In the study, the researchers examined the association between dietary antioxidant carotenoids and hip fracture risk across a range of BMI in elderly Chinese men and women using data from the Singapore Chinese Health Study. This population-based, cohort prospective study recruited 63,257 men and women aged 45 years between 1993. In this group, a total of 1,630 incident hip fractures up to December 2010 were identified via record linkage with the nationwide hospital discharge database.
Importantly, the study found that low BMI is a stronger risk factor for hip fracture risk among elderly men compared to women.
Also, in men, hip fracture risk decreased with increasing intakes of total vegetables and of total carotenoids, particularly â-carotene. The protective effect was higher in lean men than in men with higher BMI. In contrast, the intake of vegetables or carotenoids had no association with hip fracture risk in women, regardless of levels of BMI.
Cartenoids, which are found many fruits and vegetables (and especially in yellow and orange pigmented vegetables) are converted to vitamin A in the body. The researchers conclude that clinical trials are needed to demonstrate the efficacy of carotenoid supplementation on reduction of hip fracture risk in elderly men. The findings may have important public health implications on hip fracture prevention, particularly among Asians.

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.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
