New evidence for a human magnetic sense that lets your brain detect the Earth’s magnetic field

Your brain's sensory talents go way beyond those traditional five senses. A team of geoscientists and neurobiologists explored how the human brain monitors and responds to magnetic fields.
The orientations of the stone walls that crisscross the Northeastern U.S. can tell a geomagnetic tale as well as a historical one. John Delano

Old stone walls record the changing location of magnetic north

Scientific inspiration struck a geologist after many walks through the woods in New York and New England. These ruins hold the secret of where the compass pointed north when they were built centuries ago.
ESA’s Swarm constellation reveals new rapid changes of our magnetic field, tied directly to the heart of our planet’s molten iron core. ESA/ATG Medialab

Earth’s magnetic heartbeat, a thinner past and new alien worlds

Space research never stops and it seems neither do the surprises. On ABC Breakfast News I covered some huge results from the last few weeks. Be still my beating (magnetic) heart Earth’s magnetic field…

What the ‘weather’ is like on a star can help in the search for life

In the search for life on other planets in the universe we need to find the right kind of star, and it needs to have the right kind of space weather.

I’m stuck like glue: why I love magnets and you should too

I have a confession: I’m obsessed with magnets. We rely on magnets every day, but seldom give them a second thought. There are magnets in your credit card, your cellphone, your car, microwave oven and…

Magnetic fields can control heat and sound

Sound waves are made of particles called phonons. New research shows they're affected by magnetic fields, with researchers able to steer heat magnetically.
Magnetic traces suggest iron crystals in the innermost core are aligned east-west, rather than north-south. Lachina Publishing Services

Our view of Earth’s inner core is flipped on its side

The planet Earth’s inner core is not a single solid mass but comprised of two layers, and new evidence about the core’s composition from a team of US and Chinese geophysicists suggests that the innermost…
