Mancae are born with 6 segments and gain an additional one after their first molt. Whole woodlouse. While the broader phylogeny of the Oniscideans has not been settled, eleven infraorders / sections are agreed on with 3,937 species validated in scientific literature in 2004 [ 5 ] and 3,710 species in 2014 out of an estimated total of 5,000 ...
Asellus aquaticus can breed throughout the year, if the temperature is high enough: they do not breed under cold temperatures. Maturity can be reached in few months under warm summer temperatures, but maturation may take as much as two years in permanently cold water bodies (e.g., high-latitude or mountain waters). [3]
The above reaction occurs between a 1,2-aminothiol and a 2-cyanobenzothiazole to make luciferin, which is fluorescent. This luciferin fluorescence can be then quantified by spectrometry following a wash, and used to determine the relative presence of the molecule bearing the 1,2-aminothiol.

The azide-alkyne Huisgen cycloaddition is a 1,3-dipolar cycloaddition between an azide and a terminal or internal alkyne to give a 1,2,3-triazole. Rolf Huisgen [1] was the first to understand the scope of this organic reaction. American chemist Karl Barry Sharpless has referred to copper-catalyzed version of this cycloaddition as "the cream of ...
Bovicola bovis (also called Damalinia bovis and the red louse) is a cattle-biting louse found all over the world. It is a common pest of cattle of all types and sizes. They are one of many lice in the order Phthiraptera, but are divided from their blood sucking cousins in the sub-order Anoplura by the fact that they feed only by chewing.
On July 25, 1978, the world's first "test tube baby" was born. Louise Brown was the first person conceived through in vitro fertilization (IVF) and her birth eventually led to one of her doctors ...
Argulus foliaceus. Argulus foliaceus, also known as the common fish louse, is a species of fish lice in the family Argulidae. [1] It is "the most common and widespread native argulid in the Palaearctic" [2] and "one of the most widespread crustacean ectoparasites of freshwater fish in the world", considering its distribution and range of hosts.
