Only Science Can Save Us, but Science Alone Can’t Save Us

by Paul Statt in Paul Statt Communications

Chris Mooney, writing about the recently un-raptured believers, climate change skeptics, and Moms who refuse to vaccinate, in Mother Jones (“Rapture Ready: The Science of Self Delusion,” May/June 2011) comes to the melancholy conclusion that science has proven that science seldom changes anyone’s mind....

Blood Test to Predict Breast Cancer in Advance

by United Academics in United Academics

Five years from now it may be possible to prevent breast cancer by taking a simple blood test. New research shows that the chances of developing the disease are linked to a molecular modification of the gene ATM, present on white blood cells. In the future, doctors may identify women with this molecular modification to prevent breast cancer occurrence.... Read more »

Psilocybin and personality

by Scott McGreal in Eye on Psych

Recent psilocybin research has found that not only does personality influence response to the drug, but that the drug can produce long-term changes in features of personality relating to openness to experience. The relationship between personality and psilocybin seems to be two-way. Future research may illuminate the shared basis of mystical-type experiences and related features of personality....

3 surprising insights on how food cravings relate to other desires in everyday life

by Ellen van Kleef in Food Intake Control

What is harder to resist? Checking your Twitter or Facebook account at work or eating a delicious, but fattening snack when you try to watch your calories? Both are inner conflicts, best described as 'I really want to do this, but I should not'.

This blog post looks at the paper of Wilhelm Hofmann, Kathlees Vohs and Roy Baummeister who recently tried to answer these questions in their Everyday Temptation Study. ... Read more »

More evidence that antibiotics are over-prescribed - How should that change?

by Rogue Medic in Rogue Medic

Today Lancet Infectious Diseases posted an early release of an article that shows that the antibiotic amoxicillin still does not work on viruses.

Many doctors still routinely prescribe antibiotics for viral infections.

Bias, perhaps the biggest confounder in medical research, is controlled for very well.

Understanding PREDIMED and the Mediterranean diet: heart-healthy or hype?

by Kismet in Biogerontology and Health

I am going to discuss the failings of the PREDIMED study, real and imagined. I will do this in a Question & Answer style. Several questions are inspired by theheart.org and NEJM comments and even statements by the low fat "gurus", Essselstyn, Ornish, McDougall or Pritikin. It is no surprise they are up in arms after the study has been published. It threatens their livelihood.... Read more »

Caries

by JB in Bone Broke

One of the little known benefits of studying ancient human teeth is that during my weeks or months of analyzing skeletal remains, I suddenly become EXTREMELY CONCERNED about my own dental health. Brushing twice daily, flossing, gargling with mouth wash, you name it – for the entire duration of data collection, I am a dentist’s dream. Once I’m out of the field these tactics drop off precipitously, and my abiding love of Coke Zero, or anything containing sugar quickly works to ba........ Read more »
