If you were to guess Boston cream pie was invented in Boston or Nashville hot chicken originated in Nashville, you’d be correct. But sometimes, it’s not so obvious that a food is named after its place of origin. Examples of this include one of the most popular cheeses on the planet, a fruit found in every produce section, and a common source of plant-based protein. Here’s a look at six foods you may not have realized are named for the places they came from.

Cheddar Cheese

Long before it was produced in Vermont or Wisconsin, cheddar cheese originated in the English village of Cheddar, located in the county of Somerset about 145 miles west of London. The cheese’s origins date to the 12th century, when it was stored in caves in Cheddar that helped maintain an ideal humidity and temperature for maturation. The cheese became popular by 1170 — a year in which Baron Alured de Lincoln is recorded as buying 10,240 pounds of cheddar (though the records refer to it as just “cheese” from the Somerset region).

So when did people start calling it “cheddar cheese”? The Oxford English Dictionary cites the earliest written record of the term dating to 1659. Indeed, it was a common custom at the time for English cheesemakers to name products after their place of origin.

Lima Beans

English-speakers typically pronounce the “lima” in “lima beans” as LY-ma, which is differently from how they’d say “Lima, Peru” (LEE-ma). That may be why people in the U.S. don’t often realize lima beans are named after Peru’s capital city. 

What English-speakers know as lima beans refers to a native Andean legume called “pallar” in the region. The name “lima beans” caught on after the 16th-century Spanish conquest of the Incas. Peru’s European rulers exported the local legumes to the United Kingdom and later the United States, contained in packaging that stated they were made in Lima, Peru. As you may suppose, that earned the legume the name “lima beans” in those English-speaking nations.

Fig Newtons

It’s a common myth that Fig Newtons were named for the English polymath Isaac Newton. In reality, the name of the fig-filled treat is a nod to its place of origin. The cookie was first manufactured in 1891 by the Kennedy Biscuit Company in Cambridge, Massachusetts. 

At the time, the company liked to name its products for nearby communities (e.g., Shrewsbury biscuits, Beacon Hill cookies, etc.). So plant manager James Hazen opted to call this new cookie the “Newton” after the Boston suburb 6 miles away. In 1991, the city of Newton held a 100th anniversary celebration of the Fig Newton to honor that etymological connection.

Jalapeño Peppers

The name “jalapeño” translates to “of Jalapa” in Spanish. Jalapa — or Xalapa, as is the more formal spelling — is the capital city of the Mexican state of Veracruz, whose name comes from the Aztecan word “xalapan,” meaning “sand by the water.” 

Though jalapeño peppers aren’t commonly grown in Xalapa, the city is where they were widely commercialized thanks to a food pickling business there. Known as La Jalapeña, the business was known for its canned goods, chorizo, and chilies. In 1922, it received a patent for pickled chilies, and thus began the successful worldwide commercialization of these spicy peppers. They were exported far and wide, and the term “jalapeño pepper” — inspired in part by the packaging, which read “La Jalapeña” — was coined in the U.S.

Waldorf Salad

The Waldorf salad is named neither for a country nor a town, but rather for the Waldorf-Astoria Hotel in New York City. This isn’t to be confused with the still-standing Waldorf Astoria located on Park Avenue — instead, it refers to the historic hotel that was razed in 1929 so the Empire State Building could be built at the site. 

It was at that world-famous establishment that the leafless salad was created by Oscar Tschirky, a former busboy and popular maître d’hôtel who was a bit of a celebrity in his own right. In 1896, Tschirky published The Cook Book by “Oscar” of the Waldorf, which contained recipes he’d crafted in the hotel kitchen. The book included a recipe for the hotel’s namesake salad, though at the time the dish contained only apples, celery, and mayonnaise. Grapes and nuts were added later, sometime before the late 1920s.

Wiener Schnitzel

Wiener schnitzel has nothing to do with sausage, hot dogs, or any other foods that English speakers commonly refer to as “wieners.” Rather, the “wiener” in the name is German for the phrase “from Vienna,” as “Wien” is the German word for Austria’s capital city Vienna. “Schnitzel,” meanwhile, is the word for the breaded veal cutlet that serves as the dish’s primary component. Though variants of this dish have existed since the late 18th century, the term “wiener schnitzel” only dates to the 1850s, according to the Oxford English Dictionary.

That said, the name “wiener” as a nickname for hot dogs also has Viennese origins. In that case, the word refers to a Viennese-style sausage called “wienerwurst.” The culinary nickname “wiener” was coined in the United States no later than 1880, and it originally referred specifically to sausages from Vienna. But by the 1930s, Americans had begun saying “wiener” to describe hot dogs and other sausages, regardless of whether they came from Vienna.

In the U.S. and many other parts of the world, students are graded on an “A” to “F” scale, seldom questioning why one letter is missing. “E” isn’t found on most modern report cards — but why? 

This isn’t a simple oversight, but rather the result of centuries of evolving grading practices. By tracing the history of student evaluations, we can uncover why the letter “E” quietly disappeared from report cards across the United States.

Early Modern Grading Didn’t Use Letters

In 1785, Yale University President Ezra Stiles introduced what is believed to be the first proper grading system in the American colonies. That four-point scale, written in Latin, comprised the following categories: optimi (best), secondi optimi (second best), inferiores boni (less good), and pejores (worse). 

By 1837, mathematics and philosophy professors at Harvard had adopted a 100-point grading system, though it looked different than the one we use today. The modern 100-point scale features corresponding letter values and typically looks like this: “A” is 90-100, “B” is 80-89, “C” is 70-79, and “D” is 60-69.

But Harvard used a strictly numerical scale without any corresponding letters, and the ranges were as follows: 100 (perfect), 75-99, 51-74, 26-50, and 25 or below. The average grades followed a bell curve, with most students hovering around 50. Scores on both extremes (above 75 and below 25) were rare. 

Numerical grades gained traction across the country, and by the early 20th century, it became the most common grading system.Teachers at schools of all levels began assigning and recording grades using this 100-point scale, and, for the first time, modern grades inched toward a universal system.

The Rise and Fall of “E”

Although numerical grading was the most popular method of assessing students from the mid-1800s through the early 1900s, another system emerged and evolved alongside it: letter grades. Teachers at Mount Holyoke College in Massachusetts began using letter grades as early as 1884. By the 1896-1897 school year, Mount Holyoke had become the first U.S. school to have documented use of a uniform letter grading system.

