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 dying star, a white dwarf identified as WDJ1524-0030, located in the constellation Ophiuchus in the southern sky, is losing its brightness as it cools, its…
Scientists have devised a new technique for real-time detection of freely moving individual neutral atoms that is more than 99.7% accurate and sensitive enough…
The researchers describe their work in a paper accepted for publication in the Journal of the American Chemical Society, and posted on the journal’s Web site.Scientists have long been puzzled by nature’s ability to use cheap and plentiful building blocks – iron, nickel and sulfur – to achieve the catalytic performance seen in rare and expensive metals. In particular, two enzymes – iron-iron hydrogenase and nickel-iron hydrogenase – function as hydrogen processors, much like platinum….
