Experiments show that iron’s crystal lattice expands to incorporate helium. Read More »
A new model captures the flow of heat from ocean water into floating ice, providing an important input for efforts to predict future melting in the Arctic. Read More »
The energy required to fracture a lattice material obeys a scaling law governed by just three parameters, researchers find. Read More »
By measuring the melting temperature of iron under high transient pressure, researchers set a limit on the temperature at the boundary between the inner and outer cores. Read More »
A “Little Earth Experiment” inside a giant magnet sheds light on so-far-unexplained flow patterns in Earth’s interior. Read More »
Using a detailed simulation, researchers reveal how climate change will affect the regional dynamics of the conveyor-belt-like circulation of water through the Atlantic Ocean. Read More »
Experiments with small falling particles show that their orientations oscillate—which may help explain the settling of volcanic ash and the formation of snow. Read More »
The onset time for “viscous fingering”—an instability that can occur at a gas–liquid boundary—depends on the compressibility of the gas, offering a way to control the behavior. Read More »
Researchers revisit a neglected decay mode with implications for fundamental physics and for dating some of the oldest rocks on Earth and in the Solar System. Read More »
Laboratory experiments elucidate the directions and speeds at which acoustic waves propagate in the type of iron that likely makes up Earth’s core. Read More »
