Yize kunocwaningo oluningi ngokwengeziwe ngezimpawu zomzimba nezengqondo zenja, iqiniso ukuthi zimbalwa kakhulu izifundo eziye zenziwa indlela abayisebenzisayo ukuphuza. Muva nje, ucwaningo olwenziwe yiVirginia State University (olwaziwa ngeVirginia Tech) lungene kulolu daba, lwathola iziphetho ezithakazelisa kakhulu.
Kule phrojekthi, ososayensi bahlaziye indlela yokuphuza Izinja eziyi-19 ezinobukhulu obuhlukahlukene nezinhlobo ezahlukahlukene. Ezingu-XNUMX zazo zathwetshulwa emizini yazo endaweni yaseBlacksburg (eVirginia), kwathi eziyisithupha ezisele zathwetshelwa enyuvesi. Ngemifanekiso etholakele, ososayensi bacwaningisise ngokunyakaza okwenziwa yizinja lapho ziletha amanzi emlonyeni wazo.
Babonile ukuthi, ngemuva kokufaka ulimi lwabo emanzini, baluphindisela ngokushesha phezulu, bakha impophoma encane beqonde emlonyeni wabo. Olunye uketshezi luhlala engxenyeni engezansi yolimi, ngalo bakha “isipuni” esincane. Kepha ukubamba amanzi avuzayo, izinja yenza ukunyakaza "kokuluma" phansi, bese uvula umlomo futhi bese uphinda inqubo.
«Okokuqala, izinja zenza i- ukunyakaza okushesha kakhulu kolimi ukwakha impophoma; bese-ke, igobela ngaphakathi ukwandisa ukungena kwamanzi okuwa; ekugcineni, izinja ziyaluma manje nje lapho kwenzeka le mpophoma ” Le yindlela uSungwan Jung, uprofesa ohlangene wezobunjiniyela bezinto eziphilayo kanye nemishini eVirgina Tech nomxhumanisi wale phrojekthi.
Futhi ngukuthi ngokungabi namandla okuncela ezihlathini njengabantu, izinja kufanele sebenzisa ulimi ukumunca uketshezi. Kwenzeka okufanayo nasemakati, yize lawo akamuva ekwazi ukunamathela amanzi ezilimini zawo, angawagcini ngokuphelele. "Ngaphambi kokwenza lolu cwaningo, sasikholelwa ukuthi bobabili babephuza ngendlela efanayo," kuvuma uJung.
