| Prototype device translates sign language Posted: 01 Jun 2012 10:59 AM PDT The hearing impaired may soon have an easier time communicating with those who do not understand sign language due to a new device. During the past semester, students in engineering technology and industrial design programs teamed up to develop the concept and prototype for MyVoice, a device that reads sign language and translates its motions into audible words.  |
| Venus: Planetary portrait of inner beauty Posted: 01 Jun 2012 09:30 AM PDT A Venus transit across the face of the sun is a relatively rare event -- occurring in pairs with more than a century separating each pair. There have been all of 53 transits of Venus across the sun between 2000 B.C. and the last one in 2004. On Wednesday, June 6 (Tuesday, June 5 from the Western Hemisphere), Earth gets another shot at it -- and the last for a good long while. But beyond this uniquely celestial oddity, why has Venus been an object worthy of ogling for hundreds of centuries?  |
| Saturn's geyser moon Enceladus provides a new kind of plasma laboratory Posted: 01 Jun 2012 09:21 AM PDT Recent findings from NASA's Cassini mission reveal that Saturn's geyser moon Enceladus provides a special laboratory for watching unusual behavior of plasma, or hot ionized gas. In these recent findings, some Cassini scientists think they have observed "dusty plasma," a condition theorized but not previously observed on site, near Enceladus. Data from Cassini's fields and particles instruments also show that the usual "heavy" and "light" species of charged particles in normal plasma are actually reversed near the plume spraying from the moon's south polar region.  |
| New compound could become 'cool blue' for energy efficiency in buildings Posted: 01 Jun 2012 09:06 AM PDT A new type of durable, environmentally-benign blue pigment has also been found to have unusual characteristics in reflecting heat -- it's a "cool blue" compound that could become important in new approaches to saving energy in buildings.  |
| Unique approach to materials allows temperature-stable circuits Posted: 01 Jun 2012 09:06 AM PDT Scientists have developed a unique materials approach to multilayered, ceramic-based, 3-D microelectronics circuits, such as those used in cell phones. The approach compensates for how changes due to temperature fluctuations affect something called the temperature coefficient of resonant frequency, a critical property of materials used in radio and microwave frequency applications.  |
| Quantum computers will be able to simulate particle collisions Posted: 01 Jun 2012 09:06 AM PDT Quantum computers are still years away, but a trio of theoretical physicists can already make the claim "there's an app for that." The theorists have developed a mathematical algorithm that will be used by a future quantum computer to study the inner workings of the universe in ways that are far beyond the reach of even the most powerful conventional supercomputers.  |
| Astronomers discover faintest distant galaxy Posted: 01 Jun 2012 09:06 AM PDT Astronomers have found an exceptionally distant galaxy, ranked among the top 10 most distant objects currently known in space. Light from the recently detected galaxy left the object about 800 million years after the beginning of the universe, when the universe was in its infancy. The team of astronomers identified the remote galaxy after scanning a moon-sized patch of sky with an instrument on the Magellan Telescopes at the Las Campanas Observatory in Chile.  |
| Silkmoth inspires novel explosive detector Posted: 01 Jun 2012 06:34 AM PDT Imitating the antennas of the silkmoth, Bombyx mori, researchers have designed a system for detecting explosives with unparalleled performance. Made up of a silicon microcantilever bearing nearly 500,000 aligned titanium dioxide nanotubes, this device is capable of detecting concentrations of trinitrotoluene (TNT) of around 800 ppq (1) (i.e. 800 molecules of explosive per 10^15 molecules of air), thereby improving one thousand-fold the detection limit attainable until now. This innovative concept could also be used to detect drugs, toxic agents and traces of organic pollutants.  |
| Nanotechnology breakthrough could dramatically improve medical tests Posted: 31 May 2012 01:57 PM PDT A laboratory test used to detect disease and perform biological research could be made more than 3 million times more sensitive, according to researchers who combined standard biological tools with a breakthrough in nanotechnology.  |
