PictureExpression of Disgust
Some areas of research are glamorous, such as the stars, the genome, or dinosaurs. Some other areas of research are vital to our well-being, such as vaccines, heart disease, and cancer. Other areas of research are fun, such as puzzles and game theory. And the best thing about research in these areas is that you can talk about it during lunch, dinner, and cocktail parties!
 
However, some areas of research delve into subjects that most people would consider downright disgusting. But what are scientists to do if their pursuit of the scientific truth leads them to spend long hours in the office, the field, or the lab designing and carrying out experiments or analyses dealing with slimy icky things, body parts, tissue samples, or bodily fluids? In this post we are going to see why people consider some things disgusting, but first we are going to go over some examples of research into disgusting things that scientists have published.
​


Coincident Tick Infestations in the Nostrils of Wild Chimpanzees and a Human in Uganda by Hamer and coworkers, published in The American Journal of Tropical Medicine and Hygiene in 2013.
Here a scientist studying ticks in the nostrils of chimpanzees found that one of these arachnids had latched on to his own nose. He took it out, sequenced its DNA, and found out it may be a new species!
 
Buttock Augmentation: A Novel Alternative to a Lengthy Procedure by George Solomon, published in The American Journal of Cosmetic Surgery in 2016.
Who would not be interested in coming up with a better procedure to increase buttock size?
 
The effect of acute increase in urge to void on cognitive function in healthy adults by Lewis and coworkers, published in the journal Neurourology and Urodynamics in 2011.
In this research, scientists had people perform cognitive tasks while drinking fluid. The researchers found that the more you want to pee, the less well you perform in a cognitive task. Good to know!
 
Volatile components in defensive spray of the hooded skunk, Mephitis macroura by Wood and coworkers, published in the Journal of Chemical Ecology in 2002.
Here the researchers investigated all the chemical compounds present in the anal sack of a variety of skunk. This research stinks!
 
Experimental replication shows knives manufactured from frozen human feces do not work by Eran and coworkers, published in the Journal of Archaeological Science: Reports in 2019.
An old story in archeological circles stated that a man made a knife from his frozen feces to butcher an animal. The researcher here found out these knives do not work. So now you know what not to do when trying to butcher an animal.
 
The fate of the embedded virgin sand flea Tunga penetrans: Hypothesis, self-experimentation and photographic sequence by Thielecke and Feldmeier, published in the journal Travel Medicine and Infectious Disease in 2013.
In this article, a researcher found that a sand flea had burrowed under her skin. She allowed it to remain there and made observations that permitted her to gain insight into how sand fleas reproduce. Now, that’s dedication!
 
The effect of Having Christmas Dinner with In-Laws on Gut Microbiota composition by de Clercq and coworkers, published in the Human Microbiome Journal in 2019.
Yes, you read that right. These researchers investigated how having dinner with your in laws changes the bacterial composition of your intestinal contents.
 
Personal space invasions in the lavatory: suggestive evidence for arousal by Middlemist and coworkers, published in the Journal of Personality and Social Psychology in 1976.
Here researchers found that men who have other men peeing next to them take longer to begin peeing. I would just sing that song, “Don’t stand so close to me.”
 
Biomechanics of male erectile function by Daniel Udelson, published in the Journal of the Royal Society, Interface in 2007.
The author of this article studied the male organ and came up with complex mathematical equations that describe its buckling as well as blood flow through it. This guy is an expert.
 
Pressures produced when penguins pooh—calculations on avian defaecation by Meyer-Rochow and Gal published in the journal Polar Biology in 2003.

As it turns out, some researchers not only study disgusting things, but they also study why you find the things they study disgusting!
 
The observation was made a long time ago that those things that people find disgusting are related in various ways to infectious diseases. So, scientists have developed the hypothesis that the feeling of disgust in animals such as humans evolved to affect behavior in such a way as to reduce the risk of infection. This is the so called “parasite avoidance theory”.
 
A group of researchers tested the theory by performing an experiment where they presented several disgusting scenarios in writing to a total of more than 2,600 participants in a study. These scenarios ranged from watching people pick their nose, spotting an unflushed toilet, or seeing pus come out of a genital sore, to accidentally using someone else’s deodorant, eating onion flavored ice cream, or watching a fly crawl across the face of a sleeping friend. The participants were asked to rate each scenario in a scale from 0 (no disgust) to 100 (extreme disgust). Using statistics, the scientists found that the responses of the participants could be categorized into six factors: avoidance of skin lesions, spoiled foods, animal vectors, promiscuous sexual practices, and individuals with poor hygiene or atypical appearance. This suggests that human beings have an instinctive “pathogen detection system” that leads them to avoid people, practices, and objects associated with infectious disease.
 
But research into disgust is not merely an academic endeavor. Disgust plays an important role in anxiety and phobias, and disgust is an emotion that can often affect our judgement in subtle ways. For instance, in another study researchers asked people to make moral judgments in environments where they were exposed to disgusting stimuli such as a bad smell. They found that people in the disgusting environments tended to make harsher moral judgments. This awareness of the effects of disgust in human psychology has been applied to promote the avoidance of behaviors by people that can lead to spread of disease. Unfortunately, it can also be misapplied to fan prejudice and stigmatize individuals or entire groups of people. For example, studies have revealed that people that are more prone to being disgusted have a greater intuitive disapproval of gay people, and in the past (it is more subtle nowadays) much anti-gay propaganda contained associations with disgusting images and statements.

The Saga of Hydroxychloroquine for COVID-19 Has Come to an End

Picture

I have written extensively on hydroxychloroquine (HQ) in my blog. Now that the interest of society has shifted towards the COVID-19 vaccines, it’s time to do a recap of the issues I addressed related to HQ and provide a final update.
 
4/25/2020
President Trump advocated HQ and one his advisers criticized Dr. Fauci for questioning its effectiveness. The French doctor Didier Raoult claimed a 99.3% success rate in treating COVID-19 patients with HQ, and accounts of patients treated with HQ experiencing dramatic recoveries (Lazarus-like coming back from the dead effects) were appearing in the news. In my post, I warmed against accepting these isolated “dramatic effects” reports as a measure of a drug effectiveness, stated that the only measure of a drug’s effectiveness is clinical trials, and explained why.
​

6/19/2020
I addressed the claim made by some doctors that HQ is 100% effective against COVID-19, and I explained not only why it is highly unlikely, but also that this is a regular claim made by charlatans. I also explain that the best clinical trials conducted so far had not found evidence that HQ worked.
 
