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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
