Squeaking Cold!

When you walk over snow, it makes a crunching or squeaking sound, and so does frost. You might notice that when you walk on it during the daytime, it makes a lower pitched crunch than it does at night, when it is colder. The colder the temperature, the higher pitched the noise is, until it becomes a nasty squeak instead of a crunch!

Tiny, flying dinosaur discovered!

"Scientists believe they have found evidence of a tiny pterodactyl in China.
The toothless flying reptile has been studied at Brazil's national museum, where it was found to have a wing span of just 250 millimetres (9.8 inches) and unexpectedly-curved toes." This excerpt was taken from an ITN news article. Read the full article at: http://news.uk.msn.com/Article.aspx?cp-documentid=7513383

The fossilised remains were actually found by university students,
"We have this really amazing creature, sparrow sized, which lived essentially in the trees, showing us a very new, very interesting side of the evolutionary history of those animals," said Alexander W. A. Kellner of the National Museum of the Federal University of Rio de Janeiro, Brazil." began the article in Yahoo's News on the Net at:

"Other tiny pterosaurs discovered before have turned out to be hatchlings. But Nemicolopterus bears the hallmarks of a young adult, rather than an undeveloped juvenile."
