glutinous is different from gluten


Glutinous rice does not contain dietary gluten (i.e. does not contain glutenin and gliadin), and thus should be safe for gluten-free diets. What distinguishes it from other types of rice is having no (or negligible amounts of) amylose, and high amounts of amylopectin (those are the two components of starch). Amylopectin is responsible for the sticky quality of glutinous rice.

glutinous rice = sticky rice (that does not contain gluten)
gluten = elastic protein material, especially of wheat flour, that gives cohesiveness to dough

Newark, N.J., Mayor Cory Booker says


That's funny. I said exactly the same thing 25 years ago, and people said, "No, this is normal. Everywhere is like this."

Having lived elsewhere for 40 years, I can now assure them that, no, it is not normal.

Could turning plants upside down make them grow five times better?

Resource depletion as a predator-prey interaction


This is a really interesting idea.

There is also the increasing energy necessary to extract the oil, which was 1 : 1,000,000 in 1860 and is now 1 : 15.



Let's go back to whaling in 19th century; at that time the main problem related to killing whales was finding one. Once it was found, killing it and making whale oil out of it was a relatively quick process. In the case of crude oil, instead, the length of delay between discovering a field and getting oil out of it often amounts to several years. But, the main point is discovery: once a field is discovered, it will be put into production at some point--that's almost automatic. So, prospecting for oil is the main "predation" activity, and also the most expensive one. So, the production parameter in the model is the amount of oil found , not the produced oil. At that point, you can think that a measure of the effort (the capital) placed into prospection is the number of wildcats drilled. Once we found this idea, it was bingo again. The relationship of predator to prey was there, although it was not as good as for whaling. Here are the results for the US 48 lower states (the case studied by Hubbert).

Maybe I am seeing ghosts created by my own mind, but I tend to see many things that I have done in my life in these terms. I see it even with the research grants for my lab, at the university of Florence. Despite having stepped up our efforts, we are getting less and less money to run the lab. "Peak grants" has taken place a few years ago and my lab is being destroyed by the same mechanism that, long ago, brought down the Roman Empire.

1. There exists a non renewable or slowly renewable resource which is limited in amount and "graded" in costs of extraction/production.

2. People will extract/produce first the low cost resource and will re-invest an approximately constant fraction of their profits in more facilities for extraction/production. This is the positive feedback that generates the rapid initial growth of the curve

3. As the resource is consumed, increasing costs of production reduce profits and - as a consequence - investments in extraction/production. This is the negative feedback that generates the decline.

Everything most people "know" about Columbine is wrong


It wasn't supposed to be a shooting; it was supposed to be a bombing.


"The book gained considerable media attention for dispelling the Columbine myths ... the massacre had nothing to do with jocks, Goths, Marilyn Manson or the Trench Coat Mafia. In fact, it was not intended primarily as a school shooting, but as a bombing. Cullen reports that Harris and Klebold intended to perpetrate the worst terrorist attack in American history. The book garnered glowing reviews from Time, Newsweek, People, The New York Observer, and The New York Times Book Review. One of the few dissenting views came from Janet Maslin."



The miracle of compound interest

$100 compounded at 7% for 200 years is more than $100 million, by which time it will be worth nothing.

We were so absorbed in our own problems that we did not even notice this

Absolute must-see.

After a few minutes, you will say to yourself: Hmm... huge foreign debt, bank collapse... why does this sound familiar?

How the crash is rewriting investment rules

They said we would get 8% return on investment in our pension plans... Ha! Madoff level returns.

Now they say 4%.

I think we will be lucky to get 1% because the last 30 years of "normal" growth required 10 dollar a barrel oil, and we will never see that again.

They are quite good at piquing your interest.

If you had the Swine Flu vaccine in 1976

You may have some immunity to the current H1N1 Swine Flu.

Term of the day: EROEI

Energy Return On Energy Invested

1859
1 unit of energy invested returns 1,000,000 units of energy (wells were shallow and were gushers)

1950
1 unit of energy invested returns 100 units of energy

2010
1 unit of energy invested returns 15 units of energy

Clearly, when 1 unit of energy must be invested to return 1 unit of energy, it no longer makes sense to try to extract the energy.

Unfortunately, we may run into problems even sooner: when 1 unit of energy invested returns only 8 units of energy. We are almost there.


So it is not a matter of whether or not the oil exists, but rather whether it can be extracted and delivered for a reasonable price.

Rush says "There is 700 years of oil in the ground! There is no oil problem!"
Ayn Rand said, one can evade reality, but one cannot evade the consequences of evading reality.
I would say, "Everything seems simple to the simpleminded".

The crater Cabeus A1

NASA plans to crash a rocket into the Lunar crater Cabeus A1 on October 9.

The floor of the crater is in perpetual darkness, and so over the eons, some water ice may have condensed there.

The crash should shoot a plume up, and the plume will be examined to see if there is water ice.

If there is, this will be a huge discovery because it would mean we would not have to launch so much water from the Earth for a base on the Moon.

Parasite eats fish tongue and takes the place of the tongue

This is so strange, I thought it was a joke from Cracked or The Onion or something.

Where would the world be without the extraordinary growth in Russian oil supply this decade? Not in a good place... Russia’s near 50% oil production increase since the year 2000 did a lot of heavy lifting. And it’s concerning that this very fast growth rate has now topped out.

North American crude oil production (Canada + US + Mexico) saw, during the current decade, its highest levels in 2003 at an annual average of 11.358 Mb/day. The high month of production that year was in September, at 11.450 Mb/day. In that year, 2003, the average price of oil was 31.08. But by 2008, North American crude oil production had fallen to 10.338 Mb/day. Thus, as the price of oil went from 31.08 in 2003 to the 2008 average of 99.67, North American crude oil production lost over a million bbls a day.


Russia... has become the world's biggest exporter of oil.

Russia toppled Saudi Arabia from the number one spot. It is already the world's largest exporter of gas, and supplies around a third of the European Union's consumption.

The many missions NASA is running now

People think NASA spends a huge amount of money, but it is a drop in the bucket, and they think it only does the shuttle, but see how many missions are currently running... you never hear about them, but they are fascinating.
