Material With Negative Refractive Index Created

holy_calamity writes"The race to build a material with a negative index of refraction for visible light has been won by researchers in Germany. The advance could lead to super-lenses able to see details finer than the wavelength of visible light, or the previously predicted invisibility cloak for visible light."
From the article: "[The researcher] determined the refractive index of the material by measuring the 'phase velocity' of light as it passed through. His measurements show the structure has a negative refractive index of -0.6 for light with a wavelength of 780 nm [the far red end of the visible light spectrum]. This value drops to zero at 760 nm and 800 nm, and becomes positive at longer and shorter wavelengths."

Alcohol 'may prevent arthritis' The research did not say how much alcohol would have the same effect on humans Drinking a moderate amount of alcohol each day could protect against arthritis, a study of mice has found. In the Swedish study, mice whose water contained 10% alcohol had a lower risk of rheumatoid arthritis. The team said it was not possible to say exactly how much alcohol would have the same effect for humans.





Buying or Selling Gadgets? Try Flippid Second hand tech usually go the way of Craigslist or eBay. One is a den of cheapskates and scamsters, and the other is a den of cheapskates and thieves. What's a guy to do? Perhaps this new Flippid service is the solution. How it works: sellers list an item with a price and appropriate tags. If someone likes the price, they can buy it right away. If not, buyers can list items they want with the appropriate tags, and if a seller likes the price, they can choose to sell to the buyer. Matchmaking and Web 2.0 bliss. There are even RSS feeds for easy tracking. So far the site only has a couple handfuls of products, but may shape up to be something pretty decent if there are enough users on there. – JASON CHEN

ANYONE EVER SEEN THIS MOVIE?

Revisiting the Physics of Buckaroo Banzai

from the blast-from-the-past dept.
serutan writes"Shortly before the release of 'The Adventures of Buckaroo Banzai: Across the 8th Dimension' in 1984, physicist Carl Sneider of U.C. Berkeley wrote a surprisingly interesting essay on the physics behind the movie. Since the essay is not widely available on the web and I could only find it in plain text, I posted a more readable HTML version on my site. Among the more interesting points Sneider makes are that the oscillation overthruster is the result of decades of research instead of the usual laboratory accident, and its development corresponds surprisingly well with the evolution of particle physics from the 1930s to the 80s."





New Type of Hot Air Blimp
Posted by kdawson on Monday December 18, @02:43PM
from the still-waiting-for-the-rocket-car dept.
An anonymous reader writes to let un know about a story up on the Experimental Aircraft Association site about a new kind of blimp. From the article:
"Alberto, whose name pays homage to Brazilian aviation pioneer, Alberto Santos-Dumont, is 102 feet long with a 70-foot diameter and uses hot air rather than helium for lift. Its innovative foldable frame (much like an giant umbrella) creates structural support of its hot-air envelope, and it has a fly-by-wire vectored thrust steering system. Alberto is a hybrid; a hot-air balloon with aluminum ribs that looks more like a blimp, but with a tail propeller that gives it directional control." The home site of the blimp's developers has a timeline, photos, and a video of the blimp in flight.





New Design Principle Enables Insulation Breakthrough

December 19, 2006 7:11 AM - Tim McGee, Los Angeles

Here in the northern hemisphere it is getting cold this time of year. Naturally, it is appropriate that researchers at the University of Oregon have made a breakthrough in materials science that stops cold dead in its tracks. David C. Johnson, a professor of chemistry and member of the UO Materials Science Institute, describes why the random stacking of tungsten-diselenide planes (WSe2) creates such a good insulator.

"The reason for the extraordinarily low thermal conductivity that we've now achieved is an unusual structure which is crystalline in two directions but has a subtle rotational disorder in the direction of low-heat conduction," Johnson said.

While this new material is not a candidate for house insulation or other such large-scale applications, it does provide a new principle on which other materials could be based. This design created a material that was six times less thermally conductive then they expected, and it is 30 times less conductive then what the crystal would be in a single layer- I can't help but think about how an Abalone shell is 3,000 times stronger then the crystal alone due to a similar layer strategy. Regardless, the ability to create this kind of a material will be important in new electronic technology.

"Thermal conductivity is an important property in both conserving energy and in converting between forms of energy," Johnson said. "Obtaining low thermal conductivity in a thermoelectric material, which converts temperature gradients into electrical energy, increases efficiency."




Finding Motivation: What To Do When You Don’t Feel Like Doing Anything


Many people should come across this before: Sometimes you may find yourself not interested to do anything productive. You want to chill out and take a rest, but you already took a long break. Simply, you’re not motivated. What should you do? Chris Widener at his site Made for Success suggests number of ways to break through the phase:

  • Honestly evaluate whether or not you need a break.
  • Start small.
  • Change your routine.
  • Reward yourself.
  • Reconnect the action with pleasure rather than pain.

Change the routine sometimes work wonder. Human being is a creative creature, you will get sick on some routine work. Change the routine to fool your brain this is a whole new stuff.

First Big Partner for Zudeo: BBC Michael Arrington  Zudeo, the new “100% legal” content sharing site launched by popular BitTorrent company Azureus two weeks ago, just nailed a distribution deal with the BBC. That just took them from a theoretically cool product to a player in the online video space.Under the agreement, BBC will license a number of television shows to U.S. users, including Red Dwarf, Strange and Invasion Earth, Little Britain, Doctor Who, Fawlty Towers, Coupling, Keeping Up Appearances, League of Gentlemen and Ideal.It is a tragedy that they didn’t include the only BBC show worth watching, The Office. Of course, that show is readily available on Azureus’ BitTorent client.The benefits of Zudeo are pretty clear to publishers, who can leverage P2P networks to substantially decrease bandwidth costs and speed downloads for users.This spells trouble for Pando and Red Swoosh, which offer competing products to publishers. Zudeo probably isn’t focused on those companies, though. There is a multi-party war brewing for IPTV eyeballs between iTunes, Venice Project, Zudeo and YouTube. Watch this space.

Good documentaries on Google video 
Alf LaMont says: "I found that Google Video has full length episodes of Nova, including The Elegant Universe (A Personal Favorite), and Also full length versions of Richard Dawkins' THE GOD DELUSION. Both very powerful pro-science documentaries, and perfectly free." Link
