There is an orange tabby cat napping in this photo. Can you spot it?
Redditor jmankruse posted the above photo of his cat Lloyd taking a snooze on some logs a month ago, and the good folks at Sploid shared it today. As a cat lover who prides herself on finding the cat in every single situation (it me!), I’m embarrassed to admit that it took me a very long time to locate Lloyd.
Why is it so hard to spot Lloyd? As mental_floss’s own Kate Horowitz explained last year, it’s because even though he’s a cat, Lloyd looks too similar to the logs around him for our eyes to easily pick him out:
"Human vision is very interested in changes and difference. When something new or unusual appears in your field of vision, your brain says, 'Ooh! Ooh! Different! Look at that!' But we’re really only good at noticing the big, significant differences. Our eyes take in information at an astounding rate, and we can't possibly pay attention to all of it."
Keep looking, and you’ll eventually find Lloyd (who, it must be said, is pretty cute). Or you can just look at the solution here. And when you’re done, try to find the iPhone on this carpet.
Octopuses can do some pretty amazing things with their skin, like “see” light, resist the pull of their own sticky suction cups, and blend in seamlessly with their surroundings. That last part now has the U.S. Army interested, as Co.Design reports. The military branch’s research office has funded the development a new type of morphing material that works like an octopus’s dynamic skin.
The skin of an octopus is covered in small, muscular bumps called papillae that allow them to change textures in a fraction of a second. Using this mechanism, octopuses can mimic coral, rocks, and even other animals. The new government-funded research—conducted by scientists at Cornell University—produced a device that works using a similar principle.
“Technologies that use stretchable materials are increasingly important, yet we are unable to control how they stretch with much more sophistication than inflating balloons,” the scientists write in their study, recently published in the journal Science. “Nature, however, demonstrates remarkable control of stretchable surfaces.”
The membrane of the stretchy, silicone material lays flat most of the time, but when it’s inflated with air, it can morph to form almost any 3D shape. So far, the technology has been used to imitate rocks and plants.
You can see the synthetic skin transform from a two-dimensional pad to 3D models of objects in the video below:
It’s easy to see how this feature could be used in military gear. A soldier’s suit made from material like this could theoretically provide custom camouflage for any environment in an instant. Like a lot of military technology, it could also be useful in civilian life down the road. Co.Design writer Jesus Diaz brings up examples like buttons that appear on a car's dashboard only when you need them, or a mixing bowl that rises from the surface of the kitchen counter while you're cooking.
Even if we can mimic the camouflage capabilities of cephalopods, though, other impressive superpowers, like controlling thousands of powerful suction cups or squeezing through spaces the size of a cherry tomato, are still the sole domain of the octopus. For now.
According to the ASPCA, 3.3 million dogs enter shelters each year in the United States. Although that number has gone down since 2011 (from 3.9 million) there are still millions of dogs waiting in shelters for a forever home. October is Adopt a Shelter Dog Month; here are 25 benefits of adopting a shelter dog.
