Seeing double: NASA missions measure solar flare from 2 spots in space

more »
Solar flares are intense bursts of light from the sun. They are created when complicated magnetic fields suddenly and explosively rearrange themselves, converting magnetic energy into light through a process called magnetic reconnection -- at least, that's the theory, because the signatures of this process are hard to detect. But during a December 2013 solar flare, three solar observatories captured the most comprehensive observations of an electromagnetic phenomenon called a current sheet, strengthening the evidence that this understanding of solar flares is correct.

Exfoliating thinner flakes of phosphorene at higher yield

more »
By deoxygenating water, researchers discovered a new way to exfoliate phosphorene into atomically thin flakes. In order for phosphorene to reach its full potential, it needs to be incredibly thin -- preferably at the atomic scale. Until now, researchers have experienced difficulties in exfoliating atomically thin flakes from the bulk material, called black phosphorus, in a quick and efficient manner.