Letters were assigned to numerical ranges, but those ranges differed from Harvard’s. Instead, the system looked similar to what’s used in schools today: An “A” grade (excellent) was 95-100, “B” (good) was 85-94, “C” (fair) was 76-84, “D” (barely passed) was 75, and “E” was a failing grade, though it didn’t have a corresponding number. 

The following year, Mount Holyoke altered its grading system, adding an “F” for the first time. The numerical ranges were adjusted to include the new letter, and the grading scale spanned “A” through “F.” Interestingly, though, the college also retained the “E,” thus increasing its grading scale from five categories to six. But this move proved unpopular, and other schools began removing the “E” grade.

Experts have several theories about why “E” began to fade, including a push for a more efficient system. By the early 20th century, educators believed that fewer grading categories would help teachers streamline the process, simplifying the system. 

Isidor Edward Finkelstein, author of The Marking System in Theory and Practice (1913), was influential in this line of thought. Specifically, he and his colleagues believed that five divisions was the optimal number on a marking scale. That meant the modern grading system needed to drop one letter. As researchers Kimberly Tanner and Dr. Jeffrey Schinske wrote in their article “Teaching More by Grading Less (or Differently),” the “E” grade was an easy target because “F” so clearly stood for “fail.”

The article cites another issue with “E”: Some students assumed it stood for “excellent” despite it marking unsatisfactory grades, making it the most misunderstood letter out of the bunch. It was a perfect storm — “F” was a clearer stand-in for “fail” while “E” confused and crowded the grading scale. By the 1930s, “E” grades had disappeared from American schools.

“E” Remains in Some Grading Scales

During the latter half of the 20th century, the letter grading system “A” to “F” (excluding “E”) became standard across the country. But that doesn’t mean there aren’t exceptions. In elementary schools, a different letter scale is often seen on report cards, especially for younger students in kindergarten through third grade. 

For instance, grades may include “D” (“developing”), “E” (“expanding”), “S” (“satisfactory”), and “N” (“needs improvement”). As these grading systems vary by school district, the “E” may also mean “excellent” or “exceeding expectations.” So no, “E” hasn’t been entirely banished from the modern education system, but it has undoubtedly lost its place in the standard lineup of U.S. letter grading, remaining a curious omission from student report cards across America.

Blue jeans have long been a staple of wardrobes around the world, worn by everyone from construction workers to rock stars. Certain looks, from James Dean’s cuffed 1950s denim to Steve Jobs’ faithful 501s have even become ingrained in our cultural imagination. The classic color of jeans now feels essential to their identity, but it wasn’t originally chosen for stylistic reasons. So why are jeans typically blue?

Feeling Blue

Long before Levi Strauss patented riveted work pants and created the modern blue jean in 1873, laborers across medieval Europe also wore trousers that were dyed blue, first with locally grown woad (a plant in the mustard family) and later with imported indigo. Those early work pants weren’t jeans as we know them today, but they did set the stage for our modern version — particularly the color. 

Blue dye wasn’t used simply because it was available — it proved handy for other reasons, too. The dark color hid the grime that came with sweating in the sun or toiling away in soil, and indigo’s unique properties made it a particularly durable choice. As fabric comes out of the dye vat, exposure to the air causes indigo to oxidize and solidify, forming a thin coating around the fibers. This helps indigo resist fading far better and for far longer than most other natural dyes.

There may have been another, subtler benefit to dying trousers blue: The Indigo plant has long been valued in traditional Chinese and Indian medicine for its antibacterial properties, and it’s possible that indigo-dyed garments resisted odor slightly better than undyed cloth, an obvious advantage at a time when washing clothes was infrequent.

Modern Blue Jeans Are Born

By the mid-19th century, cotton pants had become standard workwear for miners, railroad workers, and other laborers in the American West, and the textile industry that supplied them was booming. American mills such as the Amoskeag Manufacturing Company in Manchester, New Hampshire — then one of the largest textile producers in the world — were reliably producing indigo-dyed cotton twill known as denim, a proven workhorse material that had achieved popularity throughout Europe and the Americas.

One of Amoskeag’s customers, a San Francisco dry-goods merchant named Levi Strauss, stocked the company’s blue denim fabric, and Reno tailor Jacob Davis purchased it. When Davis began reinforcing work trousers with metal rivets, he did so on pants made of both undyed duck canvas and blue denim. His customers gravitated toward the most practical color: dark blue. 

Eventually, synthetic indigo, which was developed in the 1890s, made blue denim cheaper and easier to produce than ever before. By the 1900s, undyed work wear was all but discontinued, and blue became the de facto dye for work pants.

A Style Icon Emerges

Not only was blue denim standard workwear by the 20th century, but it also became a cultural juggernaut. Hollywood’s cowboys of the 1930s cemented blue jeans as symbols of rugged Americana; soldiers wore denim abroad during World War II, spreading the look’s popularity overseas; and teenagers in the postwar years embraced the garment as a uniform of rebellion. Women who had worn denim in wartime factories also continued reaching for it long after the war ended.

By that point, blue jeans’ ability to retain their sturdiness even as the dye subtly faded at creases and edges had become a signature style. Today, jeans are a timeless wardrobe staple — around 3 billion pairs were sold in 2022 alone — and though they’re available in many colors, the classic pair of jeans will always be blue.

You probably reach for some kind of kitchen utensil every day, whether a fork, spoon, spatula, or cheese grater. These tools seem pretty straightforward, but some conceal clever uses that may go unnoticed. For instance, have you ever used the little loop on your vegetable peeler? Or measured pasta with your serving spoon?

Some of these features were designed intentionally, while others have been happily found to be useful in more ways than one. Here are a few of the ingenious hidden features found on everyday kitchen tools.

Notches on Kitchen Shears

Kitchen shears are an often-overlooked utensil. A good pair can do more than just tear open food packaging in a pinch; they’re an easy way to cut through meat, chop vegetables, finely snip herbs, and even slice up a rustic pizza. 

But that’s not all they do. Take a look at the blades on your shears — if one edge has a crescent-shaped cut-out, that’s a bone notch, meant to help stop slippage and cut through bones in poultry or fish. 

