Bird Penis Study Pinpoints Protein That Stops Genitals From Growing

How did the chicken lose its penis? By killing off the growing appendage in the egg.

That’s the finding of a new study, which reveals how most birds evolved to lose their external genitalia. Turns out, a particular protein released during the development of chickens, quail and most other birds nips penis development in the bud, according to the new research, published today (June 6) in the journal Current Biology.

The findings have implications for genital development in general, which is important because birth defects in the external genitalia are among the most common congenital defects in humans, said study researcher Martin Cohn, a developmental biologist at the Howard Hughes Medical Institute and the University of Florida.

Knot Physics Experiment Uses Water To Create Amazing ‘Knotted Vortex’ Loop (VIDEO)

FROM

.

After a century of studying their tangled mathematics, physicists can tie almost anything into knots, including their own shoelaces and invisible underwater whirlpools. At least, they can now thanks to a little help from a 3D printer and some inspiration from the animal kingdom.

Physicists had long believed that a vortex could be twisted into a knot, even though they’d never seen one in nature or the even in the lab. Determined to finally create a knotted vortex loop of their very own, physicists at the University of Chicago designed a wing that resembles a delicately twisted ribbon and brought it to life using a 3D printer.

Birdsong Stirs Birds’ ‘Emotions’ Much As Music Affects Humans, Brain Imaging Study Suggests

FROM

.

Birds can sing. They can dance. And they may even experience an emotional response to music similar to humans.

A new study from Emory University in Atlanta found that when birds hear birdsong, their brains show activity similar to that seen in humans when they listen to music.

“We found that the same neural reward system is activated in female birds in the breeding state that are listening to male birdsong, and in people listening to music that they like,” Sarah Earp, an Emory undergraduate who co-authored the study with neuroscientist Dr. Donna Maney, said in a written statement.

Dinosaurs’ Long Necks Made Possible By Hollow Bones, Sauropod Fossils Suggest

FROM

.

How did the largest of all dinosaurs evolve necks longer than any other creature that has ever lived? One secret: mostly hollow neck bones, researchers say.

The largest creatures to ever walk the Earth were the long-necked, long-tailed dinosaurs known as the sauropods. These vegetarians had by far the longest necks of any known animal. The dinosaurs’ necks reached up to 50 feet (15 meters) in length, six times longer than that of the current world-record holder, the giraffe, and at least five times longer than those of any other animal that has lived on land.

Barnacles Use ‘Spermcasting’ To Overcome Penis Length, New Study Suggests

FROM

Click link below picture

Even Charles Darwin marveled at the length of the barnacle’s penis. In some species, it’s up to eight times the body length. Not all barnacles are so well-endowed, however, raising the question of how animals that can’t reach their neighbors get it on. Now, new research suggests that at least one short-penised barnacle, the Pacific gooseneck barnacle, oozes sperm directly into the water for mates to capture, an approach that researchers previously considered too haphazard for the sedentary crustaceans.

.

Its penis may be shorter than other barnacles, but this one still gets around.

Why We Sneeze, and Other Fun Facts About Sneezing

Click link below picture

Did you know that the particles in a sneeze travel at 100 miles per hour? Find out more fun facts about sneezing.

Why do we sneeze? The long-standing answer has been that sneezing is a reflex. When irritants — such as germs, dust, pollen, animal dander, or pollutants, just to name just a few — infiltrate the nose lining, the brain sends out a signal to get rid of it. That triggers a deep breath, which gets held in the lungs. As a result, the chest muscles tighten and pressure builds. The tongue pushes against the roof of the mouth, forcing breath to come out fast through the nose — Achoo!

Buck, Horrifically Injured ‘Dog Who Wouldn’t Die,’ Recovers Thanks To Facebook Campaign (PHOTOS, VIDEO)

FROM

.

Thanks to the residents of a Texas city and a Facebook campaign that has gone viral, an abused dog who was was left for dead in a garbage bag has been given a new chance at life.

The pooch, who has since been named “Buck,” was reportedly found on Jan. 5, after a local resident of Conroe, Tex., noticed that a garbage bag left on the side of the road and “tied to a t-post of a fence” was moving. He tore the bag open and was shocked to find the 3-year-old mixed breed, covered in blood and weakened by the cold, inside.
