One of the best ways to figure out how far a virus like COVID-19 has spread in a community is to test for it. This step-by-step guide explains how coronavirus swab-the-nose-and-throat tests work, and ...

Digital PCR, or dPCR, is a molecular biology technique that detects and quantifies nucleic acid targets. By partitioning a sample into many individual reactions, scientists can measure whether a ...

As the coronavirus that causes the COVID-19 disease spreads across the world, the IAEA, in partnership with the Food and Agriculture Organization of the United Nations (FAO), is offering its support ...

PCR is a technique used to amplify target DNA in a sample. It’s a well-known method that has undergone numerous modifications to enhance its capabilities. This year, it’s turning 40 years old. PCR has ...

A new same-day detection strategy shows how simple, low-cost lab steps can uncover Salmonella in meats, vegetables, and dairy far faster than traditional methods. This could offer a powerful tool for ...

PCR—the workhorse of modern molecular biology—is charging forward using both conventional and digital methods to explore single cells and even single molecules. Nathan Blow reports. In late 1978, Ry ...

A team of UK-based scientists has recently developed an allele-specific probe polymerase chain reaction method that can accurately detect different variants/lineages of severe acute respiratory ...