There’s another neat feature, too: On the inside of the handles, shears often have serrated metal teeth that form a circle, which can be used to twist open a stubborn jar or twist-top bottle or even to crack shelled nuts or shellfish.

Spaghetti Spoon Measuring Holes

That hole in the center of your pronged pasta server isn’t just for drainage when scooping pasta out of boiling water. Depending on the spoon’s design, the opening may also work as a measuring tool for approximating a single serving of dry spaghetti noodles.

Keep in mind, however, that while the latter can be handy, it’s not universal. Pasta servers aren’t made to one specific standard, so the size and shape of the center hole can vary widely. Serving sizes vary too; a standard package of store-bought spaghetti considers a portion to be roughly 2 ounces (with roughly a quarter-sized diameter when held in a bunch), but no one spoon will reliably measure that exact amount every time.

Vegetable Peeler Scoops

Many vegetable peelers are adorned with a small, barely noticeable bump on them. This can usually be found right on the top of older-style straight peelers, while on newer, wider Y-shaped peelers, it’s usually on the side. 

This notch is designed to remove potato eyes or other vegetable and fruit blemishes without having to switch to a paring knife. It’s a small but useful detail that can save time and frustration — and maybe a nicked fingertip or two.

It’s simple to use: Place the notch over the unwanted spot and scrape or scoop it away. This works on potatoes, carrots, or any firm fruit or vegetable with imperfections, and you barely even have to break your peeling stride.

Box Graters’ Zesting Side

Many people associate box graters so strongly with cheese that they simply refer to it as a cheese grater. And, yes, a box grater is primarily used for grating cheese. One side grates the long, thick shreds ideal for melting (the most commonly used side), while another shreds cheese or vegetables into finer strands, and another into thin slices. But what about those imperceptibly tiny holes that feel almost dangerous to the touch? 

That’s known as the rasp-style grater, and while it can indeed be used for cheese — hard varieties such as parmesan work best — it’s best when zesting citrus. You’ll want to press the rind or other food lightly against this side and move it in short strokes, taking care not to scrape your knuckles. It’s also excellent for grating tough spices such as cinnamon and nutmeg.

Holes in Cutting Board Handles

Many cutting boards have wide handles that make it easier to hang them up or pull them out from inside a cupboard,  but they also work as a funnel for transferring chopped food or food scraps. Enterprising home cooks have figured out that if you slide the handle opening over the edge of the counter, you can easily push scraps through the hole and into a garbage or compost bin below — no more fluttering onion skins escaping as you carry your board from point A to point B.

Additionally, you can lift the cutting board over to your cooktop and safely slide prepped ingredients into a pot or pan. The board can also act as a splashguard in the process if the water or cooking oil is already hot. 

Of course, not every cutting board has a handle with a hole, nor will the holes always be the ideal shape and size for moving food or waste through. If yours does, however, you may just have a new way to use one of your trustiest tools.

Colander Holes for Herbs

Colanders aren’t just for draining pasta — their perforations can also be used to quickly and neatly strip herb leaves from their stems. Simply feed the stems through the holes from the inside to the outside, pull, and the leaves slide off with minimal effort right into the colander. 

You’ll want to use the medium-sized holes on your colander and make sure you’re not using stems or leaves that have gone too limp or woody. It makes for a little bit of extra cleanup, but it may be worth it to avoid taking up drawer space with a one-use tool such as a specialized herb stripper.

Spoon Holders in Saucepan Handles

We’ve all been there: standing over a tomato sauce simmering away on the stove with a trusty wooden spoon in hand. But when you’re done stirring, where do you rest the spoon without leaving a mess on the counter or grabbing an extra dish if you don’t have a specialized spoon rest? 

As it turns out, many saucepan handles solve this problem with the small hole at the end of the handle. While that hole is primarily meant for hanging the pot on a hook or peg, it can also double as a spoon rest with teh right setup. 

Simply stick the bottom end of the spoon’s handle the slot, leaving it slanted up toward the pot so any drips will fall back in the sauce and not all over your counter. Just be cautious and give the spoon a quick check for any heat transfer before grabbing it to finish your dish.

Weather forecasts often list two temperatures side by side: the actual air temperature and the “feels like” temperature. While the first is straightforward, the second is more complex — and often more important. 

The “feels like” value reflects how your body perceives temperature in real-world conditions rather than how a thermometer measures it in a controlled environment. It accounts for the fact that humans warm up, cool down, sweat, shiver, and respond to the environment in ways that can make a mild day feel sweltering or a breeze feel freezing. These factors can dramatically impact your comfort level and, in some cases, your safety.

This adjusted temperature is the result of careful calculations that combine physics, meteorology, human biology, and environmental science. Multiple elements interact to determine how heat transfers between your body and the surrounding air, and each of those elements can push the perceived temperature higher or lower. 

Whether you’re wondering why humid days feel oppressive or why a winter wind seems to cut right through your layers, the “feels like” temperature offers a scientific explanation for the sensations you experience every day.

Wind Chill and Heat Index

The “feels like” temperature is based almost entirely on two standardized measures, the wind chill and the heat index. Those formulas estimate how efficiently your body exchanges heat with the surrounding air under cold or hot conditions. 

Wind chill represents how cold your skin feels on a windy day, while the heat index reflects how hot it feels during summer humidity. Both indices assume standard, shared conditions, typical clothing, and dry skin (as opposed to wet conditions such as rain).

While those formulas can’t capture every variable, they provide a far more accurate picture of real-world conditions than air temperature alone. With this metric, meteorologists can interpret raw data and apply it to the human experience, giving people clearer guidance on how to dress, how long to stay outside, and when to take precautions against extreme weather.

How Does Wind Chill Work?

On winter days, the wind can make temperatures feel lower than what the thermometer reads. This effect is captured by the wind chill index, which calculates how much faster heat leaves your skin when the wind is blowing. 

Normally, your body warms a thin insulating layer of air around your skin, helping retain heat. Wind sweeps that warm layer away, forcing your body to lose heat at a faster rate. The stronger the wind, the more intense the heat loss, and the colder you feel.

Meteorologists use formulas that account for wind speed and air temperature to produce the wind chill number, which reflects how quickly skin will cool under those conditions. While wind chill doesn’t lower the actual air temperature, it can increase the risk of frostbite and hypothermia, making it an important measure in winter weather advisories.

How Does the Heat Index Work?