7/3/2020
I debunked the misinformation that Dr. Fauci is aligned with powerful pharmaceutical interests to hamper the adoption of HQ as a life saving drug, and that Dr. Fauci already knew HQ worked more than 15 years ago. I also addressed the issue of the articles claiming that HQ did not work and was harmful. I argued that the fact that these articles were published in medical journals and then retracted is not a conspiracy but rather indicate that science worked the way it should. I also debunked the notion that countries that had embraced the use of HQ were doing better.

7/25/2020
I decried the politization of HQ and the notion that it is “the president’s drug”, and I outlined the evidence at the time against HQ which indicated it’s not effective against COVID-19.
 
8/8/2020
I debunked in more detail the conspiracy that Fauci knew about HQ being effective, and I proceeded to explain a bold hypothesis that explains why HQ alone does not work against COVID-19.
 
8/20/2020
I debunked the notions that high doses of HQ were used in some clinical trials to make HQ fail, or that pharmaceutical companies want to eliminate HQ because it’s a cheap alternative to their expensive drugs. Since some HQ proponents were then arguing that HQ only works with zinc (the zinc hypothesis), I pointed out that this contradicted their cheering of studies where HQ allegedly worked alone (which it shouldn’t have if it only works with zinc).
 
9/12/2020
I examined the difference between doctors and scientists and debunked the notions that “doctors know best” and that “we don’t need randomized trials”. I also described the important role of the scientific establishment in science.
 
9/18/2020
I explained why observational trials cannot provide the final evidence that HQ works, and I pointed out that even the authors of the studies that the pro-HQ folk cite in favor of HQ state that randomized trials are needed.
 
10/16/2020
Despite the evidence which indicated that HQ did not work alone or with antibiotics, some HQ proponents still supported the hypothesis that HQ worked as long as you combined it with zinc. In this post I explained the evidence against HQ alone or with zinc. I also explained why it is important to remain objective and not fall in love with your hypotheses.
 
10/24/2020
In this final post, I readdressed the conspiracy theory that claimed that the clinical trials of HQ were designed to make it fail. I also examined the accusation that Dr. Fauci’s unwillingness to accept that HQ works was killing people.
 
Update
As I have mentioned before, to reach a conclusion regarding the activity of HQ on COVID-19 you need to focus on the studies that allocate patients to treatments at random (randomized studies). There are people that keep pushing the claim that HQ does work based on the total number of studies performed on the drug, which includes the observational (non-randomized) studies which are of lower quality because they are prone to bias. I searched a database for randomized studies of HQ and COVID-19, and only two of the studies I found were positive for the drug (1, 2), whereas 25 other studies were negative (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25).
 
However, whether HQ works or not cannot be established merely by counting the number of pro and con studies. Even among randomized studies, some studies are of lower quality than others. One or two high-quality studies can trump many low-quality studies. In order to evaluate the merits of studies in addressing whether HQ works for COVID-19, scientists perform analyses (studies of studies) where they assess the quality and relevance of the studies. Throughout the COVID-19 pandemic several of these analyses have been performed. I searched the database for these analyses and I found 20 of them, all negative for HQ (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20).
 
The conclusion is inescapable, hydroxychloroquine DOES NOT work for COVID-19. Period, end of the discussion. The breathtaking number of studies conducted on this drug is a testament to its politicization. The sheer amount of manpower and resources devoted to testing HQ was unjustified when a handful of studies would have sufficed. The attacks and lies hurdled against scientists including Dr. Fauci because they refused to accept that HQ works based on the available data was unethical.
 
From Mr. Trump who unwisely promoted the drug to individuals such as the epidemiologist Harvey Risch and Dr. Vladimir Zelenko or groups such as the Front-Line Doctors who all claimed the drug worked even when the best evidence indicated otherwise, this saga has been a lesson on what people should not do with science and in science. Unfortunately, these people have not learned their lesson and still claim to have been right all along.
 
Such is the complexity of the human mind.

How can you even do science in this environment?

PictureCOVID-19 Vaccine
As I have written several times, science is a process that involves a lot of back and forth. Scientists have different opinions and exchange arguments. They adopt positions based on the available evidence and change their mind when new evidence comes along. As is expected, this process is ongoing for the COVID-19 vaccines. These vaccines have been found to be safe and effective in clinical trials and in studies conducted afterwards in real-world situations. But all vaccines, as everything, do have small risks. For example, the COVID-19 vaccines can cause an anaphylactic reaction in individuals prone to severe allergies, and this is recognized in vaccination decisions and procedures.
 
Because scientists want vaccines to be as safe as possible, there is an effort to identify other rare side effects of vaccines as well as figuring out how the COVID-19 virus works so more effective and safer vaccines can be made. Most COVID-19 vaccines rely on making the cells at the site of injection produce the viral spike protein, which is the protein that allows the virus to get into the cells and infect them. These spike proteins are anchored to the surface of the cells expressing them and trigger the immune response. Therefore, this protein is an object of ongoing research.

Several articles have been published in the scientific literature regarding this protein. In one article, researchers found that the spike protein alone in the absence of the rest of the virus can damage the wall of blood vessels (the endothelium). In a another article researchers found that the spike protein alone or its subunits (the spike protein is made up of two subunits) can disrupt the barrier that protects the brain from blood borne substances (the blood brain barrier). These findings, although preliminary, are important in that COVID-19 displays many symptoms involving the circulatory system and indicate that the spike protein alone could be responsible for them.
 
The issue we are discussing today arises from another article where researchers were able to measure the spike protein in the circulation of patients who had received the COVID-19 vaccine. A Canadian immunologist, Dr. Byram Bridle, saw the above data and (apparently without consulting with colleagues or the authors of the articles) started claiming that we have made a mistake with the COVID-19 vaccines. He unwisely gave interviews where he claimed that the vaccines make our cells produce the spike protein which is a toxin that leaks to the circulation where it can cause damage in some people. Needless to say the antivaxxer social media pages and websites lit up like a Christmas tree and unleashed upon the internet a torrent of posts and memes proclaiming how unsafe the COVID-19 vaccines are, demanding that vaccinations stop, and bragging about how they had been right all along.
 
