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.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
