The Dollars and Cents of Eating Disorders

by Andrea in Science of Eating Disorders

I must admit that I cringe slightly every time I try to think about healthcare from an economics perspective. To me, this comes a little close to putting a dollar value on human beings, which feels uncomfortably post-humanistic to me. Nonetheless, there is no ignoring the ways in which economic concerns factor into policy decisions that drive our human services, including health care.
There are also a number of pragmatic reasons for thinking about the costs associated with illnesses; talki........ Read more »

Finally, a better Battery!

by Gabriel in Lunatic Laboratories

You know what technology hasn’t been able to keep pace with us? Well besides whatever tech the DMV uses, it’s batteries. Think about it, they are nasty, make a mess, are hazzardous, hard to recycle and weigh a freaking ton compared to the energy stored. Current battery technology is my number one problem with electric cars as it stands now. Between the weight, the resources, and the waste, electric cars are almost a wash. Not quite mind you, but almost.... Read more »

Does the wire matter?

by Kevin OBrien in Kevin OBrien's Orthodontic Blog

Does the wire matter? This blog is about wire. I thought that I should illustrate it with an orthodontic wire sculpture from the University of Washington. Each year the residents hold a competition on who can construct the best sculpture and this was the winner several years ago. When I wrote last weeks blog, I […]

Increased rates of suicidal ideation in adults with Asperger syndrome

by Paul Whiteley in Questioning Answers

"Our findings lend support to anecdotal reports of increased rates of suicidal ideation in adults with Asperger's syndrome, and depression as an important potential risk factor for suicidality in adults with this condition".Sunrise @ Wikipedia That was the very stark conclusion reached by the study by Sarah Cassidy and colleagues [1] (open-access) looking at self-reported rates of suicide ideation and suicide plans/attempts in a sample of adults newly diagnosed with Asperger syndr........

How can we increase altruism towards future generations?

by Christian Jarrett in BPS Research Digest

By guest blogger Dan JonesLike many parents, I often wonder what kind of world my two-year-old son will grow up to inhabit. Will the planet be ravaged by extreme climatic events, depleted of vital forests and biodiversity? Although some of our fears about the future may be overblown, if we don’t want to leave the planet in ruins for future generations, we need to think about how we act today — and maybe change our ways.Some changes are likely to involve minor sacrifices or small inconvenienc........

by Robb Hollis in Antisense Science

Animal testing is an incredibly controversial subject, with strong opinions on both sides. Whilst animal testing for cosmetics has now been banned in the EU, animals continue to be used in science, where they serve a vital role in biomedical research and drug development. Their importance is often overshadowed by the ethical issues surrounding the treatment of animals in research environments, and it’s important that people understand why and how they are used, as well as what measures ar........

Although I had other tips in the pipeline, I’m bumping this one up because it is time sensitive.

  The use of brain images is often criticized. A recent article by M Farah looks at what ‘the kernals of truth’ behind the critiques are and how safe we are to trust the images. (citation below). She is concerned by the confusion of legitimate worries about imaging and false ones. The first criticism that […]... Read more »

They Can See The Blood Running Through You

by Mark Lasbury in As Many Exceptions As Rules

Vampire bats sense heat via pit organs in their nose-leaves, but they find their victims by sight, smell and echolocation. New research shows that an alternatively spliced version of the capsaicin receptor TRPV1 is responsible for the heat sensing, but what do they use it for? Their teeth are so short that they must find blood vessels close to the surface – shallow vessels give off more heat than do deep vessels or skin where there is no large vessel.

Vampire bats occasionally feed on ........ Read more »

Men who are ashamed of their bodies are more prone to sexual aggression against women - US study

by Christian Jarrett in BPS Research Digest

When men are aggressive towards women, their behaviour is often driven by the feeling that their masculinity has been threatened. Consider these previous findings: men told they'd performed poorly on a strength test gave more painful electric shocks to a woman who criticised them; and men whose masculine identity was threatened subsequently harassed a feminist woman by sending her pornographic photos.Now Kris Mescher and Laurie Rudman have shown that this link is particularly strong for men who ........

Silence ENO2! More epigenetics and autism

by Paul Whiteley in Questioning Answers

The paper by Yu Wang and colleagues [1] (open-access here) concluded that: "reduced ENO2 expression may be a biomarker for a subset of autistic children" following their genome-wide methylation study of autism. For those who've picked up the word 'methylation' in that first sentence, this is yet another sign that epigenetics - the science of changes to gene function not entailing structural genomic changes - is starting to impact on autism research.Silentio! @ Wikipedia Based on an ini........
