You are getting pregnant ... very pregnant

If you thought hypnosis was just about making people quack like a duck when you snap your fingers, think again. Hypnosis is being used more and more frequently to help people get through stressful and painful ordeals -- like surgery and giving birth. You heard right: it's called hypnobirthing, and according to British doctors, the technique produces "really chilled babies." (Which is to say, cool, Daddy-o babies, not hypothermic ones.) What's more, the mothers -- who learn to induce self-hypnosis rather than having someone dangle a watch in front of their eyes and count backwards -- often sail through the birthing process in only a few hours, with fewer complications than usual -- and without so much as aspirin. One mother, who describes herself as "a worrier" who had been excessively nervous about giving birth, describes her experience with hypnobirthing this way: "I just breathed her out without drugs it was just great and I could not have wished for anything better."

Meanwhile, on our side of the pond, a recent study indicates that hypnosis can help women going through breast cancer surgery. 200 women were recruited to undergo just fifteen minutes of hypnosis before surgery -- during which they were instructed to relax, and given pleasant mental images to concentrate on -- the majority of which reported markedly fewer side effects, pain, nausea or emotional distress after the operation.

If that wasn't enough, doctors are also beginning to use hypnosis treat conditions as varied as hay fever, asthma, eczema, migraine headaches -- and even to aid in the success rate of in-vitro fertilization (studies in Israel have found that hypnotized mothers-in-hoping have twice the chance of becoming pregnant as those not hypnotized).

All that sounds great, but selfish as I am I find myself wondering if I couldn't use hypnosis to help get through more mundane trials, like having my teeth cleaned at the dentist or getting through a slower-than-molasses rush hour commute.

Have any of you ever been hypnotized? Did it work?

New Program Trains Dogs to Sniff Out Art Smugglers

Soon, the dogs you see sniffing out contraband at airports may not be searching for drugs or smuggled Spanish ham. They might be looking for stolen treasures.

K-9 Artifact Finders, a new collaboration between New Hampshire-based cultural heritage law firm Red Arch and the University of Pennsylvania, is training dogs to root out stolen antiquities looted from archaeological sites and museums. The dogs would be stopping them at borders before the items can be sold elsewhere on the black market.

The illegal antiquities trade nets more than $3 billion per year around the world, and trafficking hits countries dealing with ongoing conflict, like Syria and Iraq today, particularly hard. By one estimate, around half a million artifacts were stolen from museums and archaeological sites throughout Iraq between 2003 and 2005 alone. (Famously, the craft-supply chain Hobby Lobby was fined $3 million in 2017 for buying thousands of ancient artifacts looted from Iraq.) In Syria, the Islamic State has been known to loot and sell ancient artifacts including statues, jewelry, and art to fund its operations.

But the problem spans across the world. Between 2007 and 2016, U.S. Customs and Border Control discovered more than 7800 cultural artifacts in the U.S. looted from 30 different countries.

K-9 Artifact Finders is the brainchild of Rick St. Hilaire, the executive director of Red Arch. His non-profit firm researches cultural heritage property law and preservation policy, including studying archaeological site looting and antiquities trafficking. Back in 2015, St. Hilaire was reading an article about a working dog trained to sniff out electronics that was able to find USB drives, SD cards, and other data storage devices. He wondered, if dogs could be trained to identify the scents of inorganic materials that make up electronics, could they be trained to sniff out ancient pottery?

To find out, St. Hilaire tells Mental Floss, he contacted the Penn Vet Working Dog Center, a research and training center for detection dogs. In December 2017, Red Arch, the Working Dog Center, and the Penn Museum (which is providing the artifacts to train the dogs) launched K-9 Artifact Finders, and in late January 2018, the five dogs selected for the project began their training, starting with learning the distinct smell of ancient pottery.

“Our theory is, it is a porous material that’s going to have a lot more odor than, say, a metal,” says Cindy Otto, the executive director of the Penn Vet Working Dog Center and the project’s principal investigator.

As you might imagine, museum curators may not be keen on exposing fragile ancient materials to four Labrador retrievers and a German shepherd, and the Working Dog Center didn’t want to take any risks with the Penn Museum’s priceless artifacts. So instead of letting the dogs have free rein to sniff the materials themselves, the project is using cotton balls. The researchers seal the artifacts (broken shards of Syrian pottery) in airtight bags with a cotton ball for 72 hours, then ask the dogs to find the cotton balls in the lab. They’re being trained to disregard the smell of the cotton ball itself, the smell of the bag it was stored in, and ideally, the smell of modern-day pottery, eventually being able to zero in on the smell that distinguishes ancient pottery specifically.

“The dogs are responding well,” Otto tells Mental Floss, explaining that the training program is at the stage of "exposing them to the odor and having them recognize it.”

The dogs involved in the project were chosen for their calm-but-curious demeanors and sensitive noses (one also works as a drug-detection dog when she’s not training on pottery). They had to be motivated enough to want to hunt down the cotton balls, but not aggressive or easily distracted.

Right now, the dogs train three days a week, and will continue to work on their pottery-detection skills for the first stage of the project, which the researchers expect will last for the next nine months. Depending on how the first phase of the training goes, the researchers hope to be able to then take the dogs out into the field to see if they can find the odor of ancient pottery in real-life situations, like in suitcases, rather than in a laboratory setting. Eventually, they also hope to train the dogs on other types of objects, and perhaps even pinpoint the chemical signatures that make artifacts smell distinct.

Pottery-sniffing dogs won’t be showing up at airport customs or on shipping docks soon, but one day, they could be as common as drug-sniffing canines. If dogs can detect low blood sugar or find a tiny USB drive hidden in a house, surely they can figure out if you’re smuggling a sculpture made thousands of years ago in your suitcase.
