Brainstem and spinal cord discovered in Michelangelo
Michelangelo, the 16th century master painter and accomplished anatomist, appears to have hidden an image of the brainstem and spinal cord in a depiction of God in the Sistine Chapel’s ceiling, a new study by Johns Hopkins researchers reports. These findings by a neurosurgeon and a medical illustrator, published in the May Neurosurgery, may explain long controversial and unusual features of one of the frescoes’ figures.
I took these pictures at the Mathematica exhibit at the Boston Museum of Science.
One of last week’s episodes of To the Best of Our Knowledge had a segment on the Garden of Cosmic Speculation (shown above) — a private garden created by architect Charles Jencks and his wife to explore scientific concepts with landscape. Very cool!
From the Neurophilosophy blog:
HIS is the left cerebral hemisphere of an 18-month-old infant who lived some 800 years ago. Such finds are extremely rare, because nervous tissue is soft and normally begins to decompose soon after death, so this specimen is unique in that it has been far better preserved than any other. Although reduced by about 80% of its original weight, many of its anatomical features have remained intact. The frontal, temporal and occipital lobes have retained their original shape; the gyri and sulci (the grooves and furrows on the surface, respectively labelled G and S, above) are easily recognizable; and deep within the temporal are the identifiable the remnants of cells.
The original manuscript of Albert Einstein’s groundbreaking theory of relativity, which helps explain everything from black holes to the Big Bang, went on display Sunday in its entirety for the first time. Einstein’s 46-page handwritten explanation of his general theory of relativity, in which he demonstrates an expanding universe and shows how gravity can bend space and time, is being shown at the Israel Academy of Sciences and Humanities in Jerusalem as part the scholarly association’s 50th anniversary celebration. First published in 1916, the general theory of relativity remains a pivotal breakthrough in modern physics.
Today, the phenomenology of the mind is stepping indignantly aside for a host of hyphenated disciplines such as neuro-anthropology, neuro-pedagogy, neuro-theology, neuro-aesthetics and neuro-economics. Their self-assurance reveals the neurosciences’ usurpatory tendency to become not only the humanities of science, but the leading science of the twenty-first century. The legitimacy, impetus and promise of this claim derive from the maxim that all human behaviour is determined by the laws governing neuronal activity and the way it is organised in the brain.
Whether or not one accepts the universal validity of this maxim, it is fair to assume that a science that aggressively seeks to establish hermeneutic supremacy will change everyday capitalist reality via its discoveries and products. Or, to put it more cautiously, that its triumph is legitimated, if not enabled, by a significant shift in the capitalist world order.

Scientists have unearthed an almost perfectly preserved spider fossil in China dating back to the middle Jurassic era, 165 million years ago. The fossilized spiders, Eoplectreurys gertschi, are older than the only two other specimens known by around 120 million years.
A complex symmetric structure known as theexceptional Lie group E8, which has so far only existed in the minds of mathematicians, seems to have turned up in real life for the first time.
Scientists have built a clock which is 100,000 times more precise than the existing international standard.
“One Cubic Foot”
From National Geographic:
How much life could you find in one cubic foot? That’s a hunk of ecosystem small enough to fit in your lap. To answer the question, photographer David Liittschwager took a green metal frame, a 12-inch cube, to disparate environments—land and water, tropical and temperate. At each locale he set down the cube and started watching, counting, and photographing with the help of his assistant and many biologists. The goal: to represent the creatures that lived in or moved through that space.
