So if you are one of the bodybuilders, powerlifters, marathon runners, or just people who like to binge-eat every now and then — no judgment all you can eat pizza day is a thing I’m told telling myself — there is some bad news. If you like to preload carbs like they are the magic bullet to your workout woes, you may want to rethink it because according to a new study, it can have an acute and detrimental effect on heart function.

This view has been challenged by the University of Southampton researchers Constantine Sedikides and Tim Wildschut, who have spent the past decade studying the benefits of nostalgia. Not only do they disavow its disease status, they have conducted numerous studies which suggest that nostalgia can make us more creative, open-minded and charitable. The definition of nostalgia used by Sedikides and Wildschut as a "sentimental longing for one's past" is based on the contemporary usage........ Read more »

Do you haet typos? If you spot a grammo (a grammatical error), does your blood boil?
Some people are more offended by these kinds of linguistic errors than others, but why? Ann Arbor psychologists Julie E. Boland and Robin Queen examine this in a new PLOS ONE paper called If You’re House Is Still Available, Send Me an Email: Personality Influences Reactions to Written Errors in Email Messages

In today’s lexicon, the term mental illness is used pretty widely. It can be used to describe someone suffering from depression, to PTSD, to even someone suicidal. In fact, today it is sort of a catch all term for anyone who is involved in a mass shooting here in the US. We are getting off […]... Read more »

I believe we all have already experienced this: The same concept can sometimes be defined in very different ways by different authors.

It’s well established that religious people tend to volunteer more and give more to charity than the non-religious. There are many factors that could contribute to this. Many charities that explicitly to support co-religionists or to promote religion, and what’s more religious people also tend to be older and married, both of which predict But [Read More...]...

It was a clear case of a false alarm, toxoplasmosis, a parasite that infects mice and cats was thought to have an effect on humans. However, after a thorough review of the data it was off the hook, or so we thought. Individuals with a psychiatric disorder involving recurrent bouts of extreme, impulsive anger--road rage, for example--are more than twice as likely to have been exposed to a common parasite than healthy individuals with no psychiatric diagnosis.

Think your DNA is all human? Think again. And a new discovery suggests it’s even less human than scientists previously thought. Nineteen new pieces of non-human DNA — left by viruses that first infected our ancestors hundreds of thousands of years ago — have just been found, lurking between our own genes.

Why humans and other animals sleep is one of the remaining deep mysteries of physiology. One prominent theory in neuroscience is that sleep is when the brain replays memories "offline" to better encode them ("memory consolidation"). A prominent and competing theory is that sleep is important for rebalancing activity in brain networks that have been perturbed during learning while awake.

A new study is the first to report that the relationship between nightmares and suicidal behaviors is partially mediated by a multi-step pathway via defeat, entrapment, and hopelessness. Results show that suicidal thoughts, plans or attempts were present in 62 percent of participants who experienced nightmares and only 20 percent of those without nightmares.

They say that once you’ve learned to ride a bicycle, you never forget how to do it. Unfortunately for students who hope this applies to studying, they might not like new research suggesting that while learning, the brain is actively trying to forget. While this may at first blush seem like a bad thing, it actually may be useful for those suffering from PTSD.

Hong Kong and Japanese teachers appear to be more attentive to the processing demands of relational comparisons than are U.S teachers.

Demonstrating the potential of precision medicine, an international study used next-generation DNA sequencing technology to identify more than 1,000 gene variants that affect susceptibility to systemic lupus erythematosus (SLE). Precision medicine is an emerging field that aims to deliver highly personalized health care by understanding how individual differences in genetics, environment, and lifestyle impact health and disease.

(Also appeared on United Academics Magazine) Once upon a time, around 6 000 years ago, there lived a blacksmith.

So he called forth […]... Read more »

By Maggie NannenhornIf you’re like me, you never truly realize how quiet winter is until all the sounds of spring come back in a chorus of celebration. Between the birds, crickets, and frogs, you can really hear the love in the air. So you can hear the love, but can you feel the love? Wood frogs are known for their chorus of calls that sound like a duck laughing.
