All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the ...

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven by dynamic processes deep within the planet’s core. Drawing on 11 years of ...

Researchers have created DNA-like magnetic nanostructures that form strong inter-helix magnetic bonds. These produce topological textures in the magnetic field, opening the door to the next generation ...

Over 40,000 years ago, Earth’s magnetic field underwent a full reversal, a rare phenomenon in which the North and South ...

The sun’s surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Our Sun is far from a smooth, white ball in the sky. Twisting and looping magnetic field lines rise from its surface like hair, causing dark, transient patches on the surface called sunspots wherever ...

Researchers at Aalto University have shown that a nanoparticle suspension can serve as a simple model for studying the formation of patterns and structures in more complicated non-equilibrium systems, ...

The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a magnet ...

Thanks to new calculations by a Dartmouth geochemist, scientists are now looking at the earth’s climate history in a new light. Mukul Sharma, Assistant Professor of Earth Sciences at Dartmouth, ...

(Nanowerk News) Scientists have used state-of-the-art 3D printing and microscopy to provide a new glimpse of what happens when taking magnets to three-dimensions on the nanoscale – 1000 times smaller ...

An electric field transforms an iron oxide nanoparticle suspension into a model for the emergence of complex dissipative structures. Researchers at Aalto University have shown that a nanoparticle ...
