Amanye amaxoxo akhanya lapho kuhwalala, esebenzisa i-fluorescent compound, ososayensi bathi
Ngo-2017, ososayensi bamemezela isimangaliso semvelo, amanye amaxoxo akhanya ngokuhlwa, esebenzisa i-fluorescent compound esingakaze siyibone ngaphambili emvelweni.
Ngaleso sikhathi, kwakungaziwa ukuthi zingaki izinhlobo zamasele ezingakhipha le fluorescence.
Ucwaningo lwezinhlobo ezingu-151 zamasele aseNingizimu Melika lubonisa izinga le-fluorescence yohlobo ngalunye. Idatha evela ocwaningweni iphakamisa ukuthi i-fluorescence iboshelwe embonweni wamaxoxo.
Ngokusho kososayensi, ukuphuma kokukhanya kuthinta indlela amaxoxo abonisana ngayo. Bakholelwa ukuthi i-fluorescence ixosha izilwane ezizingelayo.
“Ngocwaningo olwenziwe eNingizimu Melika, sathola futhi sabhala amaphethini e-biofluorescence ezilwaneni ezihlala emanzini ashisayo,” kubhala isazi sezinto eziphilayo saseFlorida State University u-Courtney Witcher.
“Izinto eziningi ezilwaneni ziyakhazimula, kodwa isizathu asibonakali ngaso sonke isikhathi,” kuphawula ososayensi.
I-Fluorescence iwuhlobo lokukhanya oludalwa lapho ukukhanya kumuncwa futhi kukhishwa kabusha ngobude obuhlukile, futhi kubonakala ezinhlobonhlobo eziningi, okuhlanganisa oshaka, ama-chameleon namasalamanders. Amathambo abuye abe ne-fluoresce, ososayensi bayachaza.
I-biofluorescence ekhiqizwa esikhumbeni samaxoxo ihlukile kune-fluorescence yezinye izilwane ezikhanyayo.
Ukukhanya okuluhlaza okwesibhakabhaka, okuseduze kakhulu nokuhwalala kwemvelo koMhlaba, kukhiqiza i-fluorescence enamandla kakhulu, futhi i-fluorescence ngokwayo ibonakala ngokuyinhloko eziqongweni ezimbili ezihlukene zokukhanya okubonakalayo - okuluhlaza okusawolintshi, kusho ososayensi.
Amaxoxo amaningi ane-crepuscular - okungukuthi, asebenza ngokuhlwa. Kwezinye izinhlobo zezilwane, amehlo azo aklanyelwe ukusebenza kangcono kulokhu kukhanya, abuswa ama-photoreceptor amise okwenduku azwelayo kokuluhlaza nokuluhlaza, kubhala i-Science Alert.
Ukukhanya okuluhlaza kwamaxoxo kukhanya kakhulu emini, ososayensi bayachaza. Izingxenye zomzimba ezikhazimulayo yilezo ezithinteka kakhulu ekuxhumaneni kwezilwane, umphimbo nomhlane. Lokhu kusikisela ukuthi i-biofluorescence iyingxenye yamathuluzi okuxhumana amaxoxo.
