Tree Wall to halt the Sahara

I read about this ambitious project to try to stop the southward advance of the Sahara desert the other day and thought it was worth a post if for no other reason than the bigh-thinking scale of the project.

Push for 'Great Green Wall of Africa' to halt Sahara

It sounds like it's nothing more than a big idea at this point and there's not alot of support for the effort, I'm inspired by the thinking that drives it - kindof like trying to control mother nature on a continental scale.

Quietly Not Going - On freezing and resuscitation

This article about reviving people from clinical death after "freezing to death" is very interesting. It talks about an experiment with both yeast and worms that shows extreme cold combined with oxygen depravation creates conditions necessary for a high likelihood of resuscitation. If the oxygen is present while freezing though - not so good.

here's a quote from the story:

When subjected to literally freezing temperatures, the embryos of yeast and garden worms do not live, researchers found. A full 99 percent of those in the experiment died after 24 hours of exposure to temperatures just above freezing.

But, when first deprived of oxygen in the manner described above, 66 percent of the yeast and 97 percent of the garden worms survived. Upon re-warming and reintroduction of oxygen, the "two widely divergent organisms" reanimated and showed normal life spans, said scientists in a statement.


Which brings me around to thinking about the cases of people who are able to be revived after disappearing under frozen lakes, or the skier who had a skiing accident and "drowned" trapped with their head underwater in a very cold stream. There are other cases the article mentions where drowning is not central - but people just being exposed to extreme cold to rapidly induce a state of suspended animation as they'd say in Star Trek.

So where's it lead? the article mentions handling of donor organs as an example, but what if somebody is way far away from medical care and is going to die unless these conditions (extreme cold/oxygen deprevation) are induced? Sounds scary, but if it's your only way to have a chance of survival do you do it? I think I recall doctors already using lowering the body temperature as part of the proceedure to improve results in some types of surgery.

Anyhow, thought that was very interesting

Oil dependency

Here's a good op-ed by Thomas Friedman today on how our oil dependency is creating many of the problems we face today, and that we each need to understand our individual role in the problem: This Time is Different.

It'll take a long time, but efforts to move to oil alternatives need to move forward. The problem is that the payoff may not be for 30-50 years. But then I tell myself we had an opportunity back in the 70s to change the course of things, but didn't change then either. Instead we became more dependent. It may not be clear where alternative efforts will lead us, but I think it's pretty clear where the current structure of oil dependency leads.

Confusopoly

I saw the word Confusopoly today for the first time. It's a brilliant concept and word coined by Douglas Adams of Dilbert Fame.

Confusopoly "a group of companies with similar products who intentionally confuse customers instead of competing on price."


Here's a little more info.

We were talking at lunch about how confusing cell phone plans are and that it's nearly impossible to compare what should be a fairly similar product across carriers given all the differences in plans. Our thought was it's intentional complexity designed to confuse shoppers. Confusopoly sums up this business strategy perfectly.

BTW, the term is said also to apply to insurance - the business I'm in too - so don't trust a word I say. And don't pay attention to any new financial products which bundle:
- life insurance,
- an accident benefit,
- savings plan,
- investment plan,
- annuity,
- cash return at retirement,
- free airline miles, and
- a free 12 month subscription to your favorite magazine
in a single product that you couldn't possibly hope to understand without taking a night class.

Corn chips a vegetable?

I was contemplating supper tonight wondering whether I had had any vegetables yet today. I had corn chips at the Mexican place today and thought maybe they were a vegetable? Corn on the cob seems like a vegetable so maybe?

Anyhow, at least this website from University of Missouri says corn chips are not a vegetable but instead a are a grain.

I guess that makes sense in the context that corn decended from grasses like a post a short while ago discusses.

Life on Titan?

Here's an interesting article about some intriguing atmospheric chemistry uncovered during NASA's Callisto mission around Saturn. The moon Titan has some atmospheric characteristics that some scientists intepret as compatible with some type of methane based alien life.

Here's the story on the new research from Science News: Life on Titan? New Clues to What's Consuming Hydrogen, Acetylene on Saturn's Moon

Limits of motivators

Here's an interesting speech from TED that discusses the limits of traditional motivational techniques. The basic argument is that studies are showing that for a range of tasks that are ill-defined and require creativity carrot/stick type motivators can actually reduce productivity.

This video is long (18+min), worth a listen though:

The history of corn

I thought this was an interesting article, discussing research into the genetics of corn to find it's wild ancestor which looks to be from a grass from what is now Mexico - probably started becoming domesticated about 9000 years ago. There's a very cool photo if you want to see what the first corn farmers started with.

It's pretty amazing what they started with.

Brush twice a day

Here's an interesting study that finds brushing teeth twice a day can significantly cut heart disease risk.

From the article regarding the study to be published soon in British Medical Journal:

Neglecting to brush twice a day could lead to a 70 percent increased risk of cardiovascular disease, according to a new large population-based study.


The hypothesis seems to be that maybe inflammation is associate with heart disease and promoting good dental hygiene can reduce one of the more common chronic sources of inflammation in the body (periodontal disease).

Anyhow, thought that was interesting

Hardware disease in cattle?

At first I laughed when I saw this ebay auction for an Alnico Magnet to help prevent hardware disease in cattle. My first thought was that New Age remedies have made it to livestock.... And "hardware disease"? really?

So I think about it for a while and do a web search and it turns out this seems for real. Cattle apparently will eat metal pieces they encounter and potentially infect/inflame their digestive tract. The magnets are fed to cows to stay in the stomach and keep the eaten metal from moving on into the more sensitive parts of the digestive tract where it can cause problems - or at least that's what's claimed. Seems plausible I guess. I'd never heard of it though. There's a wikipedia entry.

Developing World

A good editorial by Nick Kristof today in the Times. Not politically correct, but good. There's probably lots of ways to interpret it and it's probably too easy to just be critical and dismissive, but I just wanted to the it out there as I found it a very interesting read about spending decisions and priorities of the very poor in the third world. Moonshine or the Kids?

Something part 2

I was wondering a few weeks ago about "Why something instead of nothing?" and it turns out some physicists may have uncovered some new science behind why there's something here.

... not that I understand any of it, mind you, but I do find it interesting that if the unexpected finding is confirmed, the conditions of the very early universe seem to slightly favor something over nothing. But why this would be so just begs the question.

Burgess Shale

The story of the Cambrian explosion and some of the earliest forms of "bigger" life told in Stephen Jay Gould's book "Wonderful Life" is one of the more memorable things I read when I was about 20yrs old. I'd always liked Gould's scientific essays, but this was a full book on some of the craziest looking creatures I could imagine that they found in some shale in Canada's Burgess Shale.

CLICK HERE FOR SOME IMAGES - You've probably seen a TV show or pics of some of these strange creatures before.

I remember in the book he talked about how it was kindof a mystery why all this life exploded onto the scene and then seemingly disappeared from the fossil record. One of the working theories was that a major extinction event knocked many of the creatures out and that life had a false start and started over.

Well it turns out some descendants of the cambrian explosion have been found in Morocco - indicating that they survived and that probably the difficulty of fossilization of soft body parts is the reason for their scarcity in the fossil record. Here's the story.
