A bacterial virus‚ named WO‚ was discovered to contain spider-like DNA. WO is a bacteriophage (phage)‚ a virus that infects and replicates within bacteria. It’s usual target is a bacterial parasite named Wolbachia. Wolbachia is found in 40% of arthropods and has recently been used to fight the Zika-carrying mosquitoes. Now‚ scientists realize they can use the virus to insert whatever gene they wanted into Wolbachia and then that would modify the mosquito from within. Animal genes were also found

The circulatory system of the locust‚ like all arthropods is open which differs from structure and function of the closed circulatory system that humans and other vertebrates have. A open circulatory system is suitable for the locust because of its small size. In an open system‚ blood (usually called hemolymph)

“The greatest thinker of the 19th century came close to being remembered as a footnote in the study of arthropods‚ solely because he feared disapproval.” Nando Pelusi’s “The Right Way to Rock the Boat” is an article that asserts how assertiveness is vital in order to thrive in modern day society‚ with the intention of convincing his audience to take action themselves. Assertiveness has played a major role throughout all of history‚ and has constantly evolved throughout time. Pelusi explains how most
