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 object, aptly named the Necklace Nebula, is a recently discovered planetary nebula, the glowing remains of an ordinary, Sun-like star. The nebula consists…

One of the earliest lessons in science that students learn is that a ray or beam of light travels in a straight line. Students also learn that light rays fan…

Hydrogen sulphide is a highly toxic and corrosive environmental pollutant with an obnoxious smell, the removal of which is necessary for pollution control and processing requirements within industry.
The invention demonstrates that specially modified iron, manganese, cobalt and nickel porphyrins can be used for the efficient catalytic removal of hydrogen sulphide species (H2S, HS-, S2-), here labelled “H2S”.
Otherwise, the light beams would interfere with lasers and other photonic components on the chip and make the chip unstable. The breakthrough marks a…
