Human ingenuity knows no bounds—as these patents show.

1. REWARD CANDY DISPENSER

Patent: US 5823386 A
Published: 10/20/1998

As any multitasker knows, it can feel impossible to sit at a computer and focus on work that needs to get done. What if something happens on Facebook? How can you focus until you know who’s on the Wikipedia page of left-handed historical figures? To force concentration, many resort to draconian measures like limiting Internet use or (gasp!) going offline altogether. But the inventors of this tool tap into what behavioral scientists and kindergarten motivational speakers have long known: Treats get results.

The Reward Candy Dispenser for Personal Computers is positive reinforcement for desk jockeys. An optical sensor attaches to your screen to keep an eye on what you’re doing. When you achieve your target (say, sending that email or reading all the way through a long news story), a signal is sent to a container on your desk, and, as with a gumball machine, a single piece of candy is released into a chute. Want another? Get more work done! Lab-rat life never tasted so good.

2. LEAF GATHERING TROUSERS

Patent: US 6604245 B1
Published: 8/12/2003

With fall comes the ultimate scourge of lawn work: raking leaves. All of those gorgeous, oxygen-giving trees in your yard become instruments of torture, fiendishly littering their leafy bounty all over the lawn and sidewalk.

According to the inventor of the leaf pants, the leaves aren’t the problem. It’s the rake—that pronged horticultural nightmare that strains backs, blisters hands, and poses a real threat if left lying in tall grass. But a leaf blower isn’t the answer either. Instead, the inventor insists, what humanity needs is a method that is “compatible with the natural body movement of a person.”

Enter leaf chaps, a pair of zip-on flexible tubes that slip over pant legs with a net fastened between the two so you can gather leaves as you stroll. The net corrals the leaves and collects them in front of you, so with just a few extra steps, you’re forming piles that are easily picked up later. Not merely convenient, the chaps also promise to make you more productive. Rather than struggle with bulky tools, do something you’d be doing anyway (walking around your lawn), while getting work done! Sure, that walk is more like a waddle, but that’s the price you pay for innovation.

3. THE DAD SADDLE (AKA, THE DADDLE)

Patent: US 6241136 B1
Published: 6/5/2001

Attention, parents: Are your kids bored with the same old piggyback routine? Are you sick of getting sticky fingers in your hair every time you let them hitch a ride? Try the Dad Saddle. Paul R. Harriss, the inventor of this parental paraphernalia, noticed that while contraptions—from ergonomic backpacks to simple scarves—exist to help parents carry their babies, once the kids grow up, you’re forced to go bareback. Suffer no more! The Dad Saddle’s sturdy harness fastens around the waist and sports two pint-size stirrups for a child’s feet, “virtually eliminating the possibility of back strain.” Adjust the height of the stirrups so your little cowboy or cowgirl can hold steady. Then remind them to tip their hats before they tackle the open range.

4. THE CRISPY CEREAL SERVER

Patent: US 4986433 A
Published: 1/22/1991

From the moment John Harvey Kellogg created the first cornflake, people have been trying to solve the problem of soggy cereal. Turn your back on it for a moment too long, and even the crispiest flakes become a bowl of mush. Cereal makers can treat their products to keep them from absorbing milk, but that only delays the inevitable. But what if the solution were in the bowl itself? The ingenious Crispy Cereal Serving Piece and Method keeps your Froot Loops fresh until the very last minute, guaranteeing “the crispness of the cereal throughout even the most leisurely meal.” A bowl on the table holds just the right amount of milk, while a second bowl, holding the dry cereal, is suspended in the air by a sturdy chute. Send a spoonful down the chute into the milk when you’re ready to take a bite, and relax knowing that the rest of your breakfast is high and dry (literally).

5. THE GREENHOUSE HELMET

Patent: US 4605000 A
Published: 8/12/1986

Everyone knows there’s nothing like a walk outdoors for a breath of fresh air. But in a hectic, urban life, you may be too busy to plan a nature walk—let alone one around the corner. Not to worry: The greenhouse helmet will bring nature to you at a moment’s notice. All you need to do is strap it to your face! A self-enclosed, anti-fog-treated dome sits over the wearer’s head, containing multiple shelves to hold tiny plants inside. As you exhale, the plants soak up the carbon dioxide, supposedly stocking you in return with the purest oxygen money can buy. The helmet even has a two-way intercom system, so you can communicate with friends in the not-so-great outdoors. Now, no matter where you are, the air will always be as fresh as a daisy. Have fun watering your head, though.

