NPR's Edwards Out at "Morning Edition" Louisville native Bob Edwards is out as host of National Public Radio's "Morning Edition." Edwards has hosted the show since its inception in 1-9-7-9. The radio network says the fifty-six-year-old Edwards will become a senior correspondent and contribute to a variety of broadcasts Spokeswoman Laura Gross said N-P-R's programming and news management made the change because they're trying to refresh all the network's broadcasts. Edwards says he is disappointed in the move, especially because he will not be the host when the show celebrates its silver anniversary in November. N-P-R's Steve Inskeep and Renee Montagne will serve as interim co-hosts starting in May until a permanent successor to Edwards is named. "Morning Edition" is second only to Rush Limbaugh's syndicated program as the most-listened to national radio show. N-P-R estimated Edwards has conducted 20,000 interviews during his years on the show. Edwards joined NPR in 1974, the network's third year of existence. He said he's still trying to find out more about his new assignment. fox41.com Hmmm... the change because they're trying to refresh all the network's broadcasts. and "Morning Edition" is second only to Rush Limbaugh's syndicated program as the most-listened to national radio show. lurqer

With its variety of covalent bonds, carbon is an amazing substance. Aussie boffins discover fifth form of carbon By Lucy Sherriff Boffins at Australia’s National University in Canberra have made a new - and magnetic - form of carbon which they have dubbed nanofoam. Because of its unique magnetic properties, it could have important medical applications, the team says. Speaking at the annual meeting of the American Physical Society in Montreal, Canada, John Giapintzakis of the University of Crete said he has studied the foam using an electron microscope, and had determined that it was a fifth form of carbon. He also discovered its magnetic properties. Carbon assumes this new foam-like structure when subjected to high-energy laser light. When the carbon reached around 10,000°C, it shaped itself into a lattice, or web of carbon nanotubes, according to a report on Nature. Although the foam loses its magnetism after a few hours at room temperature, even this short amount of time opens up several possible applications, according to Giapintzakis. It could make it possible to use magnetic resonance imaging to observe blood-flow, for example. Nature also suggests that it could be used to treat tumours, because it is bad at transferring heat: David Tománek of Michigan State University said that the foam could be injected into tumours and then heated. The foam would absorb the heat, and kill the tumour as the temperature rose. ® Those other four forms of carbon in full: Diamond: Hardest substance known to man, good for transmitting light, too. Particularly favoured by J'Lo, especially in its slightly pink form. Graphite: Remember pencils? The old timers used them to write stuff before computers were invented. That's carbon too. The layers in graphite slip over each other very easily, which makes it great for writing with, and a useful industrial lubricant. Bucky Balls, aka Buckminsterfullerines: These are the roundest and most symmetrical large molecule we know of. They are formed from 60 atoms of carbon bonded together in a combination of pentagons and hexagons to form a ball, just like a soccer ball. Not yet sponsored by Nike. Nanotubes: Nanotubes are very strong cylinders of carbon just one nanometre across, and up to tens of nanometres long. They might be used to strengthen polymers, and could be thought of as prototypes for a one-dimensional quantum wire. theregister.co.uk lurqer

Food for thought in evolutionary clue By Rick Weiss The evolutionary split between early humans and apes may have begun with a tiny mutation in a gene for jaw muscles -- a lucky break that allowed the skull to grow and make room for the enormous brain that would eventually become the hallmark of Homo sapiens. That's the controversial conclusion of researchers from the University of Pennsylvania, whose discovery of the mutation, announced Wednesday, has fanned the long-smoldering debate over how, exactly, modern humans evolved. The Penn team's work suggests that early primate skulls -- much like the skulls of modern gorillas and chimpanzees -- were literally muscle-bound by powerful jaw muscles and cramped by the big bony spurs that anchored them. Only when a quirk of nature produced mutants with radically smaller jaw muscles was the skull free at last to expand over the generations. The rest, as the team said, is human history. ``The going joke around the lab is that this is the `rft' mutation -- the `room for thought' mutation,'' said Hansell Stedman, who led the new work, being published in today's issue of the journal Nature. ``I love this paper. It's perfect,'' said University of Michigan paleoanthropologist Milford Wolpoff. However, ``Let's see,'' quipped the more skeptical Tim White of the University of California-Berkeley, by e-mail. ``We got big brains because little muscles . . . didn't hold the cranial bones tightly together. I may stop chewing tonight.'' But supporters and critics of the Penn proposal agreed that it was an important scientific first to have found a genetic mutation that apparently occurred just when significant physical changes were occurring in pre-humans, as documented by a number of fossil finds. mercurynews.com lurqer
