University of Toronto microbiologists have used pattern recognition software to discover the function of yeast genes essential to cell life - knowledge that could help scientists determine what causes cells to die, as well as what they need to live.
"Given the similarities between the yeast and human genomes, our work should promote advances in genomics research in both yeast and humans," said Professor Timothy Hughes of U of T’s Department of Medical Genetics and Microbiology, who led the research team.
A paper published in the July 9 issue of the journal Cell describes how the researchers engineered mutations to 700 of the 1,000 yeast genes that are essential to cell life. They analyzed the mutant strains by making several basic measurements -- cell size, cell shape and gene levels - and by evaluating a cell’s potential to grow in a variety of media. They then took these data and did computerized analysis of entire categories of genes in order to predict the functions of individual genes, applying a standard technique for pattern discovery used in fields ranging from marketing to face recognition.

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...
