Anthropologist examines the motivating factors behind hazing It happens in military units, street gangs and even among athletes on sports teams. In some cultures, the rituals mark the transition from adolescence to adulthood. And in fraternities and sororities, it's practically a given. With a long history of seemingly universal acceptance, the practice of hazing is an enduring anthropological puzzle.

Changes in epigenetic DNA functions links diabetes predisposition to Alzheimer's disease Diabetes and dementia are rising dramatically in the United States and worldwide. In the last few years, epidemiological data has accrued showing that older people with diabetes are significantly more likely to develop cognitive deterioration and increased susceptibility to onset of dementia related to Alzheimer's disease.
Multiple ssclerosis: Functional change in brain as cause of cognitive disorders Over the course of the disease, multiple sclerosis is very often combined with a deteriorating memory and attention deficits. Researchers have now demonstrated by means of a meta-analysis of functional image data that increased activations in the involuntary attention system in the brain are responsible for these disorders in MS patients.
People tend to communicate with similar people, even more than previously thought People's tendency to communicate with similar people is stronger than earlier believed, which restricts the flow of information and ideas in social networks.
Super song learners: Mechanism for improving song learning in juvenile zebra finches uncovered Most songbirds learn their songs from an adult model, mostly from the father. However, there are relatively large differences in the accuracy how these songs are copied. Researchers have now found in juvenile zebra finches a possible mechanism that is responsible for the differences in the intensity of song learning. They provided the nerve growth factor "BDNF" to the song control system in the brain. With this treatment the learning ability in juvenile males could be enhanced in such a way that they were able to copy the songs of the father as good as it had been observed in the best learners in a zebra finch nest.
A trace of memory, explored Most of our behavior – and thus our personality – is shaped by previous experience. To store the memory of these experiences and to be able to retrieve the information at will is therefore considered one of the most basic and important functions of the brain. The current model in neuroscience poses that memory is stored as long-lasting anatomical changes in synapses, the specialized structures by which nerve cells connect and signal to each other.

Genetic variation alters efficacy of antidepressant Having a different form of a gene that regulates the brain chemical noradrenaline influences how well men remember negative memories after taking the antidepressant drug reboxetine, according to a study. The findings demonstrate how genes can influence antidepressant response.
Delaying gratification, when the reward is under our noses How can some people resist the attraction of immediate pleasures and pursue long-term goals, while others easily succumb and compromise their ultimate expectations? A recent study has found that the brain's memory systems help in resisting temptations. One factor which might explain the difference in people's ability to resist temptation might lie in the activity of a deep brain structure: the hippocampus.
Baby's innate number sense predicts future math skill A new study suggests that the strength of an infant's innate sense of numerical quantities can be predictive of that child's mathematical abilities three years later.
