Road signs and traffic signals on DNA

The DNA genomes of organisms whose cells possess nuclei are packaged in a highly characteristic fashion. Most of the DNA is tightly wrapped around protein particles called nucleosomes, which are connected to each other by flexible DNA segments, like pearls on a necklace. This arrangement plays a major role in deciding which genes are actively expressed, and thus which proteins can be synthesized in a given cell. Researchers have recently developed a model which explains the distribution of nucleosomes around the functionally crucial transcription start sites.

Understanding gate oxide trapping - one electron at a time

Using a new technique, researchers from imec, TU Vienna, and Infineon have shown that both electron and hole capture and emission times in SiO2 and HfO2 dielectrics are strongly thermally activated. The new technique, Time Dependent Defect Spectroscopy (TDDS), can be used to study the capture and emission times of single oxide defects over a very wide time range.
