Ka Holomua Kipi i ka ʻOihana Ikehu: Hoʻomohala nā kānaka ʻepekema i kahi ala hou e mālama ai i ka ikehu hou

I nā makahiki i hala iho nei, ua lilo ka ikehu hou i mea koho kaulana i nā wahie mōʻalihaku kuʻuna. Eia nō naʻe, ʻo kekahi o nā pilikia nui e kū nei i ka ʻoihana ikehu hou, ʻo ia ka loaʻa ʻana o kahi ala e mālama ai i ka ikehu keu i hana ʻia mai nā kumu hou e like me ka makani a me ka mana o ka lā. Akā i kēia manawa, ua hana nā kānaka ʻepekema i kahi ʻike hou e hiki ke hoʻololi i nā mea āpau.

Ua hoʻomohala nā kānaka noiʻi ma ke Kulanui o Kaleponi, ʻo Berkeley i kahi ala hou e mālama ai i ka ikehu hou e hiki ke hoʻololi i ka ʻoihana. ʻO ka holomua nui e pili ana i ka hoʻohana ʻana i kahi ʻano molekala i kapa ʻia ʻo "photoswitch," hiki ke omo i ka lā a mālama i kona ikehu a hiki i ka wā e pono ai.

ʻElua ʻāpana o nā molekala photoswitch: kahi ʻāpana omo mālamalama a me kahi ʻāpana mālama. Ke hōʻike ʻia i ka lā, omo nā molekala i ka ikehu a mālama iā ia i kahi ʻano paʻa. Ke pono ka ikehu i mālama ʻia, hiki ke hoʻāla ʻia nā molekala e hoʻokuʻu i ka ikehu ma ke ʻano o ka wela a i ʻole ka mālamalama.

He nui loa nā noi kūpono no kēia holomua. No ka laʻana, hiki iā ia ke ʻae i nā kumu ikehu hou e like me ka mana o ka lā a me ka makani e hoʻohana pono ʻia, ʻoiai ke ʻālohilohi ʻole ka lā a i ʻole ka makani ʻole. Hiki iā ia ke hiki ke mālama i ka ikehu keu i hana ʻia i nā manawa haʻahaʻa o ke koi a laila hoʻokuʻu iā ia i nā wā kiʻekiʻe o ke koi, e hōʻemi ana i ka pono no nā hale hana mana wahie fossil pipiʻi a hōʻino i ke kaiapuni.

Ua hauʻoli nā kānaka noiʻi ma hope o kēia holomua i kona hopena i ka ʻoihana ikehu. "Hiki i kēia ke lilo i mea hoʻololi pāʻani," wahi a kekahi o nā kānaka noiʻi alakaʻi, ʻo Polofesa Omar Yaghi. "Hiki iā ia ke hoʻolilo i ka ikehu hou i mea kūpono a kūpono hoʻi i ke kumukūʻai, a kōkua iā mākou e neʻe i kahi wā e hiki mai ana e hoʻomau."

ʻOiaʻiʻo, nui ka hana e hana ʻia ma mua o ka hoʻokō nui ʻia ʻana o kēia ʻenehana. Ke hana nei nā mea noiʻi i ka hoʻomaikaʻi ʻana i ka pono o nā molekala photoswitch, a me ka ʻimi ʻana i nā ala e hoʻonui ai i ka hana ʻana. Akā inā holomua lākou, hiki i kēia ke lilo i wahi huli nui i ke kaua ʻana i ka loli o ke aniau a me kā mākou hoʻololi ʻana i kahi wā e hiki mai ana maʻemaʻe a hoʻomau.

I ka hopena, ʻo ka hoʻomohala ʻana o nā molekala photoswitch he holomua nui ia i ka ʻoihana ikehu. Ma ka hāʻawi ʻana i kahi ala hou e mālama ai i ka ikehu hou, hiki i kēia ʻenehana ke kōkua iā mākou e neʻe aku mai ko mākou hilinaʻi ʻana i nā wahie fossil a i kahi wā e hiki mai ana. ʻOiai he nui nā hana e hana ʻia, ʻo kēia holomua he ʻanuʻu hoihoi i mua i kā mākou ʻimi ʻana i ka ikehu maʻemaʻe a ʻōmaʻomaʻo.
