Google Indexing In Near-Realtime 79

krou writes "ReadWriteWeb is covering Google's embrace of a system that would enable any Web publisher to 'automatically submit new content to Google for indexing within seconds of that content being published.' Google's Brett Slatkin is lead developer of PuSH, or PubSubHubbub, a real-time syndication protocol based on ATOM, where 'a publisher tells the world about a Hub that it will notify every time new content is published.' Subscribers then wait for the hub to notify them of the new content. Says RWW: 'If Google can implement an Indexing by PuSH program, it would ask every website to implement the technology and declare which Hub they push to at the top of each document, just like they declare where the RSS feeds they publish can be found. Then Google would subscribe to those PuSH feeds to discover new content when it's published. PuSH wouldn't likely replace crawling, in fact a crawl would be needed to discover PuSH feeds to subscribe to, but the real-time format would be used to augment Google's existing index.' PuSH is an open protocol, and Slatkin says that 'I am being told by my engineering bosses to openly promote this open approach even to our competitors.'"

How To Make Electronic Displays With Mood Ring Ink 33

Soychemist writes "Print some thermochromic ink onto a sheet of paper, put metal heating elements on the other side, and you have a rudimentary color-changing display. Chemists in the Whitesides Group at Harvard think that the devices could be used to provide a simple readout from cheap medical tests and kits that check water for pollutants. In the past year, the same scientists have made a three-cent medical test and improvised a centrifuge with an egg beater. Their aim is to invent useful gizmos with everyday materials."

100x Denser Chips Possible With Plasmonic Nanolithography 117

Roland Piquepaille writes "According to the semiconductor industry, maskless nanolithography is a flexible nanofabrication technique which suffers from low throughput. But now, engineers at the University of California at Berkeley have developed a new approach that involves 'flying' an array of plasmonic lenses just 20 nanometers above a rotating surface, it is possible to increase throughput by several orders of magnitude. The 'flying head' they've created looks like the stylus on the arm of an old-fashioned LP turntable. With this technique, the researchers were able to create line patterns only 80 nanometers wide at speeds up to 12 meters per second. The lead researcher said that by using 'this plasmonic nanolithography, we will be able to make current microprocessors more than 10 times smaller, but far more powerful' and that 'it could lead to ultra-high density disks that can hold 10 to 100 times more data than today's disks.'"

MS Clearflow To Help Drivers Avoid Traffic Jams 243

Pioneer Woman writes "Microsoft announced plans to introduce a Web-based service for driving directions that incorporates complex software models to help users avoid traffic jams. The system is intended to reflect the complex traffic interactions that occur as traffic backs up on freeways and spills over onto city streets and will be freely available as part of the company's Live.com site for 72 cities in the US. Microsoft researchers designed algorithms that modeled traffic behavior by collecting trip data from Microsoft employees who volunteered to carry GPS units in their cars. In the end they were able to build a model for predicting traffic based on four years of data, effectively creating individual 'personalities' for over 800,000 road segments in the Seattle region. In all the system tracks about 60 million road segments in the US."

After an instrument has been assembled, extra components will be found on the bench.
