Stunningly Detailed 3D Scans of Pompeii Victims

In Italy, a group of experts appointed by the Archaeological Superintendence of Pompeii are slowly bringing the ancient tragedy of Pompeii's volcanic eruption to life, one CAT scan at a time.

Archaeologists are working side by side with computer engineers, radiologists, and orthodontists, using cutting-edge imaging technology to scan the plaster-cast remains of 86 individuals who perished when the Italian city was decimated by a volcanic eruption in 79 CE. The scans, which provide a strikingly detailed look at the remains' teeth, bones, and facial features, are teaching the researchers more about Pompeii's residents—their gender, how old they were, what they ate, and whether they were in good health.

So far, researchers have scanned about 30 individuals. They recently shared their findings, revealing humanizing 3D pictures of the bodies beneath their plaster casts. The images include the remains of a presumed family: a 4-year-old boy, who was found resting near an adult man and a woman with an infant.

Thanks to their teeth and bones, experts now know a little more about the victims’ lives—for instance, that they adhered to a diet rich in fruit and vegetables and had strong, healthy teeth thanks to fluorine in their local water source. A more sobering find: Many of them suffered severe head injuries, presumably from falling rubble during the eruption.

Although an estimated 2000 people died in Pompeii, only 1150 individuals have been discovered since the mid 19th century, when archaeologists began finding bodies buried beneath layers of hardened pumice. Their flesh had decomposed, leaving behind entire skeletons encased in the ashy residue. Researchers preserved the bodies' outlines by pouring plaster into the cavities, allowing the liquid to harden into a cast. So far, about 100 of these remains have been conserved, including skeletons from animals like a dog and a wild boar.

Twenty of the recently scanned casts are now on display at Pompeii. View photos of the research below.

Researchers Find 100-Year-Old Antarctic Fruitcake in 'Excellent Condition'

If you want a snack that really won’t go bad, consider the fruitcake. Conservationists working with artifacts from Cape Adare, Antarctica, just discovered a remarkably well-preserved fruitcake dating back a full century, according to Gizmodo.

The fruitcake dates back to Robert Falcon Scott’s disaster-plagued Terra Nova expedition, which began in 1910. Documentation proves that Scott brought tins of the same Huntley & Palmers fruitcake with him to Cape Adare, about 1700 miles south of New Zealand.

The 106-year-old fruitcake tin is rusted and its paper wrapper damaged—though still largely intact—but the cake itself “was in excellent condition,” as a press release from the New Zealand-based Antarctic Heritage Trust, whose researchers discovered the tin, describes. The release says it “looked and smelt (almost) edible,” which is a glowing review for a food that dates back to William Taft’s presidency.

Why fruitcake? “It’s an ideal high-energy food for Antarctic conditions, and is still a favorite item on modern trips to the Ice,” according to the AHT’s project manager for artifacts, Lizzie Meek. Four AHT conservators have been working to preserve almost 1500 artifacts from Cape Adare, where Norwegian explorer Carsten Borchgrevink erected the first buildings in Antarctica. (Scott’s expedition later used the same huts.) They're still standing, and the AHT’s next project will be preserving the structures.

The Cape Adare site is an Antarctic Specially Protected Area, and the trust is working under a permit that requires its conservators to return any artifacts to the huts after they’ve been restored, meaning Scott’s fruitcake will eventually go back to where it was found.

Surprisingly, this is not the first fruitcake that has stayed edible for more than a century. Fidelia Ford made a holiday fruitcake in 1878, and it’s still in the family. It’s not quite fresh, though. One of Ford’s descendants reviewed it thusly: “Not much of a taste, no, and not good.” Given that Scott’s fruitcake is set to return to Cape Adare eventually, it’s doubtful that anyone will get a taste. We’ll just have to use our imaginations.

Scientists Devise Clever Way to Test Old Manuscripts’ DNA

When encountering an obstacle, some people stop and give up, some force their way through, and others find another way around. That's what scientists in the United Kingdom have done with a delicate manuscript from the Dark Ages. Barred from taking parchment samples, the resourceful researchers instead analyzed the eraser crumbs left behind after archivists cleaned the paper. They describe their findings in an article on the prepress server bioRxiv.

Co-author and archaeologist Matthew Collins of the University of York did not start out a manuscript man. Collins had been trying to extract DNA from animal bones unearthed at a Viking settlement to learn more about the culture's use of livestock. But the bones had decayed too far to offer much in the way of genetic material. "You can imagine the frustration," Collins said in an interview with The Atlantic.

Then he realized that animal remains can be more than just bones. There are skins, too—and those, at least, we've taken some pains to preserve. At least the ones we've written on.

"You look at [archive] shelves," Collins said, "and every one of them has a skin of an animal with a date written on it."

Collins's excitement at discovering this untapped bounty of data was soon tempered when he and his collaborator, biochemist Sarah Fiddyment, learned that sampling the manuscripts was completely off-limits.

But they weren't about to give up that easily. Fiddyment spent weeks following the conservators as they worked with the fragile animal-skin paper, learning their process and watching for possible openings. Finally, she saw it: eraser crumbs.

Conservators routinely use PVC erasers to lift stains, grime, and damage from historic documents. The friction created by gently rubbing the eraser against the paper creates an electric charge that pulls in molecules of dirt and oil. And probably other things, too, Fiddyment thought.

Fiddyment, Collins, and their colleagues began collecting eraser crumbs from manuscript conservators around the world. They analyzed each document's chemical makeup and were even able to compare proteins to identify the livestock species responsible for the skin.

The next step was to look at the DNA itself. The researchers turned to the York Gospels, a leatherbound Bible with pages dating back to the year 990. By collecting another tiny pile of eraser crumbs from cleanup of eight pages, they were able to collect enough of a sample to run thorough DNA tests.

Those pages had quite a lot to say about their creation and history. The tests revealed 1000-year-old genetic material from the cows and sheep that gave the book its parchment pages. Remarkably, the DNA was so intact that the scientists could identify the cows' ancestry (something close to our modern-day Norwegian reds and Holsteins) and sex (mostly female).

The pages also contained human DNA and even bacteria, most likely from the hands and saliva of the people who made, wrote, and used the book.

Speaking to The Atlantic, parchment expert Bruce Holsinger of the University of Virginia called the findings "an exciting breakthrough."
