UT Southwestern Medical Center at Dallas researchers have shown that the absence of a key oxygen-sensing molecule can lead to multiple developmental defects - from an enlarged heart to eye problems.
The researchers generated the first mouse model that lacks entirely a member of an important family of proteins involved in sensing hypoxia, a state of reduced oxygen in the bodys cells that is associated with conditions such as heart attacks, stroke and lung disease.
This new model allowed the scientists to take a closer look into the exact physiologic function of these proteins, which was unknown until now, and the model provided clues as to what human diseases may be caused by alterations in these proteins. The researchers reported in the online version of Nature Genetics that the absence of this crucial oxygen-sensing molecule leads to developmental defects due to the inability of the mice to respond to high, damaging levels of oxygen-based molecules called reactive oxygen species.

A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna)
It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to...
Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols.
The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between radiation and matter. Light strikes particles...
Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.
Researchers at the Center for Nanoscale Materials (CNM), a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Argonne National...
A new research project at the TH Mittelhessen focusses on the development of a novel light weight design concept for leisure boats and yachts. Professor Stephan Marzi from the THM Institute of Mechanics and Materials collaborates with Krake Catamarane, which is a shipyard located in Apolda, Thuringia.
The project is set up in an international cooperation with Professor Anders Biel from Karlstad University in Sweden and the Swedish company Lamera from...
Superconductivity has fascinated scientists for many years since it offers the potential to revolutionize current technologies. Materials only become superconductors - meaning that electrons can travel in them with no resistance - at very low temperatures. These days, this unique zero resistance superconductivity is commonly found in a number of technologies, such as magnetic resonance imaging (MRI).
Future technologies, however, will harness the total synchrony of electronic behavior in superconductors - a property called the phase. There is currently a...
