Electrical engineers are starting to consider materials made from organic molecules -- including those made from carbon atoms -- as an intriguing alternative to the silicon and metals used currently in electronic devices, since they are easier and cheaper to produce. A RIKEN-led research team has now demonstrated the origin of magnetism in organic molecules, a property that is rarely found in this class of material, but is vital if a full range of organic electronic devices is to be created.

(PhysOrg.com) -- The transition-metal monoxide FeO is an archetypal example of a Mott insulator—a material that should conduct electricity under conventional band theories but becomes an insulator when measured, especially at low temperatures—and a major iron-bearing component of the Earth’s interior. Understanding the high-pressure behavior of this material is important for both solid-state physics and Earth science.

Here's a great video primer on how auroras form, from Per Byhring and the physics department at the University of Oslo. With wonderful graphics, the nearly five-minute-long video details the origin of the solar storms that trigger the Northern and Southern lights

The human eye is an exquisitely complicated organ. It acts like a camera to collect and focus light and convert it into an electrical signal that the brain translates into images. But instead of photographic film, it has a highly specialized retina that detects light and processes the signals using dozens of different kinds of neurons

The year was 1848. a young British naturalist named Henry Walter Bates had gone to the Amazon with fellow countryman Alfred Russel Wallace to look for evidence of the origin of species. Over the course of his 11-year stay, he noticed that local relatives of a European butterfly known as the cabbage white--the pierids--were bedecked in the showy reds and yellows of rain forest butterflies called heliconids
