Profiling Risk: Predicting Alcoholism In Adolescents

by Agnese Mariotti in United Academics

It appears that certain personality traits and traumatic early life events are typically associated with binge drinking in teenage years. However, the predictive power of each type of factors by itself (personality or individual history for example) is not absolute. A new study evaluated not only one single factor, but a series of psychological, genetic, and neurological elements for their ability to determine, when combined, current and future alcohol misuse in a large group of youngsters. ...

How your mood changes your personality

by Christian Jarrett in BPS Research Digest

Participants scored higher on neuroticism & lower on extraversion when they were sadExcept in extreme cases of illness or trauma, we usually expect each other's personalities to remain stable through life. Indeed, central to the definition of personality is that it describes pervasive tendencies in a person's behaviour and ways of relating to the world. However, a new study highlights the reality - your personality is swayed by your current mood, especially when you're feeling down.Jan Quere........ Read more »

Blood lead levels and childhood behaviour

by Paul Whiteley in Questioning Answers

"Blood lead concentrations, even at a mean concentration of 6.4 µg/dL, were associated with increased risk of behavioral problems in Chinese preschool children, including internalizing and pervasive developmental problems". That was the conclusion of the study by Jianghong Liu and colleagues [1] looking at blood lead levels in preschoolers aged 3-5 years resident in Jiangsu province in China. Some associated media accompanying this study can be viewed here including the text: "This re........ Read more »

Know your brain: Thalamus

by neurosci in Neuroscientifically Challenged

Where is it?











Thalamus (in red).






The thalamus is a large, symmetrical (meaning there is one in each hemisphere) structure that makes up most of the mass of the diencephalon. A large number of pathways travel through the thalamus, including all of the sensory pathways other than those devoted to olfaction (smell).What is it and what does it do?The thalamus is often described as a relay station. This is because almost all sensory informati........ Read more »

Coronavirus nsp, ER stress, UPR, and ERAD

by thelonevirologist in Virology Tidbits

The essential step in the intracellular life cycle of many positive strand ssRNA viruses is the generation of double membrane vesicles (DMVs) that in most cases (but not all) contain the viral replication and transcription complexes (RTC) and hence serve as the replication platform. In the case of both the Nidovirales and the Flaviviridae these are formed by subverting the membrane of the ER in the absence of conventional ER and secretory pathway markers. Additionally, non-structural proteins (........ Read more »

What does it feel like to be depressed?

by Christian Jarrett in BPS Research Digest

We're used to reading about depression as a checklist of symptoms. These lists have their uses, but arguably they miss the human story of what depression truly feels like. Now the psychologists Jonathan Smith and John Rhodes have published their analysis of the first-hand accounts of seven therapy clients, (three women and four men) about what it's like to be depressed for the first time. The participants had an average age of 44, and all had been referred for therapy in London.The first theme t........ Read more »

Video Tip of the Week: VectorBase, for invertebrate vectors of human pathogens

I wish I had been clever enough to coordinate this week’s Video Tip of the Week with “Mosquito Week” a couple of months back.

The mosquito was deemed: The […]... Read more »

Do Puppy Tests Predict Adult Dog Behaviour?

A new study follows dogs from neonates to adults to find out if puppy tests predict adult behaviour.Photo: Mikkel Bigandt / ShutterstockLots of people want to know if a puppy’s behaviour will tell you what it will be like as an adult dog.

East To West And Back Again

by Mark Lasbury in As Many Exceptions As Rules

Sunflowers were named by Linnaeus for their round shape and bright color that reminded him of the sun, not because they follow the sun. But they do seem to turn to face the sun each day. A new review has looked at the molecular mechanisms that control the movement of the apex of the plant. But questions remain – how does the plant turn back to the east at night? Why is it that the flower turns but the leaves do not? Why does the movement stop when the flower matures?... Read more »

The Workplace Ostracism Scale: Making the subjective objective?

by Doug Keene in The Jury Room

It’s always tough to measure something that seems very subjective. Like ostracism. Are you being ostracized (excluded, left out, or shunned) or are you just way too sensitive? Intrepid researchers have pushed forward though and brought us the Workplace Ostracism Scale. Ostracism is very much like incivility which is seen as very hard to objectively […]

Organic acids as biomarkers of autism?

by Paul Whiteley in Questioning Answers

Whilst I am always a little cautious about the use of the word 'biomarker' when applied to a heterogeneous condition like autism, even the autisms, I am nevertheless always intrigued at any reasonable prospect reported in the scientific literature. So it was when I read the paper by Joanna Kałużna-Czaplińska and colleagues [1] and their assertion that "there is a significant metabolic difference between autistic and non-autistic children" and onwards that "21 metabolites were identified ........
