Innovation: Ultimate Jukebox Is Next Step In Net Music

Find what you want and listen to it (Image: Gary Burchell/Getty)

From New Scientist:

Something exciting has just happened to online music, and it has nothing to do with Google's new music service garnering all the headlines.

If you Google search for music related terms, like an artist's name, some results now come with links to audio previews for relevant tracks. It is easy to use, but the service taps into just a few of the online music streaming sites. Lala and iLike are included but others with large libraries like Spotify and Last.fm are ignored. It also only works in the US. But more importantly, Google's service only helps people find music, and what they really want is to listen to it.

9,000-Year-Old Brew Hitting The Shelves This Summer

From Scientific American:

This summer, how would you like to lean back in your lawn chair and toss back a brew made from what may be the world’s oldest recipe for beer? Called Chateau Jiahu, this blend of rice, honey and fruit was intoxicating Chinese villagers 9,000 years ago—long before grape wine had its start in Mesopotamia.

University of Pennsylvania molecular archaeologist Patrick McGovern first described the beverage in 2005 in the Proceedings of the National Academy of Sciences based on chemical traces from pottery in the Neolithic village of Jiahu in Northern China.

20 Things You Didn't Know About... Sugar

From Discover Magazine:

We eat it, we love it, and it may have been a chemical precursor to life on Earth.

1 The average American eats 61 pounds of refined sugar each year, including 25 pounds of candy. Halloween accounts for at least two pounds of that.

2 Trick: Sugar may give you wrinkles via a process called glycation, in which excess blood sugar binds to collagen in the skin, making it less elastic.

3 Or treat: Cutting back on sugar may help your skin retain its flexibility. So actually, no treats.

Los Alamos National Laboratory conducts much of the nation's nuclear security research, and a new study has found that the plutonium facility may not be equipped to safely ride out an earthquake.

The lab, situated about 56 kilometers outside of Santa Fe, N.M., has long been known to be on a fault line, and builders have installed substantial fire safety measures. But recent planning for a new structure revealed that the fault could move much more than previously assumed, revealing a crack in the lab's safety plans, the Los Angeles Times reported.

From The Telegraph:

Britain's tea lovers are raising a cup to scientists after they worked out how to stop a teapot dribbling.

A team of fluid dynamics experts have after exhaustive research concluded that the problem is a phenomenon known as the "hydro-capillary effect".

And the answer is to deploy a "superhydrophobic" material. In other words you could put butter down the spout.

They have deduced that at low pouring speeds tea starts to stick to the inside of the spout, causing the flow to momentarily stop and then start again – in other words to dribble.

Testing Cheap Wind Power

From Technology Review:

A continuously variable transmission could lead to cheaper wind power--if it is rugged enough.

Federal stimulus funds awarded to a wind-energy research consortium led by Illinois Institute of Technology will accelerate testing of small wind turbines that could point the way towards more efficient utility-scale machines. The eight-kilowatt turbines, the product of Cedar Park, TX-based Viryd Technologies, use a mechanical approach--continuously variable transmission (CVT) technology--to convert fluctuating wind speeds into the precise stream of alternating current required by power grids. If it can replace the pricey power electronics that regulate power in most turbines today, the same technology could cut the cost of wind-power generation at any scale.

Using seven different filters, Hubble captured the Jewel Box cluster in far ultraviolet to near-infrared light. The different colors of the stars — from pale blue to bright ruby red — result from their differing intensities at various ultraviolet wavelengths.

5 Frightening (But True) Space Stories

The explosion was detected on April 23 by NASA's Swift satellite, and scientists soon realized that it was more than 13 billion light-years from Earth. It represents an event that occurred 630 million years after the Big Bang, when the Universe was only four percent of its current age of 13.7 billion years.

Astronomical Artifact: Most Distant Object Yet Detected Carries Clues From Early Universe

A false-color image from the Gemini North Telescope in Hawaii shows the afterglow of GRB 090423 [circled], the most distant astronomical event yet observed. Gemini Observatory/NSF/AURA, D. Fox and A. Cucchiara (Penn State University) and E. Berger (Harvard University)

From Scientific American:

A stellar explosion spotted in April took place 13 billion years ago.

A violent explosion picked up by a NASA satellite earlier this year is the oldest object ever seen by astronomers, its light having been emitted some 13 billion years ago. At that time the universe was roughly 5 percent of its present age and the big bang was a fairly recent occurrence, having taken place just 600 million years earlier.

NASA's Swift Gamma-Ray Burst spacecraft spotted the flash signaling a massive stellar explosion on April 23. The explosion was officially designated GRB 090423, after its type (a gamma-ray burst) and date of detection; the space agency quickly announced it as the new record holder for cosmic distance. Now, two papers in the October 29 Nature present detailed analyses of the burst and afterglow, confirming the initial distance assessments and providing a few clues as to conditions in the early universe.
