Major steps forward in understanding neutrino properties

In the quest to prove that matter can be produced without antimatter, the GERDA experiment at the Gran Sasso Underground Laboratory in Italy is looking for signs of neutrinoless double beta decay. The experiment has the greatest ...

Measuring stellar oscillations with Kepler

The Kepler satellite is famous for its discovery of thousands of exoplanets by continuously and meticulously measuring the brightnesses of over half-a-million stars for the signatures of transiting exoplanets. Less well known ...

Researchers uncover ocean iron level mystery

The middle of the Earth's oceans are filled with vast systems of rotating currents known as subtropical gyres. These regions occupy 40% of the Earth's surface and have long been considered remarkably stable biological deserts, ...

Researchers find reliable climate change data in nearby corals

Tracking climate change through corals has historically meant studying coral in remote locations, away from civilization and the related environmental conditions that might affect the data. But research compiled by University ...

Why does El Niño decay faster than La Niña?

Warm and cold phases of El Niño-Southern Oscillation (ENSO) exhibit a significant asymmetry in their decay speed. Generally, El Niño tends to turn into a La Niña event in the following June-July after its mature phase; ...

Spinning towards robust microwave generation on the nano scale

Spin-torque oscillators (STOs) are nanoscale devices that generate microwaves using changes in magnetic field direction, but those produced by any individual device are too weak for practical applications. Physicists have ...

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.
