A new study in medical students finds that summer, not winter, is the season when people are most likely to have higher levels of circulating stress hormones. These non-intuitive findings contradict traditional concepts of the taxing physical toll of winter and the relaxed ease of summer. Researchers will present their findings today at the American Physiological Society (APS) annual meeting at Experimental Biology 2018 in San Diego.
Previous research showed that the combination of two risk factors – parental separation/ divorce and family history of alcoholism (FH+) – can have negative effects on offspring, including an earlier onset of substance use among adolescents and young adults, lower educational attainment in adulthood, and a greater risk of alcohol dependence. This study looked at the impact of parental divorce and FH+ on offspring’s alcohol problems, marijuana use, and interpersonal relationships with parents.
Parents and adults spend a lot of time worrying about the influence of peers when it comes to teen substance use. Using a unique sample of 476 twin pairs who have been followed since birth, a new study examines if there is a genetic component that drives teens’ desire for risk taking and novelty.

Children with emotional and behavioral disabilities are the most isolated and have the lowest graduation rate of all students.One way to ensure better outcomes for these students is to help them learn how to self-regulate their behavior. This is an area in which Lisa Rafferty has focused her research and now relays to the next generation of teachers.
While some research suggests that midlife is a dissatisfying time for women, other studies show that women report feeling less stressed and enjoy a higher quality of life during this period.
How can a company that makes an excellent product — say, really effective software — communicate that quality to the consumer? One way is to set a respectably high price. Another way of "signaling" high quality is to offer a relatively long trial period for the product, according to new research from the University of Washington Bothell School of Business and the University of Texas at Dallas.
Telling job applicants how many people applied for a job on LinkedIn – regardless of whether the number of applicants was high or low – increased the number of applications, a finding that could help companies that are seeking more diverse applicant pools, according to a new analysis from Tufts economist Laura Gee, Ph.D.
Whites in multiracial congregations have more diverse friendship networks and are more comfortable with minorities — but that is more because of the impact of neighbors and friends of other races than due to congregations’ influence, a Baylor University study has found.
Mindfulness meditation programs have shown promise for the treatment of anxiety, one of the most common mental health disorders in the U.S. New research suggests people can begin to derive psychological and physiological benefits from the practice after a single introductory session.
As an undergraduate, Tejaswini Yelamanchili used to spend hours a day playing video games like Counter-Strike and Age of Empires. Time would speed by – hours seemed like minutes – as she focused on the process of gaming. Now a graduate student at Missouri S&T, she’s spending much of her time getting others into gaming as part of her research to better understand how the brain works when players are in the zone.

It might seem surprising that a colony of ants would tolerate the type of guests that gobble both their grub and their babies. But new research shows there’s likely a useful tradeoff to calmly accepting these parasite ants into the fold: They have weaponry that’s effective against their host ants and a more menacing intruder ant.

There’s increasing physiological evidence connecting breathing patterns with the brain regions that control mood and emotion. Now researchers have added neurons associated with the olfactory system to the connection between behavior and breathing. Connecting patterns in these interactions may help explain why practices such as meditation and yoga that rely on rhythmic breathing can help people overcome anxiety-based illnesses.

Both civilians and military veterans with post-traumatic stress disorder (PTSD) reap long-term benefits from psychotherapies used for short-term treatment, according to a new study from Case Western Reserve University.
Scientists have for the first time found direct causal links between the neurotransmitter dopamine and avoidance – behavior related to pain and fear. Researchers have long known that dopamine plays a key role in driving behavior related to pleasurable goals, such as food, sex and social interaction. In general, increasing dopamine boosts the drive toward these stimuli. But dopamine’s role in allowing organisms to avoid negative events has remained mysterious.
Innovators aren’t born, they can be made, according to recent research from the University of California San Diego’s School of Global Policy and Strategy. Existing theories and previous research on how innovation occurs largely assume that it is an ingrained quality of the individual and that only people with this innate ability seek and attain jobs that require it. However, economist Joshua S. Graff Zivin and professor of management Elizabeth Lyons tested these previously held notions by creating a contest for UC San Diego’s engineering and computer science students. The competition, outlined in their National Bureau of Economic Research working paper, was designed to answer the question: Are persuaded innovators less capable than those who naturally gravitate to innovative activities?
Sexual promiscuity is uncommon in America, but a subtle shift has occurred over the past three decades: Men are engaging in such behavior less frequently while more women are sexually adventurous.
it’s not spiders or heights or open spaces. For most people, one of their biggest fears is the prospect of speaking in public. The fear is so deeply rooted that, when surveyed, people will even say they fear public speaking more than death.
A new study shows that individual brain networks are remarkably stable from day to day and while undertaking different tasks, suggesting that finding differences between individuals could help diagnose brain disorders or diseases.

Neurobiology researchers have identified a pathway in brain circuitry that, when stimulated, leads to “antidepressive” behavior in animals. If such brain stimulation proves to have similar effects in people, it may eventually lead to a novel treatment for depression.
With much of the country now entering peak tornado season, the impact of these potentially devastating weather events will be shaped in large part by how individuals think about and prepare for them. A new study published in Risk Analysis shows that people’s past experiences with tornadoes inform how they approach this type of extreme weather in the future, including their perception of the risk.
Many young adults know firsthand that alcohol hangovers are unpleasant. However, few psychometrically sound instruments (tests that accurately measure personality, mental ability, opinions, etc.) have measured hangovers beyond the college-age years. This study investigated the psychometric properties of two interconnected scales – the Hangover Symptom Scale (HSS) and the Hangover Symptom Scale – Short Form (HSS-5) – among a) light and heavy drinkers, b) individuals with a positive or negative family history of an alcohol use disorder (AUD), and c) men and women in a post college-aged sample.
