Joint hypermobility and links to psychiatry

by Paul Whiteley in Questioning Answers

"The relationship between JH/HDCT [joint hypermobility / heritable disorders of connective tissue] and mental disorders merits further attention in order to improve current knowledge and clarify a possible common etiology."There is nothing in the desert and no man needs nothing.That was the conclusion reached in the paper by Carolina Baeza-Velasco and colleagues [1] looking at the possibility of some interesting connections, outside of just physical presentation, when it come........

Know your brain: Pituitary gland

by neurosci in Neuroscientifically Challenged







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 »

December 18, 2014

by Erin Campbell in HighMag Blog

You might not want the dreaded tube socks in your Christmas stocking this year, but you do appreciate the actual tubes that your body depends on in just about every organ system. A recent paper in PLOS Biology describes tube formation in the fly renal system and the signals that regulate it. Tubes generally start as buds that dramatically elongate during development, but the cell rearrangements that occur during tubulogenesis are not completely understood. Saxena and colleagues recently used th........ Read more »

Why “fat shaming” makes the problem worse

by Gabriel in Lunatic Laboratories

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 »

The Chemistry of Christmas

by Melissa Chernick in Science Storiented

What are the sights, the sounds, the smells, and the textures that you associate with Christmas? Perhaps it is Christmas trees with their lovely green shape, color and wonderful pine smell. Maybe it’s the smells of cooking, the savory smells of turkey or the sweet smell of warm cookies. Or what about all of the cozy feelings you get with big sweaters or a roaring fire? Did you know that there is a lot of chemistry that goes into all of the senses we associate with this holiday?I was browsing t........ Read more »

Dogs Not Great at Math (Wolves Are Better)

by Elizabeth Preston in Inkfish



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 »

Mom, where do birds come from?

Head Motion Biases Brain Structural Scans

by Neuroskeptic in Neuroskeptic_Discover

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.

Fly Life: Watching fruit flies sleep

by Bethany Christmann in Fly on the Wall

Did you know that fruit flies sleep? There are actually a lot of similarities between sleep in fruit flies and sleep in humans and other mammals. For example… Image modified from Colwell, 2007 Like us, fruit flies get most of their sleep at night, and they also have an afternoon slump (although unlike us, they […]... Read more »

The stench of compatibility: How otters identify one another, and potential mates by smelling their poop

by Denise O'Meara in Denise O'Meara

Otters don’t tend to be very visible to us, but they are more abundant than we might perceive them to be. Otters mostly live in isolation of one another, yet they manage to remotely communicate to one another without the aid of modern technology that we so often depend upon for communication.

On this blog, I previously wrote how otters communicate with one another using their spraints (faeces). They use them to mark their territory and to leave messages for other otters. As part of the rese........ Read more »

Uric acid and bipolar disorder

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 [1] 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........

Gene fragments linked to brain development and autism

by Gabriel in Lunatic Laboratories

While the anti-vaccine movement enjoys the simple (and very wrong) answer to the cause of autism, there are people who want the actual truth. This drive had lead to a slew of causes (and risk factors) for autism in recent times. Now scientists have found that very small segments of genes called “microexons” influence how proteins interact with each other in the nervous system. In turn, this opens up a new line of research into the cause of autism.... Read more »

Temperature effects on Calanus finmarchicus vary in space, time and between developmental stages

by sceintists from the Marine group at CEES in Marine Science blog




Increased sea temperature due to climate change can influence the distribution, abundance and seasonal timing of zooplankton. Changing zooplankton dynamics might in turn impact the higher trophic levels, such as fish and seabirds, feeding on these animals. In a recent paper, we show that temperature variation in the Atlantic waters of the Norwegian Sea and Barents Sea might have stronger effects on the abundance of the younger than older development stages of Calanus fin........

Autistic traits in adults with epilepsy
