Although my posts for the next few weeks are mostly going to be repeats as the website gets built, I couldn’t help but write up this story about willow tree bark and aspirin. Dear reader, you, like me, may have been under the impression that for millennia, people in different parts of the world relied […]

The Robledo Mountains lie to the north of Las Cruces, New Mexico, and to the east of the Rio Grande continental rift. Much of the exposed rock is from about 280 million years ago (Paleozoic), and the geological footprint is obvious and amazing. You can see a slot canyon in most of these pictures, when
These statues are some of the remaining examples of “mushroom stones” from the Ancient Maya people. They testify to the usage of psilocybin by indigenous Central Americans that goes back hundreds of years. The second photo shows a real-life example, called Psilocybe Mexicana. The Central American consumption of hallucinogenic mushrooms for ritual purposes was brought

These photos taken last weekend show vistas along the Loyalsocks Trail, one of the many stunning forested hiking pathways in Pennsylvania. Taking its name from the Loyalsock Creek (which translates from an American Indian name for “middle” creek), the Loyalsock trail is nearly sixty miles. The portions shown here include Sones Pond, which was built
These figures painted in the Manda Guéli Cave in central Africa in prehistoric times show humans amidst animals they have domesticated. They illustrate the importance of pastoralism in human history, which isn’t just something that changed some people’s food supply (instead of foraged plants and animals, pastoralists focus on the nutrients from their domesticated beasts).

Flick through these three images, dear readers, and you will observe something that scholars have been looking for for over 2,000 years — finally brought to light via a student class project, the COVID lockdowns, and state-of-the-art multispectral imaging. It is the oldest star map of the universe. The manuscript you see is the _Codex

London’s East Smithfield Cemetery made news this week because of a recent study suggesting that the Medieval Black Death provided impetus for human evolution in a way that shapes many of our genomes today. With the advent of technology that allows for whole genome analysis of the dead, scientists and historians decided to exhume skeletons

Finding a more arcane and mysterious text than the Voynich Manuscript would be difficult. Written in 1420, the script has thwarted the world’s best cryptogrographers – linguists have failed alongside computer A.I specialists to decode the 200-page book. Just yesterday a story broke that a British linguist has solved the code – he claims the

Here are four rats rowing a tiny boat, painted in a 14th-century French book. Such an image calls to mind the rats that spread the plague bacterium Yersinia pestis during the worst pandemic in human history: the Black Death. The theory goes that rats carrying the infected fleas spread the bubonic plague that ended up
Twenty-one years ago in 2001, the Burd Run Nature Trail and Restoration was established to reverse the damaging effects of an artificially straightened stream channel which had caused erosion and environmental degradation. (See second image). Shippensburg University (particularly the Geography and Earth Science Department), Shippensburg Township, the Cumberland County Conservation District, and the Conodoguinet Creek

The two pictures in this post seem to have nothing to do with each other, but they are connected by a surprising history: “white gold,” aka guano, i.e. bird excrement. This stuff once drove human cultures in these now depopulated areas. The first image shows the Atacama Desert of Chile, the driest non-polar desert in
My science feeds are abuzz with the story behind an article published this month of November 2022 in _Nature Ecology & Evolution_ that redates a human invention — deliberate cooking of food — to 780,000 years ago, long before Homo sapiens evolved. The species Homo erectus (see first image) is the likeliest human ancestor that

Between 1582 to 1589, the British occultists John Dee and Edward Kelly claimed to have received multiple messages from angels. Writing these transmissions up, they formed the basis of the Enochian magical system, which was re-discovered and popularized over 300 years later by Alistair Crowley, a controversial (and free-love promoting) spiritualist. Pictured here is a
Syphilis caused widespread suffering in Early Modern Europe – this portrait by Rembrandt van Rijn of a sufferer from about 1665 illustrates the facial deformities that occurred as the disease progressed. Scientists still debate where the disease originated, but one idea is that strains of the bacteria causing syphilis had developed independently Europe and in

Rocks! But wait, there’s more: the technology heralded by these Acheulean hand-axes that you see (noted for their pear and oval shapes) signify not just the very cutting-edge (groan) way to cut into bone developed between 2 and 1.6 million years ago, but also, the formation of human language and maybe even the genesis of

Look above the manager roof in this scene from Italian Renaissance master Giotto di Bondone’s _Adoration of the Magi_. The “star” that Giotto painted had been famous for centuries as the one featured in the Gospel of Matthew which inspired the wise men to travel to King Herod of Judea to inquire about the prophecy

Potential happy post-extinction post! The drawing you see here is artist Nirupa Rao’s rendition of a plant that some believe to be an extremely rare survivor of Silphium (also known as silphion), an Ancient Mediterranean species so valued that it was hunted to extinction — but maybe, believe some plant historians, it’s been rediscovered. I
Being a hat maker was a deadly profession of the 19th century, as the life of Boston Corbett (died probably 1894) shows. Corbett is most famous for being the man who shot President Lincoln’s assassin, John Wilkes Booth. Less well known is his unfortunate history of mental illness, likely caused or very much exacerbated by

Big history post here (big history meaning all of history, not just human), about the fabulousness of how evolution works. This is about the ways bees created the colors we see on flowers. We know that bees are super-pollinators critical for much of earth’s plant life. And we observe how bees are drawn to sweet

Ringing Rocks County Park contains a 7-acre boulder field with an unusual feature: about a third of these rocks clang with a metallic ring when struck. The boulder field reached its current position about 12,000 years ago when the last Ice Age melted the great Wisconsin Glacier away from this part of Bucks County Pennsylvania.
