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…

Professor Ritter and his co-workers from the Division of Virology, University Hospital of the RWTH Aachen, created a new recombinant Epstein-Barr Virus (EBV)
which has lost the ability to enter the state of latent persistency after infecting host cells. The mutant virus only causes a self-limited infection and is unable to immortalize B-lymphocytes following Infection. Having lost the oncogenic potential of wild type EBV it fulfils the prerequisite for a live vaccine.
The inventors generated a mutant virus allowing expression of lytic genes, but preventing the expression of EBV encoded genes essential for the establishment of
viral latency. Mutant virus infected B-lymphocytes died after the productive phase….
