Did Dogs Gain Their Social Intelligence By Accident?

by Jason Goldman in The Thoughtful Animal

I will be reposting some dog-related posts from the archives in the coming few weeks as I prepare for the course I'm teaching this semester on dog cognition. Please let me know if you find something inaccurate or unclear.

Domesticated dogs seem to have an uncanny ability to understand human communicative gestures (see here). If you point to something the dog zeroes in on the object or location you're pointing to (whether it's a toy, or food, or to get his in-need-of-a-bath butt off your damn be........ Read more »

Adipose Tissue Inflammation Promotes Diabetes?

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Regular readers will know that obesity is the major driver of the world-wide diabetes epidemic. But not everyone who is overweight will ultimately get diabetes.
So why do some people with excess fat become diabetic while others don’t?
Since the discovery that some people show marked signs of inflammation in their fat depots, researchers have suggested that [...]... Read more »

Repost – Unique Fossils Record the Dining Habits of Ancient Sharks

by Laelaps in Laelaps

Shark attacks are events of speed and violence. When they have locked-on to a prey item, sharks seem to come out of nowhere, and though they can be quite gentle with their jaws (as on occasions when they are unsure about whether something is food or not) their ranks of serrated teeth can inflict a [...]...

Song memes

by Zen Faulkes in NeuroDojo

Over thirty years ago, Richard Dawkins coined the term “meme” in his classic book The Selfish Gene. A meme was analogous to a gene. A gene is a physical replicator that multiplied itself (but with variations), in such a way that permitted selection and evolution. A meme, Dawkins wrote, was an intellectual replicator that could also multiple itself, creating variants as it did so, allowing evolution.

About two years ago. Susan Blackmore complained that people weren’t taking mimetics seriou........ Read more »

Intrinsic and Extrinsic motivation for exercise

by PhD Blogger in Exercise Psychology

OK, so when was the last time you saw a public health campaign which tried to increase physical activity levels by targeting intrinsic motivations to exercise? I personally cant think of any I've seen!  Motivation for exercise can be defined as intrinsic or extrinsic.  Intrinsic motivations for exercise are behaviours that are performed for the satisfaction gained in the activity itself.  Deci and Ryan (1985) argue that intrinsic motivations are commonly those of competency, int........

Beach House Chicks

by Journal Watch Online in Journal Watch Online

What could be better than a nice view of the surf, a little sand — and survival? Australian researchers have found that providing threatened shorebirds with simple A-frame “chick houses” made from plywood can dramatically increase the survival of young birds. But they aren’t sure exactly why the avian architecture helps.
The Hooded Plover (Thinornis […] Read More »... Read more »

POSS Dendrimers for Drug Delivery

by KJHaxton in Endless Possibilities v3.0

Drug delivery is an area of research on the border of pharmaceutical science and medicinal chemistry.  My experience of drug delivery is mainly concerned with using polymers to devise new ways of getting approved drugs into the human body.  For example, a drug used in chemotherapy may well have extensive side effects when administered to a patient by intra venous infusion, yet [...]...

The middle path

by Becky in It Takes 30

Drug discovery tends to happen via one of two main ways.  Either you look for a phenotypic effect — as in, chewing that willow bark eased my headache, or this fungal extract stopped my rat liver membrane prep from making cholesterol — or you look for a specific effect on a purified target.  Both have [...]...

Identifying important Activities within the SCOR Process Categories

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

The Supply Chain Operations Reference (SCOR) model has been developed by the Supply Chain Council to provide a best-practice framework for supply chain management practices and processes with the goal to increase performance.

The SCOR model consists of five major process categories: Plan, Source, Make, Deliver and Return
Starting from that best practice processes are defined up to level three. Supply Chain Operations Reference Model (SCOR, SCC 2000)

Article Review: Online professionalism

by Michelle Lin in Academic Life In Emergency Medicine

A recent editorial nicely summarized the challenges that the medical profession faces with the popularity of social media platforms. As physicians and other medical providers are coming to realize, whenever you post something to Facebook, Twitter, YouTube or a blog, you are creating a "digital footprint". In essence, think of yourself as "treading" through the World Wide Web and every action that you take leaving a lasting "footprint". There are definite potential landmines for physicians who e........ Read more »

Healthy Dads, Healthy Kids, and Unhealthy Peer Review.

by Yoni Freedhoff in Weighty Matters

Last week Colby Vorland tweeted a link to a new study that looked at the impact of a lifestyle modification program geared at overweight fathers and their children.The study set out to randomly investigate something called the Healthy Dads, Healthy Kids Program - a 3 month program that delivers 10 hours of behavioural change counseling to overweight dads and their kids (where the kids showed up for 4 of those). The study looked at dads' and kids' weights at the end of the program and 3 months l........ Read more »

In a recent letter to the editor of journal Bioinformatics Marabotti and Facchiano have raised the concern over the misuse of term ‘homology’ in peer-reviwed bioinformatics papers. This issues is not new for the scientific community at all, in fact severity of the issue was first recognized in 1987 when a letter to the Editor [...]

trouble with biomarkers and press releases

The latest issue of the Journal of Neuroscience contains an interesting article by Ecker et al in which the authors attempted to classify people with autism spectrum disorder (ASD) and health controls based on their brain anatomy, and report achieving “a sensitivity and specificity of up to 90% and 80%, respectively.” Before unpacking what that [...]...

As I’m getting on in my study I’ve found that people (outside of uni) treat me as something of an expert on all things ‘brain’.

How well do we really communicate?

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

I’m pretty sure most clinicians want to believe that they treat people with equal respect, that they listen carefully and respond with empathy when a person has concerns about their health. At the same time I’ve listened to many people with chronic pain describe how they’ve had trouble feeling heard, how they can feel like … Read more... Read more »

Explaining temporal resolution with water-works of the visual system

Most people are confused about temporal resolution. That includes my students, and even BBC science programmes. So I created this diagram to communicate the basic concept, with the example of human visual processing, using a water-works metaphor. Why water-works? I’m trying to explain an unfamiliar concept in terms that everyone can understand intuitively. By using [...]... Read more »
