An international team of scientists has developed an organic solar cell that achieves 6.5% efficiency. While this figure is notably less than today's non-organic solutions (which reach efficiencies in excess of 40%), the teams' research has finally blasted past the 5% barrier for this type of solar cells.
Pittsburgh (PA) – Graduate students at Carnegie Mellon University have developed two tools that leverage the vast image resources available on the Internet. Their tools allow users to quickly and easily create custom, professional looking images, and with little technical know how. The application has grown out of scientific research designed to analyze qualities found in images for the purposes of tagging them with meta data.
The National Science Foundation (NSF) will soon begin allowing the San Diego Supercomputing Center (SDSC) to immediately allocate its resources in the event of an emergency. If, for example, an earthquake or other disaster takes place, these emergency jobs will be kicked off right away, providing researchers (and the public) with a fast, clear view of the event's impact.
Chicago (IL) – Taser goes new ways with a non-lethal bullet equipped with a microprocessor and battery that deliver an electrical charge via electrodes to incapacitate criminals.

The Chinese government has a long standing policy of censoring its Internet population. Decisions to remove content from search engines by companies like Google, for example, have been front page news. Still, those imposed limitations have not stopped scientists there from creating new technologies, which are designed to provide the foundation for more accurate searches.
Boeing today showcased the first assembled 787 Dreamliner jet in an unveiling attended by about 15,000 people. >> In Pictures: Boeing 787 Dreamliner
Although broadband penetration among minorities has risen significantly in the past two years, it still can't catch up to the growth in other demographics.
Over 417 million songs were purchased online in the first half of 2007, nearly double what was seen during the same time last year.
NASA has purchased a Russian-made toilet system for $19 million dollars.
The cooling needs of tomorrow's semiconductors, those which keep pace with Moore's Law, will grow to extremes. There are costly new materials solutions which indicate Moore's Law will continue for the foreseeable future. But what if we had the ability to channel heat wherever we wanted it to go via electrically controlled transistors?
Boeing will be rolling out its upcoming 787 ‘Dreamliner’ plane this Sunday in a special non-flying debut.
An iron oxide water-based solution has been discovered which changes color under varying magnetic field strengths. The solution works at extremely small scales and would be suitable for displays as well as new applications.
ESA has published stunning imagery of a star formation nearly 12.5 million light years away. Scientists were able to capture the stellar fireworks through the Hubble space telescope in the dwarf galaxy NGC 4449, which has been forming stars for thousands of millions of years.
According to ESA, the current unusual explosive and intense activity “qualifies as a starburst,” meaning that at the current rate, the gas that feeds stellar production would run out in about 1 billion years.
