Can a Smartphone App Help Save a Dying Language?

By Carrie Arnold | September 23, 2016 4:07 pm
About half of the world’s languages are expected to disappear by 2100 if nothing is done to stop their decline. To counteract this trend, some tribes are using new technologies to revive their languages. Joshua Hinson of the Chickasaw Nation is leading the effort to revive the language of his ancestors.

Joshua Hinson’s first biological son was born in 2000. His son’s birth marked the start of the sixth generation that would grow up speaking English instead of Chickasaw, which was the primary language his ancestors had spoken for hundreds of years. Hinson was born in Memphis, Tennessee, and grew up in Texas. Other than a small handful of words, he knew almost nothing about his ancestral language—formally known as Chikashshanompa’. Hinson had a few pangs of sadness over the years about what was lost, but it didn’t really affect him—until his son was born.

As he counted the 10 tiny fingers and 10 tiny toes of his firstborn child, Hinson realized he had nothing to teach his son about his Native American roots. The only thing he had to pass on was his tribal citizenship card. Hinson wanted to bequeath more than just a piece of paper; he wanted his son to be a part of Chickasaw culture. He recognized that the most direct way to understand his culture was to speak the language. But to make that happen, Hinson had to start with himself. Read More

Taking Pangolin Off the Menu

When acclaimed conservation photographer Suzi Eszterhas settled in for the evening, she didn’t know what to expect. She seldom does when trying to photograph elusive, nocturnal creatures. But circumstances on this particular night were unusual. She was sitting in an enclosure—albeit a naturalistic one—and although she knew her photographic subjects couldn’t flee, she thought it was quite possible she might spend the entire night being riddled by biting ants without capturing a single shot.

Is It Neander-TAL or Neander-THAL?

Here’s the deal: you can write or say Neanderthal or Neandertal, but you should only write Homo neanderthalensis and say “Homo neander-TAL-ensis”.

I promise that will make sense by the end of this.

The name comes from Neander Valley, Germany, where the first recognized Neanderthal fossil was found in 1856 (other Neanderthal bones had been discovered earlier, but people didn’t know what to make of them). Read More

Fecal Feasts Bring Earwig Families Together

A steaming bowl of fresh feces isn’t a meal that will bring the family together over the holidays. But for many animals, fecal consumption is a way of life.

The technical term for eating poo is coprophagy, from the Greek kopros for “dung”, and phagein, “to eat”. Though we most commonly associate coprophagy with domestic dogs, many other animals are known to indulge.

Rabbits re-ingest their own droppings to extract extra nutrients; dung beetles have gone a step further and built a specialized diet around balls of manure; growth of American bullfrog tadpoles is enhanced by access to intestinal output; and consumption of fecal matter helps mediate the exchange of essential gut fauna in mice.

Lost or Found? A Stick Chart From the Marshall Islands

In a recent blog post, I focused on the Global Positioning System (GPS) and mused on how we ever got along without high-tech navigational aids. GPS units became common in cars and phones only in the last 15 years or so.

I remember when a road trip required a stop at the local American Automobile Association office to gather free maps of the planned route. Likewise, I remember when well-traveled road warriors had at least one dog-eared copy of a Rand McNally Road Atlas in their cars. Those days are gone, and I miss them. Read More

From Jet Fuel to Medicine, Tobacco Growers Turn a New Leaf

It is notorious for its role in the expansion and continuation of American slavery, and for its adverse health effects. The latter includes cardiovascular disease and various cancers, including lung cancer, the most common malignancy, underlying millions of deaths each year.

Health officials, attorneys, and activists have spent decades targeting its industrial cultivators in an effort to limit its advertising and sale, particularly to minors. Read More

What We’re Learning from the World’s Oldest Calculator

When we talk of the history of computers, most of us will refer to the evolution of the modern digital desktop PC, charting the decades-long developments by the likes of Apple and Microsoft. What many don’t consider, however, is that computers have been around much longer. In fact, they date back millennia, to a time when they were analogue creations.

Today, the world’s oldest known “computer” is the Antikythera mechanism, a severely corroded bronze artifact which was found at the beginning of the 20th Century, in the remains of a shipwreck near the Mediterranean island of Antikythera. It wasn’t until the 1970s that the importance of the Antikythera mechanism was discovered, when radiography revealed that the device is in fact a complex mechanism of at least 30 gear wheels.

Extinction Looms for Easter Island’s Only Remaining Native Species

On Easter Island, isolated in the middle of the vast Pacific Ocean, ten species of near microscopic insects are all that remain of the island’s native species — at least for now.

Hidden in volcanic caves that dot the island, the endemic insects of Rapa Nui eke out an existence in an increasingly imperiled habitat. Their ancestral homes, fragile gardens of moss and ferns, are endangered by tourists flooding into the tiny island, and hordes of invasive species threaten to crowd them out. The island may have been immortalized by its iconic Moai, monolithic stone statues standing some 40 feet tall, but its most important inhabitants are almost too small to be seen. Read More

Blame Your Subpar Fitness on That Neanderthal DNA

Most of us harbor about 2 percent Neanderthal DNA, inherited when our ancestors bred with Neanderthals more than 50,000 years ago. This was revealed back in 2010, when geneticists salvaged enough fragments of ancient DNA from Neanderthal bones to piece together a full genome. The discovery squelched a longstanding debate over whether Neanderthals and modern humans met — they did — and mated — oh yeah.

But why do we only have 2 percent Neanderthal ancestry? And what are the effects of that Neanderthal DNA on living humans? And why did our ancestors survive and Neanderthals go extinct? We’ve attributed our supremacy to bigger brains, better diets and advanced technology, but there may be a subtler, less flattering explanation for our evolutionary success. Read More

Could Goats or Cows Claim the Title of ‘Man’s Best Friend’?

Since the evolution of dogs from wolves tens of thousands of years ago, they have been selectively bred for various roles as guards, hunters, workers and companions. But dogs are not the only animal humans have domesticated, which suggests that although dogs get all the attention, there’s reason to argue other species could also deserve the title of “man’s best friend”.

Anthrozoology, the study of human-animal relationships, has established that dogs demonstrate complex communication with humans. Charles Darwin thought that dogs experienced love, but it was only in 2015 that Japanese scientists demonstrated what we all intuitively knew. Miho Nagasawa and colleagues sprayed the “love hormone” oxytocin up dogs’ noses, measured the loving gaze between dog and human, and then measured the oxytocin levels in the humans’ urine, finding them to be higher. Rest assured, dog owners, that science has verified your bond with your faithful hound. Read More
