While extraction of DNA from water samples provides a convenient and non-invasive way to study aquatic biodiversity, reliable evidence that this approach is accurate enough to estimate the number of fish per species and their biomass in natural habitats, is still lacking. A new study, published in the open-access, peer-reviewed journal Metabarcoding and Metagenomics, demonstrates the high precision of the method, after comparing environmental DNA data with manually collected information from a fishery farm.
Overlooked data sources offer considerable opportunity to support companies' growth.
Recently, there have been a number of electric vehicle (EV) battery fire incidents. Unlike the batteries used in small mobile devices, such as smartphones, the battery pack of an EV is composed of hundreds of battery cells, and any instability can cause major casualties and property damage. Amid various efforts to pinpoint the cause of battery fires, Korean researchers have developed a new analysis method to evaluate the thermal stability of EV batteries.
