Expanding the genetic code: the world’s first truly unnatural organism
From time immemorial, every living thing has shared the same basic set of building blocks - 20 amino acids from which all proteins are made.
That is, until now: A group of scientists say they have, for the first time, created an organism that can produce a 21st amino acid and incorporate it into proteins completely on its own. The research should help probe some of the central questions of evolutionary theory.
The findings are scheduled to appear in the Jan. 29 print edition of the Journal of the American Chemical Society, a peer-reviewed journal of the worlds largest scientific society. The article was initially published Jan. 4 on the journals Web site.

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...
