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…
The discovery could give a new insight into just how energy is dissipated in solar system sized plasmas such as the solar wind and could provide significant…

An elderly lady is about to go to bed. She goes into her room, sits down on the bed, takes off her slippers and turns off the light. Suddenly, before getting…
Many classical algorithms in computer science include so called “random walks”, where possible ways to solve a problem are chosen at random. Algorithms of that…

Fish and some amphibians possess a unique sensory capability in the so-called lateral-line system. It allows them, in effect, to “touch” objects in their…
“The disks contain small comet- or asteroid-like bodies that may grow to form planets,” Debes said. “These small bodies often collide, which produces a lot of…