6. REALLY COOL SHOES

Patent: US 5375430 A
Published: 12/27/1994

Late summer’s swelter is the perfect excuse for wannabe exhibitionists to strip down to fashion’s bare minimum, from top to toe. But for those whose tootsies are less than sandal-ready, one ingenious inventor came up with a solution: air conditioned shoes. As you step, a series of chambers in the heel contract like mini-bellows, exerting force on a set of coolant-filled coils that turn the ambient heat into chilled air. That air is then expelled through a pad running under the foot, literally cooling your heels. And with a quick switcheroo, the cooling chambers reverse their function, becoming a foot warmer for winter months. Finally, a shoe for all seasons.

7. THE AUTOMATIC PET PETTER

Patent: US 20060207518 A1
Published: 9/21/2006

As any kid with a puppy knows, pets are a lot of work. They need food, exercise, grooming, poop scooping, and hardest of all: nonstop physical affection. Thankfully, inventor Anthony Steffen created a machine to make life easier. The automatic dog petter not only strokes your pup (or feline) with a mechanical hand; it also plays audio so you can provide your furry friend with a comforting pep talk or their preferred cover of “Hound Dog.” Fido need only stand on a motion-sensor platform, and it’s just like you’re there with him. As Patent 20,060,207,518 reminds us, “It is a fact of modern life that most people work away from their homes. If they have pets, these pets will often be alone for many hours.” This may be a fact of modern life, but so are robots, and both you and Fido will be better for it.

8. SLED-FREE SLEDDING/SLED PANTS

Patent: US 5573256 A
Published: 11/12/1996

Little is more exhilarating than zipping down a snow-covered hill. And little is more humbling that trudging back to the top, toboggan in tow. That breathless, awkward, sweaty climb is the conundrum that Patent 5,573,256 seeks to solve. “Until now, a sled capable of being attached to the body of the user and worn before, during, and after a downhill sled run has not been invented,” writes inventor Brent Farley. Fortunately for us, he fixed that. His liberating contraption allows you to simply strap sled chaps to your snow pants and enjoy ride after unencumbered ride.

9. THE BANANA SUITCASE

Patent: US 6612440 B1
Published: 2003

It’s snack o’clock and your banana got horribly bruised in your bag on the way to work. What now? Stale party mix from the break-room vending machine again? Thick skins notwithstanding, bananas are subject to all manner of abuse, but the Banana Suitcase keeps your favorite fruit safe and fresh as it travels in this perforated, foam-lined case that hinges shut. That is, as long as it fits into this one-size-only carrying case! No wonder the invention didn’t exactly peel off.

10. THE GERBIL VEST

Patent: US 5901666 A
Published: 5/11/1999

Thanks to this clever invention, you can make your guinea pig live up to its name. Or you can take your hamster grocery shopping, bring your chinchilla on a morning jog, or sign that bank loan with your gerbil’s moral support. The technology is simple: “A vest or belt is integrally formed with tubular, pet-receiving passageways that extend around the wearer’s body and terminate in pocket-like chambers,” the patent says. “Outer wall portions of the passageway are transparent so that a pet moving along the passageways can be seen by a spectator.” The pet display vest is not available in all, or frankly any, stores.

There is no other helicopter in the world like Marine One, the president’s No. 1 getaway vehicle. It’s as first-class as a helicopter can get.

 René Descartes once described the pineal gland as “the principal seat of the soul.” Though medical knowledge has vastly progressed since then, here are a few things you might not have known about this critical organ.

1. IT’S BEEN RECOGNIZED AS IMPORTANT SINCE THE ANCIENT GREEKS.

Though the pineal gland wouldn’t be fully understood until the 20th century, descriptions of its anatomical location are included in the writings of Galen (ca. 130-ca. 210 CE), a Greek doctor and philosopher.

2. ITS SHAPE INFLUENCED ITS NAME.

This itty-bitty little gland, located very deep in the center of the brain, gets its name from its pinecone-like shape, most recently from the French (pinéal, or “like a pinecone”), itself from the Latin for pinecone (pinea). However, at about one-third of an inch long in adults, it’s smaller than your average pinecone.

