Using particles with various spins, theorists can probe space in more detail.

Timema females use particles of dirt, which they have previously ingested, to coat their eggs.

Using exotic particles and rays to probe hidden layers of the universe is an accomplishment that would make any physicist's short list.

These are real measurements, not using hypothetical particles.

Red was particularly difficult to produce, using particles of copper under delicately controlled redox conditions.

The experiment is normally conducted using electrically neutral particles or atoms.

This "time dilation" effect can actually be observed in the laboratory using subatomic particles.

One route to improve this resolution is to use particles with smaller λ, such as high-energy electrons.

It is not possible to communicate information faster than the speed of light using entangled particles.

Because the only evidence of entanglement comes from correlations that are analyzed after the fact, there is no way to communicate using entangled particles.
