World Food Day - Food Security through the Lens of Nutrition

by Wiley Asia Blog in Wiley Asia Blog - Life Sciences

The Foresight report has described an unprecedented confluence of pressures whereby a growing, and in some cases, increasingly prosperous global population, alongside increasing demand for limited resources and the pressing need to address environmental challenges, including climate change and changing weather patterns, means that food security is seriously and increasingly threatened. Much of the discussion has focused on greenhouse gas emissions associated with food production and the contribu........ Read more »

JUST PUBLISHED: Resilience and Responses to Persistent Pain

by Mark Rubin in The University of Newcastle's School of Psychology Newsline

The concept of resilience is of considerable interest in clinical practice.  The resilient person shows relatively speedy recovery from a disturbance and an ability to resume their former work practices, habits and normal life.  In addition, they are able to maintain that recovery over the long-term.The maintenance of recovery is of particular interest in patients suffering from chronic pain, since the presence of persistent pain leads to a raft of behavioural and cognitive changes all........

A Random Walk into the Genetics of Axon Guidance

by Wadsworth in Wadsworth Guidance

The man claimed he was a wizard and had cast the “spell of attraction” on the target.  Now the target would guide his arrow to the mark.  So we gave the man a broken arrow and watched to see if this arrow could hit the target.  The man took the arrow and flung it at the target.  Indeed, this arrow too could hit the target. Credit: Nina Matthews PhotographyPerhaps we had asked the wrong question.  Instead of looking at whether the arrow made it to the target........

You can tell [my mood] by the way I walk

by Gabriel in Lunatic Laboratories

Ever see a guy walking down the street and know he’s depressed? Or how about someone happy, with a little bounce in their step? The way we walk says a lot and by some estimates roughly 90% of what we are telling people isn’t coming out our mouth, it’s all body language. Our walk says a lot about the kind of mood we are in, but in the question of what came first our mood or our walk, researchers have now shown that it works both ways.... Read more »

My Dog Comes First: The Importance of Pets to Homeless Youth

by CAPB in Companion Animal Psychology Blog

Dogs and cats have both advantages and disadvantages for street-involved youth.Photo: everst / ShutterstockResearch by Michelle Lem et al (University of Guelph) asks homeless young people (aged 18-24) what their pet means to them. Previous studies have focussed on the benefits to homeless people of owning a dog or cat. The aim of this study was to get a balanced picture of both the advantages and disadvantages. Ten homeless young people took part in in-depth interviews about their pet. 8 of........ Read more »

Marburg Virus and Keap1: induction of antioxidant response whilst inhibiting selective autophagy ?

by thelonevirologist in Virology Tidbits

Under normal conditions, Keap1 interacts with Nrf2 via the Nrf2-ECH homology domain 2 (Neh2) located within the N-terminal end of Nrf2 and ubiquitinates Nrf2 in a Cullin-3 dependent manner., leading to the proteasomal degradation of Nrf2 via the 26S proteasome independent of autophagy. Inactivation of Keap1 by binding p62/SQSTM1 via the C-terminal KELCH domain of Keap1 and the Keap1 interacting domain (KIR) of p62/SQSTM1 induces the degradation of Keap1 via selective autophagy, thus releasing Nr........

Trauma research needs to be more global and accessible

by Eva Alisic in Trauma Recovery

Imagine a 7-year old boy living in India. One day, his father gets drunk and kills his mother. The boy is a witness to the homicide, and develops a high fever as a response. Imagine you’re the mental health professional who is called to support the boy. Some of the things you would want to know are how children in India respond to severe trauma, what words they use, and what helps them to recover.

Unfortunately, that information is virtually nonexistent. T... Read more »

Remembering visual images

by Janet Kwasniak in Neuro-patch

There is an interesting recent paper (see citation) on visual memory.

In this […]... Read more »

Frankenstein Meets Genetic Modification

by Mark Lasbury in As Many Exceptions As Rules

Halloween conjures up monsters, like Mary Shelly’s Frankenstein. Her story is just as applicable for us today – the story of science being responsible for what it creates. The so-called Frankenfoods are called dangerous – but why? Studies that label them dangerous have been retracted or are merely correlative. New studies have shown that genetically modified crops are safe for livestock and humans. However, there are valid concerns, so every GMO must be tested rigorously.... Read more »

Hookworm infection and microchallenge for coeliac disease?

by Paul Whiteley in Questioning Answers

I'm getting rather baffled by some of the literature appearing with the autoimmune condition coeliac (celiac) disease in mind. The paper by Kalliokoski and colleagues [1] started the bafflement ball rolling with their suggestion that: "administration of IgA-deficient celiac disease patient serum or total IgG induces both deterioration of the intestinal mucosa and clinical features of celiac disease in mice". Then came the paper from Namatovu and colleagues [2] who concluded that: ........ Read more »

How You Feel About People is Related to How You Feel About Cities

by Mark Rubin in Mark Rubin's Social Psychology Research Blog

There are numerous structural factors that influence people’s attitudes towards cities. However, these factors may be constituents of broader sociocultural “questions” that people ask about their cities.  For example, residents’ concern about the transport and entertainment venues of a city might form part of a broader social psychological concern about the potential for the city to accommodate their need to meet friends and socialize with others. Alternatively, people might focus on a ........ Read more »

Harry Potter and the Prisoner of Mid-Cingulate Cortex

by The Neurocritic in The Neurocritic

What happens in the brain during a highly immersive reading experience? According to the fiction feeling hypothesis (Jacobs, 2014), narratives with highly emotional content cause a deeper sense of immersion by engaging the affective empathy network to a greater extent than neutral narratives. Emotional empathy – in this case, the ability to identify with a fictional character via grounded metarepresentations of ‘global emotional moments’ (Hsu et al., 2014) – relies on  a number of b........

What is the habenula?

by neurosci in Neuroscientifically Challenged

Despite the fact that it is present in almost all vertebrate species, very little was known about the habenula until fairly recently. In the past several years, however, the habenula has received a significant amount of attention for its potential role in both cognition (e.g. reward processing) and disorders like depression. Still, the habenula remains a little-known structure whose functions are yet to be fully elucidated.Where is the habenula?The habenula is part of the diencephalon and, toget........ Read more »

Carbon’s Place in a Silicon World

by Gabriel in Lunatic Laboratories

Everything is silicon based, well mainly your computer, your TV, your ipad, and pretty much every piece of electronics in existence. Still the world turns and so does technology; at a similarly fast pace no less. Even as the 2014 Nobel Prize in Physics has enshrined light emitting diodes (LEDs) as the single most significant and disruptive energy-efficient lighting solution of today, scientists around the world continue unabated to search for the even-better-bulbs of tomorrow. In this search we ........ Read more »
