Omega-3 fatty acid may prevent Alzheimers disease and slow its progression
UCLA neuroscientists have shown for the first time that a diet high in the omega-3 fatty acid DHA helps protect the brain against the memory loss and cell damage caused by Alzheimers disease. The new research suggests that a DHA-rich diet may lower ones risk of Alzheimers disease and may help slow progression of the disorder in its later stages. The journal Neuron reported the findings on Sept. 2. "This is the first proof that our diets affect how our brain cells communicate with each other under the duress of Alzheimers disease," explained Greg Cole, Ph.D., senior author and a professor of neurology at the David Geffen School of Medicine at UCLA. "We saw that a diet rich in DHA, or docosahexaenoic acid, dramatically reduces the impact of the Alzheimers gene.
"Consuming more DHA is something the average person can easily control," added Cole, associate director of the UCLA Alzheimers Disease Research Center. "Anyone can buy DHA in its purified form, fish-oil capsules, high-fat fish or DHA-supplemented eggs."

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
