Rett syndrome is a debilitating neurological disorder occurring primarily in girls. While some existing therapies might ease particular symptoms of the condition, there is no current way to address the syndrome at a molecular level. Now, researchers at Whitehead Institute for Biomedical Research, in collaboration with scientists at Brandeis University, have dramatically reduced certain manifestations of Rett Syndrome in mice, marking a clear path in which to explore possible therapies for people.
"This is the first time weve successfully reduced the awful symptoms of Rett syndrome using transgenic techniques," says Whitehead Member Rudolf Jaenisch, senior author of the paper that will be published February 2 in the journal Neuron. "Once we understand the molecular mechanisms of the disease we may be able to design rational strategies that may eventually be useful for the improving the condition in people."
Rett syndrome, whose incidence is roughly 1 in 15,000, is caused by a defective gene on the X chromosome. Most boys with Rett syndrome die before birth. Girls with Rett develop normally until about six to eighteen months, when things begin to go terribly wrong. Their health deteriorates, and they begin to show symptoms such as loss of speech, loss of voluntary motor control, constant hand wringing and seizures.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
