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

A shift to cleaner transportation could prevent more than 3,600 premature deaths in Montreal and Toronto by reducing ultrafine particle pollution, a new study led by McGill researchers found.

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

On Episode 216 of This Week In Space, Rod Pyle and Tariq Malik talk with physicist Dr. Daniel Whiteson about other intelligences is beyond our scope.

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.
