The matricellular protein Drosophila Cellular Communication Network Factor is required for synaptic transmission and female fertility
Evelyne Ruchti, Brian Donal McCabe
Within the extracellular matrix, matricellular proteins are dynamically expressed nonstructural proteins that interact with cell surface receptors, growth factors, and proteases, as well as with structural matrix proteins. The cellular communication networ ...
Bethesda2022Human reproduction is regulated by retrotransposons derived from ancient Hominidae-specific viral infections
Didier Trono, Julien Paul André Pontis, Yu Tao
The transcription factor network required for primordial germ cell (PGC) specification is known to diverge in mammals. Here the authors show that hominidae-specific transposable element (TE) LTR5Hs becomes transcriptionally active during PGC specification, ...
NATURE PORTFOLIO2022Medipix4, a high granularity four sides buttable pixel readout chip for high resolution spectroscopic X-ray imaging at rates compatible with medical CT scans
Medipix4 is the latest member in the Medipix/Timepix family of pixel detector chips aimed at high rate spectroscopic X-ray imaging using high-Z materials. The chip address the limitations of conventional hybrid pixel detectors for X-ray imaging. Its predec ...
EPFL2022International Migration And The Growth Of Zurich, 1836-1949
The role played by international migration and its interactions with other demographic components in the process of city growth remains underappreciated. We analyze trends in natural increase and in net internal and international migration in Zurich during ...
INST NATL D ETUDES DEMOGRAPHIQUES2021Socioeconomic development predicts a weaker contraceptive effect of breastfeeding
The contraceptive effect of breastfeeding remains essential to controlling fertility in many developing regions of the world. The extent to which this negative effect of breastfeeding on ovarian activity is sensitive to ecological conditions, notably mater ...
NATL ACAD SCIENCES2021KRAB zinc finger protein-mediated control of transposon-embedded regulatory sequences from human germline to early embryos
Transposable elements (TEs), also called jumping genes, are genetic elements capable of changing their position within the genome of their host. They make up large fractions of genomes, including 45% of human DNA content, according to current estimates.
S ...
EPFL2021Both diversity and functional composition affect productivity and water use efficiency in experimental temperate grasslands
Charlotte Grossiord, Margaux Clara Lou Didion-Gency
Many experiments have shown that biodiversity promotes ecosystem functioning and stability and that this relationship varies with resource availability. However, we still have a poor understanding of the underlying physiological and ecological mechanisms d ...
WILEY2021The Emergence and Diffusion of Birth Limitation in Urban Areas of Developing Countries
The rising heterogeneity of women in terms of family size over the course of the fertilitytransition challenges the classic hypothesis about the diffusion of birth limiting behaviors acrossparities, known as family limitation. We evaluate whether birth lim ...
Max Planck Institute for Demographic Research2020The emergence of birth limitation as a new stage in the fertility transition in sub-Saharan Africa
The fertility transition started later in sub-Saharan Africa than in other regions of the world. Moreover, the average number of children per woman declined more slowly there, owing to a distinct mechanism of fertility reduction. It has been argued that th ...
2020New architecture for the analog front-end of Medipix4
Jean-Michel Sallese, Adil Koukab, Viros Sriskaran
The Medipix4 chip is the latest member of the family of Medipix pixel detector readout chips aimed at high rate spectroscopic X-ray imaging. Unlike its predecessors, it will be possible to tile the chip on all 4 sides permitting seamless large area coverag ...
