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 technique involves etching patterns into the silicon carbide surfaces on which epitaxial graphene is grown. The patterns serve as templates directing the…
Analysis of the new Hubble data shows that the nucleus has a diameter of approximately 0.93 miles (1.5 kilometers), which is consistent with previous estimates.
William Matthaeus, professor of physics and astronomy at UD, is involved in NASA's Solar Probe Plus project, which is slated to launch by 2018. The unmanned…
Clues on the Martian surface, such as features resembling dry riverbeds and minerals that only form in the presence of liquid water, suggest that Mars once had…
Features on Mars resembling dry riverbeds, and the discovery of minerals that form in the presence of water, indicate that Mars once had a thicker atmosphere…
A research team led by Jeremy Smith, who directs ORNL's Center for Molecular Biophysics and holds a Governor's Chair at University of Tennessee, used molecular…
In particular, exons of many genes encode protein variants involved with important cellular processes. While the measured differences between the variants are…
The system has been designed by scientists from this Madrid university for Núcleo CC, a company which develops surveillance systems for the maritime and…
Surrounding the Sun is a roiling wind of electrons and protons that shows constant turbulence at every size scale: long streaming jets, smaller whirling…
Unlike other instruments being built for NASA’s Solar Probe Plus, the Solar Wind Electrons, Alphas and Protons (SWEAP) experiment won’t sit comfortably behind…
The work, carried out at the UK's synchrotron facility, Diamond Light Source, reveals the potential of a new manmade material to replace lead-based ceramics in…
The present invention consists of novel fluorescent dyes that primarily feature a large Stokes shift and long fluorescence lifetime. This is a nearly unique…
This invention is suitable for measuring the oxygen concentration in gas and liquids using optical fibre technology. Oxygen concentration measurement in…
The process permits an increased proportion of methane in biogas by introducing hydrogen into the biogas plant. The hydrogen is not pumped into the biogas…
The invention consists in a process and a device for the continuous liquefaction of biomass. An upward flow in the ambient liquid of the fermentor brings the…
Transitions between different phases of matter are a phenomenon occurring in everyday life. For example water – depending on its temperature – can take the…
