The study, published in PLoS Medicine, by Simon Gregson and colleagues from Imperial College London, randomised different communities in eastern Zimbabwe over a 3 year period. Six pairs of communities in Eastern Zimbabwe were compared, each of which had its own health center.
Control communities received the standard government services for preventing HIV. The other communities received a package of additional strategies including education and condom distribution amongst sex workers and their clients; better services at sexually transmitted infection clinics; and educational HIV/AIDS open days at health centers.
This was a large trial with more than 63,000 meetings being conducted and 7 million condoms distributed by trained peer educators. The researchers found that although male participants benefit ed from the programme with a decrease in incidence of HIV-1, a reduction in reporting of unprotected sex with casual partners, and a decrease in symptoms of sexually transmitted infections, overall there was no change in any of these outcomes for the population at large including the incidence of HIV-1 among the population in general - the main outcome of the trial.
These results are disappointing given the urgent need for control measures for HIV-1 in sub-Saharan Africa. The authors conclude that they “emphasise the need for alternative strategies of behaviour-change promotion.”

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
