  Virology is the scientific study of viruses, their structure, function, and impact on living organisms. Viruses are unique entities, existing at the boundary between life and non-life, requiring host cells to reproduce. This field covers the classification of viruses, their methods of replication, and the various ways they interact with hosts, often causing diseases. Understanding virology is crucial for studying infectious diseases like influenza, HIV, and COVID-19, as well as for developing antiviral therapies and vaccines. This chapter sets the foundation for exploring how viruses shape both health and the environment. 
    
  Definition and Scope of Virology 
  Virology is the branch of science that deals with the study of viruses and virus-like agents, including their structure, classification, genetics, and interaction with host organisms. As microscopic entities that straddle the line between living and non-living, viruses are unique. They are unable to carry out metabolic processes on their own, and must infect a host cell to replicate. This dependence on living organisms is what makes them distinct from other pathogens, such as bacteria and fungi. Despite their simple structure—typically comprising genetic material (DNA or RNA) encased in a protein coat—viruses have a profound impact on all forms of life, from humans to plants and animals.

  Space's Hidden Forces - How Dark...

  For centuries, humans have gazed up at the night sky in awe, wondering what lies beyond the stars. With the invention of powerful telescopes, astronomers began mapping galaxies, studying their motion, and uncovering patterns in how they moved through space. But something strange started to appear in the data. Galaxies were spinning in ways that defied the known laws of gravity. Based on what could be seen—the stars, dust, and gas—the galaxies should have been flying apart. The visible mass simply wasn’t enough to account for the gravitational pull holding everything together. This marked the beginning of a great cosmic mystery. 
  In the 1930s, Swiss-American astronomer Fritz Zwicky made one of the first observations that hinted at this invisible force. He studied a cluster of galaxies and noticed that they were moving too fast to be held together by the visible matter alone. He proposed the existence of “dunkle Materie,” or dark matter—an unknown substance that made up the missing mass. At the time, his ideas were largely ignored or dismissed as speculative. But in the decades that followed, more evidence began to emerge, and dark matter slowly gained credibility within the scientific community. 
  Fast forward to the 1970s, astronomer Vera Rubin provided some of the most convincing evidence that dark matter was real. By analyzing the rotation curves of spiral galaxies, she showed that stars far from the center of galaxies were moving just as quickly as those near the core. According to Newtonian physics, the stars on the edges should move slower, as the gravitational pull should weaken with distance from the center. But that wasn’t happening. Something unseen was holding these stars in orbit, acting like a glue that bound the galaxies together. This unseen substance, which does not emit, absorb, or reflect light, became known as dark matter.

  From Chaos to Stability - How...

  Israel Rosenfield, Edward Ziff

  At the heart of Israel Rosenfield and Edward Ziff's inquiry is the nature of brain function. The sensory world is disordered and chaotic. There are no labels for tables, chairs, or airplanes, and indeed there are no colors, sounds, or smells, only photons, airwaves, odorant molecules, and so on, which are unlabeled and impossible to "know." 
   
   
   
  To make sense of this chaos, the brain must simplify the sensory inputs by creating, or inventing, the colors, sounds, smells, forms, and faces that are perceived in consciousness, which become a proxy for the chaotic world in which we live. The brain's ability to generalize and categorize these invented perceptions, and to relate them to one another, enables it to form memories, which are not fixed representations of things past, but a dynamic and malleable function of the brain that is relational. 
   
   
   
  When formation of these worlds breaks down, neurological differences arise. Although the mechanisms that transform sensory chaos into the simplified perceptions experienced in consciousness remain elusive, Rosenfield and Ziff relate what they have learned by means of imaging brain activity and by mapping the neural circuits that comprise memory traces. In addition, the authors offer perspectives for future studies of consciousness.
