Researchers at Washington University School of Medicine in St. Louis have developed a new probe that allows them to watch protein activity in living cells. In their initial study, which focused on a protein tentatively linked to the spread of cancerous cells, the team both proved their new technique works and revealed surprising new details about the protein’s activity.
The protein in this study, neuronal Wiskott–Aldrich syndrome protein (N-WASP), is naturally found in every cell in the body and is known to be involved in a wide range of cellular processes. One of its key functions is believed to be guiding cellular growth and movement within the body, including when tumor cells metastasize, or spread, from one organ to another.
“To our knowledge this is the first probe of its kind that allows us to actually see in a living system where, when and how proteins are activated,” says first author Michael E. Ward, a graduate student in anatomy and neurobiology. “This is significant progress in moving from examining the biochemistry of ground up cells to being able to study it in an intact cell.”

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.

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...
How do some neutron stars become the strongest magnets in the Universe? A German-British team of astrophysicists has found a possible answer to the question of how these so-called magnetars form. Researchers from Heidelberg, Garching, and Oxford used large computer simulations to demonstrate how the merger of two stars creates strong magnetic fields. If such stars explode in supernovae, magnetars could result.
