8 of the Animal Kingdom’s Most Clever Problem Solvers

Who ever said Mr. Fix-it had to be human?

1. Crows Make Dining Utensils

They say humans are toolmakers, but crows may be just as handy. The birds are known to pry out grubs buried inside trees with twigs. They’ll then strip off the twig’s bark and bend the end, turning it into a hook to dig out food. (Humans are the only other animals that use hooks!)

2. Hyenas Are Brilliant Teammates

To test whether hyenas were team players, researchers built a rig with two dangling ropes. When both ropes were yanked at the same time, a trap door opened, revealing a stash of food. Not only did hyenas work together to pull the ropes, they did it without training (monkeys, on the other hand, needed lots of help from humans to pass the test). Experienced hyenas even taught rookies in their pack how to do it.

3. Bees Are Efficient Architects

Honeycombs are the most efficient structures in nature. They use the least amount of wax for their size, and the hexagonal design makes the structure amazingly strong. It took humans over 2000 years of puzzling to figure that out!

4. Cows Celebrate a Job Well Done

Research shows that cows can feel emotions like fear and anxiety (and they even worry about the future). Cows also love to fix problems. A 2004 study found that when young cows solve problems, their heart rates increase. They even jump and kick when arriving at a solution—telltale signs that cows love having Eureka moments as much as we do.

5. Clark’s Nutcrackers Are Nature’s Traveling Salesmen

Pretend it’s errand time. You have to visit the supermarket, the pharmacy, and three other stores. All five are at separate locations. What’s the most efficient way to get to each one? Mathematicians call this “the traveling salesman problem,” and it’s harder than you think—it can even stump our best computers. However, it’s a snap for Clark’s Nutcrackers. Each year, these birds collect thousands of pine nuts and bury them in small stashes. When they return to pick up the goodies, not only do they remember where everything is, they can also calculate the fastest route to get them.

6. Pigs Rock at Video Games

When scientists built a snout-controlled game in which pigs had to move a shape across a computer screen and match it with a corresponding shape, they were naturals—they even performed better than some monkeys. Pigs are so smart that European regulators require pig farmers to provide “mentally-stimulating activity” for their swine (boredom makes pigs aggressive), and researchers designed a special video game to keep European pigs busy.

7. Parrots Are Feathered Linguists

Parrots aren’t capable of language, but they are good at imitating it. A parrot named Alex actually learned 100 English words, many of which he picked up without the motivation of food. Amazingly, Alex was able to make up words, too (he called apples “Banerries”—a blend of bananas and cherries). One time, when another parrot mispronounced a word, Alex yelled, “Talk clearly!”

8. Pigeons Make For Great Game Show Contestants

When researchers mapped the brain of pigeons, they discovered the areas for long-term memory and problem solving were wired just like a human’s. Pigeons are also better at game shows than us—studies show that pigeons play Monty Hall at a significantly higher success rate than humans.

Kodak’s New Cameras Don't Just Take Photos—They Also Print Them

Snapping a photo and immediately sharing it on social media is definitely convenient, but there’s still something so satisfying about having the printed photo—like you’re actually holding the memory in your hands. Kodak’s new STEP cameras now offer the best of both worlds.

As its name implies, the Kodak STEP Instant Print Digital Camera, available for $70 on Amazon, lets you take a picture and print it out on that very same device. Not only do you get to skip the irksome process of uploading photos to your computer and printing them on your bulky, non-portable printer (or worse yet, having to wait for your local pharmacy to print them for you), but you never need to bother with ink cartridges or toner, either. The Kodak STEP comes with special 2-inch-by-3-inch printing paper inlaid with color crystals that bring your image to life. There’s also an adhesive layer on the back, so you can easily stick your photos to laptop covers, scrapbooks, or whatever else could use a little adornment.

For those of you who want to give your photos some added flair, you might like the Kodak STEP Touch, available for $130 from Amazon. It’s similar to the regular Kodak STEP, but the LCD touch screen allows you to edit your photos before you print them; you can also shoot short videos and even share your content straight to social media.

If you want to print photos from your smartphone gallery, there's the Kodak STEP Instant Mobile Photo Printer. This portable $80 printer connects to any iOS or Android device with Bluetooth capabilities and can print whatever photos you send to it.

The Kodak STEP Instant Mobile Photo Printer connects to an app that allows you to add filters and other effects to your photos. Kodak

All three Kodak STEP devices come with some of that magical printer paper, but you can order additional refills, too—a 20-sheet set costs $8 on Amazon.

The Reason Dogs Are Terrified of Thunderstorms—And How You Can Help

Deafening thunder can be a little scary even for a full-grown human who knows it’s harmless, so your dog’s terror is understandable. But why exactly do thunderstorms send so many of our pawed pals into a tailspin?

Many dogs are distressed by unexpected loud noises—a condition known as noise aversion, or noise phobia in more severe cases—and sudden thunderclaps fall into that category. What separates a wailing siren or fireworks show from a thunderstorm in a dog's mind, however, is that dogs may actually realize a thunderstorm is coming.

As National Geographic explains, not only can dogs easily see when the sky gets dark and feel when the wind picks up, but they can also perceive the shift in barometric pressure that occurs before a storm. The anxiety of knowing loud noise is on its way may upset your dog as much as the noise itself.

Static electricity could also add to this anxiety, especially for dogs with long and/or thick hair. Tufts University veterinary behaviorist Nicholas Dodman, who also co-founded the Center for Canine Behavior Studies, told National Geographic that a static shock when brushing up against metal may heighten your dog’s agitation during a storm.

It’s difficult to nail down why each dog despises thunderstorms. As Purina points out, one could simply be thrown off by a break from routine, while another may be most troubled by the lightning. In any case, there are ways to help calm your stressed pet.

If your dog’s favorite spot during a storm is in the bathroom, they could be trying to stay near smooth, static-less surfaces for fear of getting shocked. Suiting them up in an anti-static jacket or petting them down with anti-static dryer sheets may help.

You can also make a safe haven for your pup where they’ll be oblivious to signs of a storm. Purina behavior research scientist Ragen T.S. McGowan suggests draping a blanket over their crate, which can help muffle noise. For dogs that don’t use (or like) crates, a cozy room with drawn blinds and a white noise machine can work instead.

Consulting your veterinarian is a good idea, too; if your dog’s thunderstorm-related stress is really causing issues, an anti-anxiety prescription could be the best option.
