How Cats' Tongues Get Them So Clean
Cats
are known for their care of grooming themselves, but the way their
languages are able to get so clean has remained a mystery. Scientists knew that the languages of cats were covered with thorns,
and now a group of engineers found that the teensy structures are
shaped like claws and works like
velcro to clean cat layers.
The researchers said the results may help engineers design robots that can grab surfaces, and even produce brushless hairs more efficient and better ways to clean wounds. [20 strange cat and dog behaviors explained science]And licking the cat
Alexis Noel, a mechanical engineer from the Georgia Institute of Technology in Atlanta, began investigating the thorns at the ladyfingers after seeing the cat lick a thick blanket and immediately hit the tongue.
"I felt like home for a Christmas break and watching TV with family cats," said Noel. "Murphy, a 3-year-old cat, short-haired dynasty, and Tan stripes, decided to blanket on the couch off a delicious smell and decided to give it a good lick.
"When I finished laughing at this strange cat, a researcher at me began to question how soft moist tissue could stick to something so easily," said Noel Life Science Scientific. "After a few seconds of struggle, I realized that Sanh could simply be separated by pushing his tongue into a blanket instead of throwing, disengaging the blanket ties."
Using high-speed camcorders, Noel and his colleagues reported removing cat food for heavily-installed cats in a 3D style fur rug. 3D also printed a model of the cat's tongue four times larger than usual, and experimented.
"We're the first 3D imitated print of the gun," said Noel.
Scientists have observed that the spines of the language of the cats are curved and sharp. "In terms of shape and sharpness, cat claws reminds me," Noel said in a statement. , Said that the nature of the thorn hook helps to act essentially like velcro tabs while the cats slide on the skin and quickly become accustomed to its spine in the hair strands.
In addition, "When the cat's tongue hits an obstacle, pull the hooks, rotate the obstacle to continue to penetrate," Noel said in the statement. "Like heat-seeking rockets for inconvenience, the mobility hook allows the cat to better tease away the tangle." The researchers added the rotation behavior of these hooks also helps wedge molecules between them, helping them to pick up food.
Future research will explore how Noel spacing the tongue of the cat affects how ready the layer and lubricating saliva in the cat's tongue can help or hinder the setting.
"While saliva is known to break the dirt and oil, reduce the fur rug, previous research has shown that moisture actually increases the friction between the hair, which would probably pull the hair brush out of the skin - said Noel painful.
In addition, "they are also looking to learn the languages of black tigers and other large cats to understand how the thorns of the language range through the cat's family," Noel said. "However, this can be difficult to study exotic languages of animals difficult to identify and acquire."Catholic language technology
Noel said this research could help scientists design flexible robots capable of holding items. While traditional rigid robots - making them vulnerable to damage from bumps, dings, shifts and drops - soft robots made of flex plastic and rubber resist many kinds of damage and possibly grab past obstacles can be difficult to block robots.

"In the world of soft robots, researchers are still fighting for ways that soft surfaces grip materials," Noel said. ", Which can still be separated from the tangles of the skin" and added that they are flexible as they lose soft robot members - a search around ladyfingers can help overcome this challenge.
Noel said these results can also lead to better hair brushes.
"BC The first known hair brush dates back to 8000," Noel said. "Since then, the brush design has not changed, we strive to understand what makes to unravel hair hair less painful hair, how the cat's tongue can be increased to fit human hair, provide a new design to clean traditional hair.
