Picture, if you can, a prehistoric Bobby Flay — an inventive 3 million-year-old version of the Food Network star chef. He's struggling to liven up yet another salad of herbs and twigs when inspiration strikes. "We've got grass here, and sedge," he says. "Grass and sedge, that's what this dish needs!"

His pals take a tentative taste of this nouvelle cuisine. Sedges usually aren't considered gourmet fare, after all, by these human ancestors. They're tough grasslike plants that grow in marshes. But wow! Not only is this a new taste sensation, it's found in many places.

The same brain system that controls our muscles also helps us remember music, scientists say.

When we listen to a new musical phrase, it is the brain's motor system — not areas involved in hearing — that helps us remember what we've heard, researchers reported at the Society for Neuroscience meeting in New Orleans last month.

Oliver Sacks, exploring how hallucinations happen

Originally published on Thu November 8, 2012 9:58 am

In Oliver Sacks' book The Mind's Eye, the neurologist included an interesting footnote in a chapter about losing vision in one eye because of cancer that said: "In the '60s, during a period of experimenting with large doses of amphetamines, I experienced a different sort of vivid mental imagery."

He expands on this footnote in his new book, Hallucinations, where he writes about various types of hallucinations — visions triggered by grief, brain injury, migraines, medications and neurological disorders.

Sunflowers seen flying through empty desert – Why?

Originally published on Fri November 2, 2012 9:47 am

I've been hearing strange wind stories all my life. The best ones are both wildly improbable but still true, like how the Empire State Building gets hit by wafts of barley flying in on jet streams from Iowa, or how tons of sand from the Saharan desert rain down every year onto Brazilian rainforests. You never know what the wind will bring. The wind decides.

Scientists say an Asian elephant at a South Korean zoo can imitate human speech, saying five Korean words that are readily understood by people who speak the language.

The male elephant, named Koshik, invented an unusual method of sound production that involves putting his trunk in his mouth and manipulating his vocal tract.

"This is not the kind of sound that Asian elephants normally make, and it's a dead-on match of the speech of his trainers," says Tecumseh Fitch of the University of Vienna in Austria.

Sexy dino, show me your feathers - if that's why you have 'em

Originally published on Fri October 26, 2012 5:43 pm

Some of the weirdest animal behavior is about romance. That's especially true with birds — they croon or dance or display brilliant feathers to seduce the reluctant.

This sort of sexual display apparently has a long pedigree: There's now new evidence that some dinosaurs may have used the same come-on.

The source is a kind of dinosaur that was built like a 400-pound ostrich. It lived about 75 million years ago and is called ornithomimus, meaning "bird mimic."

"Frankenstorm" may be drawing the attention of meteorologists here on Earth.

But NASA scientists using the Cassini spacecraft have witnessed a rare massive storm on Saturn that was so violent it sent the temperature in the planet's stratosphere soaring to 150 degrees Fahrenheit above normal.
