A colorful gathering of middle-aged stars

NGC 3532 is a bright open cluster located some 1300 light-years away in the constellation of Carina(The Keel of the ship Argo). It is informally known as the Wishing Well Cluster, as it resembles scattered silver coins which have been dropped into a well. It is also referred to as the Football Cluster, although how appropriate this is depends on which side of the Atlantic you live. It acquired the name because of its oval shape, which citizens of rugby-playing nations might see as resembling a rugby ball.

The results could be of use in promoting decision skills in difficult decisions.

Study unlocks basis of key immune protein's two-faced role

A Brigham and Women's Hospital-led team has identified a long sought-after partner for a key immune protein, called TIM-3, that helps explain its two-faced role in the immune system—sometimes dampening it, other times stimulating it. This newly identified partner not only sheds light on the inner workings of the immune system in diseases such as HIV, autoimmunity, and cancer, but also provides a critical path toward the development of novel treatments that target TIM-3. The researcher's findings appeared last month in the journal Nature.

Why do people with autism see faces differently?

The way people with autism spectrum disorder (ASD) gather information - not the judgement process itself - might explain why they gain different perceptions from peoples' faces, according to a new study from Hôpital Rivière-des-Prairies and the University of Montreal. "The evaluation of an individual's face is a rapid process that influences our future relationship with the individual," said Baudouin Forgeot d'Arc, lead author of the study. "By studying these judgments, we wanted to better understand how people with ASD use facial features as cues. Do they need more cues to be able to make the same judgment?"
