A potent antioxidant abundant in apples and some other fruits and vegetables appears to protect brain cells against oxidative stress, a tissue-damaging process associated with Alzheimer’s and other neurodegenerative disorders, according to a new study in rat brain cells conducted by researchers at Cornell University in New York.
The study adds strength to the theory — bolstered by recent animal studies — that the risk of developing Alzheimer’s and similar diseases may be reduced by dietary intervention, particularly by increasing one’s intake of antioxidant-rich foods. It is scheduled to appear in the Dec. 1 issue of the Journal of Agricultural and Food Chemistry, a peer-reviewed publication of the American Chemical Society, the world’s largest scientific society. “On the basis of serving size, fresh apples have some of the highest levels of [the antioxidant] quercetin when compared to other fruits and vegetables and may be among the best food choices for fighting Alzheimer’s,” says study leader C.Y. Lee, Ph.D., professor and chairman of the Department of Food Science & Technology at Cornell University in Geneva, N.Y.
“People should eat more apples, especially fresh ones,” Lee says. He cautions that protection against Alzheimer’s using any food product is currently theoretical and adds that genetics and environment are also believed to play a role in the disease. Despite these caveats, the researcher predicts that “eating at least one fresh apple a day might help.” But Lee also points out that results so far are limited to cell studies and that more advanced research, particularly in animals, is still needed to confirm the findings. Previously Lee and his associates have shown that apples may help protect against cancer too.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
