Published Reported marital harmony -- or conflict -- accounts for nearly ten percent of the variation in mental health self-assessments in a broad study of Australian adults (via sciencedaily.com) Original source
Australian adults who report a good relationship that meets their original expectations tend to score higher in mental health, while adults who report loving their spouse but wished they had never entered the relationship and note relationship problems tend to score significantly lower in mental health, according to a survey of almost 7000 Australian adults.
Published Low voice pitch increases standing among strangers (via sciencedaily.com) Original source
If you're looking for a long-term relationship or to boost your social status, lower your pitch, according to researchers studying the effects of voice pitch on social perceptions. They found that lower voice pitch makes women and men sound more attractive to potential long-term partners, and lower voice pitch in males makes the individual sound more formidable and prestigious among other men.
Published How a city is organized can create less-biased citizens (via sciencedaily.com) Original source
A new study presents data and a mathematical model to explain why there is more unconscious, or implicit, racial bias in some cities than others. The study, which brings together the math of cities with the psychology of how individuals develop unconscious racial biases, suggests that a city's level of implicit bias depends on how populous, diverse, and segregated that city is.
Published Bullied teens' brains show chemical change associated with psychosis (via sciencedaily.com) Original source
Researchers have found that adolescents being bullied by their peers are at greater risk of the early stages of psychotic episodes and in turn experience lower levels of a key neurotransmitter in a part of the brain involved in regulating emotions. The finding suggests that this neurotransmitter may be a potential target for pharmaceutical interventions aimed at reducing the risk of psychotic disorders.
Published Firing nerve fibers in the brain are supplied with energy on demand (via sciencedaily.com) Original source
To rapidly transmit electrical signals in the brain, the long nerve fibers are insulated by specialized cells called oligodendrocytes. These cells also respond to the electrical signals of active nerve fibers and provide them with energy on demand, as researchers have discovered. If this process, regulated by potassium, is disabled in mice, the nerve fibers are severely damaged as the animals age -- resembling the defects of neurodegenerative diseases.
Published Looking for love? Try finding purpose as well (via sciencedaily.com) Original source
The world of online dating can be overwhelming with the dizzying array of options for attracting a partner but new research shows that those looking for love may have more success if they also seek a sense of purpose in life.
Published Couples: Caring for oneself can lead to happier relationships -- on both sides (via sciencedaily.com) Original source
Being more forgiving of your own shortcomings in a romantic relationship can lead to happier couples. A total of 209 heterosexual couples were surveyed. The results show that men in particular benefit if their partner is self-compassionate. The results provide important information for couples' therapies, as self-compassion can be trained.
Published How does materialism in social media trigger stress and unhappiness? (via sciencedaily.com) Original source
Clothes, cars, travel, followers: People with a materialistic mindset always want more and, above all, more than others. Social media provides them with ideal opportunities to compare themselves with others, which makes them susceptible to passive and addictive user behavior. This stresses them out and, ultimately, leads to low life satisfaction. This downward spiral, which turns materialists into less happy people, was identified in an online survey of over 1,200 participants.
Published Online versus reality: Social media influences perceptions (via sciencedaily.com) Original source
People may form inaccurate impressions about us from our social media posts, finds new research that is the first to examine perceptions of our personalities based on online posts.
Published Vigilant monitoring is needed to manage cardiac risks in patients using antipsychotics, doctors say (via sciencedaily.com) Original source
The use of the antipsychotic drugs quetiapine and haloperidol is associated with an increased risk of ventricular arrhythmias and sudden cardiac death (SCD) caused by drug-induced QT prolongation, reports a new study. Caution is advised to manage cardiac risks in patients prescribed these medications, the authors of the study and an accompanying editorial say.
Published Study reveals function of little-understood synapse in the brain (via sciencedaily.com) Original source
New research for the first time reveals the function of a little-understood junction between cells in the brain that could have important treatment implications for conditions ranging from multiple sclerosis to Alzheimer's disease, to a type of brain cancer known as glioma. Neuroscientists focused on the synapse connecting neurons to a non-neuronal cell, known as oligodendrocyte precursor cells. OPCs can differentiate into oligodendrocytes, which produce a sheath around nerves known as myelin. Myelin is the protective sheath covering each nerve cell's axon -- the threadlike portion of a cell that transmits electrical signals between cells.
Published Clinical predictive models created by AI are accurate but study-specific, researchers find (via sciencedaily.com) Original source
Scientists were able to show that statistical models created by artificial intelligence (AI) predict very accurately whether a medication responds in people with schizophrenia. However, the models are highly context-dependent and cannot be generalized.
Published Science confirms it: Love leaves a mark on the brain (via sciencedaily.com) Original source
The brain produces more of the pleasure-inducing hormone dopamine when we're longing for or hanging out with our partner, new research suggests. But when we break up, their unique 'chemical imprint' fades away. The study centers around prairie voles, which have the distinction of being among the 3 percent to 5 percent of mammals that form monogamous pair bonds.
Published Quest for personalized medicine hits a snag (via sciencedaily.com) Original source
The quest for personalized medicine, a medical approach in which practitioners use a patient's unique genetic profile to tailor individual treatment, has emerged as a critical goal in the health care sector. But a new study shows that the mathematical models currently available to predict treatments have limited effectiveness.
Published Understanding the neuroendocrine basis for social anxiety-like behavior in male mice (via sciencedaily.com) Original source
Researchers have discovered that estrogen receptor (ER), expressed in the lateral septum of the limbic system, plays a crucial role in suppressing anxiety-like behavior exhibited by male mice in social situations. They also discovered that the distribution and expression region of ER differs from that of ER.
Published Love scrambles the brain and scientists can now tell us why (via sciencedaily.com) Original source
Love is blind, the saying goes, and thanks to a new study we are now a step closer to understanding why. Researchers have measured how a part of the brain is responsible for putting our loved one on a pedestal in that first flush of romance.
Published Social media posts may be viewed differently by others to how users perceive themselves (via sciencedaily.com) Original source
In a new study, viewers of Facebook users' posts came away with perceptions of the users that differed from the users' own self-perceptions.
Published Mothers and children have their birthday in the same month more often than you'd think -- and here's why (via sciencedaily.com) Original source
Do you celebrate your birthday in the same month as your mum? If so, you are not alone. The phenomenon occurs more commonly than expected -- a new study of millions of families has revealed.
Published Unravelling the association between neonatal proteins and adult health (via sciencedaily.com) Original source
Scientists studied two complement components that are important parts of the immune system and are linked to schizophrenia and autoimmune disorders. They studied the link between two protein concentrations -- C3 and C4 -- in over 68,000 newborn babies and the risk of developing six mental disorders later in life.
Published Is age linked to the picture of the perfect partner? (via sciencedaily.com) Original source
How do women picture the partner of their dreams? And how does this vary between women based on their age? A team of researchers has investigated the complex relationships between age and preferences for a partner in a large, international sample of single women. The study found that most preferences for a partner showed no variation between women of different ages. However, higher age was linked to a preference for confident and assertive partners, as well as acceptance of a larger age range, in particular a higher acceptance of a partner being younger than oneself. Age was also linked to the parenting intentions of the ideal partner: consistently high in importance until approximately age 28 and then decreasing thereafter.
