In research that aims to illuminate the causes of human developmental disorders, Salk scientists have generated 168 new maps of chemical marks on strands of DNA -- called methylation -- in developing mice. The data can help narrow down regions of the human genome that play roles in diseases such as schizophrenia and Rett Syndrome.
On July 29 2020, a Special Collection of articles addressing current norms and practice in childbirth and probing how childbirth can be a positive and transformative life event for women publishes in the open-access journal PLOS ONE. The seven Research Articles stem from a four-year European COST Birth Action that brought together more than 120 scientists, practitioners, activists and policymakers from 34 countries.
A research team led by Dr. Alida Bailleul from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences has proved that remnants of bird ovaries can be preserved in the fossil record.
Evolutionary and developmental biologist Craig Albertson and colleagues at UMass Amherst report that they have identified a molecular mechanism that allows an organism to change the way it looks depending on the environment it is exposed to, a process known as phenotypic plasticity.
Though same-day access to IUDs increases the likelihood a woman will get the reproductive health care she wants and decreases the chance she'll become pregnant when she doesn't plan to, most providers in Ohio don't offer the service, a new study has found.
Scientists identify how a nonfunctioning CASK gene creates chaos in the brain.
Researchers from the Rovira i Virgili University in collaboration with researchers from the University of Utah have carried out a systematic review and meta-analysis evaluating the association between adiposity (normal weight, overweight, obesity, and low weight) and the sperm quality. Overweight and/or obesity were associated with low semen quality parameters and underweight category was likewise associated with low sperm normal morphology. According to the researchers, this work demonstrates the importance of adiposity in semen quality.
Animal patterns are a source of endless fascination, and now researchers at the University Bath have worked out how zebrafish develop their stripes.
Scientists at the Sloan Kettering Institute, the Koch Institute at MIT, and the Klarman Cell Observatory at the Broad Institute have identified an unusual cell state that emerges early in tumor evolution and supports a cancer's ability to outwit chemotherapy.
Princeton University researchers explored how patterns of protein activity direct fly embryonic development by using 'optogenetic' techniques to rapidly and precisely turn Ras/Erk signaling on and off. A paper published July 23 in Current Biology by Heath Johnson, Nareg Djabrayan, Stanislav Shvartsman and Jared Toettcher describes these findings.
