Video protects girls from the negative effects of looking at ultra-thin models

by BPS Research Digest in BPS Research Digest

'No wonder our perception of beauty is distorted' - that's the concluding catchphrase of a one-minute video called 'evolution' made by Dove a few years ago to show how cosmetics and computer trickery are used to create the unrealistic portrayals of female models on advertising billboards. Now a team of researchers at the University of the West of England, led by Emma Halliwell, have tested whether viewing this short video can buffer young girls against the negative effects of looking at images o........

Friday Weird Science: Female Orgasm and Ejaculation. And, Or? Or both?

by Scicurious in Neurotic Physiology

Sci would like to note that the methods of this study are not for the faint of heart. I looked at them and got the feeling that I imagine guys get when people talk glibly of things like ballsack punching. Let’s just put it this way: electrode needles. IN YOUR CLITORIS. Now, please relax, and [...]... Read more »

The evolutionary ecology of the genome

by Graves in Down the Cellar

A new paper by Pierre Durand and Richard Michod suggests an interesting line of inquiry in the "post-genomic" era. Instead of focusing on the genome as a mere collection of genes, there is an opportunity to study the selective processes that result in both the origin and subsequent evolution of the genome. This is something we can approach with data now that the genomes of so many organisms are ... Read more »

Neury Thursday: A Neurobiological Model of the ADHD Paradox

by Allison in Dormivigilia

In this week's Journal of Neuroscience researchers have elucidated the neural mechanisms of why ADHD medications calms those with ADHD down and make those without ADHD hyper. Perhaps this is the crude, yet slightly unethical way to address the overdiagnosing of ADHD in America???... Read more »

…The Forest and the Trees

by Rift in Psycasm

Recently I had to float an idea to my girlfriend that I knew she would not be receptive to. In the next few weeks I have to deliver news to the Assassins’ League about some impending changes. I know some individuals won’t care, some might be excited, and some will definitely object. I need to [...]... Read more »

Anoxia Tolerance and Species Longevity

by Reason in Fight Aging!

I noticed a paper on longevity in turtles today that speculates on a link between species life span and tolerance of low-oxygen environments. It seems to be as interesting a line of research as any opened up by the comparison of differences in biochemistry and longevity between species. Why are long-lived species long-lived, and can we expect the answers to translate, as for calorie restriction research, into potential benefits for human health? Forever young: mechanisms of natural anoxia tolera........ Read more »

FDA Reports Critical Drug Shortages

by Dirk Hanson in Addiction Inbox


Delays put EMTs on alert for dextrose, naloxone, epinephrine.
It’s the kind of thing most people take for granted: You’re suddenly taken seriously ill—a heart attack, dehydration, asthma, shock, perhaps even a heroin overdose—and in the ambulance or the emergency room, medical professionals immediately go to work, using the right drugs and medications for the job.
Imagine lying in the back of an ambulance, in cardiac arrest, or experiencing an episode of acute schizophrenia, or turning........ Read more »

Cheers to a Decreased Risk of Arthritis

by Shaheen Lakhan in Brain Blogger

Preliminary findings presented at annual meeting of the European League Against Rheumatism suggest that drinking alcohol may reduce the risk of developing several types of arthritis. The results of this study need to be interpreted with caution, however, since no cause and effect relationship was confirmed. The case-control study evaluated the alcohol consumption habits of [...]... Read more »

Nemesis meets its, uh, nemesis

by Emma in we are all in the gutter

Interesting fact of the day: examining the fossil record suggests that mass extinctions on Earth occur approximately once every 26 million years (Myr). One possible explanation for this is a companion dwarf star to the Sun on a 26 Myr orbit. Every time is passes by, the theory goes, it messes up the Oort cloud [...]... Read more »

Young evangelicals are greener... but no more liberal

by Tom Rees in Epiphenom

During the last US presidential campaign, there was a flurry of excitement when pundits caught hold of the idea that some young Christian evangelicals might possibly vote for Obama (despite the fact that he is, apparently, a Muslim, or perhaps not even a Christian, or something). This would not be so surprising. After all, there is nothing set in stone about what the political and even moral beliefs of an evangelical should be. There would be nothing in principle to stand in the way of a bit of ........ Read more »

About Those Chaco Burials

by teofilo in Gambler's House

In discussing a recent paper using stable-isotope techniques to evaluate subsistence in the Southwest during the Basketmaker period, I mentioned that one of the control samples used for contextual comparisons of the Basketmaker results came from Chaco Canyon great house burials.  I don’t know how on earth the Utah-based researchers managed to get permission to [...]...

Ethics of Labeling

by Anastasia B in Biofortified

We’ve discussed labeling many times at Biofortified, usually looking at things from a practical perspective, such as in the posts What’s in a label? and Labeling GMOs. I argue that anything that is scientifically proven to be a hazard should be a mandatory label. For example, a label that a product contains nuts is justified by severe allergic reactions, even though the additional label may add to the cost of a product for people who don’t have Continue reading......

Scientists With Data Agree…A Deepwater Oil Plume Exists in the Gulf

BP want’s to deny the presence of a deepwater oil plume in the Gulf of Mexico.  The very oil plume both predicted by models published in 2003.  The very oil plume that the massive amounts of dispersant injected at depth created to prevent oil from washing ashore.  Even the government wants to deny the existence of any . . . → Read More: Scientists With Data Agree…A Deepwater Oil Plume Exists in the Gulf...

After 40 years of research, there may be a reason why Aplysia can learn

by Björn Brembs in bjoern.brembs.blog

I'm currently in sunny southern California for some experiments at UCSD. This is the place where one can find the marine snail Aplysia in its natural habitat. As I've been working with Aplysia for about ten years now, I felt it was about time to see Aplysia in the wild and observe what these animals do when they're not in a tank waiting to be experimented upon. Just this morning, before heading out to UCSD, I went snorkeling in La Jolla Cove in the hope of seeing some specimens........ Read more »
