An outbreak of lymphogranuloma venereum has been detected following reports of the disease in Europe. “From October 2004 to the end of April 2007, 492 cases of lymphogranuloma venereum were diagnosed in the UK. These cases were predominantly in men who have sex with men and many of the patients were also infected with other STIs, particularly with HIV,” says Professor Catherine Ison from the Health Protection Agency Centre for Infections in London.
Until recently doctors saw very few cases of lymphogranuloma venereum in the UK, Europe and other developed countries. The disease is caused by certain strains of the bacterium Chlamydia trachomatis and required new diagnostic tests, that had previously not been available in the UK, before the outbreak could be detected.
Bacteria evolve all the time, and the new sexually transmitted bacterial diseases including this new variant of Chlamydia trachomatis are presenting fresh challenges in diagnosis to medical support teams.
“Microbiologists want to be more proactive in helping patients with STIs,” says Professor Ison. “We have made advances in diagnosis by using molecular tests such as the nucleic acid amplification tests (NAATs) which give us a more accurate results, faster turnaround times and can be used with non-invasive samples. These tests can be used for screening in specialised sexual health care clinics and in primary care. However they need to be carefully validated before use.”
“While the advances in technology have enabled progress in many areas, the new tests should only be used by experts who understand their advantages and disadvantages and can interpret the test results properly”, says Professor Ison. “We are very concerned that some of the new tests are being offered for sale over the internet, for home use, when they should really only be used in clinics”.

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...
