Como en un espejo by Ingmar Bergman

Ernst Ingmar Bergman was a nine-time Academy Award-nominated Swedish film, stage, and opera director. He depicted bleakness and despair as well as comedy and hope in his explorations of the human condition. He is recognized as one of the greatest and most influential filmmakers in cinematic history.

He directed 62 films, most of which he wrote, and directed over 170 plays. Some of his internationally known favorite actors were Liv Ullmann, Bibi Andersson, and Max von Sydow. Most of his films were set in the stark landscape of his native Sweden, and major themes were often bleak, dealing with death, illness, betrayal, and insanity.

Bergman was active for more than 60 years, but his career was seriously threatened in 1976 when he suspended a number of pending productions, closed his studios, and went into self-imposed exile in Germany for eight years following a botched criminal investigation for alleged income tax evasion.

Until now. A team of scientists at the University of Texas at Austin has found the first sensor of our magnetic field in the brain of a small worm, called C. The sensor is microscopic and sits at the end of a neuron. The researchers surmise that this structure likely also exists in other animals as well. So, taking this knowledge, they collected worms from around the world.

Most people think of migration as the seasonal movement of a flock of birds between their breeding and non-breeding sites.

Migratory animal species navigate their journey using a variety of methods. By Susan Blackmore. Some birds, fish, turtles and whales travel enormous distances when migrating to find food or to mate. The furthest may be the bar-tailed godwit, flying over 10,km from New Zealand to Alaska. By contrast, mallards can find north using the stars, an ability that is genetically programmed. Other animals use land features such as mountain ranges and rivers, and dolphins use the shape of the ocean floor. Wildebeest follow the scent of rain and salmon use smell to return to the very same stream where they were born.
