To aid orthodontists in use of new orthoscrew
The newly Food and Drug Administration-approved orthoscrew--so tiny it is dwarfed by a fingertip--is difficult to place between the narrow spaces of teeth roots and bone.
Young Jin Jeon, a visiting assistant professor at the Case Western Reserve University School of Dental Medicine and an orthodontist from Pusan National University in Korea, developed a new grid device during his yearlong residency at Case that will help orthodontists accurately place and guide the newly approved mini-orthoscrews without damaging the teeth.
Called the JJ Aligner, which looks like a tiny half-inch plastic square of graph paper, is attached by the orthodontist to patients jaw and then x-rayed to show where teeth roots and bone are in relations to the grid. After the patients gum tissue has been numbed (much like that for a dental filling), the orthodontist will implant the screw using the combination of the x-ray and the grid as a guide. Jeon has a patent pending in Korea on the device. When he returns to Korea at the end of June, he plans to form a company to manufacture the grids for the eventual use in Korea and the United States.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
