Toyota Prius is Destroying the World

TK Kenyon, your intrepid scientist for non-majors, is not surprised to tell you that if you're thinking about buying a Toyota Prius because you think it will help the environment or halt global warming, STOP!
Because a Prius guzzles the equivalent of 1000 gallons of gas in its manufacture (because its Ni batteries are very energy-consuming to make), you have to save 1000 gallons of gas to break even on the "carbon expense" of its manufacture.
A Prius supposedly gets about 45 mpg, but that number is greatly disputed and more like 38 mpg.
Most cars get 30 mpg, so you're saving 8 mpg. At 10,000 miles per year, you save 70 gallons of gas with a Prius than if you drive your old car. "Paying off" the carbon debt to manufacture the Prius would thus take 14 years, 3 1/2 months to break even.
If you accept Toyota's vastly fudged MPG figures, a Prius burns 222 gallons per year, versus your old car's 333 gallons per year, to go 10,000 miles. At that difference of 111 gallons per year, it will take 9 years to break even on the carbon debt.
So, to save the planet, keep your old guzzler. You've already paid off the carbon debt of its manufacture; plus, junking it will fill up a landfill and create solid waste pollution.
Reduce, reuse, and recycle. You can't shop your way to environmentalism.

AIDS Vaccine: Should We Stop Looking?

A vaccine for HIV will certainly be based on a revolutionary idea.
The Problem
One of the major problems with HIV-vaccine research is that CD4+ cells like monocytes and macrophage express an IgG Fc receptor. Thus, any antibody that sticks to HIV is internalized via the FcR into the CD4+ WBC, and thus the WBC are infected by the tagalong HIV. Even antibodies that are "neutralizing" in a Petri dish increase infectivity.
Thus, I was not surprised when the recent Merck HIV vaccine study went terribly, horribly awry, actually increasing the likelihood of infection and leading to earlier death in vaccinated individuals.
No Solution?
Any antibody-stimulating vaccine will have this problem, assuming an IgG response. Passive immunization with F(ab') fragments might meet with a better result.
Should We Stop?
Seth Berkley, president of the International AIDS Vaccine Initiative, said in The Independent's survey: “Most people’s immune systems hold HIV in check for years before they develop AIDS. A small number of HIV-infected people seem never to develop the disease. There are also documented cases of individuals who have been repeatedly exposed to HIV, but have not become infected. If scientists can work out the type of immune responses that protect these individuals, it might provide vital clues about how to create a vaccine.”
The above data that Berkley notes is indeed reason for hope. However, a traditional vaccine will not evoke the anomalous immune responses that are so rarely observed.

NPR Interview of Kristen Byrnes, Global Warming Denier
Personally, I’m not sold on the whole idea of global warming, man-made or not. I used to be. I was upset by the enormous amounts of CO2 that we humans were venting into the atmosphere, just like we exhaust raw sewage into our oceans, etc., etc., etc. And, you know, it seemed warmer, discounting that horrendous Iowa winter of 1995 when temps hit -40F and the Iowa River froze over. You can eliminate outliers in your data, as long as you can account for them, or at least make a nice statistical argument for ignoring them. It seemed that the consensus of the scientific community is that man-made global warming is a threat, and I generally go along with scientific consensus unless there’s a valid reason to doubt, and it had better be a good one. I don’t like the contrarian position.
I do, however, like data. Hard data. Preferably raw, pre-crunched data.
Here’s what changed my mind on global warming: I read that horrible anti-GW novel by Michael Crichton, which so sticks in my mind that I can’t recall the title, and I thought that his novel was so badly written that surely its conclusions can be tossed aside with great force. Crichton is both a horrid novelist and merely an MD.
(Yes, I am arrogant to snark so widely. I hold a fiction MFA from Iowa, where I received many prizes, and have published two well-received novels. During my PhD work in microbiology, I taught medical students in a Midwestern medical school. They’re great at memorizing things but, let’s face it, medical school does not reward original thought nor critical thinking. Their exams are multiple-guess. So, I’m snarky and arrogant. Crichton has loads more money than I have and a huge house on Kauai. He can take the shot.)
So, I set out on my own course of study at UGoog. I expected to quickly dismiss Crichton’s objections with data and confirm the majority opinion. It seems like an overwhelming opinion. I figured it would take an hour.
Here’s what I found: the global warming data is terrible. The methods that collected the data that produced the scary graph that we’ve all seen (where temperature spikes up in the 1970’s) are beyond shaky. It’s really bad science.I read the whole UN report, and the data that is cited in the prologue, which everyone reads, is a minor part of the whole report. Only surface temps, and only those in major urban areas, are going up. Atmospheric temperatures are not. This is to be expected by the “heat island” effect, where asphalt retains more heat than soil and re-radiates this heat at night.
Personally, I’m on the fence. The data behind GW, whether man-made or not, sucks.
Here’s the problem: whenever you say that the data sucks, people jump on you like you insulted Jesus. They label you a “denialist” and, rather than debate the data, accuse you of wanting to rape the planet.
The global warming debate has moved from the arena of science, where one is free to debate data, methods, and conclusions, and into the area of religion, where one must adhere to dogma or else risk retribution.
That’s a huge problem.
When I published a short blog post about this (http://science4non-majors.blogspot.com/2007/11/hoax-of-global-warming-john-coleman.html ), I got hate mail. Not refute mail. Not argue mail. Hate mail.
Even though my blog post encouraged recycling and conservation, people accused me of trying to destroy the planet.
The debate about global warming must return to being a debate, not a tirade, not a crusade, and not a sermon.

