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 mo........ 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...]

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 »

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 »

FC is a technique that has no validity

by Paul Whiteley in Questioning Answers

FC, by the way, refers to Facilitated Communication, a controversial technique which as the name suggests relies on a facilitator to support "the hand or arm of a communicatively impaired individual while using a keyboard or other devices with the aim of helping the individual to point and thereby to communicate." The quote for the title of this post comes from the paper by Ralf Schlosser and colleagues [1] who following systematic review, found "unequivocal evidence for facilitator co........ Read more »

Need to turn off the pain? Well now we can!

by Gabriel in Lunatic Laboratories

My sister suffers from chronic pain issues. I’ve written several posts about how her autoimmune disease is a special brand of pain that you will thankfully (almost certainly) never have to feel. While great strides have been made in pain management, there are still relatively few options that do not carry the risk of being extremely addictive. Well thankfully there is some new research and it offers hope, not just for my sister, but for the millions of people suffering from chronic pain that ........ Read more »

Synesthesia can be learned

by Janet Kwasniak in Neuro-patch

Synesthesia is a condition where one stimulus (like a letter) automatically is experienced with another attribute (like a colour) that is not actually present. About 4% of people have some form of this sensory mixing. It has been generally assumed that synesthesia is inherited because it runs in families. But it has been clear that […]... Read more »

Chikungunya Virus nsP2 and the ER stress response

by thelonevirologist in Virology Tidbits

Chikungunya virus (CHIKV) is the causative agent of an arthropod (mosquito) transmitted disease which is characterised by a high fever, rash, joint pain, and arthritis which was reported in 1952 in Tanzania but has spread since to Europe, Asia, Oceania and more recently to America, including the Caribbean and North America.
Here the inhibition of the ER stress response by the viral nsP2 protein is discussed in the context of viral infection. ... Read more »

Treatment Resistance in Eating Disorders

by William Yates, M.D. in Brain Posts

Clinicians treating patients with eating disorders find the challenge great with many treatment-resistant cases.To some extent, this is true of any clinical disorder. Outpatient treatment rolls and inpatient samples are over-represented by those failing to respond to initial interventions.A medical example is helpful here. Endocrinologists specializing in diabetes see more complicated cases where glucose control is difficult and diabetic complications are common.Diabetics with easy glucose contr........ Read more »
