A group of scientists at The Scripps Research Institute has solved the structure of a protein that regulates the expression of genes by controlling the stability of mRNA -- an intermediate form of genetic information between DNA genes and proteins.
"Gene expression can be controlled at many levels, " says Scripps Research Professor Peter Wright, Ph.D., who is chairman of the Department of Molecular Biology and Cecil H. and Ida M. Green Investigator in Medical Research at Scripps Research. "One of them is at the level of the message."
The structure of the "tandem zinc finger" domain of the regulatory protein TIS11d in complex with a strand of mRNA was solved in the laboratory of Wright and H. Jane Dyson, Ph.D., by Maria A. Martinez-Yamout, Ph.D., of Scripps Research, and Brian P. Hudson, Ph.D., of Rutgers University. This is the first such structure to be solved, and it provides insights into the process of gene regulation at the atomic level.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
