Study identifies a genetic risk factor for persistent pain
A new study is the first to identify a genetic risk factor for persistent pain after traumatic events and indicates that mechanisms influencing chronic pain development may be related to the stress response, rather than any specific injury caused by the traumatic event.

Individual donation amounts drop when givers are in groups
In December of last year the New York Post published images of a man about to be killed by a train while several bystanders did little to help him. Numerous studies have provided evidence that people are less likely to help when in groups, a phenomenon known as the bystander effect. Those studies examined situations where only one person was needed to take action to help another. A University of Missouri anthropologist recently found that even when multiple individuals can contribute to a common cause, the presence of others reduces an individual's likelihood of helping. This research has numerous applications, including possibly guiding the fundraising strategies of charitable organizations.

The equine Adam lived fairly recently: Close relationships among modern stallions
In mammals, an individual's sex is determined by the chromosomes it inherits from its parents. Two X chromosomes lead to a female, whereas one X and one Y lead to a male. Y chromosomes are only passed from fathers to sons, so each Y chromosome represents the male genealogy of the animal in question. In contrast, mitochondria are passed on by mothers to all their offspring. This means that an analysis of the genetic material or DNA of mitochondria can give information on the female ancestry. For the modern horse, it is well known that mitochondrial DNA is extremely diverse and this has been interpreted to mean that many ancestral female horses have passed their DNA on to modern horse breeds. Until recently, though, essentially no sequence diversity had been detected on the Y chromosome of the domestic horse. Not only does the lack of sequence markers on the Y chromosome make it impossible to trace male lineages with confidence, it also represents a scientific paradox. How can a species with so many female lines have so few male lines? The issue has now been addressed by Barbara Wallner and colleagues at the Institute of Animal Breeding and Genetics, University of Veterinary Medicine, Vienna (Vetmeduni Vienna).
