Hasn’t changed a bit in half a millennium

Archaeologists are digging up a Tuscan convent and have found some skeletons that might include the remains of Lisa Gherardini del Giocondo, also known as Mona Lisa. She’s still lovely after all this time.

One investigator has been going through the bones, trying to identify the dead woman, so they can apply forensic reconstruction to her skull.

Wait…why?

I mean, we already know what she looked like. I can understand general historical research on Renaissance remains, but pawing through the graveyard to find one famous person simply to reconstruct a face we’re already familiar with seems peculiarly ghoulish — nothing but a sensationalistic game. What question does this answer, what do we learn from this pointless exercise?

Fortunately, I’m not the only one who wonders about that.

But not all experts are convinced by the claims of Dr Vinceti and his team. Dr Kristina Killgrove, an anthropologist at University of North Carolina at Chapel Hill in the US, said on her blog: "Although the excavation is being carried out in a professional manner, Vinceti’s quest to dig up the ‘real’ Mona Lisa is not grounded in scientific research methodology." She added: "The news media’s breathless coverage of it threatens to signal to the public that archaeologists are frivolous with their time, energy, and research money."

Maybe, once they identify the skull, they can send it off to the Louvre and mount it on the wall next to the painting. <sarcasm>That’ll be informative.</sarcasm>

An anatomy quiz!

The Australian department of health distributed these posters to aboriginals and Torres Strait islanders to improve understanding of their bodies. I’m forced to conclude that either aboriginal peoples in the southern hemisphere are aliens with a remarkably deviant body plan, or the Australian government doesn’t give a damn.

Can you spot all the errors?

Answers:
Heart is reversed
Right kidney is not a pancreas
Ovaries are not kidneys
Stomach is not a respiratory organ
Small intestines are not a pear-shaped organ called the stomach

The poster has been withdrawn. The real mystery is whose understanding of anatomy at the health department is this bad.

Hail to the king

Man, some days I’m so embarrassed for my phylum. In this video, a bait container is lowered into murky South African waters, and you can see all the fish swirling about, quite excited by the tasty flavors, and ineffectually pecking at it (or the camera. Stupid fish.) Then the King Mollusc slithers purposefully into view, wraps around the container, fends off all the fish, and unties and escapes with the bait.

It’s settled. When I die, I want to be reincarnated as a more advanced organism — a cephalopod.

(I know, what I want and what I will get are very different things. I guess I’ll settle for being mollusc food.)

The New iOS Maps App Will Kill You

… that is, if you try to use it to navigate your way through the desert.

I won’t make a habit of just linking to the stuff I write elsewhere without expanding on it substantially for the Horde’s benefit*, but I’ve been following stories of people who die because they rely on online maps for way too long, and I don’t want to read about any of you in the paper. Like I did the Danish tourists who were looking for the U2 Joshua Tree 260 miles from where the tree actually used to be, based on an internet fan club map.

If any of you are going to have an uncomfortable time in the desert based on questionable online advice, I’d much rather it be because we set up some Pharyngula Desert 2013 kinda deal and we ran out of single-malt on day 2. Rather than that permanent thing.

So go read. And heed.

Cyanobacteria, the desert soil, and you

Cryptobiotic soil

The Palm Springs library talk last week went well: reasonable crowd given the venue, lots of good questions, and though they weren’t set up for video there’s some talk of my doing a repeat even more local and I’ll make sure we get video of that, if it happens.

One of the questions that came up was about something that was related to the topic of my talk but worthy of its whole own presentation: cryptobiotic soil crusts. I was instructed to come up with an hour-long presentation on the topic and come back. I think they may have been kidding.

Cryptobiotic soil crusts, also referred to as cryptogamic soils, or just plain “crypto,” are pretty common in arid lands that haven’t been disturbed for a while. They’re alive, as indicated by the  suffix “biotic”: living communities of half a dozen different kinds of organisms: cyanobacteria, green and brown algae, fungi, lichens, mosses and liverworts. The “crypto” part means that when conditions are less than optimal, the organisms that make up the crust can go dormant, seeming to die off — “hiding” their life. Cryptobiotic.
