Could flies help us understand brain injuries?

by Dr. Jekyll in Lunatic Laboratories

Each year, an estimated 1.7 million people in the United States sustain traumatic brain injuries (TBIs), according to the U.S. Centers for Disease Control and Prevention. These injuries occur most frequently from falling, but can also result from military combat, car accidents, contact sports or domestic abuse. Recently, physicians and researchers have become increasingly concerned that even mild cases of repetitive brain trauma could have long-term, unanticipated consequences.

Why do women do so much better at university than their school test scores predict?

by BPS Research Digest in BPS Research Digest

Picture an American high school staff-room, late in the academic year, where a teacher called Alice is listening to her colleagues ride their favourite hobby horse: picking out which students have the most promise.Eventually Alice leans forward and taps her laptop. “Less talk, guys, more data. If you want to know how a student will do when they get to college, look at their aptitude test scores.” Betty throws her a look. “That won’t work,” she says, ”girls go on to do better than the........

Vitamin D and autism: the story so far...

by Paul Whiteley in Questioning Answers

I don't want to keep you too long today aside from directing you to the literature review by Hajar Mazahery and colleagues [1] (open-access available here) discussing the collected peer-review literature on the topic of vitamin D and autism to date.Anyone that stops by this blog might already know about my interest in the science around this issue (see here and see here for example) and how quite a few more resources really should be directed into this 'sunshine' research area.

Research shows body image linked to overall life satisfaction

by Dr. Jekyll in Lunatic Laboratories

We're constantly bombarded by advertisements telling us we are too fat, too thin, not curvy enough, not flat enough -- or more often than not -- simply not enough. It shouldn't be a surprise to see that effect our day to day life, like it or not -- and it has. Researchers have just published results from a national study on the factors linked to satisfaction with appearance and weight.

Men who can tell a good story are seen as more attractive and higher status

by BPS Research Digest in BPS Research Digest

The results fit with evolutionary theoryStories can change how we think about the world, about the people they describe, and even ourselves. According to new research, they also influence our attitude to the storyteller. An article published in the journal Personal Relationships suggests that people portrayed as stronger storytellers are considered as higher status than those that aren’t – and this status can make them more romantically attractive, at least in the eyes of women.

What does a gluten-free diet do to the gut microbiome?

In answer to the question posed in the title of this post: "A GFD [gluten-free diet] changes the gut microbiome composition and alters the activity of microbial pathways."So said the findings reported by Marc Jan Bonder and colleagues [1] (open-access) who presented results based on the "changes in the gut microbiomes of 21 healthy volunteers who followed a GFD for four weeks."

Epigenetic study of lactose intolerance may shed light on the origin of mental illness

by Dr. Jekyll in Lunatic Laboratories

A new study on the epigenetics of lactose intolerance may provide an approach to understanding schizophrenia and other complex, serious illnesses. While that may seem odd, both lactose intolerance and schizophrenia are inherited. In addition, neither condition emerges in the first years of life, but rather both appear years or even decades later.

The Princess IS the Frog (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

By Hayley TrzinskiImage by Hayley TrzinskiThe Princess and the Frog is a very fun and imaginative children’s story… but not when pesticides are involved. Have you ever wondered how dangerous pesticides can be? Well, pesticides can harm more than just pests and weeds, and in the case of frogs, many pesticides and herbicides are causing problems. Atrazine, a chemical commonly used as an herbicide, can cause reproduction in male African clawed frogs to be impossible. In some cases, atrazine i........ Read more »

Your face can get you killed… 

by Rita Handrich in The Jury Room

Here’s a sad study that tells us stereotypes are alive and well in American court systems. Let’s say you are unfortunate enough to be on trial for murder. According to this study, how wide your face is can be the difference between life and death if you are convicted–even if you are actually innocent. We’ve […]

Water, carbamazepine and mother-embryo transmission

Digital media may be changing how you think

by Dr. Jekyll in Lunatic Laboratories

Tablet and laptop users beware. Using digital platforms such as tablets and laptops for reading may make you more inclined to focus on concrete details rather than interpreting information more abstractly, according to a new study. The findings serve as another wake-up call to how digital media may be affecting our likelihood of using abstract thought.

The darker side to swimming with dolphins?

Literally "knowing by heart": Signals from heart to brain prompt feelings of familiarity

by BPS Research Digest in BPS Research Digest

The idea that the body affects the mind is not new. The eminent American psychologist William James famously proposed that it is actually the physical sensation of fear that causes us to feel afraid. In more recent years, researchers have extended this principle, exploring the possibility that physical sensations play an important role in moral decisions and other processes usually seen as more purely cognitive or cerebral, such as memory.It's already known that physical markers of arousal such ........

I had previously covered their report on this blog (see here) and the suggestion that: "Somali (1 in 32) and White (1 in 36) children were about equally likely to be identified with ASD [autism spectrum disorder], but more likely to be identified with ASD than Black and ........
