Single-particle infrared imaging reveals bottled-water nanoplastics differ in source, shape, and molecular structure beyond ...

New insights highlight the growing use of complementary techniques, including dynamic imaging, to assess subvisible particles ...

An analysis of counting-efficiency effects in non-volumetric particle counters explains discrepancies across channels.

Researchers from Brown University and their collaborators have developed a new way to measure the properties of cells—an important development, they say, because accurate measurements of changes in ...

Some innovations in physics come from entirely new technologies, others from fresh theoretical insights. Others still take shape by bringing together existing tools in new ways, working out how to ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most successful theories, hinting at unknown forces or quantum objects. Now, an ...

A new particle has popped into existence at CERN’s Large Hadron Collider, a heavier proton-like particle that contains two charm quarks. Protons and neutrons are examples of a class of particles ...

The United States Pharmacopeia (USP) and others, such as EP, JP, and ChP, have developed test techniques to ensure that particle counts are kept to a minimum in intravenous injections (parenteral ...

In July 2012, physicists at the Large Hadron Collider (LHC) in Europe triumphantly announced the discovery of the Higgs boson, the long-sought linchpin of the subatomic world. Interacting with Higgs ...

In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of chemical reactions to producing highly reliable weather forecasts. For now, ...

Every time two beams of particles collide inside an accelerator, the universe lets us in on a little secret. Sometimes it's a particle no one has ever seen. Other times, it's a fleeting glimpse of ...
