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…
The novel process permits the production of new, high-quality polyurethanes from polyurethane waste. The critical step of depolymerization is achieved by…
The invention presented here enables every user of a multimedia mobile communication device (mobile phone, for example) to act as a TV reporter. For example,…
Up to now, explosives based on nitroaromatic compounds have been detected as anions by means of ion-mobility spectroscopy (IMS). The present invention not only…
Now astrophysicists from the University of Zurich present the world’s first realistic simulation of the formation of our home galaxy together with astronomers…
“Incredibly, this source is still producing X-rays and may remain bright enough for Swift to observe into next year,” said David Burrows, professor of…
The positron emitting radionuclide 68Ga (T½ = 68 min) shows great potential for clinical Positron Emission Tomography (PET). The present procedure purifies…
In a hitherto unknown, wet-chemical redox reaction, which can be very easily and rapidly accomplished, largely spherical HgSe or HgTe particle clusters having…
Microstructural changes in small airways are characteristic for lung disease such as chronic obstructive lung disease (COPD). Spirometry is the common…
This advance provides a better picture of how polymer molecules respond under fast-flow, high-stress processing conditions for plastics and other polymeric…
Researchers at the National High Magnetic Field Laboratory's Pulsed Field Facility at Los Alamos National Laboratory have set a new world record for the…
Laser plasma accelerators offer the potential to create powerful electron beams within a fraction of the space required by conventional accelerators – and at a…
The new findings also suggest that the red-tinged dwarf planet may be covered in a thin layer of methane, the remnants of an atmosphere that's slowly being…
If fiber optic cable is ideal for carrying information, why haven’t photons replaced electrons entirely? Largely because miniaturizing photonic equipment all…
Cosmic distances are difficult to grasp and no less difficult to measure. When it comes to other galaxies or even remote parts of our own Milky Way, distance…
To probe the evolution of atomic nuclei with different shape —a factor which affects atomic stability—a large team of international researchers has added…
This project begins three years after beads of liquid brine were first photographed on one of the Mars Phoenix lander's legs. “On Earth, everywhere there's…
