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…

In vivo like models are very important in the field of pharma- and medical research. They provide the ability to analyse complex rela-tions under defined…
Several alternative schemes are being explored to possibly overcome these limitations, including the use of the electrons’ spin in electronics. Now a research…
Such visualization techniques are needed for everything from making a map of planetary orbits based on nightly measurements of where they are in the sky to…
A new experiment conducted at the Joint Quantum Institute (JQI)* examines the relationship between quantum coherence, an important aspect of certain materials…
Mathematicians at UC Davis have come up with a new way to crinkle up the fabric of space-time — at least in theory.”We show that space-time cannot be locally…
Instead of materials we can touch and see, instead of motions we intuitively expect like a ball rolling down a hill, or a cup that sits still on a table, most…
Phase-change semiconductors have the ability to switch back and forth between amorphous (non-crystalline solid) and crystalline phases upon heating. As such,…
The exoplanet candidate called UCF 1.01, is close to its star, so close it goes around the star in 1.4 days. The planet's surface likely reaches temperatures…
But life on Earth is substantially different from, well, almost everywhere else. Beyond Earth's protective atmosphere and extending all the way through…
Now, researchers from the U.S. and South Korea have developed a warning system capable of forecasting the radiation from these violent solar storms nearly…
The mystery of the origin of matter seems to have been solved. At the middle of last week, CERN, the European Organization for Nuclear Research in Geneva,…
Fire in enclosed military environments such as ship holds, aircraft cockpits and ground vehicles is a major cause of material destruction and jeopardizes the…
Mobile devices allow workers, including government employees, to work in multiple locations and to improve their efficiency. But the same features that make…
The Home Technology system, which has been developed by the French-based company of the same name, acts as home-care support by monitoring and analysing the…
Pluto’s new-found moon, visible as a speck of light in Hubble images, is estimated to be irregular in shape and between 10 and 25 kilometres across. It is in a…
