Cov kws tshawb fawb pom cov kab mob plaub muag-qhov loj tshaj plaws puas tau pom

Tojsiab

Cov kws tshawb fawb hauv Caribbean tau tshawb pom cov kab mob loj tshaj plaws uas paub, tuaj ntawm ib xees, lossis kwv yees li qhov loj ntawm tib neeg cov plaub muag - 5,000 npaug loj dua cov kab mob feem ntau.

Cov Lus Tseem Ceeb

Cov kws tshawb fawb ntawm cov kob ntawm Guadeloupe hauv Fab Kis Lesser Antilles pom cov kab mob nyob hauv ib pawg ntawm cov nplooj mangrove decaying, raws li tsab ntawv ceeb toom nyob rau hauv phau ntawv journal. Science luam tawm hnub Thursday.

Cell - hu ua thiomargarita magnifica- tuaj rau ntawm qhov loj ntawm 10 millimeters, ua rau nws thawj tus kab mob uas pom pom ntawm qhov muag liab qab.

Cov kab mob feem ntau yog kwv yees li 2 micrometers (lossis kwv yees li ob txhiab ntawm ib millimeters) ntev, thiab qee cov qauv loj li 750 micrometers (peb feem pua ​​​​ntawm ib millimeters), ua rau cov xov tooj tshiab tau tshawb pom kwv yees li 5,000 npaug loj dua li feem ntau. kab mob, raws li kev tshawb fawb.

Tom qab kawm txog cov kab mob uas siv cov fluorescence, x-ray thiab electron microscopes, cov kws tshawb fawb pom tau tias nws tuaj yeem "ua kom loj hlob ntau dua qhov kev txwv rau cov kab mob ntawm tes."

Kev Nkag Siab Hais

Jean-Marie Volland, tus kws tshawb fawb ntawm Lawrence Berkeley National Laboratory, hais rau BBC, "kom muab tej yam rau hauv kev xav, nws yog qhov sib npaug rau peb tib neeg kom ntsib lwm tus tib neeg uas yuav siab npaum li Mount Everest."

Txaus Ntshai Qhov Tseeb

Cov kws tshawb fawb hais tias tus kab mob no tsis ua tib yam li lwm cov kab mob feem ntau yuav nyob hauv ib txoj hauv kev tseem ceeb. Tsis zoo li feem ntau cov kab mob - uas muaj dawb-floating DNA - thiomargarita magnifica khaws nws cov DNA hauv cov seem ntawm nws lub cev, nthuav tawm cov yam ntxwv zoo ib yam li cov hlwb eukaryotic, cov hlwb nyuaj uas tsim cov nroj tsuag thiab tsiaj txhu, Volland hais rau BBC.

Tus Keeb Kwm Tseem Ceeb

cov thiomargarita magnifica qauv yog xub xub pom ntawm Guadeloupe hauv 2009, tab sis tsis tau tshawb fawb kom meej txog thaum tsis ntev los no. Cov kab mob tau thawj sab Xyoo 1675 los ntawm Antonie van Leeuenhoek, uas tau soj ntsuam cov kab mob hauv cov pas dej, dej nag thiab tib neeg qaub ncaug.