I am not going to debunk this in detail, as others have done a very good job of that, but here is the gist of the argument. The method used by the researchers that detected the vaccine spike protein in the blood was 100-1000 times more sensitive than regular methods. The amount of protein they measured is basically the background that you would get from a very, very small fraction of the protein making into the circulation because of, for example, cells dying. These levels are tens of thousands of times lower than the spike protein concentrations reported to be detrimental in the other articles. Additionally, the spike protein generated by the vaccine is different from the spike protein from the virus as it has been engineered to be safer. Many scientists including colleagues of Dr. Bridle and even the authors of the papers claim that he is overinterpreting the data. Finally, if indeed the spike protein alone turns out to be responsible for a sizable portion of the COVID-19 pathology, then that is excellent news because the antibodies produced by the vaccine (unlike natural immunity) are all against the spike protein, so they will likely neutralize this toxicity too.
 
Now let me get to the question I formulated in the title of this post. How can you do science in this environment? Scientific research is no cakewalk. There is a lot of frustration and anxiety involved. There are many defeats and few victories. But finally, when scientists find something worth publishing, how do you think they feel when their results are misinterpreted? Every scientist in the COVID-19 field who deals with the demands of research and the toll it takes on their lives must now consider the possibility that the results of their investigations will be splashed in misleading memes all over the internet by the antivaxxer crowd. This means that they will have to devote some of their limited time to dispelling these ideas by doing interviews, writing articles, or answering e-mails from scores of people.
 
But the worst part is that if scientists find something that may be negative about the COVID-19 vaccine, they may be inclined not to publish it just to avoid being in the center of the media hurricane that will surely form around them. And this is terrible, because we need every piece of information so we can have a more complete picture of the safety and efficacy of the vaccines in order to improve them.
 
Science thrives on an open debate among scientists. In the old days this debate, which involves highly technical information with a lot of detail and nuance, took place mostly within the scientific community. Today the public can gain access to this debate by several means. Although this is a positive development, the preliminary data and tentative ideas that scientists generate as part of this debate, are being misrepresented by many people, sometimes out of ignorance, but most of the time as part of an agenda to generate viral stories to cause confusion and sow doubt.
 
And scientists are stuck in the middle of this.

What Can Neurological Conditions and Diseases Tell Us About the Mind?

0 Comments

Read Now
 
Picture
Scientists know that one important way to gain insight into how the human mind works is by observing what happens when it experiences a disfunction. In this regard, scientists have documented some rare but remarkable neurological conditions and diseases.
 
The normal function of the brain may be altered as a result of a surgical procedure.
 
Split Brain
In the second half of the twentieth century, doctors carried out a radical surgery that severed the connections between the two hemispheres of the brain to treat uncurable seizures. While this procedure was effective at stopping the seizures, it would leave both brain hemispheres unable to share information and coordinate with each other. These split-brain patients have been objects of much research that has allowed scientists to gain insight into how the brain normally works.
 
In humans, the right hemisphere receives nerve inputs from and controls the left side of the body, whereas the left hemisphere does likewise with the right half. With regards to vision, the left hemisphere receives information about the right side of the visual field (it cannot see the left side) with the opposite happening with the right hemisphere. Using this information, scientists were able to relay questions to the subjects and make them perform tasks in such a way that they could discriminate between the responses and performance of the right and the left hemispheres, and what they found was amazing.
 
They discovered that the two hemispheres often displayed separate personalities and held different beliefs with one split brain patient famously answering the question “Do you believe in God?” with a “Yes” by one hemisphere and a “No” by the other. They also found that the communication between both hemispheres was required for exercising normal moral judgement in fast answers to specific questions.
 
The normal function of the brain may also be altered as a result of a disease or a traumatic event.
 
Cotard's Syndrome
This one is also called, “The Walking Corpse Syndrome” because the individuals afflicted by it develop what are called nihilistic delusions in which they perceive themselves, or some of their body parts, to be dead, dying, or to not exist at all. People with this affliction will reduce food intake or stop eating because they have no use for this activity as they believe themselves to be dead after all. Some patients will spend an inordinate amount of time in cemeteries. Cotard’s Syndrome is often associated with other conditions ranging from severe depression to neurological conditions and diseases.
 
Alien Hand Syndrome
In this curious disease, one of the hands of a person will start moving on its own without the person being able to control it. The hand will perform purposeful tasks sometimes repeatedly, and may even antagonize things the other hand has just done such as buttoning a button. Alien Hand Syndrome is associated with conditions that cause trauma to the brain and neurodegenerative diseases.
 
Dissociative Identity Disorder
This disorder, which in the past was called Multiple Personality Disorder, is a situation where the identity of a person is split among at least two separate identities that take control over the individual. Each identity may have their own name, sex, race, and psychological and physical characteristics. Dissociative Identity Disorder is associated with the suffering of psychological trauma specially during childhood.
 
Apotemnophilia
People affected with Apotemnophilia have an overwhelming desire to amputate their limbs, with some expressing a wish to be paralyzed. Some of the afflicted individuals perform the amputations themselves or ask their friends, relatives, and health practitioners to help them with the process. Although scientists still don’t know what causes the condition, a possible explanation is a faulty representation of the limbs in the areas of the brain that deal with self-recognition of body structures.
 
Boanthropy, Clinical Lycanthropy, and Clinical Zoanthropy
Boanthropy is a condition where the affected persons believe themselves to be a cow or ox. They will actually go over to pastures, get down on all fours, and eat grass. Clinical Lycanthropy involves people who think they are turning into werewolves. These people see their bodies covered with hair and their fingernails and teeth elongated. These two conditions are cases of the broader disease called Zoanthropy where people believe themselves to have turned into various animals. Some of these conditions are associated with diagnosed mental diseases such as schizophrenia, bipolar disorder, or severe depression.
 
So, what does the information I presented above reveal about ourselves and our brains?
 
Most people accept that the brain plays a key role in movement. Individuals who break their spinal columns may be unable to move their limbs. I have posted a video of the time I had Bell’s Palsy where a malfunction in a nerve paralyzed half of my face. Similarly, most people accept the role that the brain plays in processes such as learning, perception, and memory, and there are many examples of accidents or diseases that have led to impairment of these processes.
 
Nevertheless, despite the acceptance of the role of the brain in determining the processes described above, many people believe the human mind is something special. These people believe that there is something else, whether you call it soul, spirit, essence, or any other such term, that is responsible for the most fundamental aspects of the human mind which they believe cannot just merely be produced by a bunch or nerve cells.
 
