Woman uses her super sense of smell to help scientists detect Parkinson's in minutes

Joy Milne first smelled the disease on her husband 10 years before his diagnosis.

There is currently no definitive test to detect Parkinson's.

We don’t always choose our gifts. Joy Milne’s superpower, one she inherited from her mother’s side of the family, was having a highly acute sense of smell.

Milne might have never used her olfactory talent as a force for good, had it not been for her late husband, Les Milne.

According to NPR, Les and Joy met in their teens and it was love at first sniff. "He had a lovely male musk smell. He really did," she told NPR.

After many years of a happy marriage, Joy noticed her husband, then in his 30s, had developed an “overpowering sort of nasty yeast smell.” The running joke-slash-complaint was that Les “wasn’t washing enough.”

Eventually Les’ scent wouldn’t be the only thing to change. Joy told NPR that her once funny, thoughtful husband completely transformed, becoming “moody,” irritable and even aggressive. He wouldn’t receive a proper Parkinson’s diagnosis until the age of 45.

Joy didn’t suspect that she could somehow detect the disease until going with Les to a Parkinson’s support group and noticing that the same distinctive smell seemed to fill the room. After sharing the discovery with her husband, she knew she had to take action.

Joy began working with researchers at University of Edinburgh and through a series of experiments confirmed that she could sniff out Parkinson’s with flawless accuracy. Now scientists have created a breakthrough method of detection based on Joy’s special ability.


This new test works in mere minutes.


Under the belief that Parkinson’s affects a person’s odor due to a chemical change in sebum, or skin oil, doctors simply run a cotton ball along the back of the neck, then identify specific molecules linked to the neurological condition. The BBC reported that the skin-swab test is 95% accurate under laboratory conditions.

Though this medical advancement is still in its early stages, the discovery is promising. There is currently no definitive test to get a Parkinson’s diagnosis and, as Joy explained to Sky News, it is often not identified until patients have “over 50% of neuronal damage.”

Les died in 2015 at 65. An earlier diagnosis might have provided the opportunity to improve his lifestyle, which could possibly have offset symptoms. “It has been found that exercise and change of diet can make a phenomenal difference,” Joy told The Guardian.

She also recalled to BBC News that it would have meant having an explanation for the mood swings, not to mention traveling, spending more time with family … making the most out of what time was left. That perhaps is the biggest saving grace an early diagnosis could offer.

Les’ final wish before he passed was for Joy to continue using her gift, assuring that "it will make a difference." Joy is keeping that promise and currently extending her “super smeller” power to help smell other diseases like cancer and tuberculosis (TB).

While she notes that her superpower does make outings like shopping a “curse sometimes,” she also sees it as a “benefit” allowing her to help others.

One moment in history shot Tracy Chapman to music stardom. Watch it now.

She captivated millions with nothing but her guitar and an iconic voice.

Imagine being in the crowd and hearing "Fast Car" for the first time

While a catchy hook might make a song go viral, very few songs create such a unifying impact that they achieve timeless resonance. Tracy Chapman’s “Fast Car” is one of those songs.

So much courage and raw honesty is packed into the lyrics, only to be elevated by Chapman’s signature androgynous and soulful voice. Imagine being in the crowd and seeing her as a relatively unknown talent and hearing that song for the first time. Would you instantly recognize that you were witnessing a pivotal moment in musical history?

For concert goers at Wembley Stadium in the late 80s, this was the scenario.

Tater Tots, fresh out of the oven.

It’s hard to imagine growing up in America without Tater Tots. They are one of the most popular kiddie foods, right up there with chicken nuggets, peanut butter and jelly sandwiches and macaroni and cheese. The funny thing is the only reason Tater Tots exist is that their creators needed something to do with leftover food waste.

The Tater Tot is the brainchild of two Mormon brothers, F. Nephi and Golden Grigg, who started a factory on the Oregon-Idaho border that they appropriately named Ore-Ida. The brothers started the factory in 1951 after being convinced that frozen foods were the next big thing.

According to Eater, between 1945 and 1946, Americans bought 800 million pounds of frozen food.

Finally, someone explains why we all need subtitles

It seems everyone needs subtitles nowadays in order to "hear" the television. This is something that has become more common over the past decade and it's caused people to question if their hearing is going bad or if perhaps actors have gotten lazy with enunciation.

So if you've been wondering if it's just you who needs subtitles in order to watch the latest marathon-worthy show, worry no more. Vox video producer Edward Vega interviewed dialogue editor Austin Olivia Kendrick to get to the bottom of why we can't seem to make out what the actors are saying anymore. It turns out it's technology's fault, and to get to how we got here, Vega and Kendrick took us back in time.

They first explained that way back when movies were first moving from silent film to spoken dialogue, actors had to enunciate and project loudly while speaking directly into a large microphone. If they spoke and moved like actors do today, it would sound almost as if someone were giving a drive-by soliloquy while circling the block. You'd only hear every other sentence or two.

Parents, maybe give yourselves a break

For every grain of sand on all the world’s beaches, for every star in the known universe…there is a piece well intentioned, but possibly stress-inducing parenting advice.

Whether it’s the astounding amount of hidden dangers that parents might be unwittingly exposing their child to, or the myriad ways they might be missing on maximizing every moment of interaction, the internet is teeming with so much information that it can be impossible for parents to feel like they’re doing enough to protect and nurture their kids.

However, developmental scientist and mom Dorsa Amir has a bit of “anti-parenting advice” that help parents worry a little less about how they’re measuring up.

First and foremost—not everything has to be a learning opportunity. Honestly, this wisdom also applies to adults who feel the need to be consistently productive…raises hand while doing taxes and listening to a podcast on personal development

A guy with road rage screaming out of his car.

A psychologist who’s an expert in narcissism has released a telling video that reveals one of the red flags of the disorder, being an erratic driver.

"Most people, when they tell the story backwards of a narcissistic relationship, are able to see the red flags very clearly,” Dr. Ramani said in her video. “However, seeing them forwards isn't hard. But if you see them too late, it means you've already been through the narcissistic relationship, you're devastated and have likely wasted a lot of time."

Dr. Ramani Durvasula is a licensed clinical psychologist in Los Angeles, Professor Emerita of Psychology at California State University and author of several books, including “Should I Stay or Should I Go: Surviving A Relationship with a Narcissist.”

Man hailed 'Highway Hero' for running across four lanes of traffic

Holy cow, Bat Man! You're always supposed to be aware of other vehicles when you're driving but what do you do when you notice someone has lost consciousness while speeding down the highway?

It's a scenario that no one wants to see play out, but for Adolfo Molina, the scenario became reality and he didn't hesitate to spring into action. Molina was driving down the highway when he spotted a woman in a blue car who lost consciousness as her car careened down the shoulder of the highway. The concerned driver quickly pulled over in order to attempt to rescue the woman.

But there was a problem, he had to cross four lanes of traffic on the highway just to make it to the woman's still moving car. That obstacle didn't stop him. Molina sprinted across the highway, crossing right in front of a black pick up truck before running at full speed to attempt to open the woman's door and stop her car.
