Wild Lizards Care What You're Wearing

Bad news, pals: Your mom isn't the only one judging your outfit. A recent study published in the journal PLOS One finds that wild animals—in this case, lizards—respond differently to humans depending on the color of their clothes.

It makes perfect sense, if you think about it. Animals rely on their color vision to find food, evade predators, and seduce their mates. From a survival standpoint, color is information, no matter who's wearing it.

Previous studies have found that some bird species with orange or red feathers are less afraid of people wearing orange and red. Would other brightly colored animals have a similar response?

To find out, evolutionary biologist Breanna Putman considered a lizard. The western fence lizard makes its home in the desert climes of the western United States. Both sexes are brown or black, but the males have vibrant blue patches on their bellies and throats, and some have shiny blue spots on their backs. When challenged, males do little push-ups to flex their blue scales and make them look even more impressive. Blue, then, was the color to beat.

Putnam headed out to two lizard hotspots, one at a public park in Los Angeles and another at a nearby nature reserve. The bird studies had only compared people wearing orange and red with people wearing dark gray, which means it's possible that the birds would have responded well to any bright color. So Putnam brought along four t-shirts: one each in dark blue, light blue, bright red, and gray. The dark blue shirt was a pretty close match to the color of the male lizards' macho patches.

For each trial, Putnam put on a shirt, then tried to approach a lizard. At first, she merely walked casually toward them. After a few weeks of this, she switched and began trying to catch them. For every approach, she measured how close the lizard let her get, and how quickly and how far it ran away.

Sure enough, the dark-blue shirt seemed to put the lizards at ease, or at least more at ease than the rest of her wardrobe. While Putnam wore their favorite color, the lizards let her get twice as close (39 inches vs. 78 inches) than they did with other colors. They also didn't try very hard to escape. In red, light blue, or gray, Putnam caught her quarry 40 percent of the time. In dark blue, that number went up to 84 percent.

The findings are a good reminder to all animal researchers, Putnam said in a statement. "What we wear can have indirect effects on animals through changes in their behavior."

Thanks to new, high-tech materials, our favorite shoes are lighter and more comfortable than ever. Unfortunately, one thing most sneakers are not is durable. They can’t protect your feet from the rain, let alone heavy objects. Luckily, as their name implies, Indestructible Shoes has come up with a line of steel-toe boots that look and feel like regular sneakers.

Made to be incredibly strong but still lightweight, every pair of Indestructible Shoes has steel toes, skid-proof grips, and shock-absorption technology. But they don't look clunky or bulky, which makes them suitable whether you're going to work, the gym, or a family gathering.

The Hummer is Indestructible Shoes’s most well-rounded model. It features European steel toes to protect your feet, while the durable "flymesh" material wicks moisture to keep your feet feeling fresh. The insole features 3D arch support and extra padding in the heel cup. And the outsole features additional padding that distributes weight and helps your body withstand strain.

The upper is made of breathable moisture-wicking flymesh to help keep your feet dry in the rain or if you're wearing them on the water.

If you want a more breathable shoe for the peak summer months, there's the Ryder. This shoe is designed to be a stylish solution to the problem of sweaty feet, thanks to a breathable mesh that maximizes airflow and minimizes sweat and odor.

The Reason Your Dog Follows You Everywhere

Depending on your mood, a dog that follows you everywhere can be annoying or adorable. The behavior is also confusing if you're not an expert on pet behavior. So what is it about the canine companions in our lives that makes them stick by our sides at all times?

Most experts agree on a few different reasons why some dogs are clingy around their owners. One is their pack mentality. Dogs may have been domesticated thousands of years ago, but they still consider themselves to be part of a group like their wild ancestors. When there are no other dogs around, their human family becomes their pack. According to Reader's Digest, this genetic instinct is also what motivates dogs to watch you closely and seek out your physical touch.

The second reason for the behavior has to do with the bond between you and your pet. As veterinarian Dr. Rachel Barrack told the American Kennel Club, puppies as old as 6 months can imprint on their human owners like they would their own mothers. Even older dogs will bond with the humans in their lives who show them care and affection. In these cases, a dog will shadow its owner because it sees them as an object of trust and security.

The last possible explanation for why your dog follows you has more to do with your treatment of them than their natural instincts. A popular training tactic is positive reinforcement—i.e. rewarding a dog with treats, pets, and praise when they perform positive behaviors. The point is to help your dog associate good behaviors with rewards, but after a while, they may start to associate your presence with rewards as well. That means if your dog is following you, they may be looking for treats or attention.

A clingy dog may be annoying, but it usually isn't a sign of a larger problem. If anything, it means your dog sees you in a positive light. So enjoy the extra companionship, and don't be afraid to close the door behind when you need some alone time.
