Pfupisa nyaya yacho:  Pfungwa yokuti rurimi rwako rwakakamurwa kuva <unk>zones<unk> nokuda kwezvinonaka zvakasiyana-siyana yakarambwa zvikuru - kunyange zvazvo muitiro chaiwoiwo uri kuitika uchiri kunzwisiswa zvishoma. Asi iye zvino, kekutanga, masayendisiti akagadzira mepu inoratidza zvinenge zvichiitika kumanzwiro orurimi kuti aone zvinoitika pose patinoisa zvokudya mumiromo yedu. Inoratidza kuti tunhu tunonhuwira twune masero akasiyana-siyana anoshandiswa kusiyanisa pakati pemapoka mashanu makuru ezvinonhuwira. Chidzidzo chakatungamirirwa neHarvard chakanyora nzvimbo dzokunaka parurimi kwenguva yokutanga. Masayendisiti akaongorora masero akasiyana-siyana anoshandiswa kuziva kuravira ndokucherechedza masero aya achitora nokugadzira mamorekuru ari mhenyu. Mufananidzo uri kuratidzwa ndewekunzwa kuravidza kunenge kune masero anogamuchira (green), masero eropa (red) uye collagen yakakomberedza bud (blue) Tsvakurudzo iyi yakaitwa nechikwata chenyika dzakawanda chaisanganisira Australian National University (ANU) neHarvard Medical School. Vakashandisa maikorosikopu akagadzirwa nomushonga uyu kuti vaone masero ari parurimi rwemakonzo. Kupenyera rurimi rwegonzo nelaser inopenya yeinfrared kwakaita kuti zvikamu zvakasiyana-siyana zvarwo uye "mamorekuru anonhuwira" zvipenye. Vanzveri vakawana kuti makore anopfuura mamiriyoni 20 akapfuura, mapenguin akarasikirwa nezvinonaka zvitatu zvezvishanu zvinokosha zvemhuka dzine mitsipa - zvinotapira, zvinovava uye zvinonhuwira, zvinonaka zvine nyama zvinozivikanwa seumami - uye haana kuzvitorazve. Vanzveri vanoti majini akarasika pashure pokunge tembiricha inotonhora yeAntarctic yapindira mukurangarira kuravira. Vatsvakurudzi vepaUniversity of Michigan vakati vakashamiswa nokuwana uku. Nemhaka yokuti mapenguin anodya hove, kurasikirwa nokuravira umami kunonyanya kuvhiringidza, akadaro mutungamiriri wefundo Dr Jianzhi 'George' Zhang, purofesa muU-M Department of Ecology and Evolutionary Biology. Dr. Zhang vanofungidzira kuti kuchinja kwemanzwiro kunobatanidzwa nezvakaitika kare zvokutonhora kwemamiriro okunze muAntarctica, kwakatangira mapenguin. Vachishandisa nzira inonzi intravital multiphoton microscopy, masayendisiti akakwanisa kuona masero anoravidza ari mukati mebudza rimwe nerimwe. Vakakwanisawo kuona tsinga dzeropa dzakasvika pama240 micron - 240...
Chidzidzo chakatungamirirwa neHarvard chakaronga makonzo orurimi parurimi kwenguva yokutanga. Masayendisiti akaongorora masero akasiyana-siyana anoshandiswa kuziva kuravira. Vakaona masero acho achibata uye achigadzira mamorekuru ari mhenyu. Vaongorori vava kuda kudzidza kuti uropi hunoita sei kana hwaravira chimwe chinhu.
