Something To Try Sometime

Category: Chatter

Make echinacea tea, fairly strong.  Refrigerate it.  Get some 100% pomegranate juice.  Refrigerate that.  Wait until cold.  Mix together in 1:1 proportion.  Drink.  

There is no particular reason for this, other that simply to have the experience.

Scientists Turn to Politics

Category: Politics

There is an interesting article put out by Associated Press, authored by Seth Borenstein.  Mr. Bornstein suggests that scientists are increasingly expressing an interest in running for office.

The involvement of scientists in politics is not new.  Think of Ben Franklin.  But many have been involved from the sidelines.  Franklin, for example, did not hold an elected position until the end of his life.  (He was President of the Supreme Executive Council of Pennsylvania 1785-88.)

Peak Oil, Proton Therapy, and the Future of High-Tech Medicine

Category: Medicine

One thing about hospitals, is that they use an awful lot of electricity.  We already know about some of the challenges that will occur in health care in the post-peak-oil era; I wrote about that in October 2007.  

...Petroleum scarcity will affect the health system in at least 4 ways: through effects on medical supplies and equipment, transportation, energy generation, and food production...

One way this will affect medical care is that it will change the relative costs of certain kinds of care.  Everything will cost more, of course.  More interestingly, the costs for some things will rise much faster than for others.  For example, the cost for ICU care -- already staggeringly expensive -- will rise faster than less intensive kinds of care.  

I was thinking about this when I was reading up on .  Proton therapy is a kind of radiation treatment, usually used to kill tumors.  There are only a few proton therapy facilities in the world (five in the USA).  More are being planned, but it is controversial.  The reason they are controversial, is that devices used happen to be the most expensive medical devices on the planet.

In Which I Succumb To the Fisking Bug

Category: Politics

The urge to fisk is an omnipresent danger for all bloggers.  Usually I am strong.  Usually I resist.  But this essay on World Net Daily got my fisking neurons all in a twitter.  It's by David Kupelian, and it's a World Net Daily Exclusive!  (Because no one else would print it.)

Poisoning Ourselves

Category: Public Health

In the aftermath of the terrorist attacks of 9/11, it was noticed that there were cuts in the budget to the Environmental Protection Agency.  The rationale was that we needed to shift more funds to the global and perpetual war on terror.  

At the time, I said that "the terrorists" won't have to bother trying to poison us.  Our own companies would do it for them.

Yup.

TRIBUNE EXCLUSIVE: EPA's top Midwest regulator forced out
Mary Gade, based in Chicago, says Bush administration made her quit over Dow Chemical case

By Michael Hawthorne | Tribune reporter
7:31 PM CDT, May 1, 2008

The Bush administration forced its top environmental regulator in the Midwest to quit Thursday after months of internal bickering about dioxin contamination downstream from Dow Chemical's world headquarters in Michigan.

In an interview with the Tribune, Mary Gade said two top officials at the U.S. Environmental Protection Agency headquarters in Washington stripped her of her powers as regional administrator and told her to quit or be fired by June 1.

Gade said she had told the agency she would resign her position, based in Chicago.

Let Us Calculate!

Category: Armchair Musings

The Ubuntu craze is sweeping SciencBlogs: Aardvarchaeology, Scientific Indian, Greg Laden, Corpus Callosum, even PZ's kid.  

At SB, we strive for logic and precision.  Enough so, that we swoon over passages such as this one, from :

"The only way to rectify our reasonings is to make them as tangible as those of the Mathematicians, so that we can find our error at a glance, and when there are disputes among persons, we can simply say: Let us calculate [calculemus], without further ado, to see who is right." (The Art of Discovery 1685, W 51)

Even though Leibniz predated empiricism, scientific types are drawn to his love of logic.  Computer users, too, are fond of Leibniz: he invented the binary number system.  

Leibniz was a great thinker, as well as a great mathematician.  Scientists have long used the binary computers Leibniz made possible, to aid in their computations; however, they have not been able to use them to aid in their thinking.  Until now:

Wisdom Teeth

Category: Personal

Everyone's anatomy has little quirks.  One of mine, is the length of the roots of my wisdom teeth.  They go down halfway to Sulawesi.  

When I was in college, I had to have two of them extracted.  The oral surgeon told me they were "difficult extractions."  Magnanimous as he was, he gave me a prescription for Tylenol #3.  Which is what they give you when they want you to think you are getting something that will work, even though they know perfectly well that it is completely useless.

