Study Tests Theory that Life Originated at Deep Sea Vents

by Perikis Livas in Tracing Knowledge

One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about exactly how life began. One possibility has grown in popularity in the last two decades – that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world.

Gluten exposure and "feelings of depression"?

by Paul Whiteley in Questioning Answers

Could exposure to dietary gluten affect a person's moods or emotional state?Well, if the paper by Simone Peters and colleagues [1] (open-access here) is to be believed the answer may very well be yes, at least in some cases, as they report a link between gluten consumption and feelings of depression under [short-term] experimental conditions. If replicated, such a finding may have profound consequences for how we view our relationship between food and mental health and wellbeing.Bread Ma'am?&nbs........ Read more »

Atheists and Their Capacity for Awe at Life

by Scott McGreal in Eye on Psych

Many people think of awe as a particularly religious emotion and therefore seem to assume that people with no religious beliefs at all, e.g. atheists are closed to the experience of awe. This assumption is quite false and reflects a wider prejudice against atheists. Research has shown that people who reject supernatural beliefs actually are capable of experiencing a sense of awe. In fact, the experience of awe may be particularly beneficial for those who do not believe in an afterlife.... Read more »

Why do I procrastinate? I'll figure it out later

by in Neuroscientifically Challenged

If you are a chronic procrastinator, you're not alone. Habitual procrastination plagues around 15-20% of adults and 50% of college students. And, depending on the nature of the responsibilities one is neglecting, procrastination can have consequences. In a chronic procrastinator, repeated failure to efficiently complete important tasks can lead to lower feelings of self-worth. In certain contexts, it can also result in very tangible penalties. For example, a survey in 2002 found that 29% of Amer........ Read more »

Journal Club: Telomere length: a new measure of chronic stress in wildlife?

by GrrlScientist in Maniraptora

SUMMARY: Two independent studies find a positive relationship between social environment and telomere length. The first study -- that nearly everyone has heard about -- is in children. The second study -- that few have heard about -- is in pet grey parrots. The second study raises the question: might telomere length be developed as a new way to measure chronic stress -- in animals? ... Read more »

Lusty Worms Pass Love Notes through Tiny Bubbles

by Christina Szalinski in ASCB Post

Researchers recently reported that the laboratory system model worm, Caenorhabditis elegans, releases tiny extracellular vesicles (ECVs) that impact mating behavior in other worms. This is a radically new function for ECVs, which are generally thought to communicate between cells within an organism. This is the first time ECVs have been shown to be a means of communication between separate organisms.... Read more »

Telomere length: a new measure of chronic stress in wildlife? | @GrrlScientist

by GrrlScientist in GrrlScientist

Telomeres, the DNA-protein caps that prevent chromosomal fraying, are positively affected by social stress, according to two independent studies that were just published within days of each other. One study -- which has received widespread media coverage -- found a positive relationship between social environment and telomere length in children, adding support to previous work in people. A second study -- which few have heard about -- found that accelerated telomere erosion is associated with so........ Read more »

Capsaicin – Adding To Or Taking Your Pain

by Mark Lasbury in As Many Exceptions As Rules

Activation of TRPV1 ion channels can lead to potentiation of noxious stimuli while activation of multiple nociceptors can result in sensitization of TRPV1. Both situations can lead to hyperalgesia or allodynia. New research is highlighting the role of TRPV1 in burning mouth syndrome, both in its hyperalgesic and allodynic symptoms, as well as in its treatment. ... Read more »

Do As I Do: Copy Cat Social Imitation in Dog Training

Join us for another guest post, this time from Claudia Fugazza of the Family Dog Project in Budapest. Claudia's here to discuss her recent publication in Applied Animal Behaviour Science on the efficiency of new methods in dog training.Hi Mia and Julie,Formal training methods used until now rely mainly on the well-known rules of individual associative learning. These methods work perfectly well for a very wide range of animals — pigeons, rats, dogs and even crabs — and human and non-human an........ Read more »
