Nzira yekuzvidzivirira sei kubva kumwaranzi munzvimbo

Iyo Australian National University (ANU) yakagadzira new nanomaterial inogona kuratidza kana kufambisa mwenje painodiwa uye inodzorwa tembiricha. Sekureva kwevanyori veongororo iyi, izvi zvinovhura musuwo wetekinoroji inodzivirira vanoongorora muchadenga kubva kune inokuvadza mwaranzi.

Musoro weKutsvakurudza Mohsen Rahmani ANU yakati zvinhu izvi zvaive zvitete zvekuti mazana emachira aikwanisa kuiswa pamuromo wetsono, iyo inogona kuiswa kune chero nzvimbo, kusanganisira masutu emuchadenga.

Sample ye nanomaterial kubva kuANU pasi pekuyedzwa

Muganho webasa mumamillisieverts

Iyi ndiyo imwe yakazara uye yakarebesa yakatevedzana yemazano ekurwisa nekudzivirira kubva kune inokuvadza cosmic mwaranzi iyo vanhu vanooneswa kunze kwemhepo yePasi.

Zvipenyu zvinonzwa zvakashata muchadenga. Chaizvoizvo, NASA inotsanangura "miganho yebasa" yevazivi vemuchadenga, maererano nehuwandu hwehuwandu hwemwaranzi yavanogona kutora. muganhu uyu 800 kusvika 1200 millisievertszvichienderana nezera, murume kana mukadzi nezvimwe zvinhu. Iyi dhizaini inoenderana neyakakura njodzi yekuva nekenza - 3%. NASA haibvumiri njodzi yakawanda.

Avhareji yevagari vePasi inoratidzirwa kune approx. 6 millisieverts yemwaranzi pagore, inova mhedzisiro yekufumurwa kwechisikigo senge radon gasi uye granite countertops, pamwe nekufumurwa kusiri kwechisikigo kwakadai se x-ray.

Mamisheni emuchadenga, kunyanya ayo ari kunze kwesimba reMagineti ePasi, anosangana nemwaranzi yakakwira, kusanganisira nemwaranzi inobva kumadutu ezuva asina kurongeka anogona kukanganisa mwongo nenhengo. Saka kana tichida kufamba muchadenga, tinoda neimwe nzira kubata nehukasha hwemwaranzi yakaoma ye cosmic.

Kuratidzwa kwemwaranzi kunowedzerawo njodzi yevazivi vemuchadenga kugadzira akati wandei egomarara, genetic mutations, kukuvadzwa kwetsinga system uye kunyange cataracts. Mumakumi mashoma emakumi emakore apfuura echirongwa chemuchadenga, NASA yakaunganidza data rekuratidzwa kwemwaranzi kune vese vayo venyeredzi.

Parizvino hatina dziviriro yakagadziridzwa kubva mumwaranzi inouraya yemucosmic. Mazano ekugadzirisa anosiyana kubva pakushandisa ivhu kubva asteroids sezvivharo, mushure dzimba dzepasi paMars, yakagadzirwa kubva kuMartian regolith, asi pfungwa dzacho dzakanaka kunze zvakadaro.

NASA iri kuongorora hurongwa Kudzivirirwa kwemwaranzi yemunhu kune interplanetary ndege (PERSEO). Inofungidzira kushandiswa kwemvura sechinhu chekusimudzira, chakachengeteka kubva mumwaranzi. hovhorosi. Iyo prototype iri kuedzwa mukati meInternational Space Station (ISS). Vesainzi vari kuyedza, semuenzaniso, kana muzivi wemuchadenga achikwanisa kupfeka sutu yemuchadenga yakazadzwa nemvura obva aidurura pasina kutambisa mvura, inova chitubu chakakosha zvikuru muchadenga.

Iyo kambani yeIsrael StemRad inoda kugadzirisa dambudziko nekupa mwaranzi nhovo. NASA neIsrael Space Agency vakasaina chibvumirano pasi peiyo AstroRad radiation yekudzivirira vest ichashandiswa panguva yeNASA EM-1 mishoni yakatenderedza Mwedzi uye kuInternational Space Station muna 2019.

Kufanana neshiri dzeChernobyl

Sezvo upenyu huchizivikanwa kuva hwakatangira papasi rakanyatsochengetedzwa kubva mumwaranzi yepasi, zvipenyu zvepanyika hazvikwanisi zvikuru kurarama pasina iyi nhovo. Imwe neimwe mhando yekuvandudzwa kwehutachiona hutsva hwechisikigo, kusanganisira nemwaranzi, inoda nguva yakareba. Zvisinei, pane zvakasiyana.

Chinyorwa "Kurarama kwenguva refu redhiyo kuramba!" pane webhusaiti yeOncotarget

Chinyorwa cheScience News cha2014 chakatsanangura kuti zvipenyu zvakawanda munzvimbo yeChernobyl zvakakuvadzwa sei nekuda kwekuwanda kwemwaranzi. Zvisinei, zvakazoitika kuti mune dzimwe shiri dzakawanda izvi hazvisizvo. Zvimwe zvacho zvakatanga kusada kupiswa nemwaranzi, zvichikonzera kudzikira kwemazinga ekukuvadzwa kweDNA uye kuwanda kwemahara radicals ane ngozi.

Pfungwa yekuti mhuka hadzingochinji nemwaranzi, asi dzinogona kutogadzira mhinduro yakanaka kwairi, ndeyevazhinji kiyi yekunzwisisa kuti vanhu vanogona sei kujairana nemhoteredzo ine mwero wakakwira wemwaranzi, senge chitundumuseremusere, nyika yekunze, kana interstellar. nzvimbo..

Muna Kukadzi 2018, chinyorwa chakabuda mumagazini yeOncotarget pasi pechirevo "Vive la radiorésistance!" ("Rarama kwenguva refu radioimmunity!"). Iyo ine chekuita nekutsvagisa mumunda weradiobiology uye biogerontology yakanangana nekuwedzera kuramba kwevanhu kune radiation mumamiriro ezvakadzika nzvimbo colonization. Pakati pevanyori vechinyorwa, chinangwa chavo chaive chekutsanangura "mepu yemugwagwa" yekuzadzisa mamiriro ekusadzivirirwa kwevanhu kuburitsa redhiyo, kubvumira mhuka dzedu kuongorora nzvimbo pasina kutya, inyanzvi kubva kuNASA's Ames Research Center.

Mazano ari kutenderera munharaunda yevatsigiri ve "adaptation" yemuviri wemunhu kune cosmos inonzwika inonakidza. Imwe yacho, semuenzaniso, ichave yekutsiviwa kwezvakanyanya zvinoumba mapuroteni emuviri wedu, zvinhu hydrogen uye kabhoni, ine inorema isotopes, deuterium uye C-13 kabhoni. Kune dzimwe, nzira dzinozivikanwa zvishoma, dzakadai semishonga yekubayisa neradiation therapy, gene therapy, kana kuvandudzwa kwetishu padanho remasero.

Zvechokwadi, kune maitiro akasiyana zvachose. Anoti kana denga richinyanya kuvenga biology yedu, ngatingorambai tiri paNyika uye kuti michina isinganyanyi kukuvadza mwaranzi iongororwe.

Zvisinei, mafungiro emhando iyi anoita seakanyanya kupesana nezviroto zvevanhu vekare zvekufamba muchadenga.