So I went back to the house where I was renting a room.  There was this strange guy there.  Things like that happen in college.  One of your housemates invites someone over, and they end up staying for days, or weeks, but too long in any event.

I was never sure exactly who was responsible for this visitation.  Then we got to talking and I told him my mouth hurt, and why.  He said something like "dude, just try some of this."  Reaches into a backpack and pulls out an enormous bag of dried leaves of cannabis sativa.  

I knew perfectly well that that would be useless, too.  Cannabis is not particularly effective for acute pain.  So I waved that off.

The guy hung around for a couple of weeks, stank up the place, eventually ran out of pot, and moved on.  I have no idea where he went.

What I did, rather than mess around with drugs, was to go down to my room, which was in the basement, and listen to Patti Smith, real loud.  I had a fairly new pair of Polk Audio Monitor Series 5 speakers.  Modest, but effective.

The basement room was somewhere that nobody else would live.  But because of that, it was only $100 a month.  There were books everywhere, which improved the acoustics.  

Listening to Patti Smith did not alleviate the pain at all.  What it did, was to make the experience more interesting.  

Unlike the opioids, which make everything dull.

Patti Smith is to the limbic system what Ikebana is to botany.  She takes raw emotion and shows it to you in a new way.  There always is an unsettled precision to the display.  

A composition by Johann Sebastian Bach has mathematical precision.  A composition by Patti Smith has passion precision.  It isn't digital, of course.  It is like she has a genlock for brain waves.

To those who haven't seen it yet, here is a link to Patti Smith's website.  Nicely done.  Check out, in particular, the ihavesomeinformationforyou link.  It's like a blog, but it is just a series of entries.  There's no RSS feed.  Can't have everything, I suppose.

Also you can listen to an acoustic performance she did in the Current studio, archived by Minnesota Public Radio.  If you haven't heard anything by her yet, you can cut your teeth on this one.  You'll find that the roots of her wisdom go pretty deep.

On the Psychopathology of Liberalism

Category: Politics

A while back, a guy named Lyle Rossiter wrote a book, The Liberal Mind: The Psychological Causes of Political Madness.  I haven't read the book, so this is one of those posts that is less than fully authoritative.  Perhaps someone who has read it can point out any errors I might have made.

The book was published by Free World Books, LLC, which is not exactly a marketing powerhouse.  In fact, as far as I can tell, it is the only book put out by that particular publisher.  So I am guessing that I won't get any corrections from people who read it, because hardly anyone even knows about it.  

Someone pointed it out to me, though, based upon a link to a post on 15 February, 2008, at World Net Daily.  I searched a bit and found some excerpts from the book.

Psychotherapy for Terminal Cancer Patients

Category: Psychiatry

“Doctors think, ‘Well, of course she’s depressed — she’s dying of breast cancer,’” he said.

I do see that kind of response sometimes, not just with regard to terminally ill patients.  The physician does not think the depression should be treated, because it is felt to be an expected response to the situation.

If I even show up in an emergency department with a gunshot wound in my abdomen, I sure hope the doc doesn't refuse to treat it, saying "of course he's bleeding to death, he's been shot in the spleen."

The fact is, some patients with terminal cancer do develop major depression.  But it is not inevitable.  It happens in only about 25% of such patients.  

Plus, the cause of the condition does not matter.  If the condition is present, and causes a problem, and the patient wants something done, then it should be treated.  An update to a Cochrane Review on the subject shows that psychotherapy can be an effective treatment for depression in terminally ill cancer patients.  Moreover, psychotherapy is comparable in effectiveness to antidepressant medication.

I saw a reference to this finding in a news release from the Center for the Advancement of Health.  When I went to the Cochrane site, there was a message saying "The Cochrane Library is being updated today with the latest issue. Please note that you may experience difficulties viewing articles or performing searches..."  I was not able to find the actual report; only the abstract for the study protocol was available.

Still, the bottom-line conclusion is what is important.  

In the review, treatment effects for this group of patients were only slightly less than those found in clinical trials of antidepressant medications in people treated outside of cancer centers. “The effects are almost comparable to those obtained in antidepressant pharmacotherapy studies in general psychiatry settings,” Akechi said.

“It’s a clinically meaningful difference,” said David Spiegel, associate chair of psychiatry and behavioral sciences at Stanford University School of Medicine. “The key finding is that psychotherapy for depression for gravely ill cancer patients works.”

