Three U.S. scientists have figured out how flying animals make a turn, and then continue straight on a new course.

It's remarkably easy, said lead researcher Tyson L. Hedrick of the biology department of the University of North Carolina. It's even easier than a person swivelling in a desk chair, he said.

That manoeuvre takes three steps: Push off with one foot, roll through the turn, then stop with the other foot.

But for a bat, bird or bee, turning is easier. Start the turn, and then flap normally to continue on the new course.

"We didn't expect things to fall out this neatly," he said.

Researchers found the process is the same for all flying animals from fruit flies to large birds.

Hedrick and two colleagues showed that flapping fliers have a passive mechanism called flapping counter-torque (FCT) which dampens the effects of the turn.

Their FCT model "also shows how animals may simultaneously specialize in both manoeuvrability and stability [at the cost of efficiency]," and links the animal's structure, wing kinematics, manoeuvrability, and flight dynamics, the abstract of their article said. It was published in the journal Science on Friday.

The research could aid the study of robotic flying machines, said Bret W. Tobalske of the University of Montana.

But there are still some major barriers.

Turning is one of the three motions in flying. It's called yaw in aviation, but there are still the up-and-down — pitch — and the roll, the tilt to left or right.

"We picked basically the simplest turn you can imagine to make comparison," Hedrick said.

Hedrick worked with Bo Cheng and Xinyan Deng, both with the mechanical engineering department of the University of Delaware.

it took them that long to figure that out.

You just know that research was funded to the tits by the USAF....

I have to assume the article dumbs down their actual findings. Otherwise :facepalm:

And it only cost millions of taxpayer dollars. Next will be research on tootsie pop licks. :smelly:

LOS ANGELES - A surprising new study released Monday by UCLA's Institute For Child Development revealed that human babies, long thought by psychologists to be highly inquisitive and adaptable, are actually extraordinarily stupid.

The study, an 18-month battery of intelligence tests administered to over 3,500 babies, concluded categorically that babies are "so stupid, it's not even funny."

According to Institute president Molly Bentley, in an effort to determine infant survival instincts when attacked, the babies were prodded in an aggressive manner with a broken broom handle. Over 90 percent of them, when poked, failed to make even rudimentary attempts to defend themselves. The remaining 10 percent responded by vacating their bowels.

It is unlikely that the presence of the babies' fecal matter, however foul-smelling, would have a measurable defensive effect against an attacker in a real-world situation," Bentley said.

Another test, in which the infants were placed on a mound of dirt outdoors during a torrential downpour, produced similarly bleak results.

"The chicken, dog and even worm babies that we submitted to the test as a control group all had enough sense to come in from the rain or, at least, seek shelter under a leafy clump of vegetation or outcropping of rock," test supervisor Thomas Howell said. "The human babies, on the other hand, could not grasp even this incredibly basic concept, instead merely lying on the ground and making gurgling noises."

According to Howell, almost 60 percent of the infants tested in this manner eventually drowned.

Some of the babies tested were actually so stupid that they choked to death on pieces of Micronaut space toys. Others, unable to use such primitive instruments as can openers and spoons due to insufficient motor skills, simply starved to death, despite being surrounded by cabinets full of nutritious, life-giving Gerber-brand baby-food products.

Babies, the study concluded, are also too stupid to do the following: avoid getting their heads trapped in automatic car windows; use ice to alleviate the pain of burn injuries resulting from touching an open flame; master the skills required for scuba diving; and use a safety ladder to reach a window to escape from a room filled with cyanide gas.

"As a mother of four, I find these results very disheartening," Bentley told reporters. "I can honestly say that the effort I have expended trying to raise my children into intelligent beings may have been entirely wasted, a fool's dream, if you will."

Study results also prompted a strong reaction from President Clinton. "All of us, on some primitive, mammalian level, feel a great sense of pride in our offspring," Clinton said. "It is now clear, however, that these feelings are unfounded. Given the overwhelming evidence of their profound stupidity, we have no choice but to replace our existing infant population with artificially incubated simu-drones, with the eventual goal of phasing out the shamefully stupid human baby forever." - The Onion

Or dog survives without assistance from humans?

Its amazing that it survived the 5 miles of swimming in the water, but the rest of it, its a dog, they'll eat anything they are friendly wild animals

actually they aren't wild. that term means something, and the thing it means is the opposite of "domesticated" which that dog is.
