A chemical called 6PPD-quinone (6PPD-Q), which forms when shaved-off tire particles come into contact with ozone, might interfere with the inner workings of brain cells, leading to Alzheimer's disease. Zhang and Zhang's new paper in the journal Open Medicine, "6PPD‑Quinone Exposu

New research could help make future mRNA vaccines easier to store and distribute. The study, involving RMIT University, the Massachusetts Institute of Technology and Harvard Medical School, identified conditions that help protect the particles that carry mRNA in dry vaccine patch

Researchers at Weill Cornell Medicine and Birkbeck, University of London, have identified a site where a commonly used anesthetic binds to sodium ion channels, revealing a molecular mechanism that may explain how these drugs dampen communication between neurons. Ion channels are

Ultrafine particles (UFPs) –smaller than 100 nanometres and invisible to the naked eye—contribute substantially to illness and mortality worldwide. That is the finding of an international study led by researchers at the Max Planck Institute for Chemistry in Mainz and The Cyprus I

You've already inhaled thousands of microscopic particles today. Some will be dust, pollen or soot, and some will be plastic. Microplastics—tiny fragments shed from clothes, tires or packaging—have been found pretty much everywhere. They're in oceans, soils, wildlife, remote moun

A philosopher has put forward an argument for rethinking how particles are defined within the standard model of particle physics

A proposed technique to counter global warming by spraying sun-reflecting particles near the poles would cause commercial flights to pass through clouds of sulphuric acid, posing a danger to passengers and crew

When considering what makes up a human body, a physicist drills down beyond the atomic level. Columnist Chanda Prescod-Weinstein explores the not-exactly-real particles that allow the stuff we’re made of to hang together

Mysterious "little red dots" discovered in the early universe by the James Webb Space Telescope could harbor buried black holes that fire high-energy neutrinos through the cosmos.

For the first time, astronomers have directly mapped the magnetic field surrounding one of the Milky Way's most unusual pulsars, confirming a decades-old prediction about how particles stream away from the rapidly spinning stellar corpse.

Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outwar

Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?
