Global Warming Denial: What Does it Take? A Case Study of Climate Change Denialists

by Nick in How to Paint Your Panda

Despite the established scientific consensus on global climate change, a substantial number of people, specifically Americans, deny its effects or its taking place. Why does this form of denialism persist so feverishly? What can mitigate this gap between the scientific community and the public?... Read more »

Vegetable oil in the fight against gastric disease

by Gabriel in Lunatic Laboratories

The bacterium Helicobacter pylori is strongly associated with gastric ulcers and cancer. Unfortunately, treating the bacteria with antibiotics is difficult and with the increase in antibiotic resistance it can be a dangerous fight to take on. Given the high rate of ulcers and stomach cancers, the need for a better treatment is becoming more apparent. New research may bring hope (and of all things) in the form of vegetable oil.

Flavanols for brain health

by neurosci in Neuroscientifically Challenged

Some degree of memory decline as we get older is an inevitability that many of us dread. Over the years, countless potential treatments have emerged to mitigate the effects of age-related memory loss; some have been the result of legitimate research efforts, many more have not. Regardless of their origins, very few have stood the test of time.A recent addition to that list of potential memory-enhancing treatments is the intake of a class of compounds called flavanols. Flavanols are naturally-occ........ Read more »

NICE does increasing access to vitamin D supplements

by Paul Whiteley in Questioning Answers

If you happen to live in England or indeed other parts of the UK, you'll no doubt have heard about NICE - the National Institute for Health and Care Excellence - as the body charged with providing us with appropriate evidence-based guidance on all manner of treatments and technologies for all manner of different diagnoses and conditions. I've talked before on this blog about the NICE guidance in relation to the autism spectrum (see here for example).My name is Elisabeth Shaw, last survivor ........ Read more »

The Day After Thanksgiving

by Aurametrix team in Environmental health

Seasonal changes, holidays and shopping activities are among the environmental factors that can influence our health. What positive or negative effects can we expect on Black Friday and days right after? The Friday-after-Thanksgiving was coined "Black" by police officers because of the fact that the traffic on the day after Thanksgiving is usually heavy and crowds are large. And they were right. According to the National Highway Traffic Safety Administration & CDC, Thanksgiving is the most dang........ Read more »

Fat Talk Free Zone: What is the Impact of Fat Talk on Body Dissatisfaction?

by Andrea in Science of Eating Disorders


There has been a veritable explosion of “anti-fat talk” movements in the body image and eating disorder prevention realms over the past few years. Indeed, campaigns like the Tri-Delta Sorority Fat Talk Free week have become relatively well known. Events like the “Southern Smash,” where participants literally smash scales are other iterations of this social phenomenon encouraging a more positive conversation around bodies.
I am, of course, a fan of the idea that we shouldn’t put o........ Read more »

Packing on the Pounds: Let the Holiday Eating Season Begin

by Melissa Chernick in Science Storiented

Here in the U.S., yesterday was Thanksgiving. A time of family, thanks, and lots and lots of food. Be honest, how much did you eat yesterday? Me, I watched a lot of football while I ate appetizers followed by turkey with gravy, mashed potatoes, green bean casserole, cranberry sauce, and cake. Then I entered a food coma for a few hours. It was glorious.I typically approach a holiday with a journal article, but this time I am going to use the holiday as a jumping off point: Thanksgiving as the sta........ Read more »

New discovery sheds light on the forming brain

by Gabriel in Lunatic Laboratories

The cerebral cortex, which controls higher processes such as perception, thought and cognition, is the most complex structure in the mammalian central nervous system. Although much is known about the intricate structure of this brain region, the processes governing its formation remain uncertain. Research has now uncovered how feedback between cells, as well as molecular factors, helps shape cortical development during mouse embryogenesis.... Read more »

When you think about spirits, do you see ghosts?

by Tom Rees in Epiphenom

Humans are finely honed for spotting intentional agents in our environment. Meaning that if you hear a rustling, or see a branch move, you’re instantly on the alert in case it is another person (this effect is has a name: ‘hyperactive agency detection’). You can see why evolution would have favoured that. Better safe than [Read More...]

Measure Kidney Function Don’t Estimate It

by Cristy at Living Donor 101 in Living Donors Are People Too

  Because direct measurement of GFR is cumbersome, it is often estimated using serum creatinine clearance. Problem is, most folks must lose more than 50% of their kidney function before the SCr measures above normal. The goal, of course, of eGFR is to produce results as close to mGFR as possible.   So – the …

Thanksgiving Special: Uncovering the link between sleep and food

by Bethany Christmann in Fly on the Wall

If you ate a big Thanksgiving dinner yesterday, you probably felt drowsy and sluggish afterward, a phenomenon often referred to as a “food coma”. The belief that it’s caused by the tryptophan in turkey is a long busted myth, and in fact it can happen after any carb-heavy meal. The reasons for this post-food slump […]... Read more »

A shocking result - people are more willing to hurt themselves than others for profit

by BPS Research Digest in BPS Research Digest

You wait in a cubicle, electrodes strapped to your body. In a room nearby, a stranger is confronted with a series of decisions. They can choose a smaller cash reward and avoid an electric shock, or a larger sum that comes together with an unpleasant zap. The twist is that in half of the trials, the stranger knows the associated shock punishment is for them, but in the others they know it’s you who will suffer. You glance nervously at the electrodes.It's a tough spot. Surely you will receive ma........ Read more »

The Autism-Spectrum Quotient: overlap between Asperger syndrome and schizophrenia

by Paul Whiteley in Questioning Answers

The paper by Tove Lugnegård and colleagues [1], including mention of one Maria Unenge Hallerbäck who has appeared on this blog previously, is fodder for today's discussions and their finding that a: "significant overlap of AQ [Autism-Spectrum Quotient] scores across the two diagnostic groups clearly reduces the discriminating power of the AQ in the separation of schizophrenia from AS [Asperger syndrome]."They say you're judged by the strength of your enemies.As per that link to ........

Fragile X and a new autism treatment

by Gabriel in Lunatic Laboratories

There are many roads to autism, none of them involve vaccination. I get tired of saying that, but it’s simple science, vaccines do not cause autism. Thankfully science knows this and is looking at not only what actually causes autism (Since again there are many different ways to develop on the spectrum). Well they may have found a new treatment for people affected by a common inherited form of autism by using a drug that is being tested as a treatment for cancer.... Read more »

Potential New Roles for Bacteria and B Cells in Promoting the Stomach Flu

by Geoffrey Hannigan in Prophage

We are all unfortunately familiar with the notorious stomach flu. Most of us have experienced that awful nausea, vomiting, diarrhea, and tiredness associated with catching some stomach bug. While there are many viral causes of the stomach flu (also called gastroenteritis), one of the most common is the Norovirus. The Norovirus is a common and contagious virus that is currently the leading cause of viral gastroenteritis...... Read more »

Why sadness lasts longer than other emotions

by BPS Research Digest in BPS Research Digest

Staying positive can feel like an uphill battle. No wonder: when Philippe Verduyn and Saskia Lavrijsen asked over 200 high-school students (average age 17) to reminisce about the duration of their recent emotional experiences, they found that sadness had an unfortunate habit of lingering, more so than any of the other 26 emotions studied, including joy, pride and relief.Indeed, the average duration of the episodes of sadness recalled by the students was 120 hours. At the other extreme, the most ........ Read more »
