Journal Club: Neural circuits and social status spur zebrafish to swim or flee

Should I stay or should I go? In the zebrafish (Danio rerio), two competing neural circuits determine whether an animal swims or turns tail and escapes. Social status can tip the balance between these circuits, leading dominant and subordinate animals … Continue reading

Journal Club: Fruit fly hybrids make poor foragers, offering insight into how species remain distinct

  When one fruit fly species meets another, they sometimes interbreed. And yet despite this genetic mixing, distinct species still persist—over 2,000 of them. Evolutionary biologist Daniel Matute of the University of North Carolina at Chapel Hill is one of … Continue reading

Journal Club: Even in honeybees, early aggression makes for angry adults

A childhood of violence can make humans and other animals violent later on. Now scientists unexpectedly find the same holds true for even the simple honeybee. Unlike people, however, greater aggression in honeybees was not associated with later health problems. … Continue reading

Selfless decisions linked with reduced depression in teenagers

Life is dangerous as a teenager. At the same time as we’re learning to drive, we’re prone to risker behavior and more likely to make impulsive decisions than when we are children or adults. Neurologists have noticed that a small … Continue reading

Predicting cooperative behavior from genes

If only the fittest members of a species survive, then cooperative behavior doesn’t make sense. It is costly to individuals and benefits others. Over the past few years, however, many researchers have shown how cooperative behavior plays nicely with evolutionary … Continue reading
