We're more likely to cheat when we think it's our last chance to do so

by BPS Research Digest in BPS Research Digest

Imagine spending your school half-term week with a forgetful relative who always leaves money scattered around the house. Would you pinch any? If so, when, and why? A new paper suggests that we are most likely to “cheat at the end”, and uses a neat method to find out why.A number of theories predict we are likelier to cheat later than earlier. Perhaps we award ourselves moral credits for being good earlier, and later spend them like Catholic indulgences for guilt-free sin. Or maybe the strug........ Read more »

Blood & Fog: The Military's Germ Warfare Tests in San Francisco

by Rebecca Kreston in BODY HORRORS

The Nuremberg Code was drafted in 1947 following the appalling revelations of human experimentation committed in Nazi concentration camps. The overarching goal of the Code was to establish a set of rules for the ethical conduct of research using human subjects, guaranteeing that the rights and welfare of such participants would be protected. Two important principles guide and define this Code: the concept of voluntary, informed consent and that no experiment shall be conducted in which "there i........ Read more »

Pharma Make The Most of A Negative Result

by Neuroskeptic in Neuroskeptic_Discover

A misleading piece of statistical rhetoric has appeared in a paper about an experimental antidepressant treatment. The study is published in the Journal of Affective Disorders. JAD is a respectable mid-ranked psychiatry journal - yet on this occasion they seem to have dropped the ball badly.



The study examined whether the drug armodafinil (Nuvigil) improved mood in people with bipolar disorder who were in a depressive episode. In a double-blind trial, 462 patients were randomized to treat... Read more »

Rare neurons enable mental flexibility

by Dr. Jekyll in Lunatic Laboratories

Behavioral flexibility — the ability to change strategy when the rules change — is controlled by specific neurons in the brain, Researchers have confirmed. Cholinergic interneurons are rare — they make up just one to two percent of the neurons in the striatum, a key part of the brain involved with higher-level decision-making. Scientists have suspected they play a role in changing strategies, and researchers at OIST recently confirmed this with experiments.... Read more »

Cellular Senescence in Regeneration

by Max_Yun in the Node

Salamanders are remarkable organisms. Following the amputation or loss of complex structures such as parts of their eyes, hearts and brains, tails -including the spinal cord-, jaws and even full limbs, they are able to set up a regeneration programme which leads to the exact replacement of the missing structure, even as adults. As such, […]... Read more »

What personality features do heroes and psychopaths have in common?

by Scott McGreal in Eye on Psych

The search for a positive face of psychopathy prompted a study examining whether psychopaths and heroes share certain personality traits. Both psychopathy and heroism were correlated with a history of antisocial behavior, but the reasons for this remain unclear. Heroes might have more mature personalities than psychopaths, in spite of what features they may have in common. ... Read more »

Who Will Pay for All the New DBS Implants?

by The Neurocritic in The Neurocritic

Recently, Science and Nature had news features on big BRAIN funding for the development of deep brain stimulation technologies. The ultimate aim of this research is to treat and correct malfunctioning neural circuits in psychiatric and neurological disorders. Both pieces raised ethical issues, focused on device manufacturers and potential military applications, respectively.A different ethical concern, not mentioned in either article, is who will have access to these new devices, and who is goin........

Brain scan can predict who responds best to certain treatment for OCD

by Dr. Jekyll in Lunatic Laboratories

Tens of millions of Americans — an estimated 1 to 2 percent of the population — will suffer at some point in their lifetimes from obsessive-compulsive disorder, a disorder characterized by recurrent, intrusive, and disturbing thoughts (obsessions), and/or stereotyped recurrent behaviors (compulsions). Left untreated, OCD can be profoundly distressing to the patient and can adversely affect their ability to succeed in school, hold a job or function in society.... Read more »

Natural wilderness areas need buffer zones to protect from human development

by Dr. Jekyll in Lunatic Laboratories

Despite heavy development, the U.S. still has millions of acres of pristine wild lands. Coveted for their beauty, these wilderness areas draw innumerable outdoor enthusiasts eager for a taste of primitive nature. But University of Georgia researchers say these federally protected nature areas have a problem: Their boundaries have become prime real estate.... Read more »

Probiotics, schizophrenia and inflammation

A single mutation helped last year’s flu virus gain an advantage over the vaccine

by Dr. Jekyll in Lunatic Laboratories

The 2014-2015 flu vaccine didn’t work as well compared to previous years because the H3N2 virus recently acquired a mutation that concealed the infection from the immune system. A new study reveals the major viral mutation responsible for the mismatch between the vaccine strain and circulating strains. The research will help guide the selection of viral strains for future seasonal flu vaccines.... Read more »

Nervous Sea Squirts Squirt Out Their Stomachs and Grow New Ones

by Elizabeth Preston in Inkfish



We may call someone gutless who's acting afraid. But certain coral-reef dwellers take gutless to a whole other level: they shoot their digestive tracts out of their bodies when they feel threatened. This seems to deter nearby fish from taking a bite. Even more amazing, though, is how quickly the gutless animals grow back their organs.

Polycarpa mytiligera is a little tube-shaped creature called an ascidian, or sea squirt. It resides in tropical waters of the Indian and Pacific oceans. Wit... Read more »

Oak bump medicine

by Rosin Cerate in Rosin Cerate

I own a couple of neat old medical books. One was published in 1935 and is entitled The Canadian Formulary. It's essentially a cookbook for pharmacists, particularly ones who plied their trade at the military hospital in Kingston, Ontario (there's a stamp on the inside cover). The book contains some interesting recipes, to say the least, which is what you get when your ingredient list includes arsenic, lead, mercury, strychnine, and chloroform.One recipe in particular that recently caught my eye........

Is dyslexia associated with exceptional visual-spatial abilities?

by BPS Research Digest in BPS Research Digest

Image: Jose.Stuefer / FlickrChildren and adults with dyslexia have reading skills that are weak relative to their overall intelligence. That's why it is often referred to as "specific learning disability". But what if such a profile also tended to be associated with exceptional strengths in other areas, such as visual skills? That's certainly what some experts have proposed, for example based on the observation that people with dyslexia are over-represented in fields that involve visual-spatial ........ Read more »
