All of you have used public transportation at least once in your lives. As it stands, some of you use it every day, and are well familiar with the “platooning effect” that trams, buses and even subways seem to get into. In a nutshell, you wait and wait for a bus to come, and then three arrive at the same ... |

An international research effort, consisting of scientists from Australia and the United States, has recently beaten the world record in terms of solar-cell efficiency by 0.3 percent, and reached a total conversion rate of 43 percent. Details of the amazing work, which has the ability to completely change the way in ... |

Recent scientific studies conducted on insect flight have revealed that nature and evolution seem to favor a wing design that is not flat and inflexible, such as airplane wings. While they may get the job done transporting humans from point A to point B, they are not highly efficient in terms of performances, when co... |

The field of human health research is heavily reliant on the usual monkeys and lab rats, but other animals are used for assessing disease development or drug efficiency as well. Among them are the small fruit fly and the zebra fish. The latter was cloned several times over the last years, but through complex and expe... |

Stacking for example Rubik cubes in a storage box is a fairly easy task. They are all the same size, and can be neatly stacked on top of each other in established patterns. But when it comes to fitting as many gumballs in a single vending machine bowl, things get a little complicated. Establishing the most effective ... |

When it comes to a company assessing its own level of communication effectiveness, most managers go for the old-fashioned way, of simply and informally asking the employees what they think, most often over a cup of coffee, during breaks. But new studies say that this is not the most effective method of survey, and th... |

Australia's Commonwealth Scientific and Research Organization (CSIRO) managed to create the first smart fridge that can decide for itself how much power it needs to operate. It can also communicate with other similar devices across the network and decide the best time to use electricity, so as to avoid using it ... |

Trying to face the extremely difficult dilemma of housing a predicted 1 billion people in urban environments by 2030, Chinese authorities in Beijing and Shanghai decided a few years ago to construct the country's first green city, a project that was to house some 500,000 people, with a minimal carbon footprint o... |

Most of the light provided by the light source posted behind liquid crystal display panels never even reaches the eyes of the viewer. Light must pass through individual pixels whose brightness levels are controlled by small liquid crystals that modify their transparency according to the electric signal input. Therefo... |

Well, it doesn't really look like the car of my dreams, but it does bear some resemblance to the flying cars from 'The Jetsons', and best of all, it can run more than 100 kilometers with only one liter of fuel. Too bad it doesn't fly, though. Volkswagen's One Litre is currently the most econo... |

A new highly advanced walking robot dubbed Flame was developed recently by researcher Daan Hobbelen from TU Delft as part of his PhD research focused on revealing the way people walk. For his research Hobbelen will receive his PhD next week, on May 30. Hobbelen's findings could provide a valuable insight into ne... |

If the aircraft you're traveling in suddenly experiences some kind of damage while in mid flight, you're pretty much toast. Still, air travel is one of the safest means to get around. In theory airplanes could become even safer if they were built out of materials that regenerate themselves even while in fl... |

When talking about solar cell efficiency, even a rise of 1 percent, which to some may appear modest, is reason for researchers to celebrate. The previous solar cell conversion efficiency was averaging 21.9 percent. A new world record for solar cell efficiency has been set on Wednesday by a team of researchers from th... |

Light emitting diodes, or LEDs, are amongst the most efficient light sources ever developed. In terms of energy efficiency, light emitting diodes are capable of producing the optical output of an incandescent light bulb, by consuming one hundred times less energy. The problem is that LEDs can't compete with inca... |

LEDs have been in our lives for some time now. They are more efficient than any other lighting device before them, can produce any desired color and have a life span much longer than that of light bulbs and fluorescent tubes. However, they are still imperfect. For example, light-emitting diodes currently present on t... |

In 1879, Thomas Alva Edison invented the first electric light bulb using a carbon filament, only to receive the patent for his invention two months later. In was the greatest invention of the 19th century, but although the materials used to construct the light bulb changed slightly over the years, its design remained... |

It's about time to give a serious upgrade to the organic solar cells. Most of the solar panels built today all over the world imply a complicated manufacturing process, based on the use of scarce and extremely expensive materials, layered on top of a silicon substrate, and are able to provide a relatively effici... |

Let's see how the situation looks from above the battle field. Intel has a strong market share in its grasp thanks to a large number of products (processors, chipsets and so on) and a great marketing and advertising department. AMD on the other hand, is losing some market shares mainly because of a much more red... |
