When water freezes into ice or boils into vapor, its properties change dramatically at specific temperatures. These so-called phase transitions are fundamental to understanding materials. But how do ...

Every 11 years or so, the Sun’s magnetic field completely flips, meaning its north and south poles switch places. This periodic change is known as the solar cycle. Story continues below this ad The ...

Purpose: Magnetic particle imaging (MPI) is a nascent tracer imaging modality that generates images from magnetic iron oxide nanoparticles (MIONs) in tissue. MPI resolution is a critical input ...

Abstract: This paper presents a novel method of magnetic flux leakage testing to estimate the circumferential positions of multiple cracks in a cylindrical ferromagnetic rod by measuring the ...

Between 15 million and 6 million years ago, deepening of Earth’s ocean basins may have caused a sea level change of similar ... in hydrothermal flux near oceanic ridges. They suggest this ...

The UN Environment Programme (UNEP) called on Tuesday for urgent action to combat climate change, biodiversity loss, and pollution, warning that progress on all fronts remains slow and uneven.

One of the many unseen forces to which you owe your existence is magnetism. If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely ...
