The adage "Fake it until you make it" - the idea that someone can fake a positive attitude to elicit real-life benefits - often backfires when used with co-workers, according to a study led by a University of Arizona researcher.

Instead, researchers say, making an effort to actually feel the emotions you display is more productive.

Allison Gabriel, associate professor of management and organizations in the Eller College of Management, led a team that analyzed two types of emotion regulation that people use at work: surface acting and deep acting.

Children with elevated exposure to early life stress in the home and elevated prenatal exposure to air pollution exhibited heightened symptoms of attention and thought problems, according to researchers at Columbia University Mailman School of Public Health and Columbia Psychiatry. Early life stress is common in youth from disadvantaged backgrounds who also often live in areas with greater exposure to air pollution.

Research conducted at Swansea University and the University of Milan has shown that students who use digital technology excessively are less motivated to engage with their studies, and are more anxious about tests. This effect was made worse by the increased feelings of loneliness that use of digital technology produced.

Clinical trials suggest treatment that involves psychedelics can be more effective than psychotherapy alone.

More than three million people in the United States are diagnosed each year with post-traumatic stress disorder, whose symptoms include nightmares or unwanted memories of trauma, heightened reactions, anxieties, and depression--and can last months, or even years.

Mathematics and science Braille textbooks are expensive and require an enormous effort to produce -- until now. A team of researchers has developed a method for easily creating textbooks in Braille, with an initial focus on math textbooks. The new process is made possible by a new authoring system which serves as a "universal translator" for textbook formats, combined with enhancements to the standard method for putting mathematics in a Web page.

Psychology researchers from HSE University have trialed the reliability of a student engagement scale on 537 Russian primary school students. The findings indicated that the emotional component contributes the most to school engagement. The paper has been published in PLOS ONE journal.

When you expect a really bad experience to happen and then it doesn't, it's a distinctly positive feeling. A new study of fear extinction training in mice may suggest why: The findings not only identify the exact population of brain cells that are key for learning not to feel afraid anymore, but also show these neurons are the same ones that help encode feelings of reward.

Remoras are among the most successful marine hitchhikers, thanks to powerful suction discs that allow them to stay tightly fastened to the bodies of sharks, whales and other hosts despite incredible drag forces while traveling through the ocean. But how do these suckerfish sense the exact moment when they must "stick their landing" and board their speedy hosts in the first place?

A team of biologists at New Jersey Institute of Technology (NJIT), Friday Harbor Labs at University of Washington (FHL-UW) and The George Washington University (GWU) now offers an answer.

The future potential of early stage startups can be assessed by their existing professional relationships, research led by a team at Queen Mary University of London suggests.

Using available online data from 41,380 companies collected over 25 years, the research team created a visual network to show connections between companies and their employees.

They found that young startups who quickly acquire a central position within the network are more likely to show signs of long-term economic success.

Hartford, CT - In a new analysis of studies conducted following the implementation of the 2010 Healthy Hunger Free Kids Act (HHFKA), researchers find positive effects on the dietary quality of meals served to school-aged children.

WASHINGTON-(Jan. 13, 2020)-Knowing that your unborn fetus has congenital heart disease causes such pronounced maternal stress, anxiety and depression that these women's fetuses end up with impaired development in key brain regions before they are born, according to research published online Jan. 13, 2020, in JAMA Pediatrics.

A molecule produced by the brain that activates the same receptors as marijuana is protective against stress by reducing anxiety-causing connections between two brain regions, Vanderbilt University Medical Center researchers report.

CORVALLIS, Ore. - Marijuana use among college students has been trending upward for years, but in states that have legalized recreational marijuana, use has jumped even higher.

An Oregon State University study published today in Addiction shows that in states where marijuana was legalized by 2018, both occasional and frequent use among college students has continued to rise beyond the first year of legalization, suggesting an ongoing trend rather than a brief period of experimentation.

Every language has cases in which two or more concepts are expressed by the same word, such as the English word fly, which refers to both the act of flying and to the insect. By comparing patterns in these cases, which linguists call colexifications, across languages, researchers can gain insights into a wide range of issues, including human perception, language evolution, and language contact.

Chemists have found a new use for the waste product of nuclear power - transforming an unused stockpile into a versatile compound which could be used to create valuable commodity chemicals as well as new energy sources.

Depleted uranium (DU) is a radioactive by-product from the process used to create nuclear energy. Many fear the health risks from DU, as it is either stored in expensive facilities or used to manufacture controversial armour-piercing missiles.
