Signals from the Atlantic salmon highway
For years scientists have struggled to understand the decline and slow recovery of Atlantic salmon, a once abundant and highly prized game and food fish native to New England rivers. Biologists agree that poor marine survival is affecting salmon in the U.S. and Canada, but specific causes are difficult to determine in the ocean. Small acoustic tags and associated technology may provide some answers.

Toy-Like Microboat Could Carry Tiny Cargoes
As a child, Cheng Luo, an engineer from the University of Texas at Arlington, recalls playing with wooden toy boats that were propelled forward when a drop of oil was placed on the back of the boats. When the oil slid off into the water, it created lower surface tension behind the boat than in front, which pushed the boat forward. This surface-tension-based propulsion is called the Marangoni effect.
