The Science of Love
“Losing or ending a romantic relationship is one of the most painful losses an adult can experience,” begins the BAS (A Study Full of Acronyms) study by German and Iranian researchers. Journal of Psychiatry Research.
This is science at its most overtly romantic: electromagnetically stimulating the brains of volunteers who have suddenly experienced heartbreak. It's also science with the most acronyms: tDCS (transcranial direct current stimulation), DLPFC (dorsolateral prefrontal cortex), VLPFC (ventrolateral prefrontal cortex), LTS (love trauma syndrome).
For those who have suffered through heartbreak, here's a passage worth hearing out loud as a midnight rooftop monologue: “Thirty-six participants with love trauma syndrome were randomly assigned to three tDCS conditions (left DLPFC, right VLPFC, or sham stimulation). LTS symptoms, treatment-related outcome variables (depression, anxiety, emotion regulation, positive and negative affect), and cognitive functioning were assessed pre-intervention, immediately after intervention, and one month after the intervention.”
The evaluation showed that brain zapping “ameliorated symptoms of LTS,” according to the researchers, but they cautioned that, in terms of science in general, “there are significant gaps in the research on 'love trauma syndrome,' what exactly the symptoms are and what the diagnostic criteria are.”
Eliminates odors
Kevin Lee sees some causation in the actions of perhaps London's (and the world's) first celebrity pathologist.
He writes: “I'm a retired forensic scientist and, as you can imagine, I've been asked countless times how I deal with smells. Apart from the old-fashioned solution of smiling innocently and asking, 'Ouch, what's that?', I still have a keen sense of smell and can detect a range of odours, even when the smell of decay is very faint. I've trained myself to have a fairly neutral approach to these smells, so that although I still notice them well, after one good sniff, they're no longer an issue.”
“Recent articles [Feedback, 15 June] Sir Bernard Spilsbury, a very famous forensic scientist in the early 20th century, said that his sense of smell was extremely defective. If it was, it is more likely that this was because he was a heavy smoker, smoking around 50 cigarettes a day. It is also possible that he used the same techniques that I later used.”
A slice of life
This note from UK reader Gerald Legg depicts body parts that are living (elbow), dead (hair), nominal (leg) and sliced: “Your recent article, 'Parting the Hair' (July 20th) made me think of my time at Manchester University, where my PhD research involved a lot of microtome work using an old but still-functioning Cambridge rocking microtome. [a specialist cutting device].
“I was taught how to sharpen the blade using a glass plate and cerium dioxide. Before each use, the blade is sharpened and then tested under 40x magnification to make sure it is free of scratches. The test is to cut a hair. A sharp blade can cut a hair three times, lifting the little curled section that is still attached to the body of the hair and then cutting the hair straight through.
“There was a sharp knife in the lab, and I put my elbow against the knife and heard it cutting all the way to the bone, but I didn’t feel anything.
“I was rushed to the nearby Manchester Hospital, where I was quickly healed with just a few stitches and was able to return to the lab and continue serial sectioning with the same blade.”
Anonymous
When students make tangible contributions to science, some teachers find ways to publicly recognize who, what, and where they did it, especially when students make extraordinary sacrifices.
In the academic world, credits are limited: individual students are not identified by name.
Simple Happiness
“Simple, simple, simple” is an old rule of thumb, especially among scientists. In honor of this maxim, Feedback has created a document collection called “Simple, Simple, Simple.”
The first item in this assemblage is report It was published in the February 6, 1997 issue under the heading “The Uniquely Simple Personality of Politicians” NatureThe study suggests that a politician's personality can be summed up in just two or three numbers – in stark contrast to the five numbers psychologists claim are needed to judge the average person.
The study's authors were awarded the Ig Nobel Prize in Psychology in 2003.