However, the pathologies or conditions I have listed in this post and others indicate to us the importance of the brain not just in determining obvious things like movement, learning, perception, and memory, but also in determining things that lie at the very core of our humanity such as who we are, how we see ourselves, and what we believe in. If a bunch of nerve cells can create movement, learning, perception, and memory, why can’t they also determine our very nature? Much in the same way that the intestines can create digestion, why can’t the brain create the mind?
 
Of course, science cannot say anything about the existence of a soul, essence, or spirit, but what we can say at this moment is that all the evidence we have so far indicates that everything that you are seems to be nothing more than the result of millions of nerve cells in your head communicating with each other in different patterns and at different times.
 
Boggles the mind, eh?

COVID-19 Origins: Conventional Thinking, Conspiratorial Thinking, Crazy Thinking, and Bat Crap Crazy Thinking

0 Comments

Read Now
 
Picture
I have often railed against conspiracy theories in my blog, but I want to make it clear that I make a distinction between conspiracies and conspiracy theories. There have been many verified conspiracies. The cigarette manufacturing companies conspired to hide the fact that cigarettes were harmful. The Nixon administration conspired to maintain its involvement in the wiretapping of the Democratic headquarters in the Watergate Building a secret. The Catholic Church conspired to hide child abuse by their priests. These conspiracies have been exposed and found to be true by detective work backed by internal documents and testimony from witnesses. Conspiracies do happen, and we must take claims of a conspiracy seriously, but only as long as they are backed by evidence. The argument that COVID-19 originated in a lab was originally branded a conspiracy theory, but evidence has emerged, and arguments have been made that have made it more plausible generating a debate within the scientific community. This debate is guided by what we can call “conventional thinking” following the terminology of the Conspiracy Theory Handbook by Stephan Lewandowsky and John Cook.
 
Conventional Thinking
Several scientists have argued that there is strong evidence that the COVID-19 virus, SARS-Cov-2, arose in the Wuhan Institute of Virology (WIV) and not in a natural manner. Although the details are highly technical, in a nutshell it is argued that there are some aspects of the SARS-COV-2 virus that are unusual as it contains sequences that make it highly contagious for humans. It is also argued that analysis of viral genomes in bats and other animals make it unlikely that the Covid-19 virus arose naturally. Unlike previous coronavirus disease outbreaks, no viruses bearing a close relationship to the SARS-Cov-2 virus have been found around the Wuhan area, and the WIV had samples of large number of bat coronaviruses that they had gathered in trips to several caves a thousand miles away in another Chinese province. It is claimed that the WIV was carrying out gain of function research, which is research performed to make weak viruses more infectious, and that a grant from the NIH may have funded some of this gain of function research. Recently US intelligence has confirmed that some researchers from the WIV were admitted to a hospital with flu-like symptoms before the Covid-19 pandemic started. It is also known that researchers at the WIV were not following safety protocols when collecting the viruses. Thus, there is the possibility that the Covid-19 virus could have been present or even created at the WIV and released accidentally.
 
The critics counter that careful analysis of aspects of the virus’ genetic sequence and makeup compared to other preexisting coronaviruses still leaves open the possibility that the COVID-19 virus arose naturally. They also argue that it is questionable whether the Covid-19 virus shows signs of manipulation or optimization to infect humans as per the most current genetic techniques used in the field of virology. They further point out that some people that have entered caves containing populations of bats have become sick with a Covid-like disease, suggesting that these viruses can infect people directly without need for genetic modification. Finally, they argue that the production of vaccines and drugs against Covid-19 benefited from research at the WIV. With regards to the gain of function funding claims, officials such as Dr. Fauci and the NIH director Dr. Francis Collins deny that the grant money that reached the WIV funded any such research.
 
The above debate is what you get when scientists and other individuals with competing ideas are involved in an exchange regarding complex technical issues. The process of conventional thinking involves skepticism, evaluation of evidence, and coherence. Conventional thinking is not perfect, as it can be distorted by politics, polarization, and emotions, but it is the best method we have at our disposal to generate evidence-based answers to questions. The opposite to conventional thinking is what we will call conspiratorial thinking also following the terminology of the Conspiracy Theory Handbook.
 
Conspiratorial Thinking
There are several conspiracy theories regarding the origin of the COVID-19 virus. In general, many of them start with the information I have alluded to above and make the leap to argue not only the “certainty” that the virus was produced at the WIV as a bioweapon with NIH funding, but that the Chinese government released the virus on purpose with the goal of bringing down Donald Trump’s presidency or somehow gaining some global advantage over other countries. While conventional thinking and conspiratorial thinking both rely heavily on evidence, conspiratorial thinking involves overriding suspicion, over-interpretation of the evidence, and often results in contradiction. When properly carried out, conventional thinking uses evidence to find the truth, while conspiratorial thinking often uses evidence to justify a prejudice.
 
Apart from the levels of “conventional thinking” and “conspiratorial thinking” from the Conspiracy Theory Handbook, I also want to suggest two additional levels that lie below it.
 
Crazy Thinking
In this level, it is argued not only that China developed and released the virus, but that it did so with the support of the deep state within the US government to not only bring down Trump but to control and track the behavior of people through mask wearing and other measures including the implantation of a microchip using vaccines in coordination with Bill Gates and his foundation. In these claims, Dr. Fauci and other government figures not only knowingly funded the development of COVID-19 by China but also coordinated with pharmaceutical companies to enrich themselves and oppose cheaper effective therapeutic alternatives like hydroxychloroquine. While conspiratorial thinking makes the mistake of overinterpreting evidence or using it in a selective way, at the crazy level people make use of evidence only in the most cursory of ways to lay the foundation for an edifice that they erect based on innuendo, hearsay, rumors, ignorance, fear, bigotry, misinformation, and disinformation. But believe it or not, things can get worse.
 
Bat Crap Crazy Thinking
This is the ultimate level of human folly. Here is where you find QAnon, tin foil hatters, flat Earthers and other such fringe. The individuals in this level are so divorced from reality that their claims often run afoul of mainstream crazy. With regards to COVID-19 origins, they make assertions such as that the disease is not produced by a virus but rather by 5G wireless networks, or that it is not a disease at all but a cover up for sex trafficking by a cabal of deep state satanic pedophiles who torture children and drink their blood. They make claims that COVID-19 vaccines are lethal, that the vaccines themselves can cause COVID-19, or that they change people’s DNA. They also argue that the pandemic is a sham, which they call “shamdemic”.
 
