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
