Stanford University Medical Center researchers have identified a protein responsible for ensuring correct skull growth in newborn mice. The protein, called Noggin, inhibits fusion of bony plates in the skull until developmentally appropriate. The scientists hope that Noggin may one day replace surgery as a way to treat premature skull fusion in infants.
"About 1 in 2,000 children has growth plates in their skull that fuse prematurely," said Michael Longaker, MD. "The brain is rapidly expanding in size during the first two years of life. If the brains container - the skull - cant expand in a similar fashion, you have a big problem." Left untreated, the condition can lead to mental retardation, blindness and seizures, as well as a severely misshapen head.
Longaker, a pediatric craniofacial surgeon at Lucile Packard Childrens Hospital and a professor of surgery at the School of Medicine, can correct the defect by removing sections of fused bone from an infants skull. But the operation is complex. And because its difficult to accurately predict how much room is needed for expansion, the procedure may need to be repeated as the brain grows.

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...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
