In the remote grassy highlands of northern Ireland is the Sacred Heart Roman Catholic Church. There, three disprate landmarks – a cross, a grave, and some special dirt – tell a story about hope for an end to suffering.From the Medieval past, the tenth-century Boho High Cross depicts scenes from the Biblical Book of Genesis […]

There are two common denominators of the three scientists featured in this image. First, Anthony Fauci, Harold Varmus, and J. Michael Bishop spent decades of their lives devoted to searching for elusive causes and treatment of disease. Fauci worked on HIV among other illnesses, and Varmus and Bishop on cancer (the pair won the Nobel

We don’t need to wrestle with our beliefs to look at this image of a man undergoing bloodletting (about 1675) to know that this medical practice seems like a bad idea. Sure, the Ancient Greeks might have thought it could cure illnesses, but they had a totally incorrect idea that sickness originated in an imbalance

This is, most sadly, not a photo of my summer vacation — one can dream, though. And back in the Ancient Greek times, dreaming is exactly why people went to this place in Pergamon, which was a particular type of healing temple called an _asclepeion_.Named after the Greek god of medicine, asclepeions were visited by

One of the most macabre and unintentional poisonings in history is the sad case of the Bradford sweets killings of 1858. Twenty people died and over 200 sickened when they ate candy that had accidentally been prepared with arsenic. Kind of makes whatever mistakes we might be doing on Zoom this week seem a lot

In the entire history of the world, I challenge anyone to come up with a better name for a group of poisoners: may I introduce you to the Angel Makers of Nagrev.In the years immediately following the First World War, the small village of Nagrev in Hungary experienced an unusually large number of people –

You are looking at a rare Medieval illustration of the anatomy of a uterus. It is highly schematic/abstract, obviously, but the important bits for Medieval people were all there. At the top, you see a fetus (the Latin words used were “embryo,” “conceptus,” and “fetus”), and straight below it is the entrance marked “hec eat

We know that women in the Middle Ages wanted to have control over their ability to conceive, and medical texts from these centuries show that while women wanted to know how they could avoid getting pregnant, many were also concerned about infertility. After all, bearing children was considered the central function of women in this

You are looking at a page out of the Voynich manuscript, an as-yet untranslated text from the first half of the 15th-century. Shown is an illustration of what may be a type of sage plant. Many types of common herbs were likely taken as a means of birth control in the Middle Ages, but knowledge

The study of the history of birth control in the Medieval Isalmic world breaks a lot of stereotypes.According to the Islamic tradition recorded in the _Hadith_ (sacred Islamic scriptures accounting the sayings or deeds of the prophet Muhammad), sexual pleasure was something that married women (as well as men) had a right to. Although the

Evolutionary history is the focus of my posts for a while, and what better place to start than CRISPR? Last week, Emmanuelle Charpentier and Jennifer Doudna’s work in using CRISPR for gene editing made news headlines – this is the first time the Nobel Prize in Chemistry has been awarded to two women. The future

This is Marie-Claire King (born 1946), and just reading about her accomplishments makes me tired. Besides earning her Ph.D. from UC Berkeley, she has six other honorary doctorates in science from the most prestigious universities in the world. From her work in discovering the genetic foundations of breast cancer, schizophrenia, and hearing loss, to her

A few days ago I did a post featuring a fossil of a creature called Archaeopteryx, famed for having traits both bird- and dinosaur- like: it filled in a gap in the evolutionary record. The photo you see here is of the paleo-biologist Neil Shubin with a model of a creature whose fossils he found.

Historians are frequently enchanted by things discarded as useless by the general public. But I think anyone interested in evolution would find the study of non-gene coding DNA fascinating, including the scientist featured here. This is Susumu Ohno, one of the United States’ foremost geneticists and evolutionary biologists, and he came up with the term

“The Persistence of Memory” is one of artist Salvador Dali’s most recognizable paintings. The surrealist style is perfectly adapted to depicting the ways our minds preserve our memories — they are suggestive, dreamlike, warpable. For however imperfect or relativistic our memories might be, we owe them for much of our sense of identity.How we humans

Charles Darwin’s idea of Natural Selection as the key driver of evolution has been demonstrated many times over. However, in the century and a half since his lifetime, scientists have added onto his theories as various scientific discoveries have been made. Perhaps no one has reframed the picture of Darwinian evolution as much as the

What was it about Eastern Europe in the 1700s that brought about so many stories of Vampires? Some scholars note that Western European countries like Britain might have enjoyed these legends because they could make people feel civilized — those “eastern places” were rural, Catholic, superstitious, and backward in the minds of nationalist Brits.However, there

The global situation right now is dominated by discussion of COVID-19, as well as the Herculean attempts to create a vaccine for the disease. And as reports of the Phase III trials start to come in, we can look at this photo — a scientist’s laboratory from the early 20th century, cluttered and filthy. Rotting

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
