In some hours, at midnight between Friday and Saturday, ten more countries will join the European Union. The EC-supported Venus Transit 2004 (VT-2004) programme is active in almost all of these, with VT-2004 National Nodes already established the Czech Republic, Hungary, Malta, Poland, Slovenia and Slovakia; more are likely to follow soon. The organisers include the Astronomical Institute of the Academy of Sciences of the Czech Republic and the next VT-2004 meeting will be held near Prague on May 7-9 (see below).
Venus Moves Closer
"Catching up" with the Earth in its orbit (see VT-2004 Animation C), Venus will be placed exactly between the Sun and our planet in the morning of June 8, the day of the extremely rare event, known as a "Venus Transit". Observers in the eastern hemisphere will be able to see Venus as a black spot slowly crossing the solar disk during about 5 1/2 hours.

Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
