A new line of high-tech earplugs called Knops promises to grant wearers the gift of selective hearing. According to The Verge, the plugs can be adjusted to filter out background noises ranging from low to high.

Tiny knobs positioned on the sides of the earplugs allow wearers to switch between four “hearing” settings: no filter; an ambient noise blocker, which filters city sounds; a setting meant for live music; and a fourth one designed for silence. Wearers can keep their Knops in all day, allowing them to hear what they want, when they want.

Knops plans to bring their product to the masses by November 2018, following a successful (and still ongoing) Kickstarter campaign. The earplugs range in price from $62 to $117, and come in a variety of different colors and trims. Individuals who support the project can score their own set of Knops for a special price before the campaign ends on May 4.

How Thomas Edison Jr. Shamed the Family Name

Image credit:

Consumption. Rheumatism. Kidney trouble. Lost manhood. Womb displacement. Nagging congestion. Lady troubles. No matter what the ailment, magazine and newspaper readers in 1903 saw they had the ability to obtain a device that was presented as a modern medical marvel. It was called the Magno-Electric Vitalizer, and it harnessed the power of electricity to stimulate the nerves, inciting the body’s own natural healing powers.

But that wasn’t all the Vitalizer could do. In rigorous “scientific” study, the device—which consisted of two copper plates that could be applied to the head or torso, with optional nose plugs—was found to improve mental function, allowing test subjects to respond to difficult questions five to 10 seconds faster than the control group. One ad in the Los Angeles Herald promised that the Vitalizer “enabled the wearer to think much more quicker.”

Like a lot of dubious-sounding health devices peddled at the turn of the 20th century, the Vitalizer was complete bunk. The United States Patent Office rejected an application for it on two separate occasions because it was “inoperable.” By 1904, the U.S. Postal Service charged its distributor with postal fraud.

Quackery was nothing new, of course. But the Vitalizer’s exploitation of the public desire to cure their ills was unique. It was sold by the Thomas A. Edison Jr. Chemical Company, an outfit ostensibly owned by the son of famed inventor Thomas Edison. The family name had become synonymous with innovation; most people found it easy to believe the so-called “Wizard” had offspring who could deliver similar life-altering technology to the masses. (One ad read that the elder Edison “could not accomplish everything, and he left one room in the House of Science in which Thomas A. Edison, Jr. has labored and experimented for years in perfecting the Magno-Electric Vitalizer.”)

In reality, Thomas Edison Jr. had very little in common with his famous father. Rather than hone his craftsmanship, he preferred to sell his last name to a series of unsavory and unprincipled businesses. The practice so bothered his father that he once told a friend that his son was “absolutely illiterate, scientifically and otherwise.”

No mention of the senior Edison seems complete without crediting his most impressive contributions to the world. In 1877, he used his phonograph machine to record “Mary Had a Little Lamb” on a piece of tinfoil, introducing the first voice recorder/player. He ushered in the era of modern electricity, perfecting the incandescent light bulb and championing a system that would wire homes to power grids. From his laboratory in West Orange, New Jersey, Edison developed more than half of the 1093 patents he was granted during his lifetime.

Edison was married twice, once to Mary Stilwell from 1871 to 1884 and again to Mina Miller in 1886. Edison loved Morse Code: He proposed to Mina by tapping out the words. Of his six children, he nicknamed daughter Marion “Dot” after the messaging system. Thomas Jr., who was born in 1876, was “Dash.”

Some accounts of Edison’s parenting approach are less than flattering. With daughter Madeline, he’d reportedly present impromptu quizzes at the breakfast table and apply a hot spoon to the back of her hand if she answered too slowly, or incorrectly. Edison’s kids were issued a daily quota of encyclopedia-reading and other intellectual tasks.

It’s believed that Thomas Jr. found this environment to be oppressive, having neither the ambition nor the aptitude to sharpen his mind with formal education. He dropped out of an elite prep school at age 17 before earning his diploma, prompting his father to observe that his son desired fame more than a sense of actual accomplishment.

