Haugoni kurara usiku? Kupomera majini ako

Iwe nhema muka usiku hwose, vachitarisira kuzorora kanenge maawa mashoma? Muri vaneta rechikepe uye akatendeukira pamubhedha, kuverenga gwai vanopfuura zana, asi havana kukwanisa kupinda mashiripiti nyika kurara? Zvakaratidza, chinetso kubatwa nehope anogona -bereka kwatiri kubva kuvabereki, sezvo vari encoded mu majini edu.

Common zvinokonzera hope

Sezvineiwo, hatisi kutaura pamusoro nguva idzodzo kana iwe unogona tisarare kubvira nguva nenguva, somuenzaniso nokuti kushushikana chinhu. Izvi zvinoreva kuti dzakazara kushaya hope, izvo zvinogona kutora inoverengeka kana kunyange kwemakore. Zvinogona kuitika kuti nezvikonzero zvakasiyana-siyana, kusanganisira mwoyo, murombo mamiriro nokuti hope, panyama nepfungwa zvokurwara, uyewo nemishonga vamwe mishonga.

Kare, masayendisiti vaifungidzira kuvapo masero zvezvinangwa kuti ape vamwe vanhu vafanorongerwa kuti hope, asi kudzidza itsva yakabudiswa muna Nature genetics, anotipa zvakawanda chivimbo Kururama pfungwa iyi kupfuura kare.

Chii mhosva genetics?

Boka masayendisiti kubva University of Amsterdam akawana nomwe "majini ngozi" vane mharidzo, iro raiva 113 006 vanhu. majini izvi zvinowedzera mukana hope, kana zvichienzaniswa vatakuri vaya vanhu vanodaro havana. Zvisinei, havana hadzishandi kukonzera kushaya hope. Chokwadi kuti majini njodzi isina chokuita zvakananga maumbirwo hope, asi kuvapo kwavo vanhu genome pave divi mugumisiro rinoita kukonzera matambudziko hope.

Chinangwa chikuru chemusha majini izvi - verenga DNA uye RNA kuti makopi, uye anobvumira sero kubereka zvichikurukura mamorekuru, kuitira kuti kukurukura zvakavapoteredza. Nokuda kwechimwewo chikonzero, kuvapo kwavo sokuti Nenyaya Iyi pamwe mikana yakawanda ezvinhu anoverengeka, kusanganisira kuzvidya zvirwere, kuora mwoyo, neuroticism, pane kushayikwa zvakanaka, zvinetso zvedzidzo uye kushaya hope.

Kutsvakurudza chikwata akacherechedza kuti rimwe majini izvi ndiwo mukana - MEIS1 - awanikwa vanenge kudzikama makumbo chirwere uye nguva nenguva kufamba mu hope. zviitiko izvi vanoonekwa ne nguva dziri kure zvenyama kufamba, apo hope, Chokwadi, akasiyana kuparadza pesvedzero mupfungwa.

Chinoshamisa, mukana majini uye akabatanidza kushaya hope vakanga zvakawanda zvakajairika nevanhu (33 muzana mharidzo) pane vakadzi (24 muzana mharidzo). Pari, musiyano uyu haana tsananguro.

"Izvi zvinoratidza kuti hope mu varume nevakadzi vanogona kukonzera zvakasiyana zvipenyu zvenhengo" - akati kudzidza munyori Danielle Posthuma, purofesa Statistical genetics paYunivhesiti Amsterdam.

chakakomba ezvinhu

Saka, isu vachine zvakawanda zvokudzidza pamusoro hope, asi kudzidza iyi kunoratidza kuti majini nhaka kubva vabereki, kutamba yakakura basa pane kare akafunga. Sezvaunogona kuona, vamwe vanhu vane hope - haisi chete mupfungwa ezvinhu.

Chero zvazvingava, kushaya hope kunounza zvikuru mupfungwa uye mumuviri mutero. Kana zvava zvakakomba zvakakwana, haufaniri kuvimba vavete mapiritsi. Chiremba wako kuti actionable audzwa.
