a person is holding three different colored lights in one hand and pointing to the light on the other

This unique Science Snack is modeled after the Exploratorium exhibit, Colored Shadows! We can learn about human color perception by using colored lights to make additive color mixtures. For instructions on how to make this Science Snack, visit http://explo.me/TJ7R30ndYph

an image of some sort of structure in the air with words above it that read, all the atomic nucleus

Groups of quarks hold more complex information that encode another level of entities, such as protons and neutrons. The interaction of the three valence quarks within each nucleon creates an electromagnetic signature that repulses protons from one another. What holds them together is the force released from their constituent quarks (residual strong force or nuclear force), that are exchanging information by releasing smaller groups of quarks and bosons in the form of mesons and gluons. The…

several glassware are lined up in front of a microscope with blue light coming from it

Physicists at Riken, a Japanese scientific research institute, recently found a way to show how extremely small amounts of heat can be manipulated to control magnetic whirlpools, otherwise known as skyrmions. This could be a stepping stone to creating more energy-efficient forms of computing. Skyrmions, information carriers, develop when the magnetic flux of atoms moves into specific patterns inside a material. Under some conditions, they organize into what’s called a skyrmion lattice.
