Okuqukethwe
Nsuku zonke sifunda inqwaba yezinto zesayensi zakwamanye amazwe ukuze sikhethe ezithakazelisa kakhulu nezingase zibe usizo kubafundi baseRussia. Namuhla siqoqa embhalweni owodwa isifinyezo esifushane sezindaba ezinhlanu ezibalulekile zenyanga edlule.
1. Uzwela olumnyama lukhona: luyini?
Sekuyisikhathi eside kwaziwa ukuthi "i-triad emnyama" yezimpawu zobuntu ezingezinhle ihlanganisa i-narcissism, i-Machiavellianism, kanye ne-psychopathy. Izazi zokusebenza kwengqondo ezivela eNyuvesi yaseNottingham Trent (UK) bathole ukuthi uhlu lunganwetshwa ngalokho okubizwa ngokuthi “uzwela olumnyama”: abantu abanjalo bangaba yingozi nakakhulu kwabanye kunalabo abangenalo uzwela oluncane noma abangenalo nhlobo. Ngubani lo? Labo abajabulela ukulimaza noma ukuxhaphaza abantu ngokufaka umuzwa wecala, usongo lokucwaswa (ukwaliwa emphakathini), namahlaya ahlekisayo.
2. Imuphi umbuzo okuvumela ukuthi uhlole ubungozi bokuhlukana kombhangqwana?
Uchwepheshe wemibhangqwana u-Elizabeth Earnshaw, eminyakeni yokuhlangenwe nakho kwakhe, uye wathola umbuzo okhuluma kakhulu ngenhlalakahle nokukhuthazela kombhangqwana kunanoma yimaphi amanye amaqiniso. Lo mbuzo uthi "Nahlangana kanjani?". Ngokombono ka-Earnshaw, uma umbhangqwana ugcina ikhono lokubuka isikhathi esidlule esivamile ngemfudumalo nesisa, lokhu kuwuphawu oluhle. Futhi uma ngamunye wabo okwedlule kupendwe kuphela ngamathoni angalungile, ngakho-ke, cishe, izinkinga ebuhlotsheni zibucayi kangangokuthi kunamathuba amaningi okuhlukana.
3. Imisebenzi Eyisicefe Kakhulu Eveziwe
Ososayensi baseNyuvesi yase-Essex, ngokusekelwe ocwaningweni olukhulu, bahlanganisa uhlu lwezici ezibonisa isithukuthezi somuntu, futhi bahlobanisa lolu hlu nobungcweti. Baqhamuke nohlu olufushane lwemisebenzi evame ukufundwa njengokuyisicefe: ukuhlaziywa kwedatha; ukubalwa kwezimali; intela/umshwalense; ukubhanga; ukuhlanza (ukuhlanza). Lolu cwaningo luhlekisa kakhulu kunokuba lubucayi, ngoba ngamunye wethu angakhumbula intokazi yokuhlanza emangalisayo okumnandi ukuxoxa nayo ekuseni, noma ibhange elihamba phambili.
4. Imiphumela ye-covid ethambile ebuchosheni ibibucayi kakhulu kunalokho ebesikucabanga
Indatshana yashicilelwa kujenali yesayensi egunyaziwe i-Nature, eyahlaziya imiphumela ye-covid ethambile ebuchosheni bomuntu. Kwavela ukuthi ngisho nefomu le-asymptomatic lesifo lithinta amakhono okuqonda - ukulahlekelwa kobuhlakani kulinganiselwa kumaphuzu angu-3-7 esikalini se-IQ yakudala. Kukude njalo ukuthi lokho okulahlekile kungabuyiselwa ngokushesha futhi kalula, nakuba ukuzivocavoca okuthile (isibonelo, ukuqoqa ama-puzzle) kungaba usizo.
5. Ukufunda ezikrinini ze-smartphone akukaphephile.
Izincwadi zamaphepha, ososayensi abavela eSikoleni Sezokwelapha sase-Showa University (eJapane), bafakazele ukuthi zigaywe kangcono kunombhalo osesikrinini, futhi zivusa umsebenzi omncane ku-prefrontal cortex. Uma konke kucacile ngomzuzu wokuqala, uthini owesibili? Futhi iqiniso lokuthi umuntu one-prefrontal cortex esebenza "ngesivinini esikhulu" uthatha ukuphefumula okuncane futhi akagcwalisi ubuchopho nge-oxygen kahle. Ngakho-ke ubuhlungu bekhanda obujwayelekile kulabo abaskrola ezinkundleni zokuxhumana amahora amaningi futhi bafunde izindaba ezivela kusikrini seselula.
