“The good thing about science,” writes astronomy popularizer Neil deGrasse Tyson, “is that it’s true whether you believe in it or not.” One could also state that the opposite can be the case — merely wishful thinking will not alter the rules of the material world. Or the biological one. But this is not what […]

The two pictures shown here accompanied two of the most important “aha!” moments in history. The first is “Photo 51,” taken under the laboratory research of Rosalind Franklin. It shows an X-ray diffraction pattern of DNA, and Franklin, Watson, and Crick used it to figure out the molecular structure of life itself.The second is a

The Scientific Revolution that developed in Europe did not always lead to the embracing of rationality. This engraving by William Hogarth from 1751 is a case in point. You see in this image a grand display of the dissection of a corpse at the hands of professional anatomists. Yet even though the endeavour might have

This week’s stories focus on a subject in science history which is indeed topical across the world right now: the discovery of how the human immune system works. And to begin, I am introducing the image of this young girl, named Myrtis by the Greek archaeologists who reconstructed her appearance after excavating a mass grave

Today on December 14, 2020, a critical care nurse in New York became the first American to receive the COVID vaccine. This begins a period of highly anticipated vaccine delivery in the weeks to come. The photo here harkens to another moment in American history when folks waited with bated breath for a cure for

Shown here are Doctors Pear Kendrick and Grace Eldering, and together they developed the first successful vaccine against the childhood disease pertussis, or Whooping Cough.Whooping Cough is of course characterized by the sound of the hollow, forced, and unremitting chest cough that mostly younger people endured until the 20th-century development of a vaccine: it killed

This week’s posts feature great moments in the history of immunology. Although the death of Vizzini (and corresponding survival of the hero Westley due to his years of building up immunity to iocaine powder, among the deadlier and fictitious poisons known to man) in _The Princess Bride_ might be famous in terms of cultural history,

In this last post for the week to focus on great moments in immunology, I feature a rare time when biologists actually got their naming system right.Featured here is an Ancient Roman copy of a Greek statue featuring Artemis. Although usually known as the Goddess of the Hunt and wilderness, the moon, and female chastity,

In _Star Trek II: The Wrath of Khan_, the famous first lieutenant Spock airily quips to Dr. McCoy that “as a matter of cosmic history, it has always been easier to destroy than to create.” At the end of the film, the Vulcan sacrifices his life to prevent the destruction of the entire crew, because

This disgusting, but hardly pornographic, illustration of a monk with open lesions on his penis is illustrative of the horrific pandemic of Syphilis that emerged in Europe in the late 15th century. Causing sores on genitalia in its first phase, the disease eventually results in ulcers, hair loss, and physical dismemberment among other things before
Epidemic of Syphilis in the 15th-Century Read More »
For centuries, Europeans’ #1 go-to treatment for the disease Syphilis was an administration of mercury. Physicians managed it via theraputic fumigation, through injections, and as topical creams – often in the form of mercurous chloride, called “sweet mercury” or “calomel”. As the 16th-century poem “Syphilis” notes: “All men concede that mercury’s the best/ Of agents that will

What can anal fistula teach us about Medieval life? A great deal, tuns out.The first image you see here is a 15th-century illustration of one of the most important medical treatises of the Middle Ages, the “Practica of fistula in ano.” It is all about how to cure diseases of the colon and rectum, including

Yesterday I wrote about a certain physician, John of Arderne, who wrote an amazingly forward-thinking text about how to perform a surgery on anal fistula. Unique for his time in the 1300s, he emphasized the importance of hygiene and correct methods to prevent blood loss during the painful operation. Lest you think that anyone, even

You’re looking at a 700+ year-old heart, recovered from a Medieval autopsy of Saint Clare of Montefalco, and considered a miraculous relic demonstrating Clare’s special relationship to God. Also did I mention that this is an actual heart?When super holy people — I mean “athletes for God” holy– died, Ancient and Medieval Christians thought they

Check out this recently discovered mummy with a gold-foil tongue — It’s about 2,000 years old and comes from the Ancient Egyptian city of Taposiris Magna. Scholars believe the special tongue was to be able to speak in the afterlife — maybe to answer to Osiris, the divine judge of the dead.News of this discovery

My historical fields of interest lie in the distant past — but for me, it seems almost ancient history to realize that a year ago today on March 11, 2020, the World Health Organization decreed that COVID-19 was indeed a pandemic, and the world changed utterly.That was before the deaths of nearly 530,000 Americans (so

So it’s still Women’s History Month, and since I adore history and science, I wanted to do this entry about the American astrophysicist Cecilia Payne-Gaposchkin, whose contributions to our knowledge about the physical makeup of the universe were relatively unknown for much of the 20th century.Here you see Cecilia Payne’s portrait by artist Patricia Watwood,

In 1985, scientist, Katalin Karikó left her native Hungary for the United States with her husband and two-year old daughter. The University of Szeged, where she had earned her degree and was working as a postdoctorate fellow, had run out of funding. So the family — who had to sew cash into their daughter’s stuffed
It fits that the grave of Carl Bosch in Heidelberg is overgrown with the competing green textures of the jumble of plants collecting at his tombstone. Plants were something Bosch understood more than most people — and that, combined with his engineering skills, got him the Nobel Prize in Chemistry in 1931. A just reward,

These Chinese tiny stick drawings contain precious information — very few could understand it in the second century BCE when they were inscribed in silk and placed in the famous Mawangdui tomb, but modern astronomers have studied such markings to learn about the history of celestial objects of the distant past.These are renderings of different
