Researchers at the Virginia Bioinformatics Institute (VBI) and the Department of Horticulture in the College of Agriculture and Life Sciences at Virginia Tech have developed a new procedure for the efficient transfer of specific DNA sequences into the genome of strawberry. The scientists have used Agrobacterium tumefaciens, natures genetic engineer, to introduce DNA into the woodland or alpine strawberry Fragaria vesca.
The method takes advantage of Agrobacteriums circular DNA molecule (T-DNA) to deliver DNA to the plant. By helping researchers establish the function of large numbers of strawberry genes, this method could, in the long term, be extremely useful in enhancing the nutritional value of these plants as well as the amount of health-enhancing antioxidants that they may contain.
Jerzy Nowak, professor and head of the Department of Horticulture at Virginia Tech, commented: "Over the years, scientists have worked hard to find a system that would enable the efficient transformation of strawberry. However, these efforts have fallen short of the requirements to support large-scale studies of gene function in fruit crops." He added: "What sets this work apart is the concerted approach adopted by the researchers to combine different parameters that boost the efficiency by which foreign DNA is introduced into this economically important crop."

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...