In 1898, Thomas Jr. settled in New York. He was the subject of a flattering newspaper profile that appeared to do little in the way of fact-checking, particularly over claims that the younger Edison had invented a better light bulb. (He had not.) The publicity led to a high-profile appearance at an electrical exhibition at Madison Square Garden that same year. Although he had no real responsibilities—he was put in charge of the decorating committee—Thomas Jr. held court with journalists and presented himself as an inventor on the cusp of major breakthroughs at the risk of his own life.

“I never expect to die a natural death,” he told reporters. “I feel confident I will be blown up some day.”

Despite his lack of laboratory experience, Thomas Jr. knew his last name held considerable value. Thanks to both the press he received in New York and the name on his birth certificate, Edison was able to entice individuals to invest in a series of ill-conceived ventures. In 1901, he peddled “Wizard Ink” tablets, a very deliberate way of invoking his father’s nickname. The globs of ink could be plopped in an ounce of water without “clot, lump, or sediment.” Ads claimed the ink had been tested in leading banks.

If the elder Edison fumed at his nickname being used to market unremarkable writing tools, the Vitalizer would soon send him over the edge. A totally useless fabrication, the device capitalized on the public’s fascination with electricity and was said to deliver mild impulses via the head or back. Thomas Jr. asserted that it had been tested on second graders to promote intellect, could provide relief from menstrual pain, and would clear clogged nasal passages. “There seems to be no limit to its sphere of action,” the ad copy read.

Once received, the Vitalizer’s instructions promised relief from virtually any disorder or complaint of which the user could conceive. Depending on the issue, the Vitalizer could be positioned over any major organ. For problems related to one’s genitalia, it promised to be “the only sure and sensible cure.”

Anyone who ordered the $8 Vitalizer was only relieved of both their money and any hope of assistance. By 1904, at the behest of his father, the Post Office had successfully ordered Thomas Jr. to halt shipments of the product. Although the younger Edison was probably just selling a name and had nothing to do with the company itself, his father bemoaned to LIFE magazine that such use of his name was causing him terrible grief.

“I am thinking of a scheme to prevent persons from using the name I have striven honorably to protect,” Edison said.

Fed up with Thomas Jr.’s ventures, Edison offered to pay his wayward son a $35 per week allowance if he would simply change his name. He agreed, and began calling himself Thomas Willard. The senior Edison then set him up on a mushroom farm with the hope that he would eventually become self-sufficient.

Instead, Thomas Jr. wound up in a sanitarium.

It’s not known whether the pressure of being Thomas Edison’s namesake led to Thomas Jr.’s personal struggles. According to his second wife, he abused alcohol and was briefly admitted into a mental institution to address his depression. The mushroom farm provided only modest financial relief, so Edison raised his allowance to $50 a week.

At some point, Thomas Jr. decided he wanted to live up to the family name and spent seven years trying to perfect his Ecometer, an automobile addition that would help conserve fuel. At the same time, his father was toiling on efforts to perfect an electric car with Henry Ford; it’s believed Ford subjected the Ecometer to a battery of tests so that he wouldn’t risk offending Edison.

Thomas Jr. dreamed of his invention being installed in every car in the nation. It failed to pass basic performance tests.

When Thomas Edison died in 1931, he left his son a seat on his company’s board of directors. While it provided some measure of monetary relief, the success was short-lived: Thomas Jr. died in 1935, allegedly due in part to his substance abuse issues.

Despite his efforts, Thomas Jr. remains little more than a footnote in accounts of Edison’s life—the selfish, attention-seeking son who resented living in the shadow of his famous father and used any means available to him in order to escape it. Unless, of course, he could profit from it.

Before the Vitalizer was pulled from the market, Thomas Jr. asserted that he was putting the public’s health first and claimed he turned down a $750,000 offer to buy his company. “I am determined,” he said, “that this invention shall not fall into the hands of those who would regard it only as a money-making business.”