If you’ve ever visited Florida or another notoriously humid area, you’ve probably heard someone say, “It’s not the heat, it’s the humidity.” That’s because humidity makes the air feel warmer than the measured temperature. The body cools itself by sweating, but sweat only reduces heat if it can evaporate. High humidity slows evaporation, meaning the body struggles to release heat efficiently.

The heat index combines air temperature and relative humidity to estimate how hot it feels when evaporation (and therefore cooling) is impaired. So a humid 90-degree day may feel like 100 degrees or higher because your body can’t shed heat efficiently. This is why deserts can feel scorching yet tolerable, while humidity in places like the Southern U.S. can feel oppressive even at lower temperatures.

What Other Variables Affect How Cold or Hot You Feel?

Although wind chill and heat index are the only standardized components of a “feels like” forecast, real-world comfort is shaped by a much wider set of factors. Sunlight, for example, can significantly raise perceived warmth because radiant heat warms skin, clothing, and surrounding surfaces — something the heat index doesn’t account for. Moisture plays a major role, too: Wet skin, soaked clothing, or heavy sweat accelerates heat loss in cold conditions and interferes with efficient cooling in hot conditions.

Even the landscape can influence comfort — paved surfaces, shaded parks, waterfronts, and wind tunnels between buildings all create microclimates that feel warmer or cooler than the official forecast may indicate. In urban areas, this effect is especially pronounced due to the “urban heat island” phenomenon, in which asphalt, concrete, and dense building clusters absorb and re-emit heat, raising temperatures relative to surrounding rural areas. 

Even small changes in street orientation, building height, or surface materials can create noticeable temperature differences, meaning two locations even just a few blocks apart can feel significantly different to the human body.

Another Measure for Assessing Human Comfort

While meteorologists don’t build those additional variables into the standard “feels like” number, other experts often do. Occupational safety specialists, sports science experts, the military, and public health researchers use more comprehensive tools — such as the Wet Bulb Globe Temperature (WBGT) — to assess heat-related stress on the human body. This metric takes sunlight, humidity, wind speed, cloud cover, and other environmental conditions into account for the most precise assessment.

Ultimately, however, comfort is personal and can vary greatly between individuals. Your clothing, activity level, location, sun exposure, and even your own physiology can shift how conditions truly feel to you. The “feels like” forecast provides a helpful baseline — the rest is up to your body and the environment around you.

From Oscar winners to Hall of Fame musicians and world-class athletes, there are some celebrities whose accomplishments in the classroom are equally impressive as the talents that brought them fame. 

Many of these well-educated A-listers have put their advanced degrees to use, juggling careers in the world of entertainment and academia. Here are six multitalented stars who can boast Ph.D.s among their other accomplishments.

Brian May: Ph.D. in Astrophysics

Before playing guitar in the legendary rock band Queen, Brian May had his sights set on a career in astrophysics. May was an accomplished student from a young age, studying advanced physics, mathematics, and applied mathematics at Hampton Grammar School in London. He also received a bachelor’s degree in physics from Imperial College London in 1968 — the same year he and Freddy Mercury cofounded the band Smile, the predecessor to Queen.

From 1970 to 1974, May pursued a Ph.D. in astrophysics at Imperial College London. But his budding rock ’n’ roll career was taking off at the same time. The band released their first two albums in 1973 and 1974 to such success that May decided to put his academic career on hold.

The rock star suspended his studies for more than three decades, before re-registering for a Ph.D. in 2006. The following year, he submitted a thesis titled, “A survey of radial velocities in the zodiacal dust cloud,” after which he was awarded his advanced degree at long last. 

May attended graduation in 2008 and now works with both NASA and the European Space Agency (ESA) to design stereoscopes of images taken during celestial missions. May has also used his own publishing house, the London Stereoscopic Company, to publish 3D books about astronomy.

Shaquille O’Neal: Doctor of Education

In addition to being a Hall of Fame basketball player, movie star, professional wrestler, and former police officer, Shaq is also a Doctor of Education. The Lakers legend earned his EdD from Miami’s Barry University; in a statement released by the school, O’Neal said his pursuit of the degree was to honor his mother, “who always stressed the importance of education.”

The Big Aristotle, as he’s affectionately known, spent four and a half years juggling his studies while playing in the NBA. He achieved an admirable 3.81 GPA, virtually attending classes between games. 

Shaq retired from the NBA in 2011 and graduated with his doctorate degree the following year. This was Dr. Shaq’s third college-level degree, having also earned a Bachelor of Arts in General Studies from Louisiana State University in 2000 and an MBA from the University of Phoenix in 2005.

Mayim Bialik: Ph.D. in Neuroscience

Actress Mayim Bialik shot to stardom portraying the title character on the sitcom Blossom in the early 1990s before portraying neuroscientist Amy Farrah Fowler on The Big Bang Theory in the 2010s. The latter character wasn’t far removed from Bialik’s real-life persona, as she herself has earned a Ph.D. in neuroscience.

Bialik shifted her focus away from acting and toward academics in the early 2000s. She earned a bachelor’s in neuroscience from the University of California, Los Angeles in 2000 and soon returned to UCLA to pursue a doctorate in that same field. 

The actress achieved her Ph.D. in 2007, with a focus on the effects of oxytocin and vasopressin on obsessive-compulsive disorder in adolescents with Prader-Willi syndrome. In addition to her resurrected entertainment career, Bialik is now a vocal advocate encouraging young girls to pursue careers in STEM. Bialik also put her profound intelligence to work while co-hosting TV’s Jeopardy! from 2021 to 2023.

Peter Weller: Ph.D. in Italian Renaissance Art History

You may know him best as RoboCop, or perhaps as the Academy Award-nominated director of the 1993 short film Partners, but Peter Weller is also an expert in Italian art. 

Weller’s interest in art began to percolate in the 1970s as he hobnobbed with artists while living in New York City. But it wasn’t until seeing Pablo Picasso’s “Guernica” at the Museum of Modern Art that Weller had a revelation. He later told Artnet that he finally “started to see the connective tissue of visual art.” 

Weller was later drawn to artists such as the Italian Renaissance painter and architect Giotto, and began his focus on that era. With decades of acting behind him — he starred in RoboCop in 1987 — Weller enrolled at Syracuse University in 2004 and completed a master’s degree focused on Roman and Renaissance art before pursuing a Ph.D. in the field. 

