A new study indicates an essential role for a maternally inherited gene in embryonic development. The study found that zebrafish that failed to inherit specific genetic instructions from mom developed fatal defects earlier in development, even if the fish could make their own version of the gene.
For the first time the functions of natural killer cells in the womb have been identified. Researchers at the University of Warwick and University Hospitals Coventry and Warwickshire (UHCW) NHS Trust have discovered the role that they play in preparing the womb for pregnancy.
Researchers have developed a new tool to sequence chloroplast DNA from hundreds of plants at once, to learn more about how plant populations move. This tool, CallHap, makes it cheaper and easier to sequence the chloroplast genomes of large numbers of plants and accurately track seed dispersal across landscapes.
A new study led by SBP describes the biology behind why muscle stem cells respond differently to aging or injury. The findings, published in Cell Stem Cell, have important implications for the normal wear and tear of aging.
Thanks to Veilleux and Laimbeer, it will soon be easier to breed the perfect potato chip or to access desirable traits such as enhanced disease resistance in wild or primitive species.
Researchers at IRB Barcelona unravel the role of the histone BigH1 in the development of male sex cells from stem cells. The study, which was performed in Drosophila melanogaster, paves the way to a greater understanding of male infertility. Published in Cell Reports, the work sheds light on the mechanisms through which histones regulate how stem cells give rise to differentiated cells.
Researchers have found a new potential treatment that may alleviate complications of babies born smaller than they should be, also called fetal growth restriction, which refers to poor growth of the fetus in the mother's womb during pregnancy. The findings were published in The Journal of Physiology.
Based on a decade of data from Pennsylvania, researchers report that babies born to mothers living within 1 kilometer of active 'fracking' wells are 25 percent more likely to exhibit low birth weight -- a risk factor for infant mortality, ADHD, asthma, and other negative outcomes. The results reflect a possible health consequence of exposure to fracking pollutants. To date,
Wild-derived house mice call at higher rates and frequencies during interactions with the opposite sex than with the same sex, according to a study published Dec. 13, 2017, in the open-access journal PLOS ONE by Sarah Zala from Konrad Lorenz Institute of Ethology, Austria, and colleagues.
The conversion of tropical forests to crop and pastureland has long been a concern for scientists, a new study points to another unexpected consequence: changes in fish production.
