| More accurate Twitter analysis tools developed Posted: 27 Aug 2014 10:17 AM PDT 'Trending' topics on Twitter show the quantity of tweets associated with a specific event but trends only show the highest volume keywords and hashtags, and may not give information about the tweets themselves. Now, using data associated with the Super Bowl and World Series, researchers have developed and validated a software program that analyzes event-based tweets and measures the context of tweets rather than just the quantity. |
| New smartphone app can detect newborn jaundice in minutes Posted: 27 Aug 2014 09:25 AM PDT Engineers and physicians have developed a smartphone application that checks for jaundice in newborns and can deliver results to parents and pediatricians within minutes. Skin that turns yellow can be a sure sign that a newborn is jaundiced and isn't adequately eliminating the chemical bilirubin. But that discoloration is sometimes hard to see, and severe jaundice left untreated can harm a baby. |
| Materials Other Than Silicon for Next Generation Electronic Devices Posted: 27 Aug 2014 09:25 AM PDT Silicon has been the most successful material of the 20th century, with major global industries and even a valley named after it. But silicon may be running out of steam for high performance/low power electronics. As silicon strains against the physical limits of performance, could a material like InGaAs provide enough of an improvement over silicon that it would be worth the expense in new equipment lines and training to make the switch worthwhile? |
| Symphony of nanoplasmonic and optical resonators produces laser-like light emission Posted: 26 Aug 2014 09:11 AM PDT By combining plasmonics and optical microresonators, researchers have created a new optical amplifier (or laser) design, paving the way for power-on-a-chip applications. |
| Laser pulse turns glass into a metal: New effect could be used for ultra-fast logical switches Posted: 26 Aug 2014 07:08 AM PDT For tiny fractions of a second, quartz glass can take on metallic properties, when it is illuminated be a laser pulse. This has been shown by new calculations. The effect could be used to build logical switches which are much faster than today's microelectronics. |
| Posted: 26 Aug 2014 05:57 AM PDT Scientists have developed smart bracelets - the Smart VIB (Very Important Bracelet) that enables clients access hotel rooms without the need for a card, make payments using the PayPal system, share experiences on social networks via the numerous tactile screen, and receive completely personalized services, while at all times guaranteeing protection of information. |
| Better than CAPTCHA: Improved method to let computers know you are human Posted: 25 Aug 2014 03:55 PM PDT Researchers are investigating game-based verification that may improve computer security and reduce user frustration compared to typical "type-what-you-see" CAPTCHA tools that use static images. |
| Combining math and music to open new possibilities Posted: 25 Aug 2014 03:53 PM PDT The power of mathematics to open new possibilities in music has been demonstrated by scientists for years. Modern experiments with computer music are just the most recent example. |