Weller wrote and defended a dissertation in 2013 about humanist artist Leon Battista Alberti and earned his doctorate the following year. He continues to be involved in art education — in 2023 he established UCLA’s Weller Family Graduate Art History Fund, which helps fund travel and research for graduate art students.

George Miller: Doctor of Medicine

Director George Miller is one of the few people who can say they’ve achieved both an Oscar and a doctorate in medicine. A film career wasn’t always the primary aim for this visionary behind the Mad Max franchise; he originally studied medicine at the University of New South Wales. 

Miller graduated from medical school in 1971 and went on to complete a residency at St. Vincent’s Hospital in Sydney, Australia.
While working as an emergency room doctor in the 1970s, Miller was deeply affected by the carnage caused by car accidents, inspiring  him to imagine the dystopian universe of Mad Max. Miller released the first Mad Max movie in 1979, which proved to be a huge success and saw him transition out of the medical industry to pursue filmmaking full time.

Among all your senses, touch is the only one that spans your entire body. The skin — your largest organ — not only protects you from injury and infection but also constantly gathers information about pressure, temperature, vibration, texture, pleasure, pain, and potential threats. 

Unlike vision or hearing, which operate at a distance, touch is immediate and immersive, feeding the brain continuous updates about your body and surroundings. Scientists are increasingly discovering that touch is more than a simple bodily function; it’s a foundation of social connection, emotional regulation, and even memory.

What makes touch especially interesting is how complex and psychologically layered it is. Each sensation engages a network of specialized receptors and neural pathways the brain must interpret — rapidly and often unconsciously. The way those signals are processed reveals just how nuanced this seemingly simple sense really is.

Credit: SanyaSM/ iStock

Touch Is the First Sense To Develop

Touch develops remarkably early in human life. By around eight weeks of gestation, a developing fetus can respond to light pressure around the lips, and sensitivity quickly spreads across the body as the nervous system forms. Specialized receptors for pressure, temperature, and movement become active months before birth, creating the foundation for how you later interpret the physical world.

This early sense helps shape the developing brain and is crucial for survival and healthy growth. Touch guides fetal movements, supports neural organization, and after birth, it becomes essential for bonding, emotional stability, and healthy social development long before vision and hearing fully mature.

Gentle Touch Helps Regulate Emotions

One of the most interesting discoveries in touch research is the role of C-tactile afferents, aka nerve fibers tuned specifically to gentle, caressing strokes. Those fibers send signals directly to areas of the brain involved in emotional processing, including the insular cortex. 

When activated, they can reduce stress hormones, lower heart rate, and trigger the release of oxytocin, a hormone associated with bonding and trust. Those physiological responses help explain why a gentle touch from a trusted person can immediately soothe you, soften distress, and create a sense of safety.

The emotional effects of gentle touch are especially profound in early development. Studies on newborns and premature infants show that skin-to-skin contact — sometimes called “kangaroo care” — can regulate breathing, stabilize body temperature, and promote healthier weight gain, all while strengthening parent-infant bonding. 

In adults, similar forms of nurturing touch continue to buffer stress and enhance social connection. Experiments have found that people who receive supportive touch from a partner experience reduced neural responses to threat and even perceive painful stimuli as less intense.

Touch Can Influence Our Decisions

Touch can subtly shape the decisions we make, often without our awareness. Research on embodied cognition shows that physical sensations such as softness, firmness, warmth, or weight can influence how we interpret situations and behave in response. 

For example, holding a warm object can momentarily increase feelings of trust and generosity, while rough textures can make social interactions seem more difficult. Even something as small as an item’s weight can affect judgment: People holding heavier objects have been found to rate issues as more serious or consequential than people holding something light. That effect reveals how the brain uses tactile cues as shortcuts, blending physical sensation with abstract evaluation.

In one 2010 study, participants engaged in a simulated negotiation with a car dealer while seated in a chair that was either soft or hard. Those in soft chairs tended to make higher second-round offers than those in hard chairs, suggesting physical comfort can increase psychological flexibility.

There’s a Reason Your Skin Gets Pruney in Water

When your fingers or toes wrinkle in water, it’s not just soggy skin; it’s a nervous system-driven adaptation to help your sense of touch work better in a slippery environment. While the outermost layer of skin does absorb some water, the distinctive prune-like wrinkling pattern is triggered by your sympathetic nervous system. Blood vessels beneath the skin constrict, changing the tension in the tissue and creating those familiar ridges.

The water-formed wrinkles enhance how you interact with wet surfaces. By channeling water away from the fingertips — much like tire treads — they improve tactile control and surface contact. Pruney fingers are the way your body preserves fine touch and dexterity when the normal friction enabled by dry skin disappears.

Touch Helps Your Brain Know What’s Part of Your Body

Touch is central to how your brain determines what is part of your body. When visual and tactile signals align — such as seeing a hand that’s not yours touched while feeling the same touch — the brain can interpret the touched surface as “you.” Experiments with delayed or mismatched touch show how quickly that system can falter, revealing how actively — and continuously — the brain maintains a sense of bodily ownership.

The classic rubber hand illusion is an example of this. When a visible fake hand is stroked near and at the same time as a hidden real hand, the brain merges the visual and tactile signals. Within minutes, many people begin to feel the rubber hand as their own, demonstrating how touch, vision, and proprioception (the body’s internal sense of movement and position) are woven together to create the feeling of self.

This fluid sense of self becomes especially clear in phantom limb experiences. After an amputation, many people continue to feel sensations — warmth, pressure, pain — in the missing limb. Those sensations arise from the brain’s map of the limb, which remains intact even after the limb is gone.

Techniques such as mirror therapy show how this map can be reshaped. In mirror therapy, a mirror is positioned so the reflection of an intact limb appears where the missing limb would be, creating the visual illusion that the lost limb is still present and moving. 

That visual feedback can help the brain reorganize its internal body model, reducing phantom sensations or pain. The success of such interventions shows that even deeply rooted bodily sensations can shift when the brain receives new sensory information.

Touch Can Create Sensations That Aren’t Really There

Touch doesn’t always reflect the physical world exactly as it is.  When sensory signals clash or are incomplete, the brain fills in the missing information — sometimes incorrectly. In many cases, the nervous system must infer what a sensation means, especially when signals are conflicting or ambiguous, and this guesswork becomes particularly noticeable when it comes to temperature.

