| Venus weather not boring after all, scientists discover Posted: 27 Sep 2011 02:10 PM PDT At first glance, a weather forecaster for Venus would have either a really easy or a really boring job, depending on your point of view. The climate on Venus is widely known to be unpleasant -- at the surface, the planet roasts at more than 800 degrees Fahrenheit under a suffocating blanket of sulfuric acid clouds and a crushing atmosphere more than 90 times the pressure of Earth's. However, higher up, the weather gets more interesting, according to a new study of old data by NASA and international scientists.  |
| New 'FeTRAM' is promising computer memory technology Posted: 27 Sep 2011 12:52 PM PDT Researchers are developing a new type of computer memory that could be faster than the existing commercial memory and use far less power than flash memory devices. The technology combines silicon nanowires with a "ferroelectric" polymer.  |
| New advanced biofuel identified as an alternative to diesel fuel Posted: 27 Sep 2011 10:42 AM PDT Researchers have identified a terpene called bisabolane as a potential biofuel for replacing diesel fuel. The researchers have also engineered two strains of microbes -- a bacteria and a yeast -- that can be used in the biosynthetic production of this clean, green, renewable and domestic alternative to diesel fuel.  |
| New technique maps twin faces of smallest Janus nanoparticles Posted: 27 Sep 2011 09:49 AM PDT Chemists have developed the first method that can rapidly and accurately map the surfaces of Janus nanoparticles, tiny particles that possess two chemically distinct faces. The findings have broad potential applications ranging from drug delivery to video displays.  |
| Researchers use carbon nanotubes to make solar cells affordable, flexible Posted: 27 Sep 2011 09:49 AM PDT Researchers have found that metallic carbon nanotubes are 50 times more effective than semiconducting ones when used as transparent conductors in organic solar cells.  |
| New nanostructure-based process will streamline production of magnetic materials Posted: 27 Sep 2011 09:46 AM PDT Scientists report for the first time designing a simpler method of preparing ordered magnetic materials than ever by coupling magnetic properties to nanostructure formation at low temperatures. The process allows them to create room-temperature ferromagnetic materials that are stable for long periods more effectively and with fewer steps than more complicated existing methods.  |
| Giant star expels multiple dust shells, astronomers find Posted: 27 Sep 2011 04:26 AM PDT An international team of astronomers has discovered not less than a dozen cold dust arcs around the giant star CW Leo. The team used the sensitive PACS instrument on board the Herschel Space Observatory to detect for the first time arcs of dust far away from the star. CW Leo has expelled these shells of dust in different epochs in its life. The faintest shell we can see now was, according to the team, expelled about 16,000 years ago. In the mean time it has drifted away from the star over more than 7,000 billion kilometers.  |
