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…

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and the third most common cause of cancer related death worldwide. Cure of HCC is only possible by complete resection in early stages, but only 10–20% of tumors can be curatively resected and the risk of HCC recurrence is high. In addition, HCC is resistant to conventional radio- or chemotherapy. As a result, the prognosis of HCC remains poor and new therapies are urgently needed. The discovery of so far unknown immunodominant epitopes of the tumor-associated antigen Glypican-3 and the according HLA-A2 restricted T-cell-receptor enable the development of an adoptive T cell therapy for HCC patients. Adoptive T cell therapies showed very promising results in cancer therapy over the last years. The Science Magazine even awarded this technology as “Breakthrough of the year 2013”. Therefore, the current invention provides the tools for a promising new approach for the therapy of HCC.

The novel pH value sensor works according to an optical electrochemical principle and comprises a photoluminescent or fluorescent layer, a light source and a detector. The layer comprises an electric potential and acts as a working electrode which is implemented as a nanostructure (nanowires with quantum dots). Furthermore, spatial resolution can be achieved by using numerous nanowires contacted individually on a carrier and a visual array detector (analogous to CCD sensors in digital cameras).
Other reactions or concentrations of substances can also be detected.
