Isidalwa esisheshayo emhlabeni: ososayensi bayathola

U-2018 unyaka ugcwele lezimanga emkhakheni wokutholwa kwesayensi. Ngemuva kokudluliselwa ngempumelelo kwekhanda nokuhlukaniswa okuyingxenye kofuzo lomuntu, ososayensi bakwazile ukuthola isidalwa esisheshayo emhlabeni.

Umqondo "wesidalwa" uthinta umhlaba wezilwane ezingenamsoco nezakhamuzi zomhlaba ezingenakubalwa

Isidalwa esisheshayo emhlabeni

Ososayensi eGeorgia Institute of Technology, eseMelika, bakwazile ukukala ijubane lokuhamba kwabantu abahlala emanzini amasha. I-Spirostomum ambiguum - Isidalwa esinjengesika-unicellular esifana ne-4 mm sihamba emanzini ngosizo lokuzitika komzimba. I-Cilia etholakala emzimbeni ozungeza uzungu isiza umzimba ukuthuthukisa isivinini.

Amakhilomitha we-724 ngehora - isitho se-unicellular Spirostomum ambiguum setha irekhodi elinjalo lesivinini

Isidalwa esisheshayo kule planethi sihehe abacwaningi nabezempi. Ngemuva kwakho konke, ngemuva kokuthola umgomo wokuhambisa umzimba emanzini, uzokwazi ukukhiqiza kabusha lo mshini kumarobhothi noma okokusebenza kwempi. Kwethenjwa ukuthi abaseMelika basebenzise ubuchwepheshe ngezinhloso zokuthula.

Kwezindaba, izifundiswa zase-Asia ziveza ukuthi ukwenza amaphupho ngamathuba kunzima. Ngemuva kwakho konke, akukaze kwenzeke ukwenza i-analogue yobuchopho bomuntu noma ezinye izitho ezibalulekile.
