Psychology of strategic deception revealed by online poker Online poker offers new insights into the mind-set of scheming Machiavellians, researchers have found. Researchers from Lancaster University and the University of Helsinki show that the card betting game can be used as a novel way to better understand the psychology of strategic deception. Before now, the trait has rarely been studied in natural settings [...]
The brain needs cleaning to stay healthy Research led by the Achucarro Basque Center for Neuroscience, the University of the Basque Country (UPV/EHU), and the Ikerbasque Foundation has revealed the mechanisms that keep the brain clean during neurodegenerative diseases. When neurons die, their debris need to be quickly removed in order for the surrounding brain tissue to continue to function properly. Elimination [...]
In brain-injured patients, a way to measure awareness or its impending return The precise diagnosis and prognosis of recovery of consciousness of patients after a severe brain injury is a challenging clinical task, as some brain-injured patients retain certain levels of awareness despite appearing fully unresponsive. Now, researchers reporting in the Cell Press journal Current Biology on May 26 have evidence that readily obtainable measures of the [...]
Can being a good storyteller lead to love? Everyone loves a good story, but can a good story lead to love? Storytelling is a fundamental form of communication, and research has demonstrated the power of narratives to change minds and influence behavior. For example, personal narratives are often used in advertising and health campaigns, and have led to an increase in cancer screenings. [...]
Mothers’ parenting stress impacts both parents’ sexual satisfaction First-time parents are only somewhat satisfied with their sex lives according to Penn State health researchers who checked in with parents regularly after their baby was born. And one factor that appears to be reducing their sexual satisfaction is mothers’ stress as a new parent. “The transition to parenthood has gained importance recently,” said Chelom [...]
Stress affects males, females differently A stress receptor in the brain regulates metabolic responses to stressful situations differently in male and female mice, report researchers. The results could aid in the development of treatments for regulating hunger or stress responses, including anxiety and depression.
Party on(line): The link between social media and alcohol use One of the undeniable powers of social media is its ability to influence people and their behaviors. This is especially true, a Michigan State University study finds, when it comes to alcohol use. MSU researchers found that when participants in a study were exposed to ads touting beer, as opposed to those selling bottled water, [...]
New discovery from the molecular machinery for depression and addiction When nerve cells have to communicate with each other in our brains, it involves release of small signal molecules, the so-called neurotransmitters, which act as chemical messengers in specific points of contact between nerve cells, called synapses. Here the released neurotransmitter is bound and registered by receptors at the surface of the receiving nerve cell. [...]
What’s Your Conflict Style?   People are often defined by how they approach conflict. Take a colleague at work who is terribly submissive and avoids confrontation. They are known as a ‘door mat’ and are treated as such by their colleagues and superiors. On the other hand, there are people who seem to seek out a fight. They raise […]
Study explores why there is no Labor Party in the United States The improbable rise of Bernie Sanders’ presidential campaign presents an interesting question: why is Sanders, a self-proclaimed “democratic socialist,” running as a Democrat? “In any other industrialized country, Sanders would likely be the standard-bearer for a labor or social democratic party,” said McGill University sociologist Barry Eidlin, whose new study appears in the June issue [...]
New technique captures the activity of an entire brain in a snapshot When it comes to measuring brain activity, scientists have tools that can take a precise look at a small slice of the brain (less than one cubic millimeter), or a blurred look at a larger area. Now, researchers at Rockefeller University have described a new technique that combines the best of both worlds–it captures a [...]
For millions on long-term opioid medications, change will be a challenge A team of researchers at the University of Colorado School of Medicine and the VA Eastern Colorado Health Care System recently surveyed patients to understand barriers to reducing the use of opioids to manage chronic pain. The results of those interviews are published in the current issue of the journal Pain Medicine. Millions of Americans [...]
Coping with active surveillance anxiety in prostate cancer Men with prostate cancer who are under medical surveillance reported significantly greater resilience and less anxiety after receiving an intervention of mindfulness meditation, a study found. The anxiety and uncertainty that men who choose active surveillance experience when diagnosed with prostate cancer causes one in four to receive definitive therapies within one to three years, even when there is no sign of tumor progression.
How the brain makes, and breaks, a habit Not all habits are bad. Some are even necessary. But inability to switch from acting habitually to acting in a deliberate way can underlie addiction and obsessive compulsive disorders. Working with a mouse model, an international team of researchers demonstrates what happens in the brain for habits to control behavior.
Fasting-like diet reduces multiple sclerosis symptoms Evidence is mounting that a diet mimicking the effects of fasting has health benefits beyond weight loss, with a new USC-led study indicating that it may reduce symptoms of multiple sclerosis. Scientists discovered that the diet triggers a death-and-life process for cells that appears critical for the body’s repair. “During the fasting-mimicking diet, cortisone is [...]
Neuroscience study identifies how endocannabinoids make and break habits in the brain Not all habits are bad. Some are even necessary. It’s a good thing, for example, that we can find our way home on “autopilot” or wash our hands without having to ponder every step. But inability to switch from acting habitually to acting in a deliberate way can underlie addiction and obsessive compulsive disorders. Working [...]
Why everyone wants to help the sick — but not the unemployed New research from Aarhus BSS at Aarhus University explains why healthcare costs are running out of control, while costs to unemployment protection are kept in line. The answer is found deep in our psychology, where powerful intuitions lead us to view illness as the result of bad luck and worthy of help. Illness and unemployment [...]
