Europe is going to the Moon for the first time! In just over two weeks the European Space Agency’s (ESA) lunar probe, SMART-1, begins its journey to the Moon. Due to be launched from Kourou in French Guiana on 3rd September (12.04 a.m. 4th September BST) SMART-1 will be powered only by an ion engine which Europe will be testing for the first time as the main spacecraft propulsion. Onboard will be D-CIXS, an X-ray spectrometer built by scientists in the UK, which will provide information on what the Moon is made of.
SMART-1 represents a new breed of spacecraft. It is ESA’s first Small Mission for Advanced Research in Technology – designed to demonstrate innovative and key technologies for future deep space science missions. As well as the ion propulsion mechanism SMART-1 will test miniaturised spacecraft equipment and instruments, a navigation system which in the long term will allow spacecraft to autonomously navigate through the solar system, and a space communication technique whereby SMART-1 will establish a link with the Earth using a laser beam.
Once it has arrived at the Moon (expected to be in January 2005), SMART-1 will perform an unprecedented scientific study of the Moon– providing valuable information which will shed light on some of the unanswered questions. The spacecraft will search for signs of water-ice in craters near the Moon’s poles, provide data on the still uncertain origin of the Moon and reconstruct its evolution by mapping and the surface distribution of minerals and key chemical elements.

Strathclyde-led research develops world's highest gain high-power laser amplifier
29.05.2017 | University of Strathclyde
The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
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...