Social Media Can Push Runners to Improve Their Performance

filed under: exercise

Sometimes peer pressure works in our favor. According to a new study published in Nature Communications, the running habits of our peers have a direct impact on how hard we push ourselves in our own regimens. And this effect isn’t limited to friends in the neighborhood: Virtual pals can also motivate us to catch up to their level.

As the Los Angeles Times reports, the study was conducted by MIT researchers looking at data from 1.1 million users on a social fitness app. After users went for a run, their stats were shared online for others in their network to see. The researchers found that after seeing that a friend had added 10 minutes to their run that day, users extended their own runs by three additional minutes, on average. That same pattern carried over to other measures of performance: When one user ran an extra kilometer, their friend ran an extra 0.3 kilometers; when one user burned 10 more calories than normal, their friend burned an additional 3.5.

To further investigate their theory that exercise is contagious, the researchers threw weather into the mix. If peer pressure is really that strong a motivator, they surmised that the effects of nice weather should be felt by members of the network living in places with less ideal conditions. Their hunch was correct: If a sunny day in St. Louis pushes people to stay outside longer, users in Seattle will see that and leave the house even if it’s raining.

Runners are also more likely to compare themselves to users of their own gender. A male runner is moderately motivated to compete with high-performing women, and strongly motivated to keep up with high-performing men. Women, on the other hand, are only motivated by other women and ignore the stats of men.

Runners looking to exploit the powers of remote running buddies have plenty of places to find them. As the study shows, running apps are a useful tool for connecting with friends. There are also virtual themed running clubs for those who like to mix pop culture with their cardio.

Nintendo May Release an SNES Classic

It’s been an interesting time for Nintendo. In 2016, the company appeared to be blindsided by the demand for its NES Classic, a palm-sized Nintendo Entertainment System pre-loaded with 30 games. Even though all its titles were decades old, the $60 console sold for hundreds of dollars due to a lack of supply and a surplus of nostalgia that created a secondary market. Then, Nintendo announced they were discontinuing the item, with final shipments arriving at retailers through the end of April.

One possible reason why: The company may be looking to replace it with an SNES Classic.

According to Eurogamer, Nintendo has initiated development of a reissued Super Nintendo Entertainment System that will share the NES Classic’s tiny chassis and pre-loaded game selection. (Hopefully without the accompanying fits of rage from gamers unable to get their hands on one without paying a huge mark-up.) The Super Nintendo was released in the U.S. in 1991. Fueled by the popularity of titles like Super Mario Kart, Donkey Kong Country, and others, it went on to sell 49 million systems worldwide.

Nintendo has yet to issue any official statement on the SNES Classic. Instead, the company is putting their promotional weight behind the release of the Switch, their portable console that debuted in March.

Why Are Dairy Queen Blizzards Served Upside Down?

Dairy Queen

It’s part lactose performance art, part boastfulness, and mostly awkward. Walk into any one of Dairy Queen’s 6000-plus U.S. locations (or up to a window) and there’s a very good chance your server will hand you a Blizzard—their soft serve treat packed with chunks of candy, cookies, baked goods, or fruit—upside-down, the spoon handle facing the floor.

A ritual since the national debut of the dessert in 1985, the eccentric hand-off has been questioned, puzzled over, and was even part of a nationwide promotion in 2016: If an employee failed to adhere to the policy, customers received a coupon for a free Blizzard. (Many outposts still offer a free Blizzard if yours isn’t served upside down, but it’s up to each franchise owner to determine whether or not it’s a standard policy.)

If you’ve ever wondered why they do it, you can credit an obnoxious 14-year-old kid in St. Louis.

Like most restaurant chains, Dairy Queen has often relied on its franchisees to help shape its menu. Founded in 1940 to capitalize on the soft serve ice cream phenomenon, the brand was fortunate enough to attract the attention of St. Louis businessman Sam Temperato, who owned dozens of locations and proved to be a steady fountain of ideas. His Full Meal Deal, which packaged a burger, fries, drink, and sundae for one flat price, was a hit. So was his notion to add chili dogs to the menu’s lineup.

