A probiotic E. coli from the trenches of World War I

by Rosin Cerate in Rosin Cerate

Escherichia coli is a two-faced little slimeball.As is often the case with bacteria, it comes in many varieties. Some, such as the infamous O157:H7 serotype, can make people very ill. Once inside us (usually via contaminated food or water), they do harmful things like pump out toxins and feast upon the walls of our intestines. We're talking lots of bloody diarrhea.Yet other strains of E. coli have done us a lot of good. For decades now, research laboratories have been using strain K12 and i........ Read more »

Help me, neighbor!

by ragothamanyennamalli in Getting to know Structural Bioinformatics

We all have neighbors who help us in our hour of need. Some go out of the way as well. In enzymes too, it seems, that neighbors play a crucial role. Lafond et al in their recent publication in the Journal of Biological Chemistry report the invovlement of neighboring chains of the same enzyme, lichenase. Apart from the role of stabilizing the quarternary structure (a trimer), they are also invovled in the enzymatic activity.... Read more »

There are at least 216 foreign words for positive emotional states and concepts that we don't have in English

by BPS Research Digest in BPS Research Digest

One criticism levelled at positive psychology is that it takes an overly Western-centric view of the lighter side of human experience. Addressing that problem, Tim Lomas at the University of East London has begun a deep investigation into all the non-English words for positive emotions and concepts that don't have a direct translation in English.Publishing his initial findings in the The Journal of Positive Psychology, Lomas' hope is not only that we might learn more about the positive psyc........

Holding Back: Inhibition

by Joshua Fisher in Text Savvy

I remember years ago being required to write math problems containing unnecessary information so that students would have to choose the information that they needed. But just making kids do something is not the same thing as teaching them something. It is, rather, a total cave to assessment obsession—we just found a way to call assessment "instruction"....

Religion linked to reduced levels of stress hormones in young American Blacks

by Tom Rees in Epiphenom

Compared with Whites, Black Americans have  high levels of an important stress hormone called cortisol circulating in their bloodstream. No-one really knows why this is, but the differences remain even after you take into account social and psychological factors. It seems likely that simply being black exposes you to a cumulative effect of increased lifetime [Read More...]... Read more »

The music of the mind: throwing light on human consciousness

by Dr. Jekyll in Lunatic Laboratories

UNSW Australia scientists have shown that complex human brain activity is governed by the same simple universal rule of nature that can explain other phenomena such as the beautiful sound of a finely crafted violin or the spots on a leopard. The UNSW team has identified a link between the distinctive patterns of brain function that occur at rest and the physical structure of people's brains.

Shelter Dogs Live Up To Expectations (Mostly)

by CAPB in Companion Animal Psychology Blog

Testing behaviour in the shelter is tricky, but most people who adopt a dog would do so again. Animal shelters often assess the behaviour of dogs before rehoming them, but because the tests are not always scientifically validated, Mornement et al (2014) developed the B.A.R.K. protocol. Results of the B.A.R.K. on 74 shelter dogs successfully predicted in-home ratings for fear and friendliness after the dogs had been adopted, but not anxiety, activity level or compliance. A follow-up paper by........ Read more »

Simple Jury Persuasion: Why do people fall for what seems profound but is really nonsensical? 

by Rita Handrich in The Jury Room

We think these authors are trying to be amusing but they are very, very serious about their work and have even attracted the attention of someone they target in their article (Deepak Chopra). Essentially the authors focus on who falls prey to “profound pseudo-bullshit” and why. And that, is an important thing for us to […]

Men who stick up for women's rights are subjected to more sexual harassment at work

by BPS Research Digest in BPS Research Digest

Upon mention of sexual harassment at work, it's natural to think immediately of women as the targets, but actually men experience harassment too. And it's on the increase, at least in the US. In 2013, men filed 17.6 per cent of the thousands of sexual harassment charges recorded in the country that year (up from 16.1 per cent in 2011).A new study in Psychology of Men and Masculinity surveyed 326 men in the US (most were white, 25 were gay or bisexual) about their experiences of sexual harassment........