Spiegel, an expert on therapy in cancer patients, was not involved in the Cochrane review, although he was the lead investigator on one included study of this therapy.

Dr. Spiegel may lack objectivity on the matter.  But the Cochrane review process is designed carefully to eliminate as much bias as possible.  The conclusions of such reviews generally are held to be valid.  If something does not work, or if the evidence is insufficient to warrant a conclusion, they will say so.

Roundup-Resistant Weeds

Category: Bioethics

Here at ScienceBlogs, we've regularly posted about the thorny issue of antibiotic overuse, and the subsequent antibiotic resistance.  This is a good example of evolution in action; it's also a good reason why we need to study and understand evolution.  

But antibiotic resistance is not the only such example.  The same principle applies to herbicides and weeds.

Naturally, a good example comes to us courtesy of , the company that everyone loves to hate.  (There is even a movie now, The World According to Monsanto.  It's on Google video, here.)

You see, Monsanto has made a lot of money by engineering crops that are resistant to their most popular herbicide, ® (). The idea is that you can plant these crops, then bathe the field with Roundup.  The herbicide kills the weeds, but the crops are unaffected.

Any biology sophomore could tell you, that sooner or later, you will get Roundup-resistant weeds.

Now it has been documented.  Roundup was first used in 1976.  In 1996, Monsanto introduced Roundup-ready soybeans.  No Roundup-resistant weeds were detected before the widespread use of the resistant crops.  Even then, it took a while.  But now...

Tech Tip #6

Category: Environment

Forget to water your tomato plants?  Try using ollas (pronounced oy-ya).   is Spanish for pot, as in clay pot.  

What you do is to get unglazed clay pots, bury them near the plants, and put water in them.  The water leaks out very slowly, because the unglazed clay is permeable.  This creates a water plume underground.  

olla.jpg

What you see here are ollas, each made from two unglazed clay pots.  These pots cost $1.03 at K-Mart,on sale.  Two are bonded together using caulk.  I used caulk that is intended for kitchen counters, figuring it would be relatively nontoxic.  One hole is filled in; the other is left open.  The ollas are buried such that the hole peeks out.

The photo illustrates:

1) on the left: a buried olla with a matching clay cover.  The cover is intended to be used as a tray to set the pot on, but here, it is used to cover the hole.  You don't want to breed mosquitoes and propagate West Nile virus, after all.  

2) middle, lower-left: one olla with the open hole on top.

3) middle, upper-right: one olla with the occluded hole showing.

4) one of the covers laying on the ground.

5) a buried olla, with the opening showing.  

6) various tomato plants.

7) soaker hose.

Some people connect the ollas to a drip irrigation system.  This is done by getting corks with holes in them, and threading tubing from the irrigation system emitters into the corks.  

The ollas help to conserve water.  Perhaps more importantly, they help keep the plants alive.

Ruthlessness Gene "Discovered"

Category: Armchair Musings

I wasn't sure whether to put the quotes around "Ruthlessness Gene," or "Discovered."  I suppose I could have just left them out entirely, but I have this urge to spice things up a bit with punctuation marks.  Don't blame me...it's genetic.

Now, there is yet another correlation between a snippet of DNA, and a behavioral trait:


'Ruthlessness gene' discovered
Dictatorial behaviour may be partly genetic, study suggests.
Published online 4 April 2008 | Nature | doi:10.1038/news.2008.738
Michael Hopkin

Selfish dictators may owe their behaviour partly to their genes, according to a study that claims to have found a genetic link to ruthlessness. The study might help to explain the money-grabbing tendencies of those with a Machiavellian streak — from national dictators down to 'little Hitlers' found in workplaces the world over.

Researchers at the Hebrew University in Jerusalem found a link between a gene called AVPR1a and ruthless behaviour in an economic exercise called the 'Dictator Game'...

The gene under study, AVPR1a, codes for vasopressin receptors (specifically, arginine vasopressin 1a receptors).  Vasopressin does more that one thing.  One thing is does in some creatures, in some circumstances, is to promote prosocial behaviors.

I suspect most readers here will know enough to refrain from reading too much into this.

Photo of World Record Breaker

Category: Photos of Interest

A new world record has been set:

xinsrc_222040505130193731755.jpg


The previous record for hanging spoons on a human face was 15.  Joe Allison "smashed" the record with 16.  He's only 16 years old.  He thinks that when his forehead is a little bigger, he'll be able to do 17.
