The Marvels of Shapes Revealed by Mathematics

The person who I interviewed this time is Dr. Daisuke Ohtsuka, who works in the Laboratory for Developmental Morphogeometry, one laboratory at the BDR that is headed by a team leader with a non-biology background. I thought our conversation might include a lot of references to numbers and mathematical formulas, but as Dr. Ohtsuka himself […]

View from the seventh floor of the Developmental Biology Building

The Akashi Kaikyo Bridge connects the Honshu mainland (right) to Awaji Island (left) and is located across the sea approximately 18 km away from the Kobe Campus. At 3,911 meters long, it is the second longest suspension bridge in the world. The cape in the foreground extending from the right is where the ancient port of Kobe, Owada no tomari, is said to have been located.

Vol.10 – Spring 2022

On the cover: A growing baby corn? This is an electron microscope image of an olfactory sensillum found on the head of a fruit fly. Nanometer-sized (one-millionth of a millimeter) odorant molecules can pass through tiny pores (nanopores) on the sensillum surface to stimulate the nerves inside for detecting odors. In contrast, micrometer-sized (one-thousandth of […]

Approaching the Origin of Life with Structural Biology

It has been a while since I last talked to a structural biology researcher. I know that they use instruments like nuclear magnetic resonance (NMR) spectrometers to determine the structure of proteins, but I was very excited to be able to hear the story of what happens after the structure is determined as it sounded […]

Molecular structure of proteins

Light blue hammock?
This is a graphic model of the three-dimensional structure of the DOCK-ELMO-Rac protein complex. DOCK (cyan) is involved in cell movement and maturation. The biological activities in the body are maintained by the binding and unbinding of proteins to other proteins.

Neural Organogenesis Research Program, RIKEN BDR-Otsuka Pharmaceutical Collaboration Center

Launched in 2016, the RIKEN BDR-Otsuka Pharmaceutical Collaboration Center aspires to conceive novel and original results through collaborative research investigating disease mechanisms based on developmental, regenerative and systems biology approaches. In June 2020, the Neural Organogenesis Research Program headed by Hideya Sakaguchi was established to accelerate research specifically in areas of neurobiology and the understanding of neurodegenerative diseases.

Follow the heart

Follow the heart

This time, we have Dr. Akane Sakaguchi from the Kimura Lab. I was surprised to learn that she makes decisions based on her intuition, which was different from what I expected judging from her neat appearance. I guess we could call her an intuitive person. She is doing research on the heart, and the way […]

fruit fly mutants

Vol. 07 – Spring 2021

Different fly species?
These are in fact all the same fruit fly species Drosophila melanogaster.
Their different appearances are due to one or multiple genetic mutations, which lead to black bodies, white eyes, etc. There is one wild-type (normal) fly and mutant flies with 20 different phenotypes. Can you identify them all?
