Loch Ness Monster Mystery Solved?

Posted by Staten on July 19, 2013 at 2:20 AM Comments comments (0)

Italian geologist Dr Luigi Piccardi believes something has been stirring at the bottom of the Scottish loch -- but it is not Nessie.

 

Piccardi says Loch Ness lies along the Great Glen Fault, a major fault line in the Earth's crust which is still active. Read about his new theory here and the first time he spoke of it in 2001

Nemo in trouble.

Posted by Staten on September 18, 2012 at 9:30 PM Comments comments (0)

Finding Nemo came out in 2003, and it was rereleased last week in 3D. The fish we love so much is in much more danger than the movie says.  

"We risk losing the striking fish that inspired 'Finding Nemo' forever if we don't put the brakes on global warming and ocean acidification," Shaye Wolf, the Center's climate science director, stated in a news release. "Carbon pollution harms these fish and destroys their coral reef homes. If we want these beautiful animals to survive in the wild, not just in a movie, we have to protect them under the Endangered Species Act."

 Armstrong commanded the Apollo 11 spacecraft that landed on the moon July 20, 1969, capping the most daring of the 20th century's scientific expeditions. His first words after setting foot on the surface are etched in history books and the memories of those who heard them in a live broadcast.

"That's one small step for (a) man, one giant leap for mankind," Armstrong said.

Secret to Elephant's Thundering Trumpet Calls

Posted by Staten on August 2, 2012 at 3:20 PM Comments comments (0)

By Stephanie Pappas, LiveScience Senior Writer

Elephants' deepest calls can thunder up to 6 miles (10 kilometers) away. Now, researchers have learned for the first time how the massive animals produce these sounds.

It turns out that they do it in the same way that humans talk, pushing air through their vocal cords to make them vibrate. Elephants can go much lower than humans, however, because their vocal cords are eight times longer.

"The sounds the elephants make are off the piano keyboard," said study researcher Christian Herbst, a voice scientist at the University of Vienna, Austria. In fact, at less than 20 hertz in frequency, the main components of these ultra-deep calls aren't detectable to the human ear.

Until now, researchers weren't sure how elephants produced such low sounds. In fact, it's difficult to study voice production in animals in general, Herbst told LiveScience. In humans, researchers can insert cameras through the throat into the larynx, or voicebox, while people make different sounds. Animals tend to be less cooperative on that front, Herbst said.

There are two ways to produce sound by vibrating the vocal cords (or vocal folds, as scientists call them). The first is called active muscular contraction, or AMC. With this method, the throat muscles actively contract to vibrate the vocal folds. AMC is how cats purr.

The other method of sound production is called the myoelastic-aerodynamic (MEAD) mode. The MEAD mode uses air from the lungs to vibrate the vocal folds. MEAD is how humans talk and sing.

Herbst and his colleagues were able to investigate which method elephants use when they had the opportunity to investigate the larynx of an elephant that died a natural death at the Berlin Zoo. The researchers mounted the larynx on a tube and blew humidified warm air through it to mimic breath. If this method produced vibrations that matched the low-frequency calls of living elephants, the findings would bolster the argument for MEAD-produced sounds. If the vibrations didn't match up, the sounds would have to be produced by the AMC "purring" method.

The vibrations matched. That doesn't entirely rule out AMC in elephants, the researchers report in the Aug. 3 issue of the journal Science, but it suggests that MEAD is the more likely culprit for low-frequency cries. [Video: See Elephant Vocal Vibrations]

"What is cool to me is that nature came up with a system that you can find in mammals from the very, very large — so basically we now have evidence for the largest land-based mammal — to very, very small like very tiny bats," Herbst said.

That size range brings with it an impressive range in frequency, from elephants at less than 20 hertz to bats that can squeak at more than 110,000 hertz. The human vocal cords can produce sounds ranging from about 50 hertz to 7000 hertz, with most voice sounds falling between 300 hertz and 3,400 hertz.

"It still strikes me as fantastic what we humans, particularly, can do with this system," Herbst said. Comparative anatomy of the same system in different animals can help researchers understand how voice evolved in the first place, he said.

"We see variations in the laryngeal anatomy," he said, "and usually, nature has a good reason to come up with slight variations."

NASA Rover searches for life on Mars

Posted by Staten on July 29, 2012 at 9:20 PM Comments comments (0)

The rover, also known as Curiosity, has been careening toward Mars since its launch in November. The nuclear-powered rover the size of a compact car is expected to end its 352-million-mile (567-million-km) journey on August 6 at 1:31 a.m.

A video is at the link below.
