We could say that Viagra is on the way to save lives. And it's not about sexual life; Viagra (sildenafil) could prolong the lives of people suffering from muscular dystrophy, as pointed out by a new research published in the journal Proceedings of the National Academy of Sciences. Just as it works against impote... |

In the end, they were right when they gave Popeye, the cartoon sailor, spinach instead of garlic as enhancement for his supernatural powers. For long, spinach was said to be rich in calcium and iron (later researches proved this was just rubbish), but a new research has, for the first time, proved its ability to boos... |

There's nothing faster on the ground than a cheetah on the hunt. The maximum speed is of 112 km (70 mi) per hour, but the average hunting speed is still of 72-90 km (46-56 mi) per hour. The elastic spine and the long legs allow the cheetah to make successive jumps 7 m (23 ft) in length each and in 2 seconds a ch... |

It is by far the largest living lizard: the Komodo dragon (Varanus komodoensis) grows over 3 m (10 ft) in length, weighing over 154 pounds (70 kg). But even if the giant monitor lizard manages to kill animals as large as water buffaloes (and in the past it may have feasted on pygmy elephants), its bite is relatively... |

What is the connection between a cold and big muscles? Compared with a placebo drug, the daily-recommended dosages of ibuprofen and acetaminophen (paracetamol) have been found to induce a significant higher growth of quadriceps muscle mass and strength gained in three months of regular weight lifting, as revealed by ... |

I always heard people saying that you can't have too much of a good thing and that excesses are bad - you know, those boring cliches that we so easily dismiss and imagine that there's absolutely no degree of novelty or relevance in them. Well, we may be right most of the times, but nevertheless - sometimes,... |

Every skeletal muscle fatigues, more or less rapidly, but why is that? It has been believed for almost a century that muscle fatigue is caused by lactic acid, produced during exercise and thought to impair contractile proteins. But studies made in the last years showed that, at body temperatures, very little acid sto... |

Botox injections employ the most dangerous naturally occurring toxin: the Botulinum toxin. It is the trademark of Clostridium botulinum bacterium and less than 2 kg (5 pounds) would be enough to wipe out the whole human population (the botulinum toxin is 40 million times more powerful than cyanide). But in extremely ... |

1. You continuously hear about the health state or the accidents suffered by sport stars. Even you can experience small lesions, a wrench or a muscular contracture without making sport. But, in the case of practicing a sport, even the character of the person can harden the treatment. Many sportsmen, even when amateur... |

In other times, people had to hunt animals and gather plant food for a living. At the same time, they had to avoid predators, while sheltering in caves or miserable huts. Our bodies had to be fit and strong in order to survive. But in the last millennium, and especially last centuries, technology reversed this. Our c... |

1.The scaffold of our body is made of 206 bones, joined through articulations. The largest human bone is the femur (about 50 cm or 20 in long), while the smallest is the stapes (2.6 mm or 0.1 in) from the middle ear. 2.There are 4 categories of bones: long (cylindrical) which are stretched and slightly curbed, having... |

From an eyebrow trembling to jumping, all is made by the muscles. Without them we could not even digest food or circulate blood inside the body. 1.There are three types of muscles: skeletal, responsible for the voluntary movements (from a smile to climbing the stairs); smooth, which make slow, involuntary movements ... |

The lymphatic massage is a delicate, light form favoring the lymph flow. It is based on light, rhythmic and constant movements, only touching the skin, with an almost non-perceptible pressure. Being so fine, the patient may perceive it as useless, but after two-three sessions, its benefits can be seen. A lymph massag... |

1.The speech skill is a wonder. To produce a phrase, about 100 muscles of the chest, neck, jaw, tongue and lips must collaborate. Each muscle is a bundle made of hundreds or thousands of fibers. For the coordination of these muscles much more neurons than necessary are required for contracting the muscles from an ath... |

"You snooze, you lose". Is that so? All vertebrates sleep, from fish to mammals, and birds even take naps while flying! Even some invertebrates, like insects, sleep. An animal deprived of sleep dies sooner than if it lacks food, because sleep is an imperative metabolic need.The stress induced by the urban life impair... |

