Some animals display very human behaviors: chimps grieve, rats love to be tickled, and moths remember living as caterpillars.
Science journalist Virginia Morell explores the complex minds of animals in her new book, "Animal Wise." From field sites to laboratories, Morell shows how animal cognition research has evolved, and how animals possess traits many feel are unique to humans.
She spoke at the Elliott Bay Book Company on April 8, 2013.

For years, PTSD — or post-traumatic stress disorder — has been an issue for military members returning from Iraq and Afghanistan.
But humans aren't the only ones with problems. Military dogs returning from war zones are also showing signs of PTSD. And there's evidence that these canines need some extra tender loving care after their tours of duty.
Ultraviolet (false color). Bees and other pollinators can see the ultraviolet end of the spectrum. They are guided by patterns on flowers that are invisible to humans.

Fragrance plume (artist's depiction). Bees follow specific odors to locate flowers and, once they arrive, use scent maps to move toward the center of the flower. Fragrance that clings to a bee provides information for other bees back at the hive.

Visible spectrum. Certain bright colors and petal shapes attract certain pollinators.
Flowers are nature's ad men. They'll do anything to attract the attention of the pollinators that help them reproduce. That means spending precious energy on bright pigments, enticing fragrances and dazzling patterns.
Now, scientists have found another element that contributes to flowers' brand: their distinct electric field.
Anne Leonard, who studies bees at the University of Nevada, says our understanding of pollinator-flower communication has been expanding for decades.
People in the Northwest are among the most likely in the nation to have pets. That's according to a new survey by the American Veterinary Medical Foundation. Washington, Oregon and Idaho rank in the top 10 for pet-owning households — with Oregon at No. 4, Washington at No. 6 and Idaho at No. 9. Maybe you’re one of the Northwest’s many pet people. If you are, you know that owning a dog can be e lot of work. But what if you had help? Free help. Sound too good to be true? According to Eric Husk it isn’t. He is the founder of City Dog Share, which he describes as a dog-sitting co-op. Ross Reynolds gets the details.
