Eating one small square of dark chocolate daily keeps heart-related diseases and their consequences at bay, according to an Italian study. Almost every little thing you like to eat (or drink or inhale or feel) is generally labeled as being bad for health and officially accompanied by a warning. But many of these... |

We know that eating one's poop is very unhealthy. What we do not know instead is whether cheetahs are aware of this, but they can die if they take up this "practice", as signaled by a new research published in the Proceedings of the National Academy of Sciences. In fact, they catch a disease similar to the mad c... |

Don't let its name scare you - the three-apples-a-day diet involves a lot more than starving yourself by eating nothing else except three apples a day. This diet is in fact a long term weight loss solution developed by American dietitian going by the name of Tammi Flynn, who holds a Master's degree in Nutri... |

T-Rex is by far the most famous of dinosaur species. For 150 years, Tyrannosaurus rex was considered the largest carnivorous species that have ever roamed the earth. And it was, indeed, a huge beast - up to 12.8 (42 ft) in length and 7.2 tonnes in weight. Bigger than an elephant! Meanwhile, in 1993, a longer carnivor... |

It's elastic, stronger than steel, it has light weight and we can't fabricate it. At least not up until now. After decades of trying to replicate it in experiments ranging all the way from lab dishes to silk-secreting goats, German researchers have succeeded in creating an artificial spider duct that can &#... |

You may depreciate creeping creatures like snakes and lizards, but the first mammals, the group which humans belong to, evolved from egg-laying reptiles. By feeding the young with milk, mammals skipped the yolk diet and the egg stage in their development. A new research published in the journal "PLoS Biology" has tra... |

Proteins are everywhere in your body. They have two functions: functional and structural. Functional proteins are called enzymes; they modulate everything in your body, directly or indirectly, through synthesis of hormones, neurotransmitters and other chemicals. But proteins also build any tissue, from skin, bones an... |

The spider silk is extremely lightweight but at the same time as strong as steel, even if its structure is based on molecular forces 100 to 1,000 times weaker than those encountered in the steel's metallic bonds, or even Kevlar's covalent bonds.

120 grams of lean beef contain 25 grams of high quality proteins, almost totally assimilable, unlike the plant proteins, which the body assimilates just in a proportion of 50-65 %.

"We are what we eat". The food we eat has various chemicals with different functions: some deliver "building blocks" for our body components (bones, muscles, hair, teeth, nails) and repairing material. Others come with energy or eliminate toxins. That's why the diet must be balanced, a fact reflected in the ove... |

There are cases when death can be a really good thing. Imagine, for instance, the cancer cells. However, so far, only two ways of cell death have been known: apoptosis (when the cell destroys itself) and phagocytosis (when the cell is digested by another cell). Now a new type of cell death has been found: entosis, wh... |

Both X c... |
