June 8th is World Oceans Day - a day to celebrate the oceans that connect and sustain all of us. Our colleagues at the Biodiversity Heritage Library have been leading up to today with a series of blog posts exploring historic publications that mark important milestones in the progress of marine bioscience research and ocean exploration.

The Contemporary Guerilla Gallery Berlin is a project by a group of Berlin-based artists. The experimental project explores new ways of dealing with the contemporary art market. Part of the concept of CGG Berlin is independent art selling on eBay, another part is making pop-up exhibitions without external curatorial influence.
At art space tetra we show video works of five of the CGG artists. The video works have a documentary character and thematize the process of art production.
At the opening Hannah Reber and Gert-Jan Akerboom will be present and give a brief introduction of the project and answer questions after the screening.
The CGG Berlin pop-up at art space tetra shows works by:
Hannah Reber (www.hannahreber.de)
Gert-Jan Akerboom (www.gertjanakerboom.com)
Ortrun Stanzel (www.ortrunstanzel.de)
Ties Ten Bosch (www.tiestenbosch.com)

Im Rahmen des TV Pop-Ups haben Gert-Jan Akerboom und Hannah Reber eine multimediale Installation gebaut. Der Bauplan wird von Gert-Jan Akerboom als Kunstwerk im Rahmen der CGG Berlin aus- und zur Verfügung gestellt. Viel Spaß beim Bauen! :*

Radio waves, microwaves and even light itself are all made of electric and magnetic fields. The classical theory of electromagnetism was completed in the 1860s by James Clerk Maxwell. At the time, Maxwell’s theory was revolutionary, and provided a unified framework to understand electricity, magnetism and optics.
Now, new research led by LSU Department of Physics and Astronomy Assistant Professor Ivan Agullo, with colleagues from the Universidad de Valencia, Spain, advances knowledge of this theory. Their recent discoveries have been published in Physical Review Letters.
Maxwell’s theory displays a remarkable feature: it remains unaltered under the interchange of the electric and magnetic fields, when charges and currents are not present. This symmetry is called the electric-magnetic duality.
However, while electric charges exist, magnetic charges have never been observed in nature. If magnetic charges do not exist, the symmetry also cannot exist. This mystery has motivated physicists to search for magnetic charges, or magnetic monopoles. However, no one has been successful. Agullo and his colleagues may have discovered why.
