    An End to the Winter Blues?

    Is the long winter bringing you down? Do TV and comfort food sound better than going out? If so, you might be among the 11 million Americans who get the winter blues. Remedies for seasonal depression are limited – but happily, the Weizmann Institute is working hard to shine light on depression's many causes, offering the hope of new, improved treatments.

    Bats Offer New Directions in Brain Research

    Dr. Nachum Ulanovsky is gaining fresh insight on memory and the brain, thanks to a novel research subject: the bat. Free-flying and with excellent memories, bats could provide new understanding of a range of neurological conditions, such as Alzheimer's.

    The Autism Puzzle: What the Weizmann Institute is Doing to Solve It

    The CDC estimates that 1 in 68 children has autism, and identifying its complex causes is difficult. Fortunately, Weizmann Institute researchers are approaching autism from a number of fresh directions – such as smell and light – in order to piece together its puzzle and develop new means of early diagnosis and better therapies.

    Mice in a ""Big Brother"" Setup Develop Social Structures

    How does a social animal gain dominance over its fellows? With a unique setup, Weizmann scientists were able to closely study mice living in almost-natural conditions and observe regulation of social behavior, including selection of a leader. This work could also provide insight into the social aspects of schizophrenia and autism.

    Stress-Coping Mechanism Helps Mice Make New Friends

    What makes us reluctant or willing to leave our social comfort zones? Prof. Alon Chen and his team in the Department of Neurobiology found that a molecule that helps the brain cope with stress appeared to act as a ""social switch"" in mice, causing them to either increase interactions with ""friends"" or seek to meet ""strangers."" Since a similar system exists in the human brain, the findings may help explain why some people are better at making new friends, and shed light on the social difficulties experienced by those with autism, schizophrenia, and more.
