A new study from Johns Hopkins suggests that routine widening of the vagina, a procedure known as an episiotomy, does not reduce the risk of injury to infants during a complicated birth, such as when a babys shoulders are stuck in the birth canal after the head is already out. Instead, physicians can proceed directly to physical maneuvering of the infant, thereby avoiding unnecessary trauma to the mother and, at the same time, averting injury to the baby. An episiotomy should only be performed when more room is required to carry out maneuvers to dislodge an infant.
"Most textbooks in obstetrics still recommend that physicians perform a generous episiotomy, yet there is no evidence that the procedure will reduce the likelihood of injury to the infant," said high-risk obstetrician Edith Gurewitsch, M.D., an assistant professor at The Johns Hopkins University School of Medicine and lead author of the study, presented at the 24th annual meeting of the Society for Maternal-Fetal Medicine and set for publication in the American Journal of Obstetrics and Gynecology online Oct. 5.
"Episiotomy will only eliminate soft tissue barriers to delivery, whereas rotating the infant will realign its shoulders to fit within the mothers pelvis. It is the bony pelvis that is widely acknowledged as the main cause for the infant getting caught in the birth canal."

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