The thermal grill illusion, in which alternating warm and cool bars placed against the skin produce a burning or painful sensation. Neither temperature is painful on its own, yet the combination activates overlapping neural pathways that the brain misreads as extreme heat. 

A similar phenomenon happens when you put your very cold hands under warm water — the warmth can briefly feel uncomfortable or even painful. In both cases, the sensation is created by the nervous system’s attempt to reconcile conflicting temperature signals.

Expectation Shapes What You Think You Feel

Touch also relies on prediction. Before you even make contact with an object, your brain estimates how heavy, smooth, sharp, or firm it should be, and those assumptions shape what you expect to feel. 

This is obvious in the size-weight illusion, in which smaller objects feel heavier than larger objects of the same mass — because the brain expects the larger objects to be heavier. When the object is lifted, the mismatch between expectation and sensation creates a strange, persistent perceptual error.

Those constant cycles of prediction, comparison, and correction happen constantly, usually without our awareness. But illusions of temperature and weight prove touch isn’t a simple reflection of physical reality, but a continuous interpretation. The brain draws on assumptions, shortcuts, and memory to construct what you think you feel, and those can occasionally take you by surprise.

Most modern cars are expertly crafted to protect their occupants from the perils of the road. Yet there was a time in the not-so-distant past when many vehicles were much more unsafe to drive, due to dubious design elements such as lap-only seatbelts and fuel tanks in vulnerable locations. Here are five old-school car features that would never be street-legal today.

Non-Collapsible Steering Columns

Before the late 1960s, cars came with a non-collapsible steering column — a rigid, one-piece metal shaft that linked the steering wheel directly to the car’s wheels. While these worked just fine for run-of-the-mill daily driving, in the event of a high-speed, head-on collision, the steering columns essentially transformed into steel javelins that could impale the driver. 

Given their lack of flexibility, the shafts would transfer all the force from the oncoming collision directly into the driver’s head or chest. Nowadays, cars are often equipped with a collapsible steering column made of multiple parts meant to absorb the force of impact. The safety feature entered widespread production in 1967 thanks to General Motors, and Chrysler and Ford followed suit by the end of the following year.

Lap-Only Seatbelts

While the earliest cars didn’t feature any seatbelts at all, lap-only belts weren’t much of an improvement. The design made its debut in communal streetcars in the 1930s and safety belts were later introduced in personal vehicles by Nash Motors in 1949. 

Lap belts could save people from being jettisoned out of the car and into the street, but they only restrained the body’s lower half. In the event of an accident, a passenger’s upper torso and head could still lunge forward with great force, potentially causing serious injuries.

In 1955, inventors Roger Griswold and Hugh De Haven filed a patent for a seatbelt that included both a lap and shoulder strap — an early incarnation of what we use today. Nonetheless, lap-only belts remained the standard throughout the 1950s and ’60s. And many passengers often ignored those entirely, as it wasn’t until 1984 that New York became the first state to mandate the use of seatbelts. 

Thankfully, the much safer three-point seatbelts began appearing in 1959, thanks to Nils Bohlin of Volvo, who designed them for a new line of Swedish cars. Other manufacturers took note of the improved safety, and seatbelts that went over the lap and shoulder, thus keeping the whole body secure upon impact, became increasingly common throughout the 1970s and ’80s.

Pop-Out Windshields

The 1948 Tucker sedan was the first vehicle to feature a pop-out windshield — an innovative design element intended to improve safety. The idea was for the windshield to automatically eject after a crash, thus giving passengers an opening to escape if need be, and also avoiding cuts from shattered glass. Or so the thinking went. 

There were, however, two major problems with the pop-out window. First, many people didn’t use seatbelts at the time, so they were propelled forward in a high-speed collision. Without any windshield, this meant passengers would be thrown from the car onto the street. 

In addition, there was nothing to offer protection from any oncoming debris once the windshield popped out. For example, if a car were to be flipped onto its side, the windshield would fly off and there would be nothing shielding passengers from detritus flying in through the open gap. 

This is a far cry from windshields now, which are laminated and designed to stay in place when shattered. Modern windshields also contain a layer of polyvinyl butyral that’s meant to prevent any shattered glass from entering the vehicle even if the exterior glass layer cracks.

Rear-Mounted Fuel Tanks

Starting in the early 20th century, it was common for car manufacturers to place the fuel tank behind the rear axle and adjacent to the bumper. This design trend continued well into the late part of the century, despite posing a clear safety hazard. 

A rear-mounted fuel tank was highly vulnerable to any high-speed crashes from behind, as this would force the fuel tank forward into the vehicle’s rear axle, thus potentially causing the tank to rupture and explode. Even minor fender benders posed a serious risk, as a slight bump from behind could cause the tank to malform, rupture, and leak fuel.

This flawed design was highlighted in the 1970s thanks to the Ford Pinto, a model that was taken out of production after just 10 years. There were many instances of cars colliding with Pintos from behind, resulting in a ball of flame. Furthermore, the Pinto car doors were known to jam after accidents, thus preventing occupants from escaping the inferno. 

Those incidents helped highlight the fact the need for fuel tanks to be placed in a safer location, which is why manufacturers now put fuel tanks ahead of the rear axle and between the wheels. This provides a buffer from all crashes, whether they impact the car from behind, the front, or the side.

Sharp Decorative Adornments

While some vintage car features posed a danger to the vehicle’s occupants, other features put pedestrians and bikers in harm’s way. One notable example is hood ornaments, which were often hard as steel and featured sharp angles, posing an increased risk to pedestrians who were hit by cars.

Moreover, the hood ornament’s sharp point would stick out above the front bumper and could shatter the windows of oncoming cars in a collision. These concerns motivated carmarkers such as Bentley to design hood ornaments that retracted inside the hood during impact, while other car companies decided to phase them out altogether.

Sleek tailfins — such as the ones on a 1959 Cadillac Eldorado — were another decorative feature that doubled as a safety hazard. With their sharp, rigid edges, the tailfins could scrape, slice, or puncture anything they came into contact with. Today, tailfins are very much a relic of the past, as modern cars feature more rounded exteriors designed to put safety first.

