Good news: Serializing the issues hasn’t negatively affected our sales one bit. Our trade sales through comic and book stores are up, steadily climbing. Making more people aware of the series has made them want the current material more, not less. Quality and good word of mouth is helping build our readership in shops bit by bit.

Better news: At conventions I’m selling a lot more. I’m not twice the sales person I was last year, but I’m selling more than double the number of books since we started serializing online. 9 times out of 10, I’m selling it to people who read the series online. I asked almost every person who came to my table if they’d heard of Skullkickers before. No word of a lie, when they said “yes”, 90% of those folks also said they were reading it online. It shocked me.

This doesn’t mean, though, that paid digital downloads through tablets wouldn’t cannibalize comic shop sales, but this is indeed good news for creators, publishers and retailers.

JOHN: Right, Taoism has no truck with good and evil at all.

HAKIM: Taoism seems to be the one religion that doesn’t have the Gnostic trace.

JOHN: In our culture, the problem arose with the Romans.

HAKIM: I think it goes further back. It’s Babylon. It’s just like the Rastas say, “It happened in Babylon.” It’s Marduk and Tiamat. It’s Mr. Hard-on God up against Sloppy Mom. In China, chaos is a benevolent property. Huntun is the gourd or the egg out of which everything comes. He’s a wonton. Huntun and wonton are the same words. He’s like this little dumpling and everything good comes out of him. In Babylon, chaos is the disgusting monster vagina that has to be ripped up by Marduk into myriad blobs of shit and slime. And we are those globs of slime. That’s how the human race came into being. What is the purpose of the human race? To serve Marduk, to serve the masculine principle, to store up grain in the granary for the priests, to pay for the priests for their sacrifice so they get the free hamburgers. That’s the whole Western myth. It’s St. George and the Dragon. St. George pins the dragon down.

In China, the dragon is the free expression of creativity. He’s the mixture of Yin and Yang, the principle of power. But here’s evil, plain and simple. This is why chaos has kicked off, for me, for Ralph Abraham, and others, an interest in making a critique of this Western mythology, and saying, “Let’s put Humpty Dumpty back together.”

JOHN: There’s been an interesting co-evolution lately of a lot of apparently disconnected things, like chaos mathematics and neo-tribalism, a sudden interest in Taoism and what I perceive to be a deep feminization of Western culture.

GEN: Some philosophers feel that there’s a risk in absolute unconditional surrender of that male-God power, even though it’s obviously failed miserably. Should we seek out every possible male trait and subordinate it to a female principle?

HAKIM: I didn’t like the rule of Dad, but I don’t think I’m going to like the rule of Mom either.

Type One: The enterprise scoop. “Where the news would not have come out without the enterprising work of the reporter who dug it out.”

Type Two: The ego scoop. “This is where the news would have come out anyway–typically because it was announced or would have been announced–but some reporter managed to get ahead of the field and break it before anyone else.”

Type Three: The traders scoop. “This is the most ambiguous of my categories. It recognizes that there can be situations in which, for the general public, ‘who got it first?’ is next-to meaningless, but for a special category of user–the traders, investors, arbitrageurs–minutes and even seconds can count.”

Type Four: The thought scoop. “The most under-recognized type of scoop is the intellectual scoop: ‘stories with new insights’ that coin terms, define trends, or apprehend–name and frame–something that’s happening out there… before anyone else recognizes it.”

In my rant Getting Scoops Is Not (Necessarily) the Same as “Doing Journalism”., I’m basically talking about the difference between what Rosen calls “enterprise scoops” and “ego scoops.” The thing is, ego scoops do matter financially to tech publications – the first blog to get a story will generally be rewarded with more traffic. Because of that, I don’t judge my fellow tech reporters chasing these sorts of scoops, in fact I do it myself. The unfortunate thing though is that the tech journalism community seems to have lost track of the difference between enterprise and ego scoops (as have quit a few other journalistic communities, I take it).

There can be a degree of luck involved in getting enterprise scoops as well. Being the in the right place at the right time when someone mentions something. A lot of the dirty work is actually done by non-profit “wachdog” organizations. But it also means recognizing a real story, and doing the digging and fact checking to turn it into something substantial and not just a quick hit gossip piece. It means developing sources so that you’re the person that gets a tip.

My research team and I investigated time pressure and creativity as part of a multi-year research program in which we had a large number of organizational employees—238 individuals on 26 project teams in 7 companies in 3 industries—fill out a brief electronic diary every day during the entire course of a creative project they were doing in their jobs. [...]

As the HBR article points out, the results suggest that, overall, very high levels of time pressure should be avoided if you want to foster creativity on a consistent basis. However, if a time crunch is absolutely unavoidable, managers can try to preserve creativity by protecting people from fragmentation of their work and distractions; they should also give people a sense of being “on a mission,” doing something difficult but important. I don’t think, though, that most people can function effectively in that mode for long periods of time without getting burned out.

At the other end of the spectrum, very low time pressure might lull people into inaction; under those conditions, top-management encouragement to be creative—to do something radically new—might stimulate creativity. But, frankly, I don’t think there’s much danger of too little time pressure in most organizations I’ve studied.

Undertaking regular jogging increases the life expectancy of men by 6.2 years and women by 5.6 years, reveals the latest data from the Copenhagen City Heart study presented at the EuroPRevent2012 meeting.

Reviewing the evidence of whether jogging is healthy or hazardous, Peter Schnohr told delegates that the study’s most recent analysis (unpublished) shows that between one and two-and-a-half hours of jogging per week at a “slow or average” pace delivers optimum benefits for longevity. [...]

The debate over jogging first kicked off in the 1970s when middle aged men took an interest in the past-time. “After a few men died while out on a run, various newspapers suggested that jogging might be too strenuous for ordinary middle aged people,” recalled Schnohr.

The press release doesn’t talk about how the study controlled for other health factors. Do joggers live longer than swimmers or cyclists? Did the joggers and non-joggers have otherwise similar health habits (diet, tobacco, etc.)?

By his own admission, Daniel Chong planned to spend April 20 like so many other college students: smoking marijuana with friends to celebrate an unofficial holiday devoted to the drug.

But for Mr. Chong, the celebration ended in a Kafkaesque nightmare inside a San Diego Drug Enforcement Administration holding cell, where he said he was forgotten for four days, without food or water.

To survive, Mr. Chong said he drank his own urine, hallucinated and, at one point, considered how to take his own life. By the time agents found him on the fifth day and called paramedics, he said he thought he could be dead within five minutes. [...]

A spokeswoman for the D.E.A. said the case was under investigation, but confirmed that Mr. Chong had been “accidentally left in one of the cells” from April 21 until April 25, and that he had not been charged with a crime.
