Alzheimer’s Disease and Insulin Resistance

by Shaheen Lakhan in Brain Blogger

For years, researchers have noted a connection between conditions of impaired insulin use and regulation, such as obesity and type 2 diabetes, and Alzheimer’s Disease (AD), but the mechanism of association has not been well-defined. Now, researchers report that proteins that influence the development and progression of AD are suppressed by insulin, encouraging new treatment [...]... Read more »

Tuesday Crustie: Know that I glory in this nose of mine

by Zen Faulkes in NeuroDojo

I was pleased that people liked last week’s description of a new squat lobster and its whimsical name, Uroptychus pinocchio. Today, let me introduce its cousin, another  species new to science with an equally choice nom de science:

Like its relatives, Uroptychus naso and Uroptychus pinocchio, this new species lives in the western Pacific. These three are distributed from Japan in the north down to Australia in the south. Something interesting happens as you travel along this way on the ........ Read more »

Today in arXiv (2)

by Marco Frasca in The Gauge Connection

Today I have found some papers in the arXiv daily that makes worthwhile to talk about. The contribution by Attilio Cucchieri and Tereza Mendes at Ghent Conference “The many faces of QCD” is out (see here). They study the gluon propagator in the Landau gauge at finite temperature at a significantly large lattice. The theory [...]... Read more »

Ecological footprint feedback can make some people less green

by BPS Research Digest in BPS Research Digest

The benefit of ecological footprint questionnaires for the environmental movement seems obvious enough, especially since the vast majority of people say they care about the planet. For most Westerners, their results on such a questionnaire are sobering, informing them about the unsustainability of their lifestyles. And that, you'd think, would lead them to start behaving in more environmentally friendly ways. Trouble is, it's been shown that if changing their behaviour seems too difficult, many ........

Ingroups, Identities, and In-Memoriams: Why We Must Remember Never To Forget

Part 2 Building Design: Fooling people into taking the stairs

by Megan Carter in Verdant Nation

I just got back from a conference in Montreal – one on obesity at that. The hotel, the location for the conference, held sessions on floors 1-4 and on sub floors below the lobby – ample opportunity to use the stairs.  There were two main problems: 1) the stairs were confusing – you’d get up to one floor but then couldn’t find the next set of stairs to the next floor and have to walk quite a distance to get to them; and 2) there were escalators in between these floors in plain sigh........

“Psychological stuff isn’t in my scope of practice” so what can I do?

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

A common cry from various clinicians who work in the field of pain management but who are not psychologists is “but now what?” when they recognise that a key factor in recovery is something psychosocial. The answer is not, I suspect, heading off to become a psychologist! For several reasons, I think it’s critical for … Read more... Read more »

Things to kill when you're original, affluent and social...

by Julien Riel-Salvatore in A Very Remote Period Indeed

I have to admit this made me laugh.


So, it's kind of a silly comic, definitely good for a few chuckles. Yet, when you take a second to think about it, there's a lot packed into it. In two little panels, the cartoonist manages to bring up two of the biggest misconceptions about prheistoric hunter-gatherers: 1) that hunter-gatherers spend only a small amount of ... Read more »

Mortality among users of marijuana, cocaine, amphetamine, ecstasy and opioids

by dj in Neuropoly

While Illicit drugs have long been linked to higher mortality rates, the data is wildly variable. In a paper recently published in the journal Drug and Alcohol Dependence, Danish researchers attempted to establish standard mortality ratios for the drugs cannabis, cocaine, amphetamine, MDMA (ecstasy) and opioids (e.g. heroin)*, while taken into consideration the effects of [...]...

What would you do about an old bridge?

by Jon Wilkins in Lost in Transcription

So, what would you do if faced with an old-style concrete bridge that does not really have the strength that it should?

One solution has been proposed in a PhD dissertation by Gun Up Kwon of the University of Texas. Of course, this post is only marginally about that, but there you go.

These full-size episodes tend to come out poorly on the blog, so if you want to be able to read it more easily, I recommend heading over to Darwin Eats Cake.

Manganese as a Recorder of Hypoxia

by Dan in The Endolymph

I haven't been doing much writing about otoliths lately (at least not here), despite the goal of this blog being to write about otoliths.  In fact, recently I have been writing more about invasive species, which is a topic I absolutely hate!Really the only excuse I can come up with for not writing about otoliths is laziness.  I wanted to write about otoliths, I really did, I just needed some inspiration...which came in the form of some current events.  My interest was peaked when........

Convert Your Conspiracy Theorists: Research Shows it Can Be Done

by Persuasion Strategies in Persuasive Litigator

Those who count on the human ability to prioritize reason and evidence over unshakable conviction -- and all participants in the litigation process ought to count themselves in that group -- should take note of the persistence of questions over the President's place of birth, and the sad take-away that proof can be no match for a committed theory. The tendency to cling to conspiracy theories and other beliefs long after they've been refuted points to an underlying psychological need for cogniti........ Read more »

Designer Genes for Special Bacterial Lifestyles

by Moselio Schaechter in Small Things Considered

by S. Marvin Friedman

Thanks to the extensive research of the past ten years, we've become aware that many prokaryotic endosymbionts and habitual intracellular pathogens have undergone genome reduction over evolutionary time. Characteristic of this process, termed reductive convergent evolution, is the discarding of genes involved in metabolic pathways and regulatory functions that have become superfluous now that cells can scavenge host nutrients. The high percentage of noncoding DNA (includin........ Read more »

Easily distracted? Chances are you're not one of those young kids.

When we think of demographics that are easily distracted, we tend to think of younger generations, people on their phones over dinner or texting while driving, or only listening to you with one ear while they listen to their ipod with the other. But when we're talking about cognitive tasks like working memory, the ability [...]... Read more »

The vaccination does make the baby cry, so why do it?

by Greg Laden in Greg Laden's Blog

It seems like every time I take Huxley (now 18 months old) to the doctor, the following things happen: 1) Somebody says "Well, he won't need to get stuck with any needles for a long while now .... his next scheduled immunization is [insert phrase indicating 'a long time into the future']"; and 2) Huxley gets stuck with some needles.

The last time, a few days ago, was especially bad. Read the rest of this post... | Read the comments on this post...... Read more »

Proving Einstein Wrong...ish: Measurement of the Instantaneous Velocity of a Brownian Particle

by Chad Orzel in Uncertain Principles

Last summer, there was a fair bit of hype about a paper from Mark Raizen's group at Texas which was mostly reported with an "Einstein proven wrong" slant, probably due to this press release. While it is technically true that they measured something Einstein said would be impossible to measure, that framing is a little unfair to Einstein. It does draw media attention, though...

Transcranial Direct Current Stimulation: An Update

by Dr Shock in Dr Shock MD PhD

It’s been a while since I posted a blog article on transcranial direct current stimulation. Probably not an exciting new therapy for psychiatric conditions but a exciting oportunity to study the actions of certain brain parts and a way of influencing these superficial parts of the brain. You can see the procedure in a video [...]
