A step to further understanding of the process whereby genes are turned on and off in living organisms has been achieved by a team of researchers at the Hebrew University-Hadassah Medical School. Understanding of this process has substantial consequences for furthering the use of medical genetic engineering to grow new tissue to replace damaged or defective organs or to halt the growth of undesirable tumors.
The achievement is described in an article in the current issue of Nature magazine, written by Howard Cedar, the Harry and Helen L. Brenner Professor of Molecular Biology at the Medical School, together with Jianmin Zhang, Xu Feng, both graduate students from China; graduate student Tamar Hashimshony; and senior researcher Dr. Ilana Keshet. The article is entitled “Establishment of Transcriptional Competence in Early and late S-Phase.”
Generally speaking, said Prof. Cedar, a winner of the Israel Prize in biology, there are two kinds of genes in every cell—those which control the “housekeeping” duties which are necessary to keep all cells functioning, and specific genes which give each tissue its unique properties.

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...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
