An anonymous reader writes: The nature of dark matter has been debated for years. Now, some scientists believe they know how dark matter really acts. They've suggested that most of the matter in the universe may be made out of particles that possess an unusual, doughnut-shaped electromagnetic field called an anapole, which means that dark matter would be endowed with a rare form of electromagnetism. In the past, several physicists have suggested that dark matter is made from Majorana fermion particles. Yet while this particle was predicted in the 1930s, it's stubbornly resisted detection. The new study also suggests that dark matter is made out of these particles, but this time the scientists may have some proof.
