Insects do not have a sense of smell per se, in the way we define it. They respond to chemicals in their environment like humans and higher mammals do, but are not equipped with a nose, nostrils, and smell receptors. Rather, a new study has revealed, they have specialized proteins that perform about the same role. Th... |

Love can turn our world upside-down, it is often said, with good reason nonetheless. Yet, a recent research shows that it’s not just the “world” in general that love changes, but also something as intimately ours as our sense of smell – women in particular are most affected by it, in that they... |

The general concept says that birds are almost devoid of olfaction. Anyway, our weak noses would make them shame. But recent researches have showed it's not like that. New World vultures and condors have a smell that would compete with that of the dogs. Experiments made on newly-hatched chickens showed that the ... |

Homosexuality is regarded as unnatural, but that's nonsense: nature abounds in examples of homosexual behavior in animals. Various biological hypotheses say that the genes conferring homosexuality in human and animal males could deliver more fertile female offspring and the genes that confer high masculinity can... |

Just by a sniff, a dog can tell if you're a chicken or a trusty person, if it's better to avoid you or to beg for food and affection. But, a new research, made at the Northwestern University and published in the "Psychological Science" journal, showed that humans used infinitesimal scents, too, for assessi... |

Some say that in a world of senses, taste is the queen. It is a pleasure, but also a protection that can tell the difference between what's good to eat and what could be harmful. Still, taste is so personal, that many have linked it to the personality of the individual. Some are sweet, others are not, and make a... |

You know the typical 'skunk' in each company. It can be big, hairy and very pleased at how people panic when they see him. He should know that it's not the mighty blubber-filled body that which makes an impression on them; they are rather looking for the gas mask. But don't blame him for that...as... |

Not all the people are perceived in the same manner by elephants. A Maasai warrior clothing can induce dread in African elephants, driving them to the safety of tall grasses. These war shepherds occasionally spear elephants as a sign of virility (in fact, a Maasai is not considered a man till he has not killed a lion... |

This is how we investigate the chemical composition of our environment: through smell and taste. 1.The olfactory sensors are located in the upper nose, in the olfactory mucosa. The mucosa contains millions of olfactory cells (ciliated cells). Each ciliated cell contains over 12 cilia. The mucous maintains the humidit... |

Sexual attractiveness is much more than a look. Even if 80 % of the information we receive about our partner is visual, there is more. Researches have shown that women who look more attractive also smell better. At least at certain periods of the month, while symmetrical men, found very attractive by women, do smell ... |

You may have read about animals and humans with two heads or more than four legs. But all these occurrences were determined by developmental impairments, and if those individuals survived, they usually were either sterile or had normal offspring.

The most recently discovered orchid, endemic to Yosemite National Park, spreads a foul scent. It was exactly the stinky smell that attracted the attention of its re-discoverers, as the plant was first coll... |

Balkan wars in the '90s left a "hard" inheritance: the landmines. Croatia, Bosnia-Hercegovina and the other countries of the former Yugoslavia, were intensively mined. Over 1,000 sq km (380 sq miles) of Croatian countryside is infested by the mines. About 250,000 mines are still under ground, and made about 100 ... |

In the constant struggle between prey and predators, plants can employ the most disgusting chemical methods to keep away vegetarians. Even so, co-evolution can make herbivores bypass these defenses. Such is the case of a species of fruit fly, Drosophila sechellia, for example, which enjoys the fruit of a Polynesian s... |

In most mammals' case, the nose is the primary organ for smelling. As the animal sniffs, the air flows through the nose and over structures called turbinates in the nasal cavity. The turbulence caused by this disruption slows the air and directs it toward the olfactory epithelium. At the surface of the olfactor... |
