Exercise Fights Chronic Stress-Dependent Depression

by Agnese Mariotti in United Academics

It is known that physical exercise improves the symptoms of depression. Several hypotheses have been formulated to explain how this occurs, but no clear biochemical mechanism had so far been demonstrated.... Read more »

Brain Imaging In Alcoholic Brain Thiamine Deficiency

by William Yates, M.D. in Brain Posts

Chronic consumption of large quantities of alcohol can produce severe deficiency of thiamine (vitamin B1).This can precipitate an acute brain failure known as Wernicke's encephalopathy. Wernicke's encephalopathy is characterized by sudden onset of mental status changes, eye muscle impairment and disturbed gait or ataxia.Other illnesses can also produce this level of severe thiamine deficiency. A partial list of these non-alcoholism causes for thiamine deficiency with encephalopathy includes........ Read more »

So, potential juror, how much online porn do you watch?

by Doug Keene in The Jury Room

We can hear the snickers and gasps now–and likely the immediate objection from (probably) the opposing counsel or (unquestionably) the judge. But not always. So why might this be something you want to know? According to new research in the Journal of Sex and Marital Therapy, a distinguishing characteristic of narcissists is that they watch […]

Doing the "happy walk" made people's memories more positive

by BPS Research Digest in BPS Research Digest

Walking in a more happy style could help counter the negative mental processes associated with depression. That's according to psychologists in Germany and Canada who used biofeedback to influence the walking style of 47 university students on a treadmill.The students, who were kept in the dark about the true aims of the study, had their gait monitored with motion capture technology. For half of them, the more happily they walked (characterised by larger arm and body swings, and a more upright p........ Read more »

Diagnosing autism late: after psychosis

by Paul Whiteley in Questioning Answers

The case report from Marly Simoncini and colleagues [1] (open-access) is the topic of today's post. Describing the case of Mr. A, a young man who attempted suicide during a psychotic episode, the paper tracks the developmental history and diagnostic evaluation of this person culminating in a diagnosis of autism spectrum disorder (ASD) "that had been completely overlooked".The best thing we can do is go on with our daily routineThe paper is open-access and I would encourage readers to take s........

Using neuroimaging to expose the unconscious influences of priming

by neurosci in Neuroscientifically Challenged

In 1996, a group of researchers at NYU conducted an interesting experiment. First, they had NYU students work on unscrambling letters to form words. Unbeknownst to the students, they had been split up into three groups, and each group unscrambled letters that formed slightly different words. One group unscrambled words with a "rude" connotation like aggressively, bold, and interrupt. Another group unscrambled "polite" words like considerate, patiently, and respect. And the third group unscramble........ Read more »

The Cause Behind Seizures post-Vaccination

by Gabriel in Lunatic Laboratories

The anti-vaccination movement is a dangerous one. Children are falling ill (and in certain cases dying) over nothing more than fear and misinformation. The problem is science doesn’t have all the answers and it is tempting to look to someone — or in this case a group of someones– who claim to have those answers, true or not. Well science eventually gets the answers we need and now scientists have found genetic clues to explain why a small number of children have febrile seizures—brief co........ Read more »

Ebola could mutate as rapidly as the flu

by EE Giorgi in CHIMERAS

© Science MagazineThe largest genomic data collected on the Ebola virus to date has been recently published in Science [1], giving unique insights on the origin and spread of the greatest Ebola outbreak so far. The Ebola virus was first discovered in 1976, when it caused 318 cases: until now, it was the largest outbreak. "The current outbreak started in February 2014 in Guinea, West Africa, and spread into Liberia in March, Sierra Leone in May, and Nigeria in late July. It is the largest known ........ Read more »

Biology and maths partner to understand life decisions

Starting with the one fertilized egg that we all once were, embryonic development is made of cell divisions and most importantly of cell decisions. These first life decisions are the first steps of the development of various cell types, which will further divide, decide, specialize, organize, form specialized organs and ultimately an entire very complex […]...

Stem cells, branching processes and stochasticity in cancer

When you were born, you probably had 270 bones in your body. Unless you’ve experienced some very drastic traumas, and assuming that you are fully grown, then you probably have 206 bones now. Much like the number and types of internal organs, we can call this question of science solved. Unfortunately, it isn’t always helpful […]... Read more »

Fright Week: The Waking Nightmare of Lord Voldemort

Nightmares can seem very real at times, but then we wake up and realize it was all a bad dream. Now imagine having a vivid nightmare with all the reality of waking life and then... it turns out you're actually awake through it all!This happened to an 11 year old Italian boy who reported frightening auditory and visual hallucinations of Voldemort, the archenemy of Harry Potter, for three straight days. These hallucinations began after a bout of sore throat and fever (38°C).  As Vita et........ Read more »

The Oceans Link to Climate Change

by Gabriel in Lunatic Laboratories

Hold on to your hats folks, we can all agree that most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. But in a new study a group of researchers have found that circulation of the ocean plays an equally important role in regulating the earth’s climate. Keep in mind this doesn’t mean global warming isn’t a man-made problem, please.... Read more »

Autism and intolerance of uncertainty

Good morning, gentlemen, the temperature is 110 degrees'Change' is often mentioned as something potentially problematic for many on the autism spectrum, and how unexpected change can sometimes have profound effects in terms of those so-called 'challenging behaviours' or when it comes to the presentation of important comorbidity such as anxiety. Like many others from the outside looking in, I was always taught that change as a more general concept was the important issue in autism, but recently t........ Read more »

The Genetics of Congenital Heart Defects Slowly Emerge from Down Syndrome Study

by Gabriel in Lunatic Laboratories

Down syndrome, of all the genetic defects people are born with, is the most common (as far as chromosomal abnormalities go). Down syndrome involves having a third copy of all or part of chromosome 21 (for those who do not recall we are typically born with 23 pairs of chromosomes). In addition to intellectual disability, individuals with Down syndrome have a high risk of congenital heart defects. However, not all people with Down syndrome have them – about half have structurally normal hearts.... Read more »
