Golden tortoise beetle: chipembenene chakakosha

"Uye ipapo kamwe kamwe mumwe muKhanom kana kumaodzanyemba kweThailand, kana uchida, anondinongedzera kune chipembenene chakakosha chandaisaziva kuti chiriko," anonyora Monique Rijnsdorp. Saka akatanga kuferefeta achibva aona kuti golden tortoise beetle ine imwe nzira yokuchinja ruvara.

Zvinonyatsozivikanwa kuti zvisikwa zvipenyu zvakawanda zvinoshandura ruvara senzira yekuvhara. Zvinhu zvipenyu zvakaita sechameleon nesquid zvinochinja ruvara kuburikidza nekugadziridzwa mune mamwe maseru akakosha anotakura makemikari ane mavara: pigment cell. Asi nzira yegold turtle beetle yakasiyana.

Chipembenene ichi chinozivikanwa zvakare nezita charidotella egregia uye inogona kukura kusvika 8 millimeters. Inosanganisira sleeve inoonekera. Iri sleeve rinowanzoratidza ruvara rwesimbi yegoridhe. Asi kana kapembenene kacho kasina kugadzikana, ruvara rwegoridhe runochinja kuita rutsvuku.

Vatsvakurudzi vepaYunivhesiti yeNamur vakaongorora goko rechipembenene ichi vachishandisa maikorosikopu erekitironi uye vakawana kuti rine mativi matatu. Iyo gobvu layer ndeyepasi uye yakatetepa ndiyo yepamusoro. Mutsara wega wega une pasuru yezvidimbu zvidiki. Mutsara wega wega unoratidza chiedza mune rumwe ruvara. Pamwe chete, zviratidzo izvi zvinobudisa ruvara rwegoridhe. Pazasi pezvikamu zvitatu izvi pane dzvuku pigment layer.

Pane migero pakati pezvikamu zvese. Apo mvura yemuviri webete inozadza nzira idzi, zvidimbu zvinova zvakatsetseka uye, sezvinotaura musayendisiti weBelgium Jean Pol Vigneron, "magirazi akakwana" anogadzirwa. Nenzira iyi bete rinotaridzika kupenya uye simbi. Kana pasina mvura mumigero, zvidimbu zvinoshanda sehwindo panzvimbo yegirazi, sheath inorasikirwa nekupenya kwayo uye yakaderera pigment tsvuku inooneka.

Andrew Parker weOxford University anotsanangura iyi 'fluid-based mechanism' se 'iyo isati yamboonekwa muzvisikwa'.

Masayendisiti anotarisira kukwanisa kugadzira michina inogona kuratidza mamiriro emvura kuburikidza nechiedza uye ruvara mumamiriro akasiyana, zvichibva pane tekinoroji mugolden tortoise beetle.

Radislav Potyrailo, analytical chemist paGE Global Research Center muNew York, ane izvi zvokutaura pamusoro peiyi tekinoroji yakasarudzika mugoridhe torto beetle: "Zvisikwa hazvizomboregi kutishamisa nemhinduro dzakanaka dzezvinetso zvezuva nezuva."
