Umntu osisidenge unobomi obufutshane

Ubudenge bubonakala buneenkalo ezintle kananjalo.Emva kombuzo, yintoni eyandisa ubomi bomntu, ubukrelekrele okanye ubudenge?Okrelekrele usenokubonakala eselula, njengoko ekhathazwa yimibuzo ehlala ihleli yaye ecinga phantse ngayo yonke into.
Kodwa uphando olutsha lubonisa ukuba abantu abahlakaniphile baphila ixesha elide, ngenxa yento ebizwa ngokuba "yimfuza yengqondo" elawula ukuguga.

Kwesi sikhokelo, izazinzulu ziye zachonga ngaphezu kwama-500 ama-fairies anxulumene nabantu abanengqondo enkulu, ephindwe ka-10 ngaphezu kokucinga kwangaphambili.
Uphando lwangaphambili lucebisa ukuba iijini zobukrelekrele zonyusa ukuhanjiswa komqondiso phakathi kwemimandla eyahlukeneyo yobuchopho, kunye nokukhusela ngokuchasene nokudodobala kwengqondo kunye nokufa kwangaphambi kwexesha.

Umbhali wesifundo uGqr David Hill, weYunivesithi yase-Edinburgh, wathi: 'Ubulumko buthathwa njengophawu lwemfuza, kunye noqikelelo olubonisa ukuba phakathi kwe-50 kunye ne-80 yeepesenti yeeyantlukwano zobukrelekrele kunokuchazwa ngemfuza.
"Kuye kwaphawulwa ukuba abantu abanomgangatho ophezulu wokusebenza kwengqondo banempilo engcono ngokomzimba nangokwengqondo, kwaye banethuba lobomi obude," uyongezelela.
Isifo se-Alzheimer's, eyona ndlela ixhaphakileyo yesifo sengqondo esiyingozi, sichaphazela abantu abangama-850 e-UK.
Iziphumo zophando lwakutsha nje zibonisa ukuba kukho iijini ezingama-538 ezidlala indima kubukrelekrele, ngelixa imimandla ye-187 ye-genome yomntu inxulumene nobuchule bokucinga.
"Uphononongo lwethu lubonise ukudibanisa kwenani elikhulu leemfuza ezinobulumko bomntu," kusho uGqr Hill.

Ekuqaleni kwalo nyaka, uhlolisiso lwabantu abangaphezu kwama-78000 52 lubonise ukuba yimizila yemfuza engama-XNUMX kuphela enxulunyaniswa nobukrelekrele.
Uphononongo lubonise ukuba abantu ababonisa ezi genes ebuntwaneni akufane kwenzeke ukuba babe nesifo i-Alzheimer's, ukudakumba, i-schizophrenia kunye nokutyeba kakhulu kamva ebomini.
Kuphononongo lwakutsha nje, abaphandi bahlalutya ukuguquguquka kofuzo kwabantu abangaphezu kwe-240 emhlabeni jikelele, ukufikelela kwiziphumo zamva nje.
Iingcali zenzululwazi zicebisa izisombululo ezinceda ekuphuhliseni ubukrelekrele bomntu, njengemidlalo, kunye nokudansa, okusebenza ngakumbi kule nto, ngakumbi ngomculo, njengoko iphuhlisa ukumkanikazi woxinaniso.
