using rat neurons to control machine. great. as if the robot dog wasn’t disturbing enough. i am sooooo tired
Regarding plastics leaching chemicals in The Science Word 08_12_02 — this is old news. If the University of Alberta lab mentioned in the video only just discovered this problem in 2008, they have not been paying attention. Estrogen mimicking chemicals were found leaching out of plastic as far back as 1988. See Ana Soto and Carlos Sonnenschein, Tufts Medical School, Boston, 1987 through 1989, published 1991. Similarly, David Feldman and a team at Stanford ran down bisphenol-A in lab flasks and published in 1993.
Query:
Google misled me to the extent of my supposing I might find out here what sort of brains avian species might have.
Does anyone know where I can get an authoritative account? One expert source, a human brain scientist, suggested that birds lack a cerebrum; another suggested otherwise. I need more info lest I appear to be a birdbrain myself in a philosophical manuscript I’m writing on human “personal” identity.
Dennis –
Have you seen this NOVA webpage? http://www.pbs.org/wgbh/nova/sciencenow/3214/03-brain.html
A lot of Erich Jarvis’ work deals with the classification of bird brain structures to specific functions; mainly with regard to the song system, but generally as well.
Don’t listen to the human brain scientists when it comes to bird research. Most of them are quite behind on the recent avian neuro-anatomical reclassifications that have taken place, and would probably find themselves very surprised at the results.
Thanks for the info! (It didn’t dawn on me that there might be classificatory issues of the magnitude Jarvis’ work suggests.

Thank you
Love the site, I have to really catch up. Great Interviews, thanks for posting them.
Thorium can solve many Nuclear concerns.
Thorium is the most energy-dense substance on Earth, and enough exists to power civilization for millennia.

Earth’s two moons? It’s not lunacy, but new theory
By SETH BORENSTEIN, AP
Wed Aug 3, 7:11 PM EDT
WASHINGTON — In a spectacle that might have beguiled poets, lovers and songwriters if only they had been around to see it, Earth once had two moons, astronomers now think. But the smaller one smashed into the other in what is being called the “big splat.”
The result: Our planet was left with a single bulked-up and ever-so-slightly lopsided moon.
The astronomers came up with the scenario to explain why the moon’s far side is so much more hilly than the one that is always facing Earth.
The theory, outlined Wednesday in the journal Nature, comes complete with computer model runs showing how it might have happened and an illustration that looks like the bigger moon getting a pie in the face.
Outside experts said the idea makes sense, but they aren’t completely sold yet.
This all supposedly happened about 4.4 billion years ago, long before there was any life on Earth to gaze up and see the strange sight of dual moons. The moons themselves were young, formed about 100 million years earlier when a giant planet smashed into Earth. They both orbited Earth and sort of rose in the sky together, the smaller one trailing a few steps behind like a little sister in tow.
The smaller one was a planetary lightweight. The other was three times wider and 25 times heavier, its gravity so strong that the smaller one just couldn’t resist, even though it was parked a good bit away.
“They’re destined to collide. There’s no way out. … This big splat is a low-velocity collision,” said study co-author Erik Asphaug, a planetary scientist at the University of California, Santa Cruz.
What Asphaug calls a slow crash is relative: It happened at more than 5,000 mph, but that’s about as slow as possible when you are talking planetary smashups. It’s slow enough that the rocks didn’t melt.
And because the smaller moon was more than 600 miles wide, the crash took a while to finish even at 5,000 mph. Asphaug likened the smaller moon to a rifle bullet and said, “People would be bored looking at it because it’s taking 10 minutes just for the bullet to bury itself in the moon. This is an event if you were looking at, you’d need a big bag of popcorn.”
The rocks and crust from the smaller moon would have spread over and around the bigger moon without creating a crater, as a faster crash would have done.
“The physics is really surprisingly similar to a pie in the face,” Asphaug said.
And about a day later, everything was settled and the near and far sides of the moon looked different, Asphaug said.
Co-author Martin Jutzi of the University of Bern in Switzerland said the study was an attempt to explain the odd crust and mountainous terrain of the moon’s far side. Asphaug noticed it looked as if something had been added to the surface, so the duo started running
computer simulations of cosmic crashes.
Earth had always been an oddball in the solar system as the only planet with a single moon. While Venus and Mercury have no moons, Mars has two, while Saturn and Jupiter have more than 60 each. Even tiny Pluto, which was demoted to dwarf status, has four moons.
The theory was the buzz this week in Woods Hole, Mass., at a conference of scientists working on NASA’s next robotic mission to the moon, said H. Jay Melosh of Purdue University.
“We can’t find anything wrong with it,” Melosh said. “It may or may not be right.”
Planetary scientist Alan Stern, former NASA associate administrator for science, said it is a “very clever new idea,” but one that is not easily tested to learn whether it is right.
A second moon isn’t just an astronomical matter. The moon plays a big role in literature and song. And poet Todd Davis, a professor of literature at Penn State University, said this idea of two moons — one essentially swallowing the other — will capture the literary imagination.
“I’ll probably be dreaming about it and trying to work on a poem,” he said.
