| Some giant planets in other systems most likely to be alone Posted: 07 May 2012 06:01 PM PDT "Hot Jupiter-type" planets are most likely to be alone in their systems, according to new research.  |
| Looking for Earths by looking for Jupiters Posted: 07 May 2012 01:55 PM PDT In the search for Earth-like planets, it is helpful to look for clues and patterns that can help scientist narrow down the types of systems where potentially habitable planets are likely to be discovered. New research narrows down the search for Earth-like planets near Jupiter-like planets. Their work indicates that the early post-formation movements of hot-Jupiter planets probably disrupt the formation of Earth-like planets.  |
| Best websites balance self-expression and functionality Posted: 07 May 2012 01:46 PM PDT Giving people the freedom -- but not too much freedom -- to express themselves may help designers build more interactive web portals and online communities, according to researchers.  |
| Screening for breast cancer without X-rays: Lasers and sound merge in promising diagnostic technique Posted: 07 May 2012 11:13 AM PDT In the first phase of clinical testing of a new imaging device, researchers in the Netherlands used photoacoustics rather than ionizing radiation to detect and visualize breast tumors. The team's preliminary results, which were conducted on 12 patients with diagnosed malignancies, have just been published.  |
| One supernova type, two different sources Posted: 07 May 2012 11:12 AM PDT The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. They're bright enough to see across large distances, and similar enough to act as a "standard candle" - an object of known luminosity. However, an embarrassing fact is that astronomers still don't know what star systems make Type Ia supernovae.  |
| Home computer data usage: Bandwidth caps create user uncertainty, risky decisions Posted: 07 May 2012 08:37 AM PDT A new study shows that capped broadband pricing triggers uneasy user experiences that could be mitigated by better tools to monitor data usage through their home networks.  |
| Materials science: Perfecting the defect Posted: 07 May 2012 07:09 AM PDT Simulations of defects inside copper point the way to making stronger metals. Results show that there are many different deformation mechanisms occurring in nano-structured materials like nanotwinned copper. Understanding each of them will allow scientists to tune material properties.  |
| Hubble sees the eye of the storm in galaxy cluster Posted: 07 May 2012 06:31 AM PDT A new image from the NASA/ESA Hubble Space Telescope could seem like a quiet patch of sky at first glance. But zooming into the central part of a galaxy cluster -- one of the largest structures of the Universe -- is rather like looking at the eye of the storm.  |
| Posted: 06 May 2012 01:01 PM PDT Researchers have developed a way to automate the process of finding and recording information from neurons in the living brain. The researchers have shown that a robotic arm guided by a cell-detecting computer algorithm can identify and record from neurons in the living mouse brain with better accuracy and speed than a human experimenter.  |
