Aerosols vary in composition, size, concentration, and source. They profoundly affect climate, visibility, human health, and biogeochemical cycling. Particle sizes are determined by the mechanism ...

A halo of gamma-rays detected by the Fermi Space Telescope matches what would be expected if particles with masses around 500 ...

A new study suggests that many theorized heavy particles, if they exist at all, do not have the properties needed to explain the predominance of matter over antimatter in the universe. If confirmed, ...

The ability of atmospheric aerosol particles to seed the formation of the droplets that collect into climate-influencing clouds depends primarily on the particles' size, not their chemical ...

Scientists working with the James Webb Space Telescope discovered three unusual astronomical objects in early 2025, which may ...

Dark matter, the mysterious substance that exerts gravitational pull but emits no light, might really consist of vast concentrations of ancient black holes created at the very start of the universe, ...

“At first, we thought it was absurd,” Asimina Arvanitaki tells me when we meet in her office at the Perimeter Institute for Theoretical Physics in Waterloo, Canada. I’m not surprised. How else could ...

Poor air quality may increase the risk of in-hospital death among patients with ischemic stroke by up to 24%, depending on the size of air pollution particles, new research shows. Investigators found ...

In this Universe, there are very few fundamental properties that cannot be derived from something simpler. The rules governing biological systems are rooted in chemical interactions, bonds, and ...
