Kev tsis txawj tuag: Cov kws tshawb fawb tau txo cov hnub nyoog nas, puas rov qab kev laus ntawm tib neeg tam sim no ua tau?

Cov ntsiab lus ntawm txhua lub neej hauv ntiaj teb no yog, "kev lwj thiab kev tuag." Tab sis lub sij hawm no lub log ntawm cov txheej txheem kev laus tuaj yeem tig mus rau qhov sib txawv.

Leej twg tsis muaj kev cia siab ntawm kev tsis txawj tuag? Tab sis qhov tseeb yog tias peb muaj hnub nyoog thiab peb tuag. Lub sijhawm no lub log ntawm lub hnub nyoog tuaj yeem tig mus rau qhov sib txawv. Ib qho kev sim ua los ntawm ib pab neeg tshawb fawb ntawm Harvard Medical School qhia qhov ntawd.

Tsis yog, nws tsis yog ib zaj dab neeg txog science. Ib pab neeg tshawb fawb ntawm Harvard Medical School, coj los ntawm David Sinclair, tus kws tshawb fawb hauv molecular biology, tau txo qis hnub nyoog nas hauv chav kuaj!

Cov kws tshawb fawb tau hais tias qee hom proteins tuaj yeem tsim cov hlwb qub rau hauv cov qia hlwb. Siv txoj kev no, lawv muaj peev xwm rov kho qhov muag pom ntawm tus nas xyoo 2020. Tus nas lub retina tau puas los ntawm kev laus, tab sis cov kws tshawb fawb muaj peev xwm rov tsim cov hlwb retinal. Siv qhov kev paub no, cov kws tshawb fawb tau txo cov hnub nyoog ntawm tus nas lub sijhawm no.

Xyoo 2006, tus kws tshawb fawb Nyij Pooj Shinya Yamanaka tuaj yeem ua kom muaj hnub nyoog ntawm daim tawv nqaij. Nws kuj yeej Nobel rau qhov kev tshawb pom ntawd. Niaj hnub no, kev kho mob ntawm daim tawv nqaij los tiv thaiv kev laus twb tau siv rau hauv kev kho mob ntau.

Cov kws tshawb fawb ntawm Harvard Tsev Kawm Ntawv Kho Mob tau tshawb nrhiav ntev los hloov cov txheej txheem kev laus hauv tib neeg. Hauv kev sim ntawm ob nas yug tib lub sijhawm, cov kws tshawb fawb tau ua cov protein tshwj xeeb thiab kev hloov kho caj ces hauv ib qho ntawm cov nas. Nws tau raug pom tias txawm tias ib tus nas maj mam loj tuaj, lwm tus nas tsis cuam tshuam los ntawm nws lub hnub nyoog.

Txawm li cas los xij, cov kws tshaj lij hais tias thaum txoj kev tshawb fawb taw qhia rau lub qab ntug tshiab hauv kev ua liaj ua teb ntawm biology, tsis tas yuav los txiav txim siab tam sim no ntawm tag nrho cov teeb meem, xav tau kev tshawb fawb ntxaws ntxiv.