In the 1970s, Temperato took notice of a custard stand operated by Ted Drewes Jr., a locally-owned operation that managed to hold its own against the marketing onslaught of Temperato’s Dairy Queen by peddling frozen treats Drewes referred to as “concrete,” ultra-thick shakes with bits of fruit mixed in. Drewes served them upside-down to customers to prove it wasn’t some watered-down concoction. The glob of custard was so dense it would hold the spoon in place and remain inside the serving cup.

That finishing touch was the result of a run-in Drewes had with 14-year-old customer Steve Gamber back in 1959. Gamber had been biking to Drewes’s stand for a sandwich and chocolate malt nearly every day. Each time, he’d demand Drewes make the malt thicker.

Finally, “just to shut me up,” Gamber recalled, Drewes handed him a malt so solid he could turn it upside down without risking spillage. “Is that thick enough for you?” Drewes asked.

This practice did not escape the attention of Temperato, who went to Dairy Queen executives in 1983 with the idea for a soft serve concoction made with fruit or crunched-up candy bar chunks, a practice he had seen in another local stand called Huckleberry’s. (Drewes refused to use candy in his custards.) After executives visited St. Louis and saw the lines at Drewes’s locations, they signed off on the Blizzard, using a trademarked name they had owned since the 1950s.

At the time, the thought of candy mixed with soft serve was a novel concept, and not one that was met with total enthusiasm. Mars, which owns the M&Ms and Snickers candy brands, refused to ship Dairy Queen broken-up pieces for the Blizzard; so did Oreo. But once Dairy Queen rang up sales of nearly 100 million Blizzards in 1985 alone, the brands had a change of heart. Blizzards have been a staple of Dairy Queen’s menu ever since.

Temperato, who freely admitted the inspiration he derived from both Drewes and Huckleberry’s, was showered with praise for boosting company revenues by 15 to 17 percent. The McDonald’s McFlurry and Friendly’s Cyclone followed, both attempting to capitalize on the frozen phenomenon. But only the Blizzard—born of “concrete” custard—is served upside down.

The University of Tennessee Offers a Dolly Parton-Themed History Class

Image credit:

Dolly Parton’s life is a true rags-to-riches story: Raised in poverty in rural Tennessee, she beat the odds and rose to international stardom as a country musician, actress, producer, and philanthropist. Now, The New York Times reports that the Southern star’s down-home roots are the focus of an honors history course offered at the University of Tennessee’s main campus in Knoxville.

Called “Dolly’s America,” the seminar uses Parton’s personal journey as a lens through which to examine modern Appalachian culture. The singer grew up in Sevier County, about 30 miles outside of Knoxville, and the class looks at how a “‘hillbilly’ girl from Appalachia grew up to become an international one-word sensation,” according to the course description on the university’s website.

Materials include Dolly Parton’s 1994 autobiography, Dolly: My Life and Other Unfinished Business, and books about Appalachia; movies, TV shows, and historic videos; and scholarly articles. Ranging from lighthearted to somber, they provide a framework for students to examine historic themes like child labor, regional poverty, and the federal-state committee formed by President Kennedy that’s known today as the President’s Appalachian Regional Commission.

“Dolly’s America” also tries to dispel deep-seated stereotypes about rural America: ”Reading about how hillbillies and feuds began as made-up characters and tropes in novels and cartoons to the rise of hillbilly music to Christian entertainment and the thread of tourism, students see the processes by which fiction often becomes fact, and how heritage is a blend of the real and the imagined,” the course description says.

“Dolly’s America” was taught for the first time last year, and will be taught again in Fall 2017. That said, admission is likely to be competitive, as the course recently received a Twitter endorsement by Parton herself:

11 Easy Ways to Be Greener on Earth Day

filed under: tips
Image credit:

Kermit got it all wrong: It is easy being green. Going green doesn’t have to mean committing to a 10-mile walk to work or abiding by “if it’s yellow, let it mellow”—you can make a difference by making small adjustments that add up to big change. Here are 11 ideas to get you started.

