Researchers at the Consejo Superior de Investigaciones Científicas (CSIC) have discovered that the virus of infectious bursitis, considered by the scientific community, a living fossil, has an unusual structure: the capsid, the container of the genetic material of the pathogen is bigger than it needed to survive on their journey between infected and infected. The study, published in PNAS, explained that the virus uses its size to increase their infectivity. Moreover, the size of its capsid would have allowed virus to evolve towards more complex models, making it, according to the authors, in a "missing link" between the different families of viruses and a valuable object of study of evolution.

In general, viruses are composed of a nucleic acid capable of infecting a container and protein called capsid. As the researcher CSIC José Ruiz Castón, viruses represent a paradigm for the optimization of resources. In fact, it is surprising how carry out their vital functions, taking into account their limited genetic information content. "

There are currently undefined procedures by which treatment can be carried water to be purified or separated from the minerals and waste that detract from quality to it. Define the most appropriate treatment for water involves classifying the type of liquid you want to purify, since procedures vary for such work are made on salt water, wastewater, or water contaminated by industrial activity specific.

The various treatments that are performed in the case of wastewater can be classified broadly into physical and chemical treatments, biological treatments and chemical treatments, which have elements and special procedures and appropriate to this classification.
