Anyamata olimba m'mphepete mwa danga

Malinga ndi kufufuza kochitidwa ndi akatswiri a sayansi ya tizilombo tosaoneka ndi maso a pa American University of Maryland, pakati pa ena, stratosphere muli tizilombo toopsa toopsa totha kupirira kuzizira koopsa ndi kuphulika kwa ultraviolet ndipo ndi malire akutali kwambiri a zamoyo zapadziko lapansi. Asayansi akufuna kupanga "Atlas of Stratospheric Microbes" yomwe ingatchule tizilombo tomwe timakhala m'mwamba.

Maphunziro a tizilombo tating'onoting'ono tating'onoting'ono tamlengalenga akhala akuchitika kuyambira m'ma 30. Mmodzi wa apainiya awo anali wotchuka Charles Lindberghamene, pamodzi ndi mkazi wake, adasanthula zitsanzo za mumlengalenga. Gulu lawo lidapeza mwa iwo, mwa ena, spores za bowa ndi mbewu za mungu.

M'zaka za m'ma 70, maphunziro achilengedwe a stratosphere adachitika, makamaka ku Ulaya ndi Soviet Union. Atmospheric biology ikuphunziridwa pano, kuphatikiza kudzera mu projekiti ya NASA yotchedwa PAMWAMBA (). Monga momwe asayansi amanenera, mikhalidwe yoipitsitsa padziko lapansi ndi yofanana ndi yomwe ili mumlengalenga wa Martian, kotero kuphunzira za moyo wa stratospheric kungathandize kuzindikira "alendo" osiyanasiyana kunja kwa dziko lathu lapansi.

- - adatero poyankhulana ndi "Astrobiology Magazine" Shiladitya DasSarma, katswiri wa tizilombo toyambitsa matenda ku yunivesite ya Maryland. -.

Tsoka ilo, palibe mapulogalamu ambiri ofufuza operekedwa ku zamoyo zam'mlengalenga. Pali zovuta ndi izi, chifukwa kuchuluka kwa tizilombo tating'onoting'ono pa voliyumu imodzi ndikotsika kwambiri. M'malo ovuta, owuma, ozizira, omwe ali ndi mpweya wosowa kwambiri komanso cheza cha ultraviolet, tizilombo toyambitsa matenda timayenera kupanga njira zopulumutsira zomwe zimakhala ndi ma extremophiles. Mabakiteriya ndi bowa nthawi zambiri amafera komweko, koma ena amakhala ndi moyo popanga tinjere toteteza chibadwa.

Mabungwe a zakuthambo, kuphatikizapo NASA, ali osamala kuti asawonetse maiko ena ku tizilombo tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tisanayambe kuyendetsa chilichonse. Nthawi zambiri, tizilombo toyambitsa matenda sitingathe kukhala ndi moyo pa bombardment ya cosmic ray. Koma zamoyo za stratospheric zimasonyeza kuti zina zimatha kuchita. Inde, n’kofunika kukumbukira kuti kupulumuka sikufanana ndi kupita patsogolo kwa moyo. Chifukwa chakuti chamoyo chimapulumuka mumlengalenga ndipo, mwachitsanzo, kufika ku Mars, sizikutanthauza kuti chikhoza kukula ndi kuchulukana kumeneko.

Kodi izi zili choncho - funsoli likhoza kuyankhidwa ndi maphunziro atsatanetsatane a zamoyo za stratospheric.
