Uma wake wahlangabezana nesimo sokungezwa emndenini wakho, impela udokotela noma uchwepheshe, ngaphambi kokuthi aqale ukusebenza, uzobe ekuxwayisile lokho indlebe ingenye yezinhlelo eziyinkimbinkimbi kunazo zonke umuntu okudingeka abhekane nazoInjalo-ke indaba yokuthi, lapho yephuka, yehluleka noma yonakala, cishe akunakwenzeka ukuyilungisa.
Ngalokhu engqondweni, namuhla ngifuna ukukutshela ngentuthuko entsha etholwe yiqembu labaphenyi elenziwe ososayensi abavela eChina nase-United States, ngenxa yobuchwepheshe. CRISPR, welapha ukuzalwa kokungezwa okuzelwe usebenzisa le njongo umjovo owodwa.
Kusetshenziswa i-CRISPR, iqembu labaphenyi kungenzeka ukuthi likwazile ukuthola ikhambi lokungezwa okuzelwe
Ukungena emininingwaneni ethe xaxa futhi ikakhulukazi kubhekwa okushicilelwe ephepheni ngenxa yalolu cwaningo, ososayensi ngokusobala kuye kwadingeka basebenze ukuze bathole umehluko phakathi kofuzo oluthintekile ngalolu hlobo olukhethekile lokungezwa noluthathwe kumuntu onempilo. Umphumela waba indawo ye- ukuguqulwa okuncane kwesakhi sofuzo se-TMC1 okwenza le geni ikhiqize iphrotheni elehlisa i-cilia.
Ngokusobala yilokhu kanye ukwehla kwe-cilia, okubhekele ukuguqula umsindo ube yimizwa yezinzwa, ekugcineni okubangela lokho okwaziwa ngokuthi isithulu sokuzalwa. Ukuze usinikeze umbono, vele sikutshele ukuthi ukuguquka kwezakhi zofuzo kuncane, kangangoba ikhophi lofuzo loqobo yehluka ngentambo ngokuguquka ngohlamvu olulodwa nje. Lapho inkinga isitholakele, ngomsebenzi ongaphezu kokuqapha, kwakudingeka kutholakale ikhambi layo.
Kuthatha umzali oyedwa kuphela ukuthi abe nale nkinga enganeni yakhe ayizuze njengefa
Ukuze siyiqonde kangcono inkinga yokungezwa okuzelwe, vele sikutshele ukuthi, ngokusho kososayensi, ngokusobala ukuhlupheka ngakho kuyadingeka kuphela ukuthi omunye wabazali ababili abe nayo. Lokhu ngokwanele ukudlulisela ezinganeni zakho. Njengoba uzobe ucabanga nje, noma kubonakala kuphambene, iqiniso ukuthi sibhekene noshintsho oluvame kakhulu emphakathini kunalokho esingakholelwa kukho.
Njengoba ephawule ezitatimendeni UFyodor Urnov, omunye wabalobi balo msebenzi kanye noprofesa e-Altius Institute for Biomedical Sciences eSeattle:
Kunjengokungathi abaculi ababili benza i-duet. Uma okukodwa kwalokhu kuphuthelwa, kufanele kuthuliswe ngokukhetha ukuze kuzwakale umculo ofanele. Asikwazi ukumisa bobabili abaculi ngasikhathi sinye, ngoba lowomculo uzophela.
Ngalokhu, lokho okushiwo nguFyodor Urnov ngokuyisisekelo ukuthi ekufuneni kwakhe ikhambi, bekungafanele nje kuphela ukuthi akhiqize isakhi sofuzo esishintshe ukuguquka kwezakhi zofuzo, kodwa futhi bekufanele azi kahle ukuthi siyini.
Imiphumela yalo msebenzi ijabulise wonke umphakathi wesayensi
Ukuze bathole ukwelashwa, ngokusobala ososayensi abasebenze kulo msebenzi basebenzise ukulandelana okuncane kwe-RNA ukuthola isakhi sofuzo okufanele singasebenzi. Ngenxa yalokhu, njengomphumela wesenzo, ushintsho olwenzile iphrotheni eyadala isithulu sokuzalwa yenziwa yangasebenzi.
Okwamanje kufanele kukhunjulwe ukuthi le phrojekthi isisesigabeni sokuqala kakhulu sokuthuthuka kwayo, yize imiphumela etholakele ingaphezu kokwanelisa. Okwamanje ukuhlolwa kokuqala kwenziwe kumagundane asanda kuzalwa okuthi, ngemuva kokuphathwa nangemva kwamasonto amane, amagundane amancane asenamandla okuphendula imisindo efinyelela kuma-15 decibel.
Noma kunjalo ucwaningo luselude ukhalo okumele luhambe kuze kube le nkinga yokuzwa ingalashwa kubantu, iqiniso ukuthi, njengoba umphakathi wesayensi uqobo ukhombisa, sibhekene nentuthuko engakaze ibonwe ngoba empeleni imiphumela ibajabulise kakhulu bonke abacwaningi abasebenza namuhla ukuthola isisombululo ezinkingeni ezithile zezokwelapha besebenzisa ubunjiniyela bezakhi zofuzo.
