The way medical knowledge has spread across the globe over time is fascinating. Now, of course, the internet makes things easy — that’s why the mRNA technology that produced two of the major COVID vaccines could be developed so quickly. Throughout recorded history, the Ancient Greek tradition was the most influential source of medicial studies […]

This is the super cool Nebra Sky Disk, which most archaeologists think is the oldest picture of an actual astronomical scene. Looking at the bronze (the blue-green patina might have been deliberate) background with the gold ornamentation, ancient peoples could have been able to figure out when it was time to put an extra month

Here is a handsome example of a Brood X cicada, after emerging from its hole underground (second photo) of seventeen years. These “periodical cicadas” are the insects that spend the longest amount of time developing from egg to adult. And their history is fascinating.The European settlers who came to North America were reminded of locusts

Today’s post is about the history of a symbol — one which appeared in numerous civilizations across time and whose meaning reflected the concerns of each culture it appeared in. I’m talking about the snake that eats its own tail — the ouroboros.In Ancient Egypt the ouroboros appeared in the 13th-century tomb of “King Tut”

If you think of the words “occult”, “arcane”, or “mystical” when you look at this Medieval text, you aren’t alone — the association of the Middle Ages with backwardness and the irrational has a long tradition. But it wouldn’t be a correct impression, at least not entirely. And this manuscript shows why. Written in 1393

The lunar crater you see here is Aristarchus, and we’re not going to be be able to get any closer than that to an accurate portrait of the eponymous Ancient Greek astronomer because most of his writings — as well as any contemporary sculpture or paintings of the man — are lost to the sands

This is Polly Matzinger, and even though this is a history Instagram post, she is an active scientist. But her discoveries about the way the immune system works have changed how scientists think about the ways living things fight off harmful pathogens, thus ensuring Matzinger a place in humanity’s historical records.Before I say anything about

“I’m gonna have to science the shit out of this,” says the main character of Andy Weir’s _The Martian_, and proceeded.to use every bit of his resourcefulness to harness the power of knowledge to save himself. That movie is fictional, but actual scientists have done this (Hello, COVID-19 vaccination developers, I’m talkin’ to you there).

Those of us who love travelling to new places enjoy the sensation of adventure and the way it makes us open to learning new things, but few of us today risk our lives for such experiences. However, Maria Sibylla Merian was different. In 1699, this affluent 52-year old divorced mother of two left her affluent

If you are reading this post, I hope you can celebrate the fact that your profession is not as wretched as the Resurrectionists of Britain, and your post-mortem reputation as wretchedly public as that of William Burke, a Resurrectionist so desperate that he became a murderer for his career.In the 18th and 19th centuries, scientists

Scientists with scruples make for some of my favorite heroes. Here is one of them: Frances Oldham Kelsey.In 1960, in her first assignment on the first month at her new job at the United States Food and Drug Administration, Kelsey stood up to powerful corporate interests and demanded scientific studies to demonstrate the safety of

This is Ilya Ivanov, sometime known as the “Red Frankenstein” because of his experiments with inter-species breeding.In the early days of communist Russia, Ivanov earned a reputation for developing artificial insemination techniques that allowed him to develop hybrids of closely-related species: “zeedonks” (zebra with donkey), “zubrons” (European bison with cows) and sundry blends of rabbits,

Epidemiological studies is a fascinating blend of science and history. There’s a lot of ways we can benefit now from the study of past disease. The pock-marked friars shown here might well have been suffering from an illness that most folks today are blessedly free from: measles.Measles is a human virus (MeV), but, like SARS-COV2,

This political cartoon of Serge Voronoff (1866-1951) shows him as a circus performer, reaching into the gut of an exotically dressed assistant while masses of people line up to watch the operation. Voronoff detested this sort of depiction, because he took his work extremely seriously. After all, he was considered a leader in organ transplant

Today’s post is about paint colors — with the growth of modern chemistry (particularly Germany in the 1800s and beyond), making artificial pigments of various hues has been relatively easy. But it was not always so. Purple of course was the most famously sought-after hue, but I am featuring two others here: ultramarine (as used

The most notorious surgery of the 20th century is the lobotomy, and the most infamous practicioner of this operation was the neurologist Walter Freeman (d. 1972). For a couple of decades in the mid-20th century, Freeman performed about 3,500 lobotomies on mentally ill patients, developing a technique of entering the brain through the eye socket

The product you see here turns out to have been ubiquitous and super important in recent world history: Pervitin was a methamphetamine synthesized by Germans in 1937, and the Nazis were addicted to it.In _Blitzed_, Norman Ohler reveals the macabre dependency of both Hitler and the Nazi military on drugs. The trajectory is fascinating: while

It’s difficult to make a hero out of Edward Jenner, the doctor who developed one of the earliest types of vaccinations (for smallpox), but did so by experimenting on a nine-year old kid (James Phipps, the son of Jenner’s gardener). That kind of callousness fuels the fire of all sorts of negative stereotypes about scientists,

We all know (some of us might still be sad about it) that Pluto was demoted to a “dwarf-planet” status back in 2006. In other news, however (and mayhaps this could make up for Pluto’s decline), some scientists have speculated that another planet — known as Planet Nine — might be orbiting our sun.Ideas about
