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 »

How Clever Do You Think Your Dog Is?

by CAPB in Companion Animal Psychology Blog

Maybe as smart as a four year old child?Photo: DragoNika / ShutterstockCanine researchers have been investigating dogs’ cognitive abilities: whether they can solve puzzles, recognize our emotions, and so on. But are ordinary people aware of these findings, and do they have a realistic view of dogs? A paper by Tiffani Howell (Monash University) et al investigates owner’s beliefs about their dog’s intelligence.The research, published in the Journal of Veterinary Behavior, involved a web surv........

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

by Cobb & Hecht in Do You Believe In Dog?

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 »

Too trusting? You are likely also cursed with intelligence and good judgment!

by Doug Keene in The Jury Room

We often associate people who are especially trusting with gullibility, low self-esteem, and lower intellectual function. However, we seem to have it backwards according to new research (which successfully replicates the results of studies from 2010 and 2012).  Intelligent people are more likely to trust others while those lower in intelligence are less likely to […]

Photographic analysis of a Shabe Yoruba burial

by JB in Bone Broke

When you’re one of the only bioarchaeology grad students in a department with few other osteologists, almost anything involving human remains will eventually make its way across your desk. After getting back to the museum in early September, fellow graduate student Andrew Gurstelle told me that he had come across a burial this past summer, and asked me whether I would mind taking a look at it if I had the time. I was initially extremely excited because I thought this would involve hands-o........ Read more »

The Lure of the Ring—A Chloride Ion Channel Gene Makes a Surprise Appearance in Ciliogenesis

by John Fleischman in ASCB Post

Basic—and unexpected—discoveries about the primary cilium are still being made. In the latest issue of Molecular Biology of the Cell, Chelsey Chandler Ruppersburg and H. Criss Hartzell of Emory University report that ANO1 (also known as Tmem16A), a gene encoding a calcium-activated chloride channel (CaCC) known to be involved in epithelial fluid secretion, has a unsuspected secret life early in the interphase of the cell cycle. ...
