Abantu abaningi bathokozela okutholwe yisayensi futhi namuhla sekuyisikhathi sokukhuluma nge izihlahla, imijikelezo yempilo yazo kanye nokugayeka komzimba.
Iqembu lososayensi abavela e-Austria, eFinland naseHungary laqala ukutadisha i- ukuziphatha kwesihlahla futhi bathola ukuthi bahamba ebusuku ngaleyo ndlela bezivumelanisa nalawo mahora osuku.
I-hypothesis
Njengazo zonke izinto eziphilayo, izitshalo nazo zivumelana nomehluko phakathi kwemini nobusukuhey ngakho zamukele isigqi esihlukile sempilo ngokwesikhathi sosukuuku. Ososayensi abaningi baye bafunda isimila sokuziphatha kuwo wonke amahora angama-24 ngosuku kufanele athole izinguquko ezikhiqizwa phakathi kwemini nobusuku.
Yize kuze kube manje bekutholakele lokho izitshalo zilala ebusuku zikhiqiza ukunyakaza okungafani kobusuku emaqabungeni naseziqu zombili, bekungaziwa noma lokhu kwenzeke ngezihlahla.
Kepha imfihlakalo igcine yembuliwe njengoba leli qembu lososayensi lithole ukuthi izihlahla nazo zihamba ebusuku, ukusebenzisa indlela yokulala efana naleyo yezitshalo. Ngosizo lwe-laser, iqembu lochwepheshe liqopha ukunyakaza okungafika kuma-intshi amane ezihlahleni eziphakeme ngamamitha amahlanu. Bakuphetha kanjalo izihlahla zincike ebusuku ngaleyo ndlela kuguqulwa ukuma kwamaqabunga awo namagatsha. Ngenkathi bethi izinguquko azizinkulu kakhulu, bathole nokuthi zihlelekile.
Ucwaningo
Ngesikhathi sophenyo kubhekwe ukuthi amaqabunga namagatsha awe kancane kancane, afike endaweni ephansi amahora ambalwa ngaphambi kokuphuma kwelanga abuye abuyele endaweni yawo yasekuqaleni ekuseni. Lokhu kukhuluma ngakho ukunyakaza kwezitshalo Lokho, njengoba u-András Zlinszky, weSikhungo Sokucwaninga Kwemvelo kweHungary Academy of Sciences kuyakuqinisekisa. "Kusondelene kakhulu nokulinganisela kwamanzi kumaseli ngamanye, okuthinteka ukutholakala kokukhanya nge-photosynthesis."
Ukuloba i- ukuhamba kwezihlahla, ososayensi basebenzise uhlelo lokuskena i-laser, olwaluklanywa ngokuzenzakalela kusetshenziswa amafu e-scan point. Ngenxa yale ndlela, sikwazi ukuqonda indlela yokulala yezitshalo. Esinyathelweni esilandelayo, abacwaningi bazosebenzisa amafu wephuzu lokuskena ukubhekela ukusetshenziswa kwamanzi emini nasebusuku nokuthi kukhona umehluko phakathi kwale mijikelezo emibili. Lokhu kuzovumela ukuqonda kangcono ithonya lezihlahla esimweni sezulu sendawo kanye nesifunda.
