| Researchers estimate a cost for universal access to energy Posted: 02 May 2013 07:58 PM PDT Universal access to modern energy could be achieved with an investment of between 65 and 86 billion US dollars a year up until 2030, new research has shown. The proposed investments are higher than previous estimates but equate to just 3-4 per cent of current investments in the global energy system. |
| Dual-color lasers could lead to cheap and efficient LED lighting Posted: 02 May 2013 07:58 PM PDT A new semiconductor device capable of emitting two distinct colors has been created by a group of researchers in the US, potentially opening up the possibility of using light emitting diodes (LEDs) universally for cheap and efficient lighting. |
| New dark matter detector begins its search Posted: 02 May 2013 03:53 PM PDT Scientists heard their first pops this week in an experiment that searches for signs of dark matter in the form of tiny bubbles. Scientists will need further analysis to discern whether dark matter caused any of the COUPP-60 experiment's first bubbles at the SNOLAB underground science laboratory. |
| Robotic insects make first controlled flight Posted: 02 May 2013 11:26 AM PDT In the very early hours of the morning, in a Harvard robotics laboratory last summer, an insect took flight. Half the size of a paperclip, weighing less than a tenth of a gram, it leaped a few inches, hovered for a moment on fragile, flapping wings, and then sped along a preset route through the air. This demonstration of the first controlled flight of an insect-sized robot is the culmination of more than a decade's work. |
| How graphene and friends could harness the Sun's energy hitting walls Posted: 02 May 2013 11:25 AM PDT Combining wonder material graphene with other stunning one-atom thick materials could create the next generation of solar cells and optoelectronic devices, scientists have revealed. Researchers have shown how building multi-layered heterostructures in a three-dimensional stack can produce an exciting physical phenomenon exploring new electronic devices. The breakthrough, published in Science, could lead to electric energy that runs entire buildings generated by sunlight absorbed by its exposed walls; the energy can be used at will to change the transparency and reflectivity of fixtures and windows depending on environmental conditions, such as temperature and brightness. |
| 3-D simulation shows how form of complex organs evolves by natural selection Posted: 02 May 2013 07:45 AM PDT Researchers have developed the first three-dimensional simulation of the evolution of morphology by integrating the mechanisms of genetic regulation that take place during embryo development. The study highlights the real complexity of the genetic interactions that lead to adult organisms' phenotypes (physical forms), helps to explain how natural selection influences body form and leads towards much more realistic virtual experiments on evolution. |
| An anarchic region of star formation Posted: 02 May 2013 05:22 AM PDT The Danish 1.54-meter telescope located at the European Southern Observatory's La Silla Observatory in Chile has captured a striking image of NGC 6559, an object that showcases the anarchy that reigns when stars form inside an interstellar cloud. |
