(PhysOrg.com) -- Current methods of searching audiovisual content can be a hit-and-miss affair. Manually tagging online media content is time consuming, and costly. But new 'query by example' methods, built on peer-to-peer (P2P) architectures, could provide the way forward for such data-intensive content searches, say European researchers. http://www.physorg.com/news177780052.html Technology Wed, 18 Nov 2009 15:30:01 EST news177780052 (PhysOrg.com) -- Ionic liquids are molecular solutions that have a wide range of potential applications, including next-generation solar cells, hydrogen fuel cells and lithium batteries. http://www.physorg.com/news177346176.html Chemistry Fri, 13 Nov 2009 15:10:01 EST news177346176 Samsung Electronics announced today that it has developed the world's thinnest multi-die package, one that measures a mere 0.6mm in height. Designed initially for 32 gigabyte (GB) densities, the new memory package is just half the thickness of a conventional memory package of eight stacked chips (or dies). The advanced packaging technology delivers a 40 percent thinner and lighter memory solution for high-density multimedia handsets and mobile devices. http://www.physorg.com/news176651546.html Technology Thu, 05 Nov 2009 13:53:06 EST news176651546 (AP) -- The EU's top antitrust official on Wednesday described a deal among Apple Inc.'s iTunes, music companies, distributors and online licensing groups as a "great breakthrough" that would roll out more Internet music sales across Europe. http://www.physorg.com/news175339635.html Technology Wed, 21 Oct 2009 10:40:02 EST news175339635 Direct communication between Earth and Mars can be strongly disturbed and even blocked by the Sun for weeks at a time, cutting off any future human mission to the Red Planet.

However, it isn`t that simple for researchers who need to measure temperatures in microfluidic systems -tiny, channel-lined devices used in medical diagnostics, DNA forensics and `lab-on-a-chip` chemical analyzers -as their current `thermometer` can only be precisely calibrated for one reference temperature. Now, researchers at the National Institute of Standards and Technology have proposed a mathematical solution that enables researchers to calibrate the `thermometer` for microfluidic systems so that all temperatures are covered. http://www.physorg.com/news171650163.html Chemistry Tue, 08 Sep 2009 18:20:01 EST news171650163 (PhysOrg.com) -- University of Leicester researchers have combined crime research and space-age technology in ways that could lead to the quick detection of counterfeit pharmaceuticals in a black market currently worth an estimated $40billion per year. http://www.physorg.com/news171610839.html Chemistry Tue, 08 Sep 2009 06:41:38 EST news171610839 (PhysOrg.com) -- In spite of rising energy prices, many car drivers in large cities still ride alone.