The effort to understand the origins of COVID-19 is ongoing, but it is far from perfect. Human passions and folly at several levels may stand in the way of progress towards this goal, but hopefully sane people of goodwill guided by science will get us there.

Apparent Creationist Vandalism in Fall Creek Falls State Park

0 Comments

Read Now
 
I recently went to Fall Creek Falls State Park in Tennessee and visited several of its waterfalls including the magnificent Fall Creek Falls, which is the tallest free-falling waterfall in the Eastern United States (see below).
​

When I visit a place such as Fall Creek Falls, I like to enjoy the immediate beauty of the area which I can perceive through my eyes, but I also like to place what I see around me in the context of the scientific knowledge we have about the place.

The park is part of a geological area in Tennessee that is called the Cumberland Plateau which rises about 1,000 feet over the Tennessee River Valley. Several of the limestone, dolomite, and shale rocks in the Cumberland Plateau started out as sediments deposited in a swallow sea 360-320 million years ago. And from 320 to 300 million years ago the erosion of the Blue Ridge Mountains, which once were as tall as the Rocky Mountains, also contributed sand and pebbles to the area. Over millions of years the sediments were compacted (lithified) into rocks and the whole area experienced an uplifting event which led to the creation of swift streams that carved out gorges in the plateau creating beautiful waterfalls such as Fall Creek Falls.

When I stand near Fall Creek Falls, I am standing in an area that hundreds of millions of years ago was a tropical sea. And when I look at some of the rocks under the waterfall, I am looking at sediments that came from the summits of mighty mountains. Isn’t that amazing? Doesn’t that knowledge increase our sense of wonder about the place? It does so for me, but my enjoyment was dampened a bit when I saw that some of the park signs had been vandalized in a particular way.
​


​Signs everywhere are often vandalized by individuals for different reasons, but I noticed that the sign next to Fall Creek Falls (as well as other signs in the park) had one word crossed out: the word “millions”. And in this particular sign, the word “thousands” had been scratched in below. Clearly the person defacing the sign had a problem with the sign alluding to geologic formations “millions of years old” feeling that the proper description should have been “thousands of years old”. Who would this person be and why would they choose to vandalize the sign in this way?
 
Although I have no definite proof, I presume that the individual(s) who vandalized this and other signs in the park believe in creationism. Other persons who have read these signs have arrived at the same conclusion.
 
Creationists are people who adhere to a literal interpretation of the Bible and believe in several things that are contrary to scientific evidence such as that the Earth is only 6,000 to 10,000 thousand years old, that there was a universal flood that covered much of the Earth, and that all living things were created at the same time, and therefore human beings coexisted with dinosaurs. In recent years, creationists have framed the refusal of mainstream science to accept their views while promoting the teaching of evolution in schools as an attack on religion and the imposition of atheism. This is not true, but I have dealt with creationists before in my blog, so I am not going to repeat myself in this post. However, I do want to address the issue behind the vandalism. How do we know the Earth is much older than 6,000 years? There are many ways to figure this out, but I will only talk about two of them here.
 
I have already mentioned in the Interesting Stuff section of my website that one of the methods scientists use to determine the age of rocks is radiometric dating. Radioactive elements decompose into other elements at fixed rates, and by measuring the proportion of both the parent and daughter elements in the rocks, scientists can find out when these rocks were formed. The results repeatedly obtained by many scientists using these techniques applied in many areas of the Earth is that the oldest rocks of our planet are billions of years old. This result has also been obtained when radiometric techniques were applied to meteorites and moon rocks. Creationists argue that radiometric techniques rely on false assumptions and have seized on mistakes made by some scientists to discredit these techniques. However, not only have creationist arguments been refuted, but many examples abound of rocks that have been carefully analyzed and found to be much older than creationist claims.
 
Another way to figure out that the Earth is much older than 6,000 to 10,00 years is using the science from plate tectonics. The continents of the Earth are sitting on top of areas of the Earth’s crust called plates that move over the Earth’s mantle very slowly. Some continents that were connected in the past, such as North America and Africa, have since moved away from each other, while India has crashed into Asia giving rise to the Himalayan Mountains. The rate of movement of these plates nowadays can be measured by GPS and it is in the order of 0.6 to 10 centimeters per year. If you calculate the thousands of miles that the continents must have travelled at these slow rates, you arrive at figures in the tens to hundreds of millions of years. Creationists claim (with no evidence) that plate movement was much faster in the past, but to pack all that movement of colossal landmasses into a span of a few thousand years would be impossible from a physical point of view.
 
The error in the creationist beliefs comes from using the Bible as a textbook of natural history, which it is not. To express this in a couple of sentences. The Bible is about how to go to heaven, not about how the heavens go. The Bible is about the rock of ages, not about the age of rocks. Creationists do a disservice not only to science but also to religion itself when using the Bible in this way. All the evidence we have clearly points to a very old Earth where most changes in the landscape have taken millions upon millions of years.
 
And vandalizing park signs is not going to change that.

Knowing the Humans Behind the Cultured Cells

0 Comments

The development of the capacity to culture cells ushered in a revolution in the biological sciences because it allowed scientists to remove cells from the great complexity of the live organism and grow them in a controlled environment where they could study the chemical and physical changes that the cells exhibited during their life cycle in response to both normal and pathological stimuli. The nature and role of many molecules and fundamental processes going on in living things have been discovered thanks to cell culture research, and this has in turn allowed the development therapies for many diseases. Additionally, cells have also been used as tools to screen for new drugs, grow pathogens, test the effects of changes in genes, and in the future may allow the creation of replacement organs.
 
During my scientific career, I have worked with many cells including human cells. Most of the human cells I have worked with were cancerous cell lines derived from tissues such as breast, pancreas, ovary, colon, and cervix. The way these cell lines are generated is that they are initially isolated from a cancer found in an organ, and they are then grown in culture flasks for several generations. Once enough cells are available, they are frozen and stored under conditions that do not harm them, and they can be packed in dry ice and shipped to laboratories around the world. Nowadays you can buy these cells from companies that have divisions that are specialized in cell culture.
 
