Eminyakeni embalwa edlule, ososayensi abavela e-Massachusetts Institute of Technology bakhathazeka ngezinkinga zokugoma emazweni asemuva nasathuthuka. Ezindaweni ezinjalo, ngokuvamile alukho uhlelo lokubhaliswa kwabantu esibhedlela noma akwenzeki. Khonamanjalo, imigomo eminingana, ikakhulukazi ebuntwaneni, idinga ukubambelela ngokuqinile esikhathini kanye nezikhathi zokulawulwa kokugoma. Ukugcina kanjani futhi, okubaluleke kakhulu, ukuqaphela ngokuhamba kwesikhathi ukuthi yini futhi nini imigomo edingekayo kumuntu ngamunye? Ikakhulukazi uma lesi sidalwa siwela ezandleni zomuntu osuka enhlanganweni efana neDoctors Without Borders.
Ososayensi abavela eMIT ubuchwepheshe bokugoma kanye nokwethulwa kanyekanye kwephethini efakwe ikhodi yezinto ezinamachashazi e-quantum ngaphansi kwesikhumba. Emdwebeni ungafaka idatha mayelana nesikhathi sokugoma, mayelana nokugoma ngokwawo, ngisho nangenqwaba lapho umuthi uthathwe khona. βUmbhaloβ odaliwe awubonakali ngeso, kodwa ungafundwa kusetshenziswa i-smartphone eguquliwe enekhamera engenaso isihlungi se-infrared. Amachashazi e-quantum asuselwe kwikhopha ajabule endaweni eseduze ne-infrared futhi angafundwa ngaphansi kongqimba olungaphezulu lwesikhumba ngisho neminyaka emihlanu ngemuva kokufakwa (ahlolwe ezimeni zaselabhorethri kumasampula esikhumba somuntu).
Indlela yokusebenzisa idizayini yolwazi kanye nokunikeza umgomo kanyekanye ihlanganisa ukusebenzisa isiqeshana sokugoma kunesirinji. Umuthi wokugoma nodayi kuvalelwe into evumelana ne-biocompatible futhi encibilika kancane, inhlanganisela yoshukela ne-polyvinyl acetate (PVA). Le nto isetshenziselwa ukwakha izinaliti ezinde ezingu-1,5 mm ezibhoboza ungqimba olungaphezulu lwesikhumba bese luncibilika. Ukubekwa kwezinaliti nakho kuthwala ulwazi, njengoba zijova udayi ngamachashazi we-quantum wezinga le-nanometer (cishe u-4 nm ububanzi) ngaphansi kwesikhumba ngendlela enikeziwe. Ukuhlolwa kwamagundane aphilayo kubonise ukuthi ukugoma ngale ndlela kunikeza umphumela ofanayo nokugoma ngesipetu.
Okungenani abantu abayizigidi eziyi-1,5 bayafa minyaka yonke ngenxa yokuntuleka kwemijovo noma ukugoma. Uma indlela entsha yokugoma enerekhodi lezokwelapha esikhumbeni sesiguli iba nokwenzeka, izosiza ekusindiseni izimpilo eziningi.
