Forgotten Data From 1996 Sheds New Light on Jupiter’s Mysterious Moon Ganymede

Twenty-two years ago, the Galileo spacecraft made its first flyby of Ganymede, Jupiter’s largest moon. Scientists with NASA have taken a new look at the data collected during that historic encounter, providing tantalising new details about this strange celestial object, its unique magnetic shield, and its unusually bright auroras.

Scientists Identify Protein That Could Let Birds See Magnetic Fields

To help them navigate long distances across the globe, birds are thought to have proteins in their eyes that could perhaps let them literally see the Earth’s magnetic field, a bit like a natural heads-up display. Two teams of scientists now think they’ve identified the light-sensitive protein key to this process, which relies on an innate attribute of electrons called “spin,” one of the most quantum mechanical properties there is.

Drama Over How Eels Navigate Highlights Problems in Science Publishing

You might see science as splashy headlines and a barrage of new results—but in the background are people with emotions and ambitions, politics, and a system that promotes publishing novel findings above all. A new paper on eel navigation highlights some of these systemic troubles. Read More >>

Dogs and Certain Primates May be Able to See Magnetic Fields

Some animals are capable of magnetoreception — an added sense that helps them detect magnetic fields. European scientists have now learned that the molecule responsible for this trait is also found in the eyes of dogs and some primates, which suggests they too might be capable of seeing magnetic fields.

The Earth’s Magnetic Field Could Flip Within a Single Lifetime

Earth's magnetic field is constantly shifting, and every 200,000 to 300,000 years or so it flips polarities completely. We're currently overdue for a switcheroo and scientists now say it could happen in as little as 100 years, potentially altering life in unexpected ways. Read More >>

Magnetic Field Art Will Make You Miss Your Old CRT Display

Remember how awesome it was to hold up a magnet to an old CRT display, and then watch it degauss in a colourful, rainbow seizure? Well you probably don't have any CRTs on hand anymore, but German artist Carsten Nicolai has an installation that makes use of those same magnetic deformations, and it's still fun to watch.
