Ngalolu lwazi olusha, abacwaningi banesiqalo esikhuthazayo sokulawula umhlaba wonkeinani lomiyane.
Ithimba lososayensi abavela eVirginia Tech lishicilele imiphumela yocwaningo lwabo lwe-hormone yobuntwana (isignali yamakhemikhali ebalulekile ekuzaleni omiyane) ephepheni elanyatheliswa kumagazini i-Proceedings of the National Academy of Sciences.
Ngaphambilini, abacwaningi babekholelwa ukuthi ama-receptor amabili ahlukene ayedingeka ukuze ama-hormone asemancane asebenze. Bathole i-metopron tolerance receptor (MET) njengenye yawo, kodwa enye i-receptor isalokhu iyimfihlakalo.
Umcwaningi oholayo uZhu Jinsong uthole ukuthi i-MET isebenza ngaphakathi kweseli kanye naselwelweni lweseli. Amasu okuthwebula izithombe athuthukisiwe abonisa ukuthi iyasiza ekulawuleni intuthuko, ukuvuthwa, kanye nokwakheka kwama-oocyte okulandelayo.
Lapho abacwaningi bevimba isenzo se-MET endaweni ethile, ukuzala komiyane kwancipha kakhulu.
Esitatimendeni sabezindaba, uZhu uthe: “Omiyane besifazane kumele basebenzise amandla abo nezakhamzimba ngokucophelela ukuze babeke amaqanda, futhi uma le nqubo iphazamiseka, amandla abo okuzala ayancishiswa.”
Lokhu okutholakele kungase kunikeze enye indlela ephumelela kakhulu kunezibulala-zinambuzane zesimanje. Izibulala-zinambuzane zendabuko zisebenza ngokuhlasela isimiso sezinzwa somiyane, kodwa omiyane kancane kancane bathuthukisa ukumelana nala makhemikhali. Ngaphezu kwalokho, lezi zibulala-zinambuzane zingabangela umonakalo omkhulu kwezinye izinambuzane.
UZhu waphawula: “Umgomo wethu akukhona nje ukulawula inani lomiyane, kodwa futhi nokuthola izindlela ezithile zokunciphisa umthelela wabo ezinambuzaneni ezizuzisayo.”
Njengoba izifunda eziningi zomhlaba zibhekana nezimo zezulu ezishisayo nezinomswakama ezilungele ukuzalanisa omiyane, abacwaningi bahlola izindlela ezintsha zokuvimbela nokulwa nalesi sifo. Izinga elithusayo lapho umkhuhlane we-dengue usakazeka khona ezindaweni ezintsha liphawuleka kakhulu, ligcizelela isidingo esikhulayo sezinyathelo zokuvimbela nokulawula.
Igciwane le-Zika kanye nomkhuhlane ophuzi kuyizinye izifo ezithakazelisa abacwaningi. Lolu cwaningo lugxile kakhulu kumiyane i-Aedes aegypti, okuyimbangela eyinhloko yomkhuhlane ophuzi.
Ngokuthakazelisayo, njengoba uZhu ephawula, okutholakele kwabo kungase kusebenze kokungaphezu nje komiyane. Abanye abacwaningi bakholelwa ukuthi indlela efanayo ingasetshenziswa kwezinye izinambuzane. Uma izindlela ezifanayo zingasetshenziswa ukulwa nezinambuzane zezolimo, ucwaningo lwethimba luzoba usizo nakakhulu.
Ucwaningo olwengeziwe manje luyadingeka ngaphambi kokuba le miphumela ingasetshenziswa ukulawula ukuzalanisa omiyane.
Ithimba locwaningo lisebenza ukuze liqonde kangcono izindlela kanye nokusebenzisana kwe-MET. Lifunda ukuthi ukuphazamisa i-MET kungavimbela yini ukuzala ngaphandle kokubangela eminye imiphumela eyingozi.
UZhu waphetha ngokuthi: “Uma sifuna ukuthuthukisa amasu okulawula omiyane asebenza kahle futhi anesibopho semvelo, sidinga ukuqonda izici zezinto eziphilayo zomiyane ezingeni lama-molecule.”
Bhalisela iphephandaba le-TCD lamahhala ukuze uthole amathiphu awusizo, iseluleko esiwusizo, kanye nethuba lokuwina u-$5,000 kuphrojekthi yokuthuthukisa ikhaya. Ukuze ubone ezinye izihloko ezinjengalezi, shintsha izintandokazi zakho ze-Google lapha.
