tDCS has come a long way from Giovanni Aldini's 1802 pioneering treatment of Luigi Lanzari...

Transcranial direct current stimulation (tDCS) has become a widely used technique for reaching into a person's brain and altering the way in which it functions. Vanderbilt psychology Professor Geoffrey Woodman and graduate student Robert Reinhart have just published the results of a new study in the Journal of Neuroscience in which they found that tDCS stimulation of the mediofrontal cortex for a period of minutes can change one's ability to recognize and learn from error for a period of several hours.  Read More

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.  Read More

A new study carried out at Johns Hopkins University suggests that a moderate dose of caffe...

Caffeine is one the world’s favorite productivity fuels and in many countries people choose a caffeinated drink, mainly coffee, to ignite the day. Although some people rightly worry about over-consuming the stuff, a new study suggests that a moderate daily dosage may enhance our memory.  Read More

Managing magnetism on a nanoscale could provide a big boost for digital storage (Image: Sh...

An international team of scientists has made a breakthrough in the magnetic manipulation of nanoparticles that could lead to a big boost for small scale digital storage in portable devices.  Read More

New MRAM technology could revolutionize data storage in electronic devices (Image: Shutter...

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.  Read More

In a development that may enable a wholly new approach to artificial intelligence, researchers at Harvard University's School of Engineering and Applied Sciences have invented a type of transistor that can learn in ways similar to a neural synapse. Called a synaptic transistor, the new device self-optimizes its properties for the functions it has carried out in the past.  Read More

New research has provided 'strong hope' of finding a drug to combat Alzheimer’s (Image: Sh...

A team of researchers at Yale University has completed a molecular model for Alzheimer's disease by identifying a protein that plays a key role in its onset. Promisingly, the study showed that when the activity of this protein is blocked by an existing drug, mice engineered as models for human AD recover their memories.  Read More

Samsung's 3D Vertical NAND flash memory reads and writes twice as fast as conventional NAN...

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.  Read More

The love hormone has a dark side (Photo: Shutterstock)

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

MIT neuroscientists identified the cells (highlighted in red) where memory traces are stor...

An ongoing collaboration between the Japanese Riken Brain Science Institute and MIT’s Picower Institute for Learning and Memory has resulted in the discovery of how to plant specific false memories into the brains of mice. The breakthrough significantly extends our understanding of memory and expands the experimental reach of the new field of optogenetics.  Read More
