Wildfire smoke is no longer just a short‑lived air quality problem drifting over cities for a few hazy days. New research shows that when these plumes rise high into the atmosphere, they can spawn ...

Scientists discovered microscopic gold forming inside tree needles. Hidden microbes convert dissolved soil ions into solid metal, offering a greener, innovative approach to exploring underground ...

Download the experiment instructions HERE! Let’s learn about the properties of liquids and solids: Solids are not compressible, they’re rigid, they don’t flow, and their particles are packed close ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete. For the first time, ...

Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size ...

Scientists are baffled by solid gold particles found in Norway spruce needles. Previously thought impossible, this discovery ...