When I do an experiment with human cells, I am primarily focused on getting the science and the procedure right. However, when I peer through my microscope at those tiny things that swarm and multiply in my culture flasks, I sometimes wonder about the human beings from whom they were taken. Who were these individuals? What did they do? Where did they come from? What challenges did they face in life? What were their opinions about local and world events and trends? What foods and music did they like? What books did they read? Were they killed by their cancers? How would they feel if they knew that I am looking at cells from their breasts or their prostates?
 
When you purchase a cancer cell line, there is very little information available regarding the person from whose cancer the cells were generated. Normally only the age, sex, and ethnicity of the person are provided. Consider the most famous of all cell lines: the HeLa cell line. This was the first cell to be cultured, and it played a crucial role in the process that led to the development of the polio vaccine. The HeLa cells were isolated from a cervical cancer which killed a black woman named Henrietta Lacks in 1951. Since then, these cells have been extensively used for research all over the world and the story of Henrietta Lacks and her cells has been told in a remarkable book by Rebecca Skloot entitled, The Immortal Life of Henrietta Lacks. But if you purchase a vial of HeLa cells today, the only information presented regarding the person from which they were obtained is:
 
Age: 31 years adult
Gender: Female
Ethnicity: Black
​
Picture
Henrietta Lacks and Her Cells
There is extensive documentation regarding the genetic, biochemical, and physiological characteristics of the cells, as well as information regarding how to grow them and references to their use in research, but there is no information about Henrietta and her life. And some scientists would argue that, in addition to privacy issues regarding the individuals and their families, this is OK because cells are a tool, and any personal information regarding the individuals from which they originated is irrelevant.
 
Although I understand this argument, I still would like to know a little more about those individuals whose cells I am culturing and how they feel about it. I believe that if someone is donating their cancers to research, they should be given the option to at least write a few lines to the scientists that will be using their cells. For example:
 
Dear Researcher,
My name is Jane Doe. My doctors tell me that the cancer they will remove from my ovaries will be used to produce cell lines for research. I am praying that the surgery and the chemo will work, and that I will be able to spend more time with my daughter and my grandchildren. However, I want you to know that regardless of the outcome, I want you to make good use of my cells and find ways to treat this and other diseases. We all appreciate more time in this world, and I hope that God guides your studies and blesses you with clarity. When you peer through your microscope and look at my cells, I may be long gone, but remember that you will be handling a part of me that will outlive me and which represents a little of what I once was. So please take care of my cells and good luck in your research!
 
or
 
Dear Scientist,
My name is John Doe. I have lived through a lot. I have been in wars. I have been shot. I have stared death in the face many times and survived. So it’s a bit ironic that this colon cancer may be the thing that brings me down, but we all sooner or later have to accept our fate. The doctors say they will use the cancer they take out from me to produce cells for research. It feels a bit strange to know that there will be a bunch of strangers handling cells from my colon, but if this helps to treat this disease, I am all for it. I love my country, and I value the time I spend with my family, and with my fellow vets when we get together to have some beers every now and then. I would appreciate any extra time I can spend with them, but if I can’t do it anymore, I hope your research will allow others that chance. So please make good use of my colon cells and have a beer for me next time you go to a bar with your research buddies. Godspeed.
 
Including notes such as these in the information available in human cells used for research would give a little more humanity to the process as well as perspective and motivation for those of us using these cells.

Even More Terrible Science Jokes and Puns

0 Comments

A while ago, I posted some science jokes in my blog. I followed that by posting some terrible science jokes and puns, and then more terrible science jokes and puns. Today I present to you even more terrible science jokes and puns, along with (when necessary) an explanation of why they are funny.
 
The chemistry student e-mails his professor claiming that he has been able to react lithium with argon. The professor replies to the e-mail by writing, “You are a LiAr”.
Argon is an element that doesn’t react with any other element. The chemical symbols for lithium and argon are, “Li” and “Ar”, respectively. If lithium did react with argon the formula of the resulting compound would be “LiAr”. The play of words is with liar as in a person who utters falsehoods.
 
Q: What was the name of the first electricity detective?
A: Sherlock Ohms
The Ohm is a unit of electrical resistance named after the German physicist George Ohm. The play on words is with Holmes, the surname of the famous detective character created by the British writer Arthur Conan Doyle.
 
The wife of the logician says, “Can you please go to the grocery store and buy one carton of milk, and if they have eggs, get six.” The logician leaves and returns with six cartoons of milk. Puzzled, the wife inquires, “Why did you buy six cartoons of milk?” The logician replies, “They had eggs.”
As Sherlock Holmes would say, “Elementary.”
 
I blew up my lab doing a chemistry experiment. Oxidants happen.
A play on words on “accidents” and “oxidants”, which are chemicals that can react very strongly and can be hazardous if not handled safely.
 
The scientists Einstein, Newton, and Pascal are playing hide and seek. Einstein covers his eyes and counts while Pascal hides, but Newton stands behind Einstein and draws around himself a one meter by one meter square box in the ground. Einstein finishes counting, turns around, and opens his eyes. Upon seeing Newton in front of him he says, “I’ve found you Newton, now you’re it”. Newton says, no you haven’t found me, you’ve found Pascal.
A Newton is a unit of force named after the English scientist Isaac Newton. A Pascal is a unit of pressure named after the French scientist Blaise Pascal.  A Pascal is a force of one Newton applied to a surface of one square meter. The joke is that because Newton was standing on a square meter, he was really a Pascal (a Newton applied to a square meter), so Einstein had found Pascal, not Newton.
 
Q: What kind of bear dissolves in water?
A: A polar bear!
Compounds that have positive and negative charges are said to be polar. These compounds can easily dissolve in water by interacting with the water molecules. The play on words is with the type of bear (a polar bear).
 
Heliocentric System: the Earth and the planets revolve around the sun.
Geocentric System: the sun and the planets revolve around the Earth.
Egocentric System: everything revolves around you.
I’ve met a few people during my lifetime who believed in this last system.
 
The chemist says, “Alcohol is not a problem. It's a solution.”
As in a liquid.
 
There are two kinds of people in the world: Those who can extrapolate from incomplete data...
And if you can’t figure this one out, you belong to the other kind.
 
Q: Who led the people of Israel across a semi-permeable membrane?
A: Osmoses
The process by which molecules of a solvent cross a semipermeable membrane from a less concentrated solution to a more concentrated solution is called osmosis. This is a play on words on the Moses of the Bible.
 
