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…
Inland waters are of outstanding importance in Germany and worldwide for drinking water supply, ecology, tourism and agriculture. In Saxony alone there are 23…
Contrary to previous assumptions, the new results show that the process known as the ‘proximity effect’ varies considerably at a nanometre scale. The results…
'Entanglement' describes a very particular type of quantum state which is not attributed to a single particle alone, but which is shared between two different…
