Since 1978, about 5 million babies have been born from in vitro fertilization, and most of those children are biologically related to their parents. However, about 50,000 babies conceived via in vitro come from donor eggs. We talk with Dr. Linda Kahn, Postdoctoral Fellow in Pediatrics at New York University School of Medicine; Dr. Richard Paulson, Professor of Reproductive Medicine at University of Southern California and and Dr. Wendy Chavkin, Professor of Public Health and Obstetrics and Gynecology at Columbia University about:
The arguments in favor of more regulation of the egg donation industry
What we don’t know yet about the long term effects of the process
The health and economic concerns for donors who donate multiple times
The importance of educating the public about the complexity and risks involved

New research indicates that shifting your sleep schedule by as little as one hour can lead to fatigue, increased grumpiness and sleepiness, which is referred by scientists as “social jetlag.” Sierra Forbush, a researcher at the University of Arizona-Tucson, says that social jetlag is comparable to jet lag, but instead of feeling tired because of the change in time zones, people feel tired because of the change in their social responsibilities. Further, it turns out that everyone experiences the same amount of social jetlag, regardless of age or gender.
Did you know that 86% of people say that they shift their sleeping schedule on the weekend? Even with so many people changing their sleeping schedule weekly, we don’t really know much about why it affects our health in the way that it does. What we do know is that when we wake up earlier or later than what we’re accustomed to, we can trigger a hormonal change that leads to fatigue and irritation. So, even if you sleep longer on the weekends, what affects your health and mood is not the amount of sleep you get, but the disruption in the natural cycle of sleep that your body is used to.
