Tähän tulis kaikkia juttuja, mitkä on biologiasta, ja hauskoja.
Tällainen osui silmiin tänään, ja on kauhea ja mielenkiintoinen, ja luultavasti jonkun mielestä hauska. Valitettavasti englanniksi.
Zombie power: Harnessing parasite mind control
AS IT floats through the air, a spore of the fungus Ophiocordyceps camponoti-balzani seems benign. But when it encounters an ant its true nature is revealed. First, it punches its way through the insect's exoskeleton. Once inside, it begins to grow, consuming just enough of its host's tissues to leave it weakened but functional. Finally, when the fungus reaches sexual maturity, it releases chemicals into the ant's brain. Under their influence, the hapless insect makes its way to a popular ant meeting place, climbs a plant and clamps its jaws onto the underside of a leaf, just as the parasite consumes its brain. Days later, elaborate fungal reproductive structures shoot out of the insect's corpse, spores rain down onto the unsuspecting ants on the forest floor, and the cycle begins again.
Parasites come in all sorts of gruesome guises, from blood-sucking lice to eyeball-eating schistosomids. But there is something particularly disturbing about one that can control minds - and O. camponoti-balzani is by no means the only organism that can (see "More mind-controlling parasites").

Että siis jonkun vielä pienemmän ötökän (parasiitin) vaikutuksen alaisena muurahainen kävelee "zombiena" suositulle muurahaisten tapaamispaikalle, kiipeää kasviin, tarttuu hampaillaan lehteen, ja kuolee siihen, kun parasiitti tekee sen aivoista (suuret varmaan) uusia parasiitin siemeniä, jotka sitten pölläyttää toisten muurahaisten päälle!!
