Human-made microbeads don’t always go with the flow. Under certain conditions, the artificial particles can align themselves with a fluid’s flow and then swim upstream, researchers report May 1 in ...

But such measurements are notoriously challenging: the instruments used are themselves governed by quantum laws, and their interaction with particles can alter the very properties they are meant to ...

For decades, scientists have debated the impact of human-made and environmental particles in the atmosphere, called aerosols, on severe weather. Climate studies suggest aerosols may help shape and ...

Aircraft particles became more reactive during simulated aging, while ship emissions followed a different pattern in the same ...

Prof Francis Halzen won for "decisive contribution" to developing the IceCube Neutrino Observatory Belgian-born physicist Prof Francis Halzen has won the Nobel Prize in Physics for his pioneering work ...

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 ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

The concept of particles traveling faster than light, named tachyons, though largely theoretical and unobserved, holds an intriguing place in recent cosmological models. According to a study not yet ...

Small particles from tires inhibited the growth and caused adverse behavioral changes in organisms found in freshwater and coastal estuary ecosystems, two new research papers found. Small particles ...
