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…
Frontal Polymerization initiated by a stimulus of light/ heat at the surface is a technique in which the polymerization heat is used for the cleavage of a thermal initiator which can reinitiate the polymerization reaction in adjacent regions. This effect leads to a moving localized reaction zone which is referred as reaction front.
The personal information of millions of smartphone users is at risk due to in-app advertising that can leak potentially sensitive user information between ad…

Handedness is a peculiar breaking of symmetry where a mirror image of a structure or pattern is different from its original. While the most well-known example…
A simple, feasible method for the production of laminate composites, consisting of a perforated substrate and a polymer membrane, now allows for the production of tactile displays the size of a computer screen. The procedure developed at Furtwangen University now enables the coating of large substrates with a high-quality membrane film, without creating air bubbles at the bond interface. The new method is environmentally-friendly, as the carrier is reusable and no chemicals are required to reduce adhesion. The procedure can be integrated into commercially available lamination systems.
Ultrasound is an acoustic wave at a frequency well above the human audible limit. Ultrasound in the megahertz range (1 MHz = 106 Hz = 1 million oscillations…
While a classical bit found in conventional electronics exists only in binary 1 or 0 states, the more resourceful quantum bit, or 'qubit' is represented by a…
Topological insulators are therefore highly conductive at their surfaces and electrically insulating within. Only magnetic fields should destroy this mobility,…
POLARIS is the world's most powerful fully diode-pumped laser system and with it, the University of Jena possesses a petawatt-class laser, which produces the…
Using NASA's Hubble Space Telescope, astronomers at the University of Arizona have taken the first direct, time-resolved images of an exoplanet. Their results…
“The result is very exciting,” said Daniel Apai of the University of Arizona in Tucson, leader of the Hubble investigation. “It gives us a unique technique to…
Forschungszentrum Jülich has begun to develop a concept for cost-efficient neutron sources which could replace mid-sized facilities. The new sources will…
