Ndani amene alibe chiyembekezo cha moyo wosakhoza kufa? Koma zoona zake n’zakuti timakalamba ndipo timafa. Nthawi ino gudumu la m'badwo umenewo likhoza kutembenuzidwira kwina. Kafukufuku woyeserera wochitidwa ndi gulu la ofufuza pa Harvard Medical School akuwonetsa izi.
Ayi, si nkhani yopeka ya sayansi. Gulu la ofufuza pa Harvard Medical School, lotsogozedwa ndi David Sinclair, wofufuza za biology ya mamolekyu, lachepetsa zaka za mbewa mu labotale!
Asayansi amanena kuti mitundu ina ya mapuloteni amatha kupanganso maselo akale kukhala maselo a tsinde. Pogwiritsa ntchito njirayi, adatha kubwezeretsa maso a mbewa mu 2020. Retina ya mbewa inawonongeka chifukwa cha ukalamba, koma asayansi adatha kukonzanso maselo a retina amenewo. Pogwiritsa ntchito izi, asayansi adachepetsa zaka za mbewa nthawi ino.
Mu 2006, wasayansi waku Japan Shinya Yamanaka adatha kukulitsa zaka zama cell akhungu. Anapambananso Nobel pa zomwe anapeza. Masiku ano, mankhwala oletsa kukalamba akugwiritsidwa ntchito kale m'chipatala kwambiri.
Ofufuza a pa Harvard Medical School akhala akuyesetsa kwa nthawi yaitali kuti asinthe ukalamba wa anthu. Poyesa mbewa ziwiri zobadwa nthawi imodzi, asayansi adapanga mapuloteni apadera komanso kusintha kwa majini mu imodzi mwa mbewa. Zadziwika kuti ngakhale mbewa imodzi inakula pang’onopang’ono, mbewa ina sinakhudzidwe ndi msinkhu wake.
Komabe, akatswiri anena kuti ngakhale kuti kafukufukuyu akulozera ku mbali zatsopano za sayansi ya zamoyo, palibe chifukwa chofikira pa mapeto pakali pano pa nkhani yonse, kufufuza mwatsatanetsatane n’kofunika.
