After 20 years of trying, scientists have transformed mature cells into primordial blood cells that regenerate themselves and the components of blood. The work, described in Nature, offers hope to people with leukaemia and other blood disorders who need bone-marrow transplants but can’t find a compatible donor. If the findings translate into the clinic, these patients could receive lab-grown versions of their own healthy cells.

An active region that had just rotated into view blasted out a coronal mass ejection, which was immediately followed by a bright series of post-coronal loops seeking to reorganize that region's magnetic field (April 19, 2017).
The bright loops are actually charged particles spinning along the magnetic field lines. The action was captured in a combination of two wavelengths of extreme ultraviolet light over a period of about 20 hours. https://sdo.gsfc.nasa.gov/gallery/potw/item/798
