Rare collectible dreidels from Cochin are made from iron; they are black in colour decorated with silver markings, made by an intricate Bidriware style process. The Guinness World Record for Most Valuable Dreidel [37] was achieved by Estate Diamond Jewelry in November 2019 and was valued at $70,000 ($83,421 in current dollars, adjusted for ...
Many laboratory animals, including mice and rats, are chronically stressed which can also negatively affect research outcomes and the ability to accurately extrapolate findings to humans. [ 32 ] [ 33 ] Researchers have also noted that many studies involving mice, rats and other rodents are poorly designed, leading to questionable findings.
Most animals are used in only one procedure: animals are frequently euthanized after the experiment; however death is the endpoint of some procedures. [134] The procedures conducted on animals in the UK in 2017 were categorised as: 43% (1.61 million) sub-threshold, 4% (0.14 million) non-recovery, 36% (1.35 million) mild, 15% (0.55 million ...

Fortrea primate-testing lab, Vienna, Virginia, 2004–05. Most of the NHPs used are one of three species of macaques, accounting for 79% of all primates used in research in the UK, and 63% of all federally funded research grants for projects using primates in the U.S. [25] Lesser numbers of marmosets, tamarins, spider monkeys, owl monkeys, vervet monkeys, squirrel monkeys, and baboons are used ...
Springtails (class Collembola) form the largest of the three lineages of modern hexapods that are no longer considered insects.Although the three lineages are sometimes grouped together in a class called Entognatha because they have internal mouthparts, they do not appear to be any more closely related to one another than they are to all insects, which have external mouthparts.
The fly D. melanogaster is the most widely used animal in genetic studies. This comes from the simplicity of breeding and housing the flies, which allows large numbers to be used in experiments. Molecular biology is relatively simple in these organisms and a huge variety of mutant and genetically modified flies have been developed. [7]
This list of Latin and Greek words commonly used in systematic names is intended to help those unfamiliar with classical languages to understand and remember the scientific names of organisms. The binomial nomenclature used for animals and plants is largely derived from Latin and Greek words, as are some of the names used for higher taxa , such ...
