Invasion and metastasis are the most deadly hallmarks of cancer. Once a cancer has acquired the ability to colonize new sites in the body it becomes dramatically more difficult to treat. This has made it a focus of much of cancer research. The humble fruit fly, Drosophila mela- nogaster, has despite its relative simplicity, made significant contributions to the understanding of tumor progression. In this review we outline and highlight those with an emphasis on modeling the genetic and epigenetic changes required for invasion and metastasis. We will revisit the early years of cancer modeling in Drosophila where the first parallels were drawn between Drosophila and vertebrate neoplasms and highlight recent advances using genetic screens and interactions with the epithelial microenvironment and innate immune system. We focus on the power and limitations of current fly models of metastasis.

In this work we have conducted a study on the radiative and spectroscopic properties of the radiative precursor and the post-shock region from experiments with radiative shocks in xenon performed at the Orion laser facility. The study is based on post-processing of radiation-hydrodynamics simulations of the experiment. In particular, we have analyzed the thermodynamic regime of the plasma, the charge state distributions, the monochromatic opacities and emissivities, and the specific intensities for plasma conditions of both regions. The study of the intensities is a useful tool to estimate ranges of electron temperatures present in the xenon plasma in these experiments and the analysis performed of the microscopic properties commented above helps to better understand the intensity spectra. Finally, a theoretical analysis of the possibility of the onset of isobaric thermal instabilities in the post-shock has been made, concluding that the instabilities obtained in the radiative-hydrodynamic simulations could be thermal ones due to strong radiative cooling.
