ITN coverage in Kenya has increased rapidly from 7% in 2004 to 67% in 2006. Dr Greg Fegan, KEMRI-Wellcome Trust Research Programme, Kilifi, Kenya and colleagues studied 3500 children aged under-5-years once a year over three years. The children were based in 72 rural clusters in four districts of Kenya.
They found that the estimated rate of mortality in children reported to have used a recently treated bednet was 56% of that for children who did not use an ITN, a protective efficacy of 44%.
The authors say: “Using these estimates of protection, we estimate that the scaling-up of ITN coverage might have averted seven deaths for every 1000 ITNs used. However, there is considerable mortality variation by area – the effects were greatest in areas of reported high malaria transmission.”
They conclude by saying they are confident a substantial effect on child survival was achieved during the expansion phase of the ITN strategy and might have reduced by a third the numbers of childhood deaths in high coverage districts in 2006. They say: “Donor agencies should regard this as money well spent and recognise that the challenge is now to maintain and increase funding to expand coverage further.”
In an accompanying Comment, Professors Christian Lengeler and Don deSavigny, Swiss Tropical Institute, Basel, Switzerland, say: “With this work, the use of insecticide-treated bednets is confirmed as a major child-survival intervention in malaria-endemic settings in sub-Saharan Africa. The ongoing switch to long-lasting insecticidal bednets will further reinforce this intervention.”

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....

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...
