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, new research and monitoring systems are clarifying what happens to disruptive clouds of electrons and other electrically charged particles, known as ions,…
Colloids require a delicate balance of opposing forces for them to be stable: attractive forces must be matched by repulsive ones. A new colloidal…
Engineers and scientists on the Phoenix team assembled at the University of Arizona are determining the best approach to get some of that material into the…
How do grains flow out of an emptying silo? And what about sugar poured out by a pastry chef? Like liquids (2), grains can flow, but there is no attraction…
To see the latest science of type-I superconductors, look no further than the froth on a morning cup of cappuccino. A team of U.S. Department of Energy's Ames…
The invention concerns a simple process for the large-scale production of high-porosity zinc silicate microcrystals using ionized liquids.

The method automatically detects within minutes when an Internet worm has infected a computer network. Network administrators can then isolate infected…
When you think of the solar system you probably picture a textbook diagram: nine planets, different sizes and colours, all circling the bright yellow sun. But…
The instrument, called the Kilodegree Extremely Little Telescope (KELT), has been assembled and is being tested at Vanderbilt¹s Dyer Observatory. Shortly, it…
Ultracold quantum gases made of strongly correlated particles are important models for the understanding of solid-state systems. Strong correlations between…
In a groundbreaking paper published as a cover story in this week’s Nature magazine, Northeastern University physicist Professor Albert-László Barabási and his…
A Johns Hopkins astronomer is a member of a team briefing fellow scientists about plans to use new technology to take advantage of recent, promising ideas on…
This majestic photographic display, which is planned for 7-29 June 2008, takes viewers on a colourful visual journey through the wonders of the Universe and…
As these results were obtained under ambient conditions they make diamond an ideal candidate for building a quantum computer working at room temperature. This…
Magnetic sensors are made of thin layers with different magnetic properties. With the help of ion technology, scientists from Dresden were now able to shrink…
“We could make huge telescopes on the moon relatively easily, and avoid the large expense of transporting a large mirror from Earth,” says Peter Chen of NASA…
