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.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
