Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

International Journal of Cancer, Volume 158, Issue 6, Page 1489-1497, 15 March 2026.What's new? Breast cancer results from a combination of genetic and environmental causes, and the cumulative effect of stressful life events may be a contributing factor. Here, the authors analyzed data from cohort and twin‐pair studies including 36 years of follow‐up to find out how stressful life events affect breast cancer risk. They found that even

Marital Status and Unobserved Heterogeneity - Do twins suggest a genetic inheritance? [PDF]
The purpose of this study is to reveal the importance of unobserved heterogeneity on marital status. The results for monozygotic (identical) and dizygotic twins indicate an important genetic component in marital status.

Stem-Like Adaptive Aneuploidy and Cancer Quasispecies [PDF]
, 2013 We analyze and reinterpret experimental evidence from the literature to argue for an ability of tumor cells to self-regulate their aneuploidy rate. We conjecture that this ability is mediated by a diversification factor that exploits molecular mechanisms

Discordance in monozygotic Parkinson's disease twins – continuum or dichotomy?
Annals of Clinical and Translational Neurology, 2019 Differences in concordance rates between monozygotic and dizygotic twin pairs with Parkinson's disease (PD) have been used to estimate genetic influences in PD pathogenesis.

Epigenetics, 2012 We describe monozygotic twins discordant for childhood leukemia and secondary thyroid carcinoma. We used bisulfite pyrosequencing to compare the constitutive promoter methylation of BRCA1 and several other tumor suppressor genes in primary fibroblasts ...

genesis, Volume 64, Issue 1, February 2026.ABSTRACT To determine whether TXNDC15 variation causes Meckel–Gruber syndrome (MKS), we assessed the pathogenicity of the frameshift variant c.560delA. A CRISPR–Cas9 generated mouse model carrying the equivalent Txndc15 c.512delA mutation was analyzed at embryonic day 15.5.

Does Early Life Health Predict Schooling Within Twin Pairs? [PDF]
A large number of studies in labor economics estimate the returns to schooling using data on monozygotic twins, under the assumption that educational attainment is random within twin pairs. This exogeneity assumption has been commonly questioned, however,

Identifying Causal Genotype–Phenotype Relationships for Population‐Sampled Parent–Child Trios
Genetic Epidemiology, Volume 50, Issue 1, February 2026.ABSTRACT The process by which genes are transmitted from parent to child provides a source of randomization preceding all other factors that may causally influence any particular child phenotype. Because of this, it is natural to consider genetic transmission as a source of experimental randomization.

Beyond DNA: Epigenetics and Proteomics in Forensic Science [PDF]
, 2016 The use of genetic evidence in criminal cases is well established and has improved the public opinion and credibility of forensic science. However, several shortcomings associated with current genetic profiling techniques exist. Scientific research aimed