Science Debate 2008

Please join and donate to this important cause. The democratic candidates have had a debate about their religious views. Surely, we deserve to know, in detail, what the plans of the candidates are for the scientific community, funding, and regulation.
John F. Kennedy dared us to dream of the moon. Our next president should inspire us, too.

Race-Specific Cancer Gene (Sort Of)
Using population genetics methods, scientists have found an allele (a form of a gene, due to mutation) that increases the odds for colon cancer by 10% if a person is of European ancestry (specifically Scottish ancestry) but not Japanese ancestry. Sunday, March 30, 2008

Science and Religion: The Missing Link
However, the study of science introduces people to ideas that are at odds with what religious organizations promulgate as true. This occurs most often when religion intrudes into the domain of science and not vice versa. When religion states that it has the answers to scientific questions, such as when the Bible states that the Earth is flat (All quotes, KJV: Daniel 4:10-11, Matthew 4:8) and immobile (Examples: I Chronicles 16:30, Psalm 93:1,) science disproves these hypotheses by definitively showing that the Earth is neither flat nor immobile.
Thus, science contradicts many edicts of religion when religion ventures out of its territory.
Science truly undermines religious faith, however, because it teaches people to think. Science teaches people to search for testable, real-world answers to problems and questions rather than rely on superstition, magical thinking, or laziness.
When asked, "Why is the sky blue?" a person of faith can only answer that God decrees it or formulate an inaccurate scientific answer. A person with some science background understands water vapor in the air refracts incoming sunlight toward the blue end of the visible light spectrum. Scientific endeavors, such as rockets and telescopes, have shown that there is no solid firmament above the Earth, as the Bible states.
When asked, "Why did I get sick?" a person of faith can only answer that God willed it, while a microbiologist could isolate the bacteria or virus that caused the infection and provide antibiotics or antivirals to eliminate the infection.
At a magic show, a person who relies on faith to explain the world can only marvel at the wonders. A person with a scientific background notes the smoke and mirrors and the rabbit under the podium, noting that the hat must have a removable panel.
When confronted with horrors in the world, a person of faith can only say that God willed it, perhaps to give Christians something to do. They might pray for God to provide food for the starving. A scientist, however, creates fertilizers, dams, or new strains of drought-resistant crops.
Science teaches people to think of logical, physical causes for events. This makes people less gullible.
By making people less gullible and intellectually lazy, yes indeed, science undermines religious faith.

Genetic Link to Autoimmune Diseases Type 1 Diabetes and Sjogren's: Hox11 gene
http://www.nature.com/icb/journal/vaop/ncurrent/full/icb20086a.html
Also important, it links the hearing loss often seen in Type 1 diabetes directly to the Hox11 gene malfunction, not the later autoimmune attack.
This paper suggests that treatment of Hox11 deficiency in people with mutations could prevent Type 1 diabetes, Sjorgren's syndrome, and hearing loss.

Instant Nanotech Test for Mad Cow Prions
Tuesday, March 25, 2008

Wellcome has awarded their prizes for best scientific images of the year, and they are pretty.
This micrograph, taken with a laser scanning confocal microscope (see post below,) is a picture of colon cancer cells. The fluors used are not labelled, but I shall make some educated guesses.
Blue here is a nuclear stain, meaning that it stains DNA in the nucleus of the cell, such as DAPI or BOBO.
The green fluor is a cytoskeleton stain. The cytoskeleton component stained here appears to be filamentous actin, because I see some stress fibers through the cells. The stain is probably phalloidin (a toxin from death cap mushrooms) conjugated to a fluor.
The red color is more ambiguous. It seems to colocalize with the cytoskeleton in some cells (red + green = yellow) but is more diffused and cytoplasmic in others. Could be an actin binding-protein or another component of the cytoskeleton.

The core in the middle is the RNA chromosome and associated core proteins. The blue half-shell is the viral capsid. The yellow proteins are the ride-along gooey things called the tegument.

