Britanski strokovnjaki trdijo, da spermij za gibanje po teko\u010dini uporablja le eno stran repa. Da ne bi plavali v krogu, se podobno kot vidre vrtijo, da ohranijo smer.<\/p>\n<p>Klasi\u010dni mikroskop daje vtis, da se repki semen\u010dic premikajo simetri\u010dno z ene na drugo stran, je zapisal vodja \u0161tudije Hermes Gadelha, strokovnjak za podro\u010dje plodnostne matematike. &#8220;Spermiji so se prilagodili in svoje enosmerno plavalno gibanje izena\u010dili tako, da se v vodi vrtijo. Gibanje je podobno delovanju odpira\u010da za vinsko steklenico, torej podobno kot pri vidrah,&#8221; pravi Gadelha.<\/p>\n<p>Ta dodaja, da so spermiji re\u0161ili eno od matemati\u010dnih ugank v mikroskopskem merilu. Simetrijo so ustvarili iz asimetrije.<\/p>\n<p>\u0160tudija pa ima tudi uporabno funkcijo. Strokovnjaki trdijo, da bo v bodo\u010de na osnovi gibanja repkov mo\u010d prepoznati zdrave in nezdrave spermije.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u010clove\u0161ki spermiji plavajo podobno kot vidre, v novi \u0161tudiji trdijo raziskovalci, ki so na podlagi modernih 3D-mikroskopov ovrgli ve\u010d kot 300 let staro domnevo, da semen\u010dice plavajo s pomo\u010djo repka, ki se giblje levo in desno.
