An epigenetic mechanism for peripheral insulin resistance

by Colby in

PGC-1alpha is my favorite gene/protein to study, as it is essential for mitochondrial regulation, influential on many diseases and ageing.  I also am fascinated by the relatively new field of epigenetics and its relation to nutrition and health.  So you can understand my geeky giddiness when I found that a study by Barrès et al. (1) shows [...]... Read more »

East is East?

by Alun in AlunSalt

I’m not planning to blog a lot on the Astronomical Orientation of Ancient Greek Temples as is openly accessible. Your comments are going to carry a lot more weight there than here. But I’ll try and keep track of what other people are saying elsewhere. I’m expecting this to be the first paper of a [...]... Read more »

Homeopathy really doesn’t work

by sciencebase in Sciencebase Science Blog

A couple of years ago, I re-posted an old article of mine about homeopathy discussing its ludicrous claims, its feeble attempts to provide a scientific explanation for those claims, and basically pointing out that no solid evidence has ever been found that infinitely diluted solutions of spurious ingredients have any more beneficial effect on a [...]Homeopathy really doesn’t work is a post from: Sciencebase Science Blog

Want to predict a footie result? Don't even think about it

by Christian Jarrett in BPS Research Digest

Imagine you've just paid an expert good money for their verdict and they say to you: "Can you hang on a couple of minutes whilst I don't think about this". You'd be forgiven for thinking they've gone silly. They may have. But another possibility is that you've chosen a shrewd expert who's totally up-to-speed with the latest decision-making research: Ap Dijksterhuis and his colleagues have just shown that people with expertise in football are better at predicting match outcomes when they spend ti........

A model of executive functioning and stress regulation

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

I’m a visual kind of girl, I need to see a diagram to help me conceptualise how the things I’ve been writing about recently all fit together. I’ve been looking at the various aspects of self regulation, emotions and executive functions and how this affects and is affected by stressors, of which chronic pain [...]... Read more »

Lying on Adolescents’ Blogs

by Dr Shock in Dr Shock MD PhD

Adolescents are the most truthful about school and their life on blogs, whereas they are the least truthful about intimate topics such as family life and partnership. Adolescents present their personal information on blogs very truthfully. A girls of fourteen is really a girl of fourteen.
During adolescence forming an identity is a key developmental task [...]

The Benefits of Increased PGC-1alpha Expression

by Reason in Fight Aging!

A short introduction to the gene PGC-1alpha: this is one of a number of genes of interest involved in the biochemical changes, resistance to age-related disease, and extended healthy life span brought about by calorie restriction (CR). It favorably changes the operation of mitochondria, and based on the effects of other genes and proteins involved in these mechanisms, I would expect enhanced expression of PCG-1alpha to have at least some modest beneficial effect on life span. That said, I'm not ........ Read more »

Tobacco harm reduction - no smoke without fire

by Martin Robbins in The Lay Scientist

Smoking kills millions of people every year and yet the medical community seems pathologically opposed to any measure to tackle the issue other than through the promotion of total abstinence. Carl Phillips suggests in his paper in the Harm Reduction Journal this month that smoking for just one month is more dangerous than switching to a smokeless nicotine product for a lifetime.
Take a moment to take a deep drag on a few breathtaking statistics.
Across the world approximately 1........ Read more »

Oh no! Ideophones are not response cries!

by Mark D. in The Ideophone

In their commentary on Evans & Levinson's recent hotly debated Myth of Language Universals paper, Pinker & Jackendoff briefly mention ideophones — and erroneously shelve them away as 'response cries'. It seems this error is a particularly easy one to make for speakers of SAE languages. In this post I flesh out why this might be so, and explain what's the difference between response cries (also known as interjections) and ideophones.... Read more »

Not just a pretty face: The facial ruff of barn owls and sound localisation

by kubke in Building Blogs of Science

Barn owls are the subject of many studies on auditory neuroscience because of their exquisite ability to localize sound. The auditory system is interesting from a neuronal computation point of view because the inner ear, where sounds are detected, relays no information to the brain as to the location of the sound source in space.

Stress: The final frontier (executive functions)

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

It’s visceral. Stress – hits you in the guts. Some of us cope well, some of us don’t – some of our stress lingers, sometimes it’s just the little things, those ‘daily hassles’ that end up tripping the switch. And I don’t think anyone would disagree that chronic pain is an enormous stressor. [...]... Read more »
