Kungakhathaliseki ukuthi kungumuntu, isilwane, noma ulwelwe – zonke izinto eziphilayo zilandela isigqi sangaphakathi esiqondiswe ekukhanyeni. Ukuthi amaprotheni athile alawula kanjani lesi sigqi sasemini nobusuku kwakungakacaci ngaphambili. Ithimba locwaningo lwamazwe ngamazwe eliholwa nguSolwazi uDkt. Lars-Oliver Essen wasePhilipps University of Marburg, kanye nokubamba iqhaza kweNational Taiwan University (NTU), manje selithole okokuqala ukuthi lokho kubizwa kanjani… Funda kabanzi »

Ukungcola kokukhanya, okukhanyisa isibhakabhaka sasebusuku njengokukhanya kwesibhakabhaka, kukhuthaza ukukhula kwe-algae eluhlaza okwesibhakabhaka (i-cyanobacteria) futhi kukhuthaze ukujikeleza kwezakhamzimba emachibini. Lokhu kuboniswe ocwaningweni lwakamuva lwe-Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB), okuyingxenye yokuhlolwa okukhulu kakhulu kwensimu kuze kube manje ngemiphumela yokungcola kokukhanya emachibini. Wonke umuntu ujwayelene nakho: i-dome yokukhanya, ebonakala ngokucacile kude, ekhombisa lapho amadolobha ekhanya khona ebusuku... Funda kabanzi »

Ukukhanyisa ebusuku kubangela izinguquko ezakhini zofuzo ezingaphezu kuka-1.500 ohlotsheni lomiyane obaluleke kakhulu endalweni.

Ucwaningo lwamuva nje lubhala ngemiphumela ephawulekayo yokukhanya kwasebusuku okwenziwe ezinambuzaneni. Abacwaningi bahlole uhlobo lwe-midge i-Chironomus riparius bathola ukuthi ukungcola kokukhanya kubangela izinguquko ezinkulu ezizakhini zofuzo ezingu-1.564 zezibungu. Imiphumela iyesabisa: ukuthuthuka okulibazisekile, ukwanda kokucindezeleka kwe-oxidative, kanye nokwehla okukhulu kwamandla okuzala. Kumagazini i-"Environmental Pollution," abacwaningi baxwayisa ngemiphumela ebanzi yezemvelo... Funda kabanzi »
