Pushing the limits of how we see and manage magnetic behavior in tiny structures is key to developing future technologies, ...

"Magnetar birth rates and formation scenarios are among the most pressing questions in high-energy astrophysics." ...

In 1862, James Clerk Maxwell published his famous Maxwell’s equations. This was at a time when humans were just starting to ...

How it works Artist’s impression of how an ultrafast disruption of superconductivity in a YBCO thin film triggers an abrupt ...

A mysterious menagerie of quantum states — once purely theoretical — has been brought to life by researchers at Columbia ...

Stars are the architects of nearly all the chemical elements in the universe, including ones crucial to life as we know it, such as carbon and oxygen. Yet, despite decades of research, aspects of star ...

That’s the subtle magnetic force—generated by the planet’s molten metal core—that surrounds Earth, not unlike the force around a bar magnet. The intensity and direction of the field vary across ...

This period, called the Laschamps excursion, lasted around 2,000 years. The strength of Earth’s magnetic field dropped to just 10% of its current level, while the magnetic poles wandered far ...
