| Fuel and plastics production could be made more energy efficient and cost effective Posted: 12 Oct 2011 10:27 AM PDT Researchers have overcome a major hurdle in the quest to design a specialized type of molecular sieve that could make the production of gasoline, plastics and various chemicals more cost effective and energy efficient.  |
| Wet and mild: Researchers take the temperature of Mars' past Posted: 12 Oct 2011 10:27 AM PDT Researchers have directly determined the surface temperature of early Mars for the first time, providing evidence that's consistent with a warmer and wetter Martian past.  |
| Self-replication process holds promise for production of new materials Posted: 12 Oct 2011 10:26 AM PDT Scientists have developed artificial structures that can self-replicate, a process that has the potential to yield new types of materials.  |
| Clearing the 'cosmic fog' of the early universe: Massive stars may be responsible Posted: 12 Oct 2011 08:37 AM PDT The space between the galaxies wasn't always transparent. In the earliest times, it was an opaque, dense fog. How it cleared is an important question in astronomy. New observational evidence shows how high energy light from massive stars could have been responsible.  |
| Borrowing from brightly-colored birds: Physicists develop lasers inspired by nature Posted: 12 Oct 2011 08:35 AM PDT Researchers are studying how two types of nanoscale structures on the feathers of birds produce brilliant and distinctive colors. The researchers are hoping that by borrowing these nanoscale tricks from nature they will be able to produce new types of lasers--ones that can assemble themselves by natural processes.  |
| Erasing history? Temporal cloaks adjust light's throttle to hide an event in time Posted: 12 Oct 2011 08:35 AM PDT Researchers have demonstrated for the first time that it's possible to cloak a singular event in time, by sending a beam of light down an optical fiber and through a pair of "time lenses", creating a burst of light. They were able to create a small gap in the flow of light concealing that a burst of light ever occurred.  |
| New Saudi Arabias of solar energy: Himalaya Mountains, Andes, Antarctica Posted: 12 Oct 2011 08:35 AM PDT Mention prime geography for generation of solar energy, and people tend to think of hot deserts. But a new study concludes that some of the world's coldest landscapes -- including the Himalaya Mountains, the Andes, and even Antarctica -- could become Saudi Arabias of solar.  |
| Posted: 12 Oct 2011 05:36 AM PDT Scientists have used the European Southern Observatory's Very Large Telescope to probe the early Universe at several different times as it was becoming transparent to ultraviolet light. This brief but dramatic phase in cosmic history occurred around 13 billion years ago. By studying some of the most distant galaxies, the team has been able to establish a timeline for reionization for the first time. They have also demonstrated that this phase must have happened quicker than previously thought.  |
| Amateur skywatchers help space hazards team Posted: 12 Oct 2011 05:36 AM PDT For the first time, observations coordinated by the European Space Agency's space hazards team have found an asteroid that comes close enough to Earth to pose an impact threat. The space rock was found by amateur astronomers, highlighting the value of 'crowd-sourcing' to science and planetary defense.  |
| New mystery on Mars' forgotten plains Posted: 12 Oct 2011 05:34 AM PDT One of the supposedly best understood and least interesting landscapes on Mars is hiding something that could rewrite the planet's history. Or not. In fact, about all that is certain is that decades of assumptions regarding the wide, flat Hesperia Planum are not holding up very well under renewed scrutiny with higher-resolution, more recent spacecraft data.  |
