Dogs' social skills linked to oxytocin sensitivity
The tendency of dogs to seek contact with their owners is associated with genetic variations in sensitivity for the hormone oxytocin, according to a new study. The results contribute to our knowledge of how dogs have changed during their development from wolf to household pet.

Genomic recycling: Ancestral genes take on new roles
One often hears about the multitude of genes we have in common with chimps, birds or other living creatures, but such comparisons are sometimes misleading. The shared percentage usually refers only to genes that encode instructions for making proteins -- while overlooking regulatory genes, which nonetheless make up a large part of the genome.

Sheep gene insights could help farmers breed healthier animals
Fresh insights into the genetic code of sheep could aid breeding programs to improve their health and productivity. Scientists have now mapped which genes are turned on and off in the different tissues and organs in a sheep's body.

More efficient use of raw materials with the aid of 'molecular conveyor belts'
Making valuable products, such as fuels, synthetic materials or pharmaceuticals, from renewable raw materials is to date not efficient enough because the microorganisms used only process the raw materials very slowly and generate many by-products in addition to the substances actually wanted. Biotechnologists have now succeeded in optimizing sugar utilization in baker's yeast.

Cells programmed like computers to fight disease
Cells can be programmed like a computer to fight cancer, influenza, and other serious conditions -- thanks to a breakthrough in synthetic biology.

Membrane vesicles released by bacteria may play different roles during infection
Bacteria release membrane-derived vesicles (MVs), which are small particles that can transport virulence factors to neighboring bacteria or to the cells of a mammalian host. This special MV-based system for delivering toxic proteins and nucleic acids in a protected manner to the target cells may have different specific functions depending on whether the bacterium acts as an extracellular or intracellular pathogen.

Innate immunity: To operate, insert dimers
The presence of DNA in mammalian cell cytoplasm triggers an immune response by binding to a dimeric enzyme, which inserts between DNA double helices to form the “rungs” of a ladder-like structure, as an LMU team has now shown.

Secrets of Bonsai: Uncovering the mechanism of root regeneration
The molecular mechanism behind root regeneration after root cutting in plants has been discovered. A finding which could lead to the development of new methods for regulating plant growth in agriculture and horticulture.
