Psychologists at the University of Sussex have found a link between depression and an acceleration of the rate at which the brain ages. Although scientists have previously reported that people with depression or anxiety have an increased risk of dementia in later life, this is the first study that provides comprehensive evidence for the effect of depression on decline in overall cognitive function (also referred to as cognitive state), in a general population.
TAMPA, Fla. (May 23, 2018)- Music can be the ultimate mood setter. Faster beats ignite excitement, while slower songs help one relax. And that makes all the difference in what we order from restaurant menus.
Not long ago, cannabis growers learned their trade mainly by trial and error, passing along tips to others behind a veil of secrecy. But with expanding legalization of cannabis in the U.S., this situation is changing. According to an article in Chemical & Engineering News (C&EN), the weekly news magazine of the American Chemical Society, cannabis growers are starting to benefit from increased communication and scientific research about the plant and its cultivation.
A new Presidential Studies Quarterly article analyzes the effects of the early Trump Presidency on public attitudes toward the Republican Party.
Survey data indicate that Trump appears to be widening the demographic and cultural differences between ordinary Republicans and Democrats, exacerbating the gender, age, and racial gaps between the party coalitions in a way that threatens the long-term vitality of his party.

With summer coming, it's only a matter of time before the smells and tastes of barbecued foods dominate the neighborhood. But there's a downside to grilling that can literally get under your skin. In a study appearing in Environmental Science & Technology, scientists report that skin is a more important pathway for uptake of cancer-causing compounds produced during barbecuing than inhalation. They also found that clothing cannot fully protect individuals from this exposure.
PROVIDENCE, R.I. [Brown University] -- Most renderings and reconstructions of pterodactyls and other extinct flying reptiles show a flight pose much like that of bats, which fly with their hind limbs splayed wide apart. But a new method for inferring how ancient animals might have moved their joints suggests that pterosaurs probably couldn't strike that pose.
Despite stereotypes that paint millennials as "all technology, all the time," young people may still prefer curling up with a paper book over their e-reader -- even more so than their older counterparts -- according to a new study from the University of Arizona that explores consumers' psychological perceptions of e-book ownership.
The study also found that adult consumers across all age groups perceive ownership of e-books very differently than ownership of physical books, and this could have important implications for those in the business of selling digital texts.
Believe it or not -- it's in our nature to cooperate with one another, even when cheating may be more profitable. Social cooperation is common in every scale of life, from the simplest bacterial films and multicellular tissues to insect colonies and nation-states, where individuals prioritize the common good over personal gain, even when the two might conflict. Scientists have long wondered how social cooperation could evolve and persist, since "survival of the fittest" often favors cheaters that multiply at the expense of others.
