Mindfulness and exercise?

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

Now I know this might seem a strange heading when we think of mindfulness practice normally, but this isn’t ‘treatment as usual’. The definition of mindfulness in this study is ‘The body scan practice involves systematically moving awareness through each part of the body and noticing the presence of sensation in a detailed and precise … Read more...

Hey maybe scientists should do more than just wait for their journal to issue a press release on their new fabu article

by Christina Pikas in Christina's LIS Rant

The authors thesis is that the only mandatory communication of results is in peer reviewed journal articles. Scientists aren't required to do other communicating and often leave communication to the public to the media. They ask if is this is adequate given the very low percentage of scientific articles that ever make it into the press, particularly in areas outside of health and medicine, and also given the fact that for everyone out of formal education, the media is their primary source of sci........

What Makes Humans Unique? (I): The Evolution of the Human Brain

by Michael in A Replicated Typo 2.0

Hello! This is my first post here at Replicated Typo and I thought I’d start with reposting a slightly modified version of a three-part series on the evolution of the human mind that I did last year over at my blog Shared Symbolic Storage.
So in this and my next posts I will have a look at how human cognition evolved from the perspective of cognitive science, especially ‘evolutionary linguistics,’ comparative psychology and developmental psychology.
In this post I’ll focus on the evolu........ Read more »

Small no-take zones can help top predators

by Joel Rein in Moth Eyes

It’s difficult to protect large marine areas from fishing – a great deal of resources must be put into patrolling and enforcing such an area. However, new research suggests that small but well-targetted protection zones can have a significant effect all the way up the food chain.

African Penguins (Spheniscus demersus) are a vulnerable species of [...]... Read more »

The Art and Science of Triggering

by Vahid Motlagh in Ideas for a deeper sense of life

Building a theory for triggers is a pet project I am working on it in my free time. Although I have not developed it much further since January 2009 you can read an introduction to it in a previous post here on this blog which also includes a version of the theory's associated mind map.Based on the above mentioned general purpose mind map I can suggest some solutions for encouraging a major change or action about the current pressing issues of global climate change, that is the need to mitigatio........

Antigen presentation in the bloodstream: How invariant NKT cells are activated by Lyme disease spirochetes

by Microbe Fan in Spirochetes Unwound

The spirochete Borrelia burgdorferi is the tick-borne agent of Lyme disease, which affects the joints, nervous system, and heart.  After being deposited into the skin by an infected tick, the spirochete must enter the bloodstream so that it can circulate in the blood to gain access to its target organs.The host doesn't sit idly as B. burgdorferi establishes an infection.  Invariant natural killer (iNKT) cells are one of the tools deployed by the immune system in its battle agains........

The great golden digger wasp, the Concorde fallacy, and free will

by Ryan Kitko in Cunabulum

Sphex ichneumoneus, the great golden digger wasp, about to enter her burrow.A few weeks ago, I noticed some alarmingly large insects that resembled wasps outside the front entrance of the biology building at Kenyon College. They would fly a few centimeters above the sandy gravel, no doubt surveying the best landing spot. Only a handful of these solitary wasps were here hovering over at least a dozen wasp-diameter holes in the loamy soils under this protected overhang. Suddenly, one landed and di........ Read more »

Are most experimental subjects in behavioral science WEIRD?

by Michael Meadon in Ionian Enchantment

My supervisor David Spurrett and I have a commentary on an important paper - "The weirdest people in the world?" (pdf) - in the most recent edition of Behavioral & Brain Sciences. The authors, Canadian psychologists Joseph Henrich, Steven Heine and Ara Norenzayan, argues that most experimental subjects in the behavioral sciences are WEIRD - Western, Educated, Industrialized, Rich, and Democratic - and thus weird - not representative of most human beings. And thi........ Read more »

How to maxmize your happiness from a vacation.

by Psychothalamus in Psychothalamus

I am sure that most, if not all of us would agree that going on a vacation makes us happy. But are we really happier than people who are not going for a holiday? And if we are indeed happier, how long do these effects persist and how does the length of our vacation and amount of holiday stress impact our happiness levels? These are some of the questions that Nawijn, Marchand, Veenhoven & Vingerhoets (2010) attempt to answer.Their main findings are listed below.Pre-trip happiness: Vacationer........ Read more »

Why moss blows smoke rings

by Thomas Kluyver in Thomas' Plant-Related Blog

Science via Youtube today. Let’s start with some smoke rings.  They go an impressively long way—much further than a simple puff of smoke fired with the same force would: So, why might a moss need to do the same thing? It’s all about spores. Mosses spread by spores, a bit like microscopic seeds. For peat [...]... Read more »

MDMA for PTSD: The first peer-reviewed clinical trial report

by DrugMonkey in DrugMonkey

My readers will recall that I have blogged now and again about ongoing efforts to get 3,4-methylenedioxymethamphetamine (MDMA), the psychoactive compound preferentially sought as Ecstasy in recreational users, approved as a medication to be used in psychotherapy. The initial attempts have focused on the treatment of Post-Traumatic Stress Disorder. PTSD is a seriously debilitating condition and we may not have sufficient resources and knowledge to deal with, e.g., an anticipated uptick due to the........ Read more »

Hippocampal ripples and memory consolidation

Major depression associated with impaired processing of emotion in music?

by Maria P. in noustuff

Previous studies have found that the processing of faces and voices is negatively biased in major depression. Naranjo and colleagues were the first to investigate possible effects of major depression on the recognition of emotion in music. According to the authors: as music is not directly linked to interpersonal communication, comparing a musical task with [...]... Read more »

Autism Spectrum Predicts Poor Outcome in Anorexia Nervosa

by William Yates, M.D. in Brain Posts

Few studies have examined the long-term outcome after the diagnosis of anorexia nervosa.  Fewer still have focused on adolescent-onset anorexia nervosa.Wentz and colleagues from Goteborg Sweden conducted a case-control study of 51 girls with anorexia nervosa with an average age of onset of 14 years old.Outcome studies in eating disorders often vary based on the site of recruitment.  Community samples typically have the most favorable prognosis followed by those identified in outpatient........
