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.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
