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…
Now, armed with more sophisticated data from a satellite mission observing the cosmic microwave background – a faint glow in the universe that acts as sort of…
On the one side, there are tiny fragments of diamond. Besides carbon diamond contains other atoms as natural impurities. These impurity atoms or so-called…
Gordon, the unique supercomputer launched last year by the San Diego Supercomputer Center (SDSC) at the University of California, San Diego, recently completed…
A standard camera takes flat, 2-D pictures. To get 3-D information, such as the distance to a far-away object, scientists can bounce a laser beam off the…
Modern astronomers are also interested in studying the SMC (and its cousin, the Large Magellanic Cloud), but for very different reasons. Because the SMC is so…
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have discovered starburst galaxies earlier in the Universe's history than…
However, concentrations of volcanic activity are significantly displaced from where they are expected to be based on models that predict how the moon's…
SN Wilson belongs to a special class called Type Ia supernovae. These bright beacons are prized by astronomers because they provide a consistent level of…
The result is the most precise measurement to date of the ratio of positrons to electrons in cosmic rays. Measurements of this key ratio may eventually provide…
Reionization occurred a few hundred million years after the Big Bang as the first stars were turning on and forming the first galaxies. During this period, the…
Histone deacetylase inhibitors (HDACi) are promising anticancer agents and are currently being evaluated in clinical trials. However, due to their unselective…
Our own Milky Way, astronomers believe, is a spiral. Our solar system and Earth reside somewhere near one of its filamentous, swept-back arms. And nearly 70…
But despite their common shape, how galaxies like ours get and maintain their characteristic arms has proved to be an enduring puzzle in astrophysics. How do…
Numerous studies have shown that selective inhibition of the MetAP-II subtype halts the growth of endothelial cells in culture, inhibits angiogenesis in animal…
Siemens Industry Automation Division has extensively revised its network management software Sinema Server. The new version 12 allows each Sinema Server…
The proliferation of sensor-studded cellphones could lead to a wealth of data with socially useful applications — in urban planning, epidemiology, operations…
