    The tip of a scanning tunnelling microscope (STM) above chlorine atoms that have been deliberately moved. By moving individual atoms under their microscope, scientists were able to arrange vacancies in a single layer of chlorine atoms and create atomic lattices with a predetermined electrical response.

    Possibility to arrange the atoms precisely bring designer quantum materials closer to reality. Aalto University researchers have manufactured artificial materials with engineered electronic properties. By moving individual atoms under their microscope, they were able to create atomic lattices with a predetermined electrical response. The possibility to precisely arrange the atoms on a sample bring ‘designer quantum materials’ one step closer to reality...

    The grains that cover Saturn’s moon act like clingy packing peanuts. Experiments led by researchers at the Georgia Institute of Technology suggest the particles that cover the surface of Saturn’s largest moon, Titan, are “electrically charged.” When the wind blows hard enough (~15 mph), Titan’s non-silicate granules get kicked up and start to hop in a motion referred to as saltation...

    Planetary Waves, first found on Earth, are discovered on Sun

    Coronal BP detection at three distinct vantage points in space. BP detections by the STEREO and SDO spacecraft taken around 00:00 UT on 2 February 2011 when the entire solar corona could first be seen by all three spacecraft. The top row (a–c) shows coronal images from a plasma formed around 1.5 MK. The small bright concentrations seen in these images are BPs. The bottom row (d–f) shows the same images with respective BP detections15 shown in red (STEREO-Behind), white (SDO) and blue (STEREO-Ahead).

    Scientists partially re-insulated ravaged nerves in mouse models of multiple sclerosis (MS) and restored limb mobility by treating the animals with a small non-coding RNA called a microRNA...
