DNA-snipping protein called Cas9

Howard Hughes Medical Institute (HHMI) scientists have created a portrait of a DNA-snipping protein called Cas9 that reveals how the enzyme reshapes itself when it associates with an RNA molecule, creating a channel that lets it find and cleave its DNA target. The protein-RNA complex is a key component of a primitive bacterial immune system called CRISPR, and is also being used by researchers to cut specific DNA sequences in the laboratory for genome editing applications.

Salvador Dali – Ange Pi-Mesonic Review

Salvador Dali can be credited for being one of the greatest surrealist artists of all time. One of his accomplishments, Ange Pi-Mesonic, in my opinion, is truly one of his greatest and least praised works as an artist. The title of the picture can be translated as Pi-Mesonic Angel, a very strange yet suitable title. The word meson alludes to a class of elementary subatomic particles that participate in strong interactions, which forms the basis of the painting. This work is vigorous, effectual, and full of energy. It is a depiction of nuclear chaotic forces interacting in perfect unison.

Ange Pi-Mesonic was started in 1957 and completed in 1958. A vast majority of Dali’s pieces are oil on canvas. This illustration is just a little bigger than a regular sheet of paper. He used ink, pencil and a small amount of gouache to complete this piece. The picture may represent a dream of his, as most of his works appear to do. There is no real style association here, but it was labeled as divisionistic art. This does not adequately classify the drawing because divisionism is defined as a sub genre of neoimpressionism in which colors are divided into their components and mechanically arranged so that the eye organizes the shape. The eye cannot organize the shape of this piece, and thus the expectation that there is more than the basis of divisionism at work here. Divisionism, as defined from a scientific view, was a principle studied by Werner Heisenburg. This scientist suggested that matter might have several forms harmoniously coexisting within a single structure. It is strange that a scientific principle can label the work instead of a style of painting such as impressionism or renaissance.
