Ii-microplastics zinokuphazamisa kakhulu ukusebenza kwee-phagocytes esibindini, ubuncinci kwiimpuku. Isiphumo kukuphazamiseka kokusebenza kwe-metabolic yesitho kunye nokugcinwa kwamafutha okwandisiweyo. Ezi ziziphumo eziphambili zophando lwaseJamani nase-Austria olukhokelwa yiYunivesithi yaseBonn, olupapashwe kwijenali i-Nature Metabolism. Ii-Phagocytes, ezaziwa ngokwesayensi njengee-macrophages, luhlobo olukhethekileyo lomhlophe... Funda ngokugqithisileyo »

Ukuvuselelwa kweplastiki yePET kwi-levodopa nge-microbial: ukwenziwa kwesiyobisi sikaParkinson ngokuzinzileyo

Abaphandi baphuhlise inkqubo ye-biotechnology eguqula inkunkuma yeplastiki ye-polyethylene terephthalate (PET) ibe yi-levodopa (L-DOPA) - iyeza eliphambili lokunyanga isifo sikaParkinson. Le ndlela isebenzisa i-Escherichia coli eguqulwe ngokwemfuza kwaye ifumana isivuno esiphezulu phantsi kweemeko ezithambileyo nezimanzi. Iqela, elikhokelwa nguBenjamin Royer kunye noStephen Wallace, lakha indlela ye-biosynthetic enamanyathelo amane eguqula i-terephthalic acid (TPA) - i-monomer ephambili ye-PET - nge...

Amahlathi angcoliswa ziiplastiki ezincinci ezingena emhlabeni zisuka emoyeni. Oku kuboniswe kuphando olutsha olwenziwe yi-TU Darmstadt, olupapashwe kwi-Nature Communications Earth & Environment. Okokuqala ngqa, kubonisa ukuba umhlaba wehlathi ugcina iiplastiki ezincinci kunye nezincinci, ezifana neelwandle okanye umhlaba wezolimo. Izazinzulu zejografi zifumanise ukuba amasuntswana eplastiki ngokuyintloko angena emahlathini ngomoya. Aqokelelana... Funda ngokugqithisileyo »

Abaphandi kwiYunivesithi yaseLeibniz eHannover baphuhlise i-hydrogel entsha efunxa kwaye yonakalise ii-microplastics emanzini ngokuzimela. Ii-Microplastics, ezingcolisa ulwandle, amachibi, kunye nemilambo, zibangela ukudumba kunye noxinzelelo lwe-oxidative kwizinto eziphilayo. Iinkqubo zesihluzo eziqhelekileyo zokususa kwazo zibiza kakhulu kwaye zisebenzisa amandla amaninzi. Le nto intsha, i-hydrogel ye-thermoresponsive ene-organosilicate particles ene-porous kunye ne-photocatalyst, isebenza ngokuzimeleyo. Itshona emanzini angcolileyo... Funda ngokugqithisileyo »

I-Transpolar Drift, umsinga omkhulu wolwandle, yindlela ebalulekileyo yokuthutha amanzi acocekileyo kunye nezinto zomhlaba kwi-Arctic Ocean. Lo msinga womphezulu awupheleli nje ekubumbeni iindawo eziphilayo ze-polar kodwa ukwachaphazela nokujikeleza kolwandle lwehlabathi. Iqela lophando lwamazwe ngamazwe elikhokelwa yiYunivesithi yaseBristol, kunye namaqabane aphesheya kuquka iKiel University (CAU) kunye neAlfred Wegener Institute, iHelmholtz Centre for Polar and Marine Research, ngoku ine… Funda ngokugqithisileyo »
