- The International Cancer Genome Consortium (ICGC) was launched to coordinate large-scale cancer genome studies in tumours from 50 different cancer types and/or subtypes that are of clinical and societal importance across the globe. Systematic studies of more than 25,000 cancer genomes at the genomic, epigenomic and transcriptomic levels will reveal the repertoire of oncogenic mutations, uncover traces of the mutagenic influences, define clinically relevant subtypes for prognosis and therapeutic management, and enable the development of new cancer therapies.

- A magnetic vortex confined in a magnetically soft ferromagnet with micron-sized dimensions possesses a characteristic dynamic excitation known as a translational mode that corresponds to spiral-like precession of the vortex core around its equilibrium position. We report micromagnetic modeling and experimental detection using a microwave reflection technique of the magnetic field tunability of this mode in 40 nm thick, 3x1.5 mu m(2) and 2x1 mu m(2) permalloy ellipses. At remanence the translational modes are detected at 77 and 118 MHz. The frequency shows a strongly anisotropic dependence on magnetic field applied in the plane of the ellipse. The frequencies more than double when a static field is applied along the hard (short) axis, whereas they are almost field-independent when the field is aligned with the easy (long) axis. Micromagnetic calculations reveal that the observed behavior is governed by the shape of the energy potential well that is influenced mainly by magnetostatic and Zeeman energies.
