Elastic titanium nails help children recover faster from a broken leg than the traditional treatment with weeks of traction and a body cast, according to a new study from The Childrens Hospital of Philadelphia. Children with the implanted nails got out of bed within days after surgery, were less dependent on their parents for help in moving, and had fewer complications than children in body casts.
"Weve shown that although both treatments usually have good outcomes, treatment with elastic nails allows children more rapid mobility and the ability to resume normal daily activities in half the time of the traditional traction and cast treatment," said Jack Flynn, M.D, pediatric orthopaedic surgeon at The Childrens Hospital of Philadelphia and primary investigator of this study. The research teams study appeared in the April issue of the Journal of Bone and Joint Surgery.
Different than hardware nails, elastic nails are implanted flexible pins that are inserted into the broken bone to support the pieces while the bone heals. The nails are approximately 15 to 20 inches in length and about the width of a radio antenna. Often two nails are necessary for treatment of a fracture. Surgeons remove the nails after the fracture heals, typically six to nine months after surgery.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
