Supermassive black holes, with a mass approximately a billion times that of our Sun, have been thought to reside at the very heart of the biggest galaxies, including our own. A recent computer simulation, corroborated with data obtained from the Chandra X-Ray Observatory, indicated that one of these black holes gener... |

Dolphins are considered the fastest sea mammals. Smaller dolphins reach 35-40 km (22-25 mi) per hour, but the orca or killer whale, that is in fact the world's largest dolphin, reaches 54 km (33 mi) per hour, which is a lot in the water. The question is: why not faster? The answer is given by a new research publ... |

What does an electron look like? Is it round, is it a cube, or what? So far, no one has been able to see an electron directly, because photons from a beam of light directed at the electron alter the position of the electron, so they can't bounce back into the eye to form an image. The electron is a fundamental ... |

Physicists observed nanoscale bubbles of air forming in water for the first time in 2001. The only problem is these bubbles were not supposed to exist. Still, they continue to contradict the laws of physics and pop up unexpectedly.Air can form bubbles in water and these can last for a long time until breaking. The p... |

If your PC gets into the water, after that you can throw it to trash. But the future philosophy of making computers may be based on a watery support. Plain nitrogen bubbles, directing the flow of liquid through networks of microscopic microfluidic tubes, could act as computer bits by sending liquid in one way or anot... |
