The discovery, by an international team of scientists led by University College London (UCL), the Open University (OU), and the Free University of Berlin, of a frozen sea close to the equator of Mars has brought the possibility of finding life on Mars one step closer. This is the first evidence of there having been recent liquid water on Mars. Higher levels of methane over the same area mean that primitive micro-organisms might survive on Mars today. The 3D images of pack ice near the Martian equator have been taken by the High Resolution Stereo Camera on board the Mars Express probe.
The results of the work by the team lead by John Murray (OU), Jan-Peter Muller (UCL), and Gerhard Neukum (Free University of Berlin) were presented at an ESA Mars Science Conference at ESTEC, Netherlands on 21 February 2005, and are to be published in the scientific journal Nature next month.
Professor Muller, Department of Geomatic Engineering, UCL, one of two UK co-investigators on the project, said: “This is a historic moment for Mars exploration when a previously neglected region reveals its secrets. Speculations that this area might have water close to the surface have been shown to be correct. This is one of many discoveries that we expect the European Space Agency to make with Mars Express and the Aurora programme, given future UK support.”

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...