Why does the cat always land on all four legs? Why do we keep on breathing, even if we sleep? This is the result of reflexes - automatic reactions that are not consciously controlled. Reflexes can be varied, from simple like retreating hand in contact with a hot object, to more complicated ones, that help us maintain... |

Our vulnerability is really located in the Achilles tendon. Even if standing upright, if they lacked an Achilles tendon like in chimps and gorillas, early humans would have been slower than a snail race. "Reverse-engineered" computer models point that in this case, our ancestors would have had difficulties in running... |

You can say that a four-limbed animal is running when at a given moment all its four limbs are in the air or its gravity center moves up and down in a pogo stick-like motion.It is said that the elephant does not run because they simply cannot do it. But when an elephant speeds up, can that be called just fast walking... |

Some have it in their blood... jogging and running, I mean. Now scientists have also found why: because of a mutation that increases muscle endurance and which has become common in some human populations.The skeletal muscles contain two types of fibers (cells): fast fibers, which can burn sugars without oxygen (anaer... |

Imagine a piece of paper that would move and have the shape of a fish. A Harvard team led by biomedical engineer Kit Parker has developed thin sheets of elastic film studded with rat heart muscle cells that can turn this into reality. The muscle-bound sheets react to electricity, as muscles contract, bend and flex th... |

This is too fast for our eye. The soldiers of a lowly termite, Termes panamensis, snap their jaws at a speed that bypasses any other muscle-powered movement of any species.Marc Seid and Jeremy Niven of the Smithsonian Tropical Research Institute in Panama revealed that termites reach a speed of 70.4 m (220 ft) per se... |

Big bellies have been seen for a long time now as the main cause for the metabolic syndrome, a group of conditions leading to heart attack: prediabetes, diabetes, high blood pressure, and high cholesterol. By using new powerful imaging technologies, a team of Howard Hughes Medical Institute (HHMI) at Yale University ... |

The strong and prolonged contraction of a muscle during exercising causes sooner or later muscle fatigue. Researches showed that the fatigue increases while the glycogen stored in the muscles decreases. The glycogen is a glucose polymer, like an animal starch. When the muscle needs glucose to burn, the glycogen cuts ... |

She may not go to the gym, but she has much more muscles than a long-trained body builder. In the end, whippets should be only lean muscle….well, not that much, anyway. Wendy's look differs a lot from the usual long, lean and sleek look of her counterparts. This female dog was born with a genetic impairment whic... |

The electric organs are specialized organs, derived from the muscles or the nerve cell's axon, that can generate electric current, employed from catching the prey (electro-paralysis) to defense, orientation (electro-location, similar the way bats and dolphins use ultrasounds in ecolocation), or as a means of com... |

It's easy for a couch potato to think that what really matters are the mind and soul. But no matter what they say, the awful truth is women are really crazy for muscles. A new UCLA research reinforces the idea that muscular men are much likelier to have short-term affairs and many more sex partners."If you'... |

Any couch potato with high self-esteem will say his/her piggy shape is because he/she does not go to the gym. And the big muscles are just the result of hard effort and potentially everybody could display them if trained. Our body shape is the result of the combination of three tissues: muscular, bony and fatty. But ... |

You go to the gym, train hard for some months, but - holly s**t - you must pump iron for life to keep looking like that. A drug stopping the dismantling of the muscles would be your dream product to get rid of the gym for a while. As soon as we stop exercising, muscle proteins start melting; idle muscles just keep a ... |

Tyrannosaurus rex was the terror of the dinosaur world. Now researchers not only have calculated the power of its terrible bite, but also the secret behind it: its hardened snout. "Fused, archlike nasal bones are a unique feature of tyrannosaurids. This adaptation, for instance, was keeping the T. rexes from breaking... |

Bears do not really hibernate. They can awake very quickly from their winter sleep and their temperature, heart beat and pulse do not drop significantly. Anyway, they pass the winter in an immobility stage and they go out of their dens in a very good shape. In northern regions, like Canada or Siberia, bears can spend... |
