When the sun is straight up at noon, you see blue sky because all the other colors in the spectrum up until blue and purple are scattered away. This is known as the Rayleigh effect. We usually don't ...

Scientists have observed a unique particle that moves easily one way, yet resists at 90 degrees. These semi-Dirac fermions were observed using their energy signature in a topological metal. Particles ...

If you've ever watched a flock of birds move in perfect unison or seen ripples travel across a pond, you've witnessed nature's remarkable ability to coordinate motion. Recently, a team of scientists ...

A research team has discovered that achiral hard banana-shaped particles can spontaneously form exotic structures like skyrmions and blue phase III phases. Skyrmions are tiny vortex-like structures ...

Succulents glow in shades of red, green, blue, and more after being infused with afterglow phosphor particles that absorb and slowly release light. CREDIT: Liu et al., Matter 2025 Get the Popular ...

Researchers suggest that dark matter might subtly color light red or blue as it passes through, revealing traces of its ...

Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move ...
