High pressure in the deep ocean may squeeze nutrients from sinking “marine snow,” feeding deep-sea microbes and altering how ...

A recent study has uncovered compelling evidence suggesting that the climate effects of new particles in urban areas have been significantly underestimated. Particles play a crucial role in climate ...

In a twist on conventional wisdom, researchers have discovered that in ocean-like fluids with changing density, tiny porous particles can sink faster than larger ones, thanks to how they absorb salt.

Microplastics (MPs), defined as plastic fragments with sizes ranging from millimeters (<5 mm) to nanometers, have become a growing environmental and public health concern. First identified in the ...

ELECTRONIC SYSTEMS do not respond well to highly charged particles. Accelerated to near the speed of light by Earth’s magnetic field, such particles pack enough kinetic energy to cause damage. History ...

Researchers from the Okinawa Institute of Science and Technology (OIST) and the University of Oklahoma have pinpointed a one-dimensional system where such particles can exist and have examined their ...

China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...

Transmission electron micrograph of SARS-CoV-2 virus particles, isolated from a patient. Image captured and color-enhanced at the NIAID Integrated Research Facility (IRF) in Fort Detrick, Maryland.

Aerosols refer to fine solid or liquid particles suspended in the atmosphere, where they reside typically for days to weeks before falling to the ground or being washed out by rain or snow. They arise ...
