Researchers in Singapore, for the first time in the world, replicate the contractile ring’s structure by isolating a refined protein and placing it within a cell-imitation capsule.
All organisms grow and develop through the regenerative ability of cell division. An indispensable ability for all living beings, it can be said that life is defined by this process. Research into the nature of this process is of significant importance in biology and medical science.
When organisms undergo cell division, what is known as a contractile ring is created in the interior wall of a cell membrane. As this ring contracts, the cell is pinched into multiple daughter cells.
Although research in molecular and cellular biology has gradually shed light on the proteins that form and control the contractile ring, there are many aspects of its self-organizational structure that remain a mystery.
Professor Shin’ichi Ishiwata (Graduate School of Advanced Science and Engineering) and Research Assistant Makito Miyazaki’s (Research Institute for Science and Engineering) research team at the Waseda Bioscience Research Institute in Singapore (WABIOS) are the first in the world to replicate the contractile ring’s structure by isolating a refined protein and placing it within a cell-imitation capsule.
Furthermore, the team has reached an understanding of the self-organizational structure of the ring and the minimum requirements and physical conditions of its contraction properties. This achievement is expected to play a great role in understanding the overall workings of cell division.
If cell division can be fully understood, it will become possible to control this process. This is expected to lead to medical treatments in various fields that can for example, prevent cancer cells from multiplying, and promote the propagation of healthy cells. It is also possible that this research can be utilized to create artificial cells with self-propagation abilities.
The details of this research were published in the online English science magazine “Nature Cell Biology” on March 23.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
