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…
NASA technologist Jonathan Pellish isn’t convinced. In fact, he believes a computing technology of yesteryear could potentially revolutionize everything from…
The machine is considered multiphase because it can study shock wave propagation through a mixture of gas and solid particles. Shock tubes — machines that…
The invention is a method for the manufacture of high surface area, pure polytype β-silicon carbide derived from renewable sources in a one-step-process. The…
Tokyo Tech es Toshihiro Osaragi and colleagues report on models for evacuation procedures in big cities after massive earthquakes based on the behavior of…
They stressed that it is the triple contact line and not the contact area of the droplet/solid interface that determines the macroscopic contact angle. The…
“Finding a second Pac-Man in the Saturn system tells us that the processes creating these Pac-Men are more widespread than previously thought,” said Carly…
Water repelling molecules are said to be hydrophobic. The hydration – or formation of water interfaces around hydrophobic molecules – is important for many…
In a previous Herschel study, scientists found that the dusty belt surrounding nearby star Fomalhaut must be maintained by collisions between comets. In the…
Metallic glass alloys (or liquid metals) are three times stronger than the best industrial steel, but can be molded into complex shapes with the same ease as…
Among the most important techniques developed in atomic physics over the past few years are methods that enable the storage and cooling of atoms and ions at…

In this new filter, which has been developed in a German university, the nanoparticles are evenly deposited. This is possible by using a finer basic material,…
According to this innovation SiO2-enriched additives are given to the binder containing compound. The carbon is then being oxidised inside of the sample, no…
In this process the clearance between the layers is being stabilised by a net of fine bridges, the pores of foamed ceramics. The layers can now be very thin…
This novel modelling processing now allows an efficient description and drive of parallel-kinematic machines by means of a universal procedure, and forms the…
