Ruminants are a diverse group of mammals that includes families such as deer, cows, and goats. A large number of ruminant genomes were sequenced, and data analysis show large population reductions are coinciding with the migration of humans out of Africa. Also, authors found evidence for selection on cancer-related genes that may function in antler development in deer, and identified the genetic basis of adaptations that allow reindeer to survive in the harsh conditions of the Arctic.

|Improving Accuracy in Variant Genotyping |
Genotype estimates from short-read sequencing data are typically based on the alignment of reads to a linear reference, but reads originating from more complex variants often align poorly, resulting in biased genotype estimates. Here, we present a new method to efficiently perform unbiased, probabilistic genotyping across the variation spectrum. We also demonstrate that including a variation-prior database containing already known variants significantly improves sensitivity. Adapted from abstract.

|Greenlandic Genetic Variation|
We show that a genetic mutation substantially increases the risk of type 2 diabetes for individuals who carry two copies of it. The mutation is common in native Greenlanders; hence, our finding has great potential to lead to better treatment of diabetes in this population.

We describe the construction of a reference genome based on high-coverage sequencing and de novo assemblies of 150 individuals with mate-pair libraries extending up to 20 kilobases. The reference genome is expected to strongly benefit precision medicine initiatives.

We present a collection of active enhancers instrumental in the pursuit to understand regulation of differentiation and homeostasis, as these enhancers control temporal and cell-type-specific activation of gene expression in multicellular eukaryotes. We also present a comprehensive map over mammalian transcription start sites and their usage in human and mouse primary cells, cell lines and tissues. The functional annotation of mammalian cell-type-specific transcriptomes has wide applications in biomedical research.

|Bayesian Methods in Structural Bioinformatics|
This is the first field-defining book on Bayesian methods in structural bioinformatics. The book provides an introduction to Bayesian statistics and concepts in machine learning and statistical physics. Chapters include describtion of state-of-the-art statistical methods in structural bioinformatics with a particular focus on statistical methods that have a clear interpretation in the framework of statistical physics.

|Probabilistic Protein Structure Prediction|
Protein structure prediction requires efficient probabilistic exploration of the structural space that correctly reflects the relative conformational stabilities. We have developed a fully probabilistic, continuous model of local protein structure in atomic detail. The model represents a significant theoretical and practical improvement over the widely used fragment assembly technique. Adapted from abstract.

|Probabilistic Models of Proteins and Nucleic Acids|
In this landmark textbook, authors describe probabilistic models used in large-scale sequence analysis. Examples are hidden Markov models used for analysing biological sequences, linguistic-grammar-based probabilistic models used for identifying RNA secondary structure, and probabilistic evolutionary models used for inferring phylogenies of sequences from different organisms.
