Vegetarianism is a diet that promises countless benefits, from a healthier heart to better skin and a boost of energy, as compared with the regular diet that also includes meat. However, when deciding to make the switch from regular to vegetarian, aside from the inevitable cravings, other side-effects may appear, whi... |

For quite some time now, a lot of people have argued that the Moon “flashes” from time to time, in that variations in the luminescence of some of its regions change briefly at certain times. According to a recent investigation, conducted by Columbia University in New York (CUNY) Astronomer Arlin Crotts, t... |

There seems to be a constant rush as of late to demonstrate that what we used to know and treat as a given is wrong. Evolving technology and the increased amount of accurate scientific data provide more insight on many of these aspects that were not thoroughly investigated so far. As such, it appears that the prevale... |

Depending on the gas and its temperatures, the atoms begin to spin rapidly, forming a quantum tornado. This allows scien... |
