Speaking two languages benefits the aging brain New research reveals that bilingualism has a positive effect on cognition later in life. Findings published in Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society, show that individuals who speak two or more languages, even those who acquired the second language in adulthood, may slow down cognitive decline from aging.
Nearly 1 in 8 American children are maltreated before age 18 By the time they reach age 18, about 12% of American children experience a confirmed case of maltreatment in the form of neglect, physical, sexual, or emotional abuse, according to a new study by researchers at Yale University. The numbers are even more sobering for black and Native American children, with one in five black
Study finds that suicides are far more likely to occur after midnight A new study provides novel evidence suggesting that suicides are far more likely to occur between midnight and 4 a.m. than during the daytime or evening. Results show that the weighted, scaled mean suicide rate per hour was 10.27 percent after midnight, peaking at 16.27 percent between 2 a.m. and 2:59 a.m.  In contrast, the
Shining a light on memory: It’s all about strengthened connections between neurons Using a flash of light, scientists have inactivated and then reactivated a memory in genetically engineered rats. The study, supported by the National Institutes of Health, is the first cause-and-effect evidence that strengthened connections between neurons are the stuff of memory. “Our results add to mounting evidence that the brain represents a memory by forming
Researchers learn how to erase a memory — and restore it Researchers at the University of California, San Diego School of Medicine have erased and reactivated memories in rats, profoundly altering the animals’ reaction to past events. The study, published in the June 1 advanced online issue of the journal Nature, is the first to show the ability to selectively remove a memory and predictably reactivate it
Neuron tells stem cells to grow new neurons Duke researchers have found a new type of neuron in the adult brain that is capable of telling stem cells to make more new neurons. Though the experiments are in their early stages, the finding opens the tantalizing possibility that the brain may be able to repair itself from within. Neuroscientists have suspected for some
Marijuana use is associated with impaired sleep quality A new study suggests that marijuana use is associated with impaired sleep quality. Results show that any history of cannabis use was associated with an increased likelihood of reporting difficulty falling asleep, struggling to maintain sleep, experiencing non-restorative sleep, and feeling daytime sleepiness. The strongest association was found in adults who started marijuana use before
Study links evening blue light exposure to increased hunger A new study suggests that blue-enriched light exposure immediately before and during the evening meal may increase hunger and alter metabolism. Results show that blue-enriched light exposure, compared with dim light exposure, was associated with an increase in hunger that began 15 minutes after light onset and was still present almost two hours after the
Like some happiness with that? Study suggests fast food cues hurt ability to savor experiences Want to be able to smell the roses? You might consider buying into a neighbourhood where there are more sit-down restaurants than fast-food outlets, suggests a new paper from the University of Toronto’s Rotman School of Management. The paper looks at how exposure to fast food can push us to be more impatient and that
How to Forgive Those Who Have Wronged You Have you ever felt wronged or abused by someone? Everyone at some point or another has felt disappointed in and disillusioned by others’ words or actions. We all create images of specific roles we desire certain people to play in our lives. We long for the comfort of family, friends,...
Sweet Relief from Narcissists The words and markers of love you encounter in a relationship with a narcissist may be present, so you will assume it's "true love." Yet when you encounter contradictory behavior such as disregard or selfishness, you don’t feel the love, and you don’t feel validated or understood. You may wonder, “What is wrong with me?” But it's not you: it's the narcissist.
MRI-guided laser procedure provides alternative to epilepsy surgery For patients with mesial temporal lobe epilepsy (MTLE) that can't be controlled by medications, a minimally invasive laser procedure performed under MRI guidance provides a safe and effective alternative to surgery, suggests a study. The researchers report their experience with MRI-guided SLAH in 13 adult patients with epilepsy mapped to a part of the brain called the mesial temporal lobe. The patients, median age 24 years, had "intractable" seizures despite treatment with antiepileptic drugs.
What to Expect From Your Marriage Couples with ongoing relationship problems may complain bitterly about some aspect of their partner's behavior, yet continue to put up with it for years. Sometimes they will even say that if the relationship improves in the way they are asking for, it will end. The dirty secret is that both of them may actually share a problem, and both are invested in not solving it.
The Original Example Of A Freudian Slip Freudian slips are slips of the tongue that seem to reveal the speaker's secret thoughts. The most famous of these slips, in psychological circles, was analyzed by Sigmund Freud himself. Learn about how Freud connected incorrect Latin to a dark personal secret....
Why inflammation leads to a leaky blood-brain barrier: MicroRNA-155 Until now, scientists have not known exactly how inflammation weakens the blood-brain barrier, allowing toxins and other molecules access to the brain. A new research report solves this mystery by showing that a molecule, called 'microRNA-155,' is responsible for cleaving epithelial cells to create microscopic gaps that let material through.
Can a Classroom Lecture Treat Depression? For all of the treatments available for clinical depression, no single one reliably works for everyone. One person may improve on Wellbutrin, while another finds relief from a therapist. It’s a maddening, time-consuming trial-and-error effort. Worse yet, most people don’t even bother seeking out treatment for their depression. They stumble...
Neuron tells stem cells to grow new neurons: First piece of new brain-repair circuit identified Researchers have found a new type of neuron in the adult brain that is capable of telling stem cells to make more new neurons. Though the experiments are in their early stages, the finding opens the tantalizing possibility that the brain may be able to repair itself from within.
Hypnosis extends restorative slow-wave sleep, research shows Sleeping well is a crucial factor contributing to our physical and mental restoration. Slow-Wave sleep (SWS) in particular has a positive impact for instance on memory and the functioning of the immune system. During periods of SWS, growth hormones are secreted, cell repair is promoted and the defense system is stimulated. If you feel sick or have had a hard working day, you often simply want to get some good, deep sleep, a wish that you may not be able to influence through your own will.  
Moving from Happiness to Joy Last week, in a post called “The Discomfort of Happiness,” I shared some recent experiences I’ve had around feeling happy. Then (in what always proves to be a gutsy move in hindsight) I shared the post with my longtime mentor. Her very first question to me was to ask why...
The Effect of Behaviorism on Sports Suspensions The discussion of Pete Rose’s status in baseball is an old one (just ask Jim Gray). The trend to compare his crime of gambling on baseball to ostensibly more severe crimes is more recent. Joe Posnanski, for example, focuses on the insignificant punishments allotted to NFL players and staff involved in “Bountygate,” which...
