Scientists at the University of Copenhagen sequenced the oldest genome yet — 700,000-year-old DNA
from an ancient ancestor of the horse. The Nature Podcast explains why doing this is valuable
(and, no, it's not about creating a cloned ancient horse park) and how you go about sequencing such elderly, and thus degraded, DNA. — Maggie
You don't need to know an ancient language to help scientists read ancient literature. Researchers are looking for volunteers for a crowdsource project
aimed at transcribing (and, later, translating) the words written on a series of crumbling papyrus scrolls, found in a trash heap at the site of what was once Oxyrhynchus, Egypt. — Maggie
On Christmas Day, I watched a documentary about the terra cotta warriors — thousands of clay soldiers built as funerary objects for the tomb of Qin Shi Huang, China's first emperor. One crazy fact I learned: Unlike the type of lacquer we call shellac today (which comes from crushed beetles), ancient Chinese artists used a lacquer derived from the sap of the lacquer tree, a relative of poison ivy. Anybody tasked with the job of applying that lacquer can end up with
a serious allergic reaction
. Another fun fact: We've still never seen the inside of Qin Shi Huang's tomb. Partly, this is a bureaucratic issue. But the larger problem is the mercury-laden soil on top, possibly contaminated by Qin Shi Huang's tomb, itself, which was supposed to contain a scale model of his empire
, complete with rivers and oceans flowing with (you guessed it) mercury. — Maggie
Zigong Dinosaurs World Science & Technology Co.,Ltd. makes, as you can probably guess from the name, animatronic dinosaurs. Which, for some reason, they attempt to sell via spam email marketing. We at BoingBoing have gotten spam like this before, from other manufacturers in the surprisingly robust Chinese animatronic dinosaur industry. What made this particular email stand out to me, though, was the above picture, of an animatronic Glyptodont covered in fur.
Now, I'd seen Glyptodonts before, but the reconstructions that I remember came across more as giant armadillos, as opposed to the huge beaver with a shell on its back that you see here. So I contacted Brian Switek, my favorite dinosaur blogger, to ask him which image of the Glyptodont is the correct one.
His response: They both are.

An archaeological expedition in the northeastern lowlands of Guatemala yields an amazing discovery: the "9th-century workplace of a city scribe, an unusual dwelling adorned with magnificent pictures of the king and other royals and the oldest known Maya calendar."
From Thomas Maugh's report in the Los Angeles Times, on the dig in the ruins of Xultun led by William Saturno of Boston University:
This year has been particularly controversial among some cultists because of the belief that the Maya calendar predicts a major cataclysm — perhaps the end of the world — on Dec. 21, 2012. Archaeologists know that is not true, but the new find, written on the plaster equivalent of a modern scientist's whiteboard, strongly reinforces the idea that the Maya calendar projects thousands of years into the future.
To paraphrase modern-day Maya priests I've spoken with on past travels in rural Guatemala: "Well, duh."
The findings were first reported Thursday in the journal Science. The full text of the report requires paid subscription, but a recent Science podcast covers the news, and is available here (PDF transcript or MP3 for audio).
