A team of Spanish researchers set out to establish the reference values for skeletal bone status in the course of a human being’s lifetime. This is a “very important piece of work given the changes in bone metabolism of the Spanish population”, Soledad Aguado, the main author of the work and researcher at the UAH explains to SINC.
The research, published in the latest number of the Skeletal Radiology Journal, is the first that has been undertaken in Spain in subjects whose ages ranged from 0 to 80 years of age. The study was performed in 1,120 subjects from the Community of Madrid, all of whom had a sedentary lifestyle.
The sample was divided into 16 groups at 5-year age intervals. Each group had a bone densitometry scan using the technique known as “Dual X-Ray phototonic absorptiometry [DXA]. The aim was to quantify bone mineral content in the whole body and in different and separate areas of the body. The results show that there are big differences in gender in the mean values of bone mineral content for the head and trunk of the body (between 16 and 25 years) and legs and arms (between 16 and 70 years). In all cases, women have less bone mineral content.
Previous studies confirmed that the bone mineral content increases from birth until 25 years of age and reduces from 26 until 40 years of age, the time at which it starts to stabilize. From 56 years old the reduction in bone mineral content becomes more acute. However, women reach their maximum bone mass at an earlier age than men: the increase of total bone mineral content occurs from birth until 20 years of age. The researcher from Madrid explains that these values “offer a useful piece of reference information when comparing them with sedentary populations from other geographical areas, or a population with osteoporosis or sportsmen or women”.
Osteoporosis in Spain
According to the Spanish Society for Bone Research and Mineral Metabolism [la Sociedad Española de Investigación Ósea y Metabolismo Mineral] (SEIOMM), osteoporosis is a disease that affects women more than men. Today two million women already suffer from this disease and it causes about 25,000 bone fractures per year as a result of deterioration in the micro-architecture of bone tissue caused by osteoporosis.
The appearance of this disease is caused mainly by an ageing population and the prevalence of this disease is increasing on a daily basis. Currently, osteoporosis affects 16% of people older than 50 years of age.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
