We all know what the "overstuffed makeup bag" syndrome is all about, but if you're in need of some clarification, open any woman's cosmetics kit or go through her bathroom cabinets and have a look at her vanity table as well - you'll soon understand what "too much makeup" really means. And it's na... |

Some two decades ago researcher Richard Lenski of the Michigan State University started growing 12 laboratory populations out of a single Escherichia coli bacterium, which has evolved for over more than 44,000 generations ever since, thus accumulating even more genetic mutations. Although all 12 populations evolved s... |

How about replacing silica computer chips with a living organism, such as E. coli? Digital computers today are very fast, however researchers believe that living computers could prove one day a lot faster and powerful than any other silicon supercomputer. And just to prove the concept, they have created such a living... |

A very interesting piece of information to begin with is the fact that, unbeknown to most of us, feet actually have over 250,000 or more sweat glands - which means that when the weather gets hot (like it's happening right now), feet are one of the main doorways used by our body to try and cool itself off. Nothin... |

Yogurt has become such an integral part of our diets that we've grown used to taking its beneficial effects for granted, without asking too many questions with regard to its contents or the finer details of its inner workings. For the more yogurt-curious among you, here is a short guide to the many health benefi... |

Magnetite is a naturally occurring compound on Earth and some quantities can even be produced by bacteria on our planet. Considering that magnetism can be detected relatively easy with the help of instruments produced with the current technology, a future mission to the Red Planet could find and return magnetite mine... |

There are bacteria everywhere around us, and in infinite quantities. Some are good, some are neutral, but most people have in mind only the bad ones. 1. Tetanus is caused by the bacterium Clostridium tetani. It enters the body via an open wound and releases a powerful toxin, tetanospasmin. The incubation period lasts... |

It may seem silly: do pigeons represent a dangerous nuisance? The answer is: yes. Their dejections ruin monuments and statues. But it is more than that: they carry extremely virulent germs. Since Medieval Ages, the pigeons started to inhabit the European cities, where they easily found food in wastes discarded by hum... |

Botox injections employ the most dangerous naturally occurring toxin: the Botulinum toxin.

But in extremely ... |

This condition denotes infection or inflammation of the prost... |

All organisms catch infections, from plants to whales. Even some bacteria can get infected. 1.Pathogen microbes are of three types: viruses, bacteria and protozoans. Not all the microbes are infectious. Most bacteria are inoffensive. Escherichia coli from our gut has a role in digestion. Diseases appear when our immu... |
