Scientists studying human Swedish twins and voles have discovered a gene variant involved in producing a hormone that affects monogamy in animals whereby men with two copies of the variant were twice as likely to have had a relationship crisis with their spouse or partner in the last 12 months than men who did not carry the variant.

Yeast, the essential microorganism for fermentation in the brewing of beer, converts carbohydrates into alcohol and other products that influence appearance, aroma, and taste. In a study published online in Genome Research researchers have identified the genomic origins of the lager yeast Saccharomyces pastorianus, which could help brewers to better control the brewing process.

Treatments that ramp up production of the tiny "motors" that power cells may have promise for treating one of the most common forms of inherited neuromuscular disease, according to a report in the September Cell Metabolism, a Cell Press publication. Neuromuscular disorders caused by defects in those mitochondrial motors affect a large number of children and adults worldwide, but today remain without treatment, the researchers said.

Genetic Covariation Between Effectiveness And Cost Of Defence In Aphids

Why are not all hosts resistant to their parasites? Possibly, because the necessary defences are costly. Evolutionary biologists distinguish between long-term, evolutionary costs of possessing defences against parasites, and the short-term costs of using them. Yet they typically focus on the former in the search for constraints on the evolution of resistance. This article shows that short-term costs may be of equal evolutionary importance.
