Is It True What They Say About Guys With Big Feet?

We’ve all heard it before: The claim that the size of a man’s feet can tell you something about the size of his reproductive organ. Sometimes it’s as vague as "big in the shoes = big in the pants," and sometimes it's as precise as a complex algorithm that can supposedly deduce the subject’s masculine length, in inches, from his shoe size.

For a while, all that the people who claimed these sorts of things and their detractors had to go on was anecdotal evidence. All the “proof” either side had boiled down to, “yeah, well, I used to date a guy who [confirmed/disproved] what you say."

Thankfully, we have urologists, those brave men and women who boldly explore the nether regions of science most of us would never dare tread. In a handful of studies, they’ve searched for empirical evidence of the supposed foot-penis size connection and came up, ahem, a little short.

Let's Go to the Measuring Tape...

In 1993, two Canadian doctors measured the height, foot size and slightly stretched penile length of 63 men. The length of the penis was linked to both height and foot size, but the correlation was pretty weak. The researchers, who won the 1998 Ig Nobel Prize for Statistics for the study, warned that there was no “practical utility” in trying to predict penis size from either of those other measurements.

In 1999, Korean researchers measured the length and circumference of 655 Korean men’s flaccid penises, as well as the size of their feet, length of their toes and fingers, the sizes of their ears, mouth and even the amount of hair on their heads. They found a weak correlation between the length of the penis and the circumference of the penis (three cheers for being proportional!), but not with any of the other measurements. The circumference was also slightly correlated with height, weight, and the length of the third and first toes (in order of strength), but not enough that the scientists could conclude anything beyond “the size or characteristics of body extremities is not enough to predict the penile size.”

A year later, Richard Edwards found in the sixth edition of his online "Definitve Penis Size Survey" that there was no correlation between penis size and shoe size, but a strong one between penis size and height. There wasn't a vast difference in those sizes as men got taller, though. (Of course, we also have to keep in mind that all measurements were self-reported by the survey takers, which could color the results.)

In 2002, a study from the University College Hospitals in London measured penises and feet of 104 men and found no correlation whatsoever. While their results may be the most discouraging to guys who like to talk up their size 16 shoes at the bar, they did have one of the best introductions of all the studies I’ve read in my science writing days: “The penis appears in virtually every aspect of life.”

Here’s What You Need to Know About the New Coronavirus

This article has been updated.

This morning, the Centers for Disease Control and Prevention (CDC) confirmed the fifth case of the recently discovered coronavirus in the U.S. Find out what it is, where it is, how to avoid it, and all the other need-to-know information about the illness below.

What is the new coronavirus?

Coronaviruses are a group of viruses named for the crown-shaped spikes that cover their surfaces (corona is the Latin word for crown). According to the CDC, human coronaviruses can cause upper-respiratory tract illnesses, including the common cold, and can sometimes lead to more severe lower-respiratory tract issues like pneumonia or bronchitis.

Because this latest coronavirus, 2019-nCoV, is so new, health officials are currently trying to figure out how it works and how to treat it. It’s not the first time a potent new coronavirus has caused an international outbreak: SARS-CoV originated in Asia and spread to more than two dozen countries in 2003, and MERS-CoV first infected people in Saudi Arabia before spreading across the globe in 2012.

Where is the coronavirus outbreak happening?

Overall, China has more than 2700 confirmed cases, many of which are in Wuhan, a city in China’s Hubei province where 2019-nCoV was first detected last month. Around 50 additional cases have been reported in South Korea, Japan, Singapore, Hong Kong, Macao, Taiwan, Thailand, and Vietnam.

The CDC has confirmed five U.S. cases—in California, Arizona, Illinois, and Washington—all of whom had recently returned from trips to Wuhan. Right now, the CDC is screening all passengers from Wuhan, and their flights are only allowed to land at one of five U.S. airports: John F. Kennedy International Airport in New York, Los Angeles International Airport, San Francisco International Airport, Hartsfield-Jackson Atlanta International Airport, or Chicago O’Hare International Airport.

Chinese officials have shut down transportation to and from Wuhan, and they’re also temporarily closing tourist spots like Beijing’s Forbidden City, Shanghai Disneyland, and a portion of the Great Wall.

