Polymerase chain reaction (PCR) is a revolutionary laboratory technique that enables the replication of a specific DNA sequence. Using PCR, millions of copies of a target DNA can be easily synthesized within a short period of time.

SARS-CoV-2 Omicron infections pose long-COVID risks despite reduced severity

researchers compared the post-coronavirus disease complaints and symptoms in individuals infected with the SARS-CoV-2 Omicron variant with those in individuals with Delta variant infections to understand whether the long-term complaints after Omicron infections are similar to those in infections with other SARS-CoV-2 variants.

CSU engineers introduce a better way to perform mosquito-tracking for disease applications

West Nile, Zika, dengue and malaria are all diseases spread by bites from infected mosquitoes. To track the threat of such diseases over large populations, scientists need to know where the mosquitoes are, where they've been, and where they might go.

Memory B and T cells responses differ when induced by SARS-CoV-2 infections or booster vaccinations

In a recent study published in The Journal of Immunology, a team of researchers from Japan examined the memory B and T cell responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein after the booster dose of the coronavirus disease 2019 (COVID-19) messenger ribonucleic acid (mRNA) vaccine BNT162b2.
