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…
Terahertz (THz) waves lie in the electromagnetic spectrum between microwaves and infrared radiation. They are invisible to the human eye. Since they are low in…
Novel computational methods have helped create the most information-packed universe-scale simulation ever produced. The new tool provides fresh insights into…

In their experiments, the group fired a powerful laser pulse at a micrometer-sized plastic sphere, blasting a bunch of protons from the target and accelerating…
The data on so-called “magnetic reconnection” came from a quartet of new spacecraft that measure radiation and magnetic fields in high Earth orbit.
Conventional electronics rely on controlling electric charge. Recently, researchers have been exploring the potential for a new technology, called spintronics,…
Over the last half-century, many molecules have been discovered in space. Using radio telescopes, astronomers have with the help of these molecules been able…
With the advantages of small size, stability and high quality factors, nanomechanical resonators are considered as a promising candidate to storage, manipulate…
Man is a warm-blooded animal. If it gets too hot for him, he can tune down his body temperature. This feat is achieved by an evolutionarily refined “AC system”…
Within the emerging field of spin-based electronics, or spintronics, information is typically defined by the orientation of the magnetization of ferromagnets….
