Milestone discovery of the 3-D structure and function of vinculin explains how this protein changes its shape to perform different functions in health and disease
The discovery of how a protein called vinculin undergoes exquisitely precise changes in its shape is helping to answer some major questions about the life of cells, the development of tissues and organs and the spread of cancer from one part of the body to another. These findings, to be published in the Jan. 8, 2004, issue of Nature, were made by scientists at St. Jude Childrens Research Hospital.
The newly recognized way that this protein can change its shape is important because slight changes in the shape of vinculin completely change its role in the cell, making the protein a versatile tool for completing different tasks. For example, by alternately changing its shape from active to inactive forms, vinculin can control the cells ability to remain stationary or move through its environment.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
