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 technology has the potential to substantially reduce production costs and also promises better image resolution than is possible with today's detectors….
Transistors are made out of diodes, which rectify electrical currents: however hard one pushes electrons in both directions, they flow only in one. Now an…

The technology, called acoustic-assisted magnetic recording, has been presented at a professional conference, and a patent application was filed this week.Magnetic storage of data is one of the most inexpensive and widespread technologies known, found in everything from computer hard drives to the magnetic strip on a credit card. It’s permanent, dependable and cheap. However, long-term reliability of stored data becomes an increasing concern as the need grows to pack more and more information in storage devices, experts say….
Such remnants have long been thought to be the source of cosmic ray particles hitting Earth. The observations show, for the first time, the presence of “seed…
The team led by Rainer Blatt reversed a quantum measurement in a prototype quantum information processor. The experiment is enabled by a technique that has…
“Scientists have been trying to find the sources of high-energy cosmic rays since their discovery a century ago,” said Elizabeth Hays, a member of the research…
