The Power of Symmetry

Symmetry is one of the most fundamental concepts in nature, and it can give rise to profound and wide-reaching physical effects. A one-dimensional wire, for example, has a different symmetry and very different mechanical properties to those of a two-dimensional sheet of the same material. Tomoya Hayata (PhD student, Univ. Tokyo and RIKEN) and Yoshimasa Hidaka (RIKEN iTHES Associate) have now studied the consequences of breaking symmetry for various systems found in nature, providing a powerful, general framework to describe the link between properties and symmetries. http://www.riken.jp/en//research/rikenresearch/highlights/7840/

    Person of the Week

    Yuji Sakai

    I'm Yuji Sakai, a member of the Theoretical Biology Laboratory. I received a Ph.D. in physics from Kyushu University in 2012. After that, I came to RIKEN. I was a member of Hatsuda Lab until last FY and belong to Mochizuki Lab now.

    I have studied nuclear physics, particularly how nucleus changes under extreme conditions, high temperature and high density that are related to the environment realized in early universe and cores of the compact stars respectively.

    The word ‘nucleus’ refers to two things, atomic nucleus and cell nucleus. Both are important for us. The former consists of protons and neutrons and it constructs materials around us and the latter contains DNA and it constructs ourselves.

    My resent research interest is physical properties of cell nucleus. DNA encodes the genetic instructions of organisms and a human cell’s DNA totals 2 m in length. The long DNA is packed in a very small spherical nucleus with diameter of 6 μm. In spite of the crowded system, DNA is copied and divided into two pairs correctly many times. I investigate physical mechanism of this mysterious cell division dynamics theoretically and numerically. I hope to interact with many researchers in different fields and learn a lot through iTHES project.
