1 June 2012 – Portland State University researchers have discovered a virus that may provide clues about the collective origin and evolutionary history of viruses – the most abundant organisms on earth. The newly discovered virus is a medley of sequences from different types of genetic material representing a previously unknown combination. The genome of this hybrid virus sequence contains genes homologous to both previously identified RNA and DNA viruses. The identification of a hybrid virus sequence indicates that at some point in time, viruses with different types of genetic material were swapping genes.
In this modern world of constantly evolving technology, researchers today have the advantage of extensive technological resources that allow them to take their questions to a new level.One such resource is still growing, but has already increased scholars’ ability to reach out and use materials that had once been unavailable. Online databases and the digitization of libraries and museum collections have opened up an unprecedented opportunity for collaboration and comprehension.
Microgreens are seven- to ten-day-old seedlings of various vegetable crops that are packaged as young shoots, including both cotyledons and hypocotyls. To improve the marketability of this highly perishable product, shelf life must be extended by controlling respiration rates. Little information is available describing the post-harvest characteristics of this high value specialty crop, and its respiration rates have not yet been carefully quantified. The present study aims to investigate the respiration rates and shelf life of microgreens.
Education relies on the ability to continually learn and has often been considered a social science rather than a physical science. Advances in neuroscience now allow us to approach learning and intelligence from a scientific standpoint. There is a persistent problem of unequal access to quality education as well as broad social issues that stem from not having a solid education to grow from. In order to provide a conceptually solid attempt to the solution, I work to apply our understanding of cognitive science to this social issue.
