A review of research has revealed striking similarities in the influences on young people’s sexual behaviour across the world.
The review of qualitative studies, published today in The Lancet, looked at 268 studies of the sexual behaviour of under-25-year-olds from South Africa to Sweden. It reveals how, in all countries, social expectations of how men and women should behave frustrate campaigners’ efforts to encourage safer sex.
For example the review found young women often feel their reputation will be sullied if they carry condoms, and young men often feel pressured into having sex when they get the opportunity, whether they have a condom or not. It also found that young people around the world find it hard to even discuss the possibility of sex with potential partners, which makes it difficult to plan condom use.
Other common themes included, for example, a tendency to try and guess the HIV status of potential partners using unreliable indicators such as an individual’s appearance, or how well they know them. Young people are less likely to use condoms if they guess that the partner is ‘clean’.
Dr. Cicely Marston, of LSHTM, who led the review, said it showed why many campaigns to encourage safer sex had failed. ‘Our findings help to explain why many HIV programmes have not been effective’, she said. ‘Giving out condoms and information is vital, but it is not enough. Even where young people know about the importance of condoms, social factors – in particular stereotypes about how men and women should behave and a reluctance to talk openly about sex – hamper their use. Safer sex campaigns need to tackle these issues if they are to succeed’.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
