This has been demonstrated in a thesis at the Sahlgrenska Academy, University of Gothenburg, Sweden based on a study of over 1,000 young adults in Gothenburg, which identified those factors increasing the risk of bone fragility in men.
The thesis of the PhD student Robert Rudäng at the Sahlgrenska Academy, University of Gothenburg, has evaluated how different factors affect skeletal health during adult life.
In the thesis, which is based on studies of just over 1,000 young men in Gothenburg, several previously unknown risk factors for osteoporosis in men were identified:
• men whose maternal or paternal grandfather have suffered a hip fracture have a clearly increased risk of osteoporosis in the form of low bone density and smaller bone size. Compared with men whose maternal or paternal grandfather had not broken their hip, the difference is between 3 to 5 per cent
• the same risk, though not so pronounced, is found in the case of men born of an older mother
• a further risk factor is smoking, whereby the development of bone density in the lumbar region and hip for men who start smoking around 20 is only half as sastisfactory up to the age of 25 or so, when compared with non-smokers
• suffering a fracture in childhood or adolescence has a clear link with microstructure impairment of the skeleton in young adult men, which in the study is shown to contribute to lower skeletal strength of roughly 3 to 4 per cent.
“Previous studies have shown that skeletal health in young adulthood may play a determining role for the risk of suffering osteoporosis and fractures later in life. The studies presented in my thesis identify new risk factors and can hopefully be used to identify, early on, those individuals at risk thereby making it possible to prevent the development of osteoporosis,” states Robert Rudäng.Contact:

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
