Dean’s Award for Outstanding Achievement, Graduate School of Frontier Sciences 2017 2017:03:30:11:49:58
The recipients of the Dean's Award for Outstanding Achievement (Master course 12 students, Doctoral course 12 students) GSFS 2017 were announced. The awards were initiated in 2006 for the purpose of recognizing students and groups for outstanding achievement in academic learning, international exchange, and regional contribution. A ceremony was held on Wednesday March 15, and Dean Takashi Mino awarded plaques to the recipients.

Discovery of mechanism of asymmetric cell division in fertilized egg cells in plants 2016:12:09:10:14:28
An international group of plant biologists have succeeded for the first time in visualizing how egg cells in plants divides unequally (asymmetric cell division) after being fertilized. The direction of this asymmetric cell division determines the body axis of flowering plants, i....

Sperm production induced in female silkworms 2016:11:04:14:51:22
Scientists reveal key gene that determines malenessA group of University of Tokyo researchers and their collaborators embedded a male sex gene into the genome of female silkworms and found that they developed male reproductive glands and started producing sperm, as well as displa...

New approach to evaluate irradiation effect on whole body 2016:07:05:14:48:19
Analysis of 3,600 serial sections of medaka after local irradiationA University of Tokyo joint research group has developed a method of applying a heavy particle beam (a beam of accelerated carbon ions) used in cancer radiotherapy to the whole body of a medaka (killifish) and the...

Effects of space on medaka gene expression 2015:10:16:10:38:04
A University of Tokyo joint research group analyzed gene expression of medaka cultured in the International Space Station Kibo module for two months and found alteration in several signaling pathways related to stress responses in most organs. These results suggested that common stress responses occurs in space environment in both fish in an aqueous environment and mammals.

Riddle of mimicry of unpalatable butterfly 2015:04:14:9:31:47
Molecular mechanism of Batesian mimicry in Papilio polytesUniversity of Tokyo researchers have revealed the whole genome sequences of two swallowtail butterflies Papilio polytes, the females of which mimic the unpalatable butterfly Pachliopta aristolochiae, and Papilio xuthus, wh...

Medaka as a tool for studying human diversity and evolution 2015:01:16:16:41:44
Variations in appearance (such as eye color, hair color, facial features, among others) are observed in worldwide human populations. However, there also exists geographical variation in sexual differences, such as body size, often referred to as sexual dimorphism in the literature. In general, sexual differences among human Asian groups are smaller than that of African or European populations. However, the molecular evolutionary mechanisms of these differences are still relatively unknown.

Mechanisms producing diverse coloration patterns in caterpillars 2014:10:17:11:00:39
Single novel gene apontic-like controls patterns It is known that eye spots on the larvae of butterflies and moths (caterpillars) function as aposematic (warning) signals to predators, and that the complex brown patterns on larvae of the ancestral strain of the silkworm camouflag...

The controlling mechanisms of mimicry 2008:03:03:16:45:12
Insects often mimic to other models to protect them from predators or to prey other insects. The studies of mimicry have been carried out from the view points of ecology or ethology so far, but the controlling mechanisms of mimicry have not been studied well. Young caterpillars ...
