SN 1006:

A supernova remnant about 7,000 light years from Earth.

"The original supernova explosion, caused by the destruction of a white dwarf star, was the brightest ever recorded on Earth. Elements such as iron that were previously locked up in the star were completely liberated by the supernova explosion. A combined study of its remnant, using Chandra, CTIO and VLA/GBT observations shows new evidence for the acceleration of charged particles to high energies in supernova shockwaves."

Do You Believe In Tooth Worms? Micro-images Of Strange, Worm-like Structures Uncovered Inside Dissected Molar

Do You Believe In 'Tooth Worms?' Micro-images Of Strange,
Worm-like Structures Uncovered Inside Dissected Molar

"New, micro-images of strange, worm-like structures uncovered inside a dissected molar might have been held in ancient times as proof that gnawing tooth worms were the cause of tooth decay, a theory widely believed in many cultures before modern times."

"The structures are not worms, but what they are is still in question."

Before Dinosaurs,

the First Tree-Climber Revealed

"The super-continent Pangea (or Pangaea) formed 300
million years ago and broke up about 180 million years ago."

"Long before dinosaurs dominated the Earth, ancient relatives to mammals climbed forests to feed on leaves and live high above predators that prowled the land."

"The elongated fingers, opposable "thumb," long curved claws and grasping tail of a small, huge-eyed plant-eating animal known as Suminia getmanovi demonstrate that this is the earliest known tree-climbing vertebrate, scientists now reveal."

Is There Gravity in Space?

"Astronauts and space tourists may rhapsodize about feeling weightless during spaceflight, but don't be fooled by the somewhat misleading term "zero-gravity." Every object in space still feels the gravitational pull from other objects, including space travelers who imagine themselves free of Earth's gravitational shackles."

Re-Engineering the Earth

"As the threat of global warming grows more urgent, a few scientists are considering radical--and possibly extremely dangerous--schemes for reengineering the climate by brute force. Their ideas are technologically plausible and quite cheap. So cheap, in fact, that a rich and committed environmentalist could act on them tomorrow. And that's the scariest part."

Scott Rosenberg's Wordyard & Blog Archive & A.P. goes nuclear on fair use

A.P. goes nuclear on fair use

"A.P. Cracks Down on Unpaid Use of Articles on Web." That's the headline on a New York Times article right now. But if you read the article, you see that the Associated Press's new campaign isn't only about "unpaid use of articles," it's about any use of headlines as links. In other words, it sounds like A.P. is pulling the pin on a legal Doomsday Machine for news and information on the Web -- claiming that there is no fair use right to link to articles using a brief snippet of verbiage from that article, or the original headline on the article."
