Kuperewera kwa Malangizo a Pulasitiki Pipette Kukuchedwetsa Kafukufuku wa Biology

Kumayambiriro kwa mliri wa Covid-19, kuchepa kwa mapepala akuchimbudzi kudasokoneza ogula ndikupangitsa kuti azichulukirachulukira komanso chidwi chochulukirapo m'njira zina monga ma bidets. Tsopano, vuto lofananalo likukhudza asayansi mu labu: kuchepa kwa zinthu zotayidwa, zosabala zapulasitiki, makamaka malangizo a pipette, Sally Herships ndi David Gura lipoti la NPR's The Indicator.

Malangizo a Pipettendi chida chofunikira chosinthira kuchuluka kwamadzimadzi mu labu. Kafukufuku ndi kuyesa kokhudzana ndi Covid-19 kudalimbikitsa kufunikira kwakukulu kwa mapulasitiki, koma zomwe zimayambitsa kusowa kwa mapulasitiki zimapitilira kuchuluka komwe kumafunikira. Zinthu kuyambira nyengo yoopsa mpaka kuchepa kwa ogwira ntchito zakhala zikudutsana m'magawo ambiri azinthu zomwe zimasokoneza kupanga zinthu zofunika za labu.

Ndipo asayansi amavutika kulingalira momwe kafukufuku angawonekere popanda malangizo a pipette.

"Lingaliro lotha kuchita sayansi popanda iwo ndi loseketsa," akutero woyang'anira labu ya Octant Bio Gabrielle Bostwick ku.Nkhani za STAT' Kate Sheridan.

Malangizo a Pipetteali ngati turkey basters omwe afupikitsidwa mpaka mainchesi ochepa okha. M'malo mwa babu labala kumapeto komwe amafinyidwa ndikumasulidwa kuti amwe madzi, nsonga za pipette zimagwirizanitsa ndi chipangizo cha micropipette chomwe wasayansi angachikhazikitse kuti atenge kuchuluka kwamadzimadzi, nthawi zambiri amayezedwa mu microliters. Malangizo a Pipette amabwera mosiyanasiyana ndi masitayelo a ntchito zosiyanasiyana, ndipo asayansi nthawi zambiri amagwiritsa ntchito nsonga yatsopano pasampuli iliyonse kuti apewe kuipitsidwa.

Pa mayeso aliwonse a Covid-19, asayansi amagwiritsa ntchito maupangiri anayi a pipette, a Gabe Howell, yemwe amagwira ntchito yogawa ma lab ku San Diego, akuuza NPR. Ndipo United States yokha ikuyesa mamiliyoni a mayesowa tsiku lililonse, chifukwa chake kusowa kwaposachedwa kwa pulasitiki kumayambira kumayambiriro kwa mliri.

"Sindikudziwa za kampani iliyonse yomwe ili ndi zinthu zomwe zikugwirizana ndi kuyesa kwa [Covid-19] komwe sikunakhale ndi chiwopsezo chachikulu chomwe chidakulitsa mphamvu zopanga zomwe zidalipo," atero a Kai te Kaat, wachiwiri. Purezidenti wa kasamalidwe ka pulogalamu ya sayansi ya moyo ku QIAGEN, kwa Shawna Williams kuWasayansimagazini.

Asayansi omwe akuchita kafukufuku wamitundu yonse, kuphatikiza ma genetics, bioengineering, kuwunika kobadwa kumene ndi matenda osowa, amadalira malangizo a pipette pantchito yawo. Koma kusowa kwazinthu kwachedwetsa ntchito ina pakapita miyezi, ndipo nthawi yomwe imagwiritsidwa ntchito pofufuza zinthu imachepetsa nthawi yochita kafukufuku.

"Mumangowononga nthawi yochulukirapo kuti mutsimikizire kuti muli pamwamba pa zomwe zili mu labu," akutero University of California, San Diego, katswiri wa sayansi ya zamoyo zopanga Anthony Berndt.Wasayansimagazini. "Timakhala nthawi yayitali tsiku lililonse ndikufufuza mwachangu malo osungiramo katundu, ndikuwonetsetsa kuti tili ndi chilichonse ndikukonzekera masabata asanu ndi limodzi mpaka asanu ndi atatu amtsogolo."

Nkhani yogulitsira imapitilira kuchuluka kwa kufunikira kwa mapulasitiki omwe adatsata mliri wa Covid-19. Pamene mphepo yamkuntho ya Uri inagunda ku Texas mu February, kuzima kwa magetsi kunagunda zomera zomwe zimapanga polypropylene resin, zopangiramalangizo a pulasitiki, zomwe zapangitsa kuti nsongazo zikhale zochepa, malipotiNkhani za STAT.
