Kule veki (7.4-7.8, ezifanayo ngezantsi), ukukhanya kunye nokukhanya okunqabileyo kwimveliso enqabileyo kwimarike yomhlaba enqabileyo kubonakalise imeko esezantsi, kunye nenqanaba lokukhanya elinqabileyo lalikhawuleza. Inokwenzeka yoqoqosho oluphambili eYurophu nase-United States eliwela kwi-stenation yoqoqosho kwisiqingatha sesibini sonyaka icacile, kwaye ii-odolo zokuthumela ngaphandle ziye zafumana imiqondiso yokuchasana. Nangona ukubonelelwa okungaphantsi kuye kuncitshisiwe, kuthelekiswa nenqanaba lezinto ezenza buthathaka lemfuno, kubonakala ngathi kusekho intsalela. I-phessimism iyonke inyuka inyuka le veki, kwaye ukukhanya kunye nehlabathi elinqabileyo linqabile kwityala elibonakalayo elibonakalayo.
Kule veki, iimveliso zokuzizungu kwe-rasehedmium kunye ne-neodimium ziqhubekile nemeko yeveki ephelileyo. Ukurhoxiswa kwemikhosi eyahlukeneyo, imfuno kunye nolindelo olubuthathaka, luqhutywa yingcinezelo yokubhida, isantya sohlengahlengiso esiphantsi samashishini aphezulu akhawuleziwe kakhulu. Inyathelo lemakethi yayingumthengi, kwaye ixabiso lentengiselwano libetha eliphantsi eliphindiweyo ngenxa yempembelelo yengqondo ye "thenga kodwa ungayithengi".
Ichatshazelwe yi-rasehedymuum kunye ne-neodimium, imfuno yezinye iimveliso zomhlaba ezinqabileyo zomhlaba nazo zikwabanda, kwaye iimveliso zeGadoliium zinciphile kancinane. Nangona kunjalo, ngenxa yokwehla kancinci kwexabiso lemigodi yomhlaba onqabileyo, iidysprosium zemveliso zizinziswe ekupheleni kweveki ephelileyo, kwaye inesifo sokwehla kancinci ngenxa yempembelelo yemozulu iyonke. I-dysprosium oxide iwile nge-8.3% ukusukela ngo-Epreli. Ngokwahlukileyo koko, ixabiso eliphakamileyo lembali lemveliso le-terbium ligcinwe kangangesiqingatha sonyaka, kwaye ukusetyenziswa kwawo onke amaqela kwikhonkco lemizi-mveliso kuncitshisiwe kuloyiko lwamaxabiso aphezulu kunye nethandabuza. Nangona kunjalo, ukuthetha, imfuno ye-terbium kumaxesha akutshanje iphucule xa ithelekiswa nexesha elidlulileyo. Ivolumu ye-bulk ye-Bulk kwimarike incinci kwaye kukho amaxabiso aphezulu, ke ubuntununtunu kwiindaba zentengiso zibuthathaka kancinci. Kwi-terbium kwixabiso langoku, kungcono ukuthi lulawulo lwevolumu epheleleyo kunokuba luyele i-terbium, ngoko kwandise uxinzelelo lwe-terygo lemizi-mveliso iphantsi kakhulu kune-dysprosium.
Ukusuka kwimbono yeMacro yangoku, iDollar yase-US yaqhekeza kwaye inyuke. Ezinye iindaba zathi yayikukunciphisa ukungabikho kwe-United States, urhulumente wase-US wayelindeleke ukuba aphumle kwi ntlawulo kwi-China, kwaye ubhubhane kwiindawo ezininzi zehlabathi lubuya umva. Ukongeza, ubhubhane kwiindawo ezahlukeneyo zelo lizwe lwaphindaphindwa, ke imeko iyonke yayiyinto engenathemba. Ukusuka kwimbono yeziseko ezikhoyo ngoku, ukwehla ngokukhawuleza kwamaxabiso emhlabeni okunene kuye kwabangela uxinzelelo lokuthengwa kwempahla esezantsi. Okwangoku, izalathiso zomhlaba ezinqabileyo zekhaya azilindelanga ukuba zande. Uninzi lwamashishini okuvelisa amakhaya aya kugqiba kakhulu uninzi lwezalathiso kulo nyaka. Imiyalelo yexesha elide yoku-odola iqinisekisa imfuno ethile esezantsi, kwaye inani elincinci lemfuno lingakhokelela ekubhideni kakhulu.
