Recent advances in understanding links between genes and the susceptibility to particular diseases have considerably increased the scope for predictive diagnosis. Methods. We analyse how the introduc- tion of predictive diagnosis affects patients�decisions to undergo medical screenings relying on a �rational choice�model. Findings. We show that predictive diagnosis can increase the number of fatalities from a deadly disease. Interpretation. Our result shows the necessity of careful further analysis and debate about the pros and cons of predictive diagnosis and the publication of medical research in general

Impact of Neutron Decay Experiments on non-Standard Model Physics

This paper gives a brief overview of the present and expected future limits on physics beyond the Standard Model (SM) from neutron beta decay, which is described by two parameters only within the SM. Since more than two observables are accessible, the problem is over-determined. Thus, precise measurements of correlations in neutron decay can be used to study the SM as well to search for evidence of possible extensions to it. Of particular interest in this context are the search for right-handed currents or for scalar and tensor interactions. Precision measurements of neutron decay observables address important open questions of particle physics and cosmology, and are generally complementary to direct searches for new physics beyond the SM in high-energy physics. Free neutron decay is therefore a very active field, with a number of new measurements underway worldwide. We present the impact of recent developments.Comment: 13 pages, 6 figures; Proceedings of the 5th International BEYOND 2010 Conference, Cape Town, South Africa (2010), World Scientific, accepted for publication; Corrected typo
