New way to detect Parkinson’s has already passed the sniff test
We humans aren’t generally known for our superpowers, but a woman from Scotland may just be the Smelling Superhero. Not only was she able to literally smell Parkinson’s disease (PD) on her husband 12 years before his diagnosis; she is also the reason that scientists have found a new way to test for PD.

Joy Milne, a retired nurse, told the BBC that her husband “had this musty rather unpleasant smell especially round his shoulders and the back of his neck and his skin had definitely changed.” She put two and two together after he had been diagnosed with PD and she came in contact with others with the same scent at a support group.
Researchers at the University of Manchester, working with Ms. Milne, have now created a skin test that uses mass spectroscopy to analyze a sample of the patient’s sebum in just 3 minutes and is 95% accurate. They tested 79 people with Parkinson’s and 71 without using this method and found “specific compounds unique to PD sebum samples when compared to healthy controls. Furthermore, we have identified two classes of lipids, namely, triacylglycerides and diglycerides, as components of human sebum that are significantly differentially expressed in PD,” they said in JACS Au.
This test could be available to general physicians within 2 years, which would provide new opportunities to the people who are waiting in line for neurologic consults. Ms. Milne’s husband passed away in 2015, but her courageous help and amazing nasal abilities may help millions down the line.
The power of flirting
It’s a common office stereotype: Women flirt with the boss to get ahead in the workplace, while men in power sexually harass women in subordinate positions. Nobody ever suspects the guys in the cubicles. A recent study takes a different look and paints a different picture.

The investigators conducted multiple online and lab experiments in how social sexual identity drives behavior in a workplace setting in relation to job placement. They found that it was most often men in lower-power positions who are insecure about their roles who initiate social sexual behavior, even though they know it’s offensive. Why? Power.
They randomly paired over 200 undergraduate students in a male/female fashion, placed them in subordinate and boss-like roles, and asked them to choose from a series of social sexual questions they wanted to ask their teammate. Male participants who were placed in subordinate positions to a female boss chose social sexual questions more often than did male bosses, female subordinates, and female bosses.
So what does this say about the threat of workplace harassment? The researchers found that men and women differ in their strategy for flirtation. For men, it’s a way to gain more power. But problems arise when they rationalize their behavior with a character trait like being a “big flirt.”
“When we take on that identity, it leads to certain behavioral patterns that reinforce the identity. And then, people use that identity as an excuse,” lead author Laura Kray of the University of California, Berkeley, said in a statement from the school.
The researchers make a point to note that the study isn’t about whether flirting is good or bad, nor are they suggesting that people in powerful positions don’t sexually harass underlings. It’s meant to provide insight to improve corporate sexual harassment training. A comment or conversation held in jest could potentially be a warning sign for future behavior.
