Genetic code yekunyora zvinhu nematsotsi
Mabhakodhi nemaQR macode anoshandiswa kunyora zvese kubva kumaT-shirts muzvitoro zvembatya kuenda kumainjini emotokari anogona kukurumidza kutsiviwa neDNA-based labeling system isingaonekwe nemeso chete isingakwanise kubviswa kana manyepo.
Muchinyorwa chakaburitswa muNature Communications, masayendisiti kubva kuYunivhesiti yeWashington neMicrosoft akapa molecular labeling systeminonzi Nungu. Maererano nevatsvakurudzi. Zvichanetsa kuti matsotsi aone obva abvisa kana kuchinja DNA tag zvinhu zvakakosha kana zvisina njodzi zvakaita semapepa ekuvhotesa, mabasa ehunyanzvi kana magwaro akaiswa.
Pamusoro pezvo, ivo vanoti mhinduro yavo, kusiyana neakawanda mamwe mamaki, inodhura. "Kushandisa DNA kunyora zvinhu kwanga kwakaoma kare nekuti kunyora nekuiverenga kunowanzo dhura zvakanyanya uye kunotora nguva, uye kunoda michina yemurabhoritari inodhura," munyori anotungamirira wekudzidza paYunivhesiti yeWashington mudzidzi akaudza AFP. Katy Doroshchak.
Porcupine inokutendera kuti ugadzire zvidimbu zveDNA pamberikuti vashandisi vakasununguka kugadzira ma tag matsva. Iyo Porcupine labeling scheme yakavakirwa pakushandiswa kweseti yeDNA tambo dzinodaidzwa kuti molecular bits, kana "molbits" kwenguva pfupi, sekureva kwakabudiswa nepepanhau kubva kuYunivhesiti yeWashington.
"Kuti encode identifier, tinosanganisa yega yega dhijitari nemolbit," Doroschak anotsanangura. "Kana iyo dhijitari iri 1, tinoiwedzera kune tag, uye kana iri 0, isu tinoifuratira. Izvi zvinoteverwa nekuomeswa kwetambo dzeDNA kudzamara dzagadzirira kudhirowa kunotevera. Kana chigadzirwa chacho chakanyorwa, chinogona kutumirwa kana kuchengetwa. " Kana mumwe munhu achida kuverenga chiratidzo, kunyorovesa uye kuverenga ne nanoporous sequencer, muverengi weDNA idiki pane iPhone.
Kusiyana neiyo iripo yekumaka zvinhu masisitimu, mukuwedzera kune dziviriro, iyo DNA-yakavakirwa nzira inogona zvakare kumaka zvinhu zvingave zvakaoma kubhakodhi.
“Hazvikwanisike kucherechedza donje kana mamwe machira nenzira dzechinyakare sekuti RFID tags uye, asi iwe unogona kushandisa mhute-inoverengeka DNA-yakavakirwa identifier, ”Doroshchak anotenda. "Izvi zvinogona kushandiswa mumaketani ekugovera uko kuteedzera kwakakosha kuchengetedza kukosha kwechigadzirwa."
DNA label iyi haisi pfungwa itsva, asi kusvika pari zvino yave ichizivikanwa zvikuru kubva mubasa remapurisa anorwisa matsotsi. Kune zvigadzirwa zvakadai Sarudza DNA Marking spray, inoshandiswa kudzivirira nekudzivirira kurwiswa kwevanhu uye mamwe mabasa eutsotsi. Izvi zvinobatsira munyaya yemhosva dzinoparwa nematsotsi pa mopeds uye midhudhudhu. Iyo aerosol inocherekedza mota, zvipfeko uye ganda revatyairi vese nevatyairi vane yakasarudzika macode asi isingaonekwe DNA inopa humbowo hwemberi hunobatanidza vapari vemhosva.
Imwe mhinduro inozivikanwa se DNA Guardian, inoshandisa isingakuvadzi kune hutano, yakasarudzika coded, inotariswa UV mwenje tsvina inoramba iri paganda uye zvipfeko kwemavhiki akawanda. Kutonga kwakafanana neSelectaDNA labeling spray.