What are the symptoms of the new coronavirus?

Symptoms are similar to those caused by a cold or the flu, including fever, dry cough, and breathing difficulty. As of Monday morning, 81 people in China had died from the virus, and The New York Times reported that older people with preexisting conditions like cirrhosis, diabetes, and Parkinson’s disease are most likely to be affected.

How does the new coronavirus spread?

Because most of the early cases of 2019-nCoV were traced back to a seafood and meat market in Wuhan, health officials think the virus originally spread from infected animals to humans, but it’s now being transmitted from person to person.

Though scientists are still studying exactly how that happens, the leading theory is that it travels in tiny droplets of fluid from the respiratory tract when a person coughs or sneezes.

How do you avoid the new coronavirus?

The CDC is warning everyone to avoid any nonessential trips to Wuhan, and to avoid animals or sick people if you’re traveling elsewhere in China. If you’ve been to China in the last two weeks and experience any of the symptoms listed above, you should seek medical attention immediately—and you should call the doctor’s office or emergency room beforehand to let them know you’re coming.

Otherwise, simply stick to the precautions you’d normally take when trying to stay healthy: Wash your hands often with soap and water, cover your nose and mouth when coughing or sneezing, stay away from sick people, and thoroughly cook any meat or eggs before eating them.

Should you be worried about the new coronavirus?

The global health community is taking 2019-nCoV seriously in order to curb the outbreak as quickly as possible, but you definitely shouldn’t panic. The CDC maintains that it’s a low-risk situation in the U.S., and public health officials are echoing that message.

Caitlin Wolfe, a former consultant epidemiologist for the World Health Organization (WHO) and current doctoral student at the University of South Florida’s College of Public Health, tells Mental Floss that it’s too early to tell if the virus will become a nationwide outbreak, but the fact that cases have been detected in the U.S. “means patients and physicians are paying attention to the relevant symptoms and travel history,” and “the public health systems we have here are working.”

“The most important messages to get out to the American public are ones that share the information we know and avoid the alarmist/sensationalist narrative,” Wolfe says. “Early estimates from the Chinese authorities suggest that the R0, or the average number of people each person with the virus infects, is between 1.4 and 2.5. To put this in perspective, the average number of susceptible people infected by someone with the measles virus is between 12 and 18.”

While experts work to understand and fight the virus, keep an eye out for updates from the CDC and WHO and be extra committed to practicing good hygiene habits—which, as Wolfe points out, will also help protect you from the flu or even just a regular cold.

Has An Element Ever Been Removed From the Periodic Table?

Barry Gehm:

Yes, didymium, or Di. It was discovered by Carl Mosander in 1841, and he named it didymium from the Greek word didymos, meaning twin, because it was almost identical to lanthanum in its properties. In 1879, a French chemist showed that Mosander’s didymium contained samarium as well as an unknown element. In 1885, Carl von Weisbach showed that the unknown element was actually two elements, which he isolated and named praseodidymium and neodidymium (although the di syllable was soon dropped). Ironically, the twin turned out to be twins.

The term didymium filter is still used to refer to welding glasses colored with a mixture of neodymium and praseodymium oxides.

One might cite as other examples various claims to have created/discovered synthetic elements. Probably the best example of this would be masurium (element 43), which a team of German chemists claimed to have discovered in columbium (now known as niobium) ore in 1925. The claim was controversial and other workers could not replicate it, but some literature from the period does list it among the elements.

In 1936, Emilio Segrè and Carlo Perrier isolated element 43 from molybdenum foil that had been used in a cyclotron; they named it technetium. Even the longest-lived isotopes of technetium have a short half-life by geological standards (millions of years) and it has only ever been found naturally in minute traces as a product of spontaneous uranium fission. For this reason, the original claim of discovery (as masurium) is almost universally regarded as erroneous.

As far as I know, in none of these cases with synthetic elements has anyone actually produced a quantity of the element that one could see and weigh that later turned out not to be an element, in contrast to the case with didymium. (In the case of masurium, for instance, the only evidence of its existence was a faint x-ray signal at a specific wavelength.)
