Kuyathakazelisa isibalo seziphakamiso eziza ukukhuthaza ukusebenza kwezemidlalo. Kuze kube yiminyaka embalwa edlule, labo ababezifela ngezemidlalo bagqoka noma yiliphi ihembe likakotini futhi baqeqeshe noma kunjalo. Ngokuthuthuka kwesayensi, kutholwa izinto ezintsha eziqinisekisa ukuthuthuka komsubathi. Kulo mcimbi sizokutshela ngombono odalwe onjiniyela baseNyuvesi yaseCalifornia e-Irvine, abagqugquzelwe ukwakheka kwesikhumba se-squid.
Ukudalwa kwembulwe ngaphakathi Ucwaningo eshicilelwe ku-Nature Communications. Sikutshela konke okuhlobene nale ndwangu entsha eguquguqukayo yesimanje, ekuvumela ukuthi ulawule izinga lokushisa lakho.
Sisebenza kanjani isikhumba se-squid?
Kuyathakazelisa ukuthi indwangu yezemidlalo ilingisa izici zemvelo zesikhumba se-squid ukuze zivumelane nendawo yayo. Ukuze benze lokhu, abacwaningi bathatha amasampula omklamo ezinhlobo eziningana ze-squid, i-octopus ne-cuttlefish ezisebenzisa isikhumba esiguquguqukayo nesiguquguqukayo ukuze siphile emanzini. Ikhono lama-cephalopod lokuzifihla ngokushintsha umbala ngokushesha libangelwa amangqamuzana esikhumba (ama-chromatophores) angashintsha ngokushesha.
"Izingubo zokulala ze-Ultralight sekungamashumi eminyaka zikhona - abagijimi bemarathon bazigoqa ngazo ukuze bavimbele ukulahlekelwa ukushisa komzimba ngemva kokugijima - kodwa i-drawback enkulu ukuthi impahla imile.”, kusho umbhali ohlanganyele womsebenzi, u-Alon Gorodetsky. Nokho, ithimba lonjiniyela likwazile ukwakha “inguqulo enezici ezilungisekayo ukuze inani lokushisa elibanjiwe noma elikhishiwe likwazi ukulawulwa".
Umqondo uhumushe kanjani kwezemidlalo?
Ngokusho kukaGorodetsky, le nto entsha inezicelo eziningi, ikakhulukazi ezingutsheni zendwangu. Bangase bakwazi ukulungisa imingcele yomsebenzisi ngamunye, ukuze abagijimi bazizwe bekhululekile ukuqeqeshwa endaweni evaliwe noma evaliwe. Ngaphezu kwalokho, lokhu kungadala ukonga okungaba ngu-30 kuya ku-40% ekusetshenzisweni kwamandla okushisa nomoya, ngokusho komlobi wocwaningo.
Endabeni yabagijimi bemarathon, bangachaza izinga elifiswayo lokunethezeka okushisayo kwengubo ngayinye, bathuthukise ukusebenza ngesikhathi somjaho kanye nokululama ekugcineni. Ngokufanayo, isisindo esilula, izindleko eziphansi zokukhiqiza kanye nokukhululeka kuyagqama, kanye nokuqina kwempahla. «Iyakwazi ukwelula futhi ibuyele esimweni sayo sasekuqaleni izikhathi eziyizinkulungwane.".
