A team of researchers from the London School of Hygiene & Tropical Medicine, working in partnership with colleagues from Senegal, has found that intermittent preventive malaria treatment of children under five has a dramatic impact on malaria frequency.
In a randomised, placebo-controlled trial, 1,136 children aged between two months and five years received either intermittent preventive treatment, consisting of one dose of artesunate plus one dose of sulfadoxine-pyrimethamine, or two placebos. The preventative treatments were carried out on three occasions during the malaria transmission season, in a health-care centre in Niakhar, a rural area of Senegal.
During thirteen weeks of follow up, the intervention led to an 86% reduction in the frequency of clinical episodes of malaria. The incidence of malaria in children with active drugs was 308 episodes per 1,000 person-years at risk, whereas in controls it was 2,250 episodes per 1,000 person-years at risk. The preventative treatment was safe and did not result in children who had received it experiencing more malaria episodes the following year.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
