    Google and other search engines have changed the way we use the Internet, putting vast sources of information just a few clicks away. But Lindsley professor of psychology Daniel Wegner’s recent research proves that websites—and the Internet—are changing much more than technology itself. They are changing the way our memories function. Wegner’s latest study, “Google Effects on Memory: Cognitive Consequences of Having Information at Our Fingertips,” shows that when people have access to search engines, they remember fewer facts and less information because they know they can rely on “search” as a readily available shortcut.

    Slow waves are generated by the middle frontal lobe, and as this region deteriorates with age, the elderly tend to lose the ability to experience long REM sleep University of California, Berkeley, scientists have found a connection between the amount of sleep one gets in their old age and the quality of their memory. The UC Berkeley team, led by Matthew Walker, believes that forgetfulness in old age may be attributed to a lack of deep, non-rapid-eye-movement (REM) sleep. According to the study, the slow brain waves produced during deep REM sleep help move memories from the hippocampus (short-term memory storage...

    The brains of older people only appear to slow down because they have so much information to compute, much like a full-up hard drive, scientists believe. Older people do not decline mentally with age, it just takes them longer to recall facts because they have more information in their brains, scientists believe. Much like a computer struggles as the hard drive gets full up, so to (sic) do humans take longer to access information, it has been suggested. Researchers say this slowing down it is not the same as cognitive decline. “The human brain works slower in old age,” said...

    Middle-aged men who drink the equivalent of two and a half pints a day risk speeding up memory loss and mental decline by six years, researchers have warned. A 10-year study of more than 7,000 male and female civil servants found men who regularly drank significant amounts of alcohol suffered notable mental decline. The study was reported in the journal Neurology. In contrast men who drank less than one and a half pints a day, or a glass and a half of wine suffered no impact on mental ability. The heaviest drinkers were found to have the equivalent memory of...

    Coffee has long been a friend of students working through the night, but it does more than just keep us awake. A study provides the first convincing evidence that caffeine enhances long-term memory in people – provided the dose is right. The effects mirror similar results seen in honeybees, where a boost to memory from caffeine-laden nectar may help bees return to certain plants. Researchers strongly suspected that caffeine enhances memory, but studies that tried to show this in people weren't conclusive, as any apparent benefits in memory could have been due to increased attention, a known benefit of caffeine....

    Teenage pot smokers could be damaging brain structures critical to memory and reasoning, according to new research that found changes in the brains of heavy users. Research released Monday in the journal Schizophrenia Bulletin showed the brains of young heavy marijuana users were altered in so-called sub-cortical regions — primitive structures that are part of the memory and reasoning circuits. And young people with such alterations performed worse on memory tests than non-using controls, despite the fact that the heavy users had not indulged for more than two years, on average, before the testing.

    It’s an inconvenient truth of aging: In our 30s and up, it gets increasingly harder for most of us to recall names, faces, and details from the past. Scientists have long debated whether this gradual decline is an early form of Alzheimer’s disease—a neurodegenerative condition that leads to severe dementia—or a distinct neurological process. Now, researchers have found a protein that distinguishes typical forgetfulness from Alzheimer’s and could lead to potential treatments for age-related memory loss. Previous studies have shown that Alzheimer’s disease and age-related memory loss involve different neural circuits in the hippocampus, a seahorse-shaped structure in the brain...

    In the new study, the team from Harvard randomly assigned 60 elderly people to drink two cups of flavanol-rich or flavanol-poor cocoa every day for a month. There weren't any overall differences between the high- and low-flavanol groups in terms of cognitive abilities, so the researchers looked a little deeper. They found that people who had compromised blood flow to the brain and white matter damage at the beginning of the study did show a difference after drinking the cocoa for a month: Blood flow in their brains improved by about 8%, and the time it took them to complete...

