Five years ago, we reported that a dolphin recognizes himself when it sees its image in a mirror. Now it has been discovered that elephants do too. Scientists think that this is a true test of self-awareness.

Peter Aldhous writes in New Scientist that recognizing your own image was thought to be something only humans were capable of. Those of us who have pets know that when a cat or dog sees itself in a mirror, it thinks that another animal is there and will sometimes try to attack it. People who have a single bird as a pet will often put a mirror in the cage so that the bird thinks there?s another bird there, keeping it company.

Researcher Cameron Wake says, “The very notion of the Northeast as we know it is at stake. The near-term emissions choices we make in the Northeast and throughout the world will help determine the climate and quality of life our children and grandchildren experience.”

He quotes German researcher Dietmar Glindemann as saying, “That we are smelling the metal itself is actually an illusion? That humans can ‘smell’ iron can be interpreted as a sense for the smell of blood.”

Glossolalia, otherwise referred to as “speaking in tongues,” has been around for thousands of years, and references to it can be found in the Old and New Testament. The person appears to be speaking in an incomprehensible language, yet perceives it to have great personal meaning. Now scientists are attempting to explain what actually happens to the brain of someone when this happens. Researchers at the University of Pennsylvania School of Medicine have discovered decreased activity in the frontal lobes, an area of the brain associated with self control.read more
