"Strange But True"

Best Sniffers

From  food aromas to toxic fumes, the human nose does a fine job of distinguishing various scents.  But man is not the best sniffers.  The bloodhound, has a smelling mechanism within it's nose that is fifty times larger and one million times more sensitive than the human nose.  According to research, the dog can distinguish between two trails that are several days old.  But do you know when it comes to sniffing, bloodhounds are not match for the male silkworm moth.  Nevertheless, males can pick up her scent as far as seven miles.

Animal Psychic

The catastrophic Chinese Haicheng earthquake of 1975 was preceded by many reports of unusual animal behavior.  Beginning in December 1974, lay observers noted dazed rats and snakes that appeared to be "frozen" on the roads.  Reports of this type increased markedly, that there is an observations of general restlessness and agitation of the larger animals such as cows and horses.  Chinese scientists seem convinced that such animal behavior might help predict larger earthquakes.

Drunken birds

Is there such thing as drunk pelican?  Four brown pelicans were brought in for intoxication test at a Wildlife Center in Southern California in June 2006, after one of them rammed a car.  The pelican was apparently drunk.  The other three were found dazed and confused in the swanky streets.  Official at the Wildlife Care Center said that  the larger seabirds may have been under the influence of intoxicating algae that produce domoic acid.  Domoic acid is a substance believed to have caused several peace-loving seabirds to act "wildly".  The first pelican was treated for injuries.  The other three were allowed to "sober up".

            

What are pheromones?

From the Webster's Dictionary it is describes as "a chemical substance produced by an animal that serves as a stimulus to other individuals of the same species for one or more behavioral responses".  In short it is an odor produced by an animal or plant that affects the behavior of others- like animals and plants.  When attacked by predators, bees and aphids emit alarm pheromones that stimulate other bees to fight and aphids to flee.  Some plants also give off pheromones when they are grazed upon.  Other plants produce chemicals that poison the animals feeding on them.

            

Sex-role Reversal

Many males in the animal kingdoms are the ones that get pregnant, provide brood care to the embryos, and give birth to the young.  One example is the Gulf pipe fish which belongs to the same family as Seahorse.  It is the male pipe fish that gets pregnant, gives birth, and raises the offspring.  As for the mommy pipe fish, she swims away without care in the world, after impregnating the male.  Researchers used a bit of genetic archeology to obtain clues to the "great gender mystery" of how male pregnancy evolved in a family of fish.  Why these things happen is one of the more difficult phenomena for evolutionary biology to explain.

            

Malaria busters

By introducing genetically modified mosquitoes in the wild, scientists believe that the malaria-resistant insects would be able to wipe out their disease-carrying conterpart.  According to research team the modified mosquitoes have a higher survival rate and laid more eggs.  From the laboratory experiments conducted, the researchers' findings indicate that when the genetically modified mosquitoes where allowed to breed with "wild type" mosquitoes, about 70 percent of the insects reproduced belonged to the malaria-resistant strain.  This strategy could very well be the newest and trickiest way to combat malaria effectively says a scientist.

Light death

We usually think light is good, and more light can only be better.  But too much of anything can be harmful.  Lights on tall structures, such as skyscrapers, can disorient migrating birds.  The birds often crash into brilliantly-lit broadcast towers or buildings until they drop from exhaustion.  The United States Fish and Wildlife Service has estimated that the number of birds killed after being attracted to tall towers range from four to five million per year.
