The positively charged particle at the heart of the atom is an object of unspeakable complexity, one that changes its appearance depending on how it is probed.

A new atomic-scale experiment all but settles the origin of the strong form of superconductivity seen in cuprate crystals, confirming a 35-year-old theory.

Robots can surpass the limitations on how high and far animals can jump, but their success only underscores nature’s ingenuity in making the most of what’s available.

When the brain encodes memories as positive or negative, one molecule determines which way they will go.

The key to understanding the origin and fate of the universe may be a more complete understanding of the vacuum.

Partnerships between engineers and biologists have begun to reveal how birds evolved their superb maneuverability.

Structural studies of the robust material called sporopollenin reveal how it made plants hardy enough to reproduce on dry land.

Protein buildups like those seen around neurons in Alzheimer’s, Parkinson’s and other brain diseases occur in all aging cells, a new study suggests. Learning their significance may reveal new strategies for treating age-related diseases.
