  • Bio and Medicine

The stickleback fish, Gasterosteus aculeatus, is one of the most thoroughly studied organisms in the wild, and has been a particularly useful model for understanding variation in physiology, behavior, life history and morphology caused by different ecological situations in the wild.

Animals of the American West – Yellowstone National Park (Part 2)

Tree – elk – wolf – tree. Sounds like a simple ecological system, right? In Yellowstone National Park, however, it's a balance that park rangers are doing their best to manage and maintain. Just as in any place, species depend upon one another to survive. And the reintroduction of wolves to the park has been a very controversial topic.

Singing to females makes male birds' brains happy

  • Animals
  • Brain and Behavior

The melodious singing of birds has been long appreciated by humans, and has often been thought to reflect a particularly positive emotional state of the singer. In a new study published in the online, open-access journal PLoS ONE on October 1, researchers at the RIKEN Brain Science Institute in Japan have demonstrated that this can be true. When male birds sang to attract females, specific "reward" areas of their brain were strongly activated.

Models of eel cells suggest electrifying possibilities

  • Animals
  • Bio and Medicine
  • Physics and Numbers

Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper takes it to a cellular level. Applying modern engineering design tools to one of the basic units of life, they argue that artificial cells could be built that not only replicate the electrical behavior of electric eel cells but in fact improve on them.
