If 234 000 deaths from COVID-19 could have been prevented with a primary series of vaccinations (https://bit.ly/3XrFXfz) between June 2021 and March 2022, I estimate that 140 400 of these deaths would have been among Republicans. This is, of course, not a surprise because Republicans are less likely to be vaccinated…
One way of gauging the current diversity of cultures is to consider the range of responses countries made to the COVID-19 pandemic.120 There was, of course, some diversity, from the ultrastrict lockdowns in China to the more moderate response in Sweden. But the range of responses was far more limited than it could…
It’s not completely fanciful to say that science fiction began with three things: a dead frog, a volcano, and a teenage bride. The dead frog was one that an Italian physician named Luigi Galvani was experimenting with in the 1780s, when he found that a mild electric shock could cause the frog’s leg to twitch. It was…
Warm-blooded animals have an elaborate physiological control system to maintain a constant body temperature. In man, this temperature is about 37°C. Any significant deviation from this temperature puts stress on the body and makes it difficult to maintain metabolic processes at their normal rates. Why then, during…
To put our lower bound for fp into perspective, consider that approximately 41 400 (95% CI: 27 100–55 700) deaths per year are attributed to seasonal influenza epidemics in the United States [43] (and an order of magnitude more worldwide [44]). Taken at face value, our results indicate, for example, that if Embedded…
The most astounding example I encountered back in my early days studying Chinese was during a lunch with three graduate students in the Peking University Chinese department. I had a bad cold that day, and wanted to write a note to a friend to cancel a meeting. I found that I couldn’t write the character ti 嚔 in the…
A science-based example of a positive externality is vaccinations. Vaccinations work based on the number of people in the population who are vaccinated. Once a certain threshold is reached, the disease can't spread effectively and is essentially eliminated. As long as enough people are vaccinated, others who choose…
It is natural selection that gives direction to changes, orients chance, and slowly, progressively produces more complex structures, new organs, and new species. Novelties come from previously unseen association of old material. To create is to recombine.
What opposite discoveries we have seen! (Signs of true genius, and of empty pockets.) One makes new noses, one a guillotine, One breaks your bones, one sets them in their sockets; But vaccination certainly has been A kind antithesis to Congreve's rockets, ...
Another prime example of selection is resistance to penicillin. When it was introduced in the early 1940s, penicillin was a miracle drug, especially effective at curing infections caused by the bacteria Staphylococcus aureus (“staph”). In 1941, the drug could wipe out every strain of staph in the world. Now, seventy…
Medicinal discovery, It moves in mighty leaps, It leapt straight past the common cold And gave it us for keeps.
As we learn more about maternal hormones and their influence on the developing brain, scientists are beginning to propose actual biological mechanisms for the kind of folk prophecies that have been around for ages. One recent study, for instance, suggests that a child's shyness is determined, in part, by maternal…
In 1736 I lost one of my sons, a fine boy of four years old, by the small-pox, taken in the common way. I long regretted bitterly, and still regret that I had not given it to him by inoculation. This I mention for the sake of parents who omit that operation, on the supposition that they should never forgive themselves…
Initially, Almond doubted that the intrauterine conditions provided by a pregnant woman, even one sick with a virulent strain of the flu, could exert any lasting influence on her offspring. “When I started looking at the influenza pandemic, I was skeptical of the fetal origins hypothesis. I didn’t think I’d find any…
At this point I want to introduce a distinction between mind viruses that arose spontaneously and ones that were invented by human consciousness. I'll call the naturally arising ones cultural viruses and the human-crafted ones designer viruses. A designer virus is carefully crafted to infect people with a set of memes…
Those strains that reproduce persist; those that do not reproduce die out. The ability to reproduce is what makes living things different from rocks. Besides, there is nothing inconsistent with free will or even chastity in this view of life. Human beings, I believe, thrive according to their ability to take…
