Dog qhov ntswg: muaj dab tsi piv rau nws?

Tias yog vim li cas tib neeg tau ntev pib siv lub peev xwm ntawm cov dev no rau lawv tus kheej lub hom phiaj:

• Cov dev pab nrog kev tshawb nrhiav hluav taws. Lawv lub qhov ntswg tuaj yeem hnov ​​​​ntxhiab txog ib txhiab daus las ntawm cov roj av - tseem tsis tau muaj qhov sib piv rau txoj kev tshawb nrhiav cov kab ntawm kev tua hluav taws.
• Cov dev pab tub ceev xwm thiab tub rog nrhiav tshuaj, foob pob thiab lwm yam khoom tawg.
• Lawv pab nrhiav tib neeg los ntawm kev hnov ​​tsw thaum lub sijhawm tshawb nrhiav thiab cawm.
• Tsis ntev los no nws tau pom tias cov dev tuaj yeem raug cob qhia kom kuaj tau qee yam mob qog noj ntshav, suav nrog qog nqaij hlav zes qe menyuam thiab prostate, melanoma thiab mob ntsws cancer, nrog rau txhawm rau kuaj malaria thiab Parkinson tus kab mob. Raws li kev tshawb fawb los ntawm Medical Detection Dogs, cov dev tuaj yeem raug cob qhia kom paub qhov tsis hnov ​​​​tsw ntawm kev mob, sib npaug ntawm ib qho teaspoon qab zib diluted nrog dej hauv ob lub pas dej da dej Olympic.

Tab sis qhov teeb meem yog tias tsis muaj ntau tus dev tau kawm hauv txhua qhov no. Thiab lawv cov kev cob qhia yog kim heev, yog li muaj qhov tsis txaus ntawm "dab qhov ntswg". Yog li ntawd, nws tsis yog qhov xav tsis thoob tias cov kws tshawb fawb xav tsim cov peev txheej txawv txawv no nrog kev pab ntawm cov khoom siv tshuab, kev siv tshuab lossis cov khoom siv hluavtaws.

Kev tshawb fawb puas tuaj yeem tsim ib qho analogue ntawm tus dev lub qhov ntswg?

Ntawm Massachusetts Institute of Technology, physicist Andreas Mershin, nrog rau nws tus kws cob qhia Shuguang Zhang, tau ua ntau txoj kev tshawb fawb los kawm seb tus dev lub qhov ntswg ua haujlwm li cas, thiab tom qab ntawd tsim cov neeg hlau uas tuaj yeem tsim cov txheej txheem no. Raws li qhov tshwm sim ntawm ntau yam kev sim, lawv tau tswj hwm los tsim "Nano-nose" - tej zaum qhov no yog thawj qhov kev sim ua tiav los tsim kom muaj kev hnov ​​tsw tsw ntxhiab tsw. Tab sis rau tam sim no, Nano-Nse no tsuas yog lub tshuab ntes, zoo li lub tshuab ntsuas carbon monoxide, piv txwv li - nws txhais tsis tau cov ntaub ntawv nws tau txais.

Startup Aromyx tab tom sim siv cov kev xav tsis zoo ntawm cov ntxhiab tsw rau kev lag luam. Lub tuam txhab xav muab tag nrho 400 tib neeg olfactory receptors rau ntawm ib nti, tsis zoo li Nano-Nse, uas tsuas yog siv li ntawm 20 receptors tshwj xeeb, nyob ntawm seb qhov xav tau siv.

Lub hom phiaj ntawm tag nrho cov haujlwm no yog los tsim ib yam dab tsi uas yuav hnov ​​​​tsw tsw zoo ib yam li tus dev lub qhov ntswg. Thiab tej zaum nws tsis nyob deb.

Tab sis cov dev puas muaj qhov ntswg zoo tshaj?

Qhov tseeb, muaj ob peb lwm hom tsiaj uas muaj qhov hnov ​​tsw zoo heev thiab tseem ua ntej ntawm cov dev hauv qhov no.

Nws ntseeg tau tias qhov mob siab tshaj plaws ntawm cov ntxhiab tsw hauv ntxhw: lawv pom cov noob loj tshaj plaws uas txiav txim siab tsw. Elephants tuaj yeem qhia qhov txawv ntawm tib neeg pawg neeg hauv Kenya, raws li kev tshawb fawb xyoo 2007: ib pab pawg (Masai) tua thiab tua ntxhw, thaum lwm pab pawg (Kamba) tsis ua.

Dais kuj zoo dua rau dev. Txawm hais tias lawv lub hlwb yog ob feem peb me dua tib neeg, lawv qhov hnov ​​​​tsw tsw zoo dua 2 npaug. Piv txwv li, ib tug polar dais tuaj yeem hnov ​​tus poj niam ntawm ib puas mais deb.

Cov nas thiab nas kuj paub txog lawv qhov hnov ​​tsw tsw. Thiab ib tug loj dawb shark tuaj yeem hnov ​​​​txawm tias ib qho ntshav poob los ntawm ntau tshaj ib mais deb.

Tab sis nws yog tseeb hais tias tag nrho cov tsiaj no, tsis zoo li dev, pab tsis tau ib tug neeg, yog vim li cas nws yog tus aub tus ntxhiab uas muaj nuj nqis heev los ntawm tib neeg.
