Johns Hopkins researchers, using a novel birthing simulator designed by biomedical engineering faculty, staff and students at the University, have identified what may be the least forceful way to deliver a baby whose shoulders are stuck in the birth canal.
Shoulder dystocia, in which the baby’s shoulders won’t move past the mother’s bony pelvis during delivery, occurs in about 5 percent of births. Of these, up to a quarter of deliveries may result in an injury to the baby’s brachial plexus, the nerves that control movement and sensation in the arm. As many as 10 percent of infants may sustain some permanent damage.
An obstetrician can perform one of several maneuvers to manipulate the position of either the mother or the baby when shoulder dystocia occurs. The Hopkins researchers found that turning the baby so its spine faces the mother’s belly (a technique known as anterior Rubin’s maneuver) requires less force than either turning the baby so its spine faces the mother’s spine, or moving the mother’s legs back to try to reduce the force of the baby’s shoulders against the mother’s pelvis.

Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
Just in time for Christmas, a Mars-analogue mission in Morocco, coordinated by the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) as part of the SRC project FACILITATORS, has been successfully completed. SRC, the Strategic Research Cluster on Space Robotics Technologies, is a program of the European Union to support research and development in space technologies. From mid-November to mid-December 2018, a team of more than 30 scientists from 11 countries tested technologies for future exploration of Mars and Moon in the desert of the Maghreb state.
Close to the border with Algeria, the Erfoud region in Morocco – known to tourists for its impressive sand dunes – offered ideal conditions for the four-week...
Research opens doors in photonic quantum information processing, optical signal processing and microwave photonics
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new integrated photonics platform that can...
A team of experimentalists at the U.S. Department of Energy's Ames Laboratory and theoreticians at University of Alabama Birmingham discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that compete with superconductivity.
"Superconductivity is a strange state of matter, in which the pairing of electrons makes them move faster," said Jigang Wang, Ames Laboratory physicist and...
