Sunspot magnetic fields are dropping by about 50 gauss per year. If we extrapolate this trend into the future, sunspots could completely vanish around the year 2015.

Long before the broomstick became popular with witches in medieval Europe, the flying carpet was being used by thieves and madmen in the Orient. ... In the Ben Sherira chronicle, certain passages describe the workings of a flying carpet. Unfortunately, much of the vocabulary used in these parts is indecipherable, so little has been understood about their method of propulsion. What is understood is that a flying carpet was spun on a loom...

Researchers have discovered a magnetic equivalent to electricity: single magnetic charges that can behave and interact like electrical ones. The work is the first to make use of the magnetic monopoles that exist in special crystals known as spin ice.

Scientists have managed to push back the date for the earliest known presence of a magnetic field on Earth by about 250 million years. The evidence is seen in tiny iron minerals that are aligned inside ancient dacite rocks from the Barberton mountains in South Africa.

Over a 1000-km run, superconducting cables can carry far more power than cables of a comparable size. Even taking into account the energy required to cool them, they lose just a third as much energy in transmission. Just as in the case of optical fibres, the technology has been quietly refined over the years and in some senses is ready to be deployed. This will be costly at first, but with tangible benefits that the wider market may just...

Humankind's most distant emissaries are flying through a turbulent sea of magnetism as they seek to break free of our Solar System. Nasa's Voyager probes, which were launched in 1977, are now approaching the very edge of our Sun's influence, more than 14 billion km from Earth; and they are still returning data. That information has allowed scientists to build a better picture of what conditions are like in the zone where...

A light-sensitive protein in the human eye has been shown to act as a "compass" in a magnetic field, when it is present in flies' eyes. The study in Nature Communications showed that without their natural "magnetoreception" protein, the flies did not respond to a magnetic field - but replacing the protein with the human version restored the ability. Despite much controversy, no conclusive evidence exists that...
