Basketball Was Originally Played With Soccer Balls

By Chad Upton

The NBA has one Canadian team and 29 American teams. This is kind of fitting since basketball was invented by one Canadian teaching many students at what is now Springfield College in Springfield, Massachusetts. The game was invented out of the need for entertaining exercise to occupy his students during the long North Eastern winters.

The nets were originally Peach baskets and the ball was retrieved by ladder after each “basket”.  That obviously grew old quickly and a hole was made in the bottom of the basket so a pole could be used to knock the ball out of the basket. Of course, baskets have come a long way since then, and so has the ball. (more…)

Eating Before Swimming Won’t Cause Cramps

Mothers have been repeating the same advice to their kids for decades: “Don’t go swimming after lunch, you’ll get cramps and drown!” Some parents have taken it a step further, declaring that it’s not even safe to bathe after eating a meal. As it turns out, there is zero truth to this “danger” and not a single person has drowned from food-induced stomach cramps.

Origin

No one knows for sure how the myth started but the first version actually references baths, not swimming. In the early 1900s, a story popped up that warned parents about the dangers of bathing their children after a meal. The exact details varied with each version but the general idea was that a child should hold off on baths for at least one hour after eating. Over time, this myth got warped into the “no food before swimming” advice. (more…)

There is No “Versus” in Nature Versus Nurture

The “nature versus nurture” debate is alive and well today, even though science has debunked the entire argument. This might seem surprising since people still claim that certain traits are from genetics while others are from the person’s upbringing. On one side, people theorize that genetics affect everything from a person’s personality to their medical problems. On the other side, there’s the theory that everything is determined by how a person is raised: their environment, family, and childhood experience. As with most debates, the truth lies somewhere in the middle—nature and nurture constantly interplay.

History

The concept of nature versus nurture was first popularized by John Locke, an English philosopher and doctor. He believed in the “blank slate” theory, which stated that all human behavioral traits were based on their environment and how they had been raised. Later in history, Darwinism was becoming widely accepted and this led scientists to believe that behavioral traits were due to genetics, not the individual’s environment. This theory stated that a person’s personality was caused by genes and already set in stone at birth. Both scientists and philosophers continued the nature versus nurture debate until modern times. Now, scientists generally agree that the argument is a fallacy and reality is much more complicated than genes versus environment. (more…)

Bread Can Stop Ducks From Flying

duck family

Many people have fond childhood memories of feeding ducks at the park. Feeding some stale bread to the birds seems like it’d benefit them, too. Unfortunately, this is not the case. In reality, bread is one of the worst foods you could feed to ducks, especially if it’s cheap white bread.

Nutrition

The biggest issue with feeding bread to ducks is that it has very little nutritional value. This is especially true of white bread, which mainly consists of sugary carbohydrates and not much else. Bread is a high-calorie food that fills ducks up but lacks important vitamins and minerals. A poor diet can lead to a serious medical condition called angel wing. Ducks with this syndrome lose control over their wings, which begin to point outwards (hence the name). This eventually leaves the duck sick and incapable of flight. Unless treated right away, most ducks will succumb to the disease—there is no real cure. The risk of angel wing syndrome should be reason enough not to feed bread to ducks. (more…)

Caffeine is an Addictive Mind-Altering Drug

Caffeine is the most widely used stimulant in the world and over 80% of Americans consume some form of the chemical daily—whether it’s from tea, coffee, or soda. Caffeinated drinks have been around for most of written history and they’re probably not going away anytime soon. Most societies embrace at least one form of caffeine and after a while, it’s easy to forget that it’s actually a drug.

Caffeine is a psychoactive drug

Caffeine is a central nervous system stimulant—a psychoactive drug that causes increased alertness, faster locomotion, and other mental and physical changes. “Psychoactive” tends to be associated with drugs that cause visual hallucinations but it really just means that the chemical affects a person’s mental state. Both caffeine and cannabis are mild psychoactive stimulants; alcohol is a depressant or “downer.” (more…)

Dogs See Green and Blue not Black and White

When television shows and movies show events from a dog’s point of view, they usually switch to black-and-white. Dogs, like most mammals, actually do see colors—though not quite the same way humans do.

Human eyes contain photoreceptor cells called rods and cones. While both detect light, cones respond to specific wavelengths and are responsible for our color vision. Humans (and other primates) have three types of cones that can detect the red, yellow, and blue wavelengths. Dogs, on the other hand, only have two kinds of cone cells: yellow and blue. This means they have no trouble seeing shades of blue and yellow but have trouble differentiating them from red and related hues. To a dog, a red ball will simply appear to be a shade of green, similar to what a red-green colorblind human might see.

People who compete with dogs in outdoor sports often recommend certain colors for equipment based on what the dog will see. Although a human may have an easy time spotting yellow agility equipment on green grass, a dog will struggle to differentiate the colors. Instead, agility experts often choose shades of blue, which will usually stand out against greens and other colors in the yellow spectrum.

Dogs mostly rely on their sense of smell and hearing, which are both superior to our human senses. They still use vision, though, and can see colors—just not as many as we can. Understanding how our pets see the world can help us make things easier for them. Utilizing contrasting colors, for example, may help a dog find a toy during fetch or improve reaction times in canine sports. One day we might finally see an accurate depiction of dog vision in media, with shades of blue and green instead of greyscale.

The Five Second Rule Works Best on Carpet

The “five second rule” is an unofficial pass to eat food dropped on the floor—provided only a few seconds have elapsed. The general wisdom is that it takes several seconds for bacteria to transfer to the food item, making it safe to eat if picked up quickly. In one survey, 87% of people admitted to eating dropped food at least once. The five second rule was never backed up by science but some researchers have decided to test the idea.

In the first major study, researchers tracked the transfer of common bacteria, including E.coli, to food after it had been dropped. They found that carpet was less likely to transfer bacteria than smooth surfaces. While moist foods could become colonized within seconds, most foods were declared safe. For dry snacks, such as cookies, it could take 30 seconds or longer for bacteria to show up. The researchers decided that the five second rule works—in specific cases. (more…)
