A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are stored, ideally they remain equivalent to freshly-collected ...

Jan 2022 for a 50% likelihood to limit global warming to 1.5 °C is 120 GtC (420 GtCO 2) – or 11 years of 2021 emissions levels. [ 60 ] Scientists propose and preliminarily evaluate a likely transgressed planetary boundary for green water in the water cycle , measured by root-zone soil moisture deviation from Holocene variability .
The term "biobank" first appeared in the late 1990s and is a broad term that has evolved in recent years. [1] [2] One definition is "an organized collection of human biological material and associated information stored for one or more research purposes."

DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections (also called "sequences"), an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of the UPC barcode ...
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon .
Gene specific primers are used to amplify the corresponding gene as with regular PCR and as a result data is usually only obtained for sample sizes of less than 100 genes. The inclusion of housekeeping genes , whose expression should be constant under the conditions, is used for normalisation.