3. THE PINEAL GLAND IS PART OF YOUR ENDOCRINE SYSTEM.

Though located in your brain, the pineal gland is actually a crucial part of your endocrine system, which regulates major bodily processes such as growth, metabolism, and sexual development through the release and control of hormones.

4. IT CONNECTS THE ENDOCRINE AND NERVOUS SYSTEMS.

The gland translates nerve signals from the sympathetic nervous system into hormone signals.

5. THE PINEAL GLAND WAS LONG CONSIDERED MYSTERIOUS.

Because the pineal gland was the last of the endocrine structures to be discovered, scientists considered it a mysterious organ. Today, we know that unlike much of the rest of the brain, the pineal gland is not isolated from the body by the blood-brain barrier system.

6. DESCARTES WAS WRONG ABOUT ITS RELATIONSHIP TO THE MIND, THE SOUL …

The 16th-century French philosopher and mathematician René Descartes was fascinated with the pineal gland, considering it “the place in which all our thoughts are formed.” Scientists now credit that function to the neocortex.

7. …AND TINY ANIMAL SPIRITS IN THE BRAIN.

Descartes thought that within the pineal gland, tiny animal spirits were like “a very fine wind, or rather a very lively and pure flame,” feeding life into the many small arteries that surround the gland. This was likely due to his abysmal understanding of anatomy and physiology.

8. IT’S BEEN CALLED THE “THIRD EYE.”

The pineal gland was commonly dubbed the “third eye” for many reasons, including its location deep in the center of the brain and its connection to light. Mystic and esoteric spiritual traditions suggest it serves as a metaphysical connection between the physical and spiritual worlds.

9. IN REALITY, IT PRODUCES A SINGLE—BUT KEY—HORMONE.

As scientists have learned more about the functions of the pineal gland, they’ve learned it synthesizes the hormone melatonin from the neurotransmitter serotonin. Melatonin production determines your sleep-wake cycles and is purely determined by the detection of light and dark. The retina sends these signals to a brain region known as the hypothalamus, which passes them on to the pineal gland. The more light your brain detects, the less melatonin it produces, and vice versa. Melatonin levels are highest at night to help us sleep.

10. MELATONIN IS ALSO CRITICALLY INVOLVED IN REPRODUCTION.

Melatonin inhibits the release of pituitary reproductive hormones, known as gonadotropins, from the pituitary gland, affecting male and female reproductive organs. In this way, melatonin—and therefore the pineal gland—regulates sexual development.

If 2016 didn’t fill your need for retro gaming with the release of the NES Classic Edition, 2017 could do the trick with the return of a beloved old school franchise: Double Dragon. To celebrate the franchise’s 30th anniversary, Arc System Works—which bought the rights to the series in 2015—is set to release Double Dragon IV on January 30 on both Playstation 4 and Steam, The Verge reports.

Unlike modern revivals of older franchises—like the recent Tomb Raider and Doom reboots—Double Dragon IV is sticking to its retro graphics and low-fi gameplay roots. Billy and Jimmy are yet again pixelated crime fighters forced to go through stage after stage of enemies, just like they were back in 1987. Arc System Works even hired the producer, director, character designer, and composer of the original Double Dragon to return for IV.

The last time Double Dragon had a numbered sequel in the beat-’em-up genre was 1990’s Double Dragon 3: The Rosetta Stone. After that was Super Double Dragon in 1992 and Double Dragon V in 1994, which was actually an ill-conceived Street Fighter II clone. Outside of a return to the franchise’s roots and the fact that it will have a two-player duel mode, not much is known about Double Dragon IV. But with a release date looming, expect Arc System Works to unveil more in the coming weeks.

Why do rockets need so much fuel if, in space, there is nothing to slow them down once they are up to speed?

Robert Frost:

The propellant is primarily needed to get the spacecraft into orbit, not to stay in orbit.

