Over the last few years, I have attended several political meetings concerned with the refugee crisis, multiculturalism or Indigenous rights in Australia, meetings at which liberal democratic–minded ‘left-wing’ people came together to discuss, or agitate for change in, governmental policies. At these meetings, I always found it difficult to accept the slogans on their placards and in their speeches: ‘Shame Australia! Reconciliation for a united Australia’, ‘Wake up Australia! We welcome refugees!’ or ‘True Australians are tolerant! Let’s celebrate multicultural Australia!’ (...) My uncomfortable feeling came not only from the fact that I was left out because of my Japanese nationality but also because I had never seen or heard words like ‘shame Japan’, ‘wake up Japan’ or ‘true Japanese are...’ at Japanese ‘left-wing’ political gatherings. In Japan, these are words used only by right-wing nationalists. Indeed it is difficult to even imagine liberal-left intellectuals in postwar Japan calling for a ‘true Japanese’ political response, such is the extent to which the idea of ‘good nationalism’ is now regarded as an oxymoron. This is my starting point for an essay in which I want to be attentive to the different roles played by national in the Japanese and Australian political environments. (shrink)

Egg or sperm? The mechanism of sexual fate decision in germ cells has been a long‐standing issue in biology. A recent analysis identified foxl3 as a gene that determines the sexual fate decision of germ cells in the teleost fish, medaka. foxl3/Foxl3 acts in female germline stem cells to repress commitment into male fate (spermatogenesis), indicating that the presence of mitotic germ cells in the female is critical for continuous sexual fate decision of germ cells in medaka gonads. Interestingly, foxl3 (...) is found in most vertebrate genomes except for mammals. This provides the interesting possibility that the sexual fate of germ cells in mammals is determined in a different way compared to foxl3‐possessing vertebrates. Considering the fact that germline stem cells are the cells where foxl3 begins to express and sexual fate decision initiates and mammalian ovary does not have typical germline stem cells, the mechanism in mammals may have been co‐evolved with germline stem cell loss in mammalian ovary.

Reversible acetylation at the ϵ‐amino group of lysines located at the conserved domain of core histones is supposed to play an important role in the regulation of chromatin structure and its transcriptional activity. One promising strategy for analyzing the precise function of histone acetylation is to block the activities of acetylating or deacetylating enzymes by specific inhibitors. Recently, two microbial metabolites, trichostatin A and trapoxin, were found to be potent inhibitors of histone deacetylases. Trichostatin A reversibly inhibits the mammalian histone (...) deacetylase, whereas trapoxin causes inhibition through irreversible binding to the enzyme. The histone deacetylase from a trichostatin A‐resistant cell line is resistant to trichostatin A, indicating that the enzyme is the primary target. Both of the agents induce a variety of biological responses of cells such as induction of differentiation and cell cycle arrest. Trichostatin A and trapoxin are useful in analyzing the role of histone acetylation in chromatin structure and function as well as in determining the genes whose activities are regulated by histone acetylation.

Previous research has shown that although infants follow the gaze direction of robots, robot gaze does not facilitate infants’ learning for objects. The present study examined whether robot gaze affects infants’ object learning when the gaze behavior was accompanied by verbalizations. Twelve-month-old infants were shown videos in which a robot with accompanying verbalizations gazed at an object. The results showed that infants not only followed the robot’s gaze direction but also preferentially attended to the cued object when the ostensive verbal (...) signal was present. Moreover, infants showed enhanced processing of the cued object when ostensive and referential verbal signals were increasingly present. These effects were not observed when mere nonverbal sound stimuli instead of verbalizations were added. Taken together, our findings indicate that robot gaze accompanying verbalizations facilitates infants’ object learning, suggesting that verbalizations are important in the design of robot agents from which infants can learn. Keywords: gaze following; humanoid robot; infant learning; verbalization; cognitive development. (shrink)

precise introduction to Advaita Vedanta, on the basis of something more.

A new field of gene expression regulation research is emerging that has previously been overlooked. This new area is concerned with distinguishing the expression of a single gene from the averaged expression of many gene copies within the cell population. This paper reviews research focused on individual genes in inducible gene expression systems. The main experimental strategy is to measure the gene expression level of a single cell containing a single reporter gene molecule. In contrast to the commonly held belief, (...) gene induction is found to be stochastic under certain conditions. The possible mechanisms and implications are discussed. (shrink)