    Hardware makers often sing the praises of their latest and greatest flash memory, but the folks at Crossbar are ready to show them up with resistive RAM (RRAM) that they've been quietly working on. Compared to NAND, RRAM comes in at half the size and boasts 20 times faster write speeds (140MB/s), reads data at 17MB per second, guzzles 20 times less power and has 10 times more endurance. Since RRAM is non-volatile memory, it can keep data even when it's powered off, á la NAND. As if that weren't enough, 3D stacking construction allows for several terabytes of storage,...

    Researchers manipulate mouse neurons to create a false memory; the work could lead to a better understanding of how memories form. Remember this: The red neurons are the brain cells in the hippocampus of a mouse carrying a new memory of a particular place. Scientists have created a false memory in mice by manipulating neurons that bear the memory of a place. The work further demonstrates just how unreliable memory can be. It also lays new ground for understanding the cell behavior and circuitry that controls memory, and could one day help researchers discover new ways to treat mental illnesses...

Researchers at HGST, a major manufacturer of hard disk drives, have shown that an emerging fabrication technology called nano-imprinting could be used to double the data storage capacity of today’s hard disks. They say the patent-pending work, done in collaboration with a company called Molecular Imprints, could lead to a cost-effective manufacturing process by the end of the decade. Hard disk drives store data in magnetic material on the surface of a spinning disk. During production, this material is deposited as...

A technique that enables the nanopatterned layers that store data in hard disk drives to assemble themselves has been improved to better suit mass production, and could enable disks that store five times as much data as the largest available today. Using self-assembly instead of machines that print or etch out features has long been considered a potential solution to a looming barrier to expanding the capacity of hard-disk designs.

    Researchers working at MIT have successfully manipulated the content of a rat's dream by replaying an audio cue that was associated with the previous day's events, namely running through a maze (what else). The breakthrough furthers our understanding of how memory gets consolidated during sleep — but it also holds potential for the prospect of "dream engineering." Working at MIT's Picower Institute for Learning and Memory, neuroscientist Matt Wilson was able to accomplish this feat by exploiting the way the brain's hippocampus encodes self-experienced events into memory. Scientists know that our hippocampus is busy at work replaying a number of...

    We've all experienced it: The frustration of entering a room and forgetting what we were going to do. Or get. Or find. New research from University of Notre Dame Psychology Professor Gabriel Radvansky suggests that passing through doorways is the cause of these memory lapses. "Entering or exiting through a doorway serves as an 'event boundary' in the mind, which separates episodes of activity and files them away," Radvansky explains. "Recalling the decision or activity that was made in a different room is difficult because it has been compartmentalized." The study was published recently in the Quarterly Journal of Experimental...

Incorporating graphene could help extend the viability of flash memory technology for years to come, and allow future portable electronics to store far more data. Chipmakers pack increasing amounts of data in the same physical area by miniaturizing the memory cells used to store individual bits. Inside today's flash drives, these cells are nanoscale "floating gate" transistors. Recent years have seen the...

    Even long after it is formed, a memory in rats can be enhanced or erased by increasing or decreasing the activity of a brain enzyme, say researchers supported, in part, by the National Institutes of Health. "Our study is the first to demonstrate that, in the context of a functioning brain in a behaving animal, a single molecule, PKMzeta, is both necessary and sufficient for maintaining long-term memory," explained Todd Sacktor, of the SUNY Downstate Medical Center, New York City, a grantee of the NIH's National Institute of Mental Health. Sacktor, Yadin Dudai, Ph.D., of the Weizmann Institute of Science,...
  • Researchers discover how to erase memory (my question: can it be weaponized?)

    (PhysOrg.com) -- Researchers working with mice have discovered that by removing a protein from the region of the brain responsible for recalling fear, they can permanently delete traumatic memories. Their report on a molecular means of erasing fear memories in rodents appears this week in Science Express. “When a traumatic event occurs, it creates a fearful memory that can last a lifetime and have a debilitating effect on a person’s life,” says Richard L. Huganir, Ph.D., professor and director of neuroscience at the Johns Hopkins University School of Medicine and a Howard Hughes Medical Institute investigator. “Our finding describing these...

