Will an Optimist Win the Election? Studies have shown that optimistic leaders are perceived to be more effective, and happier people are even judged to be more likely to go to Heaven. But wouldn’t it be nice if psychological scientists could analyze the positivity of presidential candidates and relate it to the outcomes of actual elections? As luck would have it, two U Penn researchers already have.
Happy Thanksgiving With All the Complications Have you noticed that no matter what is going on in your life, the Holidays show up. Ushered in by Thanksgiving, we all know the Hallmark image of the perfect … ...
Could New Facebook Features Help You Get Over Your Ex? Facebook may soon be helping you manage your relationship with your ex by allowing you to limit how much of them you see in your news feed without unfriending or blocking them. Research on coping with break-ups suggests that Facebook has the right idea about how to deal with your ex.
And when the bubbles burst, thunder in neurons In the fleeting moments after a liquid is subjected to a sudden change in pressure, microscopic bubbles rapidly form and collapse in a process known as cavitation. In the human brain, this is believed to be a mechanistic cause of traumatic brain injury, or TBI, but the phenomenon has yet to be directly observed in brain tissue because the bubbles appear and disappear within microseconds. To address this, researchers are seeking to understand how cavitation might injure neurons by using a 3-D imaging system coupled with a diffraction grating to examine their post-exposure morphology.
Loneliness triggers cellular changes that can cause illness, study shows Loneliness is more than a feeling: For older adults, perceived social isolation is a major health risk that can increase the risk of premature death by 14 percent. Researchers have long known the dangers of loneliness, but the cellular mechanisms by which loneliness causes adverse health outcomes have not been well understood. Now a team [...]
Neuroscientists gain insight into cause of Alzheimer’s symptoms Virginia Tech Carilion Research Institute scientists have uncovered a mechanism in the brain that could account for some of the neural degeneration and memory loss in people with Alzheimer’s disease. The researchers, together with scientists at the University of Alabama at Birmingham School of Medicine, discovered that a common symptom of Alzheimer’s disease – the [...]
Online porn may feed sex addicts’ desire for new sexual images People who show compulsive sexual behaviour, commonly referred to as sex addiction, are driven to search more for new sexual images than their peers, according to new research led by the University of Cambridge. The findings may be particularly relevant in the context of online pornography, which potentially provides an almost endless source of new [...]
Post-learning sleep improves the accuracy of remembering face-name associations A new study by investigators at Brigham and Women’s Hospital (BWH) offers an additional reason to get a good night’s sleep. In a closely controlled study of fourteen participants, researchers found that they were significantly better at remembering faces and names if they were given an opportunity to sleep for up to eight hours after [...]

Brain connections predict how well you can pay attention During a 1959 television appearance, Jack Kerouac was asked how long it took him to write his novel On The Road. His response – three weeks – amazed the interviewer and ignited an enduring myth that the book was composed in a marathon of nonstop typing. Like the Kerouac of legend, some people possess the [...]
Children who take ADHD medicines have trouble sleeping, new study shows Stimulant medications for attention-deficit/hyperactivity disorder (ADHD) cause sleep problems among the children who take them, a new study from the University of Nebraska-Lincoln concludes. The study addresses decades of conflicting opinions and evidence about the medications’ effect on sleep. In what’s known as a “meta-analysis,” researchers from the UNL Department of Psychology combined and analyzed [...]
High-fat diet prompts brain immune cells to start eating connections between neurons When a high-fat diet causes us to become obese, it also appears to prompt normally bustling immune cells in our brain to become sedentary and start consuming the connections between our neurons, scientists say. The good news is going back on a low-fat diet for just two months, at least in mice, reverses this trend [...]
New protein biomarker identifies damaged brain wiring after concussion Physicians and others now recognize that seemingly mild, concussion-type head injuries lead to long-term cognitive impairments surprisingly often. A brain protein called SNTF, which rises in the blood after some concussions, signals the type of brain damage that is thought to be the source of these cognitive impairments, according to a study led by researchers [...]
First-of-kind dopamine measurements in human brain reveal insights into how we learn Virginia Tech Carilion Research Institute scientists have reported measurements of dopamine release with unprecedented temporal precision in the brains of people with Parkinson’s disease. The measurements, collected during brain surgery as the conscious patients played an investment game, demonstrate how rapid dopamine release encodes information crucial for human choice. The findings may have widespread implications [...]
Study: Words can deceive, but tone of voice cannot A new computer algorithm can predict whether you and your spouse will have an improved or worsened relationship based on the tone of voice that you use when speaking to each other with nearly 79 percent accuracy. In fact, the algorithm did a better job of predicting marital success of couples with serious marital issues [...]
Toddlers pick up anti-fat attitudes from their mothers, study finds New findings from New Zealand’s University of Otago suggest older toddlers–those aged around 32 months old–are picking up on the anti-fat attitudes of their mothers. The study, involving researchers from New Zealand, Australia, and the US, comes on the back of studies showing that obesity prejudice and discrimination are on the rise. Professor Ted Ruffman, [...]
Sensor provides first real-time, eagle-eye view of neural activity in the brain Researchers at Duke and Stanford Universities have devised a way to watch the details of neurons at work, pretty much in real time. Every second of every day, the 100 billion neurons in your brain are capable of firing off a burst of electricity called an action potential up to 100 times per second. For [...]
Self-Proclaimed Experts Often Claim To Know More Than They Really Do Fifteen years ago, psychologists showed that the most incompetent people are the worst at recognizing their own incompetence, confirming what most of us already suspected. Now it turns out that even highly competent people may lay claim to more knowledge than they actually possess....
