| Posted: 09 Jan 2015 07:10 AM PST A team of researchers has built an array of light detectors sensitive enough to register the arrival of individual light particles, or photons, and mounted them on a silicon optical chip. Such arrays are crucial components of devices that use photons to perform quantum computations. |
| Map of mysterious molecules in our galaxy sheds new light on century-old puzzle Posted: 09 Jan 2015 06:35 AM PST Astronomers have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars. |
| What can your online avatar say about your personality? Posted: 09 Jan 2015 05:47 AM PST Researchers are looking to understand the potential impressions and their limitations of those we meet in a digital context. In a new study, the researchers specifically looked at what personality traits are conveyed by a user's avatar. |
| Chitosan: Sustainable alternative for food packaging Posted: 09 Jan 2015 05:46 AM PST A material known as chitosan, made from crustacean shells, has been used to substitute petroleum by-products in food packaging. The environment is seriously affected by the use of food packaing: plastic bottles and films are present everywhere in our civilization and take between 100 and 400 years to degrade. So the quest for alternative materials to plastics produced from petroleum is an environmental priority. |
| Flexible methane production from electricity and bio-mass Posted: 09 Jan 2015 01:55 AM PST Interlinkage of the power and gas grids is planned to make electricity supply sustainable and robust in the future. Fluctuating amounts of wind and solar power, for instance, might be stored in the form of the chemical energy carrier methane. Now researchers have now proved that this is technically feasible. |
| Making synthetic materials more impervious: fewer plastic substances in food Posted: 09 Jan 2015 01:55 AM PST Synthetic materials are convenient in many respects, but they have one disadvantage: they are permeable to gases. In order to make plastic more impervious, engineers apply wafer-thin layers on surfaces. This would not only increase the shelf life of food in plastic packaging, but would also prevent the migration of substances from the plastic into the food. |
| From the lab to your digital device, quantum dots have made quantum leaps Posted: 09 Jan 2015 01:51 AM PST Quantum dots have not only found their way into tablets, computer screens, and TVs, they are also used in biological and medical imaging tools, and now researchers are exploring them for solar cell as well as brain imaging applications. |
| Smart phones, social media encourage healthy habits Posted: 06 Jan 2015 09:18 AM PST Technology may be the key to helping college-age adults make healthier choices when it comes to food and physical activity. The Youth Adults Eating and Active for Health project found that participants in the intervention groups ate more fruits and vegetables and were more physically active than those in the control groups. The 15-month study involved researchers from 14 institutions. |
