Some people live their lives by the motto "no risk - no fun!" and avoid hardly any risks. Others are clearly more cautious and focus primarily on safety when investing and for other business activities. Scientists from the University of Bonn in cooperation with colleagues from the University of Zurich studied the attitudes towards risk in a group of 56 subjects.

Maintaining a healthy body weight may be difficult for many people, but it's reassuring to know that our brains and bodies are wired to work together to do just that—in essence, to achieve a phenomenon known as energy balance, a tight matching between the number of calories consumed versus those expended. This careful balance results from a complex interchange of neurobiological crosstalk within regions of the brain's hypothalamus, and when this "conversation" goes awry, obesity or anorexia can result.

Anxiety disorders affect approximately 40 million American adults each year, and although they are treatable, they often cause significant distress. The excessive fear and dread that accompanies anxiety disorders clearly influences the everyday decision-making processes of anxious individuals. Despite its importance, “there is surprisingly little research on how anxiety disorders influence decisions,” commented neuroscientist Dr. Elizabeth Phelps, who co-authored this new review with Dr. Catherine Hartley, both of New York University.

Researchers from the Institute of Psychiatry at King’s College London have found a relationship between molecular tags on our DNA and the weight of a particular region of the human brain called the cerebellum. The findings may provide important clues for understanding the causes of schizophrenia and autism.

The notion of a pain switch is an alluring idea, but is it realistic? Well, chemists at LMU Munich, in collaboration with colleagues in Berkeley and Bordeaux, have now shown in laboratory experiments that it is possible to inhibit the activity of pain-sensitive neurons using an agent that acts as a photosensitive switch. For the LMU researchers, the method primarily represents a valuable tool for probing the neurobiology of pain.

New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging, reveal a novel mechanism through which the brain may become more reluctant to function as we grow older.
