Vladimir Nabokov Talks Synesthesia

You’ve probably heard of synesthesia, the condition that makes people involuntarily associate something with a sense that wouldn’t normally be associated otherwise. For instance, some synesthetes report that the word “blue” tastes inky, or find that an E sharp is always chartreuse.

Lolita author Vladimir Nabokov had grapheme-color synesthesia, which is when people see specific letters in specific colors—and we’re not just talking when they’re reading a Richard Scarry book. His way with words is legendary, of course, so it’s no surprise that his description of how he saw letters was rather fascinating.

“It's called color hearing,” Nabokov told the BBC in 1962. “Perhaps one in a thousand has that. But I'm told by psychologists that most children have it, that later they lose that aptitude when they are told by stupid parents that it's all nonsense, an A isn't black, a B isn't brown—now don't be absurd.”

When the interviewer asked what color his own initials were, Nabokov replied that the “V is a kind of pale, transparent pink: I think it's called, technically, quartz pink: this is one of the closest colors that I can connect with the V. And the N, on the other hand, is a greyish-yellowish oatmeal color.”

What’s more is that Nabokov “heard” different colors in different languages:

“The long "a" of the English alphabet has for me the tint of weathered wood, but a French "a" evokes polished ebony. This black group also includes hard "g" (vulcanized rubber) and "r" (a sooty rag being ripped). Oatmeal "n", noodle-limp "l", and the ivory-backed hand mirror of an "o" take care of the whites. I am puzzled by my French "on" which I see as the brimming tension-surface of alcohol in a small glass.”

Oddly—though maybe not that odd, as it’s been estimated that 1 in 23 people have some form of the condition—his wife, Véra, also had synesthesia. So did their son, which is how they discovered this interesting tidbit:

“My wife has this gift of seeing letters in color, too, but her colors are completely different. There are, perhaps, two or three letters where we coincide, but otherwise the colors are quite different. It turned out, we discovered one day, that my son, who was a little boy at the time—I think he was ten or eleven—sees letters in colors, too. Quite naturally he would say, "Oh, this isn't that color, this is this color," and so on. Then we asked him to list his colors and we discovered that in one case, one letter which he sees as purple, or perhaps mauve, is pink to me and blue to my wife. This is the letter M. So the combination of pink and blue makes lilac in his case. Which is as if genes were painting in aquarelle.”

No doubt the way he saw letters colored the way he wrote—quite beautifully, obviously.

Whale Sharks Can Live for More Than a Century, Study Finds

Some whale sharks alive today have been swimming around since the Gilded Age. The animals—the largest fish in the ocean—can live as long as 130 years, according to a new study in the journal Marine and Freshwater Research. To give you an idea of how long that is, in 1888, Grover Cleveland was finishing up his first presidential term, Thomas Edison had just started selling his first light bulbs, and the U.S. only had 38 states.

To determine whale sharks' longevity, researchers from the Nova Southeastern University in Florida and the Maldives Whale Shark Research Program tracked male sharks around South Ari Atoll in the Maldives over the course of 10 years, calculating their sizes as they came back to the area over and over again. The scientists identified sharks that returned to the atoll every few years by their distinctive spot patterns, estimating their body lengths with lasers, tape, and visually to try to get the most accurate idea of their sizes.

Using these measurements and data on whale shark growth patterns, the researchers were able to determine that male whale sharks tend to reach maturity around 25 years old and live until they’re about 130 years old. During those decades, they reach an average length of 61.7 feet—about as long as a bowling lane.

While whale sharks are known as gentle giants, they’re difficult to study, and scientists still don’t know a ton about them. They’re considered endangered, making any information we can gather about them important. And this is the first time scientists have been able to accurately measure live, swimming whale sharks.

“Up to now, such aging and growth research has required obtaining vertebrae from dead whale sharks and counting growth rings, analogous to counting tree rings, to determine age,” first author Cameron Perry said in a press statement. ”Our work shows that we can obtain age and growth information without relying on dead sharks captured in fisheries. That is a big deal.”

Though whale sharks appear to be quite long-lived, their lifespan is short compared to the Greenland shark's—in 2016, researchers reported they may live for 400 years.

Scientists Find a Possible Link Between Beef Jerky and Mania

Scientist have discovered a surprising new factor that may contribute to mania: meat sticks. As NBC News reports, processed meats containing nitrates, like jerky and some cold cuts, may provoke symptoms of mental illness.

For a new study, published in the journal Molecular Psychiatry, scientists surveyed roughly 1100 people with psychiatric disorders who were admitted into the Sheppard Pratt Health System in Baltimore between 2007 and 2017. They had initially set out to find whether there was any connection between certain infectious diseases and mania, a common symptom of bipolar disorder that can include racing thoughts, intense euphoria, and irritability.

While questioning participants about their diet, the researchers discovered that a significant number of them had eaten cured meats before their manic episodes. Patients who had recently consumed products like salami, jerky, and dried meat sticks were more likely to be hospitalized for mania than subjects in the control group.

The link can be narrowed down to nitrates, which are preservatives added to many types of cured meats. In a later part of the study, rats that were fed nitrate-free jerky acted less hyperactive than those who were given meat with nitrates.

Numerous studies have been published on the risks of consuming foods pumped full of nitrates: The ingredient can lead to the formation of carcinogens, and it can react in the gut in a way that promotes inflammation. It's possible that inflammation from nitrates can trigger mania in people who are already susceptible to it, but scientists aren't sure how this process might work. More research still needs to be done on the relationship between gut health and mental health before people with psychiatric disorders are told to avoid beef jerky altogether.
