The Weird Family History of Iceland

Iceland has a population of 332,529 that for hundreds of years has been largely isolated from the rest of the world. Inbreeding is a constant concern due to the country’s small size, and the migration of most of the population into the capital city. Luckily, the country has been literate since its founding, and because of its small population and isolation, we have marriage and birth records pretty much since the founding of the island. Everyone's family tree is known. It is pretty neat -- every Icelander today can trace their heritage back to which founding settlers they come from.

And to help prevent inbreeding today, an app was developed: Islendiga-App (English: App of Icelanders). The whole giant Icelandic family tree is on the app, and people can check to see if they are related. Its slogan is “Bump the app before you bump in bed.”

What Is An Ice Age?

When you read that, an image probably came to mind: giant glaciers, people huddling for warmth, maybe a giant woolly mammoth or two. The problem with that definition of "Ice Age" is it defines what life is like now on Earth as "normal" and giant glaciers over the north and south pole as "abnormal." But is that true? Are we, in fact, living in a period of relative coolness? Is right now an "abnormal" Earth?

A better description of an ice age would be that it’s a long stretch of time in which both the atmosphere and the planet’s surface have a low temperature, resulting in the presence of polar ice sheets and mountainous glaciers. An Ice Age can last for several million years. Within the Ice Age period, the Earth isn't uniformly covered in snow. There are periods of glaciation, characterized by ice sheet and glacier expansion over the face of the planet, and interglacial periods, where we would have an interval of several thousand years of warmer temperatures and receding ice. Turns out just the presence of ice caps on the north and south pole is abnormal! What we currently live in is an "interglacial period" in the middle of an Ice Age!

Dice Have Gotten More Fair Since Ancient Times

A survey of cube-shaped dice dating back to the Roman era finds that they were not designed to have an equal chance of landing on different numbers until the Renaissance, according to researchers from UC Davis and the American Museum of Natural History. Roman-era dice, the researchers found, were a mess when it came to shape. They were made from a variety of materials, such as metal, bone and clay, and no two were shaped entirely alike. Many were visibly lumpy and lopsided, with the 1 and 6 on opposite sides that were more likely to roll up. In the Dark Ages after the fall of the Western Roman Empire, between 400 CE and 1100 CE, dice seem to have grown rare. Relatively few have been found from this period. Dice reemerged in the Middle Ages, and at that point were a little more regular in shape. But they still weren't fair -- anyone playing dice would have had slightly higher chances of getting certain numbers, depending on how uneven the dice were made.

The researchers suggest that the popularization of "scientific" thinking may have helped dice rolls become near-chance during the Renaissance. "People like Galileo and Blaise Pascal were developing ideas about chance and probability, and we know from written records in some cases they were actually consulting with gamblers," Jelmer Eerkens of UC Davis said. "We think users of dice also adopted new ideas about fairness, and chance or probability in games."

Underwater Route Between Prehistoric Cenotes Found In Mexico

Researchers from Mexico’s National Institute of Anthropology and History have discovered a route through underwater limestone caves connecting the Sac Actun cenote and the Dos Ojos cenote. Maya pottery, human bones, and the bones of elephant-like creatures, giant sloths, bears, tigers, and extinct species of horses, all likely from around the end of the last Ice Age, have been found in the tunnel-like caves. Exploring them and finding artifacts can be difficult, though: the underwater caves range in width from 400 feet to just three feet.

Columbus was Obsessed with Jerusalem

Christopher Columbus was interested in reaching Asia, and believed he had, as we all know. But did you know that his original reason for wanting to open a new trade route to the rich East was to pay for a military campaign to capture Jerusalem? Never mind that the holy city had been in Muslim hands since 1187 CE -- about 300 years by the time Columbus was born -- and Christian Europe had long since given up on crusades to the Middle East.

Once the New World was reached, Columbus kept his eye on the prize. He reported that there was so much treasure in this "Asia" he had found, that within seven years the Spanish crown could raise enough money for 5,000 cavalry and 50,000 footsoldiers, and use them to conquer Jerusalem. Sadly for Columbus' lofty religious visions, the Spanish crown was uninterested in conquering Jerusalem, which is on the wrong side of the Mediterranean from Spain.

Major Pre-Columbian Turquoise Producer Determined

Canyon Creek in eastern Arizona was one of the turquoise sources exploited by pre-Columbian indigenous groups, but it has long been considered insignificant. A new study of the area, however, has shown that the mines were actually a major supplier of the bluish-green mineral during the 1200s and 1300s CE, when turquoise was exported to sites as far as 80 miles away. Lead isotope analysis of samples indicates that Canyon Creek turquoise is unique, making it distinguishable from other sources in the Southwest, and allowing modern archaeologists to trace where Canyon Creek turquoise was exported to.

Where Do Popes Come From?

  A map of where, in the world, popes have been born. Note that they placed each pope in the country he would be born in, if he was born today. Three popes were born in modern-day Tunisia, sure, but that was back in the Roman Empire. Those ancient "Tunisian" popes would have called it the province of "Africa" and it included eastern Algeria and northern Libya, as well as Tunisia.

Native Americans knew about rubber for centuries (at least) before Europeans stumbled onto the Americas. They made balls for children, and waterproof shoes and bottles with the weird milky white substance that bled from certain trees -- what we call latex today.