In the above picture, you can see an illustration of a mission to the Moon. Rockets are conventionally built to have multiple stages. This is done because so much fuel is needed to get a payload from the surface to orbital altitude and accelerated to orbital speed. When about half the propellant is burned, the bottom half of the rocket is jettisoned. This makes the remaining rocket considerably lighter, which means when the engines in the next stage ignite, they will have a greater effect. The same can happen again when that next stage runs out of fuel. Eventually, all that’s left is the payload, traveling in the desired orbit. If that payload is carrying fuel, it is because it might have to do some other maneuver, such as a retro-fire to come home or a burn to transfer to another orbit, or it might need to control its attitude using small reaction control jets.

Own a car long enough and you will eventually find yourself standing in an auto repair shop trying to decipher what the technician is trying to tell you. The only common language? How much it’s going to cost.

Even though you might not understand all the nuts and bolts of a repair job, it’s still important you have enough information to make an informed decision. We asked mechanic Charles Sanville of The Humble Mechanic blog to pass along five simple questions that should elicit some helpful information from a repairman before (and after) you commit to getting the work done.

1. “CAN YOU SHOW ME THE PROBLEM?”

Most mechanics are not out to rip you off. But if they are, they can often be tripped up by a simple request to see which part is in need of attention. “You always want to ask this,” Sanville says. “Tell them you want to see the part that’s failing.” While some issues might be with a car’s electronics and therefore won’t have a physical spot to point to, it’s still a good idea to try. Having a visual aid will also make a tech’s explanation easier to understand.

2. “WHAT HAPPENS IF I DON’T FIX THIS?”

Be sure to ask the shop what the consequences might be of not taking care of an issue right away. “You should ask what happens in the long term if something doesn’t get fixed,” Sanville says. While a timing belt might need replacement, it’s possible it might be good for another few thousand miles; a brake issue probably can’t wait.

3. “CAN YOU PRIORITIZE THESE REPAIRS?”

Some technicians make repairs seem like urgent matters, but not everything needs to be addressed immediately. “Having five issues isn’t uncommon, but a couple of them might not be a big deal and can wait,” Sanville says. “Have them prioritize what’s wrong with the car.”

4. “CAN I SEE THE DEFECTIVE PART?”

Before the repair has been made, request that the shop save the faulty part so you can take a look. “Sometimes they’ll let you keep it,” Sanville says, depending on disposal requirements. It’s tangible proof they did the work promised.

5. “CAN YOU EXPLAIN HOW YOU FIXED IT?”

Don’t worry about understanding much—or any—detail about the repair work. What you really want, Sanville says, is to build a relationship with the technician and not just the service advisor behind the counter. “Ask them to explain in a technical way what the problem was, how they caught it, and how it was fixed. It’ll help build a relationship and then you’ll have your own tech. You can bring it to ‘Bill’ instead of just ‘ABC Auto.’ That’s a guy who will know you and know your car and do what he can to keep you on the road.”

Some prayers might make reference to wine, but they certainly don’t talk about Hennessy. Or emptying clips. Or, well, pretty much anything else found in Tupac Shakur’s 1996 song “Hail Mary.” But that wasn’t enough to stop one church in Sri Lanka from accidentally distributing the lyrics to the rap song instead of the Catholic prayer of the same name, CNN reports.

The lyrics were included in a booklet of prayers for the church’s Christmas carol service in the capital city of Colombo on December 11 and were immediately identified (and tweeted) by several people attending. The book, by the way, advertised the event as “A Festival of Music for Peace & Harmony” so a line like “F— the world if they can’t adjust, it’s just as well, Hail Mary” is going to raise some eyebrows:

Instead of opening the booklet to the familiar refrain of “Hail Mary, full of grace. The Lord is with thee,” devotees were greeted by words of wisdom from Tupac like, “Makaveli in this, Killuminati, all through your body. The blow’s like a twelve gauge shotty, feel me.”

“A lot of people were in shock as [to] whether it was a joke or someone would actually rap the song,” churchgoer Andrew Choksy told CNN. “A few of the older ladies in front of us could not stop looking at the printed booklet.”

The booklet was apparently prepared by a young boy, who had simply downloaded the wrong version of “Hail Mary” from the internet, somehow glossing over lines like “Come with me, Hail Mary/Run quick see, what do we have here/Now, do you wanna ride or die?”

The error was caught soon after the books were distributed, according to Father Da Silva, from the Archdiocese of Colombo. “The page was in the middle of the booklet. When people looked at this page, they saw it before the start of the show. Two people saw it and alerted us to it,” he told CNN.
