Siblings, genetics and the autisms (plural)

by Paul Whiteley in Questioning Answers

The paper by Ryan Yuen and colleagues [1] suggesting that most siblings with autism do not share the same genetic variations thought to contribute to the condition has garnered quite a few media headlines of late (see here and see here).Applying the concept of whole-genome sequencing whereby the complete genetic blueprint of a person is mapped to provide "the most comprehensive collection of an individual's genetic variation" [2], 340 genomes from 85 families with two children with a d........

Why are American Atheists Disagreeable and Unconscientious?

by Tom Rees in Epiphenom

There’s a popular model of personality that splits it into five components: openness to experience, conscientiousness, extroversion, agreeableness, and neuroticism. And it’s well known that, while atheists tend to score high on openness, they tend to get low scores on conscientiousness and agreeableness. Back in 2010, Vincent Saroglou and colleagues assembled data from all the [Read More...]... Read more »

High-Dose Statin May Protect Heart Surgery Patients’ Kidney Health

by Wiley Asia Blog in Wiley Asia Blog - Health Sciences

Acute kidney injury often arises after major surgery because the kidneys can be deprived of normal blood flow during the procedure. The use of contrast media, or dyes, can contribute to this problem. In patients undergoing coronary angiography or percutaneous coronary intervention, which are heart procedures that use dyes to help surgeons visualize the arteries, a high dose of the statin atorvastatin was linked with a reduction in blood levels of creatinine, a marker of kidney injury, as well as........

You can’t unboil an egg? Well… now you can

by Dr. Jekyll in Lunatic Laboratories

There is a saying, “you can’t unboil an egg.” Usually this is just illustrating cause and effect; you can’t turn back time, or what’s done is done. Well now scientists have successfully unboiled an egg, so suck it thermodynamics. An international team of chemists have accomplished this feat – an innovation that could dramatically reduce costs for cancer treatments, food production and other segments of the $160 billion global biotechnology industry, according to the findings....

More Complexity = More Disruptions?

by Andreas Wieland in Supply Chain Management Research

Trends in management towards a concentration on core competencies and outsourcing of non-core activities have created complex networks, i.e., global supply chains. At the same time, it has been discussed that this increased complexity has also made companies more vulnerable. An interesting paper, Structural Drivers of Upstream Supply Chain Complexity and the Frequency of Supply […]... Read more »

The secret for a longer life? Kill your unfit cells

by Isabel Torres in Science in the clouds

If you had the choice, would you like to live until you’re 130 years old? New research in fruit flies shows that manipulating a single gene can extend their lifespan up to 60%, suggesting that living well into your hundreds might become a reality in the foreseeable future.Dying of old age is a strange thing. Why does our health decline just because we’re old? Although the answer might at first seem obvious or simple, it really isn’t. There are countless theories of ageing, a few popular ev........

The Bed Bug’s Piercing Penis (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

By Rachael Pahl Sex is a dangerous, but necessary, part of life. Across the animal kingdom, there are a multitude of things that can go wrong. You could be injured in a fight by someone who wants to steal your mate, or maybe your partner eats you because you’re taking too long. Either way, nature must have a pretty good reason for the traumatizing effects of sex. A male bed bug traumatically inseminates a female.

His brain made him do it” and so I feel much less empathy for him 

by Rita Handrich in The Jury Room

We’ve written about the brain based defenses a lot here. And here’s an article that may shed light on how the presentation of neural defenses could backfire on defense attorneys. First, let’s look at the research. The researchers wondered how the biological explanation of mental illness might affect the empathy of mental health clinicians toward […]

We're more likely to cheat when we're anxious

by BPS Research Digest in BPS Research Digest

When we’re stressed out and feeling threatened, our priority becomes self-preservation. According to new research, this defensive mode even affects our morality, making us more likely to cheat and excuse our own unethical behaviour.Maryam Kouchaki and Sreedhari Desai demonstrated this through six experiments. In the clearest example, 63 student participants spent three minutes listening to either calm music, or in the anxiety condition, to Bernard Herrmann's Psycho score. Those freaked out by ........

Is it necessary to use brain imaging to understand teen girls' sexual decision making?

by The Neurocritic in The Neurocritic

“It is feasible to recruit and retain a cohort of female participants to perform a functional magnetic resonance imaging [fMRI] task focused on making decisions about sex, on the basis of varying levels of hypothetical sexual risk, and to complete longitudinal prospective diaries following this task. Preliminary evidence suggests that risk level differentially impacts brain activity related to sexual decision making in these women [i.e., girls aged 14-15 yrs], which may be related to pas........

What factors are linked to behavioural crises in autism?

by Paul Whiteley in Questioning Answers

The question posed in the title of this post was asked and [partly] answered by the paper by Vincent Guinchat and colleagues [1] based on the analysis of 58 adolescents diagnosed with an autism spectrum disorder (ASD) and "hospitalized for severe challenging behaviors." Challenging behaviours, by the way, refers to a whole spectrum of presentations which doesn't just include aggressive or violent behaviours (see here). Indeed, I recently talked about irritability and autism (see here), whic........ Read more »

Transferring primary symbionts: a missed link?

by Mauro Mandrioli in The aphid room

One of the most studied example of symbiotic interaction is related to aphids and their symbiont Buchnera aphidicola  that they host in specialized cells called bacteriocytes. Each aphid may host about 6 millions of Buchnera cells that are involved in the continuous overproduction of tryptophan and other amino acids. In addition to obligate symbionts, exemplified […]...

The unsolved mysteries of protein misfolding in common neurodegenerative diseases

by neurosci in Neuroscientifically Challenged

Throughout the 1970s, biochemist Stanley Prusiner was obsessed with trying to find the causative agent for a mysterious group of diseases. The diseases, which included kuru and Creutzfeldt–Jakob disease in humans and scrapie in sheep, were characterized by slowly-developing symptoms and neurodegeneration so severe it eventually caused the brain to take on the appearance of a sponge (due to myriad little holes that developed where grey matter was lost). By the time Prusiner began studying these........ Read more »

Whose Culture is it Anyway? Disentangling Culture and Eating Disorders - Part 3

by Andrea in Science of Eating Disorders

The articles I’ve looked at so far in this series (Becker, in part 1, and Keel and Klump in part 2) give us some insight into the idea that the link between “Western” societies and eating disorders is more complex than a simple matter of media exposure. But, having read these studies, I was still left a bit wanting in terms of unpacking that black box of “culture” that gets tossed around in scholarly and popular literature. What, exactly, are we talking about when w........ Read more »

Lucid dreaming: The similarities between dreaming and wakefulness

by Dr. Jekyll in Lunatic Laboratories

To control one’s dreams and to live out there what is impossible in real life — a truly tempting idea. Some people — so-called lucid dreamers — can do this. Researchers have discovered that the brain area which enables self-reflection is larger in lucid dreamers. Thus, lucid dreamers are possibly also more self-reflecting when they are awake....

Hartnup disease in coeliac disease: lessons for 'some' autism?
