Every family unit is a complex social network
influenced by numerous inputs. In nature, social organizations at the family and small-group level can range from violent to peaceful, monogamous to polyandrous, segregated to sharing work. On Wednesday August 4, 2004, scientists will gather for th...

Study reveals evolution on the (butterfly) wing
... We can also trace the origin of the line and spot network
to some time after the evolutionary split of moths and butterflies. "These gene expression patterns give us a good model of how a character can evolve, switching between two states, in this case a line and a spot," Reed continued. "This study prov...
New study in moths shows insects not entirely ruled by instinct

Brain serotonin enzyme finding might explain psychiatric disorders

of billions of cells called neurons. When stimulated, neurons fire, sending a wave of electrical charge from one end to the other. To bridge the gap between nerves, the neurons release chemical neurotransmitters, including serotonin, that set off an ...

of motions that make a protein enzyme act as a whole. We are proposing for the first time that this also happens with RNA enzymes." Getting a grasp on how ribozymes work is important for answering fundamental questions of biology, Walter said, but th...
