Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
Yet, in space, similarly small fluctuations in the solar wind as it streams toward the Earth's magnetic shield actually can affect the speed and strength of…
Quantum theory is the study of physics at the atomic and sub atomic level. It quantises energy and momentum and shows how objects are characterised as both…

The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. As electronic devices get smaller, their…
The microscopic mechanism proposed by the researchers differs significantly from the usual half-metal model based on a strong electron-electron interaction….
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole…
Three years ago, the National Science Foundation provided a pair of University of Illinois professors with a grant to develop technology called…
Researchers have developed new software that makes it possible to use low-cost, thermal cameras attached to mobile phones to track how fast a person is…
Controlling the magnetic properties of materials is fundamental for developing memory, computing and communication devices at the nanoscale. As data storage…
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined…
A lower density likely means that at least part of Mars' crust is relatively porous. At this point, however, the team cannot rule out the possibility of a…
The study, published in Science Advances, builds on the initial discovery in 2009 of water and a related molecule — hydroxyl, which consists of one atom each…
For the first time, an international team led by engineers at Caltech has developed a computer chip with nanoscale optical quantum memory.
The coherent amplification of a localized optical signal within a planar titanium nitride nanoantenna has been achieved by scientists of Kazan Federal…
The new simulation captures the physics of magnetic reconnection, the breaking apart and snapping together of the magnetic field lines in plasma that occurs…
