Izazinzulu zathetha ngefuthe lokwaphula imithombo ye-paquadian kwiDNA yomntu
Uphando olutsha lwenzululwazi lwenziwe kwisiseko selebhu yokulala yaseWashington State iveze impembelelo yomsebenzi wobusuku kwimpilo yabantu. Ukophulwa kwemijikelezo yesekethe kunokukhokelela kutshintsho kwimbonakalo yemfuza ehambelana namathumba amaninzi. Iziphumo zomsebenzi owenziweyo zapapashwa kwiMagazini eNew Atlas.
Kuyaphawuleka ukuba ngo-2019 i-Arhente yoMhlaza yeHlabathi yazisa iingozi zomsebenzi ebusuku. Amagama aseMaire ayeqinisekiswa ngexesha lovavanyo achitha ngaphezulu kweentsuku ezisixhenxe ngokuthatha inxaxheba kwamavolontiya anempilo. Isiqingatha sokuqala sezifundo sisebenzise utshintsho ezimbalwa ngexesha lasemini, kwaye okwesibini bubusuku. Emva koko, kwakufuneka bachithe iiyure ezingama-24 kwimeko yokuvuka phantsi kokukhanya rhoqo. Oku kuvumela izazinzulu ukuba zifunde isingqisho sendalo sabantu, nokuba yeyiphi na into yangaphandle.
Uhlalutyo lubonise ukuba ishedyuli yokusebenza yasebusuku idubule phantsi kwemijikelezo yesekethe yezifundo, ezikhokelela ekuphulukaneni neentlobo ezithile zemfuza ezinxulumene nokuphuhliswa kwenkqubo yokusebenza. Iingcali zikwatyhila ifuthe elibi lomsebenzi ebusuku kwi-DNA yokubuyisela kwendalo yendalo.
Ngophando oluneenkcukacha ngakumbi lwesiphumo sokwaphula intetho ethile kwiiseli ezinesempilweni emzimbeni, izazinzulu zihlalutya iiseli ezimhlophe zegazi, ezichaphazela ukusebenzisa imitha ye-ionif. Kwavela ukuba iiseli zeqela labantu ababesebenza kubusuku betshintshana nge-shift ebusuku babethathwa njengomonakalo we-radiation we-radiation.
Ezi ziphumo zibonisa ukuba i-shience yasebusuku idinisa ukusebenza kwentetho yemfuza yomhlaza, ngoko ke inciphisa ukusebenza kweenkqubo ze-DNA yomzimba, xa zifuneka kakhulu, i-jason mcdermott, umbhali we-jason mcder.Izazinzulu zaphawula ukuba isifundo esitsha khange sibavumele ukuba bafumane iimpendulo kuyo yonke imibuzo. Njengenxalenye yenqanaba elilandelayo, kucwangcisiwe ukuhlalutya i-DNA yabantu abasebenza ngokusebenza ebusuku ukuze bathelekise iziphumo zovavanyo zabasebenzi ebusuku. Abaze bakhuphe amathuba okuba ixesha elide, umzimba unokuziqhelanisa nomsebenzi.
