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…
This trend has led some to conclude that the Sun has played a significant role in modern climate change. However, a discrepancy between two parallel series of…
The study, published Thursday in the journal Geology, examined an 18-square-mile chloride salt deposit (roughly the size of the city of Boulder) in the…

Skygazers at northern latitudes are familiar with the W-shaped star pattern of Cassiopeia the Queen. This circumpolar constellation is visible year-round near…
In FRET (Fluorescence Resonance Energy Transfer) experiments, dark quenchers like Dabcyl are widely used to avoid background noise resulting from an overlap between quencher and reporter fluorescence spectra. They provide a predictable way of modulating the fluorescence emission intensity of fluorophores without occupying an emission bandwidth. Although Dabcyl is one of the most frequently used fluorescence quencher, the very poor solubility in aqueous solutions due to its hydrophobic properties limits its use in biological systems where the natural solvent is water. The present invention provides a new dark quencher called Hydrodabcyl, which represents the hydrophilic alternative to Dabcyl.