1. USE YOUR DISHWASHER.

It may seem counterintuitive, but your dishwasher is way more energy- and water-efficient at washing dishes than you are, as long as you’re running a full dishwasher. According to one German study, dishwashers use half of the energy and a sixth of the water, not to mention less soap. So, don’t feel guilty about skipping the sink of sudsy water, or about not pre-rinsing before loading up the machine—you’re actually doing the environment a favor by firing up your dishwasher.

2. SWITCH TO ONLINE BILL PAY.

Not only is it convenient to pay all of your bills with a click or two, it’s also environmentally friendly. One study found that the average U.S. household receives 19 bills and statements from credit card companies, banks, and utilities every month. By switching to online statements and online bill pay, each American household could save 6.6 pounds of paper per year, save 0.08 trees, and not produce 171 pounds of greenhouse gasses. Not bad for simply clicking a few “receive online statements” boxes.

3. OPT OUT OF JUNK MAIL.

While you’re paring down the amount of stuff that arrives daily in your mailbox, visit Catalog Choice to opt out of various mailers you don’t want to receive. So far, the nonprofit organization says they have saved more than 500,000 trees, over one billion pounds of greenhouse gas, more than 400 million pounds of solid waste, and approximately 3.5 billion gallons of water.

4. PLANT A TREE OR TWO.

Planting trees is obviously great for the environment, but if you’re strategic about it, it can help you reduce your energy costs and use less fossil fuel. According to ArborDay.org, planting large deciduous trees on the east, west, and northwest sides of your house can shade and cool your home during the warmer months, even slashing your air conditioning costs by up to 35 percent.

5. TURN OFF THE TAP.

If you leave the tap running while you tend to your pearly whites, you’re wasting approximately 200 gallons of water a month. Just turn the tap on when you need to wet your brush or rinse, instead of letting H20 pour uselessly down the drain. The same goes for anyone who shaves with the water running.

6. GO THRIFTING.

Take some advice from your old pal Macklemore and hit up some thrift shops—and that goes for whether you’re getting rid of clutter or adding more to your home. Buying and donating to thrift stores and second-hand shops means you’re recycling, supporting your local economy, and saving money. In fact, by some estimates, every item of clothing donated reduces 27 pounds of carbon emissions.

7. GET A HOUSEPLANT.

And grab a little guy for your desk at work, too. House plants and desk plants have been proven to improve your mood and raise productivity, but they also purify the air by removing volatile organic compounds (VOCs) found in homes and offices. They also absorb carbon dioxide and increase the humidity. Low-maintenance plants include pothos, spider plants, jade, various succulents, and peace lilies.

8. GET SCRAPPY.

Cut up paper that has only been used on one side and use it to scribble reminders, notes, grocery lists, etc. Or flip it over for any kids you know to color on. (You can color on it, too, if you want.)

9. PUT YOUR CAFFEINE TO WORK.

Your coffee likely traveled thousands of miles to arrive in your pantry, so get good use out of it. Use your grounds to mulch plants that love acidic soil, like roses, evergreens, and rhododendrons. If your garden problems tend to be less about the dirt and more about the things that live in it, certain garden denizens hate coffee—namely ants, slugs, and snails. Sprinkle grounds in problem areas to deter them.

10. ENLIGHTEN YOURSELF.

Compact fluorescent bulbs (CFLs—the spiral light bulbs) may cost more upfront, but they’ll save up to $57 over the life of the bulb. More importantly, they use 70 percent less energy than traditional bulbs and installing them is as easy as screwing in a light bulb. (Insert joke here.)

11. MAKE TRACKS.

You don’t have to cut out your daily driving entirely, but when you only have a few blocks, or perhaps just a mile or two to travel and don’t need to transport anything bulky, consider walking or hopping on your bike. Walking 1.5 miles generates less than a quarter of the greenhouse gasses that are emitted by driving the same distance.
