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…
Reconfigurable antennas are very attractive for modern wireless communications because they allow the use of a single antenna for multiple systems. The…

Holography makes use of the peculiar properties of laser light to record and later recreate three-dimensional images, adding depth to conventionally flat…
A beam of sunlight is a mixture of different-colored light, including all the colors of the rainbow. Filtering or blocking a specific color, or colors, is…
Since 2011, eleven research teams from six European countries have been looking into the fastest and most effective ways of warning the public in the event of…
Technology’s workhorse for determining protein structures is X-ray protein crystallography, in which a beam of x-rays sent through a crystallized protein is…
Geometrical phases occur in many places in nature. One of the simplest examples is the Foucault pendulum: a tall pendulum free to swing in any vertical plane.Due to the earth rotation, the actual plane of swing rotates relative to the earth. One observes that every day the plane of rotation changes by a small “geometric” angle, associated to the spherical shape of the earth. …
Researchers are now thinking it was the former, as evidence of yet another black hole has been found in a globular cluster by an MSU-led team of researchers.As…