Q: What is BUNNY-O-BUNNY
A: Ether Bunny
An ether is a chemical entity where two identical molecules (R) are joined through a bond with an oxygen (O) in a manner described as “R-O-R”. In the above case the “R” molecule is “bunny”, and the resulting ether (ether bunny) is a play on words on Easter Bunny.
 
The professor said wryly to his students, “Remember, a couple of months spent in the laboratory can save you a couple of hours in the library.”
The normal advice goes in the opposite direction.
 
Q: What did the stamen say to the pistil?
A: “I like your style."
The stamen is the male organ of a flower, and the pistil the female organ. The style is part of the pistil. The play on words is with “style” as in elegance or refinement.
 
Sodium sodium, sodium sodium, sodium sodium, sodium sodium, sodium sodium, sodium sodium, sodium, BATMAN!
In the original Batman series from the 1960s staring Adam West as Batman, the lyrics of the show’s theme song featured a section (which can be heard 35 seconds into this video) that went: Na Na, Na Na, Na Na, Na Na, Na Na, Na Na, Na, Batman! The joke is that “Na” is the chemical symbol for sodium.
 
To impress a lady, the nerd says to her, “You must be made of uranium and iodine because all I can see is U and I.” The lady replies, “Wow you must be a germanium-nickel-uranium-sulfur, eh?”. They nerd says, “Well, yes, thank you.” The lady then adds, “You also obviously don’t understand sulfur-argon-calcium-samarium.”
The chemical symbol for the element uranium is “U” and the one for the element iodine is “I”. The chemical symbols for germanium-nickel-uranium-sulfur spell “Ge-Ni-U-S”, but the chemical symbols for sulfur-argon-calcium-samarium spell “S-Ar-Ca-Sm”.
 
The mathematician told a joke. He said, “There is a fine line between the numerator and the denominator”, but only a fraction of the people got it.
The top number of a fraction is the numerator while the bottom number is the denominator, and they are separated by a fine line (the division symbol).
 
The geology student said, “Of quartz I love geology, it’s just that I don’t take it for granite.”
Play of words of “of quartz” as in “of course”, and “granite” as in “granted”.
 
And now for the Grand Finale!
 
I think the name “Saturn” has a nice ring to it.
I am mindful of gravity because, after all, it’s the law.
I think that supernovas are a blast, but black holes suck.
I’m reading a book about anti-gravity, and I can’t put it down.
I have a new theory of inertia, but it doesn’t seem to be going anywhere.
I told a story in science class to illustrate the effects of friction, but it was a drag.

I did not invest in the company that wants to build a time machine, because I think it has no future.

The Monsters Produced by the Sleep of Reason and Their Effects on the Dynamics of Reality

PictureThe Sleep of Reason Produces Monsters
In 1799, the Spanish painter Francisco Goya published a compilation of 80 aquatinted etchings (the Caprichos series) in which he criticized the irrationality and ignorance rampant in the Spanish society of his time. The most famous of these etchings depicts a writer asleep at his desk surrounded by bats, owls, and other creatures swarming about him that in Spanish folklore were associated with the mysterious and evil. The title of the etching, written on the desk of the writer, is “the sleep of reason produces monsters”.
 
I am writing this post in the year 2021 in the United States, and although a gulf of 222 years and more than 3,000 miles separate me from the Spain of Goya, it is my opinion that Goya’s thinking is very relevant to our society today. In the past few years, we have all witnessed with growing frequency how reason has slumbered in the minds of millions foisting a number of monsters upon our society.

We have seen firsthand how disinformation and misinformation have spread like cancers capturing the imagination and wills of people and spawning things like disdain for journalists and scientists, COVID-19 severity denial, and vaccine hesitancy. We have experienced an unprecedented level of polarization in our society to the point that those seeking a middle ground are attacked and ridiculed. We have seen how millions have insulated themselves from ideas and opinions that go against their beliefs, preferring instead to listen to those that tell them what they want to hear. We have seen the rise of philosophies, narratives, and frameworks of knowledge that run contrary to reality, ranging from isolated unfounded conspiracy theories to warped world views like QAnon.
 
One example of a particularly dangerous monster is the skepticism regarding the 2020 election. Many Americans have been fed misinformation that this election was a fraud, and many Americans have believed it despite the fact that no evidence has been uncovered that indicates this is the case. And perhaps one of the most memorable portrayals of the mindset of the fraud believers was revealed in Jan 4, 2021 during the Fox Business Network program “Lou Dobbs Tonight” by its host Lou Dobbs who had been a frequent broadcaster of conspiracy theories. Dobbs was interviewing the director of a pro-Trump Political Action Committee (PAC), and he said the following:
 
We’re eight weeks from the election, and we still don’t have verifiable, tangible support for the crimes that everyone knows were committed, that is, defrauding other citizens who voted with fraudulent votes. We know that’s the case in Nevada, we know it’s the case in Pennsylvania and a number of other states, but we have had a devil of a time finding actual proof. Why?
 
Many eyes opened wide, and jaws dropped that day. Here it was, revealed in all its brutal matter of fact casualness for all the world to see: the sleep of reason.
 
Although Dobbs to his credit, and unlike many fraud believers, did admit that there is no evidence for the fraud claims, he then goes on to state that everyone KNOWS that such fraud happened, and wonders why it is so hard to find the evidence. The disconnection is glaring! We normally base our knowledge that something has happened on evidence, therefore lack of evidence cannot support such knowledge. Reasonable people would accept that knowledge that is unsupported by evidence is not trustworthy and, in fact, is not knowledge at all – reasonable people. Only two days later Americans came face to face with the monster spawned by this irrationality when a mob of Trump loyalists stormed the Capitol seeking to overturn the results of the election and to harm or kill our elected representatives.
 
While many dismiss the storming of the Capitol as the actions of a few, there are millions of people that still believe that there was fraud in the elections. And while most of these people don’t sanction the extreme behavior exhibited by the criminals who stormed the Capitol, these people can vote and request that their elected representatives act on their will.
 
At the time Goya made his famous etchings, the system of government in Spain and many other countries was a monarchy. In such a system the average citizen has little influence on the actions of their government and how it affects them. However, the United States is a democracy. In this system, the people elect their leaders and can pressure them into taking certain actions. This is the strength of democracy, but it can also be its weakness if a significant number of people who are not acquainted with reality elect and pressure their representatives into supporting fictions. The current modifications to election practices that are being enacted in several states are an example of this.
 