Astronauts are members of a very elite club: As of 2025, only around 670 people have been to space, and fewer still have spent a significant amount of time beyond Earth’s atmosphere. Those who have had an extended stay in space tend to be crew members of the International Space Station (ISS), which has housed more than 280 individuals representing 26 countries since it became fully operational in 2009. 

The life of an astronaut is full of adventure, drama, and a certain amount of glamour — but life in space still requires many of the same basic chores we have to handle here on Earth. Of course, without gravity’s assistance, even the most mundane tasks can become complex feats of engineering. Here’s how astronauts aboard the ISS adapt to some familiar chores while traveling at a speed of 5 miles per second some 250 miles above Earth.

Bathing

Water has always been problematic on the ISS, for a number of reasons. It’s heavy, so it comes at a premium in terms of shuttle resupplies; it doesn’t behave in microgravity; and it’s potentially dangerous considering all the electronics aboard the station. Bathing, therefore, is a tricky business. 

In the 1970s, when NASA operated its first space station, known as Skylab, astronauts used a collapsible tube shower system. But this system took about two hours per shower, mainly because every water droplet had to be painstakingly collected after bathing. On the ISS, there is no shower — astronauts have instead returned to the old-school way of washing, as used during the Gemini and Apollo missions: a simple sponge bath

They squirt small amounts of water and liquid soap onto their skin and use a special rinseless shampoo to wash their hair, then use towels to wipe off any remaining water. An airflow system nearby quickly evaporates excess water, preventing it from floating around the station.

Housekeeping

Astronauts on the ISS maintain a strict cleaning schedule. The station isn’t a sterile environment, as each astronaut brings microbes from Earth that can potentially flourish on the space station. Cleanliness is therefore a serious priority in the confined environment, both to protect the people living there and the technology and ongoing experiments aboard the orbiting lab. 

Each astronaut is assigned a regular schedule to wipe down surfaces with antimicrobial wipes, including kitchen areas and sweaty exercise gear. Vacuuming — using a surprisingly standard vacuum just like we’d use on Earth — is also important, especially for cleaning the filters and vents where dust accumulates. It’s a noisy process, but at least astronauts don’t have to worry about annoying the neighbors. In space, no one can hear you clean.

Taking Out the Trash

Astronauts generate about 4.4 pounds of trash per person per day, including packaging, paper, tape, filters, food containers, and personal hygiene items. Chucking trash directly into space may seem like the simplest option, but this naturally comes with obvious ethical, practical, and safety concerns. 

Instead, astronauts have relied on a remarkably low-tech method of trash disposal. Crew members compress garbage with duct tape into bundles called “trash footballs,” which they later load onto cargo ships such as the Russian Progress or Northrop Grumman’s Cygnus. These ships then jettison the trash, leaving it to burn up during reentry into Earth’s atmosphere. 

In 2022, the ISS developed a new, more efficient waste disposal method. By connecting a special waste container with a capacity of 600 pounds to an airlock, this system allows astronauts to store and dispose of larger amounts of trash. The whole container is launched from the station directly into Earth’s orbit, where it also burns up on reentry — with no cargo ships needed and no junk left in space.

Window Cleaning

You won’t find many better views than those from the windows of the ISS — but just like here on Earth, those windows need to be wiped down from time to time. Inside the station, astronauts regularly clean windows using alcohol-based wipes to remove fingerprints, condensation, and dust. But that’s the easy part. 

You may think that space, being a near-pristine vacuum, wouldn’t cloud the windows outside the station. And while the windows don’t become murky anywhere near as quickly as they do here on Earth, they do still need an occasional polish. Impacts from micrometeoroids and orbital debris, thruster firings from visiting spacecraft, and outgassing from the ISS can all leave particles that settle on the station’s exterior, including the windows. 

So the ISS windows do need to be cleaned, albeit infrequently. In 2015, for example, Russian cosmonauts took a five-and-a-half-hour spacewalk during which they wiped away grime that had accumulated on the portholes over a period of years — arguably the most extreme window-washing job imaginable.

Exercising

Free from Earth’s gravity, an astronaut’s bones and muscles can atrophy. On Earth, our bones and muscles constantly work against gravity to support our body weight, maintain posture, and help us move around. But in the microgravity of a space station, human bodies no longer need strong bones and muscles to function — so they adapt by breaking them down. 

Bones lose density because the signals telling them to rebuild cells have been removed, and muscles atrophy because they’re no longer working as hard as they do on Earth. To combat that, astronauts must exercise for about two hours per day during a long-duration mission. 

Crew members on the ISS use three exercise machines to stay in shape, which simulate weightlifting, cycling, and running. (NASA astronaut Sunita Williams even used the ISS treadmill to “complete” the Boston marathon from orbit.) 

Despite rigorous exercise programs, some astronauts still experience bone and muscle loss. It remains a critical area of research and technological innovation, especially considering future long-duration missions planned for the moon and Mars.

Maintenance and Repairs

Some of the most demanding chores on the ISS involve maintenance and repairs. Unlike space shuttles that return to Earth for servicing, the ISS never comes home, so astronauts must handle both preventive maintenance (inspection and replacement) and corrective maintenance (fixing broken equipment), which they train for on Earth before heading into orbit. 

Inside the station, astronauts repair everything from oxygen generators to water pumps and computer systems. They replace air filters, fix toilets, troubleshoot ventilation systems, and swap out failing components using spare parts stored aboard the ISS. 

The most dramatic and dangerous repairs are those that must be done outside the station. In 2007, for example, astronaut Scott Parazynski performed one of the most dangerous spacewalks in ISS history, riding on the end of a robotic arm to repair a torn solar panel. Any major repair, especially one outside the station, requires careful planning — and, sometimes, nerves of steel.

Some Chores Are Best Left on Earth

Some common chores aren’t done at all in space, either because they’re not required or because they’re simply too tricky to carry out. Doing laundry, for example, is a nonissue on the ISS. There’s no washing machine on the space station, primarily due to water constraints, so astronauts simply have a limited number of garments they wear again and again until they’re too smelly or dirty for further use (at which point they’re tossed in the trash). 

Cooking is another task that requires very little effort. There’s a permanent eight-day menu aboard the ISS, consisting of three meals and one snack a day — but it’s all prepackaged and preprepared, ready to be reheated or rehydrated in seconds (which also means there are no dishes to wash).

