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…
Finding life on Mars could get easier with a creative adaption to a common analytical tool that can be installed directly on the robotic arm of a space rover.In a recent paper published online in the journal Planetary and Space Science, a team of researchers propose adding a laser and an ion funnel to a widely used scientific instrument, the mass spectrometer, to analyze the surfaces of rocks and other samples directly on Mars' surface. The researchers demonstrated that the combined system could work on the spot, without the sample handling that mass spectrometry usually requires….
According to the German Association for Information Technology, Telecommunications and New Media (BITKOM), 34.4 billion SMS have been sent in Germany in 2009. This means that each German has typed an average of 420 short text messages into their mobile. The potential consequences of sending SMS messages on a regular basis has been examined by Dr. Sascha Topolinski, psychologist in Würzburg – but from a surprising angle. The results of his work have now been published by Psychological Science….
