In the quest to repair damaged DNA - a process believed crucial in combating ailments ranging from cancer to aging - antioxidant has been the Holy Grail. But findings published this week in Nature suggest oxidation isnt always the enemy.
Robert Hausinger and Timothy Henshaw
Scientists at Michigan State University, along with colleagues in England, have uncloaked a mechanism that uses oxygen to repair DNA - until now an unlikely part of the restorative recipe. Their work is published in the Sept. 12 issue of the British science journal Nature.
"This offers possibilities to anyone working in the DNA repair field who likely hasnt considered oxygenation before," said Robert Hausinger, an MSU microbiology and biochemistry professor. "The field has been so focused against it."

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...
