Genetic analysis of Antarctic fur seals, alongside decades of in-depth monitoring, has provided unique insights into the effect of climate change on a population of top-predators. Published in Nature this week, the findings show that the seals have significantly altered in accordance with changes in food availability that are associated with climate conditions. Despite a shift in the population towards 'fitter' individuals, this fitness is not passing down through generations, leaving the population in decline.

Prof. Ruedi Fries and Dr. Hubert Pausch monitor sequence data of breeding cattle.
An international collaboration known as the '1000 Bull Genomes Project' aims to accelerate breeding for desired traits in beef and dairy cattle while also improving animal health and welfare. Results of the project's first phase -- based on sequencing the whole genomes of 234 individual bulls whose direct descendants number in the tens of millions -- are reported in the journal Nature Genetics.

Researchers at the BBSRC-funded Babraham Institute, in collaboration with the Wellcome Trust Sanger Institute Single Cell Genomics Centre, have developed a powerful new single-cell technique to help investigate how the environment affects our development and the traits we inherit from our parents. The technique can be used to map all of the 'epigenetic marks' on the DNA within a single cell. This single-cell approach will boost understanding of embryonic development, could enhance clinical applications like cancer therapy and fertility treatments, and has the potential to reduce the number of mice currently needed for this research.

The genetic blueprint is an invaluable resource to plant science researchers and breeders. For the first time, they have at their disposal a set of tools enabling them to rapidly locate specific genes on individual wheat chromosomes throughout the genome. Jorge Dubcovsky, Professor at the University of California Davis, USA, says that these results "have been a fantastic resource for our laboratory. The development of genome specific primers, which used to take several weeks of work, can now be done in hours. Mapping of any sequence to the specific chromosome arm can now be done in silico in minutes. In addition to the acceleration of day to day work in wheat genetics, this resource has made possible analyses and discoveries at the genome level that were not possible before."

Two transcription factors are all that is required to make blood from pluripotent stem cells.
The ability to reliably and safely make in the laboratory all of the different types of cells in human blood is one key step closer to reality.

CRISPR, a system of genes that bacteria use to fend off viruses, is involved in promoting antibiotic resistance in Francisella novicida, a close relative of the bacterium that causes tularemia. The finding contrasts with previous observations in other bacteria that the CRISPR system hinders the spread of antibiotic resistance genes.

This is an image of the inflorescence of Arabidopsis thaliana.
In close collaboration with Jürg Schönenberger and Yannick Städler from the Department of Botany and Biodiversity Research of the Faculty of Life Sciences, University of Vienna, 14 developmental stages of the flower of Arabidopsis thaliana from very early meristematic floral initiation to fully developed seeds were monitored with micro-computed tomography in 3D. From the same set of developmental stages a full metabolic profile using mass spectrometry was measured covering hundreds of biochemical pathways.

An international team of researchers, including scientists from the Max Planck Institute for Medical Research in Heidelberg, has just a reported a major step in understanding photosynthesis, the process by which the Earth first gained and now maintains the oxygen in its atmosphere and which is therefore crucial for all higher forms of life on earth.