It is not my intention to issue an opinion on the merits of these modifications, but I just want to point out that these modifications are being implemented mostly in response to skepticism about the validity of the 2020 election. However, because based on the evidence this skepticism is unwarranted, it follows that the enactment of these modifications is unwarranted too. Rather than being proud of the fair and transparent 2020 elections with a historic turnout, a significant part of our population views them with suspicion or is convinced that fraud took place and that something must be done about it. And this, of course, can affect the dynamics of reality. If a substantial number of people elects and pressures their leaders to uphold a fiction, this fiction in terms of its consequences paradoxically will turn into a de facto reality that will affect others.
 
It is important to counter misinformation and fight for the wills of those who have accepted it or who are considering accepting it. It is important to awake reason and vanish the monsters that its slumber has begotten. Goya understood the danger of the sleep of reason more than 200 years ago, and we must also understand it today, and with more urgency because in a democracy the people have the power to alter the dynamics of reality. And we cannot allow reality to be compromised.
 
 
The etching by Goya is in the public domain.

Taking a Look at the Things That We Fear

0 Comments

Read Now
 
I have written before about fear, which is one of the strongest emotions humans experience. Fear can be a useful emotion that prevents us from doing things that may hurt us or place us in danger. However, excessive fear can have a detrimental effect on our lives by producing an incapacitating anxiety or even panic which can significantly interfere with everyday life and cause health problems. There are specific fears called “phobias” that involve an irrational fear of a specific object or situation. These phobias may be caused by a bad experience, which normally occurs during childhood, or they may have genetic origins. Those who experience these fears recognize their nature and tend to avoid the object or situation that triggers the phobia. The lifetime worldwide prevalence of these phobias is very variable affecting anywhere from 1.5% to 15% of the population. Phobias tend to affect women more than men, and they tend to begin in childhood and decline thereafter with peaks during midlife and old age.
 
Human phobias run the gamut from the slight to the severe and from the common to the truly rare, and they can affect people ranging from average persons to celebrities. In this post we will take a look at some specific fears that people have.
​
PictureAligatoraphobia
The most common phobias involve animals, and they are in general called zoophobias. I once knew a kid who would scream and run away from large dogs. He had a type of cynophobia, which is the fear of dogs (the fear of cats is ailurophobia). The actress Kristen Stewart has a fear of horses (equinophobia), which she had to overcome to film a movie that involved a lot of horseback riding. There are people who are afraid of alligators (aligatoraphobia). This is a specific case of herpetophobia or fear of lizards and snakes. The country singer and songwriter Johnny Cash was afraid of snakes (ophidiophobia). But the object of the fear doesn’t have to be a large scary creature. I knew of a person that was so terrified of frogs that she would faint in their presence. This person had ranidaphobia, which is a specific case of the broader batrachophobia, or fear of amphibians. The feared animal can in fact be something much smaller such as an insect (entomophobia). The singer Justin Timberlake is afraid of spiders (arachnophobia) and the actress Nicole Kidman is afraid of butterflies (lepidopterophobia).
 
Other common fears are phobias such as fear of heights (acrophobia). A related phobia is fear of flying (aviophobia). I knew a person who could only board a plane under heavy sedation, as that was the only way this person could tolerate flying. The great science fiction writer Isaac Asimov who wrote about flying to the stars had both acrophobia and aviophobia, and he would only travel by vehicle, train, or ship. There are people who are afraid of thunder and lightning (astraphobia), of tight or crowded spaces (claustrophobia), of blood (hemophobia) and even of water (aquaphobia). People with aquaphobia can drink water but they are afraid of larger amounts of water as in oceans, lakes, pools, and even bathtubs. Aquaphobia should not be confused with hydrophobia which is a symptom of the late stages of the disease, rabies. A common and sad phobia is the fear of being alone (autophobia), which can lead people into bad relationships just to avoid being single. Another common phobia is the fear of driving which is known by several names (amaxophobia, ochophobia, motorphobia, or hamaxophobia). This phobia is often combined with other phobias such as dystychiphobia (fear of accidents), hodophobia (fear of travel), or capiophobia (fear of getting arrested).
 
There are other phobias that are less common, but still affect a significant number of people. I once knew of a war veteran who could not stand celebrations involving fireworks. He suffered from ekrixiphobia, the fear of explosions. People who are afraid of getting cancer have carcinophobia. This is a specific case of the more general nosophobia, which is the fear of developing a disease. People who are pathologically afraid of germs have (mysophobia). The fear of suffering an amputation and of being around amputees is called (apotemnophobia). And as you would expect, the area of sexuality is rife with its own array of phobias that fall under the general fear of sex (genophobia) denomination.
 
Finally, there are rare phobias some of which may seem truly bizarre.
 
The fear of belly buttons is omphalophobia.
The fear of objects inside one’s house is oikophobia.
The fear of peanut butter sticking to the roof of your mouth is arachibutyrophobia.
The fear of the color yellow is xanthophobia.
The fear of mothers-in-law is pentheraphobia.
The fear of being afraid is phobophobia.
The fear of money is chrometophobia or chrematophobia.
The fear of happiness is cherophobia.
Perhaps the most ironic of all phobias is, hippopotomonstrosesquippedaliophobia, which is the fear of long words!
Some people, such as the film director Woody Allen, have so many phobias, that they are said to have panophobia, which is the fear of everything.
 
Some of the above phobias may seem risible, and in fact very specific phobias have been often the subject of ridicule. The British program The Sketch Show parodied phobias in its Phobia Workshop sketch shown in the video below.
​


​We may be tempted to dismiss some of these rarer phobias as the absurd quirks of eccentric people with too much time on their hands, but if these phobias are severe enough and the stimulus that triggers them is hard to avoid, they can be a source of shame and anxiety that disrupts the life of the individuals afflicted with them and isolates them from society.
 
Phobias can be treated in several ways. One of them is graded exposure to the trigger of the phobia (exposure therapy) in a controlled environment which nowadays may also involve the use of virtual reality technology. Another treatment is cognitive behavioral therapy which focuses on changing the thoughts and beliefs people have about their phobias. In the more extreme cases, medications such as antidepressants and anxiolytics may be necessary.
