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…
To enable this, researchers of the German Center for Neurodegenerative Diseases (DZNE) have developed a computer-based procedure that identifies individual…
The Magnetometer will monitor magnetic field variations around the Earth and enable forecasters at NOAA's Space Weather Prediction Center to better predict the…
The inner Van Allen radiation belt is fairly stable, but the outer one changes shape, size and composition in ways that scientists don't yet perfectly…
Irradiation with heavy ions is suitable in particular for patients suffering from cancer with tumours which are difficult to access, for example in the brain.
Together with teams from Finland and Japan, physicists from the University of Basel were able to place 20 single atoms on a fully insulated surface at room…
Weizmann Institute scientists have demonstrated for the first time a photonic router – a quantum device based on a single atom that enables routing of single…
clamping system with integrated shoulder element for friction stir welding.
Unique nano-seals allow for forgery-proof object identification. Due to a combination of ion irradiation and simultaneous co-deposition of metal atoms a unique surface pattern is created. Its manufacturing process and its size of only a few square micrometers make it impossible to be reproduced, thus creating a forgery-proof identifier.
A method and components to fibre-couple multiple light sources in a highly efficient way is proposed. The new technique simplifies the process with which a side coupling arrangement for a double-cladded target fibre can be realized. In addition it improves the coupling efficiency compared to the so far existing state of the art.
Hybrid plasma-laser micro-structuring provides a tool for treating fused silica without the need for a time consuming preconditioning of the surface or the use of expensive vacuum-UV- respectively mid-wavelength-IR-lasers. The use of a hydrogenous plasma prior to the ablation process causes a temporary increase of the absorption in a more easily accessible wavelength region.
The invention describes a procedure to improve fluid mechanically the efficiency of chemical reactions and methods for emulsification and dispersion. This is done by generating hydrodynamically oscillating cavitations in a very efficient and homogenous way.
These monthly lunar scans are key to ensuring the land-imaging instrument aboard Landsat 8 is detecting light consistently. For this, engineers need a…
“One of the great challenges of modern astrophysics has been the quest to identify the first generation of stars to form in the universe, which we refer to as…
The Universe is filled with objects springing to life, evolving and dying explosive deaths. This new image from the NASA/ESA Hubble Space Telescope captures a…
In quantum mechanics, interactions between particles can give rise to entanglement, which is a strange type of connection that could never be described by a…
