UCLA researchers have developed the first map of gene regulation in human neurogenesis, the process by which neural stem cells turn into brain cells and the cerebral cortex expands in size. The scientists identified factors that govern the growth of our brains and, in some cases, set the stage for several brain disorders that appear later in life.
Scientists at the Virginia Tech Carilion Research Institute (VTCRI) have found that people with PTSD have an increased learning response to surprising events. While most everyone reacts to surprise, people with PTSD tend to pay even more attention to the unexpected.
In response to the increasing informal sharing of human milk, the Academy of Breastfeeding Medicine (ABM) has published guidelines to minimize the risk of this practice while enhancing the health benefits.
Scientists from four different institutions are working together to identify a biomarker for Alzheimer's Disease using mice that travel an 850-mile circuit to test the efficacy of special technology called Quest MRI.
A few simple, strategic changes can move people from sedentary behaviour to better health, a study by researchers at Western University says. A group of students who cued themselves with timers and text reminders for six weeks took more frequent breaks from prolonged sitting; and those cues became habits even after those six weeks.
Keeping egg cells in stasis during childhood is a key part of female fertility. New research sheds light on the role of epigenetics in placing egg cells into stasis through childhood. A team from Cambridge, Dresden and Munich discovered a distinctive pattern of epigenetic marks that are needed for egg cell stasis. If egg cells don't go into stasis they can't become mature eggs and they will never have the chance to form new life.
Japanese researchers revealed that abnormal delivery of zinc to lung cells contributes to obstructive pulmonary diseases. They further showed that mRNA splicing abnormalities are involved in the detailed mechanism. So far, the importance of zinc in the lung has only been understood from a nutritional aspect. This discovery is thought to be the first to clarify zinc's effects on the regulation of mRNA ligation (splicing), and its involvement in the onset of pulmonary diseases.
