The Enduring Mystery of the Antikythera Mechanism

In 1900, a team of sponge divers submerged themselves into the sea off the island of Antikythera between mainland Greece and Crete and emerged with a curious find. Exploring a Roman shipwreck, they brought up a bronze-and-wood object that defied description. It looked like a clock, but not quite; it resembled a gear or wheel, but held no hints that it was once attached to any mode of transport.

The Antikythera mechanism, as it came to be known, was largely ignored for the next half-century, as researchers were preoccupied with the other artifacts found in the shipwreck and lacked the tools to see through its corroded exterior. But in recent decades, the importance and capability of the Greek-born device thought to date to the 1st or 2nd century BCE has slowly been unspooling. Depending on how you define the term, it may be the world’s first computer.

Although investigation into the strange box began when it was first retrieved, it wasn’t until researchers began using radiographs to examine its inner workings that the true nature of the Antikythera mechanism was discovered. Inside, they found 30 bronze gears that was operated by a hand crank. About the size of a shoebox, it acted as an astronomical calendar, predicting the cycles of the solar system in the coming decades. Lunar months and eclipses could also be anticipated. Greek zodiac signs and Egyptian calendar dates appear on the front. By turning the dial to one of the 365 days on its face, the user could anticipate the exact position of the Sun and Moon.

While X-rays could provide some basic structural information to investigators, microfocus X-rays, originally developed to find tiny fractures in turbine blades, were also put to use, revealing faded inscriptions that haven’t been visible for thousands of years. Tiny letters 1.2 millimeters tall told users what they might see when operating it.

There’s still much left to learn about the Antikythera mechanism. No one is quite sure who made it or for what purpose, although it’s possible a school may have been the beneficiary of its results. It’s also possible the Antikythera mechanism was devised to tell fortunes, as it provided information about eclipses that were associated with good and bad omens.

The remains of the Antikythera mechanism are housed in the National Archaeological Museum in Athens, Greece, along with sculptures and other relics from the dive. With the site of the wreck still being scouted, it’s possible more answers about this strange, impeccably designed machine may still be lurking at the bottom of the sea.

9-Year-Old Boy Trips Over the Bones of a Long-Extinct Elephant Relative

A 9-year-old boy quite literally stumbled across a new paleontological discovery when he tripped over a giant skull while hiking in Las Cruces, New Mexico in November 2016. As The New York Times reports, the fossilized bones have been identified as the million-year-old remains of a Stegomastodon, a long-extinct distant relative of the modern elephant.

It all began with a game of chase: Jude Sparks, now 10, was running from his younger brothers when he tumbled face-first over what appeared to be a giant tusk. "My face landed next to the bottom jaw," Sparks told ABC news affiliate KVIA-TV. "I look farther up and there was another tusk."

Sparks's parents thought it looked like an elephant skull; his brother, a cow skull. As for Jude himself, he eyed the oddly shaped bones, and "just knew it was not something that you usually find," he later told the Times.

The Sparks didn't dig up the bones, but they did take a cell phone picture. Later, they compared the snapshot to elephant skulls, but they weren't 100 percent identical. So to solve the mystery once and for all, the family sought the opinion of Peter Houde, a biology professor at New Mexico State University.

Houde instantly recognized the skull as that of a Stegomastodon, a creature that belonged to the animal family Gomphotheres and is a distant cousin of ancient mammoths and modern elephants. Stegomastodons roamed the Earth in the past few million years, and may have been hunted by early humans. This particular specimen is at least 1.2 million years old. Theories for the Stegomastodon's extinction include climate change or the arrival of mammoths, which may have led to a competition for food resources, according to National Geographic.

Mammoth fossils are relatively common across the western portion of North America, but only a couple hundred Stegomastadons have been found throughout the world. The Sparks had serendipity on their side, as they visited the site right after heavy rains had exposed the Stegomastodon skull.

Together, Houde and the Sparks family reburied the skull and sought permission from the landowner to excavate the find. Once they obtained a team, a permit, and funding, they got to work and dug up the skull in May.

"All of the protein is gone from these fossils, and the bone is very, very brittle and fragile," Houde told KVIA. "And as soon as the sediment is taken away from around it, it just falls apart completely on its own. So we have to use preservatives to stabilize it before we remove the sediment around it. And then build plaster and wooden casing around it to remove it safely. It's a big job."

The Stegomastodon will likely go on display at New Mexico State University, providing students, faculty, and visitors alike with an up-close view of the rare fossil.

Melting Glacier Reveals Bodies of Swiss Couple Missing Since 1942

On August 15, 1942, Marcelin and Francine Dumoulin ventured to the meadow above their house in the Swiss Alps to milk their cows. What should have been business as usual turned into a harrowing missing-persons case when the married couple never returned. Now, nearly 75 years later, two frozen bodies that likely belonged to Marcelin and Francine have been found in the dwindling Tsanfleuron glacier near their former home, Reuters reports.

An employee at the Les Diablerets resort in Switzerland's Valais canton saw the remains near a ski lift earlier in July. The bodies, one male and female, were perfectly preserved down to their belongings and 1940s attire. Experts believe the couple perished after falling into a crevasse. Like other Alpine glaciers, the Tsanfleuron glacier has been hit hard by rising temperatures associated with climate change. The glacier finally revealed the missing bodies this summer after years of receding.

When Marcelin and Francine vanished, they left behind seven children who never gave up hope of finding them. Seventy-nine-year-old Marceline Udry-Dumoulin, the couple’s youngest child, told a local newspaper the discovery brings her a "deep sense of calm."

The bodies will now undergo DNA testing to verify their identities. Once that's taken care of, Udry-Dumoulin plans to give her parents "the funeral they deserved."
