Tokyo Institute of Technology Biologists use the term adaptive radiation to describe a phenomenon in which new species rapidly evolve from an ancestral species, often in response to changes in the local environment that lead to new biological niches becoming available. To understand this process, biologists often turn to the cichlids of Lake Victoria, in which over 500 species of the fish have evolved over the past 14,600 years. As Professor Masato Nikaido of Tokyo Tech explains, “The level o...

Scientists at Tokyo Institute of Technology (Tokyo Tech) have pioneered a novel method for producing supramolecular protein assemblies from protein crystals. Their approach involves strategically introducing mutations in a protein monomer to create disulfide bonds (S-S) between the building blocks of protein crystals at very specific sites. After isolating the protein crystals from the cells and dissolving them, these bonds create uniform, stable filaments. Such protein assemblies could find app...

Now, scientists at Tokyo Institute of Technology explore...

Published: April 21, 2021 Tokyo Tech utilizes a portion of the generous contributions made to the Tokyo Tech Fund to organize events for the wider community. One area of focus is science education support, which aims to develop intellectual creativity among elementary, middle, and high school students with the help of resources available at the Institute. On March 7, ten elementary school students and their guardians joined an online programming workshop hosted by Tokyo Tech High School of Scie...

 E-Mail IMAGE: A subset of mRNAs is preferentially delivered to vacuoles by autophagy. This mRNA delivery is coupled to mRNA translation. The persistence of ribosome association with mRNA enhances selective mRNA delivery... view more  Credit: Tokyo Tech Optimal cell function requires a fine balance between the synthesis and degradation of biomolecules. Autophagy is the process by which cells degrade and recycle their own components, helping to clean up and maintain the cells internal ...
