As early as one or two days after a stroke, that is, far earlier than was previously thought, the formation of new nerve cells and blood vessels gets underway in the affected area. This is indicated by findings in a dissertation by Wei Juang at Umeå University in Sweden.
Stroke is most often caused by a blockage of one of the heart’s blood vessels, which results in disrupted blood flow, so-called ischemic stroke. Brain damage occurs directly and spreads for the first few critical days. After that, the brain damage starts to heal, a process that can take many months and even years. It is not known what lies behind the capacity of the brain to recover.
In her dissertation Wei Jiang found that new formation of blood vessels, angiogenesis, starts in the brain as early as 24-48 hours after a stroke, that is, far earlier that was previously thought. Moreover, she found new formation of nerve cells in the damaged area. The newly generated nerve cells could be seen after seven days and were still in evidence up to 60 days after the damaged occurred. This new formation of blood vessels and nerve cells can be critical to the healing of the brain and offers the potential for entirely new treatments.

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...
