Why Do We Freeze When Startled? New Study in Flies Points to Serotonin
A study in fruit flies, led by Richard Mann, PhD, has identified serotonin as a chemical that triggers the body’s startle response, the automatic deer-in-the-headlights reflex that freezes the body momentarily in response to a potential threat. The new study reveals that when a fly experiences an unexpected change to its surroundings, such as a sudden vibration, release of serotonin helps to literally stop the fly in its tracks momentarily. These findings offer broad insight into the biology of the startle response, a ubiquitous, yet mysterious, phenomenon that has been observed in virtually every animal studied to date.

Examining Genetic Risk Factors in Severe Birth Defect
A study, led by Dr. Yufeng Shen and Dr. Wendy Chung at Columbia University Irving Medical Center, investigated the genetic risk factors linked to congenital diaphragmatic hernia (CDH) and analyzed data from whole genome sequencing and exome sequencing to determine novel mutations. The study uncovered the link between CDH and additional developmental disorders. Researchers have been aiming to identify new risk genes in CDH—and other developmental disorders—with the hope that with improved genetic diagnosis more tailored or long-term care for patients born with this defect could be provided, as well as potential targets for intervention.

Systems Biology and Women's Health: A Q+A with Tal Korem, PhD
As a member of the Program for Mathematical Genomics, Tal Korem is bringing his interests in systems biology, quantitative research, and the human microbiome to areas of clinical relevance. For Dr. Korem, that clinical focus is women’s reproductive health. “There is still a lot we don’t understand that relates to women’s health, to fertility, and to birth outcomes, and how microbes play a role in all of this,” says Dr. Korem. In this Q+A, learn about Dr. Korem's ongoing research and his path to the field of systems biology and women's health.