Lunge:
First, PZ Myers, noted and eminent science blogger and professor, was not admitted to a pre-screening of the film Expelled!, an ID drive-by documentary on evolution, and blogged about how he was thrown out at the whim of the producers. (Previous post: here.)
Myers's guest, Richard Dawkins, was admitted without fuss (as the producers probably did not recognize him, and when asked to show identification, he produced his British passport under his legal name, "Clinton Richard Dawkins.")
It must be noted that both Myers and Dawkins appear in the film Expelled!, for which they were interviewed under false pretenses, and the piecemeal editing of their interviews was journalistically unethical.
Parry:
After some brouhaha, Matthew Nesbit, a professor of communications, blogged:
"As long as Dawkins and PZ continue to be the representative voices from the pro-science side in this debate, it is really bad for those of us who care about promoting public trust in science and science education. Dawkins and PZ need to lay low as Expelled hits theaters. Let others play the role of communicator, most importantly the National Center for Science Education, AAAS, the National Academies or scientists such as Francis Ayala or Ken Miller. When called up by reporters or asked to comment, Dawkins and PZ should refer journalists to these organizations and individuals."
At the risk here of being arch, isn't "communications" what people who flunk out of business major in?
More to the point, Nesbit is utterly wrong. He compares the evolution vs. ID debate to politics, comparing Myers and Dawkins to, "Samantha Power, Geraldine Ferraro and so many other political operatives who through misstatements and polarizing rhetoric have ended up being liabilities to the causes and campaigns that they support."
This comparison is a fallacy.
Science is not politics, which is convincing a majority of the people that your political theory is the correct one to vote for on the day of elections in the majority of the voting districts. Politics seeks to create consensus.
Science is the truth. Myers and Dawkins should not be compared to Power and Ferraro, but to Galileo, Darwin, and Copernicus. No matter what the ID guys believe, they're wrong. Convincing more people that creationism is valid will not make it less wrong. Religionists' balking at evolution is just another example of irrational, superstitious flailing.
Nesbit's whole philosophy, "Framing Science," in which mostly non-scientists try to reconcile science with religion, which are several systems of contradictory and unsubstantiated beliefs, is a waste of time.
Yes, we should try to break it gently to religionists that they've been utterly wrong all these years, but eventually, the obvious truth of science will prevail. It's only a matter of time, another scientific concept.
I admit, when I saw Nesbit's blog and its title, "Framing Science," I thought it was a provocative anti-science blog, like when the cops "frame" someone for a crime. Perhaps that wasn't the best moniker for their movement. You would think that a communications major might have thought of that.
Another non-scientist "framing" guy, Chris Mooney, blogged that the PZ Myers controversy is giving the film loads of free publicty, is thus counter-productive, and also suggested that Myers should refrain from more discussion.
Riposte:
Nesbit's post led PZ Myers to this sputtering reply, which is perhaps less eloquent than his usual posts but heartfelt, in which he said in part, "Fuck you very much, Matt. You know where you can stick your advice."
Again, scientists are not politicians, who strive to form consensus or convince voters, or religionists, who seek to silence the opposing viewpoint.
People should go see that film and laugh at it for the dreck it is. The public should understand that Dawkins and Myers were interviewed under false presenses (the film makers told them it was a documentary about science and education, not a religion drive-by of evolution,) and with shoddy journalistic ethics (including the old trick of setting the camera and the interviewer at 90 degrees to each other, and thus the subject looks back and forth between the camera and the interviewer, producing a "shify-eyed" effect that is associated with lying or unreliability.)
Scientists seek the truth, and when we find it, we tell other people the truth. If there are contrary opinions, we debate the evidence and logically decide whose model is more accurate.
That's the problem with non-scientists like Mooney and Nesbit. They're operating in the rhelm of opinion, not truth. They're seeking to sway people with propaganda, not evidence and logic. They're using the enemy's faulty weapons against the enemy, who designed them, have the blueprints, and know where the weak points are.
Evolution is model with huge amounts of scientific evidence backing it up.
Sure, all models are wrong, but some models are useful.
Evolution is a useful model. It explains the past and, contrary to what ID guys will tell you, it accurately predicts future results.
ID and creationism in general do not accurately predict future results, except perhaps that creationists lie to themselves and others and will continue to do so.
Mooney and Nesbit are in the wrong on this issue.
Myers and Dawkins should not shut up.
Scientists tell the truth. Politicians and religionists seek create consensus or to silence the opposition. Pandering to their illogical and ignorant views will only endow them with a false sense of superiority, to go along with their false view of the universe and their false beliefs.
To PZ Myers and Richard Dawkins: Once more into the breach!
