"This pattern of results is consistent with the conceptualisation of a spectrum of disorders, ranging from BDP [bipolar disorder] at one end, to SAD [schizoaffective disorder] in the middle, and SCZ [schizophrenia] at the other end." So concluded the paper by Serafino Mancuso and colleagues  examining clinical data derived from the Australian Survey of High Impact Psychosis (SHIP).The thing about perfection is that it's unknowable.I'm not going to dwell too ........

Who finds Bill Gates' creativity sexy?By guest blogger Sam McNerneyEver since the Sirens seduced Odyssey’s crew, Sophocles entertained ancient Athens, and our Paleolithic ancestors decorated cave walls in Lascaux, individuals have been drawn to acts of creativity. Today, the allure of creativity is all the more apparent. After Tim Berners-Lee created the World Wide Web in 1991, we’ve witnessed a proliferation of creative expression on YouTube channels, blogs, and even Twitter. Given the........ Read more »

There’s one prestigious honor, the Darwin Award, which is given to people that helped improving the human gene pool. However, nobody is really keen on receiving this noble recognition: Darwin Award winners eliminate themselves (or anyway lose their reproductive abilities) in such stupid ways that ensure there’s an idiot less on Earth....

I'm a bit of a fan of tryptophan biochemistry on this blog. This quite remarkable aromatic amino acid and it's off-shoot metabolites, which appear to have no end of biological uses, have taken quite a bit of my blogging time down the years. Most recently was the suggestion that a metabolite slotting in between serotonin (5-HT) and melatonin might require quite a bit more investigation when it comes to at least some cases of autism (see here).See ya later, President Fartfeathers.The findings repo........

Many people are unaware of their mathematics-related abilities, and these abilities have to be considered in their evaluations and life outcomes.

Mathematics is one of the most disliked subjects of students. It is probably due to its logical dealing with the quantity, shape, and arrangements, but interesting part of the life is that many people have no clue about their mathematics-related abilities,........ Read more »

Yes, I know. Another post on the 'day of rest' but I promise you that this will not become a habit. The reason: the paper by Feiyong Jia and colleagues  published in the premier journal Pediatrics. The authors describe a case report of a young child with autism who is observed to have shown improvement in some of the core symptoms of autism following supplementation with the [sunshine] vitamin/hormone of the hour: vitamin D. Further reporting on the paper can be seen here.Altho........ Read more »

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 pituitary gland (in red). Image courtesy of Life Science Databases (LSDB).
Where is the pituitary gland?The pituitary gland is a small (about the size of a pea) endocrine gland that extends from the bottom of the hypothalamus. It is divided into two lobes in humans, the anterior pituitary and posterior pituitary. The anterior pituitary does not have direct neural connections to the hypothalamus, but is able to communicate with it through a system of blo........ Read more »
We usually see worry as a bad thing. It feels unpleasant, like a snake coiling in the pit of your stomach. And worriers are often considered weak links in a team - negative influences who lack confidence. But of course, anxiety has a useful function. It's about anticipating and preparing for threats, and learning from past mistakes.Increasingly psychologists are recognising the strengths of anxious people. For example, there's research showing that people more prone to anxiety are quicker to det........ 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 »

Even a brilliant dog may not be able to count as high as the number of feet she has. In a cheese cube counting challenge, dogs struggled to prove they have any number sense at all. Embarrassingly for the dogs, some wolves took the exact same test and passed it. This may be a hint about what dogs lost when they moved to a cushy life of domestication.
At the Wolf Science Center in Austria, Friederike Range and her colleagues raise both wolves and dogs by hand, then train them to take part i........ Read more »

A regular theme here at Neuroskeptic is the worrying issue of head movement during brain scans. We've seen that motion can alter measures of functional and structural connectivity, and that common approaches to dealing with this problem may be inadequate.
Now a new study reveals that even measures of the gross structure of the brain can be biased by excessive motion: Head motion during MRI acquisition reduces gray matter volume and thickness estimates.

Bipolar disorder appearing again on this blog this week? It's just the way that the papers fall...With a title like: 'Increased uric acid levels in bipolar disorder subjects during different phases of illness' I was hardly likely to pass up the opportunity to discuss the paper by Umberto Albert and colleagues  and their suggestion that there may be a lot more to see when it comes to "a purinergic dysfunction associated with BD [bipolar disorder]".I lost the defuser gun when I mispla........

Teacher training doesn't usually include a module on how to arrange the seating of pupils. Perhaps it should - a new study by psychologists finds that where children are placed in the classroom is associated with how well-liked they are by their classmates.Yvonne van den Berg and Antonius Cillessen studied 34 classrooms at 27 elementary schools in The Netherlands. The 336 participating pupils had an average age of 11, and 47 per cent of them were boys. In all classrooms, it was the school policy........ Read more »