    Can you imagine remembering every single day of your life? That's what actress Marilu Henner says she can do. On "The Early Show" Monday, Henner -- one of only six people recognized in the world as having a rare gift called superior autobiographical memory -- explained what life is like remembering every day of her life. Henner and others with the same ability were profiled Sunday on "60 Minutes."
  • Taking Early Retirement May Retire Memory, Too

    The two economists call their paper “Mental Retirement,” and their argument has intrigued behavioral researchers. Data from the United States, England and 11 other European countries suggest that the earlier people retire, the more quickly their memories decline. The implication, the economists and others say, is that there really seems to be something to the “use it or lose it” notion — if people want to preserve their memories and reasoning abilities, they may have to keep active. “It’s incredibly interesting and exciting,” said Laura L. Carstensen, director of the Center on Longevity at Stanford University. “It suggests that work...
  • Compound in celery, peppers reduces age-related memory deficits

    CHAMPAIGN, lll. — A diet rich in the plant compound luteolin reduces age-related inflammation in the brain and related memory deficits by directly inhibiting the release of inflammatory molecules in the brain, researchers report. Luteolin (LOOT-ee-oh-lin) is found in many plants, including carrots, peppers, celery, olive oil, peppermint, rosemary and chamomile. The new study, which examined the effects of dietary luteolin in a mouse model of aging, appears in the Journal of Nutrition. The researchers focused on microglial cells, specialized immune cells that reside in the brain and spinal cord. Infections stimulate microglia to produce signaling molecules, called cytokines, which...

    Every September, millions of parents try a kind of psychological witchcraft, to transform their summer-glazed campers into fall students, their video-bugs into bookworms. Advice is cheap and all too familiar: Clear a quiet work space. Stick to a homework schedule. Set goals. Set boundaries. Do not bribe (except in emergencies). And check out the classroom. Does Junior’s learning style match the new teacher’s approach? Or the school’s philosophy? Maybe the child isn’t “a good fit” for the school. Such theories have developed in part because of sketchy education research that doesn’t offer clear guidance. Student traits and teaching styles surely...

    Recently I upgraded the memory on my computer. It runs Windows Vista and was slow with only 1 gigabyte of memory. I had been told that 2 gigabytes were the minimum for optimum function, but I was lazy. Inertia is a property of matter, but regrettably it is also a property of people. Finally I upgraded the memory to 2 gigabytes. Everything is faster, including word processing and Web surfing. Human beings are not computers − except for bureaucrats, that is. But if we stumble along with inadequate memory, everything we do is less efficient. In particular, our knowledge of...

    SAN FRANCISCO — It’s 1 p.m. on a Thursday and Dianne Bates, 40, juggles three screens. She listens to a few songs on her iPod, then taps out a quick e-mail on her iPhone and turns her attention to the high-definition television. Just another day at the gym. As Ms. Bates multitasks, she is also churning her legs in fast loops on an elliptical machine in a downtown fitness center. She is in good company. In gyms and elsewhere, people use phones and other electronic devices to get work done — and as a reliable antidote to boredom. Cellphones, which...

    FINDING it difficult to revise for an exam? Help could be on its way in the form of the first non-invasive way of stimulating the brain that can boost visual memory. The technique uses transcranial direct current stimulation (tDCS), in which weak electrical currents are applied to the scalp using electrodes. The method can temporarily increase or decrease activity in a specific brain region and has already been shown to boost verbal and motor skills in volunteers. Richard Chi, a PhD student at the Centre for the Mind, University of Sydney, and colleagues wanted to follow up on previous research...

    I need some advice for a friend of mine from my church. Since none of you know where I go or who he is, I can protect his anonymity. He doesn't know I'm doing this. He seemed a bit upset at church this weekend, so I asked what happened. Here's what he told me: Last Tuesday, he was on Facebook. He noticed that he'd received a private message from someone he'd 'friended' about a month earlier. This woman was a high-school acquaintance, one of several he's added to his friend list in anticipation of his 30-year high school reunion coming...
