“Wheat is tremendously important” says Dr Graham Moore (project leader at the JIC), “it is a staple crop for a large proportion of the world’s population as well as the most important crop in North European agriculture. Unfortunately, the genome of wheat is very complex and that makes both studying its biology and using genetics to improve the quality of the crop, very difficult. The comprehensive genetic libraries that we are making available will help scientists and breeders who are seeking to improve the performance of wheat in agricultural systems around the world”.
The genome of wheat is 5x larger than that of humans and includes a total of 150,000 genes. The BAC libraries are collections of fragments of the wheat genome. Each fragment on average carries 1 or 2 genes and in total there are over 1.2 million fragments in the libraries. After years of work, exchange visits between laboratories and at a cost of millions of Euros, the combined efforts of British and French researchers have reduced the complex genetics of wheat to two large freezers full of tiny test-tubes. Pooling the British and French research efforts has had two major benefits. Firstly, it has dramatically shortened the time taken to produce a complete gene library. Secondly, it has resulted in several slightly different libraries, providing the researchers with some additional information not available from a single library.
“The USA would like a copy of the British/French library and China, Japan, and Australia have expressed interest in using it” says Dr Boulos Chalhoub (project leader at INRA). “This shows just how valuable a resource we have developed and in time we expect to see these libraries helping researchers and breeders in their continuing pursuit of both global food security and environmentally sustainable agriculture. We would like to see this collaboration set the pattern for the future, with major international cooperative efforts on a wide variety of crops, developing genetic resources that are openly accessible to academic and commercial organisations”.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
