The nation’s streets are filled with protesters shouting for justice after separate grand juries in new york and missouri declined to indict two white police officers who killed unarmed black men while on duty. the decision by the grand juries in those cases has raised questions about their validity, especially given their secrecy. grand juries can serve a variety of purposes at both the state and federal levels, said rebecca lonergan, associate professor at the usc gould school of law. in criminal cases, the grand jury can be a way for prosecutors to bypass the preliminary hearing phase of a trial. the prosecutor presents all the evidence to a grand jury, which — instead of a judge — decides whether there is enough evidence to file charges and send the accused straight to a trial.

julius caesar turned the roman republic into the roman empire by coming in and taking the "dictator" role during the time of a civil war (elites vs lower classes) winning battles and reputation, then declaring him dictator for life

hope this : )

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
