Atomic physicists “are jacks of all trades,” according to Alex Sushkov. “You have to have the idea, design the experiment, build the experiment, run the experiment, fix everything, take data, analyze ...

“Migratory birds possess a true magnetic compass—they can actively sense and extract directional information from the Earth’s ...

Many migratory birds use Earth’s magnetic field as a compass, but some can also use information from that field to determine more or less where they are on a mental map. Eurasian reed warblers ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

A team of researchers used tiny imperfections on a diamond lattice to successfully measure ...

From ancient compasses to modern smartphones, magnetometers have quietly shaped how we sense and navigate the world. Let us explore the fundamentals behind these field-detecting devices. Magnetic ...