Aspiring astronauts in their teenage years can also breathe a sigh of relief, as there’s no need to make beds on the ISS. Sleeping in microgravity is a challenge, and there’s no real way to lie down, so astronauts instead tuck themselves into secured sleeping bags when it’s time to rest.

Humans aren’t the only creatures with distinct sleep habits. From horses that snooze standing up to elephants that barely rest more than two hours a night, the animal kingdom is full of fascinating sleep strategies. 

These habits often form out of necessity and are shaped by factors such as diet, predation risk, hunting patterns, and metabolism. Because of this, some species spend an impressive amount of time — even more than half their lives — asleep. Discover why certain animals, including penguins on Antarctica’s icy plains and sloths in the rainforests of Central America, spend more time catching zzzs than they do awake.

Parrotfish

Parrotfish are among the sleepiest fish, averaging around 13 hours of rest every night. During waking hours, they spend as much as 90% of their time eating algae growing on coral reefs. The fish inhabit tropical waters worldwide and grow to be 1 to 4 feet in length.

While most other fish choose sheltered spots to sleep in, parrotfish tend to sleep out in the open, though some hide in coral. But several larger species, such as the queen parrotfish (Scarus vetula), have a very unique sleep habit. 

To protect itself from pathogens and parasites, it wraps itself in a cocoon made of mucus secreted by a special gland. This self-made sleeping bag also blocks the fish’s scent from predators, such as moray eels.

When disturbed, the cocoon alerts the fish by acting as a sort of alarm clock, which it reacts to by swimming away as quickly as possible. This allows parrotfish to sleep for more extended periods than other fish. Moreover, many kinds of reef sharks are active at night, so remaining still and cocooned instead of wandering is safer for parrotfish.

Platypuses

Platypuses are an unusual species: They’re semi-aquatic, egg-laying mammals that also happen to be venomous, but these southern Australian natives are perhaps best known for their duck-like bills. Those bills are utilitarian, aiding platypuses as they hunt for crustaceans during most of their waking hours. This high-calorie diet enables them to sleep for up to 14 hours a day. 

Not only do platypuses sleep a lot, but they also spend more time in REM sleep than any other mammal. Mammalian sleep cycles are split into two stages, REM (rapid eye movement) sleep and non-REM sleep. Researchers have found that platypuses spend a lot of time in REM sleep — more than eight hours per day. 

That’s nearly 60% of its daily sleep, which is a hefty amount, considering humans spend only around 25% of sleep time in REM. Because platypuses are an ancient species, experts believe that unusual pattern may reflect an early stage in the evolution of sleep, before REM sleep was segregated from SWS (slow-wave sleep) in the brains of animals. 

Since dreaming occurs during REM, we can’t help but wonder: What do platypuses dream about? Perhaps hunting for shellfish in the streams of Tasmania.

Three-Toed Sloths

The world’s slowest mammal is also one of its soundest sleepers. Three-toed sloths sleep between 15 and 20 hours daily, usually while hanging from tree branches. Even during waking hours, they barely move, mostly shifting positions or slowly foraging. 

At night, they wake for a few hours to eat leaves, shoots, and fruit from the trees they reside in. However, those meals can take up to one month to be fully digested. Due to their extremely slow metabolic rate (40–74% slower than that of other mammals of their size), sloths have less energy than most mammals and therefore require much more sleep. 

Sloths are so stationary, in fact, that algae tends to grow on their fur. Conveniently, this greenish tint provides the slow-moving animal with much-needed camouflage in the rainforest canopy. Native to Central and South America, these gentle mammals rely on trees for safety from large predators, especially big cats, making their arboreal lifestyle essential to their survival.

Owl Monkeys

Owl monkeys (Aotus trivirgatus) are the world’s only nocturnal species of New World monkey (the five families of primates found in the Americas). Also known as the “northern night monkey” or “three-striped night monkey,” this South American native requires lots of rest, nearly 17 hours a day. 

The owl monkey is a rather diminutive species, measuring 11 to 15 inches long and weighing less than 2 pounds. Nocturnal predators don’t usually eat owl monkeys, so it’s more important for them to remain hidden from daylight predators who pose a greater danger. 

Most active at dawn and dusk, owl monkeys live high in the forest canopy of Venezuela and Brazil. During the day, they sleep in the holes of trees or among dense foliage. Their eyes are larger and rounder than those of most other primates, enabling them to see better at night by taking in more moonlight. 

They’re most active during the wet season, when fruit is abundant, and they tend to sleep and rest more during the dry season, when food is scarce. Due to their alternative sleep schedules, owl monkeys don’t compete with other larger primates for the same resources  — another key reason for their long daytime slumbers.

Tigers

Tigers, the largest members of the cat family (Felidae), can measure up to 13 feet long and weigh up to 660 pounds, and they require more rest than smaller felines. There are six subspecies of tigers, all of which share many similarities, including the need to get about 18 to 20 hours of sleep daily.

Tigers spend all this time sleeping so they can conserve as much energy as possible for their rigorous hunting habits. They prefer large prey, such as deer and wild boar, which require intense bursts of energy to take down. They often can’t finish their prey in one sitting, so they hide the carcasses and sleep nearby until they’re ready to feed again.

Koalas

One of Australia’s most famous residents is also one of the animal kingdom’s top snoozers. On average, koalas spend between 18 and 22 hours sleeping, primarily due to their diet. Koalas feed on up to 3 pounds daily of eucalyptus leaves. It’s a myth that these leaves get the marsupials “high,” but they do have a sedative effect.

Koalas’ digestive systems require more energy than those of most animals, because their intestinal pouches are full of symbiotic bacteria that slowly work to safely break down the eucalyptus leaves, which contain tannins and toxins most species can’t digest. This unique diet is also low in nutrients, which further decreases energy levels.

Ball Pythons

Most snake species tend to sleep for long stretches, but ball pythons take the title for most hours of shut-eye. They sleep for around 20 to 23 hours per day, but not all at once. Instead, they wake several times for short periods, primarily to readjust and check that their surroundings are secure. Conserving energy is common among predators such as snakes because they must get sufficient rest for their digestive systems to function properly after large meals.

Ball pythons are popular pets, yet it can be difficult to tell if they’re asleep or not because, like all snakes, they lack eyelids. They do, however, have a thin layer of skin on each eye called a “brille” that protects them from dirt and debris. This layer is invisible to the human eye, so it always appears as if the snake is awake, even though it’s very likely asleep.
