Two researchers recently published a new scientific paper, arguing that intelligent lifeforms on other planets could reveal their presence to use through the lights their cities emit. While the proposal has a lot of merit, it's also worth remembering that it operates on an important assumption.
In order for the... |

Large metropolises such as New York, Tokyo and London share various traits in common, not the last of which being the fact that they are considerably warmer than their surroundings. This is largely due to the “heat island” effect, researchers say. Various factors, including city size, background ecology, ... |

The magnitude 8.8 earthquake that struck Chile on February 27 was recently established to be the fifth-strongest in recorded history, and also one of the most interesting to study, from a geological perspective. It would appear that planetary scientists have a great deal to learn from it, and also from the changes th... |

The concept of urban metabolism is not by far a new one. Scientists have proposed that similarities exist between the world's megacities and living organisms for a long time, but now reports on how human settlements function are drawing more and more parallels to the living world. The comparisons, experts say, m... |
