Ice Age Beasts In Europe: Migration Of The Woolly Rhinoceros Earlier Than Assumed:
The newly described skull of the oldest woolly rhinoceros in Europe shows that these giant creatures - with two impressively large horns on the bridge of their noses - once roamed across central Germany. The large shaggy mammals grazed at the foot of the Kyffhäuser range, whose unforested, rocky slopes loomed out of the broad, bleak plains of northern Thuringia 460,000 years ago. The climate at this time was icy cold and far drier than today.
Evolution's New Wrinkle: Proteins With 'Cruise Control' Act Like Adaptive Machines:
A team of Princeton University scientists has discovered that chains of proteins found in most living organisms act like adaptive machines, possessing the ability to control their own evolution.
Joyful Music May Promote Heart Health:
Listening to your favorite music may be good for your cardiovascular system. Researchers at the University of Maryland School of Medicine in Baltimore have shown for the first time that the emotions aroused by joyful music have a healthy effect on blood vessel function.
Strong Education Blunts Effects Of Alzheimer's Disease, Study Suggests:
A test that reveals brain changes believed to be at the heart of Alzheimer's disease has bolstered the theory that education can delay the onset of the dementia and cognitive decline that are characteristic of the disorder.
Round Gobies: Alien Fish In Swedish Waters:
A round goby (Neogobius melanostomus) was caught in late July off the Swedish coast near Karlskrona. This is the first find of its kind in Sweden. The species, which originates from the Black Sea and probably spread to the Baltic via ballast water, has been found in the Gulf of Gdansk since 1990, in the southern Baltic.
Loggerhead Turtle Release To Provide Vital Information To Scientific Community:
On Thursday, November 6, 2008, Dr. Kirt Rusenko, Marine Conservationist, and staff from Gumbo Limbo Nature Center in Boca Raton will release two juvenile loggerhead sea turtles raised in captivity into the Indian River Lagoon near Sebastian Inlet.
Fiddler Crabs Reveal Honesty Is Not Always The Best Policy:
Dishonesty may be more widespread in the animal kingdom than previously thought. A team of Australian ecologists has discovered that some male fiddler crabs "lie" about their fighting ability by growing claws that look strong and powerful but are in fact weak and puny. Published this week in the British Ecological Society's journal Functional Ecology, the study is the first direct evidence that crabs "bluff" about their fighting ability.
Deep Heat Solution To 500-million Year Fossil Mystery:
The 500 million year-old fossils of the Burgess Shale in Canada, discovered over a century ago, still provide one of the most remarkable insights into the dawn of animal life. The beautiful silvery fossils show the true nature of the life of that time, just after the "Cambrian explosion" of animal life.
Yet, their existence is a paradox: the fossils have been buried deep in the Earth's crust and heated to over 300°C (~600 °F), before being thrust up by tectonic forces to form a mountainous ridge in the Rockies. Usually such extreme conditions are thought to destroy fossils. But, in the Burgess Shale the most exquisite detail of soft tissues has been preserved.
