Fertilization narratives are powerful biological stories that can be used for social ends, and 20th-century artists have used fertilization-based imagery to convey political and social ideas. In Danae, Gustav Klimt used an esoteric stage of early human embryos to indicate successful fertilization and the inability of government repression to stifle creativity. In Man, Controller of the Universe, Diego Rivera painted a mural of a man controlling an ovulating ovary, depicting Trotsky's view that society will rationally regulate human fertilization. His former wife, Frida Kahlo, refuted this view in Moses: Nucleus of Creation, wherein she painted images of fertilization and embryo formation as the ultimate acts of erotic consummation and generation.

Identification and characterisation of differentially regulated genes in preimplantation human embryonic development are required to improve embryo quality and pregnancy rates in IVF. In this study, we examined expression of a number of genes known to be critical for early development and compared expression profiles in individual preimplantation human embryos to establish any differences in gene expression in fresh compared to frozen–thawed embryos used routinely in IVF. We analysed expression of 19 genes by cDNA amplification followed by quantitative real-time PCR in a panel of 44 fresh and frozen–thawed human preimplantation embryos. Fresh embryos were obtained from surplus early cleavage stage embryos and frozen–thawed embryos from cryopreserved 2PN embryos. Our aim was to determine differences in gene expression between fresh and frozen–thawed human embryos, but we also identified differences in developmental expression patterns for particular genes. We show that overall gene expression among embryos of the same stage is highly variable and our results indicate that expression levels between groups did differ and differences in expression of individual genes was detected. Our results show that gene expression from frozen–thawed embryos is more consistent when compared with fresh, suggesting that cryopreserved embryos may represent a reliable source for studying the molecular events underpinning early human embryo development.

Abstract Due to the inaccessibility of post-implantation human embryos and the restriction on in-vitro fertilization (IVF) embryos cultured beyond 14 days, the knowledge of early post-implantation human embryogenesis remains extremely limited. Recently, we have developed a microfluidic in-vitro platform, based on human pluripotent stem cells (hPSCs), which is capable of recapitulating several key developmental landmarks of early human post-implantation embryonic development, including lumenogenesis of the epiblast (EPI), amniogenesis, and specification of primordial germ cells (PGCs) and of primitive streak (PS) cells. Given its controllability and reproducibility, the microfluidic platform provides a powerful experimental platform to advance knowledge of human embryology and reproduction. This protocol describes the preparation of the microfluidic device and its implementation for modeling human post-implantation epiblast and amnion development using hPSCs.

Most of what we know about the Universe has been gleaned from the study of stars, and a major achievement of 20th-century science was to understand how stars work and their lifecycles from birth to death. ‘Stars’ describes this lifecycle beginning with star formation when a cloud of interstellar gas suffers a runaway of its central density. It then considers nuclear fusion, key stellar masses, and life after the main sequence when the star burns its core helium. The surfaces of stars are described along with stellar coronae and exploding stars—both core-collapse and deflagration supernovae. Finally, globular star clusters, solar neutrinos, stellar seismology, and binary stars are discussed.

With these words, Henry Roth beganCall It Sleep, a novel published in 1934 when its author was twenty-eight years old.Call It Sleepranks among the most powerful novels of the 20th century, precisely because of the questions it does ask about the conflicts of immigrant life, the demands of assimilation, and the search for spiritual nourishment in the modern world. Roth locates his narrative in New York City during the peak years of mass migration from Europe between 1907 and 1914. At the center ofCall It Sleepis David, a precocious and sensitive child at age six, who is already questioning his place in the universe and the meaning of God. Thus,Call It Sleeppresents a narrative of how a small immigrant boy makes sense of his world, a world defined by both its physical and spiritual dimensions.
