New findings from a team of Marshall University Joan C. Edwards School of Medicine researchers reveal urban and rural differences in prenatal exposure to essential and toxic elements.
For nearly 100 years biologists have argued about how exactly natural selection can possibly work. If nature selects the individuals with the best genes then why aren't all organisms the same? What maintains the genetic variation that natural selection acts upon, the genetic variation that has ultimately led to the spectacular diversity of life on Earth today? Recent findings made at Uppsala University suggest that the answer could be sex.
New findings about the causes of a rare genetic disorder that affects mainly boys, known as MeCP2 duplication syndrome, may inform the development of treatments for the condition.
New research on children exposed to Zika during their mothers' pregnancies finds that by age 12 to 18 months, significant problems were present in 6.25 percent of children who were evaluated for eye abnormalities, 12.2 percent of children evaluated for hearing problems, and 11.7 percent of children evaluated for severe delays in language, motor skills and/or cognitive function who also had brain imaging. In all, 14.5 percent had at least one of the three abnormalities.
Scientists from the Salk Institute discovered a new protein complex that keeps the brakes on stem cells, allowing them to maintain their indefinite potential. The new complex, called GBAF and detailed in Nature Communications on Dec. 3, 2018, could provide a future target for regenerative medicine.
A new computational model developed by researchers from The City College of New York and Yale gives a clearer picture of the structure and mechanics of soft, shape-changing cells that could provide a better understanding of cancerous tumor growth, wound healing, and embryonic development.
While other animal embryos grow outside the mother, their embryonic cells can get right to work accepting assignments, such as head, tail or vital organ. By contrast, mammalian embryos must first choose between forming the placenta or creating the baby. New research at MSU has pinpointed two proteins that are the keys to this decision making. The process of assigning cells to placenta or baby is important because that is when pluripotent cells are made. These adaptable pluripotent cells are critical to stem cell research.
Researchers at the Nara Institute of Science and Technology (NAIST) report AGAMOUS and CRABS CLAW partner in a feed-forward system to terminate the floral meristem and form the gynoecium in Arabidopsis plants. The findings give new understanding on the epigenetics that determine fruit number and size.
Vitamin C may reduce the harm done to lungs in infants born to mothers who smoke during their pregnancy, according to a randomized, controlled trial published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
New research from the University of Adelaide's Robinson Research Institute supports the need for dietary and lifestyle interventions before overweight and obese women become pregnant.
