Br512: an improved DNA polymerase for isothermal amplification assays
Unmet need Loop-mediated isothermal amplification (LAMP) is a technique that allows for nucleic acid amplification without the need for a thermocycler. This technology enables testing for infections practically anywhere. Testing shortages have exacerbated the COVID-19 pandemic, and there is a high demand for tests that can provide rapid results outside...

Size-Fractionated Plankton Tow
Inventors at the University of Arizona have developed a netting system designed to separate particles of varying sizes while conducting plankton tows. This configurable setup allows for different sized particles to be separated as they are collected. It also includes improvements made from standard plankton netting, including stability improvements...
