A new method to mine existing scientific data may provide a wealth of information about the interactions among genes, the environment and biological processes, say researchers at the Stanford University School of Medicine, Lucile Packard Childrens Hospital and Harvard Medical School. Like panning for gold, they used the powerful technique to sift through millions of bits of unrelated information - in this case, gene expression data from so-called microarray experiments - to pinpoint genes likely to be involved in leukemia, aging, injury and muscle development.
"This is just the tip of the iceberg," said bioinformatics specialist Atul Butte, MD, PhD, who is also a pediatrician at Lucile Packard Childrens Hospital at Stanford. "Nearly 100 different diseases have been studied using microarrays, spanning all of medicine. This is a new way to explore this type of data. We can study virtually everything thats been studied." Butte is the first author of the study, which is published in the Jan. 6 online issue of Nature Biotechnology.
The advance comes with a caveat, however: clinically useful nuggets will be buried under the avalanche of data inundating international repositories each year unless scientists come up with a way to better classify their experiments and results.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
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...
