Compound in fruits and vegetables prevents symptoms of Alzheimer's disease in mice

Alzheimer's disease represents the most common form of dementia, with the early stages of the disease generally characterized with short term memory loss and learning difficulties that increase in severity as the patient progresses in age. Scientists at the Salk Institute for Biological Studies, California, have discovered that with regular treatments of the antioxidant fisetin, they were able to prevent memory loss in mice with genetic mutations linked to Alzheimer's.

New MRAM technology promises memorable consumer electronics experience

Back in 2005, Professor of Physics Johan Åkerman touted magnetoresistive random access memory (MRAM) as a promising candidate for a "universal memory" that could replace the various types of memory commonly found alongside each other in modern electronic devices. A team of researchers from the National University of Singapore (NUS) and Saudi Arabia's King Abdullah University of Science and Technology (KAUST) has now developed a new type of MRAM that could see Åkerman's vision become a reality.

Samsung moves into mass production of 3D flash memory

Samsung has announced production of the first solid state drives (SSD) based on its new 3D V-NAND flash memory. V-NAND flash memories read and write twice as fast as conventional NAND memories, and last 10 times longer while consuming 50 percent less power. At present, the 3D chips offer about the same physical bit density as do more conventional NAND flash memory chips, but while 2D geometries are reaching the end state of their scaling potential, the 3D chips offer as much as two orders of magnitude of additional elbow room for denser devices.

The two faces of the "love hormone"

Often called the love hormone, oxytocin has shown the ability to enhance social bonding, decrease anxiety and encourage an overall feeling of satisfaction with life. A new study out of Northwestern University, however, finds that this ancient hormone has a dark side, and is capable of strengthening unpleasant memories, fear, and anxiety. This Jeckyll and Hyde behavior results from the fact that oxytocin has a general strengthening effect on social memories, without regard to their polarity. Read More
