Salt Affects Particle Spreading

Microplastics are proliferating in our oceans (and everywhere else). This video takes a look at how salt and salinity gradients could affect the way plastics move. The researchers begin with a liquid bath sandwiched between a bed of magnets and electrodes. Using Lorentz forcing, they create an essentially 2D flow field that is ordered or chaotic, depending on the magnets’ configuration. Although it’s driven very differently, the flow field resembles the way the upper layer of the ocean moves and mixes.

The researchers then introduce colloids (particles that act as an analog for microplastics) and a bit of salt. Depending on the salinity gradient in the bath, the colloids can be attracted to one another or repelled. As the team shows, the resulting spread of colloids depends strongly on these salinity conditions, suggesting that microplastics, too, could see stronger dispersion or trapping depending on salinity changes.

Earth's Magnetic Field Booms Like a Drum, But No One Can Hear It

You may not be able to hear it, but Earth's magnetic shield booms like a drum when it's bombarded by strong impulses, including those from solar wind, a new study finds.

By Laura Geggel, July 06, 2022

"Every time an impulse strikes the shield's outer boundary — a region known as the magnetopause — jolts ripple through its surface and then are reflected back once they reach the magnetic poles, just like the face of a drum ripples as a percussionist beats it.

"Movements in the magnetopause can impact the flow of energy within Earth's space environment, Archer noted. For instance, the magnetopause can be impacted by solar wind, as well as charged particles in the form of plasma that blow off the sun. These interactions with the magnetopause, in turn, have the potential to damage technology, including power grids and GPS devices."
