According to the said researcher, this project “is part of the attempt that many laboratories are currently making worldwide to get to know better the biology of stem cells and the conditions in which some of their varieties could be used to treat some diseases”. In this case, scientists are going to study neural stem cells of adult mouse brains which, after being differentiated from neurons in a lab, will be implanted into the damaged cerebral cortex of genetically identical mice.
As Carmen Estrada explained, there is a specific area in the adult rodents’ brain, the subventricular area, where new neurons are massively generated from neural stem cells during the animals’ life. Although this phenomenon does not exist in humans in normal conditions, stem cells have been also detected in that area, with the possibility of generating new neurons under certain circumstances.
With this project, researchers will obtain information about neural stem cells that remain in the brain after birth, and will analyse their properties while they are in lab cultures, as well as after being implanted into the host brain.
Scientists hope to determine the conditions that allow neuron differentiation and to identify potentially useful genes as regulators or markers of such process. Thus, they will determine to what extent the neurons obtained in culture have the typical molecular structure of cells of its phenotype in adult brains.
In short, these trials will allow to establish “whether or not suitable neurons from neural stem cells can be transplanted into the brain of another animal”. The results will allow scientists to get to know the evolution of transplants and provide useful data in order to develop a cellular therapy as part of the treatment of some diseases linked to neuronal death.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
