Izinkinga

Ingxenye ethi “Izinkinga” isikhanyisela ngezinhlobo zokuhlupheka ezisakazekile nezivame ukucasha izilwane ezibekezelela ezweni eligxile kumuntu. Lezi akuzona nje izenzo zonya ezingahleliwe kodwa izimpawu zohlelo olukhudlwana—olwakhelwe phezu kwesiko, ukunethezeka, kanye nenzuzo—olwenza ukuxhashazwa kujwayelekile futhi lunqabele izilwane amalungelo azo ayisisekelo. Kusukela ezilaheni zezimboni kuya ezinkundleni zokuzijabulisa, kusukela emakheji aselabhorethri kuya ezimbonini zezingubo, izilwane zibhekana nokulimala okuvame ukuhlanzwa, ukunganakwa, noma okuthethelelwa imikhuba yamasiko.
Isigatshana ngasinye kulesi sigaba sibonisa isendlalelo esihlukile sokulimala. Sihlola ukwesabeka kokubulawa nokuboshwa, ukuhlupheka koboya nemfashini, kanye nezilwane ezihlukumezekile ezibhekana nazo ngesikhathi sokuthutha. Sibhekene nomthelela wemikhuba yokulima kwasefekthri, izindleko zokuziphatha zokuhlolwa kwezilwane, nokuxhashazwa kwezilwane emasekisini, eziqiwini nasemapaki olwandle. Ngisho nasemakhaya ethu, izilwane eziningi ezingabangane zibhekana nokunganakwa, ukuhlukunyezwa kokuzalanisa, noma ukulahlwa. Futhi endle, izilwane ziyaxoshwa, zizingelwe, futhi zithengiswe—ngokuvamile egameni lenzuzo noma ukunethezeka.
Ngokudalula lezi zinkinga, simema ukuzindla, umthwalo wemfanelo, kanye noshintsho. Lokhu akukona nje unya—kumayelana nendlela ukukhetha kwethu, amasiko, kanye nezimboni ezidale isiko lokubusa phezu kwabasengozini. Ukuqonda lezi zindlela kuyisinyathelo sokuqala sokuzidiliza—nokwakha umhlaba lapho uzwelo, ubulungisa, nokuphilisana kuqondisa ubudlelwano bethu nazo zonke izinto eziphilayo.

Eminyakeni yamuva nje, umhlaba ubone ushintsho olukhulu emkhakheni wocwaningo lwesayensi, ikakhulukazi emkhakheni wokuhlolwa kwezokwelapha nezimonyo. Ukuhlolwa kwezilwane kwendabuko, okuke kwabonwa njengendlela edingekayo yokuqinisekisa ukuphepha nokusebenza ngempumelelo kwemikhiqizo, kuya kuphonselwa inselelo ngokufika kwezindlela zokuhlola okungezona ezesilwane. Lezi zindlela ezintsha azithembisi nje ukuba nobuntu kodwa futhi zizoshesha, zishibhile, futhi zithembeke kakhulu kunozakwabo abasekelwe ezilwaneni. I-Cell Cultures Amasiko amaseli abe yithuluzi elibalulekile ocwaningweni lwesayensi lwesimanje, olwenza ososayensi bakhule futhi bafunde amangqamuzana omuntu nawezilwane ngaphandle komzimba. Cishe zonke izinhlobo zamangqamuzana omuntu nezilwane, kusukela kumangqamuzana esikhumba kuye kuma-neuron namaseli esibindi, zingakhuliswa ngempumelelo elabhorethri. Lokhu kuye kwavumela abacwaningi ukuba bahlole ukusebenza kwangaphakathi kwamaseli ngezindlela ezazingenakwenzeka ngaphambili. Amasiko amaseli atshalwa ezitsheni ze-petri noma amaflask agcwele ...
