BBC NEWS | Science & Environment | Milky Way’s sweetness throughout – A simple sugar that is an ingredient of life has been found for the first time in a relatively hospitable part of the galaxy.As molecules go, glycolaldehyde is not an impressive one, but its link to the origins of life make it significant.
It can react to form ribose, a key constituent of the nucleic acid RNA.
Robert Scoble suggests that back in 2000 (when there were few blogs) it was not unusual for a conversation to take place through the blog comments over the space of week. Now with twitter, the time shrinks dramatically. He then looks at FriendFeed and suggests that, with proper search facilities added to what is already there, the trend can be reversed and what he calls “the half life” (~20 hours in the example from 2000) will increase as older conversations can be found and referenced again.
The fund seeks to soften effects of the financial collapse, but many Asian leaders – citing bad advice from the ‘97 crisis – are wary of conditions attached to assistance.

Planning to Share versus Just Sharing at EdTechPost – This is a long post, born out of years of frustration with ineffective institutional collaborations. If you only want the highlights, here they are: grow your network by sharing, not planning to share or deciding who to share with; the tech doesn’t determine the sharing – if you want to share, you will; weave your network by sharing what you can, and they will share what they can – people won’t share [without a lot of added incentives] stuff that’s not easy or compelling for them to share. Create virtuous cycles that amplify network effects. Given the right ’set,’ simple tech is all they need to get started

GAO: urgent policy concerns for transition/new administration – Many of the urgent policy concerns identified here are critical and time sensitive and require prioritized federal action. They are issues that require a focus from the transition team and new administration because if they are not dealt with, they could have great implications for life, well being, or the confidence of citizens in government, or because they have key quickly approaching dates where a decision must be made or actions taken. Consequently, these issues are not necessarily the most important issues in the long term, but rather those that must be dealt with immediately.

Half an Hour: The Future of Online Learning: Ten Years On – Though today we stand at the cusp of this new vision, the future will see institutions and traditional forms of education receding gradually, reluctantly, to a tide of self-directing and self-motivated learners. This will be the last generation in which education is the practice of authority, and the first where it becomes, as has always been intended by educators, an act of liberty.
“Not only have individual financial institutions become less vulnerable to shocks from underlying risk factors, but also the financial system as a whole has become more resilient.”
— Alan Greenspan in 2004
This first chord that starts A Hard Day’s Night is one of the most recognizable and famous opening chords in rock & roll. It’s played by George Harrison on his 12 string Rickenbacker.
PBS NEWS HOUR Interview with Nassim Nicholas Taleb, famous economist and author of “The Black Swan” and Dr. Mandelbrot, professor of Mathematics (and originator of ‘fractal geometry’) .
Both say that the present economy more serious than the Great Depression, and the economy during the American Revolution.
This image depicts a vast canyon of dust and gas in the Orion Nebula from a 3-D computer model based on observations by NASA's Hubble Space Telescope and created by science visualization specialists at the Space Telescope Science Institute (STScI) in Baltimore, Md. A 3-D visualization of this model takes viewers on an amazing four-minute voyage through the 15-light-year-wide canyon. The model takes viewers through an exhilarating ride through the Orion Nebula, a vast star-making factory 1,500 light-years away. This virtual space journey isn't the latest video game but one of several groundbreaking astronomy visualizations created by specialists at STScI, the science operations center for NASA's Hubble Space Telescope. The cinematic space odysseys are part of the new Imax film Hubble 3D, which opens today at select IMAX theaters worldwide. The 43-minute movie chronicles the 20-year life of Hubble and includes highlights from the May 2009 servicing mission to the Earth-orbiting observatory, with footage taken by the astronauts. The giant-screen film showcases some of Hubble's breathtaking iconic pictures, such as the Eagle Nebula's "Pillars of Creation," as well as stunning views taken by the newly installed Wide Field Camera 3. While Hubble pictures of celestial objects are awe-inspiring, they are flat 2-D photographs. For this film, those 2-D images have been converted into 3-D environments, giving the audience the impression they are space travelers taking a tour of Hubble's most popular targets. Based on a Hubble image of Orion released in 2006, the visualization was a collaborative effort between science visualization specialists at STScI, including Greg Bacon, who sculpted the Orion Nebula digital model, with input from STScI astronomer Massimo Roberto; the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign; and the Spitzer Science Center at the California Institute of Technology in Pasadena. For some of the sequences, STScI imaging specialists developed new techniques for transforming the 2-D Hubble images into 3-D. STScI image processing specialists Lisa Frattare and Zolt Levay, for example, created methods of splitting a giant gaseous pillar in the Carina Nebula into multiple layers to produce a 3-D effect, giving the structure depth.
