Soo koob maqaalka:  Fikradda ah in carrabkaagu uu u kala qeybsan yahay "goobo" dhadhan kala duwan leh ayaa si weyn loo beeniyay - inkastoo nidaamka saxda ah ee dhacaya weli si liidata loo fahmay. laakiin hada, markii ugu horeysay ee saynisyahano ayaa waxay sameeyeen khariidad sawirada tooska ah ee carabka si ay u ogaadaan waxa dhaca markasta oo aan cunto galino afkeena waxay cadeyneysaa sida kelyaha dhadhanka ay u leeyihiin unugyo kala duwan kuwaasoo loo isticmaalo kala saarida shanta nooc ee dhadhanka Daraasad ay Harvard hogaanka u qabatay ayaa lagu cabiray calaamadaha dhadhanka ee carrabka markii ugu horeysay. saynisyahannadu waxay baareen unugyada kala duwan ee loo isticmaalo in lagu kala saaro dhadhanka ayna daawanayeen unugyadaasi sida ay u qabsadaan una shaqeeyaan molecules nool. Cilmi baarista waxaa sameeyay koox caalami ah oo ay ku jiraan Jaamacadda Qaranka Australia (ANU) iyo Dugsiga Caafimaadka ee Harvard. Waxay isticmaaleen qalab gaar ah oo loo yaqaano Microscope si ay sawir uga qaadaan unugyada ku jira carrabka jiirka. Iftiinka laydhka iftiinka leh ee ku yaalla jiirka ayaa sababay in qeybo kala duwan oo jiirka kamid ah iyo molecules-yada dhadhanka ay soo baxaan iftiin. Penguins waxay lumiyeen seddex ka mid ah shanta dhadhan ee lafdhabarta - macaan, qadhaadh iyo dhadhanka macaan, hilibka leh ee loo yaqaano umami - in ka badan 20 milyan oo sano kahor waligoodna ma aysan helin, sida ay ogaadeen cilmi baarayaashu. Cilmi baadhayaashu waxay sheegeen in hiddo-wadahaas la waayay ka dib markii heer kulka qabow ee Antarctica uu carqaladeeyay dareenka dhadhanka. Cilmi baadhayaasha jaamacadda Michigan ayaa sheegay in ay la yaabeen daahfurka. Sababtoo ah penguinsku waa cunayaasha kalluunka, luminta dhadhanka umami ayaa si gaar ah u jahwareersan, ayuu yiri hogaamiyaha daraasadda Dr Jianzhi 'George' Zhang, oo ah borofisar ka tirsan Waaxda U-M ee Ecology iyo Evolutionary Biology. Dr. Zhang waxa uu ka shakisan yahay in isbedelada dareemayaasha ay ku xiran yihiin cimilada qadiimiga ah ee qaboojinta dhacdooyinka Antarctica, halkaas oo penguins ay ka yimaadeen. Isticmaalka farsamada loo yaqaano 'intravital multiphoton microscopy', saynisyahannadu waxay awood u yeesheen inay kala saaraan unugyada dhadhanka ee ku jira buro kasta. Waxay kaloo awoodeen inay arkaan marinnada dhiiga ee gaadhaya ilaa 240 micron-- 240...
Daraasad ay Harvard samaysay ayaa markii ugu horeysay lagu ogaaday calaamadaha dhadhanka ee carrabka. Cilmi-baadhayaashu waxay baareen unugyada kala duwan ee loo isticmaalo in lagu garto dhadhanka. Waxay daawanayeen unugyada oo qabsanaya una shaqeynaya molecules nool. Cilmi baadhayaashu waxay hada rabaan inay bartaan sida maskaxdu uga jawaabto dhadhanka.
