Atypical centrioles during sexual reproduction
Front. Cell Dev. Biol., 2015 Centrioles are conserved, self-replicating, microtubule-based, 9-fold symmetric subcellular organelles that are essential for proper cell division and function.

Advanced Science, EarlyView.This work proposes a novel strategy targeting gut microbiota for managing polycystic ovary syndrome (PCOS). Inulin, a gut microbiota modulator, notably boosts the growth of short‐chain fatty acids (SCFAs)‐producers, represented by Bifidobacterium, thereby improving glucolipid metabolism and ovarian function of PCOS through suppressing the inflammatory ...

Elemental models of primate nursing and weaning revisited
American Journal of Biological Anthropology, Volume 180, Issue 1, Page 216-223, January 2023., 2023 Abstract Objectives Intra‐tooth patterns of trace elements barium (Ba) and strontium (Sr) have been used to infer human and nonhuman primate nursing histories, including australopithecine and Neanderthal juveniles. Here, we contrast the two elemental models in first molars (M1s) of four wild baboons and explore the assumptions that underlie each ...

A mathematical analysis of the evolutionary benefits of sexual reproduction [PDF]
arXiv, 2015 The question as to why most higher organisms reproduce sexually has remained open despite extensive research, and has been called "the queen of problems in evolutionary biology". Theories dating back to Weismann have suggested that the key must lie in the creation of increased variability in offspring, causing enhanced response to selection. Rigorously

De Novo Reconstruction of 3D Human Facial Images from DNA Sequence
Advanced Science, EarlyView.This study introduces Difface, a novel deep‐learning model for reconstructing 3D facial images only from DNA data. By integrating transformer networks, spiral convolutions, and a diffusion model, Difface directly aligns high‐dimensional SNP data with 3D facial structures.

Examination of runs of homozygosity in relation to height in an endogamous Namibian population
American Journal of Biological Anthropology, Volume 180, Issue 1, Page 207-215, January 2023., 2023 Abstract Objectives Height is a complex, highly heritable polygenic trait subject to both genetic composition and environmental influences. Recent studies suggest that a large proportion of height heritability is determined by the cumulative effect of many low allele frequency variants across the genome. Previous research has also identified an inverse

Mutation, Sexual Reproduction and Survival in Dynamic Environments [PDF]
arXiv, 2015 A new approach to understanding evolution [Val09], namely viewing it through the lens of computation, has already started yielding new insights, e.g., natural selection under sexual reproduction can be interpreted as the Multiplicative Weight Update (MWU) Algorithm in coordination games played among genes [CLPV14].

Origins of eukaryotic sexual reproduction.
Cold Spring Harbor Perspectives in Biology, 2014 Sexual reproduction is a nearly universal feature of eukaryotic organisms. Given its ubiquity and shared core features, sex is thought to have arisen once in the last common ancestor to all eukaryotes.
