This isn't exactly news, but interesting. In Nuclear Medicine, radioisotopes are used for imaging of the body by internal injection of the isotope (tomography). Positron Emission Tomography (PET) isotopes are unusual, and previously required a nearby expensive 'benchtop' cyclotron to produce, and personnel to run the cyclotron. This newer positron-emitting radioisotope is the decay daughter of a longer-lived radioactive parent, and can be extracted from the generator about every 4 hours due to the short half-life of the daughter. The generator lasts for a year or longer, and simply sits on a small area of the nuclear medicine hot-lab.
