The long-term side effects issue

One of the lesser-publicized objections to taking the covid-19 vaccines is the fear that side effects may appear after many years. This is, on the surface, a more plausible cause of concern since the vaccines have been around for less than a year and we do not have any data on what effects it might have after periods longer than that. So it is not surprising that some people feel that the verdict is not yet in on long term safety.

But scientists say that this fear can be allayed by explaining how vaccines work. The fact that the vaccines provide immunity for long times, sometimes for life, is not because they stay in the body that long. After triggering the immune response and creating antibodies to the virus, they quickly degrade and go away.

The murky ancestry of John James Audubon

I know nothing about birds but was of course aware of the name John James Audubon who became famous for his books containing detailed and lavish color paintings of the birds of America. His name has been adopted by various ornithological societies and one hears references to his name all the time. For some reason, I had thought that he was Black and was thus surprised when I read this news item that the Audubon Naturalist Society is dropping the name because of Audubon’s unsavory history and racist attitudes that, among other things, involved slave trading. They are making this move as part of a nationwide trend of not honoring people who have been guilty of deplorable acts.

The most vaccinated region in the US is … Puerto Rico

Puerto Rico has become the most vaccinated region in the US and why that may be so is interesting.

Puerto Rico has fully vaccinated just over 73% of its 3.3 million residents, according to the US Centers for Disease Control and Prevention. That’s more than 2.3 million people.
…

On the mainland, Vermont leads with 70.8% of the population fully vaccinated, followed by Connecticut at 70.2% and Maine at 70%, according to the CDC, which added that just over 57% of the total US population was fully vaccinated as of Friday.

Dr. Ashish Jha, dean of the Brown University School of Public Health, wrote on Twitter that Puerto Rico’s “fabulous” vaccination efforts have “gotten way too little attention.”

One of the best arguments for getting vaccinated and wearing masks

And it comes from Fox News, of all places, and was made by host Neil Cavuto during an interview with Howard Kurtz. Cavuto has multiple sclerosis, heart disease, and cancer and is thus severely immunocompromised. He was vaccinated and contracted covid-19 and has recovered. He feels that being vaccinated was what enabled him to survive the breakthrough infection.

The rise and fall (and rise again?) of quicksand

Nearly four years ago, I had a post about quicksand. In it I mused how it used to be a common plot device in the books and films I watched and read as a boy but seemed to have faded from view. The 1962 film Lawrence of Arabia has a poignant scene with quicksand.

This week the program Radiolab had a segment on quicksand in which it turns out that my sense that quicksand was a significant feature of popular culture that has slowly disappeared has some empirical support. There is a database of films that have quicksand scenes in them and after starting out small in 1900 or so, the frequency of appearance increased, reaching a peak around 1960, and then decreasing again to the present day. That jibes with my personal experience.

Police and firefighters opposing vaccinations

On The Daily Show Trevor Noah comments on the odd fact that there seems to be high levels of resistance to getting the covid-19 vaccine among police and firefighters. The vaccine mandates issued by many jurisdictions that require all government employees to be vaccinated has resulted in many of them either leaving or challenging the mandates in court. Given that they pride themselves on risking their lives for the sake of others, this fear of taking a life-saving vaccine is puzzling. It may be that it is a higher level of general anti-vaccine and other right-wing ideology within these groups that is driving the resistance.

Popperians and Marxists

One of the things I noticed is that while I write and give talks lot about the philosophy of science, I get most pushback when I criticize Popper’s falsifiability idea (such as in my Scientific American article The Idea that a Scientific Theory can be ‘Falsified’ Is a Myth: It’s time we abandoned it) than any other thing I say. What is interesting is that I get challenged by both scientists and intelligent design creationists, who are usually on opposite sides of discussions about the nature of science. For example, at Why Evolution Is True, evolutionary biologist Jerry Coyne (and his commenters) disagreed with my article. And over at Evolution News intelligent design creationist David Klinghoffer also disagreed with me.

The religious exemption card is getting harder to play

In the US, claiming that some action is based on their religious faith tends to give people wide latitude. So it is not surprising that people reach for it even in situations where it is hard to discern any religious basis. We see this now as states and companies are issuing vaccine mandates requiring that their employees get vaccinated or conform to various kinds of other requirements such as regular testing or get fired.

But people who are trying to use religious exemptions to get out of vaccine mandates are not finding it as much of an easy sell as they might have expected. We saw how basketball player Andrew Wiggins had his request for such an exemption denied and now the head football coach along with four of his coaching staff of Washington State University were fired for not getting vaccinated as required for all state employees.

Ted Cruz told to butt out by Australian political leader

The chief minister of Australia’s Northern Territory did not take kindly to Ted Cruz criticizing his vaccine mandate, and told him to buzz off.

The scientific consensus on climate change is overwhelmingly strong

A new study finds that the scientific consensus that humans are altering the climate has passed the 99.9% level.

The degree of scientific certainty about the impact of greenhouse gases is now similar to the level of agreement on evolution and plate tectonics, the authors say, based on a survey of nearly 90,000 climate-related studies. This means there is practically no doubt among experts that burning fossil fuels, such as oil, gas, coal, peat and trees, is heating the planet and causing more extreme weather.

One has to parse statistics like this carefully to see exactly what has been measured.

The latest survey of peer-reviewed literature published from 2012 to November 2020 was conducted in two stages. First, the researchers examined a random sample of 3,000 studies, in which they found only found four papers that were sceptical that the climate crisis was caused by humans. Second, they searched the full database of 88,125 studies for keywords linked to climate scepticism such as “natural cycles” and “cosmic rays”, which yielded 28 papers, all published in minor journals.
…

“It is really case closed. There is nobody of significance in the scientific community who doubts human-caused climate change,” said the lead author, Mark Lynas, a visiting fellow at Cornell University.
