"We have to get young people to view condoms as an essential part of having sex," says Ronny Heikki Tikkanen, one of the researchers behind the study which polled 15,000 young people between the ages of 15 and 29 right across Sweden. "The fact that so many don’t use condoms, even though they know that they offer protection against both STIs and unwanted pregnancies, shows how important it is to work on attitudes and behaviour."
The survey clearly demonstrates that those who start having sex at a young age and are generally inclined to take risks with alcohol and drugs are also likely to do so with sex. It is also more common for risk-takers to have accepted payment for sex. Those identified by the study as having exposed themselves to sexual risks have generally encountered HIV prevention initiatives without them having impacted notably on their behaviour.
"We’ve got to get better at identifying youngsters who take risks," says Margareta Forsberg, R&D manager at the Swedish Institute for Communicable Disease Control. “We also need to be more aware of the link between sexual risks, drugs and social exclusion. If we can come up with support structures at an early stage, we stand a better chance of promoting sexual health, self-esteem and wellbeing."
The researchers behind the study are now calling for new methods and strategies for preventive work on sexuality and health for young people.
"Young people want sexual health clinics to be readily accessible, condoms to be distributed at various meeting places and the Internet to be used more widely for advice and support," says Jonna Abelsson, assistant researcher at the University of Gothenburg. "The study offers guidance on the types of initiative that are viable for youngsters. We need to think about whether we’re going about things the right way when it comes to reaching those who most need advice and support."
The Ung KAB09 study is the largest of its kind in Sweden and the large number of respondents means that it has huge potential for increasing our knowledge and for investigating the links between different types of experience. As it was carried out partly through an online questionnaire, the study is not entirely representative, but it still makes an important contribution to preventive work on account of its size.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
