A paper published in this months PLoS Medicine suggests that combination therapy based on artemisinins (one of the newer antimalarial classes of drug) might not be the ideal treatment for uncomplicated malaria in Africa. If used alone, artemisinins will cure the most severe type of malaria -falciparum malaria -in seven days. However, when used on their own, they have a high risk of the malaria coming back and hence must be combined with other antimalarials to work best. Artemisinins may also slow down development of resistance to the partner drug. But although combinations including artemisinins have been widely advocated, they are expensive and relatively untested in areas where malaria is very frequent.
In a randomised trial conducted at four sites in Uganda, the researchers, led by Grant Dorsey from UCSF, showed that patients treated with a cheaper combination of drugs --amodiaquine and sulfadoxine-pyrimethamine--had at least as good a chance of preventing recurrent malarial infection (defined as either new infections or the previous infection returning) compared with patients treated with artemisinin-based combination therapy. In the sites that had the highest transmission rates the cheaper combination worked better. The authors conclude that although artemisinin combinations offer great hope for Africa, the ideal combination regimen remains uncertain and cost is a problem. To compare the efficacy of the different therapies, bigger and longer controlled trials are needed in many different conditions.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
