Spinning quasiparticles light up when paired with a light-emitting quasiparticle
The pairing between spinning quasiparticles called magnons and light-emitting quasiparticles called excitons will allow researchers to see spin directions, an important consideration for several quantum applications.

Reconstruction of the ecosystem in Bahariya Oasis 98 million years ago
Researchers have discovered a new kind of large-bodied, meat-eating dinosaur (as yet unnamed) from the abelisaurid group of theropods. The fossil was found in a middle Cretaceous-aged rock unit known as the Bahariya Formation, which is exposed in the Bahariya Oasis of the Western Desert of Egypt. ...This is an NSF Multimedia Gallery item.

Can we bring the materials we'll need in space, or will we be able to build when we get there?
The costs associated with sending materials into space are very high, as we return to the moon and look at interplanetary exploration, researchers are exploring in situ 3D printing construction possibilities using simulated Martian soil.This is an NSF Multimedia Gallery item.

Micro-ring resonator generates high-dimensional photon pairs
This micro-ring resonator, shown here as a closed loop, generated high-dimensional photon pairs. Researchers examined these photons by manipulating the phases of different frequencies, or colors, of light and mixing frequencies, as shown by the crisscrossed multicolor lines.

In microgravity there is no buoyancy to make bubbles dissipate. Could light make that process occur?
Researchers at University of California, Santa Barbara have sent an experiment to the International Space Station National Lab looking at the boiling process. On Earth, bubbles dissipate, but in microgravity there are no forces to make that happen. Could light waves make that process occur?This is an NSF Multimedia Gallery item.
