Harnessing genomic information for livestock improvement.

The world demand for animal-based food products is anticipated to increase by 70% by 2050. Meeting this demand in a way that has a minimal impact on the environment will require the implementation of advanced technologies, and methods to improve the genetic quality of livestock are expected to play a large part. Over the past 10 years, genomic selection has been introduced in several major livestock species and has more than doubled genetic progress in some. However, additional improvements are required. Genomic information of increasing complexity (including genomic, epigenomic, transcriptomic and microbiome data), combined with technological advances for its cost-effective collection and use, will make a major contribution

The opportunities for and obstacles against prevention: the example of Germany in the areas of tobacco and alcohol

Background: Recent years have seen a growing research and policy interest in prevention in many developed countries. However, the actual efforts and resources devoted to prevention appear to have lagged well behind the lip service paid to the topic. Discussion: We review the evidence on the considerable existing scope for health gains from prevention as well as for greater prevention policy efforts in Germany. We also discuss the barriers to "more and better" prevention and provide modest suggestions about how some of the obstacles could be overcome. Summary: In Germany, there are substantial health gains to be reaped from the implementation of evidence-based, cost-effective preventive interventions and policies. Barriers to more prevention include social, historical, political, legal and economic factors. While there is sufficient evidence to scale up prevention efforts in some public health domains in Germany, in general there is a comparative shortage of research on non-clinical preventive interventions. Some of the existing barriers in Germany are at least in principle amenable to change, provided sufficient political will exists. More research on prevention by itself is no panacea, but could help facilitate more policy action. In particular, there is an economic efficiency-based case for public funding and promotion of research on non-clinical preventive interventions, in Germany and beyond, to confront the peculiar challenges that set this research apart from its clinical counterpart
