The orange carotenoid protein of cyanobacteria binds a single carotenoid pigment molecule that may dissipate excess light energy when it moves within the protein.

Changing Colors for Built-in Sunblock

Molecular movements triggered by light redirect the flow of energy through photosynthetic cells to protect them from sun damage.

Selective etching of palladium (blue) from palladium-platinum core-shell nanoparticles (left) yields hollow platinum (grey) nanocages with high activity for the oxygen reduction reaction.

Hollow and Filled with Potential

Hollow shape-selected platinum nanocages represent a new class of highly active catalysts.

MD simulation shows membranes with an asymmetric molecular distribution of about 0.6 nm; yellow = gold; red = organo-thiol ligand molecules.

Janus-like Nanoparticle Membranes

Sub-nanometer molecular asymmetry between the two different faces of nanoparticle membranes formed at air-water interface is revealed.

What Is the Size of the Atomic Nucleus?

The “neutron skin” of the nucleus of a calcium-48 atom is much thinner than thought. An international team of nuclear physicists led by Dr. Gaute Hagen of the Department of Energy's Oak Ridge National Laboratory used the Titan supercomputer to compute the neutron distribution and related observables of the atomic nucleus of calcium-48.
