Issues

The liquids’ opacity makes it impossible to look at their flow structure. Instead, researchers listen to it.

Strontium ruthenate may exhibit an exotic superconducting state composed of electron pairs with nonzero momentum.

Ice-dynamics models must be updated now that researchers have observed a thick layer of salty water in sediments beneath the West Antarctic Ice Sheet.

Technological immaturity, falling oil prices, overoptimistic investors, and regulatory uncertainty are blamed for the failure of a promising biofuel technology to perform as hoped.

Scientists in those and other countries want science to be separated from politics.

To understand Earth’s climate, think of it as a giant, planetary-scale heat engine that drives the circulation of the oceans and atmosphere.

The Nobel Prize winner was one of the founders of biophysics. He also helped rescue thousands of academics from Nazi-dominated Europe and contributed significantly to UK defense efforts in World War II.

In a former gold mine in South Dakota, an international particle-physics experiment will delve into the unexplained matter–antimatter imbalance that gave rise to the universe.

Attempts to solve the problem have led to a number of well-defined competing theories. Choosing between them might be crucial for progress in fundamental physics.
