Understanding long-term trends in ocean layering

Water layering is intensifying significantly in about 40 percent of the world's oceans, which could have an impact on the marine food chain. The finding, published in the Journal of Geophysical Research: Oceans, could be ...

The interiors of stars

The interiors of stars are largely mysterious regions because they are so difficult to observe directly. Our lack of understanding about the physical processes there, like rotation and the mixing of hot gas, introduces considerable ...

Atlantic and Pacific oscillations lost in the noise

The Atlantic Multidecadal Oscillation (AMO) and the Pacific Decadal Oscillation (PDO) do not appear to exist, according to a team of meteorologists who believe this has implications for both the validity of previous studies ...

Seasonal forecasts challenged by Pacific Ocean warming

CSIRO research has found global warming will make it more difficult to predict multi-year global climate variations, a consequence of changes to long-term climate variability patterns in the Pacific Ocean.

Researchers reveal a wide band gap topological insulator

Since their discovery in 2006, topological insulators have been widely discussed as a promising avenue for energy efficient electronics. Their unique high-mobility edge states have a form of "quantum armor" that protects ...

Oscillation

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes is used to be synonymous with "oscillation". Oscillations occur not only in physical systems but also in biological systems and in human society.
