Age-related cataract, the world’s leading cause of blindness, affects more than 20 million Americans over the age of 40 years. Surgical correction is currently the only known option for intervention, but researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University recently sought, in three different studies, to determine if prevention is possible. Their findings suggest that vitamins and polyunsaturated fatty acids--two categories of nutrients believed to have health benefits--may both affect cataract development, although not necessarily in beneficial ways.
In one study, lead scientist Paul Jacques, DSc, director of the Nutritional Epidemiology Program at the Center, and his colleagues analyzed the diets and examined the eyes of a group of Boston-area women over the course of five years. Among the study participants, who were all members of the larger Nurses’ Health Study, women who reported supplementing their diets with vitamin E (a powerful antioxidant) for 10 years or more had significantly less progression of cataract development at the five-year follow-up exam. A similar relative decrease in cataract progression was seen in women who reported higher intakes of two of the B vitamins, riboflavin and thiamin, when compared to women with lower intakes.

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.
