Think you know what causes depression? Well unfortunately scientists don’t have the exact answer, surprised? That’s not the only problem, there is an ever growing concern that we live in an over medicated society and a newly released study doesn’t paint a better picture. About 15 percent of women in the United States suffer from anxiety disorders and depression during their pregnancies, and many are prescribed antidepressants. However little is known about how early exposure to these medic........ Read more »

What happens when scientists publish papers that aren't meant to be taken seriously? Is ironic, satirical and joke science all in good fun, or can it be dangerous?
This is the question asked by Drexel University researchers Maryam Ronagh and Lawrence Souder in a new paper is called The Ethics of Ironic Science in Its Search for Spoof.
The British BMJ journal is known for an annual Christmas special issue filled with unusual articles. For example, two years ago they explored the questio... Read more »

Thanks to the internet age we have lost touch with the fact that there is a human out there reading these words. Because of this, the golden rule –treat others the way you want to be treated — went out the window. Making fun of “fat” people now seems to be a internet hobby and that insensitivity can (and does) bleed over into “normal” non-internet life. Now a new study shows that women whose loved ones are critical of their weight tend to put on even more pounds, which is probably no........ Read more »

As December rolls into its second half, and the days warm up - or cool down - depending on where you are situated on the globe, we wanted to say thank you for joining us in 2014 - we are continually blown away with the popular and supportive community we have around us at Do You Believe in Dog? here on the blog, on Facebook and also on Twitter. Taking our lead from Companion Animal Psychology, we decided to jump into some statistics (because hey, we are scientists!) to see wh........ Read more »

We’ve all seen the PSA’s trying to show the effects of meth use and in particular, what it does to your teeth. Typically, when it comes to drug use, people will not look at the long term side effects from their addiction instead thinking in the short term. This is unfortunate because as it turns out, methamphetamine users are three times more at risk for getting Parkinson’s disease than non-illicit drug users with even worse news for women, new research shows....

There is a lot of debate over whether or not violent video games manifest in violent behaviour. Consensus has not entirely been reached, but some suggest that the literature provides solid evidence for the hypothesis in question. In this post I examine meta-analytic reviews of the literature and weigh their significance, coming to the conclusion that violent video games most likely do cause aggressive behaviour and other negative social outcomes....

Ah, the holiday work party. Free food, spending time with people you spend your whole day with already, and enough boozy libations to make things a bit more interesting. Here in North America, many workplaces engage in the gift “game” called the White Elephant Gift Exchange. On this topic, I'm basing today’s post on an article that I recently came across by Gretchen Herrmann in The Journal of Popular Culture where she dissects the Machiavellian nature of this little holiday game.The White ........

In a recent meta-analytic review, I found that working-class students are less integrated at university than their middle-class peers. I offered up nine potential explanations for this working-class exclusion effect. It turns out that one of the simplest explanations in this list is also the most promising. It’s all to do with age.Working-class students tend to be older than middle-class students. Why? Most likely because they don’t tend to go to university immediately after school but i........

Is there a relationship between poetry and psychosis?
The idea that 'genius' is just one step removed from 'madness' is a venerable one, and psychiatrists and psychologists have spent a great (perhaps an inordinate) amount of time looking for correlations between mental illness and creativity.
Now a new British study has examined whether poets exhibit more traits of psychosis than other people. One of the authors is a published poet, Helen Mort.
The researchers recruited 294 poets i... Read more »

Our waistlines are expanding, it’s no secret that around the world despite rampant hunger people are also getting fatter. While there are many things that are contributing to this — our increased food security, the cost of food, fast food, the increasing sugar supplied in food, etc — there are other theories as to why we are getting so heavy. Scientists have pointed towards bacteria, gut microbiota, and many other causes for our increased weight, now add to that list a common hormone that ........ Read more »

Much has been thrown at left-handed people—they are quick to anger, quickly scared and, with the exception of heads of state, are more or less life’s losers. There was even a time where left handedness was “beaten out” of children in school. Conversely, there have been much bestowed upon left-handed people—they are creative and score highly on certain tests. Obviously, scientists need to rely on more than popular notions to make connections, if any, between left-handed people and succe........ Read more »

Solar panels, they are big, heavy, cannot flex, and are still very inefficient. While efficiency isn’t the big issue, flexibility has relegated solar panels to rooftops and solar farms.

How much does global warming really cost the world? Determining the Social Cost of Carbon helps put a actual dollar value on the climate damages per ton of CO2 released, and is used by -- among others -- policymakers to help determine the costs and benefits of climate policies. Remember, even on a global scale, the bottom line will always be profit. But now a group of economists and lawyers urge several improvements to the government's Social Cost of Carbon figure that would impose a regular, tr........ Read more »
